[comp.windows.ms] Sending messages to another app's dialog box.

carlc@mars.SanDiego.NCR.COM (Carl Christofferson) (12/14/89)

I am working on a Windows program in which I need to send a user defined 
message from one application to a modal dialog box in another application.
I can use SendMessage(...) to send a message that contains the handle of the
dialog box to the "plain" application, but I am having trouble receiving a
message back in the dialog box procedure.  Is this even possible?  There are
times when I have a layer of up to 5 modal dialog boxes and I need to 
receive a message in the top dialog box that my file is ready for reading.
Any help would be greatly appreciated! 

Thanks in advance for the info!
