Visual Basic Saving To A Database/Dataset
Mar 1, 2012My 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)

Jun 21, 2010I 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

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.

View 17 RepliesDB/Reporting :: Saving Dataset To Sql Compact Db?
Feb 18, 2008I 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.

Reading Data From API Feed And Saving Into Files
Mar 17, 2011I am reading data from an API feed and saving the chunks into files. When the files reach 10 MB I start a new file and write to that file. What happens now is that an entry (<entry></entry>) can get cut off at the end of a file and continues into the new file. I try and reconstruct the files by taking the last entry and combining it with the first entry of the next file but this is tedious and was wondering for better suggestion on handling the data transmission and file creation.
The data stream is of variable sizes and where one request can return 60 MB of data the next can be as little as 2MB. I know the data stream will end with a token </feed>but my problem is the cut off data in between. I guess I could just make the max size really large and then hope the data is never more than that but then I have to work with large text files and reading in and parsing would be a problem.
timestamp = DateTime.Now
numbytesread = responseStream.Read(bufferread, 0, BUFFER_SIZE)
If numbytesread > 123 Then
'timestamp = DateTime.Now
responseData = Encoding.UTF8.GetString

Readfile()

Dim strLine As String

Reading Dates In Spreadsheet To And From DataSet
Jul 22, 2010My application uses a badly arranged Excel spreadsheet as a data source. I say badly designed because there's no unique identifier to each row aside from the column where dates and times are found. My app uses the date and time on each row as an identifier to retrieve information from the other columns in the row. The idea is that the user will select a date/time from a ListBox at which time, the app will loop through the DataSet and find the date/time in the right column and display the rest of the info in that row. My issue is that the ListBox control isn't being populated and I can't see why...
Here's a sample row from the spreadsheet: (Each | character represents a cell border)
Team - FNB | O | 2010/02/18 08:59:24 | 5034 | Frederico Turnbridge | 27839963586 | SA - MOBILE - (ZA) | | 69 | O_NORMAL | | 00:01:06 |R 2.83
Here's my code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim j As Integer = 0
If TextBox1.Text.Length = 4 Then
For i As Integer = 0 To CallData.Tables(0).Rows.Count - 1
[Code] .....
This basically works on a search where the user will specify a term to search for (be it a telephone number or (in this case) a telephone extension) and a date range. Now, I know for a fact that the spreadsheet (and thus, the DataSet) has information where the date column - column index 2 - falls within the date range I'm specifying and the column after that contains my search term, but I'm not getting any results.
VS 2008 - Reading Value Returned From DataSet
Oct 8, 2009I have a dataset which creates a table adapter to the table I need. I call a query on that table adapter which returns the number of fields returned. In this case it's one field and will always be one field.. I am filling a variable with that query.. however instead of the fields returned I need the actual data.
This is how my current code sits...
vb.net
Dim aUserName As String
'TODO: This line of code loads data into the 'DataSet1.IT_Staff' table. You can move, or remove it, as needed.
aUserName = Me.IT_StaffTableAdapter.FillByUsername(Me.DataSet1.IT_Staff, SystemInformation.UserName)
Do I have to load this into a variable declared as a datatable then somehow call the column and row 0's value? If so how?
