Powerpoint - VBA - Slide status - vba

Question

I hope you are doing well.
I am a little stuck on a macro scripting, I would like to perform the following
Once the macro is launch ; create a form rectangle with attributes (see below)
If a rectangle already exist within the active slide the delete it.
Here is the little macro code written to insert the shape
Sub TBU()
Dim oSh As Shape
Set oSh = ActiveWindow.Selection.SlideRange.Shapes.AddShape(msoShapeRectangle, 902, 5, 47, 27)
With oSh
With .TextFrame.TextRange
.Text = "[TBU]"
With .Font
.name = "Arial"
.Size = 12
.Bold = msoFalse
.Italic = msoFalse
.Underline = msoFalse
.Shadow = msoFalse
.Emboss = msoFalse
.BaselineOffset = 0
.AutoRotateNumbers = msoFalse
.Color = RGB(255, 0, 0)
End With
End With
With oSh
.Fill.Visible = msoTrue
.Fill.ForeColor.RGB = RGB(255, 255, 0)
.Fill.Solid
End With
End With
End Sub
I tried to delete the shape within the active slide only if a rectangle with the same attributes already existed but got stuck on that.
Does anyone has an idea?
Kind regards,

I think the best way to find any shapes that you want to delete is to iterate over all the shapes in the current slide, and call a function that checks if the shape given matches your criteria.
It would look something like the code below. Basically, any one condition not matching is sufficient to say that the shape shouldn't be deleted. Therefore the function starts off by assuming that the shape should be deleted until it finds any condition that indicates otherwise, at which point it changes the return value to false and ceases checking for the given shape.
Dim i as Long
Dim sh as Shape
For i = ActiveWindow.View.Slide.Shapes.Count to 1 Step -1
Set sh = ActiveWindow.View.Slide.Shapes(I)
If ShouldBeDeleted(sh) Then
sh.Delete
End If
Next
'...
Function ShouldBeDeleted(sh as Shape) as Boolean
ShouldBeDeleted = True
'Repeat this IF structure for each criteria.
If sh.Fill.Visible <> msoTrue Then
ShouldBeDeleted = False
Exit Function
End If
If Not sh.HasTextFrame Then
ShouldBeDeleted = False
Exit Function
End If
'... keep repeating these if structures.
End Function
