Need to send a pasting command from one program to another?

I am using one program to monito开发者_如何学编程r the keyboard for input but would like to use that same program to populate the clipboard then automatically paste to the cursor location of the other program? Can this be done... I am using Delphi 4 Pro.

It's possible, but this is very poor design. The clipboard is provided for the benefit and use of the user, not the programmer. You will end up trashing pre-existing clipboard data. It is not possible to 100% faithfully and reliably cache the clipboard contents and restore it later. That said, you can send Ctrl+V keystrokes or WM_Paste messages to the other window.

Send the target window a wm_Paste message.

But only put data on the clipboard if the user has told you to. The clipboard is something that should always be under control of the user, or else you run the risk of clobbering other data the user was already storing there.
