sql - VB.net Passing parameter to function with a stored procedure -


i trying call function populate datatable, not working , lost. getting function error. function doesn't return value on code paths. here's code please thank you.

protected sub search_click(sender object, e eventargs) handles search.click         strpartnumber = txtpartnumber.text              dim ct datatable = me.getcompanyinfo(strpartnumber, "none")             dvcommon.datasource = ct             dvcommon.databind()     end sub  private function getcompanyinfo(byref partnumber string, byref version string) datatable         dim constr string = configurationmanager.connectionstrings("defaultconnection").connectionstring         using con new sqlconnection(constr)             using cmd new sqlcommand("spcommoninfo")                 cmd.connection = con                 cmd.commandtype = commandtype.storedprocedure                 cmd.parameters.addwithvalue("@partnumber", partnumber)                 cmd.parameters.addwithvalue("@version", version)                 using sda new sqldataadapter(cmd)                     dim ct new datatable()                     sda.fill(ct)                 end using             end using         end using     end function

as far see method getcompanyinfo returns datatable as datatable no in code returning one.

you should return datatable have filled

return ct

your function code should be

private function getcompanyinfo(byref partnumber string, byref version string) datatable         dim constr string = configurationmanager.connectionstrings("defaultconnection").connectionstring         using con new sqlconnection(constr)         dim ct new datatable()             using cmd new sqlcommand("spcommoninfo")                 cmd.connection = con                 cmd.commandtype = commandtype.storedprocedure                 cmd.parameters.addwithvalue("@partnumber", partnumber)                 cmd.parameters.addwithvalue("@version", version)                 using sda new sqldataadapter(cmd)                                         sda.fill(ct)                 end using             end using         end using      return ct     end function
