VBA Module Object and Methods

VBA Module Object and Methods.

The VBA Module Object has several interesting methods and properties.  Last week, we saw how to insert a Click Event Procedure in a Form Module with a Function. You can find this blog post here.

I am not suggesting that the 'frm.Module.CreateEventProc()' method we explored for writing a one-line Event Procedure in a Form Module. However, trying different techniques is always worthwhile because programming is an exploration of new possibilities. After all, this method is available in the Access Application Object Model for us to explore and learn.

Today, we will examine an alternative and simpler approach to the same example we covered last week. Instead of creating the Event Procedure programmatically line by line, we will write the entire procedure in a text file and then load it directly into the Form Module.

If you have already tried last week’s example, we can use the same ‘Sample’ Form for today’s trial run,  or do the following to get prepared:

Loading VBA Code from Text File.

1. Open a new Form in Design View.

2. Create a CommandButton on the Detail Section of the Form.

3. While the CommandButton is selected, display its Property Sheet (F4 or ALT+Enter).

4. Change the Name Property Value to cmdRun and the Caption Property Value to Run Report.

5. Save the Form named Sample.

6. If you have last week’s Sample form, then open it in Design View.

7. Display the Form Module, remove the existing program lines, and save the Form.

8. Open Notepad, copy and paste the following program lines into Notepad, and save it as c:\windows\temp\vbaprg.txt: 

   Private Sub cmdRun_Click()
   
       DoCmd.OpenReport "myReport", acViewPreview
   
   End Sub

9. Replace the report name "myReport" with one of your own Report Names from the database.

10. Open a Standard VBA Module, copy and paste the following main program into the Standard Module:

    The LoadFromTextFile() Function.

    Public Function LoadFromTextFile()
    Dim frm As Form, frmName As String, ctrlName As String
    
    frmName = "Sample"
    'ctrlName = "cmdRun"
    
    'Open the form in design view
    DoCmd.OpenForm frmName, acDesign
    
    'define the form object
    Set frm = Forms(frmName)
    
    'call the form's Module Object's AddFromFile() method
    'to read the program from the text file
    'and insert them into the Form Module
    frm.Module.AddFromFile "c:\windows\temp\vbaprg.txt"
    
    'Save and close the form with the code
    DoCmd.Close acForm, frmName, acSaveYes
    
    'Open the form in Normal view
    DoCmd.OpenForm frmName, acNormal
    
    End Function

11. Place the cursor in the middle of the code, then press F5 to run the Code.

12. Press ALT+F11 to display the Database window with the Sample Form open.

13. Click on the Command Button to open the Report in print preview.

14. Close the Report.

15. Change the Sample Form in Design View.

16. Open the form module and check for the program lines we have loaded from the vbaprg.txt File.
