If I open an Excel file through PB 12.5 classic using the ShellExcuteW API it opens the file correctly.

I type or change something in the file and close it without saving.  Excel does not detect a change and ask if I want to save.

If I open the same file using Excel directly and make a change and try to close, it does detect the change and ask if I want to save.

Is this normal behavior for ShellExecuteW or is there something else I need to do.

Thanks

Dave V.

Excel is Office 2016 and running on Windows 7 64 bit.

Hi Dave;

   Can you post your PowerScript logic around the ShellExecuteW API command that you are using?

It's got something to do with the way I am using OLE...script attached.  Maybe not closing correctly...



Basically I am opening a spreadsheet, running a macro then deleting the macro and savas as... hope this is almost clear as mud..



 



IF FileExists(ls_excl_sheet) and FileExists(ls_file) then

 IF ole_object.ConnectToNewObject("excel.application") = 0 THEN

   ole_object.Application.DisplayAlerts = "False"

   ole_object.workbooks.Open(ls_excl_sheet) //Open the excel file

 Else

   MessageBox('OLE Error','Unable to start an OLE server process!',Exclamation!)

 END IF

 

 ole_object.Application.Run("GetFileData", ls_file)

 ole_object.Application.workbooks(1).RefreshAll

     ole_object.Application.workbooks(1).Connections("sched_view").Delete

     ole_object.ActiveWorkbook.SaveAs(ls_existing_file,51)  //xlOpenXMLWorkbook

 ole_object.Activeworkbook.close() 

  ole_object.Application.Quit()

 ole_object.DisconnectObject()

 DESTROY ole_object

 

 //remove data file

 FileDelete(ls_file)

 ls_file = ''

 

 //gnv_app.ShellExecuteW ( handle( this ), "open", ls_existing_file, ls_file, ls_Null, 1)

  gnv_app.ShellExecuteW ( handle( this ), "edit", ls_existing_file, ls_file, ls_Null, 1)

Chris, I was able to get it to work... for some reason all I had to do was put the shellexecute into a func/event and call it.  I am guessing it maybe some timing issue, but it now works....

I eventually got it to work, I ended up creating a function and put the API call in it.  I then just called the function and for some reason it worked.  I can only guess that it may have been some sort of timing issue between closing the OLE and calling Exel to open the same file.
