Whenever i debug a dll thru the main application the execution is not coming to the break point inside the dll and whenever i press shift+F5 it is showing "Preloaded symbols may not match <mydllname>.dll."
Please tell me what is happening.
Thanks in advance,
John

In your debug settings, under Additional DLLs, did you happen to add the DLL so that you may set breakpoints in it before running the application? If so, you may have provided the wrong DLL path.
This can happen if you specify a Debug configuration path (e.g. "C:\...\Debug\MyDLL.dll") whereas the application loads the Release configuration of the same DLL (e.g. from "C:\...\Release\MyDLL.dll"). Although the two DLLs have the same name, they are loaded as separate modules into memory. The breakpoints are set in the module that never gets a chance to run.
This can also happen if your DLL is a COM server (e.g. implements an ActiveX control). Whether the Release or Debug version of the DLL gets loaded depends on the last settings made in the registry. You need to lookup the CLSID of the implemented ActiveX control (HKEY_LOCAL_MACHINE\SOFTWARE\CLSID\yourclsid) and see what InProcServer DLL is registered - the release or debug version. Then, in your application's debug settings, you need to synchronize the specified DLL path to this.
Hope this helps.

hey guys,i have been working on a little demo ftp program,where the server has read data into a buffer and is sending it to the client which inturn will write the file to a directory on the local drive,but im wondering what the best way to send the data is? if i was sending a lage file would i be able to send the data in one whole chunk? or is there only so much data a winsock send function can handle at any one time,would the data have to be sent seperatly in chunks and then put back together at the other end? any brief information would be great. thanks chris

Dear Mr;
I need some help to solve this programming question if you please the question said:
If we have a file of record (i.e. student.Dat)
Given the following record structure,
St_ Rec = record
St_ no : longint ; { primary key }
St_ name : string [50]; {secondary key 1}
Ma-jor : string [2]; {secondary key 2}
Year : byte; {secondary key 3}
Address : sting [50];
End
Write a c++ program that
2) Allows the user do the following
a) Add and delete a record dynamically (Using the avail list)
b) Modify the information in any given record
c) Query the data file using single key or combination of two secondary keys (and / or)
d) Display the contents of the file page by page in table format
Note 1:- use menu to allow the user to choose the required operation.
Note 2:- use canonical form for names

hi ,
this is about memory/speed size optim.
take this for example:
const int cAIMessageRouter_Init_ReserveRegisteredObjectCount = 64;
const int cAIMessageRouter_Init_ReserveDelayedMessagesCount = 16;
if i replace the int with a char or short.... what would be better....
Size does matter becouse every BIT send to the server ..........
How smaller the player data, how faster the server can respond.
But i dont know this: is const char value=12;
FASTER then
const short value=12;
const int value=12;
or slower?

Try it out yourself by using sizeof and passing each of those items. example:
cout << "Size of an integer: " << sizeof(int) << endl;
|
|
|
|
|
if i do sizeof(int) i get 32 or 16.
With a char i get 8 
But if i use a char to hold a integer value of 5, wouldn`t that be slower?
becouse chars are mainly used for strings.

Characters are represented by a numeric value. It is that value that is stored in your variable not the letter itself, for chars these are the ASCII values. So its just as fast to use a number as it is to use a letter.

Thanx.
The game (soldner secret wars) i am working on (mainly patches) has many data like:
const int max_sounds=5;
by using this:
const char max_sounds=5;
i can optimize SIZE, becouse 20 classes uses 1 class for work that has this defined.
or am i wrong?

Not exactly true. Char's are used for lots of things, including pure data manipulation. It's simply 2 bytes which can be interpreted as an ANSII character. That said, if you're only going to be holding very small numbers like 5 and you're EXTREMELY worried about space/efficiency, you should use BYTE for values which you know will be less than 16. I'm not sure how much time this will all save you to be honest, these types of issues are normally only a passing thought in designing your application because there are so many more design issues that would likely speed up your program much more.

thanx,
at this moment we have still (mod-team) status... and i am the only c/c++ coder.
This forum is a great help.
(talks are going on about soldner 2 www.secretwars.net= www.soldner.jowood.com)
You might wonder why this game source is so complicated  lol.
(i hate wings !!!, crappy coders!!!!)
i can use a few helping hands making soldner a better game, if you are interested.....
The source is like this:
dynamics,core etc is defined in classes, DEEP polymorpish and derived stuff.
(just defined..... no value`s in c++)
The xml and python is used to define the game property`s.
Thats called the gdb::xxxxx (game database).
The gdb is implemented in c/c++ but called from python and xml.
becouse of this complexity, i am seeking for talented coders.
At our team talks are going on about a contract with jowood.
We where/are a mod team, but i think thats changing rapidly.
Jowood needs project zero, without project zero NO soldner.
Cu at the soldner battlefield.

what's that crap ?
char is an integer in C/C++, and its name is quite bad as beginners make too much confusion... a char is only a 8 bits integer. in C/C++, there's no high level type for strings. strings are simply char arrays, ended with a char whose value is 0.
never using a char will slow down your application compared to an int for such a use...
however, you'll have to consider the values stored within... char is a signed type, so stored values between -128 and 127. if you want values from 0 to 255, use unsigned char. and if you want more, use short, int (size is dependant of the plateform ; can be 8, 12, 32 or 64 bits !!! be careful !), long...

It is not so that using integers (32 bits) will slow your applications compared to using chars (signed or not of importance since 8 bit is 8 bit).
In game development speed is everything and a 32 bit CPU processes 32 bit values quicker then 8 bit values. So using an int is faster then a char.
