Oops. I sure botched that up! I meant to say I'd use FrmDoDialog, instead of
FrmPopupFrom. The former is a blocking API that has it's own event loop (to
which you can add your own bit of code), while the latter is non-blocking,
returning immediately. The advantage of a blocking API is that you can find
out what the user did in the dialog BEFORE it was closed, then update the
form underneath AFTER the dialog has been closed. There are examples of this
technique in the SDK.
