XL97: How To Display a Progress Bar with a UserForm

• Microsoft Excel 97 for Windows

SUMMARY

If you have a Visual Basic for Applications macro that requires a long period of time to complete, you may want to give your user an indication that the macro is progressing normally. This article contains an example that illustrates how to create a progress bar with a UserForm.

MORE INFORMATION

In the following example, a Visual Basic subroutine populates a large range of cells with a random number. This task will take several seconds to complete; the indicator gives you an indication that the macro is running normally.

             UserForm1.LabelProgress.Width = 0
   
             ' Call the main subroutine.
             Call Main
         End Sub 




3. On the Insert Menu, click Module.



4. In the Code window for the module, type the following code:

             UserForm1.Show
         End Sub
   
         Sub Main()
             Dim Counter As Integer
             Dim RowMax As Integer, ColMax As Integer
             Dim r As Integer, c As Integer
             Dim PctDone As Single
   
             Application.ScreenUpdating = False
             ' Initialize variables.
             Counter = 1
             RowMax = 100
             ColMax = 25
   
             ' Loop through cells.
             For r = 1 To RowMax
                 For c = 1 To ColMax
                     'Put a random number in a cell
                     Cells(r, c) = Int(Rnd * 1000)
                     Counter = Counter + 1
                 Next c
   
                 ' Update the percentage completed.
                 PctDone = Counter / (RowMax * ColMax)
   
                 ' Call subroutine that updates the progress bar.
                 UpdateProgressBar PctDone
             Next r
             ' The task is finished, so unload the UserForm.
             Unload UserForm1
         End Sub
   
         Sub UpdateProgressBar(PctDone As Single)
             With UserForm1
   
                 ' Update the Caption property of the Frame control.
                 .FrameProgress.Caption = Format(PctDone, "0%")
   
                 ' Widen the Label control.
                 .LabelProgress.Width = PctDone * _
                     (.FrameProgress.Width - 10)
             End With
   
             ' The DoEvents allows the UserForm to update.
             DoEvents
