The CreateEventProc method creates an event procedure in a class module.

expression A variable that represents a Module object.

Parameters

Name

Required/Optional

Data Type

Description

EventName

Required

String

The name of an event.

ObjectName

Required

String

An object that has the event specified by the eventname argument. If the event procedure is being added to a Form, the word "Form" should be specified for this argument. If the event procedure is being added to a Report, the word "Report" should be specified for this argument. If the event procedure is being added to a Control, the name of the control should be specified for this argument.

Return Value

Long

Remarks

The value returned by the CreateEventProc method indicates the line number of the first line of the event procedure.

The CreateEventProc method creates a code stub for an event procedure for the specified object. For example, you can use this method to create a Click event procedure for a command button on a form. Microsoft Access creates the Click event procedure in the module associated with the form that contains the command button.

Once you've created the event procedure code stub by using the CreateEventProc method, you can add lines of code to the procedure by using other methods of the Module object. For example, you can use the InsertLines method to insert a line of code.

Example

The following example creates a new form, adds a command button, and creates a Click event procedure for the command button:

Function ClickEventProc() As Boolean 
 Dim frm As Form, ctl As Control, mdl As Module 
 Dim lngReturn As Long 
 
 On Error GoTo Error_ClickEventProc 
 ' Create new form. 
 Set frm = CreateForm 
 ' Create command button on form. 
 Set ctl = CreateControl(frm.Name, acCommandButton, , , , _ 
 1000, 1000) 
 ctl.Caption = "Click here" 
 ' Return reference to form module. 
 Set mdl = frm.Module 
 ' Add event procedure. 
 lngReturn = mdl.CreateEventProc("Click", ctl.Name) 
 ' Insert text into body of procedure. 
 mdl.InsertLines lngReturn + 1, vbTab & "MsgBox ""Way cool!""" 
 ClickEventProc = True 
 
Exit_ClickEventProc: 
 Exit Function 
 
Error_ClickEventProc: 
 MsgBox Err & " :" & Err.Description 
 ClickEventProc = False 
 Resume Exit_ClickEventProc 
End Function
