In vb.6 that works. But in .net the Object Lifetime is
different. I also tried GC.Collect after the
objExcel.Quit.

after objExcel.Quit I would have

objWorkbook = Nothing
objWorkbooks = Nothing
objExcel = Nothing

or the .Net equivalent.

When I create a Windows Forms Application using
VB.NET2003
and have that application create and save a
workbook, I
cannot open the worksheet with Excel until I close
the
VB
application.

Steps to reproduce the problem.

1 Create a Windows Forms Application.

2 Add a reference to 'Microsoft Excel 9.0 Object
Library'.

3 Add a command button to Form1 (Button1).

4 Add the following code to the form:

'***Begin Code***
Private Sub Button1_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs) Handles
Button1.Click

Dim objExcel As Excel.Application
Dim objWorkbook As Excel.Workbook
Dim objWorkbooks As Excel.Workbooks

objExcel = New Excel.Application
objWorkbooks = objExcel.Workbooks
objWorkbook = objWorkbooks.Add

objWorkbook.SaveAs("C:\TempWorkbook.xls")

objExcel.Quit()

End Sub
'***End Code***

5 Run the program.

6 Click the button 1 time.

7 In windows explorer double click the file
C:\TempWorkbook.xls. At this point Excel opens but
the
grid area does not display correctly.

8 Close excel.

9 Close the VB application by clicking the x button
in
the
corner of form1. If you click 'Stop Debugging' in the
IDE
an Excel process will continue to run in Task
Manager-
Processes Tab. You need to 'End Process' or rebbot to
get
rid of it.

10 In windows explorer double click the file
C:\TempWorkbook.xls. At this point Excel opens the
file
correctly.
