Anyway, Google ("SQL Server 2005" systables) and see if that
points you in the right direction.
There is a view that has a list of all the columns in the whole
database. I believe its information_sys.columns

If you don't know how to use Google, then you need more help than
anyone in this newsgroup is likely to be able to provide.

Your question is very open-ended and it is not clear what you really
want assistance with. Is it running a metadata query in SQL Server? Or
is about data access from VB .Net in general? In the latter case, I would
suggest that you are better off by first learning the basics before you
play with metadata.
Nevertheless, a query you could run to get all tables is this one:
SELECT quotename(schema_name(schema_id)) + '.' + quotename(name)
FROM sys.tables
ORDER BY 1
As for running it from VB - there are many possible variations depending
on what you want to do with the data. Here is a console-mode prorgam that
just prints the table names, and which uses DataAdapater.Fill. It also
includes some error handling.
Imports System.Data
Imports System.Data.Sql
Imports System.Data.SqlClient
Module Bugtest
Private Sub ErrorFill(ByVal sender as Object, ByVal args as FillErrorEventArgs)
Console.WriteLine(args.Errors.Message)
args.Continue = true
End Sub
Private Sub PrintSqlErrors(ByVal errors As SqlErrorCollection, ByVal what As String)
Dim e As SqlError
For Each e In errors
Console.Write (Now.ToString("HH:mm:ss.fff") & " " & what & _
" Message: Msg " & e.Number.ToString() & _
", Severity " & e.Class.ToString() & _
", State: " & e.State.ToString() & _
", Procedure: " & e.Procedure & _
", Line no: " & e.LineNumber.ToString & vbCrLf & _
e.Message & vbCrLf)
Next
End Sub
Private Sub OutputException(ex As Exception)
If TypeOf ex Is SqlException Then
Dim SqlEx As SqlException = DirectCast(ex, SqlException)
PrintSqlErrors(SqlEx.Errors, "Error")
Else
Console.WriteLine(ex.ToString())
End if
End Sub
Private Sub SqlInfoMessage(ByVal sender As Object, ByVal e As SqlInfoMessageEventArgs)
PrintSqlErrors(e.Errors, "INFO MSG")
End Sub
Private Sub PrintDataTable(ByVal tbl As DataTable)
Console.Writeline ("=========================================================" & vbCrLf)
For Each col As DataColumn In tbl.Columns
Console.Writeline (col.ColumnName & vbTab)
Next col
Console.Writeline (vbCrLf)
For Each row As DataRow In tbl.Rows
For Each col As DataColumn In tbl.Columns
Console.Writeline (row(col).ToString() & vbTab)
Next col
Console.Writeline(vbCrLf)
Next row
End Sub
Public Sub Main()
Dim cn As New SqlConnection, _
strConn As String
' This does not help.
' AddHandler cn.InfoMessage, AddressOf SqlInfoMessage
' Connection string, change server and database!
strConn = "Application Name=systablesdemo;Integrated Security=SSPI;"
strConn &= "Data Source=(local);Initial Catalog=AdventureWorks"
Try
cn.ConnectionString = strConn
cn.Open()
Catch ex As Exception
Console.Writeline(ex.Message, "Connection failed!")
cn = Nothing
Exit Sub
End Try
Dim cmd As SqlCommand = cn.CreateCommand()
cmd.CommandText = "SELECT quotename(schema_name(schema_id)) + "
cmd.CommandText &= " '.' + quotename(name) FROM sys.tables "
cmd.CommandText &= "ORDER BY 1"
Dim dt As New DataTable, _
da As SqlDataAdapter = New SqlDataAdapter(cmd), _
no_of_rows As Integer
AddHandler da.FillError, AddressOf ErrorFill
Try
no_of_rows = da.Fill(dt)
Catch e As Exception
OutputException(e)
End Try
Console.Writeline("No of rows filled " & no_of_rows.ToString() & vbCrLf)
PrintDataTable(dt)
cn.Close()
cn.Dispose()
End Sub
End Module

Do you also use it as a search engine?

Thank u for the your reply and the links.
What I really want is too easy and clear :
I create a program that open SQL 2005 Data Bases and show tables of
the data base.
What I have done is to get a table data but I have to know the table
name before opening any one.
What I want is to know the tables name of the current data base.
Any idea ?

I just posted a sample on how to do it. You even reply to that post. Could
you care to explain why it does not address your problem?

Just replace AdventureWorks in the connection string with the database
of your choice. I used AdventureWorks to give you a working sample.

And just to be more specific...
' Connection string, change server and database!
strConn = "Application Name=systablesdemo;Integrated
Security=SSPI;"
strConn &= "Data Source=(local);Initial Catalog= ***** YOUR
DATABASE HERE **** "

Thank you the problem was solved, and I used mid to get the table
name, because the output was "[DBO].[table]"
Thanks again for your help

You could modify the query if you don't want the schema.
Then again, in SQL 2005, it may be dangerous to ignore the schema, since
SQL 2005 makes schemas useful, and it can be deceivable to work with.
The AdventureWorks database is a good example of this.
