I have a moduless dialog which has WS_CHILD property in a dll and used as an child in a view. when the dialog has focus ,it look the accelerator key massage as a dialog message and does not pass to it's parent(the view),while my purpose is that it should route the msg to the view and the dispatch to any it's child.Please tell me how to achieve this. some presetive code goes: In the view class: BOOL CTestAccelView::PreTranslateMessage(MSG* pMsg) { if(TranslateAccelerator(m_hWnd,m_hAccelTest,pMsg)) return TRUE; if(m_pTestDlgWnd && m_pTestDlgWnd->GetSafeHwnd() ) if(m_pTestDlgWnd->PreTranslateMessage(pMsg)) return TRUE; if(m_pTestDlgWnd2 && m_pTestDlgWnd2->GetSafeHwnd()) if(m_pTestDlgWnd2->PreTranslateMessage(pMsg)) return TRUE; return CView::PreTranslateMessage(pMsg); } In the Dialog class: BOOL CTestDlg::PreTranslateMessage(MSG* pMsg) { if(TranslateAccelerator(m_hWnd,m_hAccelTest,pMsg)) { return TRUE; } if(IsDialogMessage(pMsg)) { return TRUE; } return CWnd::PreTranslateMessage(pMsg); } Scratch

It's a good idea,but didn't fit my application. Scratch

at run time i want to known a fuction's caller ,how can? for example: void a(int i) { CString szCaller = GetTheCaller(); MessageBox(szCaller); } void b(int j) { a(j); } I'd like to get a message :"void b(int j)" How to implement method "GetTheCaller()" Scratch

Ok,that's it ,thanks. Scratch

thank you for your help,but my code goes like: In main thread. if(m_pScanThread && m_pScanThread->m_hThread != NULL) { m_pScanThread->PostThreadMessage(UWM_TIMERON,0,0); } else { m_pScanThread = AfxBeginThread((AFX_THREADPROC)fnScanProc,NULL); if(m_pScanThread && m_pScanThread->m_hThread != NULL) m_pScanThread->PostThreadMessage(UWM_TIMERON,0,0); } Thread function. CoInitializeEx(NULL,COINIT_MULTITHREADED ); try { //Do some Initialize DWORD dwRet; MSG msg; while(dwRet = GetMessage(&msg,NULL,0,0) != 0) { if(dwRet == -1) { continue; } else { if(msg.message == UWM_TIMERON) Scan(...); else DispatchMessage(&msg); } } } catch(...) { return -1;**///Here! if return then the m_pScanThread's( member of the main ///thread)member m_hThread is 0xfeeefeee ///and at this time i want to re - AfxBeginThread...** ::CoUninitialize(); } ::CoUninitialize(); return 0; Scratch

I have a thread handle,when the thread exit.the handle is invalid(0xfeeefeee). and i want to clearly when is it valid and when is it invalid. please show me a solution,thanks. Scratch

Object A was configged as "Requer Transaction" property and Object B(Actually is a databass access object to oracle and use ado to access to the datasource) was configged as "Supported Transaction" one.now A will invoke B and B must run in the Transaction context.is that practical and how to write the implement code of enlist the two transaction? thank you.

When use VB your advice is work very well,while using VC++ this seem does not work. Scratch

I am developing an application which need to pass an array from a com+ object to the client,the object runs at the server and the client app runs at a workstation.the problem is i can't get the actual array at the client's side. some represetative code follows: //.idl [id(15), helpstring("method GetAllPolicyID")] HRESULT GetAllPolicyID([in,out]long* size,[out,size_is(,*size)] long** PolicyID); //.cpp *size=pRst->RecordCount; *PolicyID=(ULONG*)CoTaskMemAlloc(*size*sizeof(ULONG)); for(long i=0;i<*size;i++) { if(!pRst->adoEOF) { vt=pRst->GetCollect("POLICYID"); (*PolicyID)[i]=vt.lVal; pRst->MoveNext(); } } Scratch

Anybody know? Scratch

When I use ICaptureGraphBuilder2::FindInterface() method to find a specific filter (say IAMVideoCompression).It give two messageboxes that "Please wait until preroll is completed!" and ASSERT Failed ((HRESULT)BreakConnect()) >=0) At line 2005 of ..\DXSDK\Samples\Multimedia\DirectShow\BaseClasses\amfi lter.cpp),but my sourcefilter doesn't need preroll and i had not add any prerolling filter to the graph.The reprentative code like : IAMVideoCompression *pVC=NULL; if(FAILED(m_pCapture->FindInterface (&PIN_CATEGORY_CAPTURE,&MEDIATYPE_Video,m_pSF7146,IID_IAMV ideoCompression,(void**)&pVC))) { return S_FALSE; } My work environment is DirectX8.1SDK + VC++6.0 + WinXP.

Hi All,I have some trouble: The symptom is I have a child window(CStatic)to display status information,it must be updated every second,after a longtime running(maybe 20 minute),then i only got a NULL DC pointer,and then system give me a notification that the resource requred can't acquire.at the same time get into mass. Any help will be appreciated. some representive code(in a method of a CStatic derived class): CDC* pDC=NULL; pDC=GetDC(); if(pDC==NULL) { TRACE("Draw Label Failed!\n"); return FALSE; } CRect rc; if(::GetClientRect(m_hWnd,&rc)) { PaintBk(pDC,rc); int iDC=pDC->SaveDC(); pDC->SetBkColor(0); pDC->SetTextColor(m_FontColor); pDC->SelectObject(&m_Font); pDC->DrawText(m_szLabel,&rc,DT_VCENTER|DT_SINGLELINE); pDC->RestoreDC(iDC); return TRUE; } Scratch
