initializing 8.0 (newbie question) Direct3D

dalaptop · 2001-11-09T15:14:49

I have recently been starting to learn DirectX 8.0. I have read the DirectX 8.0 SDK documentation from microsoft and I have followed along with the first tutorial and written the following sample to see I could use DirectX Graphics or more specifically Direct3D. This code compiles but nothing shows up on the screen. It''s as if nothing happened. I have to ALT-CTRL-DEL it and End it''s task. Please help me to find out what''s wrong with the following code: #include #include HINSTANCE hinst; HWND hwnd; LPDIRECT3D8 d3d = NULL; D3DDISPLAYMODE d3ddm; D3DPRESENT_PARAMETERS d3dpp; LPDIRECT3DDEVICE8 d3dd = NULL; void InitD3D(); void Render(); void Cleanup(); LRESULT WINAPI WinProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam); int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE, LPSTR, int) { WNDCLASSEX wc; MSG msg; hinst = hInstance; wc.cbSize = sizeof(WNDCLASSEX); wc.lpfnWndProc = WinProc; wc.hInstance = hinst; wc.style = CS_DBLCLKS|CS_OWNDC|CS_HREDRAW|CS_VREDRAW; wc.cbClsExtra = 0; wc.cbWndExtra = 0; wc.hIcon = LoadIcon(NULL, IDI_APPLICATION); wc.hCursor = LoadCursor(NULL, IDC_ARROW); wc.hbrBackground = (HBRUSH) GetStockObject(BLACK_BRUSH); wc.lpszMenuName = NULL; wc.lpszClassName = "DirectX"; wc.hIconSm = LoadIcon(NULL, IDI_APPLICATION); RegisterClassEx(&wc); hwnd = CreateWindowEx(NULL, NULL, "Dx8", WS_OVERLAPPEDWINDOW, 25, 25, 100, 100, GetDesktopWindow(), NULL, hinst, NULL); InitD3D(); while (GetMessage(&msg, NULL, 0, 0)) { TranslateMessage(&msg;; DispatchMessage(&msg;; } return msg.wParam; } LRESULT WINAPI WinProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam) { switch(msg) { case WM_DESTROY: Cleanup(); PostQuitMessage(0); return 0; case WM_PAINT: Render(); ValidateRect(hWnd, NULL); return 0; } return DefWindowProc(hWnd, msg, wParam, lParam); } void InitD3D() { d3d = Direct3DCreate8(D3D_SDK_VERSION); d3d->GetAdapterDisplayMode(D3DADAPTER_DEFAULT, &d3ddm); ZeroMemory(&d3dpp, sizeof(d3dpp)); d3dpp.Windowed = TRUE; d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD; d3dpp.BackBufferFormat = d3ddm.Format; d3d->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hwnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dpp, &d3dd); } void Render() { d3dd->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0,0,255), 1.0f, 0); d3dd->BeginScene(); d3dd->EndScene(); d3dd->Present(NULL, NULL, NULL, NULL); } void Cleanup() { if(d3dd != NULL) { d3dd->Release(); d3dd = NULL; } if(d3d != NULL) { d3d->Release(); d3d = NULL; } }

Sorry this is off-topic, but what do you mean by use f10 keystrokes to test?

In VS, if you start your program in debug mode, pressing F10 let''s you "step" through your code as its executing. It''s VERY handy, you can see exactly what your code is doing. I can''t tell you how many times I''ve used the debugger to run down pesky bugs. =)
