recvmsg = "PING :########";(the #''s are random numbers & letters) what i want to know how to do is take the value of recvmsg, and store the ######## in a variable. The ######## arn''t known at compile time, they are learned while its running. Any ideas? ThX

When I have to do stuff like that, I use my nifty little right() function. It returns the right n characters of a string. So you would use it like:

char* right(char* Txt, int Num)
{
char *Buf;
int l=strlen(Txt);
Buf=new char[Num];

for(int i=(l-Num);i{
Buf[i-(l-Num)]=Txt ;
}

Buf[Num]='\0';

return Buf;
}

char* Msg=right(recvmsg,strlen(recvmsg)-6);
// -6 because your 'PING :' is 6 characters long

Hope this helps!

EDIT: stupid text formatting...

The function for this is sscanf. I believe the below will do.

Example:
sscanf(recvmsg, "PING :%s", stringVar);

Ok...my text above got a bit screwed...
that for loop should be
for(int i=(l-num);i
EDIT:
Moderators/Admin people...why won't my text display properly? Did I do something wrong? Are you not allowed to use the less-than symbol?

The less-than symbol is used for HTML tags, so you can display links for example. I believe you can put less-than symbols correctly inside [ source] [ /source] tags. Let me try:

                
Less-than symbol: <


Yep, it works.
