How to sort data in ListBox?
View 2 RepliesI have an application that receives data input from an automated set of devices. This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.[code]

I am trying to add up numbers in a listbox.I know how to add them up and make them display on a messagebox but what I cant do is add the numbers in one listbox and then add the numbers in another listbox and subtract the total of the numbers from 2nd listbox from the total of the 1st BUT instead of displaying them on a message box how would I output those results into a label?This is the code I have for outputting the totals of a listbox onto a message box:
------------
Dim intTotal As Integer = 0 'Running
Dim intX As Integer = 0 ' Index Position
For intX = 0 To lstDebitsBalance.Items.Count - 1

btw the name of the second listbox I want to sum up is lstCreditsBalance

View 3 RepliesI have a functioning program that has been completed that based on miles and gallons used, both will display the individual MPG for each single entry as well as compile a total for the miles, gallons used and overall MPG at the bottom.My problem is that when 0 is entered for fuel, the MPG calculation says Infinity and 0 is placed in the gallonsUsedListBox.I've been trying to get the statement "Gallons must be greater than zero" into thegallonsUsedTextBox by utilizing an If..Then statement but to no avail. I'm not sure where to input it or if my avenue of using the If..Then statement is even on track. Here is the code I have:

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

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.
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.
My problem with my project so please help me about I am enclosing my project with problem very simple but I can't found. I am using text box and listbox last two textbox i.e. txtlani and maskedtextbox.
Now the problem is when the user put the data into above mentioned two text boxes for the selected item of the list box I want to change the back color and If the user wish to leave blank that two text boxes then no change at all in the list box selected item.
In short that if Textbox leave blank then no change in the selected item back color if in the Textbox have some value than selected item back color change.[code]....
How 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.
im trying to replace data from listbox1.selecteditem to listbox2.selecteditem i have a temp.txt text file that loads in to listbox1 (rlines) this is the methord i use to load each file in to a list box...

Dim file_name As String = tempdata()
Dim stream_reader As New IO.StreamReader(file_name)
Dim line As String
[code]....
it dose what it says and replaces that line of text from the data loading in to listbox2 with the data i selected in listboz1(rlines) but what im looking for is to have the data load in to listbox2 and then have a button so i can select a line in listbox1 and in listbox 2 and it will replace the line from listbox1 in to listbox2 now i can add a line in to listbox2 from listbox1 with

View 18 RepliesTwo listboxes data to correspond to each other
View 1 RepliesAm just goin on 3 weeks of teaching myself vb2010 and have found a long way to do a simple task. Well it seems it should be a simple task. I have about 12 different listboxes spread over 3 different tabcontrols. There are 3 buttons that load all the listboxes according to which tabcontrol they are in. I found that when populating the listboxes it would not clear before loading the information so it would basically double post, triple post etc. I've figured out one way to do it that I've put in a sub and call the line before the tabcontrols are populated with their listboxes. Here is the sub:

It seems like a longwinded way to do this is their an easier way to have one command clear all listboxes within all tabpages within all tabcontrols on the form??
I have three listboxes in an array and on form_load the listboxes initially select the fifth item in each listbox:

I am wondering if anyone else has experienced any issues with adding a data source to a VB.NET 2010 solution using the 'Add New Data Source' wizard. I am getting a very odd behavior when i add the data source, I see a .xsd file is added in my solution explorer but I do not get a data source listed in the data source view. In short, it will add a dataset to the project but will not add an entry in the project data sources. I realize I can code to get the same results but purely out of convenience I would much prefer to just use the wizard and the corresponding table adapters it generates as I always did.
By the way, a google search shows that many people had similar issues in the 2005 version but their issues involved trying to use special characters in the project path (i.e. 'C:My ProjectsR & DMy Tool. I do not use any special characters in my project paths and yet am still experiencing this issue.
I have a program that has to store a pre-made array that contains strings (moviename, moviegenre).
I setup all the items in the array already, example:
moviearray(0,0) = "Green Lantern"
moviearray(0,1) = "Action"
For this example, if the user selected "Green Lantern" from my listbox, then the label needs to display "Action". So yeah, it's a 2-column array: first column = movie name, 2nd column = movie genre. Now, I have a listbox containing all of the movie names (not entered by the array, but entered through the Item property of the listbox). When a selection is made in the listbox and a button is clicked, I need to have the genre of the movie output to a label. That is where I am stuck, I just can't figure out to compare what's in the list box with the first column of the array to output the 2nd column to the label.
I have a listbox with multi-select turned on. I want to transfer items from listbox 1 to listbox 2. The following code supporting the "Add" button works for an example where you are not using multi-select. How do I modify it to accomodate multi-select?
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
If Me.ListBox1.SelectedItem IsNot Nothing Then
Me.ListBox2.Items.Add(Me.ListBox1.SelectedItems())

View 3 RepliesI'm trying to sort items in a ListBox in a WPF project in VB 2010. I tried searching the web but I couldn't find a code that works (maybe I'm doing something wrong). Here's what happens everytime the user clicks on the button The timer "Generator" is fired The code in Generator_Tick make 6 random numbers (no duplicates), and adds them to ListBox1 Here I want the Items in ListBox1 sorted so Every item in ListBox1 is added to TextBox1 (in the order in which they are in ListBox1)This is just a test project so I didn't give the components a name):
Here's my code:
