Hi to All,
How can I make my Exe as a service using VC++. that service should appear in Services of Administrator tools and that should start when the system is boot up and should appear in system tray icon to tell that it is started. Can anybody help in this regard.
Thanks in advance.

I have used DialogBar in my application on which i have few Dropdown listbox,
i dynamically create and destroy the DlgBar depending the option selected
by the user.
The problem is that the DlgBar is not visible when i creat it ,
i tried
AfxGetMainWnd()->RedrawWindow();
AfxGetMainWnd()->Invalidate (TRUE);
But it donot work .............
When i minimise and maximise the application then i can see the DlgBar
by using this code.
AfxGetMainWnd()->ShowWindow(SW_MINIMIZE);
AfxGetMainWnd()->ShowWindow(SW_MAXIMIZE);
Can anyone point out what i am missing .

I'll assume you mean a control bar.
You could try: CFrameWnd::ShowControlBar(CControlBar* pBar, BOOL bShow, BOOL bDelay);
INTP
Every thing is relative...

Whoops!
A Dialog bar is derived from a control bar, so ShowControlBar is probably the corrent function to use.

error C2039: 'ShowControlBar' : is not a member of 'CDialogBar'
its not the member of the DlgBar class
Can u tell me the way that will Repaint the
Main window in any conditon .
I think i will have to try that because when i
minmise and maxime the mainwindow the dlgbar
show its presence .
AfxGetMainWnd()->RedrawWindow();
AfxGetMainWnd()->Invalidate (TRUE);
AfxGetMainWnd()->UpdateWindow ();
this->PostMessage (WM_ERASEBKGND ); this dont work
I have already tried this things;
Thank you

ShowControlBar() is a member of CFrameWnd from which your main frame window is derived. Therefore you would probably call it like this:
AfxGetMainWnd()->ShowControlBar((CControlBar*)pMyDlgBar,TRUE,0);
Why? Because CDialogBar is derived from CControlBar.

First should call Invalidate() before you call RedrawWindow().
AfxGetMainWnd()->Invalidate();
AfxGetMainWnd()->RedrawWindow();
When dealing with control bars and dialog bars this might help:
AfxGetMainWnd()->RecalcLayout();

Thank you
AfxGetMainWnd()->ShowControlBar((CControlBar*)pMyDlgBar,TRUE,0);
it solved my problem by setting the second parameter TRUE/FALSE
we can change the visibility of the Dlgbar
ok

You're question doesn't have enough information to make sense, or expect a usefull answer.
You posted about 50 lines of code but the error is on the 3rd line - why do we need to see the rest at this point.
There are many things that could be wrong that have nothing to do with the code.
You should check that the database is setup right and explain what you have checked.

Probably there is some error with
the OLE DB you are using.
Did u find out that the connection
is working proper .
Ther is one more method CEnumerator which
prompts the user with a locator dialog box.
from wich u can select ur connection and
try opening the database.

Actually He has used this code in three more places.
And I am mimicing his code.I have gone through his code
in and out.Only what I have sent you that much is inly related to database connectivity. And in same project at other three locations it is working perfectly

Does it? I can't get it to work... 
I'm running the Feb 2003 SDK. It there maybe an update that fixes this?
Thanks!

Not that familiar with OpenGL - but had fun(!) with this type of thing before.
First thing to check is your graphics card. Does it support alpha? If so then check the configuration setup in the control panel. You may also want to check that you have the latest drivers from your manufacturer.
I once spent hours trying to get anti-aliasing working on my laptop's card

using alpha is a combination effort. In otherwords you cannot simply use alpha transparency, you first have to enable it, and also provide a function for method of processing alpha. The whole process is called blending since you are using a source color value, an alpha transparency, a function for combining the two into a new blended color.
Try looking here for an example, it is my personal favorite OpenGL site: NeHe[^]

Is it possible to use alpha with OpenGL??

Thanks a lot, that really helps!
He says "You should SORT THE TRANSPARENT POLYGONS BY DEPTH and draw them AFTER THE ENTIRE SCENE HAS BEEN DRAWN, with the DEPTH BUFFER ENABLED, or you will get incorrect results."
How do I determine the depth of the object? What is the proper function to use to get the distance between the viewpoint and the object?
Thanks,

distance is distance is distance.... You can project the xyz data into viewer references, in which case you will get your depth as a valid number. Or you can just use the old distance formula d=sqrt(deltax*deltax+deltay*deltay+deltaz*deltaz).
however since all you need is a compare and sort, drop the sqrt. The square of the distance won't make one distance shorter than another.
The author is primarily referring to the fact that the programmer often has knowlege of what he is doing that the computer does not. So you can order your logic to provide the computer with an easier time. You generally do not have to depth sort opaque objects, draw them all and let the hardware z-buffer sort them out. So then you are left with your alpha transparent objects. Some of them you may already know their order.
When you have limited knowledge of what you are going to draw and when (or simply providing the power of flexibility), that is when you start getting into game-engines and scene-graphs. If you have n number of objects of unknown type, and unknown complexity as far as alpha-objects, you toss all n-objects onto a scene-graph and issue a scene-graph draw command. The scene-graph-API handles sorting, culling and other tasks that will have to be performed every time you draw (as objects move in relative position to each other and on their own axis -- a plane doing a barrel roll with a transparent glass canopy for example will generate a new z-sort every time).
www.openscenegraph.org[^] has one of many scene graphs (there are a dozen I could rattle off off the top of my head -- google on opengl scenegraph)
www.delta3d.org[^] has one of many gaming engines (based on openscenegraph API for a core), google will again turn up many more (some for a cost).

Well that's the whole thing really. The user can set the camera angle viewpoint anywhere they want, inherently reversing the order of the objects in my scene. So I need a generic way of sorting these objects by calculating the depth from the camera.
I would have liked most to have a general sort for this. I guess there's no OpenGL option I can enable for this, huh?
And what if you don't know (or don't wanna know) why objects are transparent and which are not...? Or what if some objects are partially transparent or have gradient alphas?
