View 2 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:
Option Strict On

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.
I am adding data to two listboxes: listbox1 and listbox2. Now i want so sort Listbox 1, witch i can do with listbox1.sorted = true. But then listbox 2 has to be sorted the same way. (The data has to be matched) How can i do this?
View 1 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.
I have several fonts I want to include in my program to be used, or just want to put them in a folder with my program, or some method of adding them to the program without having to install it on any PC that I want to use the program on.

A. Include the fonts in the program so the program can use them
B. Find a way to have the program use the fonts without them being installed on the PC.
I am trying to make a renaming program, which I have done, but wanted to add drag and drop support. Firstly, when I drag and drop the files into a listbox they appear to be going in and are ordered randomly. I want them to go into the order they're dragged in. Secondly, instead of having the entire path such as:
D:TVThe Big Bang Theory SeasonSeason 1The Big Bang Theory S01E01 - Pilot
I want just "The Big Bang Theory S01E01 - Pilot" to go into the listbox.
the data that its inserted on the listbox comes from a access db i have this code but this only works when theres only 1 line on the listbox this code works fine when i make a search in the db by the code of family(because the family code its a primary key there can only be 1 family width that familycode) so when i get the family surname i clic on it and i get a form telling me info about the family. but if i try to search for the family surname there can be several family whit that surname. when i search the family surname the listbox will show me all the family's that have the surname now what i want its when i search a surname for eg"Smith" the program will display all the familys that have that surname and i want a code that can give me the number of the family i clicked.[code]

I'm adding labels at runtime to my form with a tag. Let's say I have 3 labels with the tags, "1", "2" and "3". I'm adding the tags by counting the labels + 1. When I remove a label with tag "2" from the form there are only 2 left. When I add a new label it will add a new tag "3", but that one already exist. So my "solution" isn't a very good one Although tag "2" is free, I want to give it "4". Any thoughts on how to code this properly?

before you see any of this, you will have made a text file (dont ask how)
the text file will contain html with an unknown number of lines
(the user will click a button to add a new line to the file, so the number of lines depends on the user
each line will look like this:<a href="www.link.com"> text </a>[URL].. is just a place taker for what the user would have written there as well as "text"
