I am trying to be able to add everything within a listbox to a program setting that can be re loaded when its opened up again, I have the part to load them upon opening, but I don't know how to make it add all the items within the listbox to the setting, so it has something to load.
This is to load them on startup:
For Each item As String In My.Settings.logs
log.Items.Add(item.ToString)
Next
ok, I have a "sum" for ading the total prices in list view. The prices are in the sub items. After they are added up ( they display as total: �{0}) how would I save them to add up later amongs other things I have saved in my.settings???

View 4 RepliesAm using this INI Reader from CodeProject. I have a listbox with some items in it. I wanted to save the items in listbox to my ini file. I used the following code but the problem is, it only saves the final item.

INI.Load(Application.StartupPath & "Config.ini", True)
For i As Integer = 0 To List.Items.Count - 1
ini.GetSection("Initiate").AddKey("Part1").Value = List.Items.Item(i)

I am currently working on some tools and I am having some troubles adding new lines in a listbox.
vb.net
For i = 0 To lstFiles.Items.Count - 1
Process.Start("C:UT2004Systemucc.exe", "compress " & lstFiles.Items.Item(i))
If IO.File.Exists(lstFiles.Items.Item(i) & ".uz2") Then

The meaning of this code is that if the file exists, it will add a new line called Success below the dragged fileline. If the file doesn't exist it will create a new line called Fail below the dragged fileline.

View 2 RepliesI have a small program that talks to a server, grabs the content from a website using a php webscraping program and then places the results in a listbox as a string. My problem is taking this string and creating a list from it. Each item in the string is followed by a | (pipe). I have included the code that I've tried below:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim str As String
Dim start As Integer = 1

i'm creating a web form and i want a user to be able to make certain selections and then add the selections to a text box or listbox.Basically i want them to be able to type someone name in a text box ... check some check boxes and for it up date either a text for or a list box with the result on button click...
e.g.
John Smith Check1 Check3 Check5
I have this code to add Items to a Listbox:
Private Structure Bets
Public id As Long
Public name As String
Public size As Double
[code]....
I googled to find how I can change the items forecolor or backcolor. I want the items containing "Unmatched" to be one color and "Matched" another.
We have a button, textbox and a folder browser... We made it so that when you click the button it shows the folder browser dialog.. And you choose your folder/path, then it shows the selected path in textbox.. We are succesful on this.. But now weve added a listbox, And when you selected the path it will do this..
[Code]...
So I'm using the following code to add items into my list box, and I'm trying to get it to check the contents of the list box as well.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
If ListBox2.Items.Contains(TextBox3.Text) Then
MsgBox("Character already exists!")
Else
ListBox2.Items.Add(New LBnfo With {.v4 = RadioButton6.Checked,
[Code] .....
But when I try to compare the two:
If ListBox2.Items.Contains(TextBox3.Text) Then
MsgBox("Character already exists!")
Else
It doesn't show the message box even when the character actually does exist. I believe the problem is that I never do add the item really. I just use, "Return Me.character," which is assigned the value of Textbox3. So I just need to figure out how to check Me.character before returning it.
I want to manually add two items as "Active" and "Inactive" in a ListBox. When the user selects "Active", I want to get the value "A" and when "Inactive" is selected, I want to get "I". How do I do this in VB.NET.
View 3 RepliesHow would one go about checking a listbox's items for duplicates? Basically I need to write a program that displays the teams from a text file provided by my instructor, in alphabetical order. I can do that, but what I can't figure out is how to prevent the For loop from adding a duplicate team. What I'm envisioning is:
If teams(i).name is not in lstTeams.Items Then
lstTeams.Items.Add(teams(i).name)
End If
I have a program that compiles and works so far, except for the above problem and my alphabetical order (which I can probably figure out on my own:
Public Class danbrockteams
Structure team
Dim name As String
[Code]....
This works except that my listbox is filled with the team every player is in rather than just listing all possible teams. Not exactly looking for someone to just give me the answer, as I understand things best when figuring them out on my own, so I suppose a hint is what I'm really after.
Several times av been come across of the need of how to create new variables on my application while is running and the next time i will run again the application to be existed in my source code and still be inside.
what excatly i mean is for example i have a listbox with out assigne it in any databound ,or retreive any items from any textbox i just want to insert some items inside
if i go from the designer then i can succesfully add any item i want and they will be there as i declare them.but if i want to to that programmatically i will be able to add them in the listbox but the next time i will run it again it will be lost.until i will select the command again to fill my listbox which is not what i want
in my case i have a datagridview which is running SQL querys and i want if the user selects to save this query i want from some way to save this query string in my listbox . and i want to be there the next time i will run my application with out using any text file or database,
is there any way to that ? i have search before i ask but obviusly my keywords dosen't much with what i was looking for
I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.
View 5 RepliesI'm working with an Treeview and i'm new at it and i have 2 questions.
1. How can i save the treeview items, to settings (my.settings.history)
2. How can i save the treeview items as an TXT or XML file or another exception.
my old vb6 program used to store to ini files now with .net I rekon I need to do something new.. was thinking XML but then in searching around I stumbled apon this my.settings stuff.. so I followed the instructions but something strange is going one..
1. whats the difference between the standard my.settings and adding a new class that is of settings ? anything ?
2. I made 10 new settings in the setting manager but when I try to change then it gives me the old squiggle line saying no go.
I'm having trouble getting the objects of the PageSetupDialog and the PrintDialog to persist in my.settings Is there an example of this anywhere? Seems like it should be something there is a boiler plate for so I can see where I have gone wrong.Added a System.Drawing.Printing.PageSettings and System.Drawing.Printing.PrinterSettings entries in my.settings but even trying to save these form the results of the dialogs they show as nothing with out a error.
I store three items in My.Settings. One is a serialized string, and the other two are GUIDs. When the main form starts, those three items are loaded into various places. On rare, and so far unpredictable, occasions, one of these GUIDs is notably absent. The others may or may not be, I have yet to be able to check. Since it happens so infrequently (twice this month, though I have been working on the code every day), I'm having a very hard time tracking down the problem. However, it got me wondering where these values are stored. I see one of them showing up in App.Config, though without a value. Is there a place I can see the others?
