How can i make a C++ programm (spammer) without GUI that write an entered text in a textbox and simulate an enter pressure? Please explain everything very exactly and give me a program example.
...leads me to believe you're after a program that spams. If I'm wrong, then I apologise. You should edit your OP to indicate your intent isn't to spam people.
If this is a genuine question geared towards data entry in a Win32 program, then I recommend that your move this question to the Windows Programming forum to the left.
Yea, I did a program like that a while ago, but it just spammed in the terminal window (I'm on a MAC, there's no code for making new windows or anything of the sort in C++. Objective-C, however ...)
