とりあえず使ってみる
ウインドウの作成:win32 の記事で作ったウインドウに、
MCI ウィンドウ をつけてみた。
#include <windows.h> #include <stdlib.h> #include <string.h> #include <tchar.h> #include <vfw.h> #pragma comment (lib, "vfw32.lib") // Global variables // The main window class name. static TCHAR szWindowClass[] = _T("win32app"); // The string that appears in the application's title bar. static TCHAR szTitle[] = _T("Win32 Guided Tour Application"); HINSTANCE hInst; // Forward declarations of functions included in this code module: LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM); int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { WNDCLASSEX wcex; wcex.cbSize = sizeof(WNDCLASSEX); wcex.style = CS_HREDRAW | CS_VREDRAW; wcex.lpfnWndProc = WndProc; wcex.cbClsExtra = 0; wcex.cbWndExtra = 0; wcex.hInstance = hInstance; wcex.hIcon = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_APPLICATION)); wcex.hCursor = LoadCursor(NULL, IDC_ARROW); wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW+1); wcex.lpszMenuName = NULL; wcex.lpszClassName = szWindowClass; wcex.hIconSm = LoadIcon(wcex.hInstance, MAKEINTRESOURCE(IDI_APPLICATION)); if (!RegisterClassEx(&wcex)) { MessageBox(NULL, _T("Call to RegisterClassEx failed!"), _T("Win32 Guided Tour"), NULL); return 1; } hInst = hInstance; // Store instance handle in our global variable // The parameters to CreateWindow explained: // szWindowClass: the name of the application // szTitle: the text that appears in the title bar // WS_OVERLAPPEDWINDOW: the type of window to create // CW_USEDEFAULT, CW_USEDEFAULT: initial position (x, y) // 500, 100: initial size (width, length) // NULL: the parent of this window // NULL: this application does not have a menu bar // hInstance: the first parameter from WinMain // NULL: not used in this application HWND hWnd = CreateWindow( szWindowClass, szTitle, WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, 500, 300, NULL, NULL, hInstance, NULL ); if (!hWnd) { MessageBox(NULL, _T("Call to CreateWindow failed!"), _T("Win32 Guided Tour"), NULL); return 1; } // The parameters to ShowWindow explained: // hWnd: the value returned from CreateWindow // nCmdShow: the fourth parameter from WinMain ShowWindow(hWnd, nCmdShow); UpdateWindow(hWnd); // Main message loop: MSG msg; while (GetMessage(&msg, NULL, 0, 0)) { TranslateMessage(&msg); DispatchMessage(&msg); } return (int) msg.wParam; } // // FUNCTION: WndProc(HWND, UINT, WPARAM, LPARAM) // // PURPOSE: Processes messages for the main window. // // WM_PAINT - Paint the main window // WM_DESTROY - post a quit message and return // // LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) { PAINTSTRUCT ps; HDC hdc; TCHAR greeting[] = _T("Hello, World!"); switch (message) { case WM_CREATE: MCIWndCreate(hWnd, ((LPCREATESTRUCT)lParam)->hInstance, 0, L"E:\\sampleMovie\\sample.avi"); break; case WM_PAINT: hdc = BeginPaint(hWnd, &ps); // Here your application is laid out. // For this introduction, we just print out "Hello, World!" // in the top left corner.

EndPaint(hWnd, &ps); break; case WM_DESTROY: PostQuitMessage(0); break; default: return DefWindowProc(hWnd, message, wParam, lParam); break; } return 0; }
AVIファイルでも再生できるファイルと再生できないファイルがあった。
子ウィンドウの既定のウィンドウスタイルは WS_CHILD、WS_BORDER および WS_VISIBLE です。
WS_MAXIMIZE | WS_VISIBLE | WS_CHILD
