Hola soy nuevo en el foro y quisiera saber si me pueden ayudar.
Mi problema es que quiero enviar una captura de pantalla por un winsock, pero me sale el error 521 Can't open clipboard.
Este es el codigo:

Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)

Private Function Capturar()
    Clipboard.Clear
   
    keybd_event 44, 0, 0, 0
    keybd_event 44, 0, KEYEVENTF_KEYUP, 0

    Do While Clipboard.GetData = False
    DoEvents
    Loop

    pant.Picture = Clipboard.GetData
    Clipboard.Clear
End Function

Private Sub capt_Timer()
    If ws.State = sckConnected Then
        Capturar
        ws.SendData pant.Picture
    End If
End Sub

Private Sub Form_Load()
    ws.Listen
End Sub

Private Sub ws_ConnectionRequest(ByVal requestID As Long)
    ws.Close
    ws.Accept requestID
End Sub

Private Sub ws_Error(ByVal Number As Integer, Description As String, ByVal Scode As Long, ByVal Source As String, ByVal HelpFile As String, ByVal HelpContext As Long, CancelDisplay As Boolean)
    ws.Close
    ws.Listen
End Sub
