I have followed every step in the My Sql forum posted - http://dev.mysql.com/tech-resources/articles/vb-blob-handling.html.

I have no problem in saving the picture file to MySql. The problem arises in retrieving the picture.

I am using code as follow: -

Private Sub DataLoadPicture()
    
On Error GoTo ErrFailed
    
Dim cnPhoto As New ADODB.Connection

Dim strIP As String

strIP = txtServerIP.Text

cnPhoto.ConnectionString = "DRIVER={MySQL ODBC 3.51 Driver};" _
            & "SERVER=" & strIP & ";" _
            & "DATABASE=ADMS;" _
            & "UID=root;" _
            & "PWD=;" _
            & "OPTION=" & 1 + 2 + 8 + 32 + 2048 + 16384

cnPhoto.CursorLocation = adUseClient
cnPhoto.Open
    
Dim rsPhoto As New ADODB.Recordset

Dim mystream As New ADODB.Stream
mystream.Type = adTypeBinary

rsPhoto.Open "SELECT * FROM employee WHERE employee.NewEmpNumber = 250", cnPhoto ', adOpenKeyset, adLockOptimistic
    
mystream.Open
mystream.Write rsPhoto!Photo
mystream.SaveToFile "c:\\newimage.gif", adSaveCreateOverWrite

imgPhoto.Picture = LoadPicture("c:\\newimage.gif")

mystream.Close
rsPhoto.Close

cnPhoto.Execute "DROP TABLE employee"
cnPhoto.Close
    
Exit Sub
    
ErrFailed:
MsgBox "The Employee Photo is either not saved or an error occurred in loading. " & err.Description, vbOKOnly + vbInformation, "Error In Loading Photo"
    
Exit Sub
End Sub

rsPhoto is loading correctly, because data is added to the text boxes.

I receive an error "Arguments are of the wrong type, are out of acceptable range or are in conflict with one another" error '3001'

If I take the "Mystream.Write RsPhoto!Photo" out, a file is saved under c:\ with obviously no bytes.

I have tried to change the picture types from jpg, gif to bmp. Again all saves fine, only the retrieval is generating errors.

Any ideas any one please.
