SQL Adapter Not Filling Or Erroring Out?
Feb 16, 2012
I have an app that coonects to 2 different DB servers using the same code but different connstrs to fill in a Combobox. On a certain Pc the first combo fills in and the 2nd does not.It never timesout and no error msg is ever rpted back. It just sits there forever after the adapter.fill cmd.Only difference between the first combo fill and the 2nd is a different connstr.Only 12 rows should come back from the Db. I have connected to Db in SQL query window and ran the SQL cmd and the 12 rows come back in a second or 2.On other PCs this same app works fines. I have the PCs on the same OS and all the newest updates installed.I have tested the network ports, used different ones. Used different user log ins on the same PC. It just wont work.

[code]when I run my program and press this button Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles exceptionsButton.Click..I have my date range within a time that I know that my dataset should produce a result, but when I put a line break in my code here: adapter.Fill(ds)and look at it in debug, I show a table value of 0. If I run the same query that I have to produce these results in sql analyser, I see 1 result. Can someone see why my query on my form produces a different result than the sql analyser does? [code]I can also verify that the variables are passing the correct values. Can anyone please assist as to why this isnt working?

I have a need to figure out which adapter is used when a connection is created. In other words, if I have multiple NIC cards (i.e. wireless, lan, etc) on my machine, which card is being used for the connection?
If anyone can point me in the right direction...

To get an id value after a table insert into an Access database you do a SELECT @@IDENTITY. I would like to know if this will work if your INSERT query is a table adapter query? I created an INSERT query for a table in the dataset designer which is working. My concern is that if I make another query with SELECT @@IDENTITY it won't work because table adapters make a new connection each time. Can someone clear me up on this?

They appaear in the XSD designer but for some reason are not filling the form when it loads. I the form is writting to the backend correctly via hand coded SQL.

I have code in vb.net that was created using Visual Studio 2008. It has got queries done via data sets and table adapters. dsStagMyfileDesigner.vb and dsStagMyfile.xsd are the files having all the sql queries. They are code generated by using data table adapters I believe. Editing them might screw the system.

I'm currently trying to create a system which stores different cases for clients using Visual Studio 2010.When adding fields from the database a table adapter is automatically created.Me.TblMattersTableAdapter.Fill(Me.MJPAccessDataSet.tblMatters)Now my problem is that each case may be at a different stage. They are either 'Active', 'Closed' or 'Archived'.So my question, is there a way to filter these results? I've tried creating DataTable and only adding the archived cases but I couldn't get it to work. I was trying.

I currentt have three tables, using a table adapters and datagridviews I would like to add a new record to each table. the only problem is that the primary key from table 1 is a foreign key in table 2 and 3. Is there a way to add a new record in the table adapter without sending it to the DB and get a predicted primary key so I could put this as the foreign key in tables 2 and 3.

How can I specify which adaptor to begin listening on?
I have an application running on a PC which happens to have 2 network adaptors running on different subnets (one network for Business LAN infrastructure, one for TCP cameras)
I have a class which opens up a TCP server and listens on a specific port for connections coming in from clients on the LAN.
The problem is that my TCP server class initialises and begins listening on the adaptor which is connected to the cameras. Any connection request coming in from the Business LAN fails, it is not dealt with.
The question is, How can I specify which adaptor to begin listening on?
Code excerpt below (this is not the full class, just key methods)
Public Sub New(ByVal Name As String)
'get config
_bootStrap = New TCPServerBootstrap(Name)

How can I control what is filled into the table adapter at runtime? Basically, I have a table full of thousands of rows, and I want to limit this to just 1 row. I want to specify an ID number and be able to pull up that row in the table, and I need to do this at run time. What are my options, and what is the easiest way? I want to make sure the data is still linked to the original row in my database, that way the changes are saved properly.

I'm confused with this piece of code listed below. This code calls the update method of the dataadapter object to save the changes made to the dataSETback to the database itself. What I don't understand about this code is that it creates an update command(cmdUpdate), insert command (cmdInsert) and delete command (cmdDelete). My understanding is that the update method saves the changes back to the database. So I don't understand why the author creates these additional commands.
