I'm trying to progress my programming abilities by coding in Visual Basic forms. I've created a database and linked that to a VB form, I'm now coding a way to write into the database instead of reading.I'm filling an array which is in-turn put into the dataset row by row however when attempting to 'update' the table adapter I get the following error:
View 1 RepliesHonestly I do not understand why I need to write code to update a databse and why it stores it localy. I'd simply rather the system update the individual row after it is scrolled off of.
In either case since I guess I can't do that.
Here is some code in a button on a form
Try
ItemsTableAdapter.Update(NewCreationsDataSet1.Items)
LineCodeTableAdapter.Update(NewCreationsDataSet1.LineCode)

I'm using VS 2010 SP1 and Oracle 11g with Oracle tools for VS 2010. Previously I had tableadapters that queried the db with a where clause on a number column or date column as described below[code]...

I'm using Queries within the TableAdapter to grab certain data record field validations, most of them are using the Scalar Query to see if a certain condition returns a record or not.
I have one check I need to do that SUMs three fields and have tried it with both a Scalar and Regular Select, both return the results fine, my problem is creating the right syntax in the VB code to check the returned values.
Here's the Query Code in the Adapter (called GetInvoiceSum) and I pass it the cJobNum
SELECT sum(taxable) as taxable, sum(material+labor) AS subtotal, sum(tax) AS tax from ticket where jobnum = @cJobnum Here is the Code in the VB app - it gives me errors on the declaration and I've tried various types DataRow, DataSet, etc....not sure what I'm missing here and am very new at this....
Dim nSumTicket As DataSet = Me.TicketTableAdapter.GetInvoiceSum(cJobnum)
I have the following query that executes when my form loads. It's the rowsource for my combo box. The query is fine and populates the combo perfect, however, when i click into the combo box I cannot click out of it or even close the form. I have tried taking out the line of code that fills the form via table adapter on load and it works fine (opening the form unbound by the main table). Has anyone run into this before? I have another combo box on the form setup the exact same way and this is not happening. I've experimented with different datatypes etc....
code to populate combo box:
Public Shared Function LoadCallSource() As String
Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Documents and Settingsdiw07My DocumentsDaily Backupsphone memo backend.mdb"
[code]....
If I take out the line
Me.MemoTableAdapter.Fill(Me.Table_Memo.Tables("Memo"), intMemoID)
The Combo boxes do not act up or "Lock"
I have a data table whose one column is related to a column of another table. I have a listbox in a form which shows a column (which is sorted by another column value by ORDER clause) of the parent table and other columns are in textboxes. The child table is represented by a datagrid. When I add a new item in parent table and click save, the newly created item is listed at the bottom of the listbox violating my ORDER clause. When I wrote some codes to fill data again after updating, it shows an error message[code]...

on a windows form i have a combobox called currency, it is populated by a table-adapter called exchan-gerate which is turn populated by a dataset called mydataset. on form load, i issue update commands to the back-end database that holds the table which populates the dataset - they work. if i look at the update to the combobox, they are not reflected until i exit and restart the app - then they're fine. further down the form load i've tried:
Me.exchangerate.Update(Me.DataSet.Currency)
Me.CurrencyComboBox.Refresh()
am i missing something silly to have the values in the combobox change and refresh at the time of the update to the database? as i said, an exit and restart of the app displays the accurate data.
I 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.
How do you restore a dataset to the previous state before updating the database with a data adapter? I have a concurrency update problem that I believe to be caused by this. The update fails during the update and a rollback command is issued using a SQLTransaction object. However, now the rowstates of the rows that did not have errors have been changed to unchanged. So this record is no longer availible to be inserted into the database. When I updated the value that could not be null and then test the second update which runs just as the first does then I get a concurrency error. The update code is below:

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?
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. It has got queries done via data sets and table adapters. dsStagMyfileDesigner.vb and dsStagMyfile.xsd are the files having all the sql queries.

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 5 RepliesI have the following problem, I am looking to display information in a textbox that takes information from a table adapter and displays it in a text box, the code below shows the data being displayed via a table adapter
[Code]...
I 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 can do this easily with table adapter, but I can't seem to use variables in the table adapters connection string, or specify the connection string to use before "filling". Is there a way to populate the form without using any sort of binding? Currently I've used this method - a search form that populates a list box, and on the double click action I have this:
Private Sub lstResults_CellMouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles lstResults.CellMouseDoubleClick
'Fills Main Form
Dim firstcellvalue As String = lstResults.Rows(e.RowIndex).Cells(0).Value.ToString()
frm_IMT.intPendingID = CInt(lstResults.Rows(e.RowIndex).Cells(0).Value.ToString())
frm_IMT.Show()
Then When the form loads:
Me.PendingTableAdapter.Fill(Me.Phone_memo_backendDataSet.Tables("Pending"), intPendingID)
