Steps to Reproduce

  1. Create a new Standard EXE project.
  2. Add a Microsoft Multimedia (MCI32.OCX) control to Form1.
  3. Add the following code to Form1.

          Private Sub Form_Load()
              ' Set properties needed by MCI to open.
              MMControl1.Notify = False
              MMControl1.Wait = True
              MMControl1.Shareable = False
              MMControl1.DeviceType = "WaveAudio"
              MMControl1.filename = "C:\temp\test.wav"
    
              ' Open the MCI WaveAudio device.
              MMControl1.Command = "Open"
          End Sub
    
          Private Sub MMControl1_StopClick(Cancel As Integer)
              MMControl1.Command = "Save"
              MMControl1.Command = "Close"
          End Sub
    
                            
  4. Run the application (Press F5).
  5. Click the Record button, then wait for a few seconds.
