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'm trying to load the contents of text files into a listbox. It loads the file fine but adds an extra character at the end. I have a feeling it has something to do with my Split command but I'm not sure how to fix it.
Here is what I have:
Dim ofd As New OpenFileDialog
ofd.Filter = "Text files (*.txt)|*.txt"
Dim result As DialogResult = ofd.ShowDialog
[Code]....
So i have a text file that is created in the program which can be loaded back into the program(game save)
Whatever is in the text file "stats" should be listed in listbox1 in the same order it is in the text file. The same with "items" in listbox2. And then "quests" will be in listbox3.
The problem is when i load it instead of what is in the text file it says...
note that box3 is correct that it has nothing in it.

I need to load the contents of a text file (itemInfo.txt) into a list box

The duplicates need to stay as they are in the text file. I just want the duplicates deleted from the listbox when viewed. How would I do that? Say there are two orders made by the same user. I only want the user to show up once in the listbox...
View 3 RepliesI was wondering if you guys could help me. I have a web browser made, and now i'm working on coding my favourites system. It is working well, and adds the URL to My.Settings.FavList
My problem is once you've added a favourite then load up the favourites form, it appears. But if you don't add anything, and load up the form, nothing appears. Below I have attached my coding, I hope you guys will be able to help. Also i'm still learning VB, and almost all of this coding was done through me learning myself. So yeah, there may be parts wrong. Form1 - This code is to add the favourite. I don't think anything is wrong with this part.

I know it has something to do with the Favourites_Load, i'm just not sure what to put in. I have literally tried everything. The thing is, I bet it's something simple, and this is a noobie question.

View 5 RepliesIm 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.

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

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 have created a project with a search form. add new record form and a also have an edit record form.Under the add new record form I have added an attachment button an a opendialog where I can select multiple files, so far this is working great, then I add the name of each file that I select and added to a listbox, so far so good,for example:
View 4 RepliesWhen my form is loading, it executes a Method called populateListBox().As the ListBox is populated, it inevitably triggers ListBox.SelectedIndexChanged, which triggers this

If I stick the Try...Catch in, allowing it to bypass the error, everything loads fine and when I double click an item in the ListBox, I have a MessageBox setup to show the SelectedValue, and it works fine (it shows a number like it should). Even if I put a MessageBox in the SelectedIndexChanged event, I still get the same error on the MessageBox line during the loading of the form.
Is this because the form is not fully loaded that I get this error? And what would be the proper way to handle this? I need this code in the SelectedIndexChanged for when the user selects a new item, so how do I keep this error from happening (or maybe even the event from triggering) during form load? Because I'm sure having a Try...Catch is not really an accepted form of "fixing" an exception; it's just ignoring it.
why my code doesn't work? I want the array elements to be loaded into a listbox when the button is clicked. Is it because not all elements in my array have been filled? I've tried putting the array declaration as a global variable and as a local one (below), but the same error occurs as soon as the button is clicked - "ArgumentNullException was unhandled".

I'm loading custom listboxitems in to a listbox.But the problem is that i load over 300 items and it takes a while and the program stops responding.I've tried to load the items in a backgroundworker, but i didn't help.
Note: the Listbox is placed on a Page.
I want to make a program similar to this one: [URL]. I already have the ListBox ready. But how do I load the images?
The image name works like this:
-File1.package
-File1A.jpg
-File1B.jpg
So the .package is removed and A.jpg or B.jpg is added.
