Hi everyone
I've read many post looking for my answer, but all are similar to this:
http://stackoverflow.com/questions/1610743/reading-excel-files-in-vb-net-leaves-excel-process-hanging
My problem is that I don't quit the app...
The idea is this:
If a User has Excel Open, if he has the file I'm interested in open... get that Excel instance and do whatever I want to do...
But I don't to close his File after I'm done... I want him to keep working on it, the problem is that when he closes Excel... The process keeps running... and running... and running after the user closes Excel with the X button...
this is how I try to do it
This piece is used to know if he has Excel open, and in the For I check for the file name I'm interested in.
Try
oApp = GetObject(, "Excel.Application")
libroAbierto = True
For Each libro As Microsoft.Office.Interop.Excel.Workbook In oApp.Workbooks
If libro.Name = EquipoASeccionIdSeccion.Text & ".xlsm" Then
Exit Try
End If
Next
libroAbierto = False
Catch ex As Exception
oApp = New Microsoft.Office.Interop.Excel.Application
End Try
here would be my code... if he hasn't Excel open, I create a new instance, open the file and everything else.
My code ends with this:
If Not libroAbierto Then
libroSeccion.Close(SaveChanges:=True)
oApp.Quit()
Else
oApp.UserControl = True
libroSeccion.Save()
End If
System.Runtime.InteropServices.Marshal.FinalReleaseComObject(libroOriginal)
System.Runtime.InteropServices.Marshal.FinalReleaseComObject(libroSeccion)
System.Runtime.InteropServices.Marshal.FinalReleaseComObject(origen)
System.Runtime.InteropServices.Marshal.FinalReleaseComObject(copiada)
System.Runtime.InteropServices.Marshal.FinalReleaseComObject(oApp)
libroOriginal = Nothing
libroSeccion = Nothing
oApp = Nothing
origen = Nothing
copiada = Nothing
nuevosGuardados = True
So you can see that, if I opened the file, I call oApp.Quit() and everything else and the Excel Process ends after a few seconds (maybe 5 aprox.)
BUT if I mean the user to keep the file open (not calling Quit()), Excel process keeps running after the user closes Excel with the X button.
Is there any way to do what I try to do?? Control a open instance of excel and releasing everything so when the user closes it with the X button, the Excel Process dies normally???
Thanks!!!
