How do I convert my C++ BOOL to a .NET bool for my C# call?

BOOL cpp = TRUE;

bool cs = (bool)(cpp != 0); // the cast may or may not be needed, you can check that out. 

#include "stdafx.h"
#include <iostream>
using namespace System;
using namespace System::Windows::Forms;
using namespace UserActivityMonitor;
using namespace std;

ref class MyEventArgs : MouseEventArgs
{
   public:
     property String^ Info;

	 MyEventArgs(String^ info, MouseButtons button, int clicks, int x, int y, int delta) : MouseEventArgs(button, clicks, x, y, delta)

        Info = info;
     }

delegate void MyEventHandler(Object^ sender, MouseEventArgs^ args);

int _tmain(int argc, _TCHAR* argv[])

	HookManager::MouseMove += gcnew MouseEventHandler(events, &Events::HookManager_MouseMove);

	while (true)

I guess it will require even more code on the generic user-control to wrap around the custom WinForm so it reacts properly to its events.

Conversion between array<String^>^ and const char *const* and back

String^ str = "Hello world!";
IntPtr p = Marshal::StringToHGlobalAnsi(str);
char *nativeString = static_cast<char*>(p.ToPointer());
Marshal::FreeHGlobal(p);

const char* native = "hello world";
String^ managed = gcnew String(f);

For your example, the marshal_context methods are probably most appropriate, then you can leave RAII to clear up the HGlobal stuff internally.

It's simple enough to write.

why does C++ need another type of string for each new string? after all, a string is a string.

It seems C++ offers more string types than I have strings in a typical app. Just wondering why that is.
