sendkeys

I'm using the sendkeys function that was suggested
here, what happens is that when I send a keystroke
and the menu opens, my other procedures stop working,
al least until I close the menu. I want to send a keystroke
and open the menu, do a pause for a set time, then move
down the menu--this is for a demo and it has to be native
to the program. How do I get around delphi not running my
routines with the menu open? Any suggestions would be
welcome.

Assuming you are using Delphi 2.0/3.0: Put the routine that
sends keys into its own thread. That way, it is (at least moderately) independent from the rest of the program being busy.

If you are using Delphi 1.0, please rate this an F :)

To create a good-looking demo, use the WH_JOURNALRECORD and WH_JOURNALPLAYBACK hooks. (Look up SetWindowsHookEx) These allows you to record mouse movements/clicks and keypresses, and to play them back exactly as entered. The mouse and the keyboard will also be disabled while playing back.

It is a bit of work to code this, but it makes great demos of your apps. Works for both 16 and 32-bit windows.

Regards,

Erik.

Thanks, but unfortunately I am using 1.0. The demo needs
to run on cheesy systems.

Teixiera and Pacheco's _Delphi Developer's Guide_ has a very nice implementation of a SendKeys() function.  The two editions of the book contain versions for Win16 and Win32.  This function alone is almost worth the price of the book; considering how great it is otherwise (I'd rate it as the TOP general Delphi programming book), it's a bargain.

any idea why procedrues stop executing when the menu is opened?

sendkey (vk_menu)
   pause a sec
    stops here and doesnt come back
sendkey(vk_down)

where as taking out the pause and stuff in between it will work
but too fast to follow.

The problem isnt in the pause either.

Oh, I've seen the book, now I have an excuse to buy it.
thanks
