SUMMARY

On Page 126 of the Visual Basic Programmer's Guide, it incorrectly states that all controls have an implicit property you can use for storing or retrieving values. Some controls supplied with the Professional Edition of Visual Basic for Windows use the Name property as their implicit property, which you cannot use at run-time.

MORE INFORMATION

The following controls from the Visual Basic Professional Edition use the Name property as their implicit property:

Common dialog
MAPI session
MAPI message
Spin button

Attempting to access the implicit property of these controls results in one of the following errors:

'Name' property cannot be read at run time
'Name' property cannot be set at run time

You access the implicit property of a control (also known as the "value of a control" or the "default value of a control") by writing the control name with no property. For example, with a text box named Text1, you can write the following statement to assign a value to the Text property:

   Text1 = "hello world"

The following list shows the implicit properties for all the controls in both the Standard and Professional Editions:
