I am an novice VB user, and am a little stuck on a project I am working on. I am accessing the API to open files on a cd. What I would like to do, is access a different file depending on what the cd drive letter is. I use:

ShellExecute hwnd, "open", "D:\book2.pdf", vbNullString, CurDir$, SW_SHOW

but I would like to access a different file if the drive letter is, say, drive letter E:

any suggestions??
