Send message to window
-
I want to send a key to a window. I used Global Hook and my code is like this : //In hook proc : if(nCode <0) CallNextHookEx(MyHook,nCode,wParam,lParam); hWndApp = CWnd::FindWindow(0,_T("Test")); if (hWndApp == NULL) MessageBox(NULL,L" Can't find the window", L"",0); hWndApp->SendMessage(WM_CHAR, 8, 0); //Backspace It can find the window but it can't send the message. Some one plz help me :rose:

If the target window is active, you can use
SendInput()."Love people and use things, not love things and use people." - Unknown

Could you show me an example of using SendInput to send a key to an active window plz ? I find it difficult to find a specific example :(
I found this using Google.

Plz help me one more time. I would like to know how to send WM_KEYUP by SendInput. When I send a key, it seems to be pressed forever ...

I've read many pages from the pages you gave me but I still can't find the answer :( They recommend to use SendMessage but it doesn't work with SendMessage...
Is the problem with sending or receiving? What does your code look like?

This is my code :
HWND windowHandle = ::FindWindow(0, _T("Test"));
INPUT *key;
::SetForegroundWindow(windowHandle);
key = new INPUT;
key->type = INPUT_KEYBOARD;
key->ki.wVk = VK_CONTROL;
key->ki.dwFlags = 0;
key->ki.time = 0;
key->ki.wScan = 0;
key->ki.dwExtraInfo = 0;
SendInput(1,key,sizeof(INPUT));
key->ki.dwExtraInfo = KEYEVENTF_KEYUP;
SendInput(1,key,sizeof(INPUT));::SendMessage(windowHandle,WM_KEYUP,0,0); //==> No effect ?
