Can anyone explain this PDF & Visual Basic issue to me...?

I've got a PDF manual that I received from a vendor that's password
protected against changes, but can be viewed and printed.

If I do a Start | Run | g:\test\manual.pdf, the file opens in the Windows
associated program (Acrobat Reader) with the titlebar showing "Manual.pdf
(SECURED)".

When in Visual Basic, if I issue a ShellExecute command that basically does
the same thing, but I get a "File Not Found" error returned and Acrobat
never opens.

I know the VB code is correct because on non-password protected pdfs, both
ways work identical. I don't understand why it'll open using Windows just
fine but when called from VB it errors.

Any help would be greatly appreciated. Thanks...JR

YOU may 'know' the VB code is correct, but we don't. You really have
to post your code -- not just similar code, but cut and pasted from
your app. Then you might get a useful response.

The only thing I can imagine is that you don't provide the working
folder in the ShellExecute API.

Please post the code containing the ShellExecute call.
