Form partially disappers during long processing in a different thread

In my C# WinForm program, I create a new thread to do a long process of
inserting data from Access files to SQL DB. The problem is that some parts
of the MainForm pertially disappear while the new thread is doing its
task. I found many articles on this on the Internet and followed the
example from http://www.codeproject.com/csharp/workerthread.asp. Still
some parts of the MainForm (buttons) disappear and it appears that the
code is not updating the label on the MainForm properly. Are there any
areas that I might be overlooking?

The code looks like this, although this partial code may not make much
sense..

mainForm.BeginI nvoke(mainForm. delegateUpdateM ainUi, new Object[] {"Number
of records inserted: " + numberOfRecords Processed.ToStr ing()} );

Thanks,
TomTom

Hi,

Are you updating the UI frmo the worker thread?
If so use Control.Invoke ( do a search in the archives by Control.Invoke )
and you will find a lot of code snipets that works.

IF you create a new thread the UI should work fine, unless you are
interacting with the UI frmo the worker thread.

Cheers,
