游戏杆编程

1.#include "Mmsystem.h"

2.加入winmm.lib

3.重载WM_CREATE
int CMyView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CListView::OnCreate(lpCreateStruct) == -1)
return -1;
int result=::joySetCapture(CMyView::m_hWnd,JOYSTICKID1,0,FALSE);
if(result==JOYERR_NOCANDO)
{
        MessageBeep(MB_ICONEXCLAMATION);
        MessageBox("不能捕获游戏杆", NULL, MB_OK | MB_ICONEXCLAMATION);
}
        if(result==JOYERR_UNPLUGGED)
{
        MessageBeep(MB_ICONEXCLAMATION);
        MessageBox("游戏杆未与系统连接", NULL, MB_OK | MB_ICONEXCLAMATION);
}
// TODO: Add your specialized creation code here

return 0;
}

4.重载WindowProc
LRESULT CMyView::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
// TODO: Add your specialized code here and/or call the base class
     WORD x,y;
     switch(message)
     {
     case MM_JOY1BUTTONDOWN :
     if (wParam & JOY_BUTTON1)//如果按下按钮一
   CMyView::MessageBox("1 down",NULL,MB_OK);
   break;
     case MM_JOY1MOVE :
     UpdateData(TRUE);
     x = LOWORD(lParam)/2048;
     y = HIWORD(lParam)/2048;
     if (x<15) ;//按下左键
     if (x>15) ;//按下右键
     if (y<15) ;//按下上键
     if (y>15) ;//按下下键

break;
default:
   break;
}
return CListView::WindowProc(message, wParam, lParam);
}

5.重载WM_CREATE
void CMyView::OnDestroy()
{
::joyReleaseCapture(JOYSTICKID1);
CListView::OnDestroy();
// TODO: Add your message handler code here
}
