public virtual int CurFileExtensionFormat(
	string fileName


Type: System.String

[in] The file name from which to get the extension to look for.

Return Value

Type: System.Int32

If successful, returns a zero-based index into the file extension list that is returned from LanguageService.GetFormatFilterList; otherwise, returns -1 to indicate the extension is not in the file extension list.

This is used to select the appropriate filter when showing a Save As dialog box to save a file.

The base method calls LanguageService.GetFormatFilterList and then searches the list for the extension. Note that LanguageService.GetFormatFilterList returns a single string: the extensions are separated either by newlines or vertical bars ("|") and the base method can handle either separator.
