I have a two forms with about 25 bound controls on each in the same solution. All of the data for both forms is in the same SQL table. I need to filter the data and only get the data appropriate to the called form. I consulted an University VB professor and he would only say "it won't be easy".
I tried removing all of the bindings and rebinding them to the new datasource but there were still some remnants (probably from the navigator) that proved illusive.
Is the only solution to recreate the VB forms and bind them to the new datasource?

I have two comboboxes. The data sorce of combobox1 is a list of string that is fixed.Combobox2's data sorce will be a list of string that depends on the selection of combobox1. This is very similar to a common case as follows: first enter your contry, then depending on your enter, the second combobox will show you the list of universities in the country.
'Change selection of first combobox

On SqlDataSource_Insert, I'm grabbing the users unique MemberID and adding to the db. Adding the MemberID works great. I also want to add a unique EventID for the event they are submitting, but the code that I'm using below just inserts a guid with all zeros.

I need to explicitly load my data source variables and then call the insert method associated with the data source. The sample VB .net code is listed below. So is it sufficient for me to just call the Insert() method when I am ready to insert my values? Or do I need to create an insert event? You see if I look at the properties window for the data source, there is a lightning bolt icon that will generate events for the data source such as Insert,Inserting,Disposing,Init,Load etc.

I'm using a MS Access 2007 database. I modified the field definition of one of the fields in a table, it a text field and I change the maximum length from 40 to 150. I have a data source in my app that contains this table and many others. I refreshed the data source but the change didn't take affect. I went through configure option but the change still didn't take affect. It gives me this error,
The value violates the MaxLength limit of this column.
If I add/delete a database field the data source is updated when I go through the configure process. I finally just deleted the table from my data source and then added it back.

I have a project where I added visually and successfully a datasource of MySql. I binded a datagridview with a table.
But, how do I change programatically the password, ip or user to connect with the MySql server? Because it can change at any time, so I can let the user change these values.

I want to create a textbox which contents are validated every time the text in it changes. And an image is displayed beside the textbox if it is correct and another image shows up if its not correct. Pretty much like ajax.
Heres the method which I called from the class.
Public Sub read1()
cmd.CommandText = "SELECT * FROM testdb WHERE Name='" & name & "'"
Try
[Code]....
Problem is, the method seems to be only called once. And the first image that was displayed stays the same even after inputting a data which does not exist in the database. I'm connecting this program to a mysql database using odbc.

I refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.

I have a program on my machine that uses a local SQL Express 2005 database to store information in when the program is running. I want to use some data within said database in my program but for the life of me I cannot seem to get started by adding it as a new data source using the add data source wizard... If I type in the database name it throws an error that it cannot find the database, although I can quite clearly see it using the SQL Express 2005 SQL Server Management Tool.

The code below works well to load an Excel file into a DataGridView. The menu 'Show Data Source' reveals there is no data source available. Is there a way to set up a data source much in the same way as is possible with a .mdb which I would normally add with the menu 'Add New Data'? Several ways to confugure the DataGridView are not options without a known data source.

I am currently working on a project that involves the use of data base sources, namely ODBC. The problem is I have designed a form using the Data Source Configuration Wizard that doesn't update. I've ensured that I have a primary key in my data and that the Copy to output is set to "Copy Always". The code generated by the wizard, is as follows: Public Class Form1

I have downloaded and run the mysql-connector-odbc-5.1.5-win32.msi. The wizard goes through the process but when I go to vs 2008 and try to Add a Data Source or Show Data Sources I get a blank. NOTHING! Just like I had not clicked on the command. There are simply no data sources available in this virgin copy of Visual Studio 2008. I cannot even access an access db!

I am working on a app that will monitor the registry for changes to [ProviderOrder] in [SYSTEMCurrentControlSetControlNetworkProviderOrder].
I have it 90% done with this
Imports System.Management
Imports Microsoft.Win32
Module Module1
Dim Watcher As ManagementEventWatcher
Dim Hive As RegistryKey = Registry.LocalMachine
[Code] .....
If I change [ProviderOrder.test] the app tells me the value was changed and corrects it. But it does the correction twice (because of UpdateProviderOrder changing the value). I thought that using RemoveHandler and AddHandler would take of that.

I have been trying for days now how to create a process to the user to easily create a connection to any installed data types they have installed. I have found an example right inside vb2008. I never use this because I code my own connections, but this would be real nice if I could include it or duplicate it.

I want to include the ability for the end user to create connections to different databases using the same (or similar) dialogs that are available at design time, such as the Connection String builder, Selection Data Source (ODBC) screen, etc. Is this something built into .NET or only available via third party/custom controls?
