If you'll change the title to "Hello World", I'm sure the project will be much easier.

Did you have any question?

Help with what? Also, pick a more descriptive subject line, instead of "Dear all"...

Hi,
I need an algorithm that fits an ellipse to x, y points. I looked around online but there is nothing written in C++. Even a methodology to achieve a fit will be good enough and I will be able to write the code.
I also have the center position and all the raw data points. I need a best fit ellipse to it.
Any help would be greatly appreicated.
Thanks

If you don't mind playing with matrices, here's[^] a "numerically stable non-iterative algorithm for fitting an ellipse to a set of data points" (method of least squares).

Hi,
I saw this from my searching online, but the problem is none of this makes sense to me.
Is there a step by step procedure to solve this problem.
Thanks

All,
Is there an easy way, in an MFC application, to launch and automatically play a .WMV file? I don't want to open Windows Media Player, but instead have this video play inside my application.
Thanks in advance.

You can embedd the media player inside your app as a control. My memory is rusty on how complex this is to do in C++, although I know it's trivial in C#, if you can handle a .NET dependancy, you could use the .NET control, although it just wraps WMP, so there's no reason you'd need to.

IMO the easiest way to play a WMV is to use DirectShow[^].
The SDK has enough sample code to do a player with minimal effort.
If you want to work with the files, the Windows Media Format SDK is a great
resource. See Windows Media Downloads[^].

I have since tried this and was able to load the video, but the playback is VERY choppy. It seems that it pauses about once a second as if it caching more of the video.
Any suggestions as to why this happens?

Could you load other formats like avi or Mpeg?

Hi,
I have a Windows service that I had running yesterday, but today I can't get it to start. I have gone back to my old code that ran yesterday, but it still doesn't start. How can I get an error code that will give me some hint of what the problem is? The failing code is shown below:
<br />
if( ::StartService(schService, 0, 0) ) <br />
{<br />
Sleep(1000);<br />
<br />
while( ::QueryServiceStatus(schService, &m_ssStatus) ) <br />
{<br />
if( m_ssStatus.dwCurrentState == SERVICE_START_PENDING ) <br />
{<br />
TRACE( "." ); THIS LOOP NEVER EXITS, SO I CAN'T GET AN ERROR CODE<br />
Sleep( 1000 );<br />
}<br />
else<br />
break; <br />
}<br />
I found an event in the application event log with the following description, but I don't know what it means:
The description for Event ID ( 0 ) in Source ( AutoFileHandler ) cannot be found. The local computer may not have the necessary registry information or message DLL files to
display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following
information is part of the event: Service installed.
Can anybody help me with this?
Any help greatly appreciated.

If StartService() is failing, have you tried calling GetLastError() to find out why?

When I try to start it from the services panel, it just hangs for 2 or 3 minutes before the system shows a dialog indicating that the service failed to start.
StartService() doesn't fail, nor does QueryServiceStatus(). QueryServiceStatus() puts zeros in the exit code variables dwWin32ExitCode and dwServiceSpecificExitCode of the SERVICE_STATUS struct. It just never exits the loop waiting for the m_ssStatus.dwCurrentState to change from SERVICE_START_PENDING. GetLastError() always returns 0.

Are you sure your service application is starting correctly
(particularly, SetServiceStatus() to SERVICE_RUNNING)?
Have you tried attaching to the service process with the debugger to see
what's going on?

Yes, I have tried starting the service from the services snapin, then attaching the debugger. It is always stuck in this loop waiting for a change in the current state. I have also stepped into the code from the Winmain entrance and it goes directly to this wait loop. However, I will have to wait until Monday as I can't uninstall the service remotely in order to restart it and I am not at my workstation. So I will pursue this then.
Thanks for your help.

Hi guys. I need to put a web browser control into an application. I don't care what language I do it in, but I want to get events when a DOM event fires ( such as a mouseover or a click on a link ), and I want to get an event that tells me they are about to fire, which allows me to cancel the event. Is this even possible ?
