VC++ 获取鼠标坐标

我想要当鼠标左键时，获取鼠标相对于窗口的坐标x,y ，然后显示在窗口中
会的大侠都来看看：
case WM_LBUTTONDOWN:
//在这里添加代码
break;

Answer 1

case WM_LBUTTONDOWN:
x=LOWORD(lParam);
y=HIWORD(lParam);
break;

Answer 2

HDC dc;
POINT point;//应该放在switch前面
....
case WM_LBUTTONDOWN:
dc=GetDC(hwnd);
GetCursorPos(&point); //鼠标位置
dc.TextOut(...);
ReleaseDC(hwnd,dc);

Answer 3

case WM_LBUTTONDOWN:
mouse_x=LOWORD(lParam);
mouse_y=HIWORD(lParam);
sprintf(str,"%d,%d",mouse_x,mouse_y);//显示坐标
TextOut(cdc,20,20,str,strlen(str));
break；

Answer 4

POINT point;
GetCursorPos(&point); //鼠标位置
cout<<(<<point.x<<,<<point.y<<)<<endl;
