我有用VC ++开发的Windows应用程序。我正在使用CFileDialog显示对话框。但是，当我右键单击对话框时，它崩溃了。相同的代码在XP中可以正常工作。我读到一些不再支持Vista风格的地方。因此，我将代码修改如下。我还是崩溃了
CFileDialog dlg(FALSE, _T("*.xml"),strFileName ,OFN_HIDEREADONLY,
_T("(*.xml)|*.xml|(*.*)|*.*||"), NULL, 0,FALSE);
if (IDOK == dlg.DoModal()) //crash here on right click
{
//CString folder = dlg.GetFolderPath();
strFileName = dlg.GetPathName();
SetFileName ( T2CW (strFileName));
}

最佳答案
如果我从上下文菜单中禁用了NVIDIA CPL上下文菜单扩展，此问题将得到解决。然而，由于相同的代码确实适用于其他应用程序，它仍然是一个谜。
