asked on
controlling other application from Delphi
Hi guys!
Is there a way to control another application using Delphi?
In fact, my problem is this one: I have a commercial application that has some nasty limitations. This a very special purpose database. So this application let me print any data record, but only one at a time. I want to write a program in delphi that sends to the proper menu the mouse clicks (or the hot keys associated) to that application so I can print all the records I need without having to go to each menu each time.
Any ideas?
best regards,
Manuel Lopez (lopem)

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
I think to send a hotkey you need to use the VK_MENU + virtual key (maybe something like this VK_MENU + VK_A)
