HI all,
Is it possible to link STL dynamically to my application? For me it is a bit confusing as template libraries are shipped as source. Hence making those in a DLL does not make sense. Please correct me if I am wrong.
The real problem here is I have a static library produced my latest compiler which uses STL. Now If my client want to use it this library with compiler of lower version, it gives STL class undefined error.
Please help.

Right.

 I don't get you here: using a static library (so, basically a collection of functions and/or classes in executable format) should have nothing to do with such an error...

so if my static library is compiled with newer version of compiler and my client uses it in its code which is compiled with older version of compiler. Things should work fine?
This problem statment utimately boils down to
1) I have one static libray say "A" build with Compiler 2.0, uses STL
2) I have another static library "B" compiled with Compiler 1.0 uses STL
If I try to make my client application with Compiler 1.0. using both the libraries(A and B), will it work?
Does linker allows me to link two libraries carrying different STL instances? Can there be ambiguities or optimization issues?

But...
... the template sources (the only used) must be compiled,
there is no any template LIB/DLL in the nature...
virtual void BeHappy() = 0;

No, because you should not use STL across library boundaries...without really knowing what you do. First of all is STL not a binary compatible interface, you must compile with exactly the same STL version in all modules/libraries/DLLs. There is probably no linker warning/error if you try otherwise. Secondly allocating memory in one module's heap and deallocating in another will fail, if you do not provide special allocators. In short, there is no easy way to use STL in exported interfaces.

Hope it helps!

You are a software developer, aren't you? So, please, read the documentation and develop the software (we would help on that).

Hi..
'm working on my final year(engg) project..
I need to hide my process from the task manager..
developing a remote monitoring utility for a start-up company..
it would be great to achieve this hiding..
coding in win32 using C..
any suggestions as to where to look for would greatly help..
thank yu

Unless you are writing a virus, this is not a good idea. What if your process has a memory leak ? Or slows down the computer ? You have to let the user decides what he wants to do with his computer. And as far as I know, it is even impossible to hide a process this way.
(And if you are writing a virus, then asking such a question here is stupid).

Yes, i completely agree with your questioning.
We, two of my team mates and i, are developing a set of plugins- keylogger & screengrabber for a cyber security based company. We are workin as interns. The company 'll be using the project as a utility toolkit for testing purposes, i guess!
I wanted to hide the process so that it would be a more complete product. A more (ethically)professional one.

Write a Linux application and let it run on another PC. This way your Task Manager won't see your process running for sure...

ok.. thank yu..
but the problem is that the application being developed is windows specific..

I can tell you the tricks only, as now I am not using C++ anymore. what ever app is installed in a system, must register themselves(if using a standard deployable package utility) into the system registry. Dont delete their entry point from registry, rather you can alter their entry point from process to services.
Just imagine, have you ever seen any services running inside the task maneger? I guess, no. Every process's entry points contain two main parameter, as name & value. If you change the value from 0 to 1, see what happen...

ok..
i'll try to do that..
thank yu

Never use the idea for a virus
You achieve with API hooking(API Hooking (LoadLibrary)[^]), if you get which API is used by TaskManager to show the process.

thank yu..
no, i surely won't use it for unethical purposes..

The problem is not if it is "etical".
It can be even "illegal".
Your company may be prosecuted by law, if you "spy" your user without letting them to know about that.

This question gets asked often enough to get a little tiresome. Who are you working for so I can make a note never to buy any of their software?

Can you please elaborate, like which IDE you are using. because if you are using MS-VS 2006 or higher , then I guess there is one tool.
