Extracting image in databases using DAO 3.5 (Access DB)

I have been trying to store images in a database for sometime, i can do it directly from Access97 but i can't transfer these image to any control in VB.

What i'm really doing is, i store the images for my toolbar buttons in a database so that the user can edit them and the changes will be kept. So what i need to know, is how do i extract and how do i update images directly from a ole-Object field in an Access 97 Database using DAO 3.5 (or 3.6, i got that one also, but i don't have the help file so i'm using 3.5)

Hi, try my code at

These messages you found was sent last year :) and I have now new great site but unfortunately only for russian speaking people :) Here is the code you request:

Code:

---

Dim dbTest As Database
Dim rstAlbum As Recordset
Dim FileLen&, X%, lngOffset&, Chunks%, lngTotalSize&
Dim Arr() As Byte
Const ArrSize As Integer = 16384

Sub ReadPictureFromDb()

On Error Resume Next

Open "d:\picture.gif" For Binary Access Write As #1
lngTotalSize = rstAlbum!Picture.FieldSize
Chunks = lngTotalSize \ ArrSize
Fragment = lngTotalSize Mod ArrSize

ReDim Arr(ChunkSize)
Arr() = rstAlbum!Picture.GetChunk(lngOffset, ArrSize)
Put #1, , Arr() lngOffset = lngOffset + ArrSize

With rstAlbum

Do While lngOffset < lngTotalSize
Arr() = !Picture.GetChunk(lngOffset, ArrSize)
Put #1, , Arr()
lngOffset = lngOffset + ArrSize
Loop Close #1
.Close

End With

End Sub

Sub SavePictureToDb()

rstAlbum.AddNew

Open "c:\picture.gif" For Binary Access Read As #1

FileLen = LOF(1) Chunks = FileLen \ ArrSize Fragment = FileLen Mod ArrSize

ReDim Arr(Fragment)

With rstAlbum Get #1, , Arr()

!Picture.AppendChunk Arr()
ReDim Arr(ChunkSize)
For I = 1 To Chunks
Get DataFile, , Arr()
!Picture.AppendChunk Arr()
Next
Close #1 .Update

End With

End Sub

Private Sub Form_Load()

Set dbTest = OpenDatabase("d:\db1.mdb", True)
Set rstAlbum = dbTest.OpenRecordset("select * from Album", dbOpenDynaset)

SavePictureToDb
ReadPictureFromDb

Set rstAlbum = Nothing
dbTest.Close

End Sub

Have a nice day,
