Win Api

Can someone tell me why these two programs both get the same type of error:
"error C2146: syntax error : missing ';' before identifier 'Internal'"

#include "stdafx.h"
#include <winbase.h>

void CCCD_Example();


int main(int argc, char* argv[])
{
    return 0;
}

void CCCD_Example()
{
    HANDLE hnd;

    //Creates a text document on the root
    hnd = CreateFile("C:\\anew.txt", GENERIC_WRITE, FILE_SHARE_WRITE, 0, CREATE_NEW, FILE_ATTRIBUTE_NORMAL, 0);

    //Closes handle returned from CreateFile
    CloseHandle(hnd);

    //Copies the newly created file to the desktop
    CopyFile("C:\\anew.txt", "C:\\WINDOWS\\Desktop\\anew2.txt", false);

    //Goes back and deletes the first file on root C
    DeleteFile("C:\\anew.txt");
} 

and this one gets:
syntax error : missing ';' before identifier 'HDWP'

#include "stdafx.h"
#include <winuser.h>
using namespace std;


void LockDesk();


int main(int argc, char* argv[])
{
    LockDesk();
    return 0;
}


void LockDesk()
{
    HWND WinHandle = 0;

    //Locks the handle of the desktop   
    LockWindowUpdate( GetDesktopWindow());

    //Releases the desktop lock
    LockWindowUpdate(Null);
} 

If am not sure if I am making the same mistake over and over again or what?
