Change Resource Group ID for Open Jobs

I found a slightly modified version of this code that seems to work well. I found it here:

private void epiButtonC1_Click(object sender, System.EventArgs args)
	{
	// ** Place Event Handling Code Here **
	
	DynamicQueryAdapter yourbaq = new DynamicQueryAdapter(this.oTrans);
	DataTable results;
	yourbaq.BOConnect();
	string baqname = "ChangeOpenJobResGrpIDs";
	Ice.BO.QueryExecutionDataSet dsBAQ = yourbaq.GetQueryExecutionParametersByID(baqname);
	dsBAQ.ExecutionParameter[0].ParameterID = "OldResGrpID";
	dsBAQ.ExecutionParameter[0].IsEmpty = false;
	dsBAQ.ExecutionParameter[0].ParameterValue = epiTextBoxC1.Value.ToString();
	dsBAQ.AcceptChanges();
	yourbaq.ExecuteByID(baqname, dsBAQ);
	
	// Set results of query to the grid view
	epiUltraGridC1.DataSource=yourbaq.QueryResults.Tables["Results"].DefaultView;
	}

This works great so far. Thanks Daryl! I will get on the update portion next.
