想弹出对话框 可以多选,MP3文件 用下列代码,编译可以通过,但是点击按钮就出现停止工作(win7)
char szfile[256]="\0"; //文件
char szfilename[256]="\0"; //file name
char szfilter[]= "MP3(*.MP3)\0*.MP3\0"; //文件过滤
char sztitle[]="打开MP3文件"; //过滤器名称
OPENFILENAME lpofn;
lpofn.lStructSize=sizeof(OPENFILENAME);
lpofn.hwndOwner=hwnd;
// lpofn.hInstance=
lpofn.lpstrFilter=szfilter;
lpofn.lpstrCustomFilter=NULL;
//lpofn.nMaxCustFilter
lpofn.nFilterIndex=0;
lpofn.lpstrFile=szfile;
lpofn.nMaxFile=sizeof(szfile);
lpofn.lpstrFile=szfilename;
lpofn.nMaxFileTitle=sizeof(szfilename);
lpofn.lpstrInitialDir=NULL;
lpofn.lpstrTitle=sztitle;
lpofn.Flags=OFN_ALLOWMULTISELECT;
// lpofn.nFileOffset=0;
// lpofn.nFileExtension=0;
// lpofn.lpstrDefExt=0;
// lpofn.lCustData=0;
GetOpenFileName(&lpofn);
char szfile[256]="\0"; //文件
char szfilename[256]="\0"; //file name
char szfilter[]= "MP3(*.MP3)\0*.MP3\0"; //文件过滤
char sztitle[]="打开MP3文件"; //过滤器名称
OPENFILENAME lpofn;
lpofn.lStructSize=sizeof(OPENFILENAME);
lpofn.hwndOwner=hwnd;
// lpofn.hInstance=
lpofn.lpstrFilter=szfilter;
lpofn.lpstrCustomFilter=NULL;
//lpofn.nMaxCustFilter
lpofn.nFilterIndex=0;
lpofn.lpstrFile=szfile;
lpofn.nMaxFile=sizeof(szfile);
lpofn.lpstrFile=szfilename;
lpofn.nMaxFileTitle=sizeof(szfilename);
lpofn.lpstrInitialDir=NULL;
lpofn.lpstrTitle=sztitle;
lpofn.Flags=OFN_ALLOWMULTISELECT;
// lpofn.nFileOffset=0;
// lpofn.nFileExtension=0;
// lpofn.lpstrDefExt=0;
// lpofn.lCustData=0;
GetOpenFileName(&lpofn);
memset(&lpofn, 0, sizeof(OPENFILENAME));另外,lpstrFile要足够大,因为多选时选中的所有文件的路径都在这块内存中(以\0或空格分隔),256太小了。还有,你给lpofn.lpstrFile赋值了两次,给lpstrFileTitle没赋值,但nMaxFileTitle不为0(崩溃应该就是因为这里)。
lpofn.lpstrFile=szfile;
lpofn.nMaxFile=sizeof(szfile);
lpofn.lpstrFile=szfilename;
char szFile[260]; // buffer for file name
HWND hwnd; // owner window
HANDLE hf; // file handle// Initialize OPENFILENAME
ZeroMemory(&ofn, sizeof(ofn));
ofn.lStructSize = sizeof(ofn);
ofn.hwndOwner = hwnd;
ofn.lpstrFile = szFile;
//
// Set lpstrFile[0] to '\0' so that GetOpenFileName does not
// use the contents of szFile to initialize itself.
//
ofn.lpstrFile[0] = '\0';
ofn.nMaxFile = sizeof(szFile);
ofn.lpstrFilter = "All\0*.*\0Text\0*.TXT\0";
ofn.nFilterIndex = 1;
ofn.lpstrFileTitle = NULL;
ofn.nMaxFileTitle = 0;
ofn.lpstrInitialDir = NULL;
ofn.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST;// Display the Open dialog box. if (GetOpenFileName(&ofn)==TRUE)
hf = CreateFile(ofn.lpstrFile, GENERIC_READ,
0, (LPSECURITY_ATTRIBUTES) NULL,
OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL,
(HANDLE) NULL);
lpofn.nMaxFileTitle=sizeof(szfilename);
sizeof用法有问题吧?
lpofn.nMaxFile=256;
lpofn.nMaxFileTitle=256;
