captura de pantalla lista pero con un detalle...

[cadrogui]

me encontre este code navegando y me han surgido unas dudas, como puedo hacer que al capturar la pantalla mediante winsock (estoy trabajando en una aplicacio cliente-servidor) el servidor me envie la captura de pantalla que realizo pq el cliente recibe la instruccion de capturar, ese no es problema pq yo lo hice, lo que me tiene loko es lo del envio de la imagen. como puedo hacerlo....

lo estoy tratando asi..

este es un code del servidor....

*************************************************
Case "screen2": Set Picture1.Picture = CaptureScreen()
Dim imagen As PictureBox
Winsock1.SendData imagen
**************************************************


bueno y en el server lo estoy tratando de recibir asi...

**************************************************
Private Sub Winsock1_DataArrival(ByVal bytesTotal As Long)
On Error GoTo error
Dim datos As String
'Text1.Text = Text1.Text & Chr(10)

Winsock1.GetData datos
Text2.Text = Text2.Text + datos & vbCrLf

Dim imagen As PictureBox
Winsock1.GetData imagen
Picture1.Picture = Picture1.Picture + imagen


Exit Sub
error: MsgBox "Error Recibiendo datos.", vbCritical
End Sub
************************************************** *

' Visual Basic 4.0 16/32 Capture Routines

' This module contains several routines for capturing windows into a

' platforms.
' The routines also have palette support.
'
' CreateBitmapPicture - Creates a picture object from a bitmap and
' palette
' CaptureWindow - Captures any window given a window handle
' CaptureActiveWindow - Captures the active window on the desktop
' CaptureForm - Captures the entire form
' CaptureClient - Captures the client area of a form
' CaptureScreen - Captures the entire screen
' PrintPictureToFitPage - prints any picture as big as possible on
' the page
'
' NOTES
' - No error trapping is included in these routines
