I could not include the code since it's too large but here is the LINK. I have most of it working. I just need to know how to display the passenger list in the ListBox when the flight number is changed from the ComboBox.
View 8 RepliesI have put about 12 Hours into this assignment and i feel that i have most of it completed what have is a combo box that has a FlightBindingSource and a listbox that has ReservationsBindingSource i need to the selected item in the combo box to be sent to a proceedure called DisplayPassengers, and then DisplayPassengers fills the list box with the passengers assigned to each flight.
This is what i have so far:
Public Class AirlineReservationForm
Private database As New ReservationsDataClassesDataContext()
Private Sub FillAll()
[code]...
I'm trying to complete this airline reservation application, but having a problem in this part of the question:Creat an event handler for the FlightBindingSource's PositionChanged event: select FlightBindingSource in the class Name combobox then select position changed in method name combobox to creat the FlightBindingSource's PositionChanged event handler. Write a code to access the currently displayed flight object and pass its flightNumber to method DisplayPassengers as a decimal.This Is my code so far:

Public Class AirlineReservationForm
Private database As New ReservationsDataClassesDataContext()

I'm looking at building a airline simulation game whereby users create an run an airline, I just want to ask something that will possibly be very simple but it's going to be very complicated answer i think.for every aspect of my game do i have a class to create an object, for example
City: (I'll have a class called myCity and each time i look at a city it goes to that class creates an object and I use it then dispose of the object)Airplane: (make model etc) How about bigger items such as Bank is bank it's own class or are items inside the bank the object?
How about competitors, i guess each one is it's own object? i would never dispose of them, how would I store them form each user session to another?
I'm trying to make a list of flight plans loaded into my program, with each flight plan having a list of waypoints along the route, along with a few other properties associated with the flight plan. Each waypoint has its own associated properties, i.e. waypoint ID, waypoint type, location, etc.
Here's the declarations:
Code:
Public Class WPinfo
Public WPType As String
Public WPID As String
[Code]...
How do I implement the List methods to access the list elements, and add, remove, etc? The way I'm doing it now just gets me an 'Object reference not set to an instance of an object' error during runtime.
Firstly i apologise for another topic on a subject i have created already but this is a slightly different question and not related to LINQ at all despite the fact the code uses LINQ (the linq works fine and creates a List(Of Test) where each 'Test' contains a List(Of TestList) This data could be anything i guess and could come from an array or a database rather than xml literals.Ok, essentially i have a list which contains a list and i wish to display all the properties (List and list within this List) onto a DataRepeater Control. I have developed a testbed to get this working so i can implement it into my main application. Firstly I'll show the current code and how to construct the form and after that i will explain what i have tried and what i have had happen from these trials over the last week.

View 1 RepliesI currently have a list of words in a text file sorted in to alphabetical order and put into lower case, but I would like to be able to also display the line numbers on which these words are associated with.. but only one instance of.
For example,
"This is a random text
file that I
have just made
up this second"

As you can see above, I would like to show that "this" for example appears on line 1 and 4. Hopefully tabbed so that it keeps a nice look to it.
I am trying to understand classes in VB 2010. I am a bit confused with displaying information from a list into a listbox.When I run the following code, the word collection appears in my list box. How do I drill down into 'hostnames' to display the info I want.
Public Class computer
Private _HostName As String
Public Property HostName As String

I want it so every time I click an ITEM in the Listbox it displays ALL the data into the textbox. I know there's an easy way using table adapters and binding the listbox, but I'd prefer to do it this way for my project.
So this is what I got.
Lst.DataSource = ds
Lst.DisplayMember = "tblStudent.FirstName"
Lst.ValueMember = "tblStudent.StudentID"
[code]....
It only adds the first rows details to the text box when I click the second record the first rows details are still there.
I need to produce an error display message when the Windows Mobile PDA is in flight mode. The user will need to pull and push data from a SQL Server server; however when in flight mode this is not doable and a message needs to be displayed. Currently the message that is displayed is:
A request to send information the the computer using IIS has failed. For more results please see HRESULT.
I am programming using VB.Net and I am fairly new to it. I have searched for the past week on the Internet and come across information suggesting that I use TAPI, however I do not know what to import, or where the "flight mode detection" code would go in my application.

View 1 RepliesI'm doing an airline reservation system program, but I can't wrap my head around it. I can't even come up with psuedocode. The airplane has 10 seats. The user needs to choose first class(seats 1-5) or economy(seats 6-10), and I need to make sure that no seat is sold to more than one person. And if there are no more seat in the selected class I need to display a message box "there are no more seats in the selected class. Would you like to switch classes?" else display message " next flight leaves in three hours".
I have more code now!:
Public Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
Dim firstClass() As Integer = {1, 2, 3, 4, 5}
Dim economyClass() As Integer = {6, 7, 8, 9, 10}

I have a combo box, I have entered in 6 different world wide destinations for example:London, Paris, New York etc The program is for booking plane tickets, at the moment the user has to input the cost of the journey manually into a textbox and then depending on the number of tickets requested will calculate the cost.
What I would like to do is to assign a unique numeric value (the specific cost of the flight for one ticket) to each of the items in the combo box list so that when a user selects a destination the default cost of the ticket is already known and does not require the input of the user.Private Sub cmbDestination_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmbDestination.SelectedIndexChanged End Sub The idea is that which ever destination is selected, for example: Paris - �155 would then set the variable 'ticketPrice' to 155 and allow me to change the calculations of the program to not require user input.
What I am trying to accomplish is this: I have a login page were a student logs in. After the login the student will be taken to a student user page. This page has 2 list boxes. The first is showing the exams that he has passed and the other shows the exams he has yet to complete or fail. I can not get any data to display in my list box. If I can figure the first one out I can do the second one easily but I can not get the first one to work. Here is my code that I have so far:
Private Sub Student_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Label1.Text = "Welcome " & _passedText

I am using a ListView control to display Pictures along with description and caption. I used to save the full path of the image in the url field, so when I display them in the ListView I don't need to edit anything. Now I am using something like:
HttpContext.Current.Server.MapPath("~/photos/") + savedURL
How can I edit my ListView to make it show the images?
I used to do the same to GridView when in GridViews RowDataBound event I manipulate the contents like:
Dim photo As New Image
photo.ImageUrl = "~/photos/" + e.Row.Cells(TheCellNumber).Text
e.Row.Cells(0).Controls.Clear()
e.Row.Cells(0).Controls.Add(photo)
I can't seem to get the syntax right for this. I have a structure stored in a generic list and when it displays I get this "GenericList_T_.Form1+stuMotorInfo" in the messagebox. I've tried a few things and get roughly the same thing.
Here is the code:
Option Strict On
Public Class Form1
Private Structure stuMotorInfo
Public MotorId As String

i am making a safari booking system, and i have a combo box list(contains a list of hotels) how do display the prices of the hotels in a text box
View 1 RepliesSo we are just starting to learn about list boxes in vb1. In this program the user enters up to 10 scores and after each input (decInputScore) the total score so far has to be calculates (decTotalScore) and then of course when all the scores are entered, at the bottom the final score it calculated. (decFinalScore) (decFinal). I'm not exactly sure what I'm doing wrong, I can't get it to calculate the correct total scores after each input, and I'm getting 0 as the final score. Here is a visual of what the form should look like: the black square is (btnEnterScore) a pop up message box comes up in which the user enters each value when clicked.[code]

This should, when you are typing in a function, display the "Get or sets the Patient Code" then below that, it should display a list of bulleted items with "Validation:" as the header? Maybe I am doing it wrong, but it doesn't seem to be working correctly.
if someone could help about my Guest Reservation SystemI not intending anyone to do it for me,just need some advice want to know what is better or what should I do to make the project better.
View 3 RepliesI have a list of string. When user inputs chars in, the program would display all possible strings from the list in a textbox.
Dim fruit as new List(Of String) 'contains apple,orange,pear,banana
Dim rx as New Regex(fruit)
For example If user enters a,p,l,e,r , then the program would display apple and pear. It should match any entry for which all letters have been entered, regardless of order and regardless of additional letters.
I have a form displayed where a user can can select a 'function' from a list box. That 'function' has a corresponding ID number which I need to be able to take and use later in the code.The List of functions is preset (about 150+ them and the IDs are already assigned (so I can't just use the index).So if the user selects "Function A", I need the code to set a variable to, for example "42" (or whatever that Funtion's ID is).
I was going to do this using listbox.item and listbox.itemData, but I'm using VB.Net in VS2008 and I understand that function is no longer present (to add ItemData at design time).Here's where it gets complicated. When the form loads it looks at the variable containing the FunctionID and if there is one present, I want it to populate the co-ordinating FunctionName. I can do that if I know the index number, but I don't know how to look at the FunctionID and return it's index (all FunctionIDs are unique).
A) store the info, either in the Listbox using ItemData, in an array (but I'd prefer to do it at design time), or some other way you might suggest.
B) cross-reference the ID and display the name in the listbox when the form loads.
