VBA to Create a Custom Progress Bar in UserForm - Unexpected Behavior with Timer
I'm learning this framework and I've spent hours debugging this and I'm currently trying to implement a custom progress bar in a UserForm using VBA for Excel. The goal is to provide visual feedback while a lengthy task is running. However, I'm encountering unexpected behavior where the progress bar does not update correctly during the execution of the task. Instead of showing a gradual progress, it jumps to the end once the task is completed. Here's a snippet of my current approach: ```vba Private Sub UserForm_Initialize() Me.ProgressBar.Value = 0 End Sub Public Sub StartTask() Dim i As Integer Me.Show vbModeless For i = 1 To 100 ' Simulating a lengthy process DoEvents Application.Wait Now + TimeValue("00:00:01") ' Simulate delay Me.ProgressBar.Value = i Next i Unload Me End Sub ``` I've tried using `DoEvents` to allow the UserForm to refresh, but it seems the `Application.Wait` method blocks the UI from updating. I also attempted to replace the `Application.Wait` with a loop that uses `Timer`, but the progress is still not reflected in real-time. Here's my alternative approach: ```vba Public Sub StartTaskWithTimer() Dim StartTime As Double StartTime = Timer Me.Show vbModeless Do While Timer < StartTime + 5 ' Simulate 5 seconds of work Me.ProgressBar.Value = (Timer - StartTime) / 5 * 100 DoEvents Loop Unload Me End Sub ``` Despite this, the progress bar still doesn't update smoothly. I've searched for resources on creating custom progress bars in UserForms, but most examples do not address the performance issues with the timer. Any suggestions on how to effectively implement a responsive progress bar in VBA? Are there better design patterns or practices I should consider? This is my first time working with Vba stable. Is this even possible? This is for a web app running on Debian.
