Write Event

Microsoft Outlook Visual Basic

Occurs when a Microsoft Outlook item is saved, either explicitly (for example, using the Save or SaveAs methods) or implicitly (for example, in response to a prompt when closing the item's inspector).

Sub object_Write(Cancel As Boolean)

object    An expression that evaluates to one of the objects in the Applies To list. In VBScript, use the word Item.

Cancel    Optional Boolean (not used in VBScript). False when the event occurs. If the event procedure sets this argument to True, the save operation is not completed.

Remarks

In Microsoft Visual Basic Scripting Edition (VBScript), if you set the return value of this function to False, the save operation is not completed.

Example

This Visual Basic for Applications (VBA) example uses the Write event and warns the user that the item is about to be saved and will overwrite any existing item and, depending on the user's response, either allows the operation to continue or stops it. If this event is canceled, Microsoft Outlook displays an error message. Therefore, you need to capture this event in your code. One way to do this is shown below. The sample code must be placed in a class module such as ThisOutlookSession, and the Initialize_Handler() subroutine must be called before the event procedure can be called by Microsoft Outlook.

Public WithEvents myItem As Outlook.MailItem

Private Sub myItem_Write(Cancel As Boolean)
	Dim myResult As Integer
	myItem = "The item is about to be saved. Do you wish to overwrite the existing item?"
	myResult = MsgBox(myItem, vbYesNo, "Save")
	If myResult = vbNo Then
		Cancel = True
	End If
End Sub

Public Sub Initalize_Handler()
	Const strCancelEvent = "Application-defined or object-defined error"
	
	On Error GoTo ErrHandler
	
	Set myItem = Application.ActiveInspector.CurrentItem
	myItem.Save
	Exit Sub
	
	ErrHandler:
		MsgBox Err.Description
		If Err.Description = strCancelEvent Then
			MsgBox "The event was cancelled."
		End If
End Sub
