Web Browsing within Access Form

a.p.r. pillaiDecember 28, 2009Forms, msaccess controls 2 comments

Introduction

Browsing the World Wide Web is nothing new to us. But, how about organizing the Web Addresses of frequently visiting Websites in a Table and browsing the Web from within an Access Form?

Not only Internet Sites, but you can also browse the Intranet Website within your Local Area Network (Corporate LAN) too. All you have to do is to create an Access Form with a Microsoft Web Browser Control and a few lines of VBA Code.

For example, the following VBA Code will open the Gmail Web Site http://www.gmail.com/ automatically when you open the Form with the Web Browser Control, as shown in the above image.:

Simple Website Opening Code

Private Sub Form_Load()
Dim strURL As String

strURL = "http://www.gmail.com/"
Me.WebBrowser0.Navigate strURL
End Sub

Designing a Form for Web ActiveX Control

Don't know how to do it? Try the following:

Open a new Form in Design View.
Click somewhere on the Detail Section of the Form to select that area.
Select the ActiveX Control from Insert Menu.
Look for the name Microsoft Web Browser in the displayed list of ActiveX Controls and select it.
Click OK to insert a Web Browser Control on the Form.
While the Control is still in the selected state drag the right-bottom-corner sizing control to make it big enough on the Form so that you can view the Web Pages properly.
Display the Property Sheet of the Browser Control (View - ->Properties).
Change the Name Property Value to WebBrowserO to match with the name used in the above VBA Code.
Select Code from View Menu to display the VBA Code Module of the Form.
Copy and Paste the above Code into the Module.
Save and Close the Form with the name myWebBrowser.

Demo Run of the Form
Connect your PC to the Internet.
Open myWebBrowser Form in normal View.
Wait for a few seconds to load the Web Page into the Control and to display.

We have used the Website Address directly in the Code. But, if you create a table with the list of all the Website addresses that you visit very often then with a Combo Box on the Form we can select the Web address to go to that site quickly. We need to make a few changes to the above code to make it flexible.

Table with Frequently Visiting Web Addresses

Create a Table with a single field with the following details:
Table Name: WebSites
Field Name: Web Address Data Type: Text Field Size: 255
Save the Table Structure and open it in Datasheet View.
Add a few records with Web URLs that you visit frequently, and save and close the Table.
Make a copy of the Form myWebBrowser and name the copy as myWebBrowser2.
Open myWebBrowser2 in Design View.
Display the Form Header Section (View - -> Form Header/Footer), if it is not already Visible.
Expand the Form Header Section with enough height to create a Combo Box Control.
Create a Combo Box using the Web Sites Table.
While the Combo Box is still in the selected state display the Property Sheet (View - -> Properties).
Change the following Property Values of the Combo Box:
- Name : cboWeb
- Width : 5"
- Default Value: "http://www.gmail.com/" or any other Website Address Value you prefer.
Select the child label attached to the Combo box and change the Caption Property Value to Web Address:
Display the Code Module of the Form (View - -> Code).

Copy and Paste the following Code into the Module, replacing the existing lines.

Form Module Code

Option Compare Database
Option Explicit

Dim WebObj As WebBrowser
Dim varURL As Variant

Private Sub cboWeb_Click()
     GotoSite
End Sub

Private Sub cboWebLostFocus()
     GotoSite
End Sub

Private Sub Form_Load()
     Set WebObj = Me.WebBrowser0.Object
     GotoSite
End Sub

Private Function GotoSite()
    varURL = Me!cboWeb
If Len(Nz(varURL, "")) = 0 Then
    Exit Function
End If

WebObj.Navigate varURL

End Function

Save the Form and open it in Normal View.
The website address that you have inserted into the Default Value Property of the Combo Box will open up in the Browser Control.
Select one of the other website addresses you have added to the Table from the Combo Box.
The Browser Window will open the new Website.

If we open other Web Pages by clicking on the Links from the displayed page, then we can navigate (go Back or Forward) between pages by adding a few more lines of code.

Review of the VBA Code.

But, first, let us have a look at the above code to see what is happening there. We have declared a Web Browser Object Variable and a Variant Variable at the Global declaration area of the Module.

Created a separate Function GotoSite() to respond to different Events (Actions) on the Form without duplicating the code everywhere.

For example: when we open the Form the GotoSite() Function opens the Default Value URL, which we set in the Combo Box Property, through the Form_Load() Event Procedure.

When you select a URL from the Combo Box the cboWeb_Click() Event Procedure calls this Function to open the selected Web Page.

If you type a URL in the Web Address control cboWeb and move the Cursor out of the control the Lost_Focus() Event Procedure runs the Function to open the URL you typed in the Address Control.

We will create a few Command Buttons on the Header of the Form, as shown to the right of the Combo box Control on the above design, and write Subroutines with some simple Browser Object Commands to navigate between Web Pages, which we may open from the displayed Web Pages.

Web Navigation Controls

Open myWebBrowser2 Form in Design View.
Display the Toolbox (if it is not visible then select Toolbox from View Menu.
Create five Command Buttons to the right of the Combo Box.
Display the Property Sheet of the first Command Button and change the Name Property and Caption Property Values to Home.
Similarly, change the Name and Caption Property Values of the other Command Buttons with the values given below.
- Back
- Forward
- Refresh
- Stop
Display the Code Module of the Form (View - ->Code), copy and paste the following code into the VBA Module, below the existing Code lines.

Private Sub Home_Click()
On Error Resume Next
    WebObj.GoHome
End Sub

Private Sub Back_Click()
On Error Resume Next
    WebObj.GoBack
End Sub

Private Sub Forward_Click()
On Error Resume Next
    WebObj.GoForward
End Sub

Private Sub Refresh_Click()
On Error Resume Next
    WebObj.Refresh
End Sub

Private Sub Stop_Click()
On Error Resume Next
     WebObj.Stop
End Sub

The On Error Resume Next Statement prevents the Subroutines from running into Error when there are no Web Pages to Navigate to.

To test these Buttons you must click on a few links on the displayed Web Page to open other Pages from the same website and then use these buttons to navigate between those opened pages.

The Home Button will open the Default Home page you set in the Internet Explorer's Tools - -> Internet Options. . . Home Page - -> Address Control, not the default value you set in the Combo Box.

Text Search Filter Web Style

a.p.r. pillaiDecember 21, 2009Functions, Process Controls 6 comments

Introduction

How to search for several pieces of information across all the fields and in all the records of a Table?

For example, when we search for something on the Web we give several pieces of text separated by, or + symbol to match any of the given text anywhere within the Web Pages and display the matching links on the screen.

Search text example1: ms-access, forms, reports, Queries

Search text example2: ms-access+forms+reports+queries

In the same way, we can create filters to display records from a table that matches several pieces of Text/numbers/Phrases across any field in any record.

Last week we learned the use of the BuildCriteria () Function to filter data using only one field. BuildCriteria() Function can accept only one Field as its first Parameter. We will be using this Function here also. But, we will pull a trick for using this Function for all the fields in a Table.

A Simple Demo Run

So let us do this with a simple Query and a Tabular Form.

Import Customers Table from C:\Program Files\Microsoft Offce\Office11\Samples\Northwind.mdb sample database.
Create a Query using the Customers Table with all the fields and by adding a new Column with the name FilterField.
Write the following expression in the new column to join all the Text and Numeric Field values together into a single Column:

FilterField: [CUstomerID] & " " & [CompanyName] & " " & [ContactName] etc., join all the fields this way except HyperLinks, Objects, and Yes/No Field Types. Save the Query with the name myQuery.
This task you can automate with the following Program after creating a Query manually with at least one field from the Source Table and naming the Query as myQuery. You may modify the Program where the reference to myQuery name appears to implement your own preferred name if needed.
The CombineData() Code.
```
Public Function CombineData(ByVal tblName As String)
'----------------------------------------------------------
'Author : a.p.r. pillai
'Date   : December 2009
'Rights : All Rights Reserved by www.msaccesstips.com
'----------------------------------------------------------
Dim strsql1 As String, db As Database, qrydef As QueryDef
Dim fldName As String, k As Integer, j As Integer
Dim tbldef As TableDef, strjoin As String

On Error Resume Next

strsql1 = "SELECT " & tblName & ".*, "
Set db = CurrentDb
Set qrydef = db.QueryDefs("myQuery")

Set tbldef = db.TableDefs(tblName)
k = tbldef.Fields.Count - 1

strjoin = ""
For j = 0 To k
    If tbldef.Fields(j).Type <> 1 And tbldef.Fields(j).Type <> 11 And tbldef.Fields(j).Type <> 12 Then
        If Len(strjoin) = 0 Then
            strjoin = "[" & tbldef.Fields(j).Name & "] "
        Else
            strjoin = strjoin & " & " & Chr$(34) & " " & Chr$(34) & " &  [" & tbldef.Fields(j).Name & "] "
        End If
    End If
Next

strsql1 = strsql1 & "(" & strjoin & ") AS FilterField FROM " & tblName & ";"
qrydef.SQL = strsql1
db.QueryDefs.Refresh

Set tbldef = Nothing
Set qrydef = Nothing
Set db = Nothing

End Function
```
- Copy and paste the above VBA Code into a Standard Module and save it.
CombineData "Customers"
This will modify the design of myQuery by joining all the fields, except HyperLink, Object, Yes/No, and Memo Fields, from Customers Table, or any other Table that you use, and will create a new column with the name FilterField. If you need Memo Field contents too, then you must add that Field manually in Query design. The CombineData() Program will not do this because HyperLinks, Object & Memo fields fall into the same field Type category and the validation check bypasses it.
The Sample Datasheet view image of the FilterField in myQuery is given below:

Design a Form
Create a Tabular Form (continuous form) using myQuery as Record Source and save the Form with the name frmMyQuery.
Open the form frmMyQuery in the Design view.
Select the FilterField Column and display its Property Sheet (View - ->Properties)
Change the Visible Property Value to No.
Make the FilterField column size very small on the Form (it is not visible on normal view) and resize other Columns to view their contents properly.
Remove the columns like Region, Fax, etc., or any other column that you feel are not required for our Test Runs so that all the required columns will fit on one screen properly.
Expand the Form Header Section and drag the column headings down so that we will get enough space to draw a TextBox and a Command Button beside it.
Create a Text Box above the column headings.
Display the Property Sheet of the Text Box (View - ->Properties).
Change the following Property Values as given below:
- Name = txtSearch
- Width = 3"
Change the Caption of the Child Label of the Text Box to Search Text (delimiter:, or +):
Create a Command Button to the right of the Text Box and change the following Property Values:
- Name = cmdGo
- Caption = GO>
The Form's Class Module Code.
Display the Code Module of the Form (View - -> Code).

Copy and Paste the following VBA Code into the Module.

            flag = True
    ElseIf Xchar = " " And flag Then
            flag = False
            Y_Filter = Trim(Y_Filter)
    End If
    Y_Filter = Y_Filter & Xchar
Next
x_Filter = Y_Filter

Y_Filter = "*"
For j = 1 To Len(x_Filter)
        Xchar = Mid(x_Filter, j, 1)

                MsgBox "Invalid Characters () in expression, aborted... "
                Exit Sub
     End If
If Xchar = "," Or Xchar = "+" Then
'test for presence of ,+
     Xchar = "* OR *"
End If
Y_Filter = Y_Filter & Xchar
Next

Y_Filter = Y_Filter & "*"
Me.FilterOn = False
Y_Filter = BuildCriteria("FilterField", dbText, Y_Filter)
Me.Filter = Y_Filter
Me.FilterOn = True

End Sub

The Sample Demo Run.

Save the Form and open it in Normal View.
Type some Text/Numbers/Phrases separated with commas (,) or plus symbol (+), which can match in any part of any Field(s) or in different Record(s), in the Text Box.
Example1: FRANK, Elizabeth Brown, Brazil
Example2: FRANK+Elizabeth Brown+Brazil
Example3: frank+ Elizabeth Brown, Brazil
NB: Do not use brackets "()" in the search text. These will run into errors when used in the BuildCriteria() Function. Users may type extra spaces between the text separator character, or + symbol and the next search text item and these spaces will be removed by the program before going into search and filter operations. Embedded spaces in phrases will be left alone in the search text.
Click on the GO> Command Button to search for the given text in fields/records and filter those records on the Form.
You may inspect the filtered records to ensure that one or more of the search text you have entered into the Text Control appears in all the filtered records. They can appear in any field or fields in any Record, but all the records filtered will have these texts/numbers/phrases on them.

Filter with BuildCriteria Function

a.p.r. pillaiDecember 15, 2009Functions, Process Controls No comments

Introduction

Any method that helps to find data quickly on a Form is always welcome by Users. There are several options available when you are in Form View Mode.

When you Right-click on a Field a Shortcut Menu will pop up showing four data filter options as shown on the sample image given below.

The third option Filter For can accept a Criteria Expression like >10200 AND <=10300 or similar to filter a Range of Values from the selected field.

If you would like to see more options, then, point to the on-Filter option in Record Menu. There you can find two new Options: Filter by Form and Advance Filter/Sort. Filter by Form allows you to set up Criteria in more than one field to select records based on Form fields.

The Advanced Filter/Sort will open up the Filter Design (Query Design) Window with the Source Table/Query of the Form with whatever criteria you have entered into the Filter for or Filter by Form Options earlier if any. You can further modify the filter conditions and Sorting Order and select Apply Filter from the Records Menu to view the result.

But, if you would like to build a Custom Filter Option for the User; based on a particular field on the Form then you can use the built-in Function BuildCriteria() and write a VBA Sub-Routine around this Function to filter the data. Run the Sub-Routine on a Button Click Event Procedure and let the User input the Filter Criteria in various ways as he likes.

The Usage of the Function is very simple. Let us try a few examples of the Function directly in the Debug Window (Immediate Window) to understand how it works.

Press Alt+F11 to display the Visual Basic Editing Window.
Press Ctrl+G to display the Debug window.
Type the following example expressions and press the Enter key to display the output:

Sample Run of BuildCriteria() Function

? BuildCriteria("OrderID",dblong,"10200")

Result: OrderID=10200

The BuildCriteria() Function needs three Function Parameters. OrderID is the Data Field Name, dbLong indicates that OrderID is a Numeric Field with values of Long Integer Type and the last Value 10200 is the OrderID criteria value for selecting records. The OrderID Field Name will be inserted in appropriate locations in the Criteria expression by the BuildCriteria() Function.

The last parameter value we can use in several ways depending on how we want the result. Let us see a few more examples before we implement this method on a Form. Type the following expressions in the Debug Window to see how it works:

? BuildCriteria("OrderID",dblong, ">=10200 AND <10300")

Result: OrderID>=10200 And OrderID<10300

? BuildCriteria("OrderID",dblong,">=10200 AND <10300 OR >=10400 AND <10500")

Result: OrderID>=10200 And OrderID<10300 Or OrderID>=10400 And OrderID<10500

Try changing the data type to dbText, for example:

? BuildCriteria("OrderID",dbText,"10200")

Result: OrderID="10200"

? BbuildCriteria("OrderDate",dbDate,">10/15/2009 and <=10/31/2009")

Result: OrderDate>#10/15/2009# And OrderDate<=#10/31/2009#

Using on Form to Filter Data

After getting the result text from the BuildCriteria() Function all we have to do is to insert it into the Filter Property of the Form and turn ON the Filter action.

Let us design a simple Form to Run our example straight away.

Import the Orders Table from C:\Program Files\Microsoft Office\Officell\Samples\Northwind.mdb sample database.
Click on Orders Table to Select it and select Form from Insert Menu.
Select Auto Form: Tabular to create a Form and save it with the name Orders.
Open the Orders Form in Design View.
Expand the Form Header Area and drag all the Field Headings down to get enough room to create a Command Button above the Field Headings.
Display the ToolBox, if it is not visible (View - ->Toolbox).
Select the Command Button Tool and create a Command Button on the Header of the Form.
While the Command Button is still in the selected state display its Property Sheet (View - - > Properties).
Change the Name Property Value to cmdFilter and change the Caption Property Value to OrderID Filter.
Display the Code Module of the Form (View - -> Code).

Run it with a Button Click

Copy and Paste the following VBA Code into the Module.

Private Sub cmdFilter_Click()
Dim txtCondition, txtFilter As String

txtCondition = InputBox("OrderID Value/Range of Values")
If Len(txtCondition) = 0 Then
    Me.FilterOn = False
    Exit Sub
End If

txtFilter = BuildCriteria("OrderID", dbLong, txtCondition)

Me.FilterOn = False
Me.Filter = txtFilter
Me.FilterOn = True

End Sub

Save and Close the Form.
You may click on the OrderID Filter Command Button and enter any of the examples (except the one with Date) criteria expressions we have entered as the third Parameter into the BuildCriteria() Function above, when prompted for the Filter Condition.

Setting up Criteria Value on Text Box.

If you don't like to use InputBox() to prompt for Criteria Values then you may create a Text Box on the Form where Users can enter the Criteria expression before hitting on the Command Button.

The limitation of the BuildCriteria() Function is that it can accept only one field as the first parameter. But, there is a way to use more than one field in the Filter condition on the Form. Ask the User to enter conditions for two different fields separately and run the BuildCriteria() Function also separately to obtain the results. Join both results with AND/OR Logical operators to filter the data.

The following example code uses OrderID and ShipName field values to filter data on the Orders Form.

Create a Copy of the Orders Form and name the Form Orders2.
Open the Form in Design View.
Display the Code Module of the Form (View - -> Code).
Copy and Paste the following Code into the Module, replacing the existing Code:

Private Sub cmdFilter_Click()
Dim txtOrderNumber, txtOrderfilter As String
Dim txtShipName, txtShipNameFilter As String
Dim msg As String, resp, txtFilter As String

txtOrderNumber = InputBox("OrderID Value/Range of Values to Filter")
txtShipName = InputBox("ShipName/Partial Text to Match")

If Len(txtOrderNumber) > 0 Then
    txtOrderfilter = BuildCriteria("OrderID", dbLong, txtOrderNumber)
End If

If Len(txtShipName) > 0 Then
    txtShipNameFilter = BuildCriteria("ShipName", dbText, txtShipName)
End If

If Len(txtOrderfilter) > 0 And Len(txtShipNameFilter) > 0 Then
    msg = "1. Filter items-that matches both filter conditions" & vbCr & vbCr
    msg = msg & "2. Matches either one or Both conditions" & vbCr & vbCr
    msg = msg & "3. Cancel"
    Do While resp <> 1 And resp <> 2 And resp <> 3
        resp = InputBox(msg)
    Loop
    Select Case resp
        Case 3 
           Exit Sub
        Case 1
            txtFilter = txtOrderfilter & " AND " & txtShipNameFilter
        Case 2
            txtFilter = txtOrderfilter & " OR " & txtShipNameFilter
    End Select
Else
    txtFilter = txtOrderfilter & txtShipNameFilter
    If Len(Trim(txtFilter)) = 0 Then
       Exit Sub
    End If
End If

Me.FilterOn = False
If Len(Trim(txtFilter)) > 0 Then
    Me.Filter = txtFilter
    Me.FilterOn = True
End If

End Sub

How does it Work?

The first two InputBox() Functions collect the Filter Criteria for OrderID and ShipName Field values separately. Next steps Validate the User responses and Build the criteria strings in txtOrderFilter and txtShipNameFilter Variables.

If both Variables have filter conditions in them, then the User response is collected to check whether he/she needs the result set that meets both conditions (AND) or the result set that meets any one of the conditions or both (OR).

The Filter Strings are joined, accordingly to obtain the intended result. It is not necessary that the User should always provide both sets of Criteria Values (for Orderld and ShipName) all the time. They can use only one Field for entering Criteria and ignore the other.

Save User Specific Parameter values

a.p.r. pillaiDecember 07, 2009Forms, Process Controls 5 comments

Introduction

Last week we have prepared a Report Parameter Control Form for concurrent users on the Network without clashing with other User's Report Data Filter Parameter Values while preparing different Versions of the same Report. To do this we have discarded the usage of a Parameter Table as Record Source in the Parameter Form and created two Unbound Text Boxes for keying in Parameter Values for setting Filter condition in the Report Source Query. Besides that, we have seen how to save the Parameter Values in the Custom Properties of the Form, when the Form is closed.

The sample image of the Report Parameter Form: RptParameter is given below for reference:

Last week we have used the Parameter Control's Text Box Names FromDate and ToDate for entering Date-Range values as Criteria for filtering Data in Report Source Query. The Custom Property Names we have created giving slight changes to the Text Box Names, like DateFrom and DateTo.

One Question we raised last week was; is it possible to Save and Retrieve the Report Parameter Values set by each User on the fromDate and toDate TextBox Controls, in different instances of the same form, without getting overwritten by somebody else value? In last week's example, there is only one set of custom properties created for all the users and for all instances of the Form. The last user of the Network who closes his instance of the form will overwrite the Custom Property values of all other earlier instances and will be loaded back into the TextBox control next time when the form is loaded.

User-based Custom Property Name Format.

The solution is simple; create Custom Properties on the Form for each User and save the value set by him/her when their side instance of the Parameter Form is closed. To identify each User's value; add the User-Name along with the TextBox Name, to make the names unique, and create the Custom Property Name.

For example:

User-Name: JSmith
Parameter TextBox Name1: fromDate
Parameter TextBox Name2: toDate
Custom Property Name1: JSmithDateFrom
Custom Property Name2: JSmithDateTo

We can get the User Name of the current instance of the Form with the Function CurrentUser().

When the User-Name prefixes to the Custom Property Names we can easily save and retrieve individual User's parameter values and use them on their instance of the same Form as well.

Another point we have to keep in mind is that new users may be added to the same Workgroup and this method should work for them also when they start using the RptParameter Form.

We must write the VBA Routines in such a way that whenever a new user starts working with the RptParameter Form; the User must be identified as a newcomer and Custom Properties in that User must be created automatically, rather than creating it manually as we did in the earlier example.

The Custom Property Creation Code.

The modified Custom Properties creation Program is given below. Copy and Paste the code into a Standard Module of your Database.

Public Function CreateCustom_Property(ByVal frmName As String, ByVal usrName As String)
'-------------------------------------------------------------------------
' Author : a.p.r. pillai
' Date   : November-2009

Dim cdb As Database, doc As Document
Dim prp As Property, getPrpValue
Dim fld1 As String, fld2 As String

On Error Resume Next

fld1 = usrName & "DateFrom"
fld2 = usrName & "DateTo"

Set cdb = CurrentDb
Set doc = cdb.Containers("Forms").Documents(frmName)

'check whether the Property of the current user exists
getPrpValue = doc.Properties(fld1).Value

If Err = 3270 Then 
' referenced Property doesn't exist
    Err.Clear
'create Property for new User
    Set prp = doc.CreateProperty(fld1, dbDate, Date)
    doc.Properties.Append prp
    Set prp = doc.CreateProperty(fld2, dbDate, Date)
    doc.Properties.Append prp
    doc.Properties.Refresh
End If

Set prp = Nothing
Set doc = Nothing
Set cdb = Nothing

End Function

Create a Copy of the RptParameter Form with the name RptParameter2.
Open RptParameter2 Form in Design View.
Display the VBA Module of the Form (View - -> Code).

Revised VBA Code - Form Load.

Copy and Paste the following Sub-Routines into the VBA Module overwriting the earlier Code:

Private Sub Form_Load()
Dim cdb As Database, doc As Document
Dim fld1 As String, fld2 As String

fld1 = CurrentUser & "DateFrom"
fld2 = CurrentUser & "DateTo"

'Validate Current User's Status
'If, necessary create Custom Properties for new User
CreateCustom_Property Me.Name, CurrentUser

DoCmd.Restore

Set cdb = CurrentDb
Set doc = cdb.Containers("Forms").Documents(Me.Name)
Me![fromDate] = doc.Properties(fld1).Value
Me![toDate] = doc.Properties(fld2).Value

Set cdb = Nothing
Set doc = Nothing

End Sub

Revised VBA Code - Form Close.

Private Sub Form_Close()
Dim cdb As Database, doc As Document
Dim fld1 As String, fld2 As String

fld1 = CurrentUser & "DateFrom"
fld2 = CurrentUser & "DateTo"

Set cdb = CurrentDb
Set doc = cdb.Containers("Forms").Documents(Me.Name)

doc.Properties(fld1).Value = Me![fromDate]
doc.Properties(fld2).Value = Me![toDate]

Set cdb = Nothing
Set doc = Nothing
End Sub

Save and Close the Form.

Review of Programs.

As you can see from the Form_Load() Event Procedure that the Custom Property Creation Program CreateCustom_Property() is called only when the User (New or existing) opens the RptParameter2 Form. So, the Custom properties are not created for all the Users of the Database if their activity doesn't involve this particular Form.

The Report Parameter Form must be tested from different machines at the same time by different Users and set their own values in the Parameter Control Text Boxes: fromDate and toDate to try out the procedure. When the Form is open by the same Users next time the values set by them in the earlier session should appear in the fromDate and toDate Text Box Controls.

NB: The above Procedure is not extensively tested to trap Bugs or side effects and you may use it at your own risk. If you find any bugs or issues, please share them with me too. The procedure assumes that the Database is implemented with Microsoft Access Security.

Visit the Page: Unsecured Database and Users Log to find out how to get a User's Name when the shared database is an Un-secured one. In un-secured databases, the CurrentUser() Function will always return the User Name as Admin.
