Application.DoEvents after closing a form

[Steven Nagy]

Hey all,

I have a WinCE app and in it I have a settings form that pops up if a
menu item is pressed.
The problem is that just opening the form and closing it again, as soon
as it hits any sort of refresh command, or Application.DoEvents, it
doesn't go past that line of code.

Here's the actual code. If I put a break point in the
Application.DoEvents lines, it never gets to the NEXT line. I don't
know alot about Compact Framework so perhaps my understanding/usage of
Applciation.DoEvents is wrong. Normally I wouldn't have it at this
point anyway, but its to illustrate that it is definately the DoEvents
call that is stopping my application.

If settingsForm.ShowDialog() = DialogResult.OK Then
Application.DoEvents()
saveSettings()
init()
Else
Application.DoEvents()
End If


Many thanks,
Steven

I don't know of any reason for your code to stop on this call. What version
of VS and the Compact Framework are you using? BTW, why are you calling
Application.DoEvents here? The reason isn't obvious.

There is no reason for it being here.
IT was further in the code, but I put it here straight after the second
form closes to see if it also happens here, which it does.

I have a feeling it might be because of the RFID reader which is
running in another thread.
I''ve completely closed the reader before opening the second (settings)
form. And then restart it again after.
It made no difference though.
It seems completely random.

Its running on 4.2. Using VS2003.
