Code Error While Using SQL Output and ASP.NET -


i have below stored procedure in sql server 2008 not generating errors in sql, generating 1 in web application states "'getgeninfo_delete01_01_22' expects parameter '@fpath', not supplied". novice @ sql, trying return field vb.net before row deleted. suggestions helpful.

alter procedure  [dbo].[getgeninfo_delete01_01_22]    @idx int,    @fpath varchar(100) output begin select @fpath  = (select filepath geninfo_e1_01_22 id=@idx)   delete  geninfo_e1_01_22 id = @idx end

here vb code calling stored proc

                using con new sqlconnection(connstr)         using cmd new sqlcommand()             cmd.commandtype = commandtype.storedprocedure             cmd.commandtext = "getgeninfo_delete01_01_22"             cmd.parameters.add("idx", id)             dim returnparameter = cmd.parameters.add("@fpath", sqldbtype.varchar)             returnparameter.direction = parameterdirection.returnvalue             cmd.connection = con             con.open()             gridview1.datasource = cmd.executereader()             gridview1.databind()             con.close()         end using     end using

you're creating parameter returnparameter, you're not adding parameters collection. use cmd.parameters.add(returnparameter) prior db call.
