  • Hi Radika,

    As the figure shows, I guess this error might be related with the code inside of your application, could you please share us the code snippet against this issue?

    Also you could try to check out with the database connection string inside of application’s configure file.

  • Hi thanks for the reply

    In our application for the data access layer we use XSD data set for creating adapter for related entity tables. The problem is adapter not working when we run the data preview on design pane the application is running without errors and giving data at run time. Only worry is XSD deign time it won’t loading the data and also we check it won’t generate update insert delete methods. ( all the tables we created not loading data at design time)

    We have copied project to another machine it loads data without getting any error in design pane.  

    Can it be .net error becouse if we create test project with connecting adapter in design time it gives same errors

    Kind regards

  • Are you sure the two machines are absolutely identical? If not, then you should first check the differences between the two machines if that might explain the dirrent behaviors in different environments.

  • I decide to reinstall VS 2008. But need to uninstall it completely from the system. Well come any help on uninstalling the VS 2008 professional completely. Because if we uninstall VS the legacy data remains I don’t know how this happen.

  • Radika,

    If a development part runs on computer A but not on computer B then it is seldom a development problem. This are the Microsoft Developers forums you know.

    If it is a technical problem then ask it in the Technet forums,

    Be aware it can be something as a wrong or not installed framework version. Hard to say from the point of view of developers.
