Just how do you plan to use it? You do realize that to use the class, unless you are talking about a static (class) function, you need an object of the class. So how are you getting this object & how long are you keeping it for? How does it relate to the rest of the program? An object of Classdrv2 of its own for the entire lifetime of a Classdrv1 object? An object of Classdrv2 just for use during the execution of a member function of Classdrv1? An object of Classdrv2 provided by a caller for manipulation by a member function of Classdrv1? There are lots of possibilities. Which is right for your situation depends on what you are trying to achieve. If you explained more, you might get more focused answers.

I don't use the devenv program, but from a batch file I use something like this: vcbuild /r /useenv \Source\Mapp\bld\myapp.sln $ALL Hope that helps. Karl - WK5M PP-ASEL-IA (N43CS) PGP Key: 0xDB02E193 PGP Key Fingerprint: 8F06 5A2E 2735 892B 821C 871A 0411 94EA DB02 E193

Can you remove ExportSlotCoreLib from pSingleton declaration and try?

If not what is the best way to do it? Using FindWindow() could work or it could possibly result in a failure or a deadlock. What FindWindow() does internally is call EnumWindows(), and for each top-level window handle found, it sends a WM_GETTEXT message to the window handle. Now if the thread that owns the handle is blocked (e.g., on a Semaphore, a Mutex, an Event, an I/O operation, or some other manner), the SendMessage() call will block until that thread is freed up. Worst case, this may never happen so FindWindow() will block forever. "One man's wage rise is another man's price increase." - Harold Wilson "Fireproof doesn't mean the fire will never come.

So…lets look at the code you posted: class Client; Client(const Client&); and what (judging by your answer) you should have posted: class Client { Client(const &Client); }; Your original code was syntactically incorrect and at the same time had the syntax (const Client&) that you now report as fixing the problem. If you're going to post problems with a code snippet, at least make it an accurate code snippet... Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

Look at what the function is supposed to return (a std::list) and look at what you are actually returning (an integer). IF you want this to work, you either have to change the return type to long or return a std::list object form your function.

Thanks, its working fine. Similarly is there any way to give the time as input and get the out put calculated for next 72 hours. For Example in-put will in the format "Thu, 13 Nov 2008 12:11:20 GMT" and i need the out-put as "Mon, 10 Nov 2008 11:11:20 GMT", this is calculated for next 72. Is it possible to give in-time and get calculated for next 72 hours? -Nandu

You cannot use strcpy_s in versions of C++ before VS 2005. Download Visual Studio Express for C++ if you want to use it for free. However, you loose MFC and ATL, for example.

lstrcpynA(errmsg, bufsize); If using TCHAR, do: lstrcpyn(errmsg, bufsize / sizeof(TCHAR)); (lstrcpyn is a tiny bit more efficient than strncpy since it doesn't fill the rest of the buffer with zeros after completing the copy. With large buffers, this is generally a waste of cycles.) Anyone who thinks he has a better idea of what's good for people than people do is a swine. - P.J. O'Rourke
