I am looping through my dataset to save my database, I thought this might not be the best way. Is there a more resource efficient of doing it?

My problem is fairly simple. What my code is doing to start with is opening the form by loading a bunch of things from a database. After all the questions are done (because it is a questionnaire) it is meant to save the current score and the username that was entered before, for the sake of programming I have hard-coded a username and score however I think because I am using a different command builder it keeps giving me the same error!
(I am studying A-Level so that might explain the simplicity of the code)

I created a SQL database using the migration tool.I am converting my access forms to VB.net (VS2008).I am wondering if I create a single dataset in studio to the database or do I create a dataset for each form (query)? I am trying to determine what the best solution is. Many of my forms have drop downs that are populated using queries from tables.

I have a parent/child relation I am trying to create fow 2 datasets.The parent ds consusts of a range of PO Header information
After I fill this dataset I loop through it getting the PO number. I then take that value and execute another sql statement on the DETAIL file and fill a dataset(dtlDS) for EACH row in the parent. How do I add to this dtlDS for each row? I am getting no CHILD data in the merge. Should I be filling to a datatable and do an add.row and THEN dump into the dtlDS?

I have a model that returns a dataset to a view and builds a list. The crazy thing is that I have tested this code with IE, Safari on Mac and Windows, Chrome and Opera and all return data. However, on the iPad or iPhone, zero rows are returned from the dataset object. It seems that the model is in fact passing the dataset to the view. I am using jquerymobile to render the view for the iOS devices and have taken that out of the mix to test and it still doesn't work.

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 a piece of code that works for adding multiple rows to a dataset but I think that it is a lot of code and thought maybe someone may know a better way of doing it. I need to add rows to the dataset based on the selection of a combo box. ie if the user selects 15 the the program adds 15 rows to the dataset.

I am new to vb.net and I am trying to query a database and print out the records in the row to the console window. I got it to work, but I have a feeling that there is a more concise way to do this. One thing that I am sure is wrong is that I had to convert the dataset to a datatable to be able to retrieve the values. Is that correct? Could you take a look at the code below (especially the for loop) and let me know what I can improve upon?

My Application uses For...Next loops to read a spreadsheet into a DataSet and then display information from it based on the results of search conditions (search term and a date range).I'm having a problem with the data where, if I run a search that should return the first 400 rows in the spreadsheet, I'm only getting around 200 results. I know the search should return the 400 rows because I checked it in the spreadsheet before running the search.I think my problem might be caused by my date comparisons. I think the problem might be that I'm comparing String valueHere's my code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If ListBox1.Items.Count <> 0 Then : ListBox1.Items.Clear() : End If

I have a form with the datagridweiw object. I have connected it to the datasource and it displays the data fine. I also have set the persissions for editing. I am assuming i need a button for accepting changes to table and a button to cancel. My use for the form is to add or delete rows of data and save the changes. The database and application are both in visual basic and sql server express both 2008.

I have used VB6 for all kinds of database programming. Now I am fairly new to the vb.net. How do we read the records (rows) from a dataset and manipulate data? I want to populate a combobox or a datagrid with a recordset (in VB6 language). What is the .net equivalent of ado dataset, and how do I use it. I have tried several ways using dataadapters and dataset, etc.

I am trying to retrieve row data from a table in a dataset (dataset name is PatientsDataSet and table name is tblfacilitiesnames).
I am using VB 2008 but the code I entered is from a VB2005 sample so something must have changed in the format.
I am already connected to the database since it opens the connection when the program is run.
Here is the code:
Dim Counter As Integer
Dim Str1 As String
Dim FacRow As PatientsDataSet.tblFacilitiesNamesRow

I have a question similar to this one, but reading the (accepted) answer didn't give me much insight, so I'm hoping to state it more clearly and get a clearer response back.
I'm attempting to insert a data row into a table. I'm using TableAdapter's custom "insert nonQuery" that I wrote (it works, I tested) to accept some parameters. I'm fairly new to this business of communication with a database via .NET and what I'm doing is probably wrong by design. My questions are why is it wrong and what's the right way to do it? Both are equally important, IMO.[code]...

I have a program that I designed that scans my music folder, gets the id3 information, and then in turn inserts the results into a dataset
Here is what I have:
MusicLibrary.sdf with a table called MusicLib
MusicLibraryDataSet
MusicLibBindingSource
MusicLibTableAdapter
DataGridView
So far here is where I am, if I open the database through the visual studio ide, I manually put in a few songs just for testing purposes. When I run the program the DataGridView displays the data I entered. However I can't seem to figure out how to actually programatically add songs to the database. This is what i did so far:
I execute this command for each song scanned:MusicLibraryDataSet.MusicLib.AddMusicLibRow("FileName", "Artist", "Album", "Title", "Track") Then when done execute this command:MusicLibraryDataSet.MusicLib.AcceptChanges()
After I do that how do I then insert these items into the sql database itself so that the next time I load up my program the info is there. I have plenty of sql experience, but am used to doing all this in asp.net, i've never quite gotten all the table adapters and stuff.
