I need to do it programmatically for 2 RichEdit's. When I press VK_DOWN in one the second shold scroll down too. How is it done?

If you are using Document/View and both windows are displaying the same document then you could use a document member variable to keep track of which line is displayed at the top of the window and then just call UpdateAll() when that value changes in one of your views.

I use nothing in MFC. I write an ATL component with 2 RichEdits so I need a way to do it in pure WinAPI.

You still have 2 options: 1) Maintain a window independent (scroll) position of the top left courner some where and then when the position changes in one window just invalidate the other window, or 2) When you you recieve a movement command in one window post the same message to the other window (this might require some translation or your part, but it shouldn't at the message should be in client coordinates).
Good Luck!

is there a way to use interrupts of parallel port directly in c++ .
i.e without using windows API CreateFile(),etc.

Depending on the OS, you may or may not (HAL) have direct access to the hardware.

Can anyone tell me if it is possible to use a controller
in Visual C++ to show a HTML page, like a web browser would
show it?
My application should show a html page, hopefully with fully
working links.
Hope someone can tell me or direct me to a tutorial!
thanx

Is it possible to project a point to a line in 3d ?
I have a point, a line ( vector ), I'd like to project the point to the line to create a triangle out of the 3 points.
here's a picture of what I' trying to explain.

I want to add a button to the menu to clear the recent file list but don't know how to. Does anyone know the function or at least a way. Thank you.

Hi,
in your application class create a handler for the menu to clear the recent file list.
in that handler do:
<br />
if( m_pRecentFileList->GetSize() <= 0 )
<br />
for(int i = m_pRecentFileList->GetSize() - 1; i>=0; i--<br />
{ m_pRecentFileList->Remove(i);<br />
}<br />
m_pRecentFileList is a protected member of the CWinApp class
That should do.

Hi,
Does anyone know hows to send SMS messages to mobile phones using VC++?

Not sure if it can be done without the use of some digital signal equipment, its probably easier to make your own mobile phone.

It is pretty easy if the phone company provides an email gateway for this. I got my phone from telus, and all i have to do is send an email to <my phone number>@msg.telus.net. I would think most phone companies would provide a similiar service. I would not know how to send the message directly to the phone though.

At my company, we've got a client/server that requires user-names for security reasons. Some users can access more data than others. It runs on our company LAN, and is only used in-house. We use raw TCP/IP to do all of our communication (no SOAP or fancy XML stuff).
We've got a complex network with several domains and centrally administered user accounts, so we thought functions like GetUserName() are enough to know who we're dealing with (the app sends the name over with each request). Turns out we were wrong.
We have many users who go home and use Cisco VPN to run our app. Many of them run Windows98/ME, or XP without logging into our company domain. They'll have usernames like "Frank" instead of "FPrisco", and worse, they can make up any user name they want and pretend to be anyone.
I've looked into the Win32 security apis, and my god they are complicated. What we want to do is avoid jostling local users who have legitamately logged into the PC, vs people who are using non-authenticated logins on crappy OSes.
I have two specific questions:
1) There do not seem to be any standard OS dialog for handling a domain login (gathering the username, password, and domain-name and then doing the authenticate), a'la what you see in explorer when you try to access shares you are not authenticated for. Is there such a thing? Do all apps that can do domain logins re-implement this dialog?
2) In the absence of any library code to do (1), I've figured out how to determine whether a username/domain/password combinationis legitamate. Once I have a valid login, is there anyway to "set" this into the user's environment, so they are not-reprompted every time they start up our app, or use other network services that require a domain login?
Any help would be appreciated.

Well, so far the best bit information I've found is the
SSPI Authentication Sample on MSDN. SSPI lets me take a username, password, and domain, and see if its valid. It does all the work finding & contacting the domain servers. I haven't been able to 'store' a successful login, or find any sort of standard dialog for handling the login, but for the moment this SSPI function is enough.
One thing I am having trouble with though, is getting the current domain on Win98. There is the LookupAccountName API function, which is not supported on Win9x. I just need to know which domain the user has logged into. Google searches aren't turning up much, other than affirmation hat LookAccountName sucks.

hwnd desktop = GetDesktopWindow(VOID);
RECT myrect;
GetWindowRect(desktop, &myrect);
This will load 'myrect' with the size of the desktop window. I'm not sure how it will behave on a multi-screen setup. You might get the size of the first display's desktop only, or maybe the size of the ENTIRE desktop. There are some functions to enumerate the actual displays, but I don't remember any of the details.
