System.Data.OleDb.OleDbException: 'Syntax error (missing operator) in query expression '=1-'.'/
I got an error message in the code below:
Imports System.Data.OleDb
Public Class Form2
    Private Sub Bts_Click(sender As Object, e As EventArgs) Handles Bts.Click
        Dim conn As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\monja\Documents\Database7.accdb")

        Dim cmd As New OleDbCommand(" select RoomName, Location, Information from table1 where=" + TBs.Text + "", conn)
        Dim myreader As OleDbDataReader = cmd.ExecuteReader


        TBr1.Text = myreader("Location")
        TBr2.Text = myreader("Information")
    End Sub
End Class

What I have tried:

I checked the MS access database. And I googled.

Try a query like this:
SELECT RoomName, Location, Information from table1 where Location=1

and use parameterized queries, otherwise your code will be vulnerable to SQL injection attacks.

This is a bigger problem than you thought ...

Never concatenate strings to build a SQL command. It leaves you wide open to accidental or deliberate SQL Injection attack which can destroy your entire database. Always use Parameterized queries instead.

When you concatenate strings, you cause problems because SQL receives commands like:
SELECT * FROM MyTable WHERE StreetAddress = 'Baker's Wood'
The quote the user added terminates the string as far as SQL is concerned and you get problems. But it could be worse. If I come along and type this instead: "x';DROP TABLE MyTable;--" Then SQL receives a very different command:
SELECT * FROM MyTable WHERE StreetAddress = 'x';DROP TABLE MyTable;--'
Which SQL sees as three separate commands:
SELECT * FROM MyTable WHERE StreetAddress = 'x';
A perfectly valid SELECT
A perfectly valid "delete the table" command
And everything else is a comment.
So it does: selects any matching rows, deletes the table from the DB, and ignores anything else.

So ALWAYS use parameterized queries! Or be prepared to restore your DB from backup frequently. You do take backups regularly, don't you?
