Can anyone tell me what is the main purpose of Dll? As we can get the data from Dll, can we put the data in Dll? I am not talking about code, talking about single Dll. If you know about Dll then please share your knowledge..

Dll is nothing but a reusable code.. its a dead thing it need to invoke from some where ..
by it self DLL cant do anything.
dll can be in any language that supports Pointer Functionality.
Dll is used to process the data
Dll is used to apply Business logic
Dll can be called from any place.
can you please specify what exactly you are looking here in some specific manner???

Consider you know some function that can be helpful to other programmers and, they are ready to pay you for it, so how would you prefer to give it? you can give your source code, os a better option would be to compile your code as a dll and then sell, because the dll after compilation gets converted to machine code.

This is not the purpose of dlls, you should use files or databases for storing your application data.

Thanks for reply dude..
I want to delete through code.

Can you not delete it the same way you'd delete any other file? (DeleteFile)
If you're struggling to find the desktop, you can use SHGetFolderPath with CSIDL_DESKTOPDIRECTORY.

Read the first bit of my post. I repeat: "What is wrong with DeleteFile" ?
CString s = szPathDesktop;
s += _T("\\myshortcut.lnk");
if (!DeleteFile (s))
{
dw = GetLastError ();
}

Hello,
I need to work with DNS primary lookup zone, rigth now I'm doing it by calling shell, anyone knows which dll should I use to add/remove records?
Thanks in advance

You can use the IP Helper API[^] to add/remove DNS lookup zones. I believe there are some samples of its usage here on codeproject.

Hiii dear all,
How to compair two GUIds apart from making them const string and then perform strcmp.
Thank you

I would recommend using memcmp()[^]
memcmp(&guidOld, &guid, sizeof(GUID));

You can also use the == operator on two GUIDs since VC++ has
a built-in overload for comparing GUIDs.

And he could also use IsEqualGUID [^]. So many choices, whats a software engineer to do? Read the documentation maybe?

It looks like that's what the compiled == code calls, which eventually uses memcmp().
Wow...so many choices! Heh

I have create a rich edit control and use the EM_SETZOOM message to scale the text in the control.
code :
1, #define _RICHED_VER 0x0300
2, Create the rich edit control, the handle of the control is m_RichCtrl;
3, SendMessage(m_RichCtrl,EM_SETZOOM,2,10);
but it seems that the EM_SETZOOM message doesn't take effect,why?
