Hello All,

What is HANDLE in C Programming? How can this be implemented in C#.NET?
Thanx in advance.

Of course there is an entry in wkipedia for this if you care to look.

I think an example that we see early on learning in C would be the what the stdio.h datatype "FILE" is for.

CPP / C++ / C Code:

    FILE fp;   /* an identifier of the right type to hold a file 'handle' */
    ...
    fp = fopen( "myfile", "r");     /* We request a 'handle' from the system
                                       through which we can access the file */

We might also request a handle to a "window".
Not sure but a pointer to allocated memory space from malloc() might be another example.

I think you will need to get acquainted with msdn and find another forum for help with C#.NET
There is a .NET forum here at GID that looks like it could use your help! google c# is helpful...
