Parameters
- bstrFileName
Type: System.String
[in] The file name from which to get the extension to look for.
- pdwExtnIndex
Type: System.UInt32%
[out] Returns the index into the extension list that references the extension on the given file name. Returns 0 if the extension is not in the list (0 represents "All files").
Return Value
Type: System.Int32
If successful, returns S_OK; otherwise, returns an error code.
Implements
IVsFormatFilterProvider.CurFileExtensionFormat(String, UInt32%)
Remarks
This is used to select the appropriate filter when showing a Save As dialog box to save a file.
The base method calls LanguageService.CurFileExtensionFormat to determine the index. Note that the base method translates a -1 return value to a 0 index.
