getting error while using vb.net control in Vb.

I have created one control in Vb.net in i am using one Webservice in the contorl.Now I using this control in VB 6 , but I am getting error as
"Coult not find default endpoint element that references contract "webservice name" in the Service Model Client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching the contract cout be found in the client element "

Please do the needful.
