Some GUI-Problems in VB.NET

Hi,

!!! Example has changed !!!

I have problems with the attached VB .net application.

I tried to create threadsafe controls for a textbox and a richtextbox.

The example I have added stores the text-information into a buffer, so when the GUI-elements are not visible there is no output into the elements.

When the elements are showed again, the buffer should be flushed into the GUI-elements. The buffer of the richtextcontrol should have a maximum value of storage like textbox - this has to be added.

The problem I have has to do with the thread-safety of my controls. For example when I start up to 10 threads and move the child-form or change the size, the application acts very strange.

Who can help me?

Thanks

Mike
