I think in if comparision you have used NY_CATID. Previously it is MY_CATID. So verify it once.

Thanks a lot buddy. Sure.. Arun

Hi Steve, You are amazing. The change worked. But when iam building the server, it again modifying the registry setting to default Marshaller GUID. How to set my ProxtStub GUID as default?

Hi Steve, i found two registry entries.. 1st Entry

Windows Registry Editor Version 5.00

Sorry Steve. Im new to the message posts. I will follow ur guidelines for sure from next time. Coming to our discussion, iam getting the message box only once, meaning that only one byte is marshalled.

IDL File Entry: [id(5),helpstring("method SetData")] HRESULT SetData([in] ULONG size, [in,size_is(size)] BYTE *pData); Method Override: STDMETHODIMP CDataProvider::SetData(ULONG size, BYTE* bytArray) { // TODO: Add your implementation code here BYTE byt[6]; int i=0; for(;*bytArray!=0;i++) { byt[i]=*bytArray; ::MessageBox(NULL,(LPCTSTR)"he","Msg",MB_OK); bytArray++; } byt[i]=0; return S_OK; } Client: IDataProvider* pServer=NULL; HRESULT hr=::CoCreateInstance(CLSID_CDataProvider,NULL,CLSCTX_LOCAL_SERVER,IID_IDataProvider,(LPVOID*)&pServer); short sSize = 5; BYTE* pBytes; //Allocate the shared Memory pBytes = reinterpret_cast(CoTaskMemAlloc(sSize * sizeof(BYTE))); if(pBytes == NULL) return; ::memset(pBytes, 0, sSize); pBytes[0]='K'; pBytes[1]='K'; pBytes[2]='R'; pBytes[3]='D'; pBytes[4]=NULL; pServer->SetData(5,pBytes); CoTaskMemFree(pBytes); //Free the shared Memory

Ya i did the same way by copying you code.Still not able to access the entire array. Can you send me a working client server codes developed in VC98 or VS2003? My Id: k_arunkumar_1217@yahoo.com

Hi Stephen, What do you mean by Code highlights?

I have a Project named BytComp and BytCompPS in my workspace. I built the BytCompPS and found ByCompPS.dll and registered it using regsvr32 command. Now, i have added a new interface method as suggested by you but still im not able to access the entire array. :doh:

Im using Visual Studio 2003. In that i have taken an ATL Project. Server type is: Service(exe) which exposes IServicer interface.

Hi Steve, Thanks a lot for the code. How to register the Proxy-Stub of my Outproc dll or exe?

Hi Steve, Thanks for the Info. I tried using Size_is option. Still nor working. Can you give me a working Client Server Code? Thanking you. Arun

Hi, I have an outproc server Executable which exposes an Interface IServicer. IServicer has a Method GetBytArray([in]BYTE* bytArray). This method has to get a Byte array from client and utilise the values of the array. When iam calling this Interface method from client by passing a byte array of size 10, at the server iam only able to access the first element of the array. i.e only first element of the array is marshalled from client to Server. This is happening only in the case of OUTPROC Servers. How can i access the entire BYTE array without utilising VARIANT or SAFEARRAY concepts?

Thanks David.. That worked. One more thing. If the dialog is a modeless dialog and if the user goes back to the main frame window and moves the window, the modeless dialog will go out of application. So for this i have added the WM_MOVING event in MainFrame class. void CMainFrame::OnMoving(UINT fwSide, LPRECT pRect) { //CFrameWnd::OnMoving(fwSide, pRect); HWND hWnd = pDlg->GetSafeHwnd(); RECT rc; RECT* pRc=&rc; rc.left=rc.top=rc.right=rc.bottom=0; LRESULT result = ::SendMessage(hWnd, WM_MOVING, (WPARAM)fwSide, (LPARAM)&rc); } and modified the WM_MOVING handler of Modeless Dialog as below. void CModelessDlg::OnMoving(UINT fwSide, LPRECT pRect) { CDialog::OnMoving(fwSide, pRect); CRect rcParent; if(pRect->right==0) //Calin from MainFrame GetWindowRect(pRect); GetOwner()->GetWindowRect(rcParent); // keep the child's left edge inside the parent's right edge pRect->left = min(pRect->left, rcParent.right - m_nWidth); // keep the child's left edge inside the parent's left edge pRect->left = max(pRect->left, rcParent.left); // keep the child's top edge inside the parent's bottom edge pRect->top = min(pRect->top, rcParent.bottom - m_nHeight); // keep the child's top edge inside the parent's top edge pRect->top = max(pRect->top, rcParent.top); // keep the child's right edge inside the parent's right edge pRect->right = min(pRect->right, rcParent.right); // keep the child's right edge inside the parent's left edge pRect->right = max(pRect->right, rcParent.left + m_nWidth); // keep the child's bottom edge inside the parent's bottom edge pRect->bottom = min(pRect->bottom, rcParent.bottom); // keep the child's bottom edge inside the parent's top edge pRect->bottom = max(pRect->bottom, rcParent.top + m_nHeight); if((rcParent.Width() < pRect->right - pRect->left) || (rcParent.Height() < pRect->bottom - pRect->top)) { this->ShowWindow(SW_HIDE); } else this->ShowWindow(SW_SHOW); this->MoveWindow(pRect); //Added by Arun } Once again Thanks a lot David..... :)

Nop. This does not work for me. Any ways thanks for the help. :)

Hi Micheal, Thanks for your reply. How to embed the CDialog into the CFrameWnd in SDI application so that my requirement is accomplished. I mean a bit of code. Please help me. :)

Hi enhzflep, Yep.I have implemented the OnMove(..) solution for this. But seriously searching for some direct method like inheriting some poperties of CView which will make the dialog to be constrained to be with in application. Hope any one knows the better solution. Thanks Mate.

Hi Richard, As advised I have limited the size to be with in the application. But, the problem comes when user is trying to move the dialog. It goes out of application boundaries. I want a functionality similar to CView child objects which stay with in the MainFrame.

Hi Friends, I have an interesting question for all. How can i restrict a dialog box(Modal or modeless) to stay within the application boundaries? Just like CView derived objects will not move out of application. I know we can do it with OnMove(..) event handling. But, i wanted to know whether there are any other direct means like by setting some properties to CDialog class. Please help me with this. Regards, K ARUN KUMAR
