Hi experts,
I have stored an image in clipboard. Now i want to read the image byte by byte so that i can break it into pieces and send it over the tcp/ip based network to another station, where this station will re-assamble the data and display it in its image box or picture box.
Thanks in advance

Thanks for the example but in this case u are reading the filesize from the disk. In my project i have captured the image using bitblt and do not want to save it since saving the file i.e., disk I/O is slow. I will be capturing the image in a timer event so lots of images in maybe 5-10 to 15 seconds of time.
waiting for a reply.
thanks a mil
regards,
msa.
Dear anthonyc,
This is exactly the problem i am facing. I do not know how to address the memory (DC). That is why i tried to place the img in the clipboard - assuming i might be able to access the clipboard memory. Listed below is the code of my cliping the image:
Sub CopyScreen(canvas As Object)
Dim screendc&
canvas.AutoRedraw = True
screendc = CreateDC("DISPLAY", "", "", 0&)
tempLong = StretchBlt(canvas.hdc, 0, 0, Screen.Width, Screen.Height, screendc, 0, 0, Screen.Width, Screen.Height, SRCCOPY)
tempLong = DeleteDC(screendc)
canvas.AutoRedraw = False
End Sub
Private Sub Timer1_Timer()
CopyScreen Me
Me.Caption = "Icu Uc Me - " & Counter
Counter = Counter + 1
End Sub
regards,
msa.
