c# - can't start winForm from a thread

I am trying to start a winForm from a thread, but when i do so, the form show but none of the labels are loaded ( the background where they should be is white ) and the form is frozen.

I've tried it with some other winForms that i know that work just fine and it still doesn't seem to work ? Has anyone encountered this problem ?

I know the question is vague but there isn't really any specific code that I could give to help understand the problem.

See Question&Answers more detail:os

That is because the Message Loop runs on UI thread only. And when a control or window is created in any other thread, it cannot access that message loop. And thus, cannot process user input.

To solve this, try creating a window from UI thread and create a thread from that window to do whatever you want to do in different thread.
