Select certain slides by check boxes in Power Point VBA - vba

Question

I need to be able to create a new .ppt (PowerPoint presentation) from selected slides in my original .ppt. The following macro will take whatever slides you currently have selected and copy them into a new .ppt. I've found the following nice code to do most of the work.
Private Sub NytPPT_Click()
'PURPOSE: Copies selected slides and pastes them into a brand new presentation file
'SOURCE: www.TheSpreadsheetGuru.com
Dim NewPPT As Presentation
Dim OldPPT As Presentation
Dim Selected_slds As SlideRange
Dim Old_sld As Slide
Dim New_sld As Slide
Dim x As Long, y As Long
Dim myArray() As Long
Dim SortTest As Boolean
'Set variable to Active Presentation
Set OldPPT = ActivePresentation
'Set variable equal to only selected slides in Active Presentation
Set Selected_slds = ActiveWindow.Selection.SlideRange
'Sort Selected slides via SlideIndex
'Fill an array with SlideIndex numbers
ReDim myArray(1 To Selected_slds.Count)
For y = LBound(myArray) To UBound(myArray)
myArray(y) = Selected_slds(y).SlideIndex
Next y
'Sort SlideIndex array
Do
SortTest = False
For y = LBound(myArray) To UBound(myArray) - 1
If myArray(y) > myArray(y + 1) Then
Swap = myArray(y)
myArray(y) = myArray(y + 1)
myArray(y + 1) = Swap
SortTest = True
End If
Next y
Loop Until Not SortTest
'Set variable equal to only selected slides in Active Presentation (in numerical order)
Set Selected_slds = OldPPT.Slides.Range(myArray)
'Create a brand new PowerPoint presentation
Set NewPPT = Presentations.Add
'Align Page Setup
NewPPT.PageSetup.SlideHeight = OldPPT.PageSetup.SlideHeight
NewPPT.PageSetup.SlideOrientation = OldPPT.PageSetup.SlideOrientation
NewPPT.PageSetup.SlideSize = OldPPT.PageSetup.SlideSize
NewPPT.PageSetup.SlideWidth = OldPPT.PageSetup.SlideWidth
'Loop through slides in SlideRange
For x = 1 To Selected_slds.Count
'Set variable to a specific slide
Set Old_sld = Selected_slds(x)
'Copy Old Slide
yy = Old_sld.SlideIndex
Old_sld.Copy
'Paste Slide in new PowerPoint
NewPPT.Slides.Paste
Set New_sld = Application.ActiveWindow.View.Slide
'Bring over slides design
New_sld.Design = Old_sld.Design
'Bring over slides custom color formatting
New_sld.ColorScheme = Old_sld.ColorScheme
'Bring over whether or not slide follows Master Slide Layout (True/False)
New_sld.FollowMasterBackground = Old_sld.FollowMasterBackground
Next x
End Sub
What I need to do, is to select which slides to copy - based on check boxes. So, for example if I select Check Box 1 = TRUE, it will create slides 1, 2 and 3. Or if I select Check box 2 = TRUE, that it could select slide 3, 4, 5 and 6. And so, if I selected both boxes it would create slides = 1, 2, 3, 4, 5, 6. Leaving out any duplicates.
I've tried a lot, including this:
Private Sub CheckBox1_Click()
If CheckBox1.Value = True Then
ActivePresentation.Slides.Range(Array(1, 2, 3)).Select
Else
MsgBox "nothing"
End If
End Sub
Private Sub CheckBox2_Click()
If CheckBox2.Value = True Then
ActivePresentation.Slides.Range(Array(3, 4, 5, 6)).Select
Else
MsgBox "nothing"
End If
End Sub
I get the error: Slide (unknown member) : Invalid request. This view does not support selection.
I am not sure how I could get this to work? Any help is appreciated, I'am very new to VBA coding.

You can switch the view to enabled the slides to be selected as follows:
ActiveWindow.ViewType = ppViewSlideSorter
For some reason, the slides aren't selected in the normal view!
But selecting things in PowerPoint brings its own challenges (as seen with the view type) and you don't need to select them in order to copy and paste them as per this example:
With ActivePresentation.Slides
.Range(Array(1, 2)).Copy
.Paste
End With
This will simplify your code as you don't need to manage windows and their views.
