Hello,

I am using VB.net and want to record from a Window. Here is my code :

Dim _re As Recorder Dim so As New SourceOptions Dim rs As New List(Of RecordingSourceBase) Dim ro As New RecorderOptions Dim rw = Recorder.GetWindows()

rs.Add(rw.FirstOrDefault()) so.RecordingSources = rs ro.SourceOptions = so _re = Recorder.CreateRecorder(ro) _re.Record("c:\aa.mp4")

No error, but no file is created !

have an explain ?

Thanks a lot

You can subscribe to the OnRecordingFailed event to see the error. But i can guess that you need to run your application with administrator prvileges to write to c:\ root. Or write to a path in the Users directory instead.

Thanks a lot !!! The error was : "Windows Graphics Capture requires Windows 10 version 1903 or greater." !!! It is OK with monitor, but failed with Windows ... Your library is very nice !!!
