postmessage in an exe

after i us开发者_JS百科e process.start() a form1 appears on the desktop. When i click the form2 button from form1 a new form appears. how can i postmessage in form2? can someone please give me an example? I think i need to use FindWindow, but i don't know what to write as parameters. thx

Questions:

1. is there a way i can search in my application the elements from the form1 list (which appears after i run process.start in my app) and print them?
2. is there a way i can double click programatically an element from form1 - which automatically generates form2?
3. is there a way to postmessage in form2? thx

i am using user32.dll
