| 1 获取程序实例 |
| HINSTANCE m_hInst; m_hInst=AfxGetInstanceHandle(); //获取程序实例 |
| 2 载入图像 |
| HBITMAP m_bmpTank； HBITMAP m_bmpBomb; m_bmpTank=LoadBitmap(m_hInst,MAKEINTRESOURCE(IDB_TANK)); m_bmpBomb=LoadBitmap(m_hInst,MAKEINTRESOURCE(IDB_BOMB)); |
| 3 将位图选入DC中 |
| HDC m_TankDC; HDC m_BombDC; m_TankDC=CreateCompatibleDC(pDC->m_hDC); m_BombDC=CreateCompatibleDC(pDC->m_hDC); //选择图像 SelectObject(m_TankDC,m_bmpTank); SelectObject(m_BombDC,m_bmpBomb); |
| 4 绘图 |
| BitBlt(pTankDC->m_hDC,0,0,TANK_WIDTH,TANK_WIDTH,m_TankDC,0,0,SRCCOPY); TransparentBlt2(pDC->m_hDC,0,0,nWidth,nHeight, m_TankDC, 0,0,nWidth,nHeight,RGB(255,0,0)); |
| 1 获得Picture的DC |
| CDC* m_pMapDC=GetDlgItem(IDC_MAP)->GetDC(); CDC* m_pTankDC=GetDlgItem(IDC_TANK)->GetDC(); |
| 2 将Picture控件移到指定矩形区域 |
| //设置客户区矩形 m_ClientRect[0]=CRect(20,10,7*WIDTH+20,WIDTH+10); //IDC_MAP m_ClientRect[1]=CRect(20,50,NUM*WIDTH+20,NUM*WIDTH+50); //IDC_FIELD m_ClientRect[2]=CRect(260,12,TANK_WIDTH+260,TANK_WIDTH+12); //IDC_TNAK //移动窗体 GetDlgItem(IDC_MAP)->MoveWindow(m_ClientRect[0]); //IDC_MAP GetDlgItem(IDC_FIELD)->MoveWindow(m_ClientRect[1]); //IDC_FIELD GetDlgItem(IDC_TANK)->MoveWindow(m_ClientRect[2]); |
| 1 载入光标 1）从文件载入光标 |
| HCURSOR m_hCursor; //Load the Cursor m_hCursor=LoadCursorFromFile("res\\cursor.ani"); //.cur or .ani |
| 2）从程序自己定义的资源光标载入 m_hCursor=AfxGetApp()->LoadCursor(IDR_CURSOR); 3）从默认资源载入 m_hCursor=LoadCursor(NULL,IDC_CROSS); |
| 2 设置光标 响应WM_SETCURSOR消息，显示适当的光标形状 if(m_hCursor) { SetCursor(m_hCursor); return TRUE; } else return CDialog::OnSetCursor(pWnd, nHitTest, message); |
| 构造函数： m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME); |
| 初始化： HICON icon=LoadIcon(AfxGetInstanceHandle(),(LPCTSTR)IDR_MAINFRAME); SetIcon(icon,TRUE); SetIcon(icon,FALSE); MCI_OPEN_PARMS mciOpen; //背景音乐 mciOpen.lpstrDeviceType=0; mciOpen.lpstrElementName="./res/music.mp3"; mciSendCommand(NULL,MCI_OPEN, MCI_OPEN_ELEMENT,(DWORD)&mciOpen); MCI_PLAY_PARMS mciPlay; mciPlay.dwFrom = 0; mciSendCommand(mciOpen.wDeviceID,MCI_PLAY,MCI_NOTIFY | MCI_FROM,(DWORD)&mciPlay); SetTimer(1,210000,NULL); //用来循环播放背景音乐 |
| OnTimer函数： OnTimer(UINT nIDEvent) { // TODO: 在此加入消息处理程序代码和/或调用默认值 if(nIDEvent==1) { MCI_PLAY_PARMS mciPlay; mciPlay.dwFrom = 0; mciSendCommand(mciOpen.wDeviceID,MCI_PLAY,MCI_NOTIFY | MCI_FROM,(DWORD)&mciPlay); } CDialog::OnTimer(nIDEvent); } |
| 控制背景音乐的播放： void CMazeDlg::OnBnClickedBkmusic() { // TODO: 在此加入控件通知处理程序代码 UpdateData(TRUE); if(m_bBkMusic) { MCI_PLAY_PARMS mciPlay; mciPlay.dwFrom = 0; mciSendCommand(mciOpen.wDeviceID,MCI_PLAY,MCI_NOTIFY | MCI_FROM,(DWORD)&mciPlay); SetTimer(1,210000,NULL); } else { KillTimer(1); mciSendCommand(mciOpen.wDeviceID,MCI_STOP,MCI_WAIT,NULL); } } |
| CWinThread *m_Thread; UINT Start(LPVOID pPar); //開始 m_Thread=AfxBeginThread(Start,GetSafeHwnd()); m_Thread->SuspendThread(); m_Thread->SuspendThread(); |
