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...

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 .

my test environment is in LAN

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.

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.

for example
try {
Bitmap bmp(path);
} catch () {
]
CMainFrame *pMF=(CMainFrame *)AfxGetMainWnd();
TCHAR Path[MAX_PATH];
TCHAR FullPath[MAX_PATH];
BROWSEINFO bi;
::memset(&bi,0,sizeof(bi));
bi.hwndOwner=m_hWnd;
bi.pszDisplayName=Path;
bi.lpszTitle=TEXT("Select a directory");
bi.ulFlags=BIF_DONTGOBELOWDOMAIN|BIF_EDITBOX|BIF_NEWDIALOGSTYLE
|BIF_NONEWFOLDERBUTTON|BIF_RETURNONLYFSDIRS|BIF_STATUSTEXT;
LPCITEMIDLIST pidl=SHBrowseForFolder(&bi);

int len=_tcslen(FullPath);
CString s(FullPath);
s+=TEXT("\\*.jpg");
CFileFind ff;

CString FilePath=ff.GetFilePath();

Have you verified value of FilePath is it valid file path??
i guess you also have to do following
CString FilePath=ff.GetFilePath();
FilePath = FilePath + "\\" + ff.GetFileName();
i am not sure about the "\\" it might be already there in GetFilePath.
Thanks,
Sandip.

Yes, the FilePath can't be wrong.
|
|
|
|
|
You are also not checking it for directory??
|
|
|
|
|
Not yet. But I set a breakpoint there to make sure the path is all right.

Hi all,
I want to convert my LPCSTR value to char* how to do so.
Can anybody please help me in this.
Thanks in advance
|
|
|
|
|
LPCSTR is a const char pointer. Why do you want to remove the const ?
When asking a question, please be specific and tell exactly what you are trying to do. So, in which context do you want this conversion ?
