Const WM_CAP_EDIT_COPY = WM_CAP_START + 30
'The first step is to recognize that the video captured by the web cam can be saved as individual images. By displaying a series of continuous images on the client, it is similar to watching a video stream. To capture an image, I have defined the following subroutine:
'---save the video data into the Image global variable---

Dim bmap As Image
Dim ms As New IO.MemoryStream()
'---copy the image to the clipboard---

The problem is the code fail to retrieve the image from clipboard? What I'm trying to do is connect to a webcam, then save the video stream file on this webcam as bitmap file before transfer to the client side as an array of bytes.

Basically i am using a Network Stream to send messages from the client which go through the network to the server which bounces them to the listener which then reads the message and tells the app what to do.
