how to register class name for window

Start commenting out code (preferably in reverse order of how it was added) until the compiler is happy. Then you will know the offending statement(s).

Hi Genius,

i have created one dialog based MFC application in that i have to register the window class name and then i have to use FindWindow()
API to find that window by using that registered class name.i have coded like this in InitInstance() section.

WndClass wc;

wc.lpszclassname="sample class name";

AfxRegisterWindow(&wc);

After that in tht onInitDialog section iam trying to use FindWidow API like.

::FindWindow(_T("sample class name"),NULL);

its not woking i cant find that window,but by using title i can find that window.any can help me to use findwindow API with my own class name.

Thanks in advance,

Nothing is Impossible...

In your created program, trace the software into the AfxRegisterClass, making sure that the values for wc are set sensibly. Then trace into the CreateWindow class bit to make sure that it actually uses your class, not some default one that happens to work.

Lastly, use spy++ to check out your window, and that it does have the class correctly. (ok, do this first too!)

You mean AfxRegisterClass ?

Just registering a Window Class doesnot create a window of the class or doesnot associate already created window with the class name. I guess you misuderstood that when calling AfxRegisterClass your dialog app window is associated with the window class, you have to create the window with the class name.

Hello friends,
I am using VC6.0 IDE with Platform SDK Sp3.
I am using Winsock api for client server programming.
I want to develop a server which is responds (i.e. send/receive packets, getting acknowledgment when client closed or net down or network) for atleast 8000 clients.
The following are my problem:
1) For 8000 clients maintaining an array of socket handle is difficult and takes lot of unwanted memory or may show memory excpetion.
2) On Server side, it may possible that server PC having 2 to 3 network adapters with different IP address range (e.g. one adapter for internal LAN and another is connected to ISP through router etc…)
3) Some PC are connected by Host, NAT
4) Some (HR or Company managers) PCs are connected through wi-fi wireless network or used VPN.

So I want to consider all these possibility.
Please give me a suggestion that, what strategy at the time of development is better for me so my server can be error prone and it should work in all condition.

hai,
u told that u are using win sock api... if ur server want to serve more then 8000 clients means..u have to step into IOCP method.

Using Iocp 55000 clients we can connect simultanously...

In our code project site itself so many articles are there to refer IOCP..

This is the basic link to learn IOCp...

Hope ur first problem will be solved...!

Thanks.

If you're using MFC, then CTime and CTimeSpan will do the magic. See [^].
