How to disable files type combo box in Open Dialog box

Hi All,

My Visual Basic application is using Excel for reporting.

I need to restrict the users of my application to open only excel files from the File->Open dialogue box.

Or

Is there any way to make default ‘Excel files (*.xls)’ in the Files type combo box in the Open dialog box and disabling the Files type combo box, so that the users can only select excel files when they click File->Open.

Please help me in this regard.

Do you mean to filter from your vb's commondialog box or Excels built in dialog box?
