Help with sending keys

Posts 1–5 of 5 · Page 1 of 1

I need help with sending the space key to Combat Arms.

Apparently you can't do VKs anymore since Nexon patched them or something like that. So my bunny hop doesn't work. It's MSVC++ and Windows forms project...

I have tried :
SendKeys::Send();
SendKeys::SendWait();
GenerateKey(); (Person made function)
keybd_event( VK_SPACE, 0x45, KEYEVENTF_EXTENDEDKEY, 0 );
keybd_event( VK_SPACE, 0x45, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, 0 );

etc...
Nothing seems to work. Is there any way I can do this?

You can try PostMessage()

PostMessage Function()

I did a little demo for Notepad for you.

Code:

#include <windows.h>
#include <iostream>

using namespace std;

HWND hwnd;
HWND child;

int main()
{
    hwnd = FindWindow(0,"Untitled - Notepad");
    if(!hwnd)
    {
             return 0;
    }
    child = FindWindowEx(hwnd,0,"edit",0);
    if(!child)
    {
              return 0;
    }
    
    SetForegroundWindow(child);
    Sleep(500);
           
    PostMessage(child,WM_KEYDOWN,(WPARAM)VkKeyScan('w'),0);
    
    cin.get();
}

Pretty much just types W into the edit box on NotePad.

FindWindowEx was just to find the child window, in this case it's the giant edit box where you type. I don't think you need to do that for CA though.

Code:

child = FindWindowEx(hwnd,0,"edit",0);

"edit" is the system class. If you were to make a textbox using windows api, the system class would be "edit", if you were making a button, it would be "button" etc etc..

CreateWindow Function()
