Exactly what type of communication do you need to perform?
Can you give an example?

CScrollView is a derived class of MFC supporting scroll.When size of document is bigger than size ofviewport,CScrollView will display scroll automatially.
How can Hide the scrollbar(s) and i can still scroll the view by such as mousewheel events in this case.
Is there any derived class of Cview to complete the same function(supporting scroll but not showing the scrollbar).

Why in the world would you want to contradict standard Windows usability and provide scrolling without a scrollbar? Why would your users want to re-learn how to scroll, just for your application? Then, have to deal with different mouse gestures as they switch between your applications and all other Windows applications?
What happens if your users don't have mouse with a scroll wheel?
CScrollView-derived views cannot simply have their scroll bars "hidden"; they are integral to the window. You would probably have to override the non-client size calculations and drawing.

In fact, i want to own a style like ACDsee viewer, users can move the content by drag mouse, but not by scroll the scrollbars. In my derived class of CScrollView, i have complete for it, but i cann't get rid of the scrollbars, it ocuppy the area of use's content.

Then just use CView and handle all the scrolling yourself.

Is there any derived class from CView in existence?

CView is derived from CWnd and is the base class of CScrollView and CCtrlView. Since what you are asking for is non-standard behaviour I doubt there is a readily available class that does what you want, but there might be if you search long and hard enough. You said you had it working with CScrollView, just the scroll bars were giving you trouble. It shouldn't be too difficult to derive a class from CView that does what you want. Just take the parts from CScrollView that you can use, and ignore or modify the parts you can't use.

Hi,
I have a ListView in which I have used WM_NCCALCSIZE to give me an area at the top where I can draw my own info (above the header). This is fine except that it messes up the vertical scrolling. The last list item (in report view) doesn't appear. (My additional NC area is about 18 pixels high, which is about the height of one item.)
It seems that the ListView still thinks its client area is the original size, and so does not allow scrolling down as far as the last line. I have tried using SetScrollInfo to increase its max scroll point, and this works in that I can click down and see the last line appear, but on releasing the mouse, it jumps back up a line, and reverts to the original scroll-bar behaviour.
Does anyone have any ideas on how I can fix this? (If I apply the same code to other types of control they work fine, it's just listviews that don't.)
Thanks,
Paul.

Just a wild guess here. Could it be that the list view expects to only have a CHeaderCtrl at the top, and adjusts its scrolling only based on the header control. How about making the CHeaderCtrl ownerdraw and adding the extra space to the header instead of the list control itself?

I think it must be something to do with that, though turning off the header doesn't make it any better.
You can try it easily by subclassing a ListView control, then handling WM_NCCALCSIZE and adding something like
lpncsp->rgrc[0].top += 20;
Now, add a load of items to the list, and you will see that the vertical scroll-bar doesn't allow you to scroll right to the bottom of the client area. The bottom items get clipped.
I can't find any way of telling the ListView how big to consider its client area to be.
The closest I have to a solution is to fiddle the scroll bars on scrolling:
SCROLLINFO si = { sizeof(si), SIF_RANGE };
m_pList->GetScrollInfo(SB_VERT, &si);
si.nMax = m_pList->SendMessage(LVM_GETITEMCOUNT);
m_pList->SetScrollInfo(SB_VERT, &si);
This allows me to scroll to the bottom, and shows me the bottom item when scrolling, but on releasing the mouse button it jumps back up one notch.
I know you like a challenge, and will no doubt find me a solution!

Hi all,
I want to get through a proxy server which needs NTLM authentication.

2) How to set up the headers
I am using WinInet (CInternetSession).
Thanks!

There are few problems with the code.
1. You are trying to pass the parameter along with the exe name, which is not suggested.
so make two strings like :
string sFile(_T("regsvr32"));
string sParam(_T("/u \"C:\\Program Files\\Demo\\Components\\demo.dll\""));
2. Also note the dll path wrapped with double quote above.
Now call
::ShellExecute(hWnd,_T("open"),sFile.c_str(),sParam.c_str(),0,SW_SHOW);
