c++ map find problem

[codder]

Ok, i have a map hash (string, string)

for(map<string, string>::iterator it = hash.begin(); it != hash.end(); it++)
log_file("first: %s\n", (*it).first.c_str()); // "first_elem" iterated

when i do
map<string,string>::iterator it = hash.find("first_elem");
if (it != hash.end())
log_file("found!\n");
else
log_file("not found!\n");

into log out "not found!"
why???

Well from what you have posted here hash is empty. So you can't find anything that is not in the hash right?

Can you share the code where in you insert "first_elem" in this map. I mean share the whole code to avoid confusion.

if (key != std::string::npos)
{
std::string keyname = sec;
keyname+=":";
keyname += str.substr(0, key);
std::string val = str.substr(key+1, str.size()-key);

mHash.insert(std::make_pair<std::string, std::string>(keyname, val));

FILE *f = fopen("elems.txt","a");
fprintf(f,"%s-%s\n",keyname.c_str(),val.c_str());
}

^ i logged every keyname and val
and i get

cfg:string - lol
cfg:bool - 1
cfg:int - 357
cfg:float - 35.057
cfg:double - 3.14159
server:name - xd

now the problem is here:

std::map<std::string, std::string>::iterator it = mHash.find("cfg:string");
if (it != mHash.end())
{
fprintf(f,"found!\n");
fclose(f);
}

found! isn't logged :(

Its not fully clear for me but I've got the impression that keyname contains a white space at the end (according your log output). It depends on what "key" points to.
