I have an Excel file and iview32.exe I am going to put on a CD.

I use this code to find what drive user utilizes (and it works):

DriveID = Application.ActiveWorkbook.Path

While testing from my HD, I have this code to activate iview32.exe (and it works):

Shell "D:/Program Files\Irfanview\i_view32.exe /slideshow=C:\a.txt", vbNormalFocus

After I put all on CD, I will need to modify above to reflect path on CD like so:

Shell DriveID (User's CD Drive)& ":" & "\" (Concatenate this)Irfanview\iview32.exe /slideshow=C:\a.txt", vbNormalFocus (Path on CD)

Tried it, but can't get parens () and Quotes " and & in right places.
