Switching a Form's RecordSource
Many developers don't realize how easy it is to switch a form's RecordSource property at runtime. This is a great way to use the same form to display data from more than one table or query containing the same fields. It's also a great way to limit the data that's displayed in a form at a particular moment. Using the technique of altering a form's RecordSource property at runtime, as shown in Listing 10.1, you can dramatically improve performance, especially for a client/server application. This example is found in the frmShowSales form of the CHAP10EX database.Listing 10.1 begins by storing the value of the optSales option group on the frmShowSales main form into a Long Integer variable. It calls the ShowSalesValue function, which declares three constants; then it evaluates the parameter that was passed to it (the Long Integer variable containing the option group value). Based on this value, it builds a selection string for the subtotal value. This selection string becomes part of the SQL statement used for the subform's record source and limits the range of sales values displayed on the subform.
The ShowSales routine builds a string containing a SQL statement, which selects all required fields from the tblCustomers table and qryOrderSubtotals query. It builds a WHERE clause that includes the txtBeginningDate and txtEndingDate from the main form as well as the string returned from the ShowSalesValue function.
After the SQL statement has been built, the RecordSource property of the fsubShowSales subform control is set equal to the SQL statement. The RecordCount property of the RecordsetClone (the form's underlying recordset) is evaluated to determine whether any records meet the criteria specified in the RecordSource. If the record count is zero, no records are displayed in the subform, and the user is warned that no records met the criteria. However, if records are found, the form's Detail section is enabled, and focus is moved to the subform.
