分享如何知道CFileDialog中扩展名选择框的当前选择项？？
我在程序中定义了如下对话框
CFileDialog saveDlg(FALSE,
"*.txt",
NULL,
OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
"C语言格式(*.txt)|*.txt|Basic格式(*.txt)|*.txt|BMP格式(*.bmp)|*.bmp||",
NULL);
第一二种格式的扩展名相同
我需要针对不同的保存格式进行不同的操作，请问我如何才能够获取当前选中的文件格式，亦即扩展名选择框当前选中项

看看CFileDialog::m_ofn的nFilterIndex
nFilterIndex
Specifies the index of the currently selected filter in the File Types control. The buffer pointed to by lpstrFilter contains pairs of strings that define the filters. The first pair of strings has an index value of 1, the second pair 2, and so on. You can specify an index on input to indicate the initial filter description and filter pattern for the dialog box. When the user selects a file, nFilterIndex returns the index of the currently displayed filter.
If nFilterIndex is zero, the system uses the first filter in the lpstrFilter buffer.
