Hi, I'd like to know,,. 1) when I create my Dialog from CDialog class, why my Dialog does not have Destrucotr? I want to free some heap memory I used in program,,, when I write writ memory clear code? 2) class CMyView { //from somewhre(such as thread) can FuncA() {A();} //from somewhre(such as thread) can send Window Message via (SendMessage()) FuncB(WPAAM w, LPARAM l) { A();} A(){ print("A() called"); } } I'd like to know How they are diffrent? when from calling function and calling via SendMessage()? Have a day.

Hi,

Is it possible to split view windows like frame frame window with CSplitterWnd?

class CMyWnd : public CView
{
protected:
DECLARE_DYNCREATE(CMyWnd)

public:
CMyWnd();
virtual ~CMyWnd();
CSplitterWnd m_sp;
};

BOOL CMyWnd::Create(LPCTSTR lpszClassName, LPCTSTR lpszWindowName, DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID, CCreateContext* pContext)
{

m_sp.Create(this, 1,2, CSize(10, 10),
pContext);

 //CAView is subclass of CView.

if(!m_sp.CreateView(0, 0,RUNTIME_CLASS(CAview), CSize( 100, 300), pContext))return FALSE;

//CCview is subclass of CView.

if(!m_sp.CreateView(0, 1,RUNTIME_CLASS(CCview), CSize(400, 300), pContext))return FALSE;
return CWnd::Create(lpszClassName, lpszWindowName, dwStyle, rect, pParentWnd, nID, pContext);
}

After doing above, to make window I did as followings.
program die...
Is it possible to split CView window with SplitterWnd?

CMyWnd *p = new CMyWnd;
p->Create(NULL, NULL, WS_CHILDWINDOW | WS_CLIPSIBLINGS | WS_OVERLAPPED | WS_VISIBLE|WS_BORDER,
CRect (10,80, 1280,1024), this, 100, NULL);

p->ShowWindow(SW_SHOW);

when I try to "restart system" or "turn off system" , I get error message "Socket Notification Sink" Dialog box. And it didn't work reboot or turn off.. How can I avoid "Socket Notification Sink" error? My main brief code as followings. /* tread will do send something infinitely with 5 second sleep unless it is ended*/ UINT _ThreadDoSomethingInfinite(LPVOID pParam) { char buf[100]; CSocket h_sock; CMyDlg *p=(CMyDlg*)pParam; h_sock.Create( nPort , SOCK_DGRAM); while(1) { Sleep(5000); . . stcpy(buf, "some data..buffering.."); h_sock.SendTo( buf , 1234 , "127.0.0.1" ); } //will never reach... h_sock.ShutDown(2); h_sock.Close(); } CWinThread g_updsock; BOOL CMyDlg::OnInitDialog() g_updsock=AfxBeginThread(_ThreadSendAgentStatus,this,THREAD_PRIORITY_NORMAL); if(g_updsock==NULL) return; }

Hello. CDC *pDC = GetDC(); CDC tmpDC; BOOL bRet=tmpDC.CreateCompatibleDC( pDC ); //bRet is 1 => it means succes. CBitmap m_bmp; bRet= m_bmp.CreateCompatibleBitmap( pDC, rect.Width(), rect.Height() ); //bRet is 0 ==>it is an error. DWORD err=GetLastError(); //err is 8. --> it is an error. error code 8 means : "Not enough storage is available to process this command. " here, my hdd is 50M remains, and I have enough space fo runing some program... Why, CreateCompatibleDC() return error code 8? my System is abnormal? Thanks.

Hi, I can give "transaction effect" with BitBlt() on Screen in case of Bitmap image. but I'd like to know how to give "transaction effect" in case of jpg,gif and so on. === short example code === CDC MemDC; BITMAP bm; m_Bitmap.LoadBitmap(IDB_BITMAT1); m_Bitmap.GetBitmap(&bm); MemDC.CreateCompatibleDC(pDC); CBitmap* pOld = (CBitmap*)MemDC.SelectObject(&m_Bitmap); int w=bm.bmWidth; int h=bm.bmHeight; for(int j=0;j<w;j+=2) { pDC->BitBlt(0,0,j,h,&MemDC,w-j,0,SRCCOPY); } pDC->BitBlt(0,0,w,h,&MemDC,0,0,SRCCOPY); MemDC.SelectObject( pOld ); Any comment will help me! Thanks, have a day.
