Hello freinds

Error in Database Access :

"The type initializer for 'Replink.Modules.ReplinkAdvancedProductSearch.DataProvider' threw an exception."

 

Error happening in the following code :
return DataProvider.Instance().getSaveListNames(ModuleId, UserId);
 
Any idea why this error? is that something because of error in code ?
 
 
 
AdvancedProductSearchController.cs

public class AdvancedProductSearchController    //: ISearchable, IPortable
    {
        #region Constructors
        public AdvancedProductSearchController()
        {
        }
        #endregion

        public DataTable getSaveListNames(int ModuleId, string UserId)
        {
            return DataProvider.Instance().getSaveListNames(ModuleId, UserId);
        }

        public DataTable getProductIds(int ModuleId, string UserId, string SaveListName)
        {
            return DataProvider.Instance().getProductIds(ModuleId, UserId, SaveListName);
        }

        public int addSaveList(int ModuleId, string UserID, string SavelistName, string ProductIDs)
        {
            return DataProvider.Instance().addSaveList(ModuleId, UserID, SavelistName, ProductIDs);
        }

        public int appendSaveList(int ModuleId, string UserID, string SaveListName, string ProductIDs)
        {
            return DataProvider.Instance().appendSaveList(ModuleId, UserID, SaveListName, ProductIDs);
        }

        public int updateSaveList(int ModuleId, string UserID, string SaveListName, string ProductIDs)
        {
            return DataProvider.Instance().updateSaveList(ModuleId, UserID, SaveListName, ProductIDs);
        }

        public int deleteSaveList(int ModuleId, string UserID, string SaveListName)

Hello,

the problem fixed by following the below instructions :

Source : http://www.ventrian.com/Support/ProductForums/tabid/118/view/topic/postid/6132/Default.aspx

1)  Make sure that both the sqlDataProvider class and the DataProvider class are in the same namespace.
2)  Verify those namespaces using the object browser in visual studio
3)  Verify that the solution outputs the dlls for both the module and data provider projects to the dotNetNuke bin directory
4)  the CreateObject call in the dataProvider class should be as follows:

CreateObject("data", "<NAMESPACE OF DATAPROVIDERS>", "<NAME OF MODULE DLL>", DataProvider)

Where the following explainations apply:

<NAMESPACE OF DATAPROVIDERS> = The namespace of the dataprovider class in the module project and the namespace of the sqldataprovider class in the dataProvider project (they should be in the same namespace).

<NAME OF MODULE DLL> = This is the name of the module dll that should be compiled into the dotNetNuke bin directory when the project is built (minus the ".dll" extension).

thank you........
