Changing the DataWindow in the Web ActiveX

When you associate a DataWindow object with a DataWindow control, you are setting the initial value of the DataWindow control’s SourceFileName and DataWindowObject properties.

During execution, this tells your application to:

1. Look for DataWindow objects in the library (PBL file) or runtime library (PBD file) specified in the control's SourceFileName property.

2. Create an instance of the DataWindow object specified in the control’s DataWindowObject property (which must be in the specified library) and use it in the control.

In addition to specifying the DataWindow object in the Window painter, you can switch the object that displays in the control during execution by changing the value of the SourceFileName and DataWindowObject properties in code.

You might simply change the DataWindowObject property to use a different DataWindow object from the same library, or you might change both properties to use a DataWindow object from some other library.

This example shows the code to set the properties in JavaScript. The code changes the DataWindow object in dw_emp, a DataWindow control in a form or Web page. Dw_emp is saved as part of the form or Web page definition. The value for DataWindowObject is d_emp_hist; it was created in the DataWindow painter and is stored in the library named emp.pbl, the value for SourceFileName.

To display the DataWindow object d_emp_hist from the library emp.pbl in the DataWindow control dw_emp, you can code:

dw_emp.SourceFileName = "dwlibs/emp.pbl";

dw_emp.DataWindowObject = "d_emp_hist";
