you can use the mciSendString API for this

using System.Runtime.InteropServices;
 
[DllImport("winmm", EntryPoint="mciSendStringA")]
private static extern int mciSendString(string lpszCommand,  string lpszReturnString, int cchReturnLength, int hwndCallback);


         private void button1_Click(object sender, System.EventArgs e)
         {
              mciSendString("Set cdaudio door open wait", "", 0, 0);
         }

         private void button2_Click(object sender, System.EventArgs e)
         {
           mciSendString("Set cdaudio door closed wait", "", 0, 0);
         }

Your reply was perfect. I just had the idea but was messed up in my mind. The thing I want to ask you here, how can I get that data about the dll I am importing and refering to like the one you used winmm,dll ? Sounds foolish , but I always used my dlls and declared everything as public and of course I know the code I wrote for my self.
