Retrieve Image from Access DB to ImageControl in Form

Mar 19th, 2009

hi everyone, i have successfully saved the image file to DB by this code:

Private Sub cmdSave_Click()
Dim picsm As ADODB.Stream
Set picsm = New ADODB.Stream
picsm.Type = adTypeBinary
picsm.Open
picsm.LoadFromFile filepath
With rs
.AddNew
.Fields("Last") = txtLast.Text
.Fields("First") = txtFirst
.Fields("Pic") = picsm.Read
.Update
MsgBox "Successful"
End With
picsm.Close
Set picsm = Nothing
End Sub

But anyone can help me retrieve this image from DB and load it into the IMAGE CONTROL on the form?

i have this code:

Private Sub cmdSearch_Click()
Dim photo As String
squery = "select * from tblpic where Last='" & txtLast.Text & "'"
photo = rs.Fields("pic")

Set cm = New ADODB.Command
With cm
.ActiveConnection = conn
.CommandText = squery
.CommandType = adCmdText
End With
Set rs = New ADODB.Recordset
With rs
.CursorLocation = adUseClient
.CursorType = adOpenStatic
.LockType = adLockPessimistic
.Open cm
End With
With Me
.txtLast = rs!Last
.txtFirst = rs!First
.imgPic.Picture = LoadPicture(App.Path & "\pic\" & photo)
End With
End Sub

here is the error:

"file/path access error."

how could i retrieve the picture in the Access DB,
i think a folder must be reserved for the location of the photo.

thanks for the response.
