I have a "save as" button in my front panel and when I press this button a dialog apears which asks me a path for savaing a file into a "xls" format. In this case every time I press the "Save As" button I have to type the file extention ".xls" along with the file name.
Now how can I predefine the format ".xls" as default then when I press the "save as" button it wont be necessary to type the extention (.xls) too?
