VS 2008 Loading SQL Objects?
Jan 5, 2012
I am creating a sports bet program and have set up a database in sql server 2008 R2 with results for games including wagers, odds etc. I now want to display this data in a range of listboxes, textboxes and labels in my VB.Net program.I am quite happy to play around and learn myself however I would love it if someone could get me started by completing one of the simpler labels. This label has to display the entry in Team One in labelTeamOne.
show me how to do this? I have already imported the dataset using the database wizard so all I need is the code.

i have a sql query that can bring back a large number of rows via a DataReader. Just now I query the DB transform the result set into a List(of ) and data bind the Grid to the List.This can result occasionally in a timeout due to the size of Dataset. I currently have a three teir setup where by the UI is acting on the List of objects in the business layer.

I have a window application develpoed in vs 2008, framework 3.5, in which i have put a button.. Now where i click that button the other text boxes are filled up with the data from database thru web service.. what i want is while all text boxes are being filled i want to show an animated loading gif image till data loading is completed in all the text boxes.. i have tried to use image picture box but while data is loading gif image is displyes but in static mode.. cant see animation... i think this is because data loading and animation both are done thru one UI thread..

long story short, I have created a ListView type control, using UserControls for the parent control and the ListViewItems. Most the of the control is written and works fine, right up to the point where I tried to replicate the 'Control.SelectedItems(0).Index' property and the 'SelectedIndexChanged' event.
Each child object knows its index value, and could pass this value via the SelectedIndexChanged event (assuming this is how it works in a normal ListView control -- user clicks on an item, and that item fires an event updating the selected index value in the parent object).
How does the child object raise an event in the parent object? I have a feeling this could be done with Delegates, but I'm still learning about their usage.

The plan is to use a database just a MDB one, which holds all text fields for all the objects in my application.For example (real dodgy example)Label1.text = "Select NewText from Table where [ID] =" & Label1.Name & " and [ENABLED]=1"..I want this to go for every single control in my application, which basically would allow any client to completely customize text fields in the app.Currently I'm using this so far to access the Data. But before I continue I want to see what you guys would do?[code]

I have a tab control and what I want to do is when I click on the tab, data is loaded into the DGV. This does not happen until I click on the tab page several times and then the data is shown. What I did was I took the dataset fill from the Form_load and put it in the Tabpage2_GotFocus procedure thus:

I'm trying to get my program to launch another .exe within the project folders. At the moment I am using:Dim oasicer As Process = System.Diagnostics.Process.Start("oasicer.exe", "hammer_8_8.txt")but the program starts and stops straight away. the files were originally in a folder called OASIC in the debug folder, so I had "OASIC" before them, but that didn't work either.

I'm making a log for my application.I have made the log and it works.I use the streamreader and the streamwriter to save and load the data. I thought that it would be more organized to have columns inside the log.The problem is how will i save the information to the text file and load it up again so that it could organize itself again. The code that i used to make the columns.
log.Columns.Add("Task performed ", CInt((log.Width - 4) * 0.3), HorizontalAlignment.Left)
log.Columns.Add("Time and date", CInt((log.Width - 4) * 0.2), HorizontalAlignment.Left)
log.Columns.Add(" Amount of detected files(s)", CInt((log.Width - 4) * 0.2), HorizontalAlignment.Left)
log.Columns.Add(" App version", CInt((log.Width - 4) * 0.4), HorizontalAlignment.Left)
The code that i use to add the information to the log.

I am trying to load an Excel 97 single tabbed spreadsheet into a SQL server table using the OleDbDataAdapter function. From all the documentation I have found, the first parameter should be "select * from [sheet1$]". This works fine for me only if the tab in the worksheet is named Sheet1. If I change what's in the [] brackets to the actual tab name, it also works fine.

I want to create a form that, when starting, will display in a ListBox the content of a txt file. I know the file is read because I can display the content in a MsgBox. Here's a snippet of what I tried so far:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim filein As String = "MyProjects.txt"
Dim objReader As New System.IO.StreamReader(filein)
ListBox1.Text = objReader.ReadToEnd
objReader.Close()
End Sub
When I debug my app, ListBox1 is empty.

I am loading an access database in vb.net using
me.adaptername.fill(me.datasetname.tablename)
The thing is that this takes a lot of time and the program doesn't move on to the next line until it finishes loading all the data. Some of these tables I need only later but I don't want to make stall work while doing it. Is there a way to load a database without waiting for it in the code. and a way to check if it finished loading in code. this way i'll be able to load it in the backgroud after the program has started and if the user wants to use options which require tables which weren't loaded yet i'll be able to know and avoid errors.
