Hello everyone,
Multiplies is a struct, why MSDN said it is a class?

thanks in advance,

Because in C++ a struct and a class are quite similar. The difference is that structs give, by default, public public access to their members, while classes do the opposite (private access, by default, to their members).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

learn your school lessons. in C++, a struct is a class (the only difference is that is defaults is members as public instead of private).

C++ recommands that use class only for its spirit.
struct in C++ is for compatibility with C.
However you can think class as a mentally concept, as a more common concpet, so either can be called a class as you like.

I want to custom a Browseinfo window.
For original Browseinfo only gets the address information, I also want to know which form user choose(xsl,xml,txt,ect) now.
So, I want to add a ComboBox on the Browseinfo window.
I tried, but always encountered error when I calculate the ComboBox's location.
Does anyone have a relative Demo ? (a simple one is better  )
And welcome any idea.
Thanks a lot!

When i call the CDialog::OnOK(); function I get error :
C:\Documents and Settings\Administrator\Desktop\new_pdf_latest\pdf_latest\itagane_latest\itagane_latest\itagane\CTools\daishi.cpp(116) : error C2039: 'OnOK' : is not a member of 'CDialog'
How can I solve this error?

One possibility is deriving your dialog from CDialog
The other one is establishing it by yourself
//in header
//{{AFX_MSG(CDaishi)
virtual void OnOK();
//in cpp
void CDaishi::OnOK()
{
//do whatever you need
}
Forget about it. I didn't pay attention, you are not in MFC.

And how can he derive his CDialog from MFC's CDialog?
I see a little naming conflict...

/in header
//{{AFX_MSG(CDaishi)
void OnOK();
//in cpp
void CDaishi::OnOK()
{
//do whatever you need
CDialog::OnOk();
}
Remove the virtual keyword in the header.it will Work

SOCKET s = socket(AF_INET,SOCK_STREAM,0);
after I successfully connect to server,I use send function to send data.
I use default buffer and i get default value is 8192. and i don't set s to nonblocking. as following is my code fragment:
char buf[100*1024]={0};
memset(buf,0x08,sizeof(buf));
int nRet = send(s,buf,sizeof(buf),0);
but this function successfully complete. according to my understand,this function should in blocking .

Whts the value of iRet??
if it is SOCKET_ERROR find the error by using WSAGetLastError()
or if it equals the byte actual bytes sent then nothing wrong in it.
and as far as ur question goes i guess it is supposed to be blocking call
Thanks,
Sandip.

nRet 's value equals 102400. this socket is in blocking mode. Because the default buffer size is 8192 bytes, and i send 102400 bytes. Obviously, 102400 is bigger than 8192, so this i/o operation should be blocked, but the actual result is that this i/o operation completes immediately.
P.S. The environment of the test is "LAN".
Thanks

It blocks until data is all sent or error occurs.
