data from excel in powerpoint

[Luthor]

I downloaded the quiz from http://skp.mvps.org/ppt00031.htm. The
disadvantage of this quiz is that all the answers and questions have
to be in the VBA code. I want to use ppt as a kind of template and use
data from excel to import in the sheet (not cut and paste). In this
way I can use more than one (excel) quiz in the same presentation. I
found a way with using a txt file with the following code:

Dim FileNum, tel As Integer
Dim FileName As String
Dim InputBuffer As String
FileName = "C:\test.txt"
FileNum = FreeFile
Open FileName For Input As FileNum
tel = -1
While Not EOF(FileNum)
Input #FileNum, InputBuffer
tel = tel + 1
Qs(tel) = InputBuffer
Input #FileNum, InputBuffer
Choices(tel, 0) = InputBuffer
Input #FileNum, InputBuffer
Choices(tel, 1) = InputBuffer
Input #FileNum, InputBuffer
Choices(tel, 2) = InputBuffer
Input #FileNum, InputBuffer
Ans(tel) = InputBuffer
Wend
Close FileNum.

This works ok but I want to use excel and put a row, cell or column
from excel in powerpoint.

who knows the right VBA code to establish this???
