CRuntimeClass* pRuntimeClass = RUNTIME_CLASS( CMyClass );
CObject* pObject = pRuntimeClass->CreateObject();
ASSERT( pObject->IsKindOf( RUNTIME_CLASS( CMyClass ) ) );
the above is an sample for creating object dynamically. But the same thing can be done easily like this also :
CObject *pObject = new CMyClass();
So can you tell me the advantage of dynamic creation using CRuntimeClass ?
Thanks for your time

At the "external effects" thay are equivalent, but what you do in your second sentence is not a "dynamic creation": it is a static creation (you know the type) of a dynamic object (is allocated runtime "on demand").
Now, exend your view and imagine your code to be inside a function that has to create an "object" whose type cannot be known to you at the moment of writing the function.
Your
CRuntimeClass* pRuntimeClass = RUNTIME_CLASS( CMyClass );
CObject* pObject = pRuntimeClass->CreateObject();
ASSERT( pObject->IsKindOf( RUNTIME_CLASS( CMyClass ) ) );
can loose its first line and take CRuntimeClass* pRuntimeClass as a function paramenter.
But your
CObject *pObject = new CMyClass();
cannot.
It can only create a CMyClass.
This is mostly used in MFC serialization of pointers: the runtime class classname is saved, and, on load, the CreateObject function called.

I think you are a newbie round here..first of all *don't* post in caps...it is considered as shouting...and is a *very* bad netiquette and considered rude.
Also if you want to have the solution, you would have to work hard...no one will deliver it ready-made to your mail. We can help you out, but you have to ask the right way....

 hi all
how can i render a text with halo effect using win32 GDI functions
need help urgent!!!
regards
pradish

What do you mean by the 'halo effect' exactly?
You might look at DrawFocusRect for guidance on the common 'dotted rectangle' surrounding selected items.
The DrawFocusRect function draws a rectangle in the style used to indicate that the rectangle has the focus.

I presume you are talking about something similar to the blue "glow" that you get on OS X edit fields?
One thing you could do is to customize the WM_NCPAINT message. This allows you to paint in the "border" region, i.e. the non client area, of a control. You could customize the size of the non client area and then with WM_NCPAINT you could draw you own glow effect, however you choose to do that.
If you want to actually render the *text* with a halo, win32 GDI has no functions that do this. You might look into GDI++, or some other alternate library like AGG[^] to help out with that.

I have seen various people using various macros for the same purpose, and that confuses some people
Should I use _T or TEXT?
Should I use _TCHAR or TCHAR?
Jeffrey Richter uses TEXT and TCHAR in his book, but at all other places I have seen _T and _TCHAR.

_T() allow you to be unicode/ansii independant...
so, if you just - one day - #define _UNICODE, if you use the _T() macro, you won't have to change anything in your code, and it will support unicode.
of course, if you do so, use TCHAR instead of char...

It's upto you what to use, as they are same, i.e. nothing difference between them

I have this piece of code:
<br />
result = RegOpenKeyEx(hkey, registrykey, 0,KEY_SET_VALUE ,&key);<br />
where registrykey is a _TCHAR *. This line compiles fine with _MBCS defined, but when I change it to _UNICODE, I get this error:
error C2664: 'RegOpenKeyExA' : cannot convert parameter 2 from 'unsigned short [512]' to 'const char *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
Any idea why 'RegOpenKeyEx' is getting resolved to 'RegOpenKeyExA' when _UNICODE is defined? Can we fix this problem without explicit casting? Thanks in advance.

Where did you define _UNICODE? It needs to be defined for all the files (at the project level, for example)
Or maybe you didn't re-create your pre-compiled headers?
'RegOpenKeyEx' getting resolved to 'RegOpenKeyExA' means _UNICODE wasn't defined at the time the compiler found its declaration.

Yeah, I defined it in the project settings. I just changed _MBCS to _UNICODE.

I changed 'Automatic use of precompiled headers' to 'dont use precompiled headers', and got the same errors.

Note that _TCHAR is getting resolved to unsigned short, I am wondering whats going wrong with RegOpenKeyEx...

Try defining UNICODE (with no leading underscore) too. It seems like _UNICODE affects MFC headers, while UNICODE affects Win32 API headers.

Right, I just noticed that that RegOpenKeyEx resolves to RegOpenKeyExW when UNICODE is defined, and not when _UNICODE is defined. I couldnt locate if UNICODE is automatically defined when _UNICODE is defined. So I now changed _UNICODE to UNICODE in the project settings, now tchar.h doesnt seem to know about UNICODE:
error C2664: 'RegOpenKeyExW' : cannot convert parameter 2 from 'char [512]' to 'const unsigned short *'
