Yes. I can get the attributes in constructor.

Then declare your class variable in header file as public and initialize it in constructor and ckeck this variable in destructor is it null or not?
I think if itis not null then you can access its members, no problem with it.

I want to set the value of variable in constructor before the calling of all functions in class and delete it after runing of all functions in deconstructor, not before or after the calling of every function.
If there is only one function in my class, the value of variable is still available in deconstructor. If there are more than one functions in my class, the variable is null.
If I declare the variable in .cpp file. I can get its value after calling all of the functions in deconstructor.

hi all,
i'm developing an application using MFC dialog. I have to position the buttons and other controls depening on the Size of the screen.can anybody tell me how to do that, if possibel with sample code.
My dialog properties is set to MAXIMIZED
||SnAkeBed||

|
|
|
Do you want to use of WM_SIZE?
|
|
|
|
|
ya .. could you tell me how to use that properly
||SnAkeBed||
|
|

You should have a message handler for WM_SIZE message in your CDialog class. While resizing, the handler will be called with the dialog's width and height value. Deciside where to place your controls with respect to the size.
To position the controls you can use
SetWindowPos(...)
or
MoveWindow(...)
Do your Duty and Don't expect the Result

See if the Extras section of this article is of any help.

What does it have to do with a thread pool ?
|
|
|
|
|
You mean you want to have 500 threads for your application ? Wow, that's a lot ! You'll probably spend more time switching between the different threads than doing usefull stuff. Why do you need so much threads ?
|

Why do you need one thread per request ? You could simply have one thread to queue the requests and one thread (or more) to process them.

i am having 100 threads in my server IOCP.. and it is listening for incoming connections.ok..
in client side i am using 500 threads, to send connection request to the server..!
why 500 threads i am using is, 500 simultanous user trying to access server at a time....
now only 400 client requests are processed(accepted)...remaining 100 error ocurred...
what to do for this..?
Born to win...!

Try using Overlapped IO. In most cases it has proven to be more scalable than hand built threading schemes. Based on the description you provided it will likely be an improvement.
What bank is this for? I want to make sure an never use it.

How many processors does your server have?
500 threads is a huge waste of resources on a machine with say, 4 processors.
See Tip #2 here: INFO: Design Issues When Using IOCP in a Winsock Server[^]
You should be able to handle thousands of connections with at most, a couple threads
per CPU.
Regardless, IOCPs don't have multiple thread pools. The thread pool size is
determined by how many threads you have waiting on GetQueuedCompletionStatus().
