    Gang,

    Are you using the Access Database (MDB) version of the Waterobjects.NET sample?

    Is the MDB file you're trying to open a valid WaterGEMS model? (does it open in WaterGEMS Standalone?)

    Have you tried placing the file in a location that you have read/write permissions to, and have you tried running your tool as admin?

    Gang,

    If you're using a version of WaterGEMS that uses the .MDB extension for model files (V8i SS3 and below) then you can find example models in the "Samples" folder within the WaterGEMS installation folder.

    If you're using a version of WaterGEMS that uses the .SQLITE extension for model files (V8i SS4 and above), then you'll need the SQLITE version of the Waterobjects.NET SDK (currently in beta). A link can be provided if needed.

    If this does not help, please provide answers to the questions in my previous reply.

    In the "Samples" folder within the WaterGEMS installation folder,there isn't the .MDB extension model files. The code trigger the bug is below:
    GenericDataSource adatasoure =new GenericDataSource ();
    adatasoure .SetConnectionProperty(ConnectionProperty.FileName,DatabasePath);
    adatasoure .SetConnectionProperty(ConnectionProperty.ConnectionType,ConnectionType.Jet4pt0);
    adatasoure .SetConnectionProperty(ConnectionProperty.EnableSchemaUpdate,false);
    adatasoure .Open();//run here the bug occur
