Step by step guide 1. Open C#.net web applications. And added the blow namespace. using Microsoft.VisualBasic.Devices; using Microsoft.VisualBasic; using System.Runtime.InteropServices; 2. Add the below API. [DllImport("winmm.dll", EntryPoint = "mciSendStringA", CharSet = CharSet.Ansi, SetLastError = true, ExactSpelling = true)] private static extern int mciSendString(string lpstrCommand, string lpstrReturnString, int uReturnLength, int hwndCallback); 3. Create three Buttons and given the below name and text for the buttons. 1. Record 2. SaveStop 3. Read 1. Under Record Button Click paste the below Code: // record from microphone mciSendString("open new Type waveaudio Alias recsound", "", 0, 0); mciSendString("record recsound", "", 0, 0); 2. Under Save / Stop button Click, // stop and save mciSendString("save recsound c:\record.wav", "", 0, 0); mciSendString("close recsound ", "", 0, 0); Computer c = new Computer(); c.Audio.Stop(); 3.

Hi Javed, Below is the code for what you were looking for. Make sure that you are adding reference to Microsoft.VisualBasic from Add reference window. using System.Runtime.InteropServices; using Microsoft.VisualBasic; using Microsoft.VisualBasic.Devices; [ DllImport ( "winmm.dll" , EntryPoint = "mciSendStringA" , CharSet = CharSet .Ansi, SetLastError = true , ExactSpelling = true )] private static extern int mciSendString( string lpstrCommand, string lpstrReturnString, int uReturnLength, int hwndCallback); private void Record() { mciSendString( "open new Type waveaudio Alias recsound" , "" , 0, 0); mciSendString( "record recsound" , "" , 0, 0); } private void SaveRecordedSound() { mciSendString( "save recsound c:\record.wav" , "" , 0, 0); mciSendString( "close recsound " , "" , 0, 0); Computer computer = new Computer (); computer.Audio.Stop(); } private void Play() { Computer computer = new Computer (); computer.Audio.Play( "c:\record.wav" , AudioPlayMode .Background); } Regards, Raaj
