File handling problems again.

This is supposed to look for an object (Object) in a text file.
First of all (using geline) I look for the room. Then I take in the object name (which stands under the room name in the textfile). If Object = objecttxt, then I take in the object info and print it to the screen. I can compile it without an error, but it does''t work when I run it (or rather, it does nothing). I''ve checked all the strings and they contain the correct information when the code that I''ve included here is initiated.
What am I doing wrong?
(ifstream fhi)
while (GetInfoCheck == true){
getline(fhi, temp, ''\n'');
if (temp == currentroom){
fhi >> objecttxt;
if (objecttxt == Object){
GetInfoCheck = false;
getline(fin, temp, ''*'');
system("cls");
cout << room.strRoomDescription;
cout << "\n\n\n\n" << temp;
}
Are you using char* or std::string for your strings? If you use char arrays, you can''t compare them with ==. Use strcmp instead.

I am using strcmp.... the compiling runs smooth without any error.. It''s kinda disturbing

.... And you know that strcmp returns 0 (i.e. false) when the strings are identical? *just checking*

Is that the *actual* code that you have posted? Can you produce a small compilable example of the code that is causing a problem? If so, then post it here and we''ll have a better chance of spotting your problem. There''s too many unknowns in what you''ve posted so far.

catfoodgood: Yes it is opening correctly, and how do I error check it accept checking the messages?
Ksero: Actually, I don''t know what I''m talking about, just guessing.
SabreMan: Ok, but how do I put the code in thoose code windows I''ve seen people doing here?
*Feeling like a total idiot*
But, if you don''t ask, you don''t learn!
Rimrok, I wasn''t trying to be disparaging. When helping someone on a board like this, it''s difficult/impossible to know how much the other person knows. I was just trying to be helpful, though in hindsight, maybe it was a bit too simple...
And the source boxes... check out the forum faq... you write

just flip the brackets around, like []

Ksero: Don''t missunderstand me! I''m really greatful for all help I can get! I made fun of myself, because I really didn''t know what I was talking about when I said that I''m using strcmp, I''m that much of a newbie 
Anyway, here''s the code:
First of all you need to create the test.txt file.
It should look like this:
RoomName
ObjectName
ObjectDiscription*

Recently:
Ok, now this is disturbing... The code that I've posted here runs flawless. But it won't work when I use it as a function in a larger project. I give the function the name of the room and the name of the object, but it can't find it... The wierd thing is, when i print the name of the room/object inside the function, they look like they are supposed to... hmm...
I've solved it now... Havn't got the time to explain...
