Unable to Convert WorkSheets data to Flkat Files

[Bobby]

I am trying to convert all the work sheet data to a flat file. But when i am
trying am getting that export failed. Please help to resolve this issue.

Iam getting "Export failed" when i call this ExportToFile() function using a
menu.
the function GetDefaultFileName() is previously i used to convert the single
worksheet data into a flat file. But now i need to convert the all worksheets
to the multiple flatfiles when i call this 'ExportToFile() function.
