ok so I have this code Code: #include <windows.h> #include <winuser.h> #include <iomanip> #include <iostream> LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) { switch(msg) { case WM_LBUTTONDOWN: SetWindowText(hwndStatic, "You clicked the left mouse button!"); break; case WM_RBUTTONDOWN: SetWindowText(hwndStatic, "You clicked the right mouse button!"); break; } return 0; } And I get these errors: In function 'LRESULT WndProc(HWND_*,UINT,WPARAM,LPARAM)': 'hwndStatic' undeclared (first use this function) (Each undeclared identifier is reported only once for each function it appears in.)
Thanks I fixed it...The code that i have now changes the title when I click a mouse button...how can I make it send info to notepad...for example, if i click on the right button it will send a 1 to notepad or if i click on left button it will send a 2? Code: #include <windows.h> #include <winuser.h> #include <iomanip> #include <iostream> const char g_szClassName[] = "myWindowClass"; // Step 4: the Window Procedure LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) { switch(msg) { case WM_LBUTTONDOWN: SetWindowText(hwnd, "You clicked the left mouse button!"); break; case WM_RBUTTONDOWN: SetWindowText(hwnd, "You clicked the right mouse button!"); break; case WM_CLOSE: DestroyWindow(hwnd); break; case WM_DESTROY: PostQuitMessage(0); break; default: return DefWindowProc(hwnd, msg, wParam, lParam); } return 0; } int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { WNDCLASSEX wc; HWND hwnd; MSG Msg; //Step 1: Registering the Window Class wc.cbSize = sizeof(WNDCLASSEX); wc.style = 0; wc.lpfnWndProc = WndProc; wc.cbClsExtra = 0; wc.cbWndExtra = 0; wc.hInstance = hInstance; wc.hIcon = LoadIcon(NULL, IDI_APPLICATION); wc.hCursor = LoadCursor(NULL, IDC_ARROW); wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1); wc.lpszMenuName = NULL; wc.lpszClassName = g_szClassName; wc.hIconSm = LoadIcon(NULL, IDI_APPLICATION); if(!RegisterClassEx(&wc)) { MessageBox(NULL, "Window Registration Failed!", "Error!", MB_ICONEXCLAMATION | MB_OK); return 0; } // Step 2: Creating the Window hwnd = CreateWindowEx( WS_EX_CLIENTEDGE, g_szClassName, "The title of my window", WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, 240, 120, NULL, NULL, hInstance, NULL); if(hwnd == NULL) { MessageBox(NULL, "Window Creation Failed!", "Error!", MB_ICONEXCLAMATION | MB_OK); return 0; } ShowWindow(hwnd, nCmdShow); UpdateWindow(hwnd); // Step 3: The Message Loop while(GetMessage(&Msg, NULL, 0, 0) > 0) { TranslateMessage(&Msg); DispatchMessage(&Msg); } return Msg.wParam; }
