Alternative to Sleep?

[zach campbell]

I have a powerpoint presentation that opens via visual basic 6 as shown below. It runs for 236 minutes then closes. Then the program restarts it with updated information that is also in the code, but not included here. My problem is I have a stop command button to stop the timer and stop everything. However, since I used the sleep function below, it freezes the program if I try to access it. Is there an alternative to using the sleep function as shown below? I am used to the newer visual basic so vb6 is outdated for me. Can you provide example and include it in the code below? Thanks...

Part when it opens powerpoint and runs slide show...

SPresentationFile = "I:\ISO Documents\QA\SPC Graphs\SPC Presentation.ppt"
Set oPPTApp = New PowerPoint.Application
oPPTApp.Visible = True
Set oPPTPres = oPPTApp.Presentations.Open(SPresentationFile)
oPPTPres.SlideShowSettings.Run
Sleep 140000000
oPPTPres.Close
oPPTApp.Quit
Set oPPTApp = Nothing
Set oPPTPres = Nothing
End Sub.


I thought about doing this but it doesn't seem to work... does anyone have any ideas?


SPresentationFile = "I:\ISO Documents\QA\SPC Graphs\SPC Presentation.ppt"
Set oPPTApp = New PowerPoint.Application
oPPTApp.Visible = True
Set oPPTPres = oPPTApp.Presentations.Open(SPresentationFile)
oPPTPres.SlideShowSettings.Run
If Minutes = 236 Then
oPPTPres.Close
oPPTApp.Quit
Set oPPTApp = Nothing
Set oPPTPres = Nothing
End If
End Sub.
