Sample with a main dialog and two additional dialogs. Notice under PBMain that each dialog ends w/%HWND_DESKTOP. The below code copied unmodified from the IDE.

Mark,

Suppose you could post this with code tags? It sure makes it easier to read and easier to copy/paste.

Notice under PBMain that each dialog ends w/%HWND_DESKTOP. The below code copied unmodified from the IDE.

And?

I am not a PB/Forms user, but I very much doubt the generated source code file is created 'Read-only.'
