Hello! (VS 2005 VB)

I have an Access DB one of the fields is BLOB, which may contain documents or images. I found examples how to obtain bmp images from BLOB fields like this(works perfect):

Array.Copy(BLOB, 78, imgbytes, 0, BLOB.Length - 7

Dim strmImage As New MemoryStream(imgbytes)

ImageFile = Image.FromStream(strmImage)

Clipboard.Clear()

Clipboard.SetImage(ImageFile)

' paste into the RichTextBox control

Me.RichTextBox1.Paste()

But this doesn't work for any other type of documents.

I tried to read doc, xml into a disk file, and after that show it with WebBrowser, but the file is really corrupted. Seems that I must to cut some bytes from BLOB or may be add. That's what I did for xml or doc:

stream = New FileStream( _

FileName, FileMode.OpenOrCreate, FileAccess.Write)

writer = New BinaryWriter(stream)

writer.Write(BLOB)

Me.WebBrowser1.Navigate(FileName)

But the file is corrupted. Please help.

RichTextBox changes some special symbols to "space". That is your problem.
