If you can't do these questions, then either your teacher is useless, you're really dumb, or you spent the classes trying to look up the skirt of the girl sitting next to you. To establish which of these is the problem, ask some of your fellow students, and if all are lost, talk to the school about it. Otherwise, try paying attention in class.
Also try paying attention online - this is the Managed C++ board, not the C++ board.
If you're still stuck, try having a go, and asking more specific questions than 'please do my homework because I can't be bothered'.

hi,
if u know c++ and C# ( i mean CLR ,CTS ).It's Very easy to learn MC++.so u don't have to spend much time on it.u just go on coding in c++ and use classes which u used in c#.
There's lots articles submitted here.so go through it.
to start with select vc.net and then project type managed c++ application.so u are ready to code in c++.
i prefer wrox series for MC++.

Hello,
I'm having trouble trying to use an access declaration. i.e I'm trying to manually change the access level of an inherited member (previously public) to protected. How do I do this in MC++?

hi man,
enjoy coding .see below solution for u r problem.

Hi,
I believe problem with your project file. do one thing
start vc.net then select managed c++ Application.
it will create main method;
cut and paste the code inside sample codes main.

Don't do peoples homework for them, it doesn't help them in the long run. Also, u and r are letters, they are not words.

the following text is:
Note that code is instantiated only for member functions that are called. For class templates, member functions are instantiated only when they are used. This, of course, saves time and space. It has the additional benefit that you can instantiate a class even for those types that cannot perform all the operations of all the member functions, as long as these member functions are not called. As an example, consider a class in which some member functions use the operator < to sort elements. If you refrain from calling these member functions, you can instantiate the class template for types for which operator < is not defined.
what it means?please tell me,thx.

Hi there,
I've created a cli app that allows a user to control windows services. Just a quick question - while trying to "break" the app i noticed that if i performed a pause command on a service that couldnt be paused - the app would just hang. I guess my question is, Is there a way to query the service to find out what control commands it can accept? Any sample code on this would be greatly apprecaited.
Thanks

Is the file in the same folder as your exe ? Also, I can't see your #includes, but the lack of any reference to namespaces makes me thing you've included iostream.h. Don't, this is not valid C++. Use iostream instead ( no .h ). This means you'll need to scope namespace std.

Hi,
My purpose is:
- Write a service
- This service must create thread on every process (on every WindowStation)
Problem is:
CreateRemoteThread in MSDN wrote:
Terminal Services isolates each terminal session by design. Therefore,
CreateRemoteThread fails if the target process is in a different session
than the calling process.
If have many users is loging then have many session. I want to
CreateRemoteThread of every session.
My solution is:
- The first, find window station of the process which I must create thread
on it (use WTSEnumerateProcesses)
- The second, use SetProcessWindowStation to assign a window station to the
calling process (is my service). Result my service will operation on the
window station which I must create thread on a process on it.
- Then, use CreateRemoteThread to create thread. Now, CreateRemoteThread is
successful.
Is this solution true ?
Thank in advance.
PTM.

I am writing a managed wrapper for an unmanaged class. The unmanaged class is stored in a dll. At the top the of the .cpp file for the managed wrapper i have #using<unmanagedclass.dll> I've also added a reference to this dll using the Add References... option. However, when I compile, the compiler does not recognze my unmanaged class.
Thanks

Hey all,
We have a C++ GUI application built with Trolltech's QT and building with Visual Studio as a Win32 application. If I were to want our application to make the switch to managed code would I be able to do this with the third party (QT) libraries? That is it possible to take existing .libs and 'manage' them in my code? Are there any other caveats?
Thanks,
Daniel
