Hey, im having a little problem with my code, ill do my best to explain. I have this virtual function OnConnectionLost() in my networking class, that contain this line of code:

 

// Add a string of text to a listbox

SendMessage(hListBox, LB_ADDSTRING, 0, (LPARAM)(LPCTSTR)"Connection Lost.");

 

 

... And of course it work well when im using the single threaded version of my class.

 

However, when im calling it from a 2nd thread, i got a deadlock, because the main thread is blocked waiting for the 2nd thread to finish(why the main thread is blocked

is not important, but it always is when the code reach OnConnectionLost() in the 2nd thread). So, calling sendmessage block the 2nd thread, and both threads wait for each other.

 

My first though was to use PostMessage(), but it don't work with strings (i even tried passing a static string, to no avail).

 

Sooo, i don't know how to solve that. I could live with commenting this particular function, everything work just fine that way.

But if anyone know how that could be solve, that would be great.

 

Thx.
