Hi Steve, That was indeed very helpful. I used plain sockets and got this to work. Thanks a TON!!! Jugs "A robust program is resistant to errors -- it either works correctly, or it does not work at all; whereas a fault tolerant program must actually recover from errors."

Hi Jon, You were right. I was not marshalling the interface across apartment boundaries. I used CoMarshalInterThreadInterfaceInStream and CoGetInterfaceAndReleaseStream methods and was successfull. Thanks for the support.

Is your background simple enough that you could just fill it with a background color? pDC->FillSolidRect(rect, RGB(255,0,0)); "When you know you're going to eat crow, it's best to eat it while it's still warm." - Reader's Digest

You can get the HWND of your applications main window... there are several ways to get HWND, like get HWND using "caption" or "class name" for window with the help of FindWindow API... Once you get the HWND you can very well use "SendMessage" or "PostMessage" for further communication... All these things would go inside your BHO, Office addin or so... >>Also Is it possible to create a Singleton Automation server ? sorry no idea about the Singleton automation server...

Hi Jugs, OK, so you have some COM servers (BHOs, MsOffice AddIns etc) and some clients (IE, MsOffice apps) that creates these servers. And... you are talking about a new COM server (the GUI app) where the earlier mentioned servers are clients, right? Let me know if I'm way off And... you need EventSinks in your BHOs and AddIns... Why? Don't we have a design problem here? Who is the client/consumer and who is the server/provider? Do you actually intend to control your clients from the GUI app server? If not; what is the purpose of the event sinks? I don't know what you want to do with your GUI app, which means that your design may be relevant even if I find it suspicious. Isn't the GUI app some kind of a logging application? If so; how about using a UDP port in your GUI app (localhost) and send logging packets to that port from each server? Each server may try to start the GUI app, but the GUI app makes sure that it is the only instance running. Or you could write a service that write logging packets to a file readable from a GUI app. Or some other kind of inter-process communication (WM_COPYDATA?), take your pick. Hope you find some relevans in the above -- Roger -- modified at 10:34 Wednesday 5th October, 2005

Maybe you can use TransparentBlt() in NT. This is an easiest way to paint with a transparent color.

This is an effect of L1 cache. You did not mention the CPU you were using. I assume it was a P4. The L1 access line size is 64 bytes if my memory serves me right. If there are no alignment issues(your compiler often does a good job at this), the smaller size the structure is the more effective for a single L1 line access. Nowadays, people often talk about structure of arrary (SoA), that address such issues....

Since "plain" C++ has no knowledge of databases, recordsets, files, and the like, what you want, AFAIK, is not possible. In order to provide support for these, you'll need a platform-dependent API. I do not know of one for both Windows and UNIX, although it's been 15 years since I worked on a UNIX box so something just might be available. A rich person is not the one who has the most, but the one that needs the least.

Handle each menu item in your CHTMLView derived class like: [...] ON_COMMAND(ID_EDIT_CUT, OnEditCut) ON_COMMAND(ID_EDIT_COPY, OnEditCopy) ON_COMMAND(ID_EDIT_PASTE, OnEditPaste) ON_COMMAND(ID_EDIT_SELECTALL, OnEditSelectAll) [...] Below is the implementation for each member function: void CWebView::OnEditCut() { ExecWB(OLECMDID_CUT, OLECMDEXECOPT_DONTPROMPTUSER, NULL, NULL); } void CWebView::OnEditCopy() { ExecWB(OLECMDID_COPY, OLECMDEXECOPT_DONTPROMPTUSER, NULL, NULL); } void CWebView::OnEditPaste() { ExecWB(OLECMDID_PASTE, OLECMDEXECOPT_DONTPROMPTUSER, NULL, NULL); } void CWebView::OnEditSelectAll() { ExecWB(OLECMDID_SELECTALL, OLECMDEXECOPT_DONTPROMPTUSER, NULL, NULL); } I got this code from an article somewhere, but unfortunately, I can't find where the article is again. Anyway, this should help you out. :) Happy Programming! WWW::CodeProject::BNEACETP

Just found this "Using Scintilla for syntax coloring in MFC" at codeproject. The article recomends going to www.scintilla.org for information on regular expressions, auto-complete, etc... Good Luck! INTP

Thanks for the effort ABean. But I forgot to mention one thing, I am looking for sourec code in VC++. If you know any, pl. help me by posting the URL.
