Import from Excel in Web

Hi

I have a button on a form in my application.On click of it i’m calling an agent to import data from an excel sheet.

However I can’t choose file name and i have to hard code it.

Is there a way where users can select the desired file name?

Like

Workspace.OpenFileDialog( False , “Select File to Import” , “Excel files (.xls)|.xls” )

This code works only in client. But i want same thing to happen in web also.

Please help.
