Unable to call SHGetKnownFolderPath() even with #include <Shlobj.h> and #pragma comment (lib, “Shell32.lib”)

Question

(Visual Studio 2010 / Visual C++ / Windows 7)

example.cpp:

#include <Shlobj.h>
#pragma comment (lib, "Shell32.lib")    
...
void example()
{
    SHGetKnownFolderPath(...) // undefined
}

I'm doing everything according to documentation and what I see in other threads, but it still doesn't work.

Answer 1

I had exactly the same problem. Another project with the same code and ancillary files (but different includes) was working.

Putting #include <Shlobj.h> at the top of the file solved the problem.

It might not be replicable though, as it should have worked without doing that. Probably another Visual Studio bug.

Answer 2

Try putting following statement before all includes:

#define WINVER 0x0600
#define _WIN32_WINNT 0x0600

Since the documentation says it needs Vista/2008 minimum.
