The language that I'm using is C++.

I have a backgroundworker to prevent my UI from crashing.

However, within the background function I need to update my UI.

I read that using the control's Invoke will do the trick. However, I can't seem to make it work. The code is as follows:
pictureBox2->Invoke((MethodInvoker^) delegate(){
pictureBox2->Image = btmp;
error C2065: 'delegate' : undeclared identifier	
error C2143: syntax error : missing ')' before '{'	
error C2143: syntax error : missing ';' before '{'	
error C2059: syntax error : ')'
Any ideas?

Thanks! Any help would be greatly appreciated!
