DataGird and convertion VS 1.0 and VS 1.1

P: n/a
Hello

I made small GUI test program in Visual Basic NET for SQL
communication. I need some help with these problems.

problem 1)
If I change some settings in datagrid from
properties window (e.g. background color). my datatest is
removed. I compared it with diff program and it
reorganized all source code.
problem 2)
When I open project in VS.NET 2003, it asks for
some conversion. After this conversion project is not
working any more (Datagrid shows empty results and there
are some other wornigs).

Question 1)
Is it ok to split wizard code this way or is there
another recomendet method

Question 2)
Is it possible that there is some know problem
with project's conversion between VS 1.0 and VS 1.1. Or is
it caused by my code design.
Project uses Datagrid and SQL connection (connector and
dataset). I genarated the connection with data wizard. I
splitted this generated code into two parts. An unvisible
part of the connection is in dll library, it means these
variables and there initialisation.
Public Class iceMain
Public WithEvents SqlDataAdapter1 As
System.Data.SqlClient.SqlDataAdapter

Me.SqlDataAdapter1.TableMappings.AddRange(New
System.Data.Common.DataTableMapping() {New
System.Data.Common.DataTableMapping("Table", "uzivatele",
New System.Data.Common.DataColumnMapping() {New
System.Data.Common.DataColumnMapping("userID", "userID"),
New System.Data.Common.DataColumnMapping
("uzivatelskeJmeno", "uzivatelskeJmeno"), New
System.Data.Common.DataColumnMapping("heslo", "heslo"),
New

...

A grid control is in test application that use exported
dataset from dll.
....
Me.DataGrid1.DataMember = "uzivatele"
Me.DataGrid1.DataSource = mCman.DsUzivatele1
<======= (removed by wisual editation)
Me.DataGrid1.HeaderForeColor =
System.Drawing.SystemColors.ControlText
....

Thank you

I am not sure what you are saying about splitting the code. Are you modifying the code in the Wizard generated code section of the form? If so then yes, it will change everytime
you even add a control much less change versions. I have upgraded a couple of projects with a datagrid from 1.0 to 1.1 with no bad effects.
Want to know more? Check out the MSDN Library at http://msdn.microsoft.com or the Microsoft Knowledge Base at http://support.microsoft.com
