求教：GetOpenFileName的使用？
我定义了一个OPENFILENAME结构的对象op，又对其做了初始化，然后这样写：
if(GetOpenFileName(&op)){/*Do Something*/}
为何不能显示“打开”对话框？
如何解决，谢了！

你自己看看吧,这是我写的,运行很正常.
OPENFILENAME ofn ;
TCHAR szFullName[_MAX_PATH];
::ZeroMemory (&ofn, sizeof(OPENFILENAME)) ;
szFullName[0] = TEXT('\0') ;
ofn.lStructSize = sizeof (OPENFILENAME) ;
ofn.hwndOwner = m_hWnd;
ofn.hInstance = NULL ;
ofn.lpstrFilter = szFilter ? szFilter : TEXT("All Files (*.*)\0*.*\0\0") ;
ofn.lpstrCustomFilter = NULL ;
ofn.nMaxCustFilter = 0 ;
ofn.nFilterIndex = 0 ;
ofn.nMaxFile = MAX_PATH ;
ofn.nMaxFileTitle = MAX_PATH ;
ofn.lpstrInitialDir = "c:\\" ;
ofn.lpstrTitle = "另存为";
sprintf(szFullName,m_strPathD);
ofn.lpstrFile = szFullName ;
ofn.nFileExtension = 0 ;
ofn.lpstrDefExt = TEXT("*") ;
ofn.lCustData = 0 ;
ofn.lpfnHook = NULL ;
ofn.lpTemplateName = NULL ;
ofn.Flags = OFN_ENABLESIZING | OFN_OVERWRITEPROMPT ;
if(!::GetSaveFileName (&ofn))
return;
::CopyFile(m_strPathD,ofn.lpstrFile,FALSE);
OPENFILENAME ofn ;
TCHAR szFullName[_MAX_PATH];
::ZeroMemory (&ofn, sizeof(OPENFILENAME)) ;
szFullName[0] = TEXT('\0') ;
ofn.lStructSize = sizeof (OPENFILENAME) ;
ofn.hwndOwner = m_hWnd;
ofn.hInstance = NULL ;
ofn.lpstrFilter = szFilter ? szFilter : TEXT("All Files (*.*)\0*.*\0\0") ;
ofn.lpstrCustomFilter = NULL ;
ofn.nMaxCustFilter = 0 ;
ofn.nFilterIndex = 0 ;

首先把op清零
然后按要求设置以下几个成员的值:
lpstrfile
maxfile(?)
