Class Watch (Excel VBA)

The class Watch represents a range that is tracked when the worksheet is recalculated. The Watch object allows users to verify the accuracy of their models and debug problems that they encounter.

Set

To use a Watch class variable it first needs to be instantiated, for example

Dim wtc As Watch
Set wtc = Application.Watches.Add(Source:=)

The following procedures can be used to set variables of type Watch: Watches.Item, Watches.Add and Application.Watches

For Each

Here is an example of processing the Watch items in a collection.

Dim wtcWatche As Watch
For Each wtcWatche In Application.Watches
	
Next wtcWatche

Delete

Deletes the object.

Parent

Returns the parent object for the specified object. Read-only.

Source

Returns a Variant value that represents the unique name that identifies items that have a SourceType property value of xlSourceRange, xlSourceChart, xlSourcePrintArea, xlSourceAutoFilter, xlSourcePivotTable, or xlSourceQuery.

If the SourceType property is set to xlSourceRange, this property returns a range, which can be a defined name. If the SourceType property is set to xlSourceChart, xlSourcePivotTable, or xlSourceQuery, this property returns the name of the object, such as a chart name, a PivotTable report name, or a query table name.

 .Range("A3").Select

 End With 
 
End Sub
