 |
|
Hey all,
I know basics in C++ and I'm beginner at win32 programming.
My Questions is, how can I send keys to a Programm that is minimized?
I know how to simulate a letter, so its like I use the Keyboard.
But now I want to send the letters to a Programm, without simulating the Keyboard.So I can do something else in the Time, my Programm is typing a text or something to another Programm.
For example, if some1 could help me making a Program that writes a Text to notebook (from windows), and notebook is minized all the time, I would be very glad.
I hope some1 can help me.

1) Get handle to the window ("HWND")
2) Send the WM_CHAR message to it
Please don't try this on a protected game and say it doesn't work.

| Code: |
#include <windows.h>
#include <stdio.h>
//
//Example of sending a message to notepad.
//
int main(int argc, char * argv[])
{
HWND hNotepad; int i;
char * Message = "Hello, redhead!";
hNotepad = FindWindowEx(FindWindow("Notepad", NULL), 0, "Edit", 0);
if (hNotepad == NULL) {
return 1;
} else {
for (i = 0; i < lstrlen(Message); i++)
SendMessage(hNotepad, WM_CHAR, Message[i], 0);
}
puts("Message Sent.");
getch();
return 0;
}

Thx, works great.
But I've got 2 more Questions.
What do I have to write when I want the program to send "enter" or F1 or something like that.
The 2. Question is, is there a way to read what is written in the notepad?

You should be able to get the text by getting the edit control's handle using appal's sample code, then sending WM_GETTEXT to the control.
Edit: somehow linking to msdn pages doesn't work, so just google WM_GETTEXT.

So by using this, I could make a keylogger to get my sisters password.
