Why not set a breakpoint in both, run the program, and note which breakpoint is hit first?

A task infront of me is to develop local chat server
which will just accept data from everyone and pass it to person whom it is to be send.
Server compiles fine but as soon as I run it ,it fails. Errors come at Accept statement.
The requirement is due to internet is not allowed.
And way for instant communication is required as comapany
layout is very complecated to reach from one room to other. Official mail is too inconvenient for small messages.

//CSocket cs,cr[500]; defined in h file
// bool connected;

BOOL CChatserverDlg::OnInitDialog()
{
CDialog::OnInitDialog();
---------------
------------------
----------------
count = 0;
connected = false;
connected = cs.Create(4000,SOCK_STREAM);
SilentWork();
return TRUE;
}

void CChatserverDlg::SilentWork()
{
bool check = false;
check = cs.Listen();
for(int i = 0;i < 500;i++) //even I reduce number error comes
{
AfxBeginThread(&thread,0);
count++;
}

}

UINT thread(LPVOID p)
{
CChatserverDlg* dlg = (CChatserverDlg*)AfxGetApp()->GetMainWnd();
SOCKADDR* lpSockAddr;
dlg->cs.Accept(dlg->cr[count],lpSockAddr );
while(dlg->connected)
{
ULONG nBytesToReceive=0;
DWORD dwErr;
if( !dlg->cr[count].IOCtl(FIONREAD, &nBytesToReceive))
{
dwErr = WSAGetLastError();
}
if( nBytesToReceive==0 )
{ }
else
{
char* buff = new char[15];
try
{
dlg->cr[count].Receive(buff,15,0);
}
catch(CException e)
{
}
dlg->m_ldList1.AddString(buff);
char* data = new char[1024];
bool continueloop = true;
do
{
ULONG ToReceive=0;
if( !dlg->cr[count].IOCtl(FIONREAD, &ToReceive))
{
dwErr = WSAGetLastError();
}
if( ToReceive==0 )
{ }
else
{
dlg->cr[count].Receive(data,1023,0);
dlg->cr[count].SendTo(data,1023,4000,buff,0);
if(NULL != strstr("diconnected",data))
continueloop = false;
}
}while(continueloop);

Have you stepped into this code to determine why?

What happens if you run this code

CButton myButton;
myButton.Create("button", BS_AUTO3STATE|WS_CHILD|WS_VISIBLE,
  CRect(0,0,100,23), this, 1);
myButton.SetCheck( BST_CHECKED);

Greek character in ascii?

Is it possible to write greek characters in VC++ Dialog window?

I found that the greek ascii code for alpha is 0xE0. But it didnt work. Here's my code:

Cstring TempStr;
TempStr.Format("%c (alpha)", 0xE0);

The character displayed as an 'a' with an ascent mark.

I don't think that alpha occurs in ASCII, that's what Unicode is for.

I didn't think so either. I was shocked when my coworker showed me a chart containing greek letters. The ascii chart I know of only goes up to 7F. He showed me one that goes to FF

It's not an ASCII[^] chart, it's a chart for some 8-bit character set, e.g. one of the ISO 8859[^] parts.

I'm going to develp a program having the similar function as Input Method, and I also like to use the same interface. Let's say a some kind of Input Method I plan to develop (actually not). Where can I start from? any windows development platform can support. is IME itself a development platform? if yes, what can I do next step. if not, any suggestions? Thank you!
