asserts are using only for debug pupose.
suppose if ur buffer getting NULL a endless loop or a lengthy looop, u need not to debug the each loops.
if an assertion occrurs then it will show "This expression failed at this line of source code" then u can trace and correct the bug.
never put ur logic inside the assert macro. because it wont work in release build.
in release build VERIFY macro will satisfy u with the same functionality of assert offer.
I think asserts and exception standing at different areas of erro handling.
We are used to compare with strctured error handling and the normal error handling we are used to follow in "C".
it is depends on ur system to select which is suitable. each mechanism has its own advantages and disadvantages.

I've got an app created as an ANSI Build and want to use a few controls such as an Edit control (CEdit) as Unicode, if running on Win2K or later. I don't want to build the app as Unicode at this time, as I want to support W98 and don't want to have to use the MS W98 Unicode Layer.
I've pretty much spent the day Google'ing and reading and it seems doable, but I've yet to find any concrete info on how. One idea is to provide my own implementation of CWnd::CreateEx() that calls CreateWindowExW() if we are running on W2K/XP etc. but I suspect there is more to it than that.
Has anyone done this or have any suggestions? Mucho thanks in advance.

If the app itself is unicode unaware, then how do you expect a child window of the app to handle unicode? You will have to do a unicode build to make the app work with unicode as far as I know.

In case if you did it, please post a reply here and I am very much interested to know how it is.

What better than these samples...
MTGDI
MTMDI
MTRECALC
MUTEXES Search MSDN with these keywords to get the appropriate samples.

IMO, I never liked Threading Sample Provided by MSDN... The article by Mr Joseph, whoes link is mentioned by WhiteSky is one of the best article for learning multithreading programming.

I specially liked the sample MTGDI. These samples are a bit hard to understand but once you get a hang of it you are on a ball.

Of course someone didn't like the suggestions that were given. I guess that is what voting is all about.

m_wndSplitter3.CreateStatic(&m_wndSplitter2,2,1,
m_wndSplitter2.IdFromRowCol(0,1));
m_wndSplitter3.CreateView(0,0,RUNTIMECLASS(CMyView),pContext);

Check the call stack to see which statement of your file caused this error.

I am not getting any error When i wrote
m_wndSplitter3.CreateStatic(&m_wndSplitter2,2,1,
m_wndSplitter2.IdFromRowCol(0,1));
m_wndSplitter3.CreateView(0,0,RUNTIMECLASS(CMyView),pContext);
in OnCreateClient().
I am getting the exception only when i wrote the above statements in amy own function. I have written
int id=m_wndSplitter2.IdFromRowCol(0,1);
m_wndSplitter2.DeleteView(0,1);
m_wndSplitter3.CreateStatic(&m_wndSplitter2,2,1,id);
m_wndSplitter3.CreateView(0,0,RUNTIMECLASS(CMyView),pContext);
m_wndSplitter3.CreateView(1,0,RUNTIMECLASS(CMyView),pContext);
Can't we create the splitter window in a function other than
OnCreateClient()?
I am getting the exception at
POSITION CPtrList::Find(......)
{
ASSERT_VALID(this);
CNode* pNode=(CNode*)startAfter;
if(pNode==NULL)
{
pNode= m_pNodeHead;====>here i am getting the exception
}
.......
...........
}
This code is present in LIST_P.cpp.
When i debug the program, i am getting the exception at
mov ezx,dword ptr [edx+4]
I don't know why i am getting this exxception.
can anybody tell me why i am getting this exception 
Thanks in advance.

I know the exception is in the file LIST_P.cpp. But it could be caused by one or more statements in your file i.e. in the OnCreateClient function. So that's why I told you take a look at the call stack. Try to comment out all statements in the OnCreateClient. Then Uncomment all the others one by one. Trying the find out who is the real culprit.

I did what u told me to do.But i am not at all getting any exception because of the code in OnCreateClient(). I am getting th eexception only when i wrote the code in my function. I am not able to understand the reason for this. Can i create the splitter window in a function other than OncreateClient()???

AFAIK No! OnCreateClient is the function that is called during the creation of the client area. Hence you must create your splitter there.

Hello!
I came accross the article http://www.codeproject.com/tips/dirclean.asp[^] which is about some handy utility. Shell extension DLL is provided. Can somebody please tell me how to register this shell extension trough console maybe? I really don't want to learn about shell extensions right now. All I want, is to use this utility.
Best regards,
Rostfrei

Is it working with regsvr32 ? Start Menu -> Run and type regsvr32 YourDll.dll (where YourDll.dll is the dll you want to register). This dll has to be in the system32 directory (or you have to specify its path also).

I'm created an dll (statically linked). Included this
dll lib and Header file in to my (test file folder).
But the compilation ends with an error undeclared
identifier Testdll. (Testdll, this function name was exported in static dll file)
You only have to do a very few things right in your life so long as you don't do too many things wrong.

Can you be more specific ?
A statically linked dll doesn't exist, maybe you are speaking about implicit linking (you don't use LoadLibrary and GetProcAddress but you have a header file and a lib file).
Please, when you have an error message, post it completely and explain if it's a compiler or linker error.
I suppose you didn't add the library file in the project settings ? That may be the problem.

It Seems like MFC DLL linkage problem, Could you change you DLL COnfiguration from Statically linked DLL To MFC Shared DLL and then perform same task!
