c++ - WinAPI的CreateWindow 如何指定任务栏图标

我现在画了一个窗体,但是奇怪的是任务栏的图标并没有显示成默认的图标,而是如下图:

下面是我的全部代码,请问有啥问题:
    #include <windows.h>
    #include <stdlib.h>
    #include <string.h>
    #include <tchar.h>
    #include <stdio.h>
    #include <GL/GL.h>

    #pragma comment (lib,"kernel32.lib")
    #pragma comment (lib,"user32.lib")
    #pragma comment (lib,"opengl32.lib")
    #pragma comment (lib,"Gdi32.lib")

    LRESULT CALLBACK WndProc(HWND hWnd,UINT msg,WPARAM wPara,LPARAM lPara);
