Saving Data To TableAdapter?
Nov 17, 2009
I have code that saves changes to data on a form and it works fine. I then used the same code on a different form (only changing the name of the bindingsource and tableadapter), but changes I make to the data don't save. Why will it work on one form, yet not on another? Here is the code I am using to save the data on the form that works:
Dim deletedRecords As DataDataSet.CatalogDataTable = CType(DataDataSet.Catalog.GetChanges(Data.DataRowState.Deleted), DataDataSet.CatalogDataTable)
Dim newRecords As DataDataSet.CatalogDataTable = CType(DataDataSet.Catalog.GetChanges(Data.DataRowState.Added),
[code]....
The only difference I see is that on the second form (the one that won't save) I have other tableadapters loaded. But they are just used to load data into different comboboxes. What could be causing the second form not to update the tableadapter? I'm not talking about running the application, making a change, then closing the application and it not saving. I realize that a second database is created because I've set the Copy to Output Directory property to Copy if Newer. I can tell it doesn't save because I run the application, open the form, make a change, close the form, then open the form again. The change I just made is gone.

I've been struggling the entire day trying to figure this out. Basically the data in my form won't save to the tableAdapter. To update the database I use:
Me.dataSetName.TableName.Rows.Add (DataRowName)
Me.tableAdapterName.Update(Me.dataSetName.TableName)
The database was created using SSMS 2008 R2 and I'm using VS 2010.
I have confirmed that the data is being stored in the data row (because when I removed data from the data row it wouldn't accept because there are NOT NULL columns) and I have followed the instructions of this form as well:[URl]..

I am trying to fill a temporary table with one column( a code) with the unique results of three queries of their respective table adapters.I can't figure out how to do it from here.The database is Access 2007 and I have activated the appropriate dataset on the form from which this code executes. The table adapters are part of that dataset.I could try to use the recordset approach, but that means making another connection to the same database.Is that a preferable approach?My purpose in doing this is to build a VB process like the one that works in a VBA Module of this Accessdatabase, partly to help me learn VB2008 and partly to overcome the necessity to keep updating queries used by the module.Code below

I'm an experienced Office & VBA programmer, I am new to .NET programming. I'm in the process of migrating an Access 2007 database application from Access to Visual Studio Visual Basic project for further development. In particular, I am interested in using .NET controls to display data in a user-friendly hierarchical grid control.The data for each hierarchical display is stored in two separate tables (I call them tblData and tblExtraInfo), and then I use a query to join the data and prepare for display (I call the query qryBOM).

I was working through Beth Massi's article, "Using TableAdapters to Insert Related Data into an MS Access Database" here: http:blogs.msdn.co...s-database.aspx
And I configured the TableAdapter exactly as shown by Beth, yet I am getting an error here:
Me.OrderDetailsTableAdapter.Update(newOrderDetailsRow) The Error says: "You must enter a value in the 'OrderDetails.CustomerID' field."
I am using this code for inserting a related record:
Namespace MyDataSetTableAdapters
Public Class AccessIDHelper
'<summary>
[Code].....
I am not able to insert and move on as I am getting the error marked above.
What could be possibly wrong with the above code and why is this giving an error ?

I need to control a device with a GPIB port. I have the commands that I need to use to do this; but I don't know which is the sintaxis in Visual Basic.
For example if I need to send a instruction like "START:0.01" to the external device which are the libraries that I have to include?, how should I write the programming line to do this?
The main tasks that I need to program are sending data, receiving data, and saving data

I am using the TableAdapter Configuration Wizard and under Advanced option I click on "Refresh the data table" and carry through to the end of the wizard. However when I run my code and want to update the dataset on the form I get the error message "Update requires a valid Update Command when passed with DataRow collection with modified rows". So, ok, when I look back at the Dataset with right click and configure I find that that the "Refresh the data table" under Advanced Options is no longer ticked, even though I had ticked it before and finished the wizard. Somewhere along the line the tableAdapter is losing this value.

What I am trying tot achieve is the following:User inputs data in one form that saves to the dataset table no problems. On an edit screen I want the current data saved to appear in this page within all the relevant fields but when saving I want this data to add to the dataset table as an additional line of data so the transaction records are kept.I want to add a new datarow regardless of it saving one change or all 7 changes that are possble.
e.g. Line 1 - user inputs 7 cells of data Line 2 - user amends 2 cells of data Line 3 - user amends 1 cell of data an so on. Unfortunately the terminology for certain items above may not be correct as I am still new to this programming and still on a massive learning curve.At the moment I do not have the code for what I am trying to achieve as I really dont know where to start with it.I am currently able to save the data and have it appear in the "edit" panel however only the cells changed are saved an it overwirtes the initial input.

I'm trying to create a simple Data Grid that will automatically save changes. So far I have a data grid connected to a MS Access 2007 Database that reads the data. I can create new fields in the Data Grid, but I need to program to save the data automatically to the database on update (or on close).

I'm working on a project which are generating some data from my VB.NET software and I wish to save those data into sql server. But my concerns is the speed of saving and the large amount of data. For every 0.5s, one set of data will be generated and the process will keep running for about 8 hours, so at the end of 8 hours, roughly there will be 60,000 set of data generated.May i know what is the best option/method of saving the data into the sql server in not hanging up my software and also keeping the pace with the speed of 0.5s data being generated?
- Speed of 0.5s. I have to maintained for every 0.5s, one data must be generated. Cannot delay too much.
- I can afford delay in the sql database, meant the data might not be necessary close to real time.

I have a small application that consist of five tables. The main table is called inventory. I have four tables linked to the Inventory table
[code...]
I can go in and enter data, create a new record and add more data and then click Save - nothing happens. I can cycle through the records and they will show. However when I exit and reenter the program (stop/start debugging) done of my new data is displayed.
I am thinking the problem has to be with the four tables connected to the main table via the ID's. Although a record is not being added to these subtables. So, I am not sure what's going on.
I have provided the code below. Please take a look and give me some direction.

I have a very simple DataSet linked to a ListBox. I need the User to be able to add Data and have used the following code (in a ToolStrip command button):
Dim newFileRow As DataRow = Database1DataSet.Tables("tbl_Files").NewRow()
newFileRow("File Name") = fleName
newFileRow("File Path") = flePath
[Code]....
This seems to work ok - the new Data immediately appears in the ListBox. However, as soon as I close the form all of the Data in the DataSet is lost.

I have created a form, that calculates Hotels billing, with one box I can input Number of nights a customer stayed which is £32.50 a night per room and the other box £4.50 for breakfast, there is a deposit of £25.00 which gets deducted upon departure. I have created this form with success along with a clear button But here is the tricky part- I want to create a total button which will display a summary information about the bills paid on that day regardless of how long they have stayed and how many breakfasts consumed. this should include, the total number of bills paid, the total number of nights paid for, the number of breakfasts paid for, the total amount of all the bills added together including the deposit.

What I have is a program that is going to monitor and store different stats about different email servers. The basic layout of the main form is a datagridview. Now this program does not need to store the information into a database as it is only going to run on one machine which is why I did not bind the datagridview to a dataset. Maybe using a datagridview is not the way I need to go but researching around the only other option would be to save the data to XML. However since the table does contain hidden fields with authentication credentials, I am a little bit hesitant about doing so.

Actually I meant for inserting the data entered in the text box, but now saving is the code itself i,e; in port_number column 'CIng(txtPort.Text) ' will be saved

I'm using VS2008 with SQL Express 2010. I've a one to many relationship and a form with these two tables on. I'm using the BindingNavigator toolbar and when I press the + button, a new record appears. However, I have to press the save button and save the parent data (which is in Details view) before I can add any data to the child table (which is in a DataGridView). Once I've clicked save, then I can add child data no problem, then I click save again and all my data is saved.
Is there any way to save all the data at once? If not what is the best practice for telling the user when to save? Should I make the child data grids invisible until the user clicks save?
