How I can get the text of a textbox that is on other app?

[Marco2250]

Hi all. (windows forms). How I can get the text of a textbox that is on other app? Example: I have an app running that has a textbox which Text property is "MICROSOFT VISUAL STUDIO ROCKS!". I want to make an application that will obtain the handle of that textbox and get its contents (its text property value). I already have the code that obtain the handle. I think that I need to use WM_GETTEXT in conjunction with OpenProcess, WriteProcessMemory, SendMessage and ReadProcessMemory. But I have no idea how to do it. Please help me. Thx in advance. Best regards, Marco Alves.
