Lets say I would want to make a program which types "abc" into a notepad.

hwnd is the handle.

How would I go about using SendMessage or PostMessage to input abc into notepad?


Thanks,
intheomg

you don't send the message to the main notepad window, you send it to the edit child control of the window (using FindWindowEx)

also WM_CHAR

not going to write code because this has been answered many times before and you should be able to find it in a search (if search actually worked)

Well, I still don't really understand SendMessage/PostMessage. Is there any other way to send keys to a MINIMIZED window? Confused

P.S. Google sucks Sad

Thanks,
intheomg


EDIT: Ok, ok, can someone just give me the full code to send keys to a minimized application? I will analyse it thoroughly.

*Hope for someone to pass it to me Sad

Code:
#include <windows.h>
#include <iostream>
using namespace std;

int main(){
    int locatewindow,exit;
    HWND hwnd;
    DWORD pid;
    HANDLE phandle;
   
    locatewindow:
    hwnd = FindWindow(NULL,"Untitled - Notepad");
    if(hwnd==0){
                cout << "Failed to locate notepad's window, please open window and press enter to continue." << endl << endl;
                cin.get();
                goto locatewindow;
                }else{
    GetWindowThreadProcessId(hwnd, &pid); // get the pid
    phandle = OpenProcess(PROCESS_ALL_ACCESS, 0, pid); // we need a handle

    system("Title = Notepad");
    cout << "What would you like to do?" << endl;
    cout << "1. Chat." << endl;
    cout << "2. Exit notepad trainer." << endl << endl;
   
   
                                      }
                                     

    cout << "Press F2 to type." << endl;
    cout << "Press F5 to exit the trainer." << endl << endl;
    while(1==1){
    if(GetAsyncKeyState(VK_F2)){
    cout << "F2 Pressed!" << endl;
    PostMessage(hwnd,WM_KEYDOWN,97,0);
    Sleep(10);
    PostMessage(hwnd,WM_CHAR,97,0);
    Sleep(10);
    PostMessage(hwnd,WM_KEYUP,97,0);
    }
    if(GetAsyncKeyState(VK_F5)){
    goto exit;
    }
}
exit:
    return 0;
}


Can someone see what's wrong with this? =\

Help me please...

EDIT: Oops, spotted three useless declaration.

Thanks,

EDIT!!!!:

Wooo, I got it, after modifying alot from your code.

Code:

#include <stdlib.h>
#include <tchar.h>
#include <windef.h>
#include <windows.h>
using namespace std;

int main()
{
   HWND hwnd, hwndchild; int i;
   LPCTSTR msg = _T("penispenispenis");
   
   hwnd = FindWindow(_T("Notepad"), NULL); //Take notes, this works with any document open
   if (hwnd != NULL) {
      hwndchild = FindWindowEx(hwnd, NULL, TEXT("EDIT"), NULL);
      if (hwndchild != NULL) {
         for(i = 0; i < _tcslen(msg); i++) {
            SendMessage(hwndchild, WM_CHAR, msg[i], 0);
         }
         
         return 0;
      }
   }   
     
   return EXIT_FAILURE;
}


Time to analyse! Thanks alot appal ^^ Very Happy



EDITTTTTTTT!!!! ATTENTION!!!

How do I stimulate clicks at a certain co-ordinates with PostMessage/SendMessage, while the targeted window is minimized? Crying or Very sad

I know it is supposed to be filled in lParam, but, lets say I would like the mouse co-ords - x = 40, y = 50,

how do I go about filling it in? What value do I fill in?


And I have no idea what is MSDN.


Thanks!
