typed dataset error

Question

I am unable to create an object of a typed dataset in the designer mode. In an application i have added a schema object and generated dataset by giving "msdatasetgenerator" in its custom tool. Now when i come to the form in design mode and add a typed dataset for that schema object, it gives me error. This error is occuring even if there are no errors after building the project. Need immediate help regarding this. Waiting for the solution Best Regards Archana
