  首先,我弄个主窗口出来,没有用到MFC,直接调用API函数实现,先看看代码吧:

#include

#include

#include

#include

int x, int y, LPPOINT lppt);//移动当前画笔的位置

//初始化数组(地雷分布
int x_position, y_position, x_size, y_size;
set_position_size(
&x_position, &y_position, &x_size, &y_size);

static TCHAR szAppName[] = TEXT ("MainWin") ;
HWND hwnd ;

}
return msg.wParam ;
}

LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
switch (message)
{
case WM_PAINT:
paint_map(hwnd); //自定义的画图函数
return0;

case WM_LBUTTONDOWN: //单击鼠标
int x=LOWORD(lParam);//x,y为鼠标当前的位置坐标
int y=HIWORD(lParam);
left_key(hwnd, x, y);//自定义的响应鼠标左键的函数
break;

case WM_DESTROY:
PostQuitMessage (

}
return DefWindowProc (hwnd, message, wParam, lParam) ;
}

现在,看看DrawMap.h文件的一些自定义函数的声明:

//自定义函数

//设置窗口位置和大小

void left_key(HWND hwnd, int x, int y);
void DrawRec(HWND hwnd, HDC hdc, int i, int j);
RECT rectRec(HWND hwnd,
