Exporting multiple objects to multiple Excel sheets

Thu, 30 Mar 2017 18:49:54 GMT

I tried to implement the code from qlikblog_ExportToMultipleExcelSheets.qvw; and couldn't get it to run. I wound up putting in 14 msgbox commands along the entire code until I could get it working by process of elimination. I was able to get it down to where msgbox "2" was. When I run the macro, it works perfectly if I leave msgbox "2" in the code, and press OK when the box comes up. But when I comment out msgbox "2", the code breaks and the macro fails. It just stops and opens the module window.

Can anyone see a reason why this would be occurring where the msgbox command is? Unfortunately due to confidentiality of data, I cannot attach the file.

sub exportToExcel_Variant2

'// Array for export definitions
Dim aryExport(5,3)

aryExport(0,0) = "objRanking"

You should continue to add msgboxs until you can identify the exact line where the macro fails.

Thanks, I already did that. I had 14, this is the only one left. This is where it fails.

So you are saying that:

Set objExcelDoc = objExcelApp.Workbooks.Add

is the line that fails?

This code works fine for me:

sub test

Set objExcelApp = CreateObject("Excel.Application")

objExcelApp.Visible = true 'false if you want to hide Excel

objExcelApp.DisplayAlerts = false

Set objExcelDoc = objExcelApp.Workbooks.Add

end sub

I guess I'm really not sure then. If I put another msgbox after it and comment out msgbox 2, then it fails. I'm at a loss how else to troubleshoot.

When you run the code and it fails, do you have an instance of Excel that was opened by the code?

It appears that when I comment out the msgbox and run it, the screen flickers like it was trying to open Excel, then the module window opens and the code stops running.

You might look in the task manager to see if you have multiple instances of Excel open. If so, end those processes.

When you run the code up to msgbox "2" , you should have an open instance of Excel with no open workbook.

You should try to debug just this code snippet:

sub test

Set objExcelApp = CreateObject("Excel.Application")

objExcelApp.Visible = true 'false if you want to hide Excel

objExcelApp.DisplayAlerts = false

Set objExcelDoc = objExcelApp.Workbooks.Add

end sub

Thank you. I had tried something yesterday because I felt that if the code ran when the msgbox was there, then it should run without. I wondered if there was a timing issue. So I scripted in this delay and it runs perfectly now. Thanks again for helping me pin-point the code snipet. This is was what finally worked.

sub test

Set objExcelApp = CreateObject("Excel.Application")
objExcelApp.Visible = true 'false if you want to hide Excel
objExcelApp.DisplayAlerts = false

Dim dteWait
dteWait = DateAdd("s", 2, Now())
Do Until (Now() > dteWait)
Loop

Set objExcelDoc = objExcelApp.Workbooks.Add

end sub
