you got 2 choices. or you comment the "using namespace std" line and use std:: in front of all the types that need it OR you uncomment the line and remove std:: in front of all the types that need it.
A namespace is a realm in which the code is defined.
you can define some code in a namespace like this
namespace blah {
typedef bloh int;
}
blah::bloh myvar = 4;
if I insert this
use namespace blah;
then I can only use
bloh myvar = 4;

ok nice one, made a fair bit of progress thanks to you but this is a bit shocking. The below code gives 0 errors, but 121 warnings LOL. and also, it prints Mark twice (in the exe window) where it should print Mark, and then Harry, as I changed the data from mark to harry
// hhh.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <map>
#include <string>
using namespace std;
typedef std::map<std::string, std::string> MyMap;
MyMap TestMap;
int main() {
std::string chan( "#Channel" ); //keytype
std::string mark( "Mark" ); //datatype
TestMap.insert( MyMap::value_type( chan, mark ) );
MyMap::iterator it = TestMap.find( chan );
//this should print Mark
if ( it != TestMap.end( ) ) {
printf( (*it).second.c_str( ) );
printf("\n");
}
//change #channel value from Mark to Harry
TestMap.clear;
std::string harry( "Harry" );
TestMap.insert( MyMap::value_type( chan, harry ) );
//this should now print Harry
if ( it != TestMap.end( ) ) {
printf( (*it).second.c_str( ) );
printf("\n");
}
return 0;
}

I think you misunderstood me on the "using namespace std;" if you use it, you have to omit the std:: in front of the types you use that come from the library. If you don't, you have to insert them in front or the system will say he can't find the type you are using. And .clear( ) is a function not an argument. I compiled this code on VC++2003 and it works like a charm and prints the names correctly.
#include <stdio.h>
#include <map>
#include <string>
//using namespace std;
typedef std::map<std::string, std::string> MyMap;
MyMap TestMap;
int main() {
std::string chan( "#Channel" ); //keytype
std::string mark( "Mark" ); //datatype
TestMap.insert( MyMap::value_type( chan, mark ) );
MyMap::iterator it = TestMap.find( chan );
//this should print Mark
if ( it != TestMap.end( ) ) {
printf( (*it).second.c_str( ) );
printf("\n");
}
//change #channel value from Mark to Harry
TestMap.clear( );
std::string harry( "Harry" );
TestMap.insert( MyMap::value_type( chan, harry ) );
//this should now print Harry
if ( it != TestMap.end( ) ) {
printf( (*it).second.c_str( ) );
printf("\n");
}
return 0;
}

:S this is very odd then, im doing something badly wrong then because I get
Linking...
hhh.exe - 0 error(s), 122 warning(s) which prints Mark twice in the c:\hhh\hhh.exe debug exe when i click on
execute hhh.exe from the build menu :S
(im using the exact code you pasted)
the version im using is visual c++ 6.0, and its all in a win32 console application, hope someone can tell me if im doing anything wrong, i really would like to get this working, thanks guys

try putting this at the top
#pragma warning( disable : 4530 )
I know the STL is a little hippy about warnings sometimes.
But I can't see what you are doing wrong, make sure you use the code I provided. Could also be your compilator (or mine) which doesn't compile stuff the same way.

Remake a new project and select "Empty project" instead of the choice you made that includes precompiled headers (the stdafx.h .cpp files which you really don't need and may be causing more harm than good in your case).
I never use them either.

ok thanks, ive dont exactly that, and for some reason it gives me 123 warnings still (and stil prints the names wrong), you can see it in the build log and heres the small project www.geocities.com/pouncer_123456/testNew.zipthe code is exactly the same as yours, its kind off spoilt all the plans i had for this dll, i cant do anything now :S i noticed many of those errors had this in it c:\program files\microsoft visual studio\vc98\include\map heres the map file which i found in that directory, not sure if there might be a problem with that http://www.geocities.com/pouncer_123456/map.txt

remove that ; after the first #include
and I said clearly that TestMap.clear is a function not an attribute and should be
TestMap.clear( ); <----
The rest compiles fine here, noe warnings or errors and returns
Mark
Harry
I think you aren't too familiar with C programming to make these kinds of omissions, maybe you should invest time to learn C/C++ before trying to tackle this type of problem which is obviously a little intermediate to advanced stuff. This demo is simple, but it can get ugly quickly if you want to add more stuff to it.

ok, corrected both of those things you said, still the 123 warnings (no errors though)
and prints names wrong
i give up, i dont know why an earth this is happening, must be the map class on my pc or something?
erm hangon, are you only compiling it from the 'build' menu?
i got 0 error, 0 warning when i did that
but when i click on 'rebuild all' thats where all the warnings come up

I get 0 errors when I rebuild all, build, or any other compile options.
You should try to install SP4 of Visual Studio 6 and also the latest SDK with the latest libs.

sorry for bringing this thread back david but just a quick Q,
#include <string>
using namespace std;
typedef map<string, string> MyMap;
MyMap TestMap;
i removed the std::'s, as im 'using namespace std', but it just keeps saying error C2143: syntax error : missing ';' before '<' like 4 times :S

If you want to use a map, you need to include the header for it:
#include <map>
Gone.

ok thanks sorted that part, got it about 90% working now. but im trying to return an entry in a seperate function (and storing an entry in another function)
string channel = data;
iT = KeyStorer.find(channel);
string key = (*iT).second.c_str( );
_fstrcpy(data, key.c_str());
return 3;
as you see above the data is the channel name i ffed into the dll parameter, keyStorer is the map instance name, its definately storing the key, but its just crashing my mirc when i use the above code to grab the key, any ideas guys? ive got all this stored at the top typedef map<string, string> MapFunction; MapFunction KeyStorer; MapFunction::iterator iT;

string channel = data;
MapFunction::iterator it = KeyStorer.find( channel );
if ( it != KeyStorer.end( ) )
lstrcpy( data, (*it).second.c_str( ) );
else
lstrcpy( data, "Key Not Found" );
return 3;

thanks for the reply, this is very weird. heres the code
//stuff at the top for maps etc
typedef map<string, string> MapFunction;
MapFunction KeyStorer;
MapFunction::iterator iT;
extern "C" int WINAPI StoreKey(HWND, HWND, char *data, char *parms, BOOL, BOOL) {
string channel = GetTok(data, 1, 32);
string key = GetTok(data, 2, 32);
KeyStorer.insert(MapFunction::value_type(channel, key));
return 1;
}
extern "C" int WINAPI GetKey(HWND, HWND, char *data, char *parms, BOOL, BOOL) {
string channel = data;
MapFunction::iterator it = KeyStorer.find( channel );
if ( it != KeyStorer.end( ) )
lstrcpy( data, (*it).second.c_str( ) );
else
lstrcpy( data, "Key Not Found" );
return 3;
}
//.dll Test.dll StoreKey #hello testkey then //echo -a $dll(Test.dll, GetKey, #hello) - should echo testkey but it just echos 'no key found' :S

then I'm sorry to say that your code to insert is flawed with that Gettok stuff
Look at your insert params to see what is going on
