DOCUMENT:Q161156 01-AUG-2001 [vbwin] TITLE :HOWTO: Create A Default Event for a UserControl PRODUCT :Microsoft Visual Basic for Windows PROD/VER: OPER/SYS: KEYWORDS:kbusage kbCtrlCreate kbVBp500 kbVBp600 kbGrpDSVB kbCtrlCreat ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual Basic Control Creation Edition for Windows, versions 5.0, 6.0 - Microsoft Visual Basic Enterprise Edition for Windows, versions 5.0, 6.0 ------------------------------------------------------------------------------- SUMMARY ======= You can create default events for your User Controls. A default event is the event selected when you double-click on the control in design mode. For example, when you double-click on a CommandButton, the code window creates a sub-procedure for Command_Click. Therefore, click is the default event for the CommandButton. This article will explain how to create a default event for a UserControl that you create. MORE INFORMATION ================ To create a default event, first you must create the event by doing the following: 1. Start a new ActiveX Control project in Visual Basic. 2. From the View menu, select "Code" to open the control's code window. 3. From the Tools menu, select "Add Procedure." 4. In the "Add Procedure" dialog box, enter the Event name, and check the Event option in the Type frame. 5. Click OK. NOTE: You must use the RaiseEvent command to actually trigger your event while the User Control is in use. Creating an event simply creates an event: it does not add any code that causes the event to occur. After the event is created, follow these steps to make the event the default event: 1. From the Tools menu, select Procedure Attributes. 2. In the Procedure Attributes dialog box, select the event name you previously entered. 3. Add a Description, if desired, and select Advanced>>. 4. Select the User Interface Default check box in the Attributes frame. 5. Click OK. When using the UserControl in a Visual Basic form, double-clicking on the control will create a procedure for the event you specified. You can only have one default event for each control. Therefore, you can only select the "User Interface Default" check box for one event. If you select this checkbox for another event, it will ask you if you want to make the newly-selected event the default event.
