I'm trying to make a window for a Tetris Clone, and I keep getting these 3 errors about an illegal conversion. But I got everything from a Tutorial from this website, but everyone else who has used this says it compiles just fine. Can someone explain these errors? My code is provided after the errors. 1>c:\users\user\documents\visual studio 2008\projects\blocks\blocks\main.cpp(185) : error C2440: '=' : cannot convert from 'const char [10]' to 'LPCWSTR' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\users\user\documents\visual studio 2008\projects\blocks\blocks\main.cpp(194) : error C2664: 'CreateWindowExW' : cannot convert parameter 2 from 'const char [10]' to 'LPCWSTR' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\users\user\documents\visual studio 2008\projects\blocks\blocks\main.cpp(249) : error C2664: 'BitMapObject::Load' : cannot convert parameter 2 from 'const char [11]' to 'LPCTSTR' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd) { // Assign instance to global variable hInstMain = hInstance; // Create window class WNDCLASSEX wcx; // Set the size of the structure wcx.cbSize = sizeof(WNDCLASSEX); // Class style wcx.style = CS_OWNDC | CS_HREDRAW | CS_VREDRAW | CS_DBLCLKS; // Window Procedure wcx.lpfnWndProc = TheWindowProc; // Class Extra wcx.cbClsExtra = 0; // Window Extra wcx.cbWndExtra = 0; // Application Handle wcx.hInstance = hInstMain; // Icon wcx.hIcon = LoadIcon(NULL, IDI_APPLICATION); // Cursor wcx.hCursor = LoadCursor (NULL, IDC_ARROW); // Background Color wcx.hbrBackground = (HBRUSH)GetStockObject(BLACK_BRUSH); // Menu wcx.lpszMenuName = NULL; // Class Name wcx.lpszClassName = WINDOWCLASS; // Small Icon wcx.hIconSm = NULL; // Register the Window Class, return 0 if not successful if(!RegisterClassEx(&wcx)) return(0); // Create Main Window hWndMain = CreateWindowEx(0, WINDOWCLASS, WINDOWTITLE, WS_BORDER | WS_SYSMENU | WS_CAPTION | WS_VISIBLE, 0 , 0, 320, 240, NULL, NULL, hInstMain, NULL); // Error Check if (!hWndMain) return (0); // if program initialization failed, then return with 0 if (!GameInit()) return (0); // Message structure MSG msg; // Message pump for( ; ; ) { // Look for a message if (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE)) { // There is a message // Check that we aren't quitting if (msg.message == WM_QUIT) break; // Translate Message TranslateMessage(&msg); // Dispatch Message DispatchMessage (&msg); } // Run Main Game Loop GameLoop(); } // Clean up program data GameDone(); // return the wParam from the WM_QUIT message return (msg.wParam); } bool GameInit() { // Set the client area size RECT rcTemp; SetRect (&rcTemp, 0, 0, MAPWIDTH*TILESIZE+TILESIZE*GREY, MAPHEIGHT*TILESIZE); // 160x480 client area AdjustWindowRect(&rcTemp, WS_BORDER | WS_SYSMENU | WS_CAPTION | WS_VISIBLE, FALSE); // Adjust the window size based on desired client area SetWindowPos(hWndMain, NULL, 0, 0, rcTemp.right-rcTemp.left, rcTemp.bottom-rcTemp.top, SWP_NOMOVE); // Set the Window width and height // Create map image HDC hdc = GetDC(hWndMain); bmoMap.Create(hdc, MAPWIDTH*TILESIZE+TILESIZE*GREY, MAPHEIGHT*TILESIZE); FillRect (bmoMap, &rcTemp, (HBRUSH) GetStockObject (BLACK_BRUSH)); ReleaseDC (hWndMain, hdc); bmoBlocks.Load(NULL, "blocks.bmp"); NewGame(); return (true); // return success }

Thanks so much for the help. I thought it was something like that causing the error when I read that the tutorial was posted in 2006. Thanks for the link as well. I'm glad to know I found a website, where I can get the help I need.

Now its giving me a linking error, is this a setting as well or just something I should try to figure out myself? I don't want to just keep bothering people with my coding problems if its just me messing up.

Ok, How do I go about adding the source tags to my posts? Thanks again for the help. The code compiled just fine.... finally! :)
