PowerPoint (VBA?) Fades in and out of text

Question

Trying my first visit to VBA in PPT, a little done in Excel before .. but I need help on where to go with this ...

I have a list of hundreds of lines that I want to fade in and out, on the same slide after about three or seconds of displaying 1 at a time. And continue to do this until the user stops, i.e. CTRL + break. So far I am coding a little bit, but I don’t know where to go from here ...

Option Explicit
Public Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Sub Test()
'Start the presentation
ActivePresentation.SlideShowSettings.Run

'Change the value of the text box to String1 and fade in the text
ActivePresentation.Slides(1).Shapes(1).TextFrame.TextRange.Text = "String1"

DoEvents

'Wait 2 secounds, fade out the Hello! Sting

Sleep 2000

'Fade in the new string.. String2!
 ActivePresentation.Slides(1).Shapes(1).TextFrame.TextRange.Text = "String2"

DoEvents

'A Loop to keep going back and forth between the 2 (there will be many more later....
'Until stoped by the user [CTRL + BREAK]

End Sub

Option Explicit
Public Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)

Sub Test()
'Start the presentation
ActivePresentation.SlideShowSettings.Run

'Change the value of the text box to String1 and fade in the text
ActivePresentation.Slides(1).Shapes(1).TextFrame.TextRange.Text = "String1"

DoEvents
'Wait 2 secounds, fade out the Hello! Sting

Sleep 2000

'Fade in the new string.. String2!
ActivePresentation.Slides(1).Shapes(1).TextFrame.TextRange.Text = "String2"

DoEvents

'A Loop to keep going back and forth between the 2 (there will be many more later....
'Until stoped by the user [CTRL + BREAK]

End Sub

I really appreciate any help that the forum / people can offer .. thanks!

Answer 1

You should use regular animation instead of VBA.

Make two identical text boxes with different texts, then fade out and fade out the others.
