Winsock recv() problem !

Code:

---

char buff[5];
CString htmlSource;
int rb=recv(conn,buff,sizeof(buff),MSG_PEEK);
while(rb>0)
{
rb=recv(conn,buff,sizeof(buff),MSG_PEEK);
htmlSource+=(CString)buff;
}
return htmlSource;

A very usuall recv() !
I use it to get a http request's response from a server
the problem is that i always recieve the response followed by request i sent !!!
which looks like that...

Code:

---

Host: www.site.com
Connection: Close

ny one got a clue whats wrong ?!

Why are you just peeking at the data?

Code:

---

rb=recv(conn,buff,sizeof(buff),MSG_PEEK);

You append the data whitout checking if any (or how much) data was received. If you want to treat data received using recv as a c-string (zero ended), you need to add the zero yourself. Something like:

Code:

---

while(rb>0)
{
    rb=recv(conn, buff, sizeof(buff) - 1, 0); // make room for ending zero
    buff[rb] = '\0'; // add ending zero
    htmlSource += (CString)buff;
}

---

And maybe you're better off with a do-while statement:

Code:

---

char buff[1024];
CString htmlSource;
do
{
    rb=recv(conn, buff, sizeof(buff) - 1, 0);
    buff[rb] = '\0'; // add ending zero
    htmlSource += (CString)buff;
} while (rb > 0);

return htmlSource;

i peeked data coz i always got the recv function to return the same # of bytes recieved with no new data !...and so i got into an endless loop

ny ur code snippet helped alot...thnx mate
