We need the first program to go into the second and push button1

[Cleofas]

There are two programs, both written on delphi. We need the first program to go into the second and push it. button1♪

That's how the program works.

ShellExecute(handle,'open','Test.exe',nil,nil,SW_SHOW);

And how do I push the button? button1

If there's a code.

[Avante]

If you can correct both programmes, it can be done so that the first programme, in a separate flow, expects some event that will send another annex to it, where the first annex would press the button. Such interactions can be organized, for example, by means of music, cell phones or other technology (see inter-process interaction).

If you need a result, not a text of the programme, you can use a ready-to-date software to automate the button, for example, http://www.sikuli.org/ ♪
