yes, ok, i like to know for the future how to use this in programming,
and my current app is multithreaded, maybe i can make this to multicore app...when i know more about multicore programming..
regards

There's no such thing as "multicore programming" at application level. The operating system handles the details of multiple processors, multiple cores, hyperthreading, etc. If your application is multithreaded, the OS takes care of scheduling it on whatever execution units are available.

Not really a big problem since I could just rename my function, but nontheless, I would like to know how to correctly deal with this.
I have a class with a member function:
virtual HWND CreateWindow( DWORD dwStyle, HWND hWndParent );
No prizes for guessing what the derived class should do 
Upon compile, it clashes with the CreateWindow macro giving me an error:
warning C4003: not enough actual parameters for macro 'CreateWindowW'<br />
error C2059: syntax error : 'constant'
Would somebody be kind enough to help me out with this as I really really want to keep that function name.

Why?
|
|
|
|

I think that after un-defining the definition, the original CreateWindow functions from Windows API will not be more available inside the implementation of the other CreateWindow member.
|
|
|
|
|
Actually the API is still available, though you have to call the proper one
(you can also define by yoursef a macro to wrap the standard/unicode issue).

My 4mb connection is running at 2k again today 
I thought about the #undef method, but I would then need to define it again after the function. Redefining involves checking the UNICODE and using the correct function, in doing so what's to say the origional macro will not change after a few months.
For now I have simply renamed the function to GetWindow(), but this is confusing within my personal naming schemes.
You also asked for a code sample of how it's called:
m_hWnd = GetWindow( dwStyle, hParent );
if ( ! m_hWnd )
throw _T("Unable to create window");
BOOL bSuccess = FALSE;
bSuccess = SetWindowPos(m_hWnd,NULL,uLeft,uTop,uWidth,uHeight,SWP_NOZORDER|SWP_NOSENDCHANGING);
The derived class would then call the orgional CreateWindow() macro/function to creat a certain type of window ( window class ) and return it's handle.

My personnel belief, always try not to use Actual Window api name in your classes.. as it might confused other programmer.... here GetWindow can again create problem... better change it name to CreateMyWindow.. etc..

Actually the problem is due to circular macro.
i.e. CreateWindow expands to CreateWindowW (on UNICODE). Again, is CreateWindowW is macro, which is defined as,
#define CreateWindowW(lpClassName, lpWindowName, dwStyle, x, y,\
nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)\
CreateWindowExW(0L, lpClassName, lpWindowName, dwStyle, x, y,\
nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)
It expects 11 params, against 2 provided.
Hence , there is macro mismatch, and error.
You can use ,
#ifdef CreateWindow
#undef CreateWindow
#endif
But, this will prevent you from using this macro elsewhere in application.

Short answer: you can't.
Because "CreateWindow" is a macro, the replacement of "CreateWindow" with "CreateWindowA/W" is done by the preprocessor, without regard to scopes or namespaces. This is why, for example, the MFC and ATL methods are called Create() and not CreateWindow()

Hi,
I suggest reading RFC3207 for instructions on how to initiate secure transfer with TLS encryption.
Earlier version of this extension is RFC2487.
Hope that helps,
Regards

How to fit the current view with in the resized window?gluProject is not working.Some times the figure is coming correctly in the resized window.Sometimes not.Plz help.....

Do you intend to ask that you've got controls within a window and you want those controls to be auaomatically resized to fit within the window after resize?

Not controls.Within the window i have a 2d/3d diagram.I want to fit that.I can zoom in/out the diagram.But if i do as follows:
-window size is maximum.
-zoom the diagram in the window.
-the diagram extent goes out of the current window border.
-resize the window to a smaller size than the current one.
that is not happening.A larger portion gets cutoff.
-Now,the view should be same as that of the original, still fit in the current window(different size).

I do not know if I am right, but I think you have an image within a window and you want to adjust the size of the image dynamically to fit within the window. All you need is to resize the image when the window size is adjusted. Calculate the window size after resize and draw your image in the memory according to the window size and then put it into the window.
