isn`t it possible to pass a datatable with a webservice to another .net app
???

my webservice raises an exception whenever i declare the datatable type

this doesn`t work
<WebMethod(MessageName:="dtModules")> _

Public Sub CarsHaveModules(ByVal dt As DataTable )

End Sub

this  works

<WebMethod(MessageName:="dsModules")> _

Public Sub CarsHaveModules(ByVal ds As DataSet )

End Sub

is this normall behavior ????
