Closing form kills the app - Visual Basic .NET

John

Hi

I have this problem on winxp/offixexp machine but not on win2k/office2k
machines.

I have a main form which has a panel which has a child form. The child form
opens a dialog form. When the dialog form is closed using the 'x' button or
using me.close in code, the app crashes. The source the error is pointed as
my main app loop; Application.Run (frmMain) in Sub Main.

I am totally baffled by this error. Any ideas to solve this would be
appreciated. I am using vs.net 2003 with framework 1.1.

=============== =============== =============== ===

For those with a stronger heart, here is more information; I used the
Windows Debugging Tools which provided the trace but with added problem that
app crashes earlier during the opening of the child form. Here is the trace
anyhow. Thanks.

How to prevent Access from closing

I have a form which the user must complete before closing. I have disabled the window x button and use my own exit button.

Weird Problem: Closing MDI Parent re-directed to MDI Child

For some reason, when I click the X to close my MDI parent form, the action appears to be re-directed to one of the MDI child forms, and the parent remains open. I am then unable to close the application. What should happen, is that the main MDI form should close, taking the child forms with it. There is code to loop through the child forms, remove the controls on each of them, and then close the form, but this code should execute only...

Does it make sense to put this If e.Cancel Then Exit Sub at the beginning of form closing events so if the user cancels the app's exiting in one Closing routine he will not be asked again by another when its form Closing routine is run?
