How to add a ComboBox to Browseinfo?

5-Dec-07 16:05

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 Poke tongue | ;-P

)
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

about send function!!

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".

It blocks until data is all sent or error occurs.

The underlying network stack and driver were able to output the data before the return back into user-land, therefore your call completed with all bytes sent.

I've never found any relationship between the default buffer sizes and the amount of data I could send into or receive from the network stack. Just check the return values to see how many of the requested bytes were handled and deal with that situation.

Unless your computer is very very very slow I doubt send would ever actually block for a perceptible amount of time. Shouldn't be that hard to push some data from your buffer to the wires, the function doesn't need to wait for anything but your pc and 100KB on a 100Mbit card ... that's easy.
