Creating Windows Shell (CLI based)?

[Awais Ali]

hy guyz,
I want to create a windows 'shell'(CLI based) in C++ (like Windows cmd) which has ability to Create folder or file, copy and paste and delete folders or files...
So plz help me and tell me the which libraries will use because i have no idea about this.
If any person found the beginner-level tutorial then tell me....

Check out something like this:
It is a simple framework where you can add your commands.
Keep in mind you will need to fix it to handle commands with parameters.

// DW_393014.cpp : main project file.

#include "stdafx.h"

using namespace System;
using namespace System::Collections::Generic;
using namespace System::IO;
using namespace System::Linq;

public ref class CCommands
{
public:
   static void ShowDir(void)
   {
      Enumerable::ToList<String^>(
         Directory::GetFiles(Directory::GetCurrentDirectory()))
         ->ForEach(gcnew Action<String^>(Console::WriteLine));
   }

   static String^ NowTime()
   {
      DateTime^ dt = DateTime::Now;
      return String::Format("{0:G}:{1:G}:{2:G}",
         dt->Hour.ToString()->PadLeft(2, '0'),
         dt->Minute.ToString()->PadLeft(2, '0'),
         dt->Second.ToString()->PadLeft(2, '0')
         );
   }

   static void DoHelp()
   {
      Console::WriteLine("Commands are: " +
         String::Join(", ",
            Enumerable::ToList<String^>(
               Enumerable::Select(GetCommands(),
                  gcnew Func<KeyValuePair<String^, Action^>,String^>(GetKey)))
                     ->ToArray()) + ", quit, exit");
   }

   static List<KeyValuePair<String^, Action^>>^ GetCommands()
   {
      List<KeyValuePair<String^, Action^>>^ lst_kvp_s2aCommands = gcnew List<KeyValuePair<String^, Action^>>();
      lst_kvp_s2aCommands->Add(KeyValuePair<String^, Action^>("spy", gcnew Action(CCommands::ShowDir)));
      lst_kvp_s2aCommands->Add(KeyValuePair<String^, Action^>("wipe", gcnew Action(Console::Clear)));
      lst_kvp_s2aCommands->Add(KeyValuePair<String^, Action^>("help", gcnew Action(CCommands::DoHelp)));
      return lst_kvp_s2aCommands;
   }

private:
   static String^ GetKey(KeyValuePair<String^, Action^> kvp_s2a)
   {
      return kvp_s2a.Key;
   }
};

int main(array<System::String ^> ^args)
{
   Console::WriteLine(L"Welcome to CLI Shell (v1.0)\n");
   String^ strCommand = "";

   List<KeyValuePair<String^, Action^>>^ lst_kvp_s2aCommands = CCommands::GetCommands();

   while(!strCommand->Equals("exit") && !strCommand->Equals("quit"))
   {
      Console::Write("{0}>: ", CCommands::NowTime());
      strCommand = Console::ReadLine()->ToLower();

      for each(KeyValuePair<String^, Action^> kvp_s2a in lst_kvp_s2aCommands)
      {
         if(!kvp_s2a.Key->Equals(strCommand))
         {
            continue;
         }

         kvp_s2a.Value();
      }
   }

   return 0;
}

i compiled your code in Dev-cpp, it displays no. of errors...
And tell me that where your code will successfully compiled?

[Awais Ali]

You have not attach #include "stdafx.h" file, so i think due to this it not compiled successfully...

[thines01]

Line three (3) is the include of stdafx.h
I created this with VS 2010 and compiled it with Warning Level 4.

when i compile ur code then these following errors display:

This code also requires the Dot Net 3.5 framework (C++/CLI as you requested).

The stdafx reference was created by Visual Studio.
The .h file contains only one line

#pragma once

The multitude of errors you're getting suggest that you do not have your environment set up properly.

Start with the first error:
'System' : a namespace with this name does not exist
The System namespace is an integral part of the Dot Net framework.
If it can't be found, either you are not building this as a dot net app or your environment is messed up.

[thines01]

Did you fix it?
If not, you should start a new Console App project WITH Pre-compiled header.
Once created, paste this code into the main module.

Correction on my statement:
It requires at least Dot Net 3.5 (4+ if you're using VS 2010)

[thines01]

Did you fix it?

[Awais Ali]

i am not aware about visual studio compiler..
Please can anyone tell me the code that can run on Dev-cpp...

[thines01]

I'm not sure if Dev C++ can compile CLI code.

Here is also the Wikipedia page.

You can get Visual Studio C++ Express for free.

I guess you can also just download the dot net SDK and compile it from the command-line.

[thines01]

Have you read this article titled,"Why we've deprecated Dev-C++."?

It mentions Visual Studio as an alternative.
It will probably be the only compiler that can handle the CLI code you requested.
