Hi Aaron,

Do you mean remove " Inherits System.Windows. Forms.Form" ??

I am not familiar with VB.NET, I need your more description.

Best regards,
Boki.

Boki,

Strange, can you try to describe it as this to see what happens.
Dim cn As System.Data.Ole Db.OleDbConnect ion
Dim cmd As System.Data.Ole Db.OleDbCommand
Dim dr As System.Data.Ole Db.OleDbDataRea der
...


Your code should not give an error in my opinion.

I will get error when I add this line:

Imports System.Data.Ole Db

Did I miss some LIB or?

Best regards,
Boki.

Boki,

You can see that in your solution explorer at resources.

If it is not there you can rightclick on that and than Add Reference and
follow the box that you see or use Project Add Resources.

I hope this helps,

Hi,
I can read a MS ACCESS file in WIN32 app project, but I failed on WINCE
project.

Q1. First, I want to read/write MS ACCESS file in WINCE, it works only
on WIN32 app project now... ( if I want to read MS ACCESS file, I still
have to inlcude "System.Data.Sq lserverce.dll"? )

Q2. I want to read/write SQL data, so what I have to do is include
"System.Data.Sq lserverce.dll" ? and then I will have the most
functions?

Thank you so much for your advice for newbie.

Best regards,
Boki.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
