本文实例讲述了C++实现显示MP3文件信息的方法。分享给大家供大家参考。具体实现方法如下：

/** * This is small example how to use libZPlay library to play files. * This example is using OpenFile functions to open disk files and play. */#define WIN32_LEAN_AND_MEAN#include <windows.h>#include <olectl.h>#include <ole2.h>#include <stdio.h>#include <stdlib.h>#include <string.h>#include <conio.h>#include <dos.h>#include <conio.h>#include "../include/libzplay.h"using namespace libZPlay;ZPlay* player;int __stdcall CallbackFunc(void* instance, void *user_data, TCallbackMessage message, unsigned int param1, unsigned int param2);int main(int argc, char **argv){ // clear screen system("CLS"); // create class instance player = CreateZPlay(); // chek if we have class instance if(player == 0) { printf("Error: Can't create class instance !nPress key to exit.n"); getch(); return 0; } // get library version int ver = player->GetVersion(); // check if we have version 2.00 and above if(ver < 200) { printf("Error: Need library version 2.00 and above !nPress key to exit.\r\n"); getch(); player->Release(); return 0; } // display version info printf("libZPlay v.%i.%02i\r\n\r\n", ver / 100, ver % 100); if(argc > 1) { TID3InfoEx id3_info; if(player->LoadFileID3Ex(argv[1], sfAutodetect, &id3_info, 1)) // loading ID3v2 { printf("Title: %s\r\n", id3_info.Title); printf("Artist: %s\r\n", id3_info.Artist); printf("Album: %s\r\n", id3_info.Album); printf("Year: %s\r\n", id3_info.Year); printf("Comment: %s\r\n", id3_info.Comment); printf("Genre: %s\r\n", id3_info.Genre); printf("Track: %s\r\n\r\n", id3_info.TrackNum); printf("Artist1 : %s\r\n", id3_info.AlbumArtist ); printf("Composer: %s\r\n", id3_info.Composer ); printf("Original: %s\r\n", id3_info.OriginalArtist ); printf("Copyright: %s\r\n", id3_info.Copyright ); printf("URL: %s\r\n", id3_info.URL ); printf("Encoder: %s\r\n", id3_info.Encoder ); printf("Publisher: %s\r\n", id3_info.Publisher ); printf("BPM: %u\r\n", id3_info.BPM); printf("MIME: %s\r\n", id3_info.Picture.MIMEType); printf("TYPE: %u\r\n", id3_info.Picture.PictureType); printf("Desc: %s\r\n", id3_info.Picture.Description); printf("Size: %u\r\n", id3_info.Picture.PictureDataSize); // draw picture on desktop window player->DrawBitmapToHWND(NULL, 0, 0, 0, 0, id3_info.Picture.hBitmap); } else { printf("No ID3 data\r\n\r\n"); } } else { // no filename in argument player->Release(); // delete ZPlay class char *end = strrchr(argv[0], '\'); if(end && *(end + 1) != 0) end++; else end = argv[0]; printf("Usage: %s filename\r\n\r\nPress key to exit\r\n", end); getch(); return 0; } getch();}

希望本文所述对大家的C++程序设计有所帮助。
