I'm having a problem resolving some namespace isses.

in my project I have:
main.cpp: #include <iostream.h>
main.cpp: #include "timestamp.h"

timestamp.h: #include "timelist.h"
timestamp.h:...

thanks guys, I forget that one too often

I changed it to #include <list> and I get more errors... :confused:

"c:\dev-cpp\fabsim\timelist.h(18) : error C2143: syntax error : missing ';' before '<'
c:\dev-cpp\fabsim\timelist.h(18) :...

In my project I declare a list:

#include <list.h>
list<unsigned> tsList;

and when I compile I get errors:
"c:\program files\microsoft visual studio\vc98\include\list.h(37) : error C2146:...

THanks guys, I figured it out, there was actually a bug in the retrieval function so that it was overwritting the data :O

Can I use winsock to join a multicast group and send/recieve multicasts transmissions? It seems that the key player in this is talking IGMP to join the multicast group.

another option is to address the array dynamically


//here's a ptr to our array
string * theArray;
int numElements = 4;
theArray = new string[numElements];


of course if you want to resize...

why would this be better than building a linked list with pointers to the next index by each field ie:



class LInkList
{
public:

int add();
int field1next();

I haven't tested this but, assuming contiguous memory:

renaming the variable did work, defining the namespace didn't, odd that I didn't have this problem compiling the other day...

wanna take a shot at this one:
