Note Tag values are added and stored in uppercase text. You should perform tests on tag values using uppercase text, as shown in the second example.
This example adds a tag named "REGION" and a tag named "PRIORITY" to slide one in the active presentation.
With Application.ActivePresentation.Slides(1).Tags
.Add "Region", "East" 'Adds "Region" tag with value "East"
.Add "Priority", "Low" 'Adds "Priority" tag with value "Low"
End With
This example searches through the tags for each slide in the active presentation. If there's a tag named "PRIORITY," a message box displays the tag value. If the object doesn't have a tag named "PRIORITY," the example adds this tag with the value "Unknown."
For Each s In Application.ActivePresentation.Slides
With s.Tags
found = False
For i = 1 To .Count
If .Name(i) = "PRIORITY" Then
found = True
slNum = .Parent.SlideIndex
MsgBox "Slide " & slNum & " Priority: " & .Value(i)
End If
Next
If Not found Then
slNum = .Parent.SlideIndex
.Add "Priority", "Unknown"
MsgBox "Slide " & slNum & " Priority tag added: Unknown"
End If
End With
Next
