    UniException Class
    In This Topic
    The exception that is generated when server returns an error.
    Syntax
    Remarks
    This class is created whenever the Universal .NET Data Provider encounters an error generated by the server, or UniConnection has been closed before attempting to execute an operation on the server.
    Example
    The following example generates a UniException due to a missing database, and then displays the exception.
    public void ThrowUniException()
    {
      string mySelectQuery = "SELECT * FROM Test.Dept";
      UniConnection myConnection =
        new UniConnection("Provider=SQL Server;Data Source=SERVER;Initial Catalog=Northwind;User ID=sa");
      UniCommand myCommand = new UniCommand(mySelectQuery,myConnection);
      try
      {
        myCommand.Connection.Open();
      }
      catch (UniException myException)
      {
        MessageBox.Show("Message: " + myException.Message + "\n");
      }
    }
    Public Sub ThrowUniException()
      Dim mySelectQuery As String = "SELECT * FROM Test.Dept"
      Dim myConnection As New UniConnection _
        ("Provider=SQL Server;Data Source=SERVER;Initial Catalog=Northwind;User ID=sa")
      Dim myCommand As New UniCommand(mySelectQuery, myConnection)
      Try
        myCommand.Connection.Open()
      Catch myException As UniException
        MessageBox.Show("Message: " + myException.Message + ControlChars.Cr)
      End Try
    End Sub
