How do i read a text file to update a text box during a show?

[Guest]

I wante to update a text box from a file. It needs to run during the show or
at file load up. I am trying to create a quiz show for use at the youth
group and will need to change the questions weekly, so it would be much
easier if I can just update a text file.

Max,
You can't do that natively in Powerpoint but there is an add-in that does
the trick for you, not free but worth a try:

Luc's suggestion might work for you. Otherwise, you will have to resort
to writing it yourself in VBA. Here is some sample code that will read
three lines from a text file name mytestfile.txt. For slide 2, it will
change shape 1 to be whatever is in the first line, shape 2, to be
whatever is in the second line, and shape 3 to be whatever is in the
third line. Shape 1 could be a text box for the question and shapes 2 and
3 could be boxes for the answers.

This code doesn't provide any error-checking, and it only reads one
question, but if you are going to resort to code, it should get you
started on what you need. It could fairly easily be made more complicated
to loop through a whole file and create slides as needed to put in more
questions, but I don't have time to make this perfect right now. Let us
know if you want to try this, and if you need help with it.

Sub AdjustQuestion()
Const ForReading = 1, ForWriting = 2, ForAppending = 8
Dim fs, f
Dim theQuestion As String
Dim answer1 As String
Dim answer2 As String
Set fs = CreateObject("Scripting.FileSystemObject")
Set f = fs.OpenTextFile("mytestfile.txt", ForReading, TristateFalse)
theQuestion = f.readline
answer1 = f.readline
answer2 = f.readline
ActivePresentation.Slides(2).Shapes(1).TextFrame.TextRange.Text _
= theQuestion
ActivePresentation.Slides(2).Shapes(2).TextFrame.TextRange.Text _
= answer1
ActivePresentation.Slides(2).Shapes(3).TextFrame.TextRange.Text _
= answer2

f.Close
End Sub

You could plug all of your text into Excel then copy/paste special, link it into
PowerPoint. Change the Excel file and the PPT will change at startup.

Other than that, an addin like the one Luc mentions or our PPTMerge
(http://merge.pptools.com) would do it.

Or if you're handy with hammer, nails, duct tape and visual basic, you could
write your own.
