Question

Here is the piece of code, which run through all the process and when It finds the right process, code sends the message. My question is what happened to the ‘proc’, how to dispose that process.

//get all other (possible) running instances
        Process[] processes = Process.GetProcesses();            
        foreach (Process proc in processes)
        {
            if (proc.ProcessName.ToLower() == ProcessName.ToLower())
            {
                SendMessage(proc.MainWindowHandle, (uint)Message, IntPtr.Zero, IntPtr.Zero);
            }               
        }

Thanks in advance,
Harsha

In general terms you don’t need to worry about disposing or deallocating objects, unless the object implements the IDisposable interface. If it does you should either call the Dispose() method on it manually when you’re finished, or wrap with a using statement to have it called automatically:

using (var disposableObject = new DisposableType())
{
    // do work with disposableObject
}
