VBA Powerpoint: add list number in a column table

Hello Experts,
I have the following procedure that I use in my personal.xlsb in order to quickly add list number in an specific column:
Sub Add_List_Number()
Dim strCol As String
Dim lngLastRow As Long
Dim lngRow As Long
Dim intPos As Integer
Dim strPrefix As String

strCol = InputBox("Please enter the column letter in which you add specific row number", "Choose Column Letter")
lngLastRow = Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).row

    For lngRow = 1 To lngLastRow
    Cells(lngRow, strCol).Value = lngRow
End Sub

Open in new window

I would like to take it as a reference to add list number in a column table in power point. Every time when a set up table in power point I use list number and when I add additional row I need to retype list number manually. I would like to add this procedure in my powerpoint add in in order to avoid to perform this task manually.

Thank you again for your feedback.

In PowerPoint there  are limited options for vba event codes. Check the below code it will insert serial number to a PowerPoint  table in 1st column. make sure to select the table before running.

Sub TableSerialnumbers()

    Dim Shp As Shape
    Dim oTbl As Table
    Dim RowsCount As Long
    Dim ColumnsCount As Long

'Select the table before running the code, code will place serial number to the 1'st column

    Set Shp = ActiveWindow.Selection.ShapeRange(1)
    With Shp
If .HasTable Then
            Set oTbl = Shp.Table
            With oTbl
                'Debug.Print .Rows.Count
                'Debug.Print .Columns.Count

                For ColumnsCount = 2 To .Rows.Count

                    With .Cell(ColumnsCount, 1)
                    .Shape.TextFrame.TextRange.Text = ColumnsCount - 1
                    End With
                End With
End If
            End With
End Sub

Noted, thank you. Last question: if you don't use add in how do you call recurrent procedures in PPT vba as in PPT there is not available the personal.xlsb as excel?
abbas abdullaCommented:
I normally store the codes in same file, but for your case you can create master file as Macro enabled format .pptm and then keep this file opened to call procedures from whenever you need them.
