Module.CreateEventProc method (Access)
The CreateEventProc method creates an event procedure in a class module.
Syntax
expression.CreateEventProc (EventName, ObjectName)
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.
After 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
