Binary writing of JPG from access problem..

[Ephesians]

I have bmps, gifs, and jpgs stored in my access 97 database. I have no problems binary writing bitmaps and gifs because I know the header point that access adds to the ole field...BM and GIF89 respectively but I can't find the jpg access header in the ole field... can anyone tell me what it is? Here is a sample of the code I'm using to binary write the correct information. You'll see what I mean by the access header..

ExportFile Me.RecordsetClone.Fields("PictureType")
Dim lngFileSize As Long, lngOffset As Long
Dim strChunk As String, strBuild As String, intPos As Integer
 
lngOffset = 0
lngFileSize = 0
lngFileSize = Me.RecordsetClone.Fields("picture").FieldSize
 
Do While lngOffset < lngFileSize
     strChunk = Me.RecordsetClone.Fields("picture").GetChunk(lngOffset, 1024)
     strBuild = strBuild & strChunk
     lngOffset = lngOffset + 1024
Loop
strBuild = StrConv(strBuild, vbUnicode)
intPos = InStr(strBuild, "BM")  '<--- I need the header for a jpg file
 
If intPos > 0 Then
     strBuild = right(strBuild, Len(strBuild) - intPos + 1)
End If
 
Open strFilename For Binary As #1
Put #1, , strBuild
Close #1

JFIF i believe. you really only need to extract the first 10 bytes of the file.

Nevermind.. I figured it out.. there is no header code for a jpg.
