I regret that i posted the same question in many forums.
my software is related client- server relationship in which server appication runs in the server and client appication in the client computers.whenever any user login in a particular computer in the lan that pc with user name will be displayed in the main listbox of the application that is running in the server in order to administrate the whole LAN. whenever any user login to the computer that client application extracts the server ip address from registry as i am using the 2 or 3 registry keys. the problem is not with administrator account as it has permission to access the registry values but the problem is with local users who have no such permissions.
so i want to set permissions for those 2 or 3 registry key values as "full control" for all users so that any user login , he can be displayed in the main window of the server appication running in the server.
so please help

This is usely no good design. But I reckon it depends on what you are trying to achieve. Any more detail ?

Hi, I'm a newbee in programming world and I learn to program in C++ by analyzing source codes. I don't know whether this is good idea but... Anyway the reason why I posted this message here because I have a problem. Whenever I download someones source code ( mainly simple games like tetris) there is included header file called graphics.h. When I compile this source code it reports me that it can't find such header file. What is the problem? I mean I know that i don't have such header file but why? I'm using Visual Studio 6 and VS 2005.

Do you have this file on your computer?

You cannot find graphic.h when you try to compile with visual studio because it is a borland extension. Microsoft uses a different one, so is gnu etc etc.
Try compiling with Borland Builder it should work...
Downloading someone's source code and trying to compile it with vis studio is not enough. You have to take into account which platform was used to write the program. For example you could try download a game which was written for Linux and try to compile it in visual studio. It will most certainly fail because it will use libraries and extensions that were only developed for the linux system.

I think graphics.h is a part of Borland Turbo C++. It does not come with MS Visual studio.
You could install Turbo C++ 3.0 etc to compile the code.
Also you could port it to gcc to run on *nix based systems:

this is this.

First I cant see any ICreateDevEnum on your code and second dont need to post all code and when post a code use of pre tag and can you show your declare of this interface on your cpp file,please.

You must include dshow.h on your code and import lib files to your project.
