PlaySound播放音乐
今天测试了一下windows32的PlaySound函数，路径没错，运行也不报错，但是却听不到歌曲的声音，运行的时候听到一声“咚”。加个循环的话就发出“咚咚咚”的响声，求帮忙，其中wav文件是由mp3文件修改后缀而成的，无论是绝对路径还是相对路径，都没有听到音乐的效果，还有一定，PlaySound()写的路径正确与否都不会报错，求帮忙？（论坛已求助，无人问津）代码如下：
#include<windows.h>#pragma comment(lib,"winmm.lib")#include <mmsystem.h>LRESULT CALLBACK WindowProc1( HWND hwnd, // handle to window UINT Msg, // message identifier WPARAM wParam, // first message parameter LPARAM lParam // second message parameter);int WINAPI WinMain( HINSTANCE hInstance, // handle to current instance HINSTANCE hPrevInstance, // handle to previous instance LPSTR lpCmdLine, // command line int nCmdShow // show state ){ static TCHAR szAppName[]=TEXT("HelloWin"); HWND hwnd; MSG msg; WNDCLASS wndclass; wndclass.cbClsExtra=0; wndclass.cbWndExtra=0; wndclass.hbrBackground=(HBRUSH)GetStockObject(WHITE_BRUSH); wndclass.hCursor=LoadCursor(NULL,IDC_ARROW); wndclass.hIcon=LoadIcon(NULL,IDI_ERROR); wndclass.hInstance=hInstance; wndclass.lpfnWndProc= WindowProc1; wndclass.lpszClassName=szAppName; wndclass.lpszMenuName=NULL; wndclass.style=CS_HREDRAW|CS_VREDRAW; if(!RegisterClass(&wndclass)){ MessageBox(NULL,TEXT("This program requires Windows NT!"),szAppName,MB_ICONERROR); return 0; } hwnd=CreateWindow( szAppName, // registered class name TEXT("This is Hello Program"), // window name WS_OVERLAPPEDWINDOW, // window style CW_USEDEFAULT, // horizontal position of window CW_USEDEFAULT, // vertical position of window CW_USEDEFAULT, // window width CW_USEDEFAULT, // window height NULL, // handle to parent or owner window NULL, // menu handle or child identifier hInstance, // handle to application instance NULL // window-creation data); ShowWindow(hwnd,nCmdShow); UpdateWindow(hwnd); while(GetMessage(&msg,NULL,0,0)){ TranslateMessage(&msg); DispatchMessage(&msg); } return msg.wParam;}LRESULT CALLBACK WindowProc1( HWND hwnd, // handle to window UINT Msg, // message identifier WPARAM wParam, // first message parameter LPARAM lParam // second message parameter){ HDC hdc; PAINTSTRUCT ps; RECT rect; switch(Msg){ case WM_CREATE: PlaySound(TEXT("tingge.wav"),NULL,SND_FILENAME|SND_ASYNC); return 0; case WM_PAINT: hdc=BeginPaint(hwnd,&ps); GetClientRect(hwnd,&rect); DrawText(hdc,TEXT("Hello,Window98!"),-1,&rect,DT_CENTER|DT_SINGLELINE|DT_VCENTER); EndPaint(hwnd,&ps); return 0; case WM_DESTROY: PostQuitMessage(0); return 0; } return DefWindowProc(hwnd,Msg,wParam,lParam);}留下你的脚印。。。
此问题完美解决了，wav格式不能直接由mp3格式修改后缀而得，用格式工厂或千千静听可以转成wav(wave)格式，这样就可以解决了。
