Tableadapters Are Not Appearing In Toolbox

Dec 17, 2011

I added few new tables on data sheet (file name nwinddata.xsd) but the new added table adapters does not appear in toolbox whereas the old adapters were appearing. I read somewhere and followed their advice to delete the project and re add the project to the solution explorer, did that, now i can't even see old adapters in tool box all gone.When i restored my backup old adapters appear in toolblx but few days of will be lost which i don't want.

Using Update With TableAdapters?

Sep 2, 2011

When a person makes changes on my datagridview and closes it, I want it to automatically go into the database and update in a new column (which is already been created) the text "changed".

Everything in my tableadapters already works. Its just the VB part which I dont know how to call the update command. Here is what I have in my updatedataset().

Private Sub UpdateDataSet()
Dim datasetChanges As datasetTs = New datasetTs
Me.bindingsourcet1.EndEdit()

Retrieve A List Of Tableadapters?

Dec 14, 2009

Most of my programs use table adapters, and the connection strings are stored in app settings. This works fine, but was a real PITA when switching from development to production environment. I had to change manually the connection strings before and after starting my work on any app.

After a bit of research I found how to switch connection strings for table adapters dynamically. By simply adding a custom property for connectionString, I was able to acheive this. But I still have to add code in the new event for each application so the connection strings get switched when it loads. (My connection strings are kept as an app property setting in a common DLL. I just keep one copy of the DLL with my connection strings locally, and one copy o the DLL with the production connection strings on the production server.)

I'd like to take this one step further and have either have the datasets change the connection strings for all table adapters they each contain when they load using the new event, or do the same from a VB module. I may have up to 3 datasets at any one time.

VS 2010 Is There A Limit To TableAdapters?

Sep 11, 2011

Cause I just dont get whats going on here. I have a bunch of combo boxes linked to their own Tables in my database, 14 in total. My problem is that only 13 of them work and every one I add after 13 doesnt work for some reason.So I make a ComboBox, press the arrow in the upper right corner and click "Use Data Bound Items", Then I fill in the rest as it should be. But only the "Selected Value" function actually works. I can fill in data to my other tables manually through this ComboBox, but I can not view my Data Source! If I use the same ComboBox and use any other Table it works, but not anything past my 13th table. The BindingSource is there, so is the TableAdapter. If I preview a select quary to the database it works as it should. But for not in the ComboBox!

Its driving me mad, can someone explain to me what might be going on here?

ADO - Best Practices When Using Tableadapters, Sql Connection Strings

May 2, 2010

I have read and worked through all of the examples in the book "ADO.NET 2.O", but there is so much there with so many ways to handle data, I am having difficulty translating the examples into my own real life application. I am confused about creating runtime connection strings, connection strings in my app.config file, connection strings in the properties for a sql connection control, etc.

I have a midichildform with a datagridview control, and I use a table adapter to edit and update the SQL Server 2005 Express edition database. There is no problem there. However, I also have a button control that I want to use to "process" the data that has been updated with the table adapter. I want to open the updated table, read each record on at a time, manipulate the data and add a records to another table. Do I have to create a connection string and an oleDBconnection? Or can I somehow use the connection string that is in my app.config file? [Code]

Moving TableAdapters Out Of The Main Form?

Feb 24, 2009

I'd like to keep all my SQL data related code in a separate class and only have UI related code in my main form. However, the TableAdapters are automatically placed on the main form and, of course, the auto-generated code placed in the Form_Load event.

Obviously, it's easier to keep it like that but is it possible to move them to a different class?

Ascertain If The Tableadapters Underlying Data Has Changed?

Aug 3, 2011

I am retrieving data from my database using a TableAdapter. I was wondering if there is some way I can tell (or be informed) that the data has changed and I therefore need to do another Fill? That way I can just Fill on demand rather than every time the user requests to see the information and I am forced to do a Fill before showing the data because I don't know if is current or not. For the record I am using an ODBC connection string to access a Pervasive PSQL database

EDIT I was thinking I could check the last write time of the MKD file to check if this has changed but this doesn't seem to be reliable as it is not written to until the connection is closed. Does anyone know the circumstances when this is written?

VS 2010 Access Database + TableAdapters: Return Last ID?

Nov 15, 2010

I am using an Access database (mdb file) and for the first time ever I'm connecting to it using a bunch of TableAdapters created in a DataSet.xsd file.I added an Insert query to a TableAdapter, and now I need to retrieve the ID (autonumber) of the last inserted record. Usually, I would send a "SELECT SCOPE_IDENTITY()" query and it would return the ID, but for some reason I cannot get this to work with the TableAdapter.

I tried two methods:1. Add the SELECT SCOPE_IDENTITY() query directly after the INSERT query in the TableAdapter. This method is described in every website I found by googling my problem. Suppose my INSERT query is this:

INSERT INTO Test VALUES("1", "2", "3")
then I should now modify it into
INSERT INTO Test VALUES("1", "2", "3");
SELECT SCOPE_IDENTITY()
I also changed the ExecuteMode to Scalar.

Ok, I run this code, but it doesn't work. It gives me an error saying Characters found after end of SQL statement.Is it because I am using Access and not SQL Server maybe? I dunno... But whatever I try it doesn't work. It's not a spelling error, and I did type the semicolon to separate the two queries so as far as I know it should work.2. Add a separate Select query (selected 'Select query that returns a single value' in the designer) that simply executes this:

SELECT SCOPE_IDENTITY()Then after using the Insert query I can simply call this query method and get the last Id. But unfortunately this doesn't work either. It doesn't even let me add this query in the designer, it says Unable to parse query text.

Unable To Connect To Database Using Both Tableadapters.fill & Sql Code

Mar 27, 2011

Running off my laptop: Visual Basic 2010 Express & SQL Server 2008 . I've successfully been able to use the connection wizard to connect to my database in vb.net and read/write data using datasets/tableadapters/binding_source etc.

Now I am trying to create an SQL connection via code to connect to my database to do some more complicated queries. I was successful in being able to connect to my database with SQL, but by doing so it produces an error when it tries to run any .Fill() methods from my TableAdapters below. The error produced is the following: "SqlException was unhandled. Cannot open user default database. Login failed. Login failed for user 'Chris-PCChris'".

If I remove my SQL connection code, the TableAdapter.Fill() methods will work fine.

VB6 Used Recordsetsor Arrays - .Net Framework In VB2010. Datasets, Dataviews. Tableadapters, Arrays. Enums ?

May 9, 2010

In VB6 I load a recordset containg all of the records (6 fields per record)in a table into an XArray and then manipulate the records in the array and then write them back to the original table. The array issorted by the first field (1 to maybe 8000 or more) I need to find records in the array by an ID field and then move them (because of some external criteria that happens many times) from say number 400 to number 375. Then all of the other records between 375 and 399 were renumbered up 1 to fill the gaps left by the move.

The XArray worked well as it could find and also move to a next record easily to facilitate the revisions to each record quickly. Everything is done in VB6 in code and nothing visual needs to be shown to the user until say 2000 of these external changes are complete. What is the best, most efficient way to do this in the .Net framework in VB2010. Datasets, Dataviews. tableadapters, arrays. enums ?

Button Not Appearing When App Built?

Nov 3, 2011

I have a problem where a button at the top left of a tab control will not appear in debug or compiled. There is no code telling it to hide.

Now, I can make it re-appear by moving it, then moving it back to the exact same position. If I then re-build it will be there.

It will then be there for a number of builds, at which point it might disappear again. This seems to happen for a few buttons in my project. The common factors are that they are on a tab control (standard dot net ctrl) and near the top left of a tab page.

Appearing To Change Controls On A Form?

Aug 31, 2010

VBExpress 2010 .Net 4.0 I'm trying to have a form that you click on a button and it goes to a new page of the same size in the same location. An example of this type of thing would be the different pages of an install wizard. In this particular project, I have an "instructions" page that you click on that takes you to a new form. On this page is a "back" button that takes you back to the main screen. I'm just not sure how this type of thing is normally done. What I have done works, but you can see the page 'flip' a little, and the form button on the taskbar disappears and reappears as the new one loads.

[Code]...

and I have an equivalent subroutine on the other form to get back. At first I had the Three middle line of code interchanged, which looked much smoother, but for some reason it didn't work on the first click, upon which the form would suddenly move to the wrong location, after which it would work fine, no matter where I moved the form.

I have a feeling that this is probably done in a completely different way, but can't think of a better way of doing it. One way would be to just use one form and change the controls instead, but it would get quite cluttered.
