Hai!
This is a silly doubt?
is there any function in VC++ to extract a substring :
for ex.
CString str = "My name is Vicky";
CString substr;
substr = CSTRINGFUNCTION (str, 11, 5);
the sustr will contain "Vicky".
Is there any direct function or i have take a loop and pick up each character??
Thanks!

If your substring is on the right, you can use CString::Right[^]. If it this in the middle, you can use CString::Mid[^].
By the way, looking at the documentation can be very helpfull sometimes...

CString::Mid
Enjoy!

To
substr = str.Mid(11, 5);.

We are Deriving a class from CGXGridView from stingray.
I want to select multiple rows and update the information in that.
Is there any method to Find First Row and Last Row in Multiple selection in the Grid.
Thanks,

can anyone tell me about difference between Events and Functions ,is there any difference regarding their processing
|
|
|
|

Events ? In which context ? This is such a generic word that it is used for a lot of different things. Are you talking about windows messages ?
|

I dont know why you asked this question but see here[^] for event.

As both Cédric and Hamid suggested, your question is not very clear what you mean regarding the concept of "events".
But in my opinion the only meaning of events where it makes sense to be compared to functions is in the sense of windows messages. If you mean something else you can stop reading here. 
Windows is a so called "event-driven" operating system.
This means that every action will generate an event, which in windows is represented by a message.
If you wish to react on a certain action, you write a message handler for the message; e.g if you want to do something when the user double clicks the left button of the mouse, you write a message handler for the WM_LBUTTONDBLCLK message.
Regarding "functions" you must of course write functions and call them in order to do the things you want. But this also means that if you're spending a lot of time in a function call chain, the user will find the user interface inresponsive because you are not handling messages. To prevent this unpleasant user experience, it's common to use worker threads that run in the background performing lengthy operations.

Yes and no ... it mostly depend on the language and on the programming model.
The conceptual difference is that a "function" is something you call to get a work to be done for you.
An event is something you call to inform "someone who may listen" that it may have some work to do for itself.
Then, since everything has to work on a Von Neumann machine, events are "handled" by functions (but "aren't" themselves functions).
In more "real life": a function call is a capability you expose to me, that I can call: like me telling you "please do this calculation" (And Im'interested in the result).
An event is a capability I expose to let you able to do your job, like "please be informed that a mail has arrived".
I'm not directly interested in what you can do with it. Just know you wish to be informed about.
Just note how in both the example, the active subject (the one that "owns" the timing) is always "me". If you invert, than event and function also invert their role.

I don't think there is a function to set back ground image for a tree control. How ever you can draw an image by deriving a class from CTreeCtrl and the draw the image by overriding the WM_ERASEBKGND message.

After decades of fun we now have to stop using MFC in the project.
How do I get this to work? I want a simple solution, because I have this about 1000 times in the code. I tried those answers which seemed obvious to me, but it does not compile.
const char CODE_N = 'N';
string SK::getCode() const // was CString
{
return CODE_N;
}
1>..\path\SK.cpp(1423) : error C2440: 'initializing' : cannot convert from 'const char' to 'std::basic_string<_Elem,_Traits,_Ax>'

Thankyou for your quick reply.
I realise I had hit on one of the few const char definitions which only has one character. Those with more than one worked fine the way it was.

I used the CWnd::GetClientRect function but it returns a rect with top=0,bottom=0,left=0,right=0,the dialog is not minimized why it happens

Are you sure you'd able to see the Window? From Which function you're calling this ? Have you declared any variables having same name in different scope and referring false one? Can you post the snippet?

Depends what you mean by "it is possible" . You can't make the same executable run on different platform, because the format is different for each of the platform. However, if you stick to pure standard C++, then the only thing you will have to do is recompile your code for each of the platform using a different compiler.
But of course, you'll probably need more than just standard C++ and there are some cross-platform GUI libraries that exist which allow you to write cross-platform code. Look for instance at wxWidgets[^].

C/C++ is general purpose language. Even if you decide to do that with Pure C/C++, you will have to get support from Operating system.
What about trying QT?[^]
