default_ext() [2/2]

virtual file_dialog & xtd::forms::file_dialog::default_ext ( const xtd::ustring &  value )

virtual

Sets the default file name extension.

Parameters

value

The default file name extension. The returned string does not include the period. The default value is an empty string ("").

Remarks

When the user of your application specifies a file name without an extension, the file_dialog appends an extension to the file name. The extension that is used is determined by the filter and default_ext properties. If a filter is selected in the file_dialog and the filter specifies an extension, then that extension is used. If the filter selected uses a wildcard in place of the extension, then the extension specified in the default_ext property is used.

Returns

Current file_dialog.
