Hi all. I have this code in my program:

SHFILEOPSTRUCT fop;

      // initialize all data required for the copy
      fop.hwnd = NULL; 
      fop.wFunc = FO_DELETE; 
      fop.pFrom = "Documents and Settings\\All users\\Application Data\\Viewpoint\0"; 
      // fop.pTo = "A:\\";
      fop.fFlags = FOF_ALLOWUNDO;
      // remaining entries are output variables, no need to initialize

      SHFileOperation(&fop);

And it does what I tell it to do just fine and dandy. (by deleting the folder and all of it's contents)
However, when I try to put the same code in a different part of my source, and changing "fop" to "gop" (good old GOP :p ) and setting:

(Toggle Plain Text)

gop.pFrom = "Program Files\\Viewpoint\\Viewpoint Media Player\0Program Files\\Viewpoint\\Viewpoint Experience Technology\0";

Windows says it can't find the file! What am I missing here?
(This is all assuming that you put the .exe in your hard drive that Viewpoint is installed in)

Thanks.

Do you have gop every where you originally had fop and is gop pointing to a valid / existing path?

No, I have fop in one area and gop in another.

There are a couple of things I can think of, don't know if they are the problem though:

1. The help says

Quote:

pTo
Address of a buffer to contain the name of the destination file or directory. This parameter must be set to NULL if it is not used. Like pFrom, the pTo member is also a double-null terminated string and is handled in much the same way. However, pTo must meet the following specifications

Are you setting the pTo to NULL? You don't in the fop case, but you might just be "lucky" and it happens to be NULL anyways.

2. From the help again:

Quote:

If the pFrom or pTo members are unqualified names, the current directories are taken from the global current drive and directory settings as managed by the GetCurrentDirectory and SetCurrentDirectory functions.

Possibly something is changing your program's current directory before the gop version is called (e.g. a file open dialog). Try it with fully qualifies paths (i.e. stick c:\\ in front of both of the paths)
