creating a picture through memorystream

hi all!

other question... how can i create a picture from a memorystream?
i.e. my memorystream contains the data for the image.fromstream property. the memorystream is writen like

file = rs("picture").Value 'dim file() as byte
memoryStream.Write(file, 0, file.Length) ' Dim memoryStream As New IO.MemoryStream()

ok, now i am loading my picture control like

memoryStream.Position = 0
PictureBox1.Image.FromStream(memoryStream)

and that doesnt work. i get always a message "invalid parameter"
what is there wrong??
PLEASE give me any suggestions you have...thx a lot

Is there really no person who migth know the answer? :confused:

Here is a command button that loads a Bitmap from a file, coverts it into an Array of Bytes, converts the Bytes into a memory stream, and then converts the memory stream into an image.

Seems to work. Does this help? The question I have now is how to you draw one bitmap and then extract multiple bitmaps from that.

I.E. have one FileStream that connects to one large bitmap, covert it to bytes, and then extract the bytes of individual images within the image, and produce smaller image streams from that. Anyone have any code for that?

Code:

---

    Private Sub cmdDraw_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdDraw.Click

        Dim oStream As New IO.FileStream(Windows.Forms.Application.StartupPath & "\" & "space.bmp", IO.FileMode.Open)
        Dim bByte() As Byte

        ReDim bByte(oStream.Length)

        oStream.Read(bByte, 1, UBound(bByte))
        oStream.Close()
        oStream = Nothing

        Dim oMem As New IO.MemoryStream(bByte, 1, UBound(bByte))
        Dim oImage As Image

        oImage = System.Drawing.Image.FromStream(oMem)
        Me.BackgroundImage = oImage

    End Sub
