求大神，快被这个问题搞疯了

写了个画板程序，在实现保存功能的时候，要先初始化一个保存对话框，可是每次都是初始化失败无法打开对话框，代码如下，求解啊。

void PopFileInitialize(HWND hWnd)
{
ofn.lStructSize = sizeof (OPENFILENAME) ;
ofn.hwndOwner = hWnd ;
ofn.hInstance = NULL ;
ofn.lpstrFilter = _T("Painter File\0*.mzk\0All Files\0*.*\0\0");
ofn.lpstrCustomFilter = NULL ;
ofn.nMaxCustFilter = 0 ;
ofn.nFilterIndex = 1 ;
ofn.lpstrFile = NULL ;
ofn.nMaxFile = MAX_PATH ;
ofn.lpstrFileTitle = NULL ;
ofn.nMaxFileTitle = MAX_PATH ;
ofn.lpstrInitialDir = NULL ;
ofn.lpstrTitle = NULL ;
ofn.Flags = 0 ;
ofn.nFileOffset = 0 ;
ofn.nFileExtension = 0 ;
ofn.lpstrDefExt = _T ("mzk") ;
ofn.lCustData = 0 ;
ofn.lpfnHook = NULL ;
ofn.lpTemplateName = NULL ;
ofn.dwReserved = 0;
ofn.FlagsEx = 0;
}
//这里是打开对话框
BOOL PopFileSaveDlg (HWND hwnd, PTSTR pstrFileName, PTSTR pstrTitleName)
{
ofn.hwndOwner = hwnd;
ofn.lpstrFile = pstrFileName;
ofn.lpstrFileTitle = pstrTitleName;
ofn.Flags = OFN_CREATEPROMPT | OFN_HIDEREADONLY;

return GetOpenFileName (&ofn);
}
//这个GetOpenFileName 每次都是返回0，我用CommDlgExtendedError函数测试发现返回的错误信息是

“CDERR_STRUCTSIZE：对应的公共对话框初始化结构旧IStructSize成无效成员。”

不知道为什么啊，大家帮帮忙！！

OPENFILENAME ofn = {0};
TCHAR path[MAX_PATH];

ofn.lStructSize = sizeof(ofn);
ofn.hwndOwner = hWnd;
ofn.lpstrFilter = _T("Painter File\0*.mzk\0All Files\0*.*\0\0");
ofn.lpstrFile = path;
ofn.nMaxFile = MAX_PATH;
ofn.Flags = OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT;

if (GetOpenFileName(&ofn))
{
// chosen filename is stored in 'path' now.
}

这是要我在哪里改动呢？

[星羽]

BOOL PopFileSaveDlg (HWND hwnd, PTSTR pstrFileName, PTSTR pstrTitleName)
{
ofn.hwndOwner = hwnd;
ofn.lpstrFile = pstrFileName;
ofn.lpstrFileTitle = pstrTitleName;
ofn.Flags = OFN_CREATEPROMPT | OFN_HIDEREADONLY;

return GetOpenFileName (&ofn);
}

你这个函数里没定义ofn
ofn是全局的
我用的代码试了下，没啥问题啊，先init了然后调用这个函数，

是我忘了先调用PopFileInitialize，看了回复才突然响起来，非常感想！
