Steps to Reproduce
- Create a new Standard EXE project.
- Add a Microsoft Multimedia (MCI32.OCX) control to Form1.
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
- Run the application (Press F5).
- Click the Record button, then wait for a few seconds.
