Displaying a form from thread plz help

Hi,

I ve searched these forums and found other people with simillar problems but havent found a clear solution. Your help would be appreciated...Here is my issues I have a multithreaded application with a dedicated UI thread (my main form) and another thread where i would like to display images completely independent of the UI thread. So i made form class called picForm and use the following code in my other thread:

picForm* newForm = new picForm();
picForm->Show();

The form freezes and doesnt respond. If i put this same code in my UI thread(main form) it does work. So i am thinking it has to do with the fact that I dont have a message pump in the other thread. But how do I create a message pump in the other thread becuase if I use application::run it is a blocking call (leaving that thread useless) and all i wanna do is display an image and forget about it and keep that pic form open until the user wants to close it.

What is the best way to do this ?? Sorry for the long post

thanks

Thanks for the reply I will look into this but really what i am doing is the following:

I wait for some packets in a thread that its not my UI thread.
Once i have al the packets I put them togather and it creates an image.
From this point I would like to display this image. In its own form and not block this thread so I can get more packets.

Right now if i create form .Show() doesnt work it will build in a window but then freeze. If i use showDialog() it will work but I will need to close the window to let the thread continue. I am assuming this happens cuz my other thread does not have a message pump. So i am not sure the best way around this problem...

Thanks
