| Property tag: | 0x3F070102 |
The PR_CONTROL_ID property contains a unique identifier for the control. This identifier should contain a GUID structure and a binary value of type LONG. All controls in the dialog box should use the same GUID to identify the service provider, and each control should use a unique LONG value to ensure that the controls do not collide.
PR_CONTROL_ID is used in notifications. For example, notifications sent on the display table must have PR_CONTROL_ID to uniquely identify the control to update.
