View 3 RepliesI have a form that has a datagridview and a table adapter that displays data from a SQL database. What I'd like to do is that when edits are made to the data in the datagrid, I'd like to post all of the data back to the table. I know that you can do that with a dataset and a data adapter, but I don't know how to do that with a table adapter. Here is the code for my page:
Public Class ExceptionEdit
Private Sub ExceptionEdit_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'MDRDataSet.scratchpad3' table. You can move, or remove it, as needed.
[code]....
When people click on the Save Exception button, I'd like to save back to the update the database with the new data.
I have a form with comboboxes, if the user doesnt select a value in the box I want a null to be sent to the database. The insert works fine, i look at the record in the db and see the null. The update doesnt work. gives me a n "Update statement conflicted with foreign key constaint....."
Public Sub Update()
TableAdapterCreate().Update(ID1, ID2, CType(cbox1.SelectedValue, Integer), CType(cbox2.SelectedValue, Integer), CType(cbox3.SelectedValue, Integer), CType(cbox4.SelectedValue, Integer),
[CODE]...
As I step through the selected value of the cbox 5 is shown as nothing (which it should be because the user didnt select a value for this combobox). I assume this needs to be a null instead of nothing to get written to the database. the combox boxes need to match a primary key in another table so sending a 0 would also result in the forieign key error since the related table does not have a 0 ID field.
As the title says, when I attempt to update a row in a table in a database, I recieve an InvalidCastException. I am unsure why, since the variables I am using should be, and indeed, when I check them at runtime, are filled with the correct data.
I am trying to update using the method wherein the row that is being updated is identified with all the variables already stored. Interestingly, Intellisense is telling me that EntryID, the primary key, is only necessary in it's original form, and that the variables that I am attempting to update have question marks after their type.
when trying to use the update command for my table adapter, i get the following error.

i've used the same commands several times and even tried copying the code from another project and importing that table and still get the same error. am i missing a namespace or class or something?
I have a table with a multiple columns (two) primary key. I get an error on tableadapter.Update .How can I resolve that??
View 3 RepliesI have a windows form program that pulls data from a sql server. That same data is being read from a ASP.NET website that sets properties for the site. The SQL server has 3 tables: tblWebPage, tblObjects, tblProperties. and 6 views for the 6 web page: vWebPage01, vWebPage02, vWebPage03..ect. When the program loads you see buttons for each web page on the site. When the user clicks on the Home Page it loads this data: [code]Now, the problem lies in updating vWebPage02, vWebPage03, ect.. I assume with the same data I can copy my form with the code and change the form name and the data set to build and update. So that's just what I did changed the form name where needed and changed "vWebPage01" to "vWebPage02".When I tested the program My "vWebPage01" form it built and updated no problem. when I went to test "vWebPage02" it built the dataset and table adapter fine but it did not update at all.

View 1 RepliesI have a form that fills a table adapter with this:
Me.Scratchpad3TableAdapter.Fill(Me.MDRDataSet.scra tchpad3
and what I'd like to do is when users edit something on this form that they post the changes to a table called exceptionsedit which is not part of that dataset. What I don't know how to do is to how to insert those edits to the exceptionsedit table.
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?

I have code in vb.net that was created using Visual Studio 2008.

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 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.

i'm using vb 2008 and local database sql server compact 3.5 to build a application.the problem is that i can't insert a new data to the database from the app. i'm wrote the query right at dataset and using table adapter. but when i call the query, it succeed but the data don't exist at database.why when i add data, it's not working. actually when i run it, it says that adding process is success, no error, and it shows at the datagrid. but when i look at database. the data that i add is not there.and in tableadapter, i also make sortData, seachData query, i can use both of them perfectly when i run the app.so, i really confuse why is the insert query didn't work.
View 2 RepliesHow 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.

View 4 RepliesI'm having a hard time wrapping my head around data access in VB2010. I have properly set up a datagridview, table adapter etc... I have only 3 columns showing (out of 7 that are stored) in my datagridview (dgv for the sake of less typing).i don't show the ID column which is the unique index. It's hidden.what I want to do is have a button on each row (already done that) that, when clicked, deletes the row from the dgv AND the database. I have been able to get it to remove the row from the DGV, but not the underlying database. My background is in VB6 so i'm sort of flailing around in the dark here. I tried using [code]

I then have a number of table adapters for connecting my business logic to the database , One of the queries inparticular is a pretty large one and requires extra time to complete however the connection is getting a timeout error. When I checked the adapter connection with Dim connection2 As Int32 = Adapter1.Connection.ConnectionTimeout This shows the connection time out to be 120 seconds but the timeout is still occuring after 30 seconds.
This is what my error list and the correspond lines shows( all of these are showing in the designer code), I tried 3 days to solve it, well after tried lots ways still wrong, I came here.
