Moving a captured bitmap picture across a LAN nework in vb.net

[danielzee]

i am a writing a program to captured a bitmap from one computer and send it to another computer on a LAN network

the problem is that i alway get a prefect first bitmap pic on the picturebox on the client computer but one that follows it will be distorted with the first images

i tried flushing nothing works

 

 

this the server code fragment

 

Public Sub CaptureImage()
Dim data As IDataObject
Dim bmap As Image

'---copy the image to the clipboard---
SendMessage(hWnd, WM_CAP_EDIT_COPY, 0, 0)

'---retrieve the image from clipboard and convert it 
' to the bitmap format
data = Clipboard.GetDataObject()
If data Is Nothing Then Exit Sub
If data.GetDataPresent(GetType(System.Drawing.Bitmap)) Then
'---convert the data into a Bitmap---
bmap = CType(data.GetData(GetType(System.Drawing.Bitmap)), Image)
'---save the Bitmap into a memory stream---
bmap.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp)
'---write the Bitmap from stream into a byte array---
Image = ms.GetBuffer


End If
End Sub

 

this the client code

 

Public Function ReceiveImage() As Boolean

Try
Dim counter As Integer = 0
Dim totalBytes As Integer = 0
Dim bytesRead As Integer = 0
Do
'---read the incoming data---
bytesRead = nws.Read(data, 0, client.ReceiveBufferSize)
totalBytes += bytesRead
'---write the byte() array into the memory stream---

s.Write(data, 0, bytesRead)
counter += 1
'Loop Until totalBytes >= SIZEOFIMAGE
Loop Until totalBytes >= SIZEOFIMAGE

'---display the image in the PictureBox control---

i += 1

Select Case i
Case 2
PictureBox2.Image = Image.FromStream(s)

End Select

PictureBox1.Image = Image.FromStream(s)
PictureBox1.Refresh()
nws.Flush()
s.Flush()
client.Close()

Where on the client is the variable s declared and is it ever needed outside of this method?

 

If you declare the memory stream within this one method and create a new instance for each call it might solve the problem.

Rats! I was really hoping this thread would answer a similar question I have.

 

Looks like I'll have to actually post my question as a new thread, though.
