Specifying Custom Filters in FileBrowser

Answer: Define a custom filter of allowable file extensions, as shown in the following code sample:

method pushButton(var eventInfo Event)
var
   fbiXFile  FileBrowserInfo   ; data for systemSaveAs() function.
   loRetval  Logical           ; Value returned to calling process.
   strValue  String            ; Holds filenames
endVar

   ; initialize local vars
   loRetval = TRUE
   strValue = "USERDATA.INI"

   fbiXFile.Title          = "Open File"
   fbiXFile.CustomFilter   = "INI Files|*.ini|All Files|*.*|"
   fbiXFile.Alias          = ":PRIV:"
   fbiXFile.DefaultExt     = "INI"

   ; Call the SaveAs wrapper function
   loRetval = getFileName( strValue, fbiXFile )

   if loRetval then

      msgInfo( "FYI", "The user chose to import " +
               strValue + "." )
   else

      msgStop( "File Browser Cancelled", "The user either cancelled " +
               "the FileBrowser or an invalid file was selected." )

   endIf

endMethod

This example prompts the user to select an INI file and may be useful if you're having trouble using the fbIni FileBrowserFileTypes for this.

Question: I'm trying to use FileBrowser() or FileBrowserEx() to prompt the user for a file using a different extension than the ones supported by AllowableTypes. How do I do this?
