      If the target window is active, you can use SendInput().

                  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 ?

                        What does SendMessage() return?
