Your document class will contain some sort of buffer to hold the contents of the file. Your view class will render that buffer on the screen/printer.

Hi David thanks for reply.
I am able to open the file in view window but when i close the application and open the txt file than that file is blank. i dont know why.
If you have any article that explain the doc view architecture and splitter window than please send it to me.
Thanks

Is the document class overwriting the file?

Get a book. For your needs, I would recommend "Programming Windows with MFC" from Jeff Prosise.

Create a new dialog-based project. Copy the relevant code to this new project.

Hello evrybody.
I have developed an MFC application, but now I would like to enable people to develop sort of addins to that application.
I do not want to give the source code of my application, rather do the same way as Visual Studio : ie provide developers with an SDK with which they can create addins that can enhence VS.
Is there any detailed way how to do that ? Like an existing application that features the best practises for me how to organize my application internal code, and how to expose its programmable interfaces.. etc
Thank you in advance.

Perhaps you should take a look at Code Project's most popular aricle here[^] as it seems to include extensibilty support. Otherwise I recall an MSDN Magazine article/series from 6+ years ago that dealt with this. You could search up their back catalogue. Most people who do this sort of thing probably end up using COM either directly or in the form of hosting ActiveX controls. I belive there's a standard way to integrate property sheets with COM based plugins but I've never seen an example.
I hope you find what you're looking for.

Good Morning,
I got a small problem...
I use 2 Picture Control boxes. the first box play a stream from my webcam, the second should be overlap the first, and show a grabbed edited frame.
I just use m_webcam.ShowWindow(0) and m_pic.ShowWindow(1).
The Problem is, after i called this, the Picturebox is empty. But when i minimize and maximize the window, the Picture is shown like i expected.
Is there a way to redraw the picturebox??

CWnd::Invalidate is used to force the redrawing ofa certain window or control. If that helps !

Thank you for your awnser. I tried it, but the problem is still the same

I am missing the details of your problem. But it is sure that you must take care in case for video streaming application where usually the redering window is asynchronously updated by a worker thread that fetches the video data, such that if a resize or a certain wm_paint happens on the main UI thread for the rendering window, the last picture is lost unles you do manually persist it each time the worker thread brings it, so to render it in the context of the ONPaint, or the OnDraw or any similar handler executing on the context of the main UI thread.
I encountered this case in many contexts, the first with Windows RTC (videoconferencing)..
Good luck !

Hello everyone,
I am searching information about the number of nodes which B+ tree update/delete/insert operation will modify (e.g. modify the link to the parent or sibling). The expected information I want is, for example, insert operation will change at least 2 but at most 3 nodes.
Unfortunately, I cannot find such proved information and only the basic implementations of B+ tree. Does anyone have any conclusions or reference materials?
thanks in advance,
George

Thanks DavidCrow,
I think the article only mentions the implementation details (in reference section) for insert/delete/update, not no prove or conclusion for the min/max number of nodes which will be changed (if they are still in the tree).
Any comments?
regards,
George

You could always step through the source code.

Thanks DavidCrow,
I just want to find some one sentence conclusion for the # of nodes changed (conclusion I mean somehting like, like # of external nodes are the # of internal nodes + 1 in a binary tree), and reading source code is slow.
regards,
George

George, if you need a formal proof you need to talk to this lady[^] who knows more about b+ trees than the bees themselves.

Thanks Matthew!
Why you refer her, she is the inventor for B+ Tree? 
I just want to have some conclusion like the max/min time complexity of quick sort, I am surprised it is so hard to find and get an answer.

George

Hi all
What is wrong with my function? it keeps crashing when it gets to return.
bool CUpdateServiceModule::DoCheckForProductUpdates(ns1__Update oUpdateCode, RMproduct* prd)
{
iRet = m_pWebServiceSoap->__ns2__DoCheckForProductUpdates(pDoCheckForProductUpdates,pDoCheckForProductUpdatesResponse);
switch(iRet)
{
case SOAP_OK :
{
if(pDoCheckForProductUpdatesResponse->DoCheckForProductUpdatesResult)
{
pDoGetLatestProduct->productName = pDoCheckForProductUpdates->productName;
iRet = m_pWebServiceSoap->__ns2__DoGetLatestProduct(pDoGetLatestProduct,pDoGetLatestProductResponse);
switch(iRet)
{
case SOAP_OK :
{
RMUpdates* update = new RMUpdates;
break;
return true;
}
default:
{
Log(GetSoapError());
}
}
}
}
default:
{
Log(GetSoapError());
}
}
return false;
}
I am getting this error:
Unhandled exception at 0x004970b6 in UpdateService.exe: 0xC0000005:
Access violation reading location 0xcdcdcdd5.
Please Advise
thanks,
Jayjay

are you acquainted with the debugger! if not know it better. may be there is some uninitialized memory that you are using or you may be accessing some out-of-bounds variable.
what happens when you debug?
Somethings seem HARD to do, until we know how to do them.
