Ok here we go again, im a complete beginner to coding and have started with visual studio 2008 using the .net/vb libraries, as my first project i went with an emulation application, and it went great:So now i think its time to move onto a little more advanced tech's, so i added in a combo box and i want to change how my code works, and this is where my troubles are.To start of with the combo box, i have it added to my winform and have 3 items on it 'Action' 'RPG' and 'Sim' and i have made 3 .txt files in the projects root folder with the same names. What i want to have happen is when the user selects for instance 'RPG' from the combo box the items displayed in the listbox change to the contents of the rpg.txt file. After searching around for a few hours and no luck i tried this
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
If (ComboBox1.SelectedItem = "RPG") Then

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 have a Customer File, and want to serach through the customer file to find a customer. I want to be able to Load the data into an array, and then from that array into the list view. BUT i don't want all of the feilds. I only want 3 (out of a total of 7), CUST ID, FNAME, Lname, etc. When the user clicks on the searched Customer, it then displays that customer in the form.
What I am not sure about doing is loading the file into an array
Edit: The file is a .dat file. I will happily attached my form if someone requires it
EDIT2: Can't count to 7

Im trying to load a price of an item from a prices file (Items). The variable (ItemName) is taken from a listox populated from the file on another form. And (Item) is the structure which i saved the prices information for into (Items).
What im trying to do is take the string from the listbox and change the textbox (txtCurrentPrice) text into the price for the highlighted item, which is also the name of the (txtItem) textbox.
However i cant find a way to reference the Item.(ItemName) to get the correct price from within the file, as ItemName isnt a member of the Items structure Item instance.
ChangeItemForm
Private Sub ChangeItemForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
ItemName holds the name of one of the variables saved in the structure. So say if ItemName was holding "IridescentRoll" As its string I would be trying to find Item.IridescentRoll, which would show me the price of IridescentRoll which im trying to put into the textbox. and As Item.IridescentRoll = 3.35 it would display 3.35 in the textbox.
As you have probably guessed, the Item.ItemName doesnt work ('ItemName is not a member of...'
Is there any way to write this without having to create a new record for each item? As that would take a while, and im not sure i have the time x.X

visual basic 2008
I am pretty good with visual basic and visual studio, but the one problem I have is saving... I am currently creating a game, and it has a lot of variables, I want o be able to save all those variables to a text file and then re-open it later. When it is open, i want the variables to have the original value from the text document.
To sum it up: I need variables to be saved in a text file, and then be able to open the text file back and have the variables have the proper values from the text file.
I have been searching around google, and I found ideas, but I have no idea how to use them. Like using XML or saving a table with " TextFile.WriteFromTable" "TextFile.ReadToTable" but I don't exactly get how to use those (the posts weren't too clear)

I want to do a project in vb.net 2008 using database from MS Access 2007. I have to go from the main menu to the other forms, in each form I have to select one or more items, each item has a price (should be taken from the database *.accdb), then I have to return to the main menu, click the cost button to find the total cost of these items.
1. Where I have to write the code to access my database, in the main menu or in each form individually? and how to write it? I used the code found at:
http:[url]......
but after DEBUGging told me that it cannot see "Table1"?
2. When I am in one of the forms, do I have to "save" my selections, and how?
3. How do I exit from any of the forms to give me the total price to the step, form, I have reached?
4. The total cost should appear in a separate form (screen) at the same time should be saved?

I am trying to use if statements to add the prices of a cruises special packages together. I am using check boxes for the packages, so any, from none to all 3 are able to be checked. The packages available are VIP, excursion and restaurant. The price will also depend on the cruise length (7 or 10 day). I am wondering on which format to use, and if I even need to use if statements, how to make this statement true,

I am trying to put together a simple form with prices assigned to Radio buttons and check boxes.
I started by creating a simple form with four Windows Form control, two check boxes and two radio buttons, there is also a NumberUpDown Control for quantity but I have not added that yet.
Basically the user make selections, the price is calculated with total and subtotal and displayed on a label.
I am trying to start as basic as possible then work my way up to more complex calculations as I progress.
Here is my Screw up version: :)
