I recently created a test VB.NET 2008 project with an Access database and it seems to work okay. It uses a dataset and table adapters. I'm aware that some people don't like table adapters. I'm willing to learn another way if it's better. Should I do this or continue using table adapters?

I have a sql server database file which I have connected to a web service I am writting I have created a table adapter in a datase.t I have created a web method which has parameters for the fields in the database
<web Method> _
function add_record(byval a as integer , byval b as String)
dim ds as dataset
[code]......
How do I do this for a different dataset? I'm trying to rule out database problems so I made another one and added it, but now I need a table adapter for this one instead of the old database because it keeps giving me an error. I don't see any place to add them and I'm getting extremely angry at these databases.
View 1 RepliesYou can iterate the controls collection and me.components.components to find certain objects, but nowhere can I find where a form keeps a collection of its early-bound table adapters. When you add them in at design time and bind them to a control, it shows them on the design window, and it creates them in the design.vb file, and they're available as a property of your form object... but I can't find a way to browse through them and pick one in code, like you can with the control collection (I.E. me.controls.Item("controlname")).[code]...
View 1 RepliesI'm using visual studio 2010 to build my application and SQL server 2005 to store the data. I created a table adapter, dataset and binded the controls to my already made formThing is, i'm trying to insert a new record into the database and it won't work! I can fill the form with a record from the database and update it so i know its definitely connected correctly. Everytime I try to insert a new record whether its through a table adapter or manually, I just can't seem to get it to automatically save to the database.Ive put this under the save button
Private Sub SaveBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveBtn.Click
Dim CustomerRow As accountingdbDataSet.CustomerRow

i am working on a project that stores records from a windows form to an access datbase.But i am having problems with the update statement.I have a form with the fields bound to datatable called LeedsHubInfo .Dataset called LeedHubInfoDataSet1.
Private Sub cmd_save_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles cmd_save.Click
' Create a new row.
Dim newJobRow As leedHubInfoDataSet1.LeedsHubInfoRow
newJobRow = Me.LeedHubInfoDataSet1.LeedsHubInfo.NewLeedsHubInfoRow()

On the update line i get an exception thrown up "A first chance exception of type 'System.Data.OleDb.OleDbException' occurred in System.Data.dll" I thought inserting a record into a database would be easy but i seem to be naking a right pigs ear of it?
Using; - vb2008 Express, data on ACCESS 2003, objective; - to update a separate table not on the original query.From what i have gathered i need to add a second table adapter to make the changes to a related field in another table. Since i already have the 1st table adapter the second does not appear as easy as the second (dragn the data set over).
So i suppose i need to create the second table adapters programmatically? [URL]..I see that because they are not nested they need to each be declared.. right? If so that is where my issue lies. I'm having a problem with how to declare them both now that there must be two.
I would like to know if it is possible for a Table Adapter to reference a query as opposed to a table. Currently my Table Adapter references a table in my SQL database, but I wanted to know if it was possible to have it reference a query, which selects a table from another database?
View 5 RepliesIn a project, I have a dataset with two table adapters. Without warning while I was modifying one of them in design mode, I received this error. I have typed the contents of the dialog box exactly as they appear - so no additional information was given, and the error code was "-1".
View 2 Replies I have a project that I used the 'Connect to Database' tool to set all the bindings and table adapters, etc. Currently the database is housed in the same directory as the exe. I was asked if I could have the database location be a dynamic value. My question is when you set up a project to work with a database using the 'Connect to Database' tool, how can you change its location?
I found this setting:
ASRDBConnectionString
But its read only.
Within that setting is text that says: DataDirectory
So thought that might be a variable to change somewhere....but can't find it.
I have a problem that hopefully someone can shed light on. My OleDBdataadapters and OledbTableadapters have gone on strike In a simple vb.net 2005 pro project I have an Access 2003 .mdb with 2 tables each with 1 primary key and all other fields allowing zero length and not required. The database (not read only) is included in the project (see connection string below which works because data is presented on bound forms).
Although each table's data is displayed on one of 2 bound windows forms, it just refuses to update, add new or delete. I've deleted and recreated forms, etc, using wizards and just run time code but the problem is still there. I can change data manually in the mdb. The code below refers to a site mdb table and was wizard generated. I added an update query to the TableAdapter using the wizard, see sql below.

I have inherited an application at work that someone else started creating, right now about 1/2 of it is functional and is in use. My problem is that it is all done in 2.5 ?? and I am trying to step through it all to figure out how it works. I have always created my own binding sources, adapters and data tables.
One of the things I need to do is add a field to the fm_fieldman_master data table. I add the field in the db (SQL Server 2005)table, I come into VS and refresh the datasource, I then add the field to the fm_fieldman_master data table and the Fill,GetDAta() query I go into the designer and create all the attributes for the combo box

Aim to Achieve : I want to have 3 different dataTables from 3 different SQL queries from 3 different places into 1 single DataSet which I will have to return form my function.I have :
Private Function getDataSet()
Dim ad1,ad2,ad3 As Object
ad1 = New Data.OleDb.OleDbDataAdapter(query1, conStr1)[code].....
I want to use the best possible implementation of above task.
ok normally when i fill data i do it this way adapter.Fill(dataset, "table1") However instead of using Strings, i prefer using enums so for example i have:
public enum Tables
T1
T2
end Enum
but since adapter.fill does not provide an "integer" argument when i add i had to convert it to a string as such adapter.Fill(dataset, cstr(Tables.T1)). i find this "dirty" and was wondering if there is a better fix
I want to write a small program to just enable/disable two network adapters. I searched over google and I found a few C# codes but didn't understand anything. I heard something called WMI. It seems they are other ways like enabling registry (which sounds wierd for me) or using command lines.
I really don't know which way should be used althought I didn't find any code to those either. something that works in win xp & vista & seven.
Because user want two switch between two NIC by enable one and disabling another one, I think I should first get a list of network adapters, then let user specify. I know It can be done easily by going to the network settings directly and do it by right clicking. But they want to do it through a program with single click.
Edit: I was able to get a list of adapters using WMI, Here is the page If someone wanted to take a look.
Im currently making a program. It loads data from database fields into an combo box. Everything works so far, It just seems to be a mess. Do i need to have all the datasets and data adapters? or can i get away with just using 1 of each. It seems like im doing it wrong, and although it works it seems like a difficult and messy way of doing it.
Also i would like to assign the firshermenID to a variable depending on the fisherman name that is selected in the combo box. When button is pressed: id = fishermanID of the current fisherman (cmbFisherman.text)

I recently switched to V.Studio 2008 and using VB. I can not find in the data toolbox the connection and data adapters. Should I do something else to make this appear so I can drag them in my form.
View 2 RepliesI am working on a huge multiform project for my company, and one of the few issues I am having is that when I am on the Main Menu Form, then go into a specific form (i.e Sales Order, etc.), do updates, changes, or just view data then close the Sales Order Form, if I happen to go back into the Sales Order Form without closing the entire project, then the Sales Order Form will display data instead of opening a blank form like when I first opened it.
Is there something that I should be adding to the Form Close Event to dump all of the data or refresh the data adapters so that if I open the form again, it will display a blank form that is ready to be used like when I first opened it?
I have tried using;
Me.Dispose()
Me.Close()
when closing these subforms, but if I open them again, the data fields (combo boxes and text boxes) will have random data in them.

This is a easy one (i think) I am using MS access 2003 and. I am having problems continuing SQL statments to another line. I have been trying &_ and that doesnt seem to work with my SQL statements. How do I do this. I have some long SQL statments and it would be easier to break to another line, but I can't seem to do this. The statment below gives an error.
sqlz = "SELECT [Crosstab AUS].* INTO [AUS REQ] &_
FROM [Crosstab AUS]"
I have a 'For Each...' loop in the VB.NET code for one of the pages on my website. There is also a Try/Catch block within this code that currently contains an 'Exit Sub' in the event of an error being trapped. However, what I would actually like to do is to merely exit the current loop value and recommence the loop at the next value in the sequence.
How can I do this?

View 3 RepliesI am making a Tetris program and I have a 2d array 10 by 20 for the grid.I want the Tetris blocks I have created to move down one block every second unless the user presses "a" or "d" (to move left or right) then the block should move left or right whilst moving down.The problem is that I have created a loop for it to delay a bit but then it waits for the user to press a key until it continues the program. So the block will stop moving down and just stay where it is until they press something.I have been told that you can do this in C with something like if keyboardhit or kybd() or something then it will read the key but otherwise it will just skip that bit and loop round. So how can I do this in VB?

When you are putting in a long string of code it doesn't all fit, so I want to know if there is a way to continue that string on the next line. I believe it's something like & _ if I'm correct in thinking. But I'm not perfectly sure, I guess the question I'm asking is if you can continue a string with & _ or if it is something else.
