Modify the working directory of a .lnk file (shortcut file)

I need to change the working directory for a massive amount of *.lnk files in sub directories from a root directory. Everything I've found concerning *.lnk files has been on how to create them using iShellLink and I can't seem to figure out how to simply open an existing shortcut, change its working directory (I know its SetWorkingDirectory, but just initializing the shortcut as a object is the problem I'm having), then saving the changes.

Any help will be greatly appreciated.

jkr,

Thank you for the code, however I'm getting a fail with

hres = CoCreateInstance(CLSID_ShellLink, NULL, CLSCTX_INPROC_SERVER,IID_IShellLink, (LPVOID*)&psl);

I have objbase and shlobj included as well as ole32.lib and shell32.lib linked so I have no clue why that is failing.

What is the HRESULT value that is returned?

I see a return value of -2147221008 for it. No clue what that is, but it doesn't match S_OK, REGDB_E_CLASSNOTREG, or CLASS_E_NOAGGREGATION . Maybe I'm wrong on that though...

...aka 0x800401F0

I suspect you have not called 'CoInitialize()' :o)
