Making Airline Reservations System?
Mar 11, 2012
I'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}
[code].....

I 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()

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?

We have two systems, one is created in VB.Net 2003 and the other is created in VB6. Both systems are client/server desktop application system. There is a requirement that we need to send and response data to each systems. The data will come as result of process of each system and then transfer it to the other system. These is formatted in a message format. Is it likely to become socket programming? how can I send and response data between servers?

we're working on a billing systemCurrently I am working on the categories module. Here's the thing:I need a dynamically changing UI. So the user can add categories, delete them and teh UI would accordingly add or remove controls automatically.I used DataGridView, but since the fetching and storing of data will not be done in a database, I need to fetch it and update it using an HTTP API, the data bindings are causing problems as I need to update, Insert or delete data using functions instead of letting VB do the hard work. I tried creating a datatable and checking for changes everytime user added/deleted/changed a row, but again the problem is: in a datatable I am not able select what type of control represents the column. For Example I have a parent category column where the control needs to be a combo box. The datatable's columns don't seem to provide an option and are automatically set to text box.I am thinking there is a really cool way of doing this that I am unaware of. all the VB.NET books I have read only seem to use DataGridView in conjunction with some sort of a database and not independantly.

Here's the
Public Class Form1
Function MD5Hash(ByVal strToHash As String) As String
Dim md5Obj As New Security.Cryptography.MD5CryptoServiceProvider
Dim bytes() As Byte = System.Text.Encoding.ASCII.GetBytes(strToHash)
bytes = md5Obj.ComputeHash(bytes)
[Code] .....
The GetMD5Hash's method is using for to decrypt the MD5 hash to turns into the actual strings and MD5Hash's method is using for encrypt the strings into md5... However, the connection strings can be sniff the packets sent out. How to decrypt the MD5 hash and how to blocked the connection strings in the packets sent out??

What the Win32 API is? I have looked around but no where really outlines what it is. Is it basically a set of procedures, outlined by Microsoft for programmers in order to get services from the operating system? In essence is it the equivalent to making system calls abd and library calls in UNIX? And yes I now Windows makes library calls too.

I'm making a custom class that mocks the System.Drawing.Rectangle class because the Rectangle class doesn't have a name property. I need a name property because I am adding all of my rectangles to a collection and I need a little more info stored than just their locale and size. So I changed the _onPaint event but nothing is working out when I run the program?
Public Class Rectanglar : Inherits UserControl
Public BackgroundColor As Color = Color.Blue
Public Sub New(ByVal name As String, ByVal XY As Point, ByVal Widthy As Integer, ByVal Heighty As Integer)

I'm a huge music person (got my own lil record thing going) but I'm wanting to design a program that would make music in my way. I have a decent amount of background knowlege of Visual Basic and Java I'm just wondering how could I execute this whole project. The Project is making a MPC Sampler. MPC is a drum machine; a machine with buttons that once you press it that it will play a sound from a drum (ex: snare, kick, tom, ect.) . So I would want to make some pads on my program that each have their own sound. Total of 16 pads. Which the design wouldn't be hard to make nor would the functionality of it having the play back sound (in my opinoin it wouldn't be hard atleast). But the thing is I wanna map out these pads to number keys on the number pad or keyboard. I'm not so sure how to do that. But that's all the easy stuff...
Also finding information is making a sound directory. What I mean by this is that I want to make a User Interface that will open up a file directory of sounds and the user can select what "kick" or "snare" sound he may want for the kick or snare pad. I don't know how to do that or even know what to search; neverless I don't know if this whole project idea is a good idea for Visual Basic or another programing language.
Also LATER ON I am wanting to add a record and export function that alows users to..well...record and export their beat or instrumental ha. That doesn't seem too too complex (mainly due to the fact that all it needs to do is record the users key strokes and then show them and play the sounds, but obviously it would get more complex than that.)
Here is an image of one of many MPCs but one with a directory - [URL]
