aIW|SendCommand from external app

Posts 1–15 of 21 · Page 1 of 2

Code:

void WriteCommandToConsole(string Command)
{
    HWND hwnd = FindWindow(NULL,L"aIW Console");
    HWND childHwnd = FindWindowEx(hwnd,NULL,L"Edit",NULL);
    const int Lenght = Command.length();

    char cCommand[Lenght];

    for(int i = 0; i < Command.size();i++)
    {
        cCommand[i] = Command.at(i);
    }

    for(int i = 0,inInt; i < Command.size(); i++)
    {
        inInt = cCommand[i];
        SendMessage(childHwnd,WM_CHAR,inInt,true); 
    }
    SendMessage(childHwnd,WM_CHAR,VK_RETURN,true);

}

Usage:

Code:

WriteCommandToConsole("cg_drawFps 1");

Enjoy

I found out a good type cast so here is a improved version:

Code:

void SendCommand(LPCTSTR Command)
{
    static HWND editBox = FindWindowEx(FindWindow(NULL, L"aIW Console"),0,L"Edit",0);
    if(editBox == NULL)
        return;
    else
    {
        SendMessage(editBox,WM_SETTEXT,0,(LPARAM)((LPCTSTR)Command));
        SendMessage(editBox,WM_CHAR,VK_RETURN,0);
    }
}

amazing, and no need for offsets. +1

Thank you, i am back now

Wow, nice one, definitely some rep + for this.

Question though, why the double for loops? Doesn't this work?

Code:

void WriteCommandToConsole(string Command)
{
    static HWND childHwnd = FindWindowEx(FindWindow(NULL,L"aIW Console"),NULL,L"Edit",NULL);
    short length = Command.length();

    for(short i = 0; i < length; ++i)
    {
        SendMessage(childHwnd,WM_CHAR,(int)Command.at(i),true); 
    }
    SendMessage(childHwnd,WM_CHAR,VK_RETURN,true);

}

Optimizations: Shorts instead of ints as messages are never 2.1 billion in length, changed i++ to ++i to make use of the INC instruction instead of the ADD instruction in assembly, instead of calling command.length() every loop (I learned that it actually checks the length every single loop and ends up slowing down the loops when I was learning PHP), and straight casting into int instead of using a temporary int holder. The handle to Edit is only initialized once as it's static, since the window handle shouldn't change between writes.

@shadowx360 You can use an unsigned short because i is never negative. You should also beware that if you call this function before the console is open, it will not work.

If you want to follow the syntax rules you should use a LPARAM(long)

Code:

void WriteCommandToConsole(string Command)
{
    static HWND childHwnd = FindWindowEx(FindWindow(NULL,L"aIW Console"),NULL,L"Edit",NULL);
    if(childHwnd == NULL)
    {
          childHwnd = FindWindowEx(FindWindow(NULL,L"aIW Console"),NULL,L"Edit",NULL);
          if(childHwnd == NULL)
                 return;
    }
    short length = Command.length();

    for(short i = 0; i < length; ++i)
    {
        SendMessage(childHwnd,WM_CHAR,(int)Command.at(i),true); 
    }
    SendMessage(childHwnd,WM_CHAR,VK_RETURN,true);

}

Fixed issue in case the hwnd is null.

    {
        SendMessage(editBox,WM_SETTEXT,0,(LPARAM)((LPCTSTR)Command));
        SendMessage(editBox,WM_CHAR,VK_RETURN,0);
    }
}
