For anyone interested, here is the result of my two previous threads about resizing modal dialogs, and how to get keypress keys using GetUserEvent.
The intent was to recreate the four CVI Message/Prompt popups, designing them to adapt to the color scheme of the calling application. The result is four functions which do this. The attached project demonstrates these new functions. Before I'm done with this, I'll put the functions in a function tree and document them. I welcome comments.
