Binding a Data Reader in Windows Forms

[ChrisE]

It sounds like you have executed that code twice, thus attempting to bind to the Text property of TextBox1 twice.

nope
there is Textbox1 and Textbox2

but I think I found the fault, it seems that Access 2000 can't handle it (only 2 Clients left with that antique)
it works with every other Access 2003 and up
SqLite etc....
