l_filename := WEBUTIL_FILE.FILE_OPEN_DIALOG('c:\','*.xls','*.xls','Upload Excel File');
The code above doesn't run as expected. I see these on dialog box:
File name : *.xls
Files of type: All Files(*.*)
What I've been doing wrong? I want to see only folders and excel files when the dialog box appears, but I can see all types now like pdf's and word documents.
