Sticky dialog

I have a dialog with a button, when it is clicked, it will display another dialog that is moved around when the mouse cursor moves. I right-click to pick a "Close" menu item I added in the context menu but this dialog doesn't go away.

in the windowproc I do this

case ID_APP_CLOSE:
{
this->PostMessageW(WM_CLOSE);
}

I change WM_CLOSE into WM_DESTROY, it still there at the mouse cursor, also I am quite sure this line of code has been processed though

Thanks

Been whole day without a reply !

Did you try EndDialog()

Not yet, but I will, yes will :D
