Re: Closing modeless dialogs

My guess is that with PostMessage your string was going out of scope before being used by the window (when message processed). SendMessage() will cause the thread to wait until the message is processed and may not be what you really want. Maybe you could add the string object as a CString to your thread class then it would always be in scope so long as that object exists? You could copy the other string data (from wherever in your thread) to that class member (or members if more than on string needed). What I typically do is create a object for the data I want to pass around and make a new object in the thread that is deleted after being used in the handler. That seems to work pretty well.

PostMessage is robust, up to the issue of message queue saturation (the result of sending

I changed my application that it now uses messages - but SendMessage instead of PostMessage. With PostMessage I could not send strings (I received access violations).

But what about closing the application? Currently I'm using PostMessage(WM_QUIT, ErrorCode, 0); which is quite brute. Before that I tried EndDialog, but this failed when I used a worker thread.
