Reply To: GUI does not work properly



Thanks, Bitahwa. Finaly I moved forward but unfortunately ony half step. Now I started getting data from terminal. The new problem is that data I can see on MessageBox. The next line gives me message:

“An unhandled exception of type ‘System.InvalidOperationException’ occurred in System.Windows.Forms.dll

Additional information: Cross-thread operation not valid: Control ‘rtxtDataArea’ accessed from a thread other than the thread it was created on.”

What are those two different threads?
