Custom Worfklow Activity CRM 2013 RRS feed

  • Question

  • Hi,

    I'm trying to make a Custom Workflow Activity in crm2013. CWA connect to the external database and execute select command. Unfortunatelly dataset is empty and i have this exception:

    "Value cannot be null.Parameter name: source'"

    This is my code :

            public void GetData(string dsName, string tablName, string query) {
                try {
                    SqlDataAdapter adapter = new SqlDataAdapter();
                    adapter.TableMappings.Add("Table", tablName);
                    SqlCommand command = new SqlCommand(query, this.sqlConnection);
                    
                    
                    command.CommandType = CommandType.Text;
                    adapter.SelectCommand = command;
                    
    
                    dataSet = new DataSet(dsName);
                    adapter.Fill(dataSet);
                    
                } catch (Exception ex) { }
            }

    sqlConnection is open.

    What is wrong in this code ?
