I am wanting to create a menu based on items in my MS SQL database i have 3 tables
FormTbl
FormID - Int Eg (1)
FormName - nvarchar(50) Eg (Form1)

I can get the form names to be populated in to the menu and can open it my question is how do i set where the menu items will be placed. Eg File with FormHierarch 0 will be the very first one. Exit with FormHierarch 0.1 will be the very first one under File

i have a custom SiteMapProvider which I populate from a database. I also have a custom SiteMapNode which has to be constructed with a custom Page argument.[code]Should I return false in AuthorizeCore() to have everything work according to default authorization protocols? (What are these?) Or should I throw my exception.SiteMap.CurrentNode is Null / Nothing (in AuthorizeCore()) if the page which is requested is not accessible to the user (obviously). How should I change my implementation? I want to keep the functionality that the Page objects are only loaded once, so I need to store them somewhere.

I'm thinking about using the treeview for creating a phonelist. The issue here is that I can't think how to load the data into the nodes according the group they are categorized in.
Here's a screenshot of my test_database:
So there is an ID and a row with groups (groep). What I want is that when loading the data a DISTINCT node gets create for each group and that the person is added to the sub-node. Got the faintest idea where to start.

I've got a database that's 13,000 lines long and I'm trying to load this into a string array when the program loads but it takes approx 5-6 minutes for it to load it.I've got a MS Access database or an Excel file that I can load this information from, each has two rows: SVONo, Description This is my current MS Access
[code]...
Does anyone have any idea of how to make it faster? Or does anyone have a better way?I did have the idea of loading it by letting the user select the first letter and then only loading the ones that begin with that letter but I've got 4000-5000 'S' ones and it still takes about 2-3 minutes to load it All I want is to load the data from the database or the excel file and then put the products into 'cboProducts' and the 'cboProducts AutoCompleSourceList' and the descriptions into the 'txtDescriptions' AutoCompleteSourceList and a string array.Then when the user selects a product using 'cboProducts' the description will automatically be put into 'txtDescription'.

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.

I have a strange problem with creating an instance of a form which I want to use as a custom message box.
The idea is that when the user clicks the button to perform a database search, an instance of this form is loaded. The background image of the form never displays but the text on the form does - but it all works fine when I remove the call to the database.
I also tried putting a "proper" VB message box just before the database call and when I block it this way it seems to allow the image to draw on the form.I also tried using a timer delay before the database call - just a couple of seconds to see if that would allow it time to draw the image.

PictureBox1.Image = Image.FromStream(ms)
It gives error on DsPic.tblPicTest.Item("Picture")) portion of the statement.
I also tried
CByte(DsPic.tblPicTest.Item("Picture")))

I am doing a small MS Access database based program, but I got one problem. Instead of loading the the rows like this (each nr is the count of the row):
"1,2,3,4,5,6,7,8,9,10", it loads it like this: 7,8,9,10,1,2,3,4,5,6
Here is my code for where it loads the data:
con.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source =" & Application.StartupPath & "\Filmer.mdb"
con.Open()
sql = "SELECT*FROM Film"

I'm having a problem with loading my MS Access Database. I can get it to load but it won't load in a row. My friend told me to try this but it puts all the information in a column instead of putting all the information spread out accross the row.
Here's my code:
Dim lb_Connection As New OleDb.OleDbConnection
lb_Connection.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA SOURCE = pass_database.mdb"
Dim lb_SelectCommand As New OleDb.OleDbCommand

Also I'll attach an image of what the program does when I load it.

I'm writing a program in VB.Net and loading the info into a SQL database. Debugging it works fine on my machine that I am programming it on, it connects to the database and runs through all the info perfectly. However trying to get it to run on another machine it will not connect to the database. I realize the reason for this is the connection string, it's looking specifically at the file directory for the database. How do I change this so that it will function on any machine. The program is only intended to run on one machine at a time and not over the internet.

I was writing a program that would save the contents of a listbox to a database and wanted to reload the users' choices when the opened up that particular row again. My first thought was to do it with two for loops, just as I used to do in VB6, but I thought there must be a better way to do it. And there was. Sort of. It basically involves using the SelectedObjectCollection class.For this demo, you'll need a listbox called Listbox1. Set selection mode to something other than "One" or else it won't work as expected
Dim items(0 To 3) As String
items(0) = "One"
items(1) = "Two"
