Devc ++-未声明'IFileOperation'（C ++）

Question

I would like to add objects IFileOperation and IShellItem , but I can not fill in any way the source and gives me back:

IFileOperation - undeclared (first use in this function)

I'm using Dev-C++ with the parameters of the linker: -luuid -lole32

I suppose I must add other header but every google search is not successful. Do you have any idea?

#include <windows.h>
#include <shlobj.h>

int WINAPI WinMain(HINSTANCE hThisInstance, HINSTANCE hPrevInstance, LPSTR lpszArgument, int nFunsterStil)
{
    HRESULT     hr;
    IShellLink* pISL;

    hr = CoCreateInstance(CLSID_ShellLink,         // CLSID of coclass
                          NULL,                    // not used - aggregation
                          CLSCTX_INPROC_SERVER,    // type of server
                          IID_IShellLink,          // IID of interface
                          (void**) &pISL);         // Pointer to our interface pointer

    if(SUCCEEDED(hr))
    {
        pISL->Release();
    }
    else
    {
        // Couldn't create the COM object.  hr holds the error code.
    }

    CoUninitialize();
}

I suspect you need to link your program to Shell32.lib
try going to you program settings, then find the linker and add -lShell32.lib to it and save.

anyway, Dev-C++ is a nice compilerwhen you start programing and you want to write some code , compile it and run it. but this IDE is very ancient and unefficient , consider to move to Visual studio if you're using windows.
