Hi, just try to create application using VB6 for my kids, but facing problem with image on how to save & retrieve it from MS access database. could you guys please share the code. TQ in advance.

Thanks for opening your own thread amrahim, it is much appreciated.

Below should do the trick for you, just add the controls as needed.

Option Explicit

Private Declare Function GetTempPath Lib "kernel32" Alias "GetTempPathA" (ByVal nBufferLength As Long, ByVal lpBuffer As String) As Long
Private Declare Function GetTempFileName Lib "kernel32" Alias "GetTempFileNameA" (ByVal lpszPath As String, ByVal lpPrefixString As String, ByVal wUnique As Long, ByVal lpTempFileName As String) As Long

Hope this helped.

It's a pleasure. Don't forget to please mark this thread as solved if it worked for you. This way we will ensure that it is closed properly, thanks.

maybe my pc or vb6 on my pc have problem. I cannot use adodb. before, I use it to retrieve image from file (image not in database) and its work. Try to do something with this PC before I mark this thread as solved, unless I'm very sure the code is working for me. Thanks.
