ShellExecute won't open PDFs

[AndyGroom]

I've written some code for opening a file when it's double-clicked. It works fine on my machine for every type of file, but on one machine in the office it refuses to open PDF files. We've installed Acrobat 7 afresh, and it will open PDF files from Explorer when you double-click them, and all other types of files open when they are double-clicked in my app, except for PDFs.

Is there any reason why PDFs won't open in VB just on one machine?

how are you calling the file exe?
i had a similar problem with adobe and all i needed to do was open adobe to get past the lisense agreement then it was ok.
this by the sound of things is not the case but it is worth a try.
The other idea i have is the paths and associations in the registers are you getting the paths in the vb from the association area in the reg or are you using a shell thing?

I'm using the same API call regardless of what type of file is double-clicked;

ShellExecute 0&, "Open", F$, "", "", SW_ShowMaximized

where F$ is the file to be opened. Like I say this approach works fine with PDF files on other machines, it's just one machine that refuses to work. In that sense it's not really a VB question I suppose, I just hoped someone might have a suggestion.

Have you tried specifying a directory rather than a null string?

I've had problems in the past with PDFs and specifying a path has fixed it. You could also check the result returned by ShellExecute as this normaly tells you why it's failed.

These are the errors I usually check for.

Const SE_ERR_FNF = 2&
Const SE_ERR_PNF = 3&
Const SE_ERR_ACCESSDENIED = 5&
Const SE_ERR_OOM = 8&
Const SE_ERR_DLLNOTFOUND = 32&
Const SE_ERR_SHARE = 26&
Const SE_ERR_ASSOCINCOMPLETE = 27&
Const SE_ERR_DDETIMEOUT = 28&
Const SE_ERR_DDEFAIL = 29&
Const SE_ERR_DDEBUSY = 30&
Const SE_ERR_NOASSOC = 31&
Const ERROR_BAD_FORMAT = 11&
