How to refer to a placeholder of the Slide Master - vba

Question

I am trying to get the dimensions of the main placeholder in the Slide Master Text placeholder 2 - that in the code would be "MasterPlaceholder" - (whose size has been modified, and the new dimensions are pulled only in the third Layout, as shown in the picture) and set them as the basis for the resizing of all other placeholders in the other Layouts. Given a certain distance between Heading's placeholders and Body/Generic placeholders, I would like to loop through all Layouts and apply the new size.
However, I do not know how to point to this shape and I tried several ways (also "ActivePresentation.Designs(1).SlideMaster.Shapes.Placeholders.("Text Placeholder 2")", "ActivePresentation.Designs(1).SlideMaster.Shapes.Placeholders.Name("Text Placeholder 2")", but I cannot find a way to point it without errors.
Could someone please let me know how to properly refer to it? This would also help me find a way to refer to "PlcHlder", which would be the shape to be ridimensioned
Sub PlaceHolderResizer()
Dim LeftLimit As Single
Dim TopLimit As Single
Dim RightLimit As Single
Dim BottomLimit As Single
Dim DrawingAreaWidth As Single
Dim DrawingAreaHeight As Single
Dim MasterPlaceholder As Shape
Dim PlcHldr As Shape
Dim oShape As Shape
Dim HorizontalDistance As Single
Dim VerticalDistance As Single
Dim HeadingToPlaceholder As Single
HorizontalDistance = 360
VerticalDistance = 144
HeadingToPlaceholder = 144
Set MasterPlaceholder = SlideMaster.Shapes.Placeholders.Name("Text Placeholder 2")
LeftLimit = MasterPlaceholder.Left
TopLimit = MasterPlaceholder.Top
RightLimit = MasterPlaceholder.Left + oShape.Width
BottomLimit = MasterPlaceholder.Top + oShape.Height
DrawingAreaWidth = MasterPlaceholder.Width
DrawingAreaHeight = MasterPlaceholder.Height
For Each oShape In ActivePresentation.Designs(1).SlideMaster.CustomLayouts(4).Shapes
If oShape.Name = "Content Placeholder 2" Then
oShape = PlcHldr
oShape.Left = LeftLimit
oShape.Width = (DrawingAreaWidth / 2) - HorizontalDistance
End If
Next oShape
End Sub

Answer 1

On the slide master, there can only be one text placeholder. So you can use the placeholder Type property to identify it and get its name:
Sub GetPlaceHolderName()
Dim oShape As Shape
For Each oShape In ActivePresentation.SlideMaster.Shapes
If oShape.PlaceholderFormat.Type = ppPlaceholderBody Then
MsgBox oShape.Name
End If
Next oShape
End Sub
Looping through object collections to get names is par for the course with PowerPoint VBA, you'll use that technique very often.

Answer 2

As in https://learn.microsoft.com/en-us/office/vba/api/powerpoint.placeholders, I assigned the Index 2 to the shape (because there is a title, which would be 1) and finally the placeholder was re-dimensioned (the size at this moment does not matter, since it is something I will fix later). The code still needs great improvement, but at least I saw some action in the item I was referring to.
I will have to find a way to point to the placeholder by name somehow, something more talkative than an index number.
Sub PlaceHolderResizer()
Dim LeftLimit As Single
Dim TopLimit As Single
Dim RightLimit As Single
Dim BottomLimit As Single
Dim DrawingAreaWidth As Single
Dim DrawingAreaHeight As Single
Dim MasterPlaceholder As Shape
'Dim PlcHldr As Shape
Dim oShape As Shape
Dim HorizontalDistance As Single
Dim VerticalDistance As Single
Dim HeadingToPlaceholder As Single
HorizontalDistance = 72
VerticalDistance = 144
HeadingToPlaceholder = 144
Set MasterPlaceholder = ActivePresentation.SlideMaster.Shapes.Placeholders(2) ' here is how I should have called it
LeftLimit = MasterPlaceholder.Left
TopLimit = MasterPlaceholder.Top
' RightLimit = MasterPlaceholder.Left + oShape.Width
' BottomLimit = MasterPlaceholder.Top + oShape.Height
DrawingAreaWidth = MasterPlaceholder.Width
DrawingAreaHeight = MasterPlaceholder.Height
For Each oShape In ActivePresentation.Designs(1).SlideMaster.CustomLayouts(4).Shapes
If oShape.Name = "Content Placeholder 2" Then
' oShape = PlcHldr
oShape.Left = LeftLimit
oShape.Width = DrawingAreaWidth - HorizontalDistance
End If
Next oShape
End Sub
