ASPathName Value

I have been going around in circles trying to add a value to ASPathName and was wandering if anybody could provide me with an example.

Say I have a file c:\test.pdf

and when I click any action which displays an AVAppOpenDialog I want this file to be returned.

So Say I click Open...

Instead of opening a dialog to let the user choose their desired pdf I have the following code,

ASFile asFile;

char *filePath = "/C/test.pdf";

asPathName = ASFileSysCreatePathFromDIPath(ASGetDefaultFileSys(), filePath, 0);

ASFileSysOpenFile(ASGetDefaultFileSys(), asPathName, ASFILE_READ, (ASFile *)&asFile);

*outNumASPathNames = 1;

*outASPathNames = &asPathName;

*ioChosenFilterIndex = -1;

*outFileSys = ASGetDefaultFileSys();

ASFileSysReleasePath(0,asPathName);

This does open up the desired pdf, but i get an error message

Could not open the file 'ASFileHandle'. What does this mean? And am I doing something wrong?
