[Help]Key Press

[kosacid]

is there a function i can hook because i cant get this to work

void KeyPress(string keys)
{
	keybd_event(VK_RETURN,0x9C,0,0);
	keybd_event(VK_RETURN,0x9C,KEYEVENTF_KEYUP,0);
	string::iterator iter;
	for(iter = keys.begin(); iter != keys.end(); iter++)
	{
		keybd_event(VkKeyScan(*iter),0,0,0);
	}
	keybd_event(VK_RETURN,0x9C,0,0);
	keybd_event(VK_RETURN,0x9C,KEYEVENTF_KEYUP,0);
}

if i remove keybd_event(VK_RETURN,0x9C,KEYEVENTF_KEYUP,0);
it works but the last enter key dosent and i also end with stuck keys even when i use
keybd_event(VkKeyScan(*iter),0,0,0);
keybd_event(VkKeyScan(*iter),0,KEYEVENTF_KEYUP,0);

You can use PostMessage function:

PostMessage(hWnd, 0x100, key, 0); // key down
PostMessage(hWnd, 0x101, key, 0); // key up

For example, if you need press "A", you should write:

PostMessage(hWnd, 0x100, 0x41, 0); // A down
PostMessage(hWnd, 0x101, 0x41, 0); // A up

Magic numbers are ugly and error prone. And try to read the docs on the required params next time.

#define KEYUP_FLAGS 0xC0000001
PostMessage(wnd, WM_KEYDOWN, 'A', 0);
PostMessage(wnd, WM_KEYUP,   'A', KEYUP_FLAGS);

See http://www.ownedcore.com/forums/worl...imulation.html ([Diary/Essay/Compendium] Keyboard simulation) on why it won't work.

got both working i wasent giving the the text box enough time to take the input but here both examples

#define KEYUP_FLAGS 0xC0000001
void KeyPress(string keys)
{
	HWND hwnd = FindWindow(NULL,"World of Warcraft");
	PostMessage(hwnd,WM_KEYDOWN,VK_RETURN,0);
	Sleep(30);
	string::iterator iter;
	for(iter = keys.begin(); iter != keys.end(); iter++)
	{
		PostMessage(hwnd,WM_KEYDOWN,VkKeyScan(*iter),0);
	    PostMessage(hwnd,WM_KEYUP,VkKeyScan(*iter),KEYUP_FLAGS);
	}
	Sleep(30);
	PostMessage(hwnd,WM_KEYUP,VK_RETURN,KEYUP_FLAGS);
	PostMessage(hwnd,WM_KEYDOWN,VK_RETURN,0);
	PostMessage(hwnd,WM_KEYUP,VK_RETURN,KEYUP_FLAGS);
}


void KeyPress(string keys)
{
	keybd_event(VK_RETURN,0x9C,0,0);
	keybd_event(VK_RETURN,0x9C,KEYEVENTF_KEYUP,0);
	Sleep(30);
	string::iterator iter;
	for(iter = keys.begin(); iter != keys.end(); iter++)
	{
		keybd_event(VkKeyScan(*iter),0,0,0);
		keybd_event(VkKeyScan(*iter),0,KEYEVENTF_KEYUP,0);
	}
	Sleep(30);
	keybd_event(VK_RETURN,0x9C,0,0);
	keybd_event(VK_RETURN,0x9C,KEYEVENTF_KEYUP,0);
}

C# but whatever, shows an easy way to do it.

        [DllImport("user32.dll")]
        static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, Int32 wParam, Int32 lParam);

        public static void KeyPress(Keys Key)
        {
            KeyDown(Key);
            KeyUp(Key);
        }

        private static void KeyUp(Keys Key)
        {
            SendMessage(clsMemory.CurrentWindowHandle, (uint)0x101, (int)Key, 0);
            
        }
        private static void KeyDown(Keys Key)
        {
            SendMessage(clsMemory.CurrentWindowHandle, (uint)0x100, (int)Key, 0);
        }

clsMemory.CurrentWindowHandle is just the hWnd of my WoW process, easy enough to find.
