'GetConsoleWindow' was not declared in this scope?

Question

#include<windows.h> have already added, so why the GCC-mingw32 Compiler reported that 'GetConsoleWindow' was not declared in this scope ?

Here's my code:

#include<iostream>
#include<cmath>
#include<windows.h>

using namespace std;

#define PI 3.14

int main() 
{
    //Get a console handle
    HWND myconsole = GetConsoleWindow();
    //Get a handle to device context
    HDC mydc = GetDC(myconsole);

    int pixel =0;

    //Choose any color
    COLORREF COLOR= RGB(255,255,255); 

    //Draw pixels
    for(double i = 0; i < PI * 4; i += 0.05)
    {
        SetPixel(mydc,pixel,(int)(50+25*cos(i)),COLOR);
        pixel+=1;
    }

    ReleaseDC(myconsole, mydc);
    cin.ignore();
    return 0;
}

Thanks. ^^

From msdn:

To compile an application that uses this function, define _WIN32_WINNT as 0x0500 or later.

So you can try to replace

#include<windows.h>

with

#define _WIN32_WINNT 0x0500
#include<windows.h>

Or include SDKDDKVer.h from Windows SDK:

Including SDKDDKVer.h defines the highest available Windows platform.
