In my game, which is just for practice, I have a 2 rectangles one set as the inner bounderies, one set as a sprite, but I want to create walls for my boundaries. So how could I set a string of bounds with this

I am trying to create a load and save function for my customizable Menu/Tool/StatusStrip controls (see signature). Those three controls use a single AppearanceControl class, which is mainly just a large list of properties (Colors) which control the colors of the Menu/Tool/StatusStrip.
I want to be able to save and load the values of these properties so the user can store them and load others with ease. Serialization seemed the obvious answer, although I never used it before.
Now, there is a slight problem that I cannot serialize Colors, so I simply gave each Color property the XmlIgnore attribute, and created an Integer property that gets and sets the Color property (using Color.ToArgb and Color.FromArgb). This way I can serialize the color properties succesfully.
Then, there is another problem. The properties are not all in the AppearanceControl class. Instead, the AppearanceControl class has a large number of subclasses, which in turn contain the color properties.
As a small example, I may have this:
vb.net
Public Class AppearanceControl
Private _toolStripColorProperties As ToolStripColorProperties
Private _menuStripColorProperties As MenuStripColorProperties

I'm trying to set up a system to resize multiple objects on a form (40+) when the form resizes. I've got it working but it's rather slow, when I resize the form it stutters a lot from looping through the objects to resize them. Is there a better way to do this that would not cause the stuttering effect?

I am about to pull my hair out because I cannot find anything wrong with the code, and I do not get the error when debugging the application in VB! Basically a user enters some medical information on a form in text boxes and adds some medical conditons and medications into two listbox controls on the form, on for medical problems and one for medications they are on. When Button1 (command button) is clicked, it calls a subroutine stored in a module1. Then the application throws and Index out of Bounds error and crashes, losing all information that was entered. Here is the code on Button1:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNext5.Click
Call Store_MedData
End Sub
Here is the code for Store_MedData in the module. The error occurs on red text:
Dim ClientLastName as string, ClientMI as String, ClientFirstName as string, ClientAddress as String, _
ClientAddress2 as String, ClientCity as String, ClientState as String, ClientZip as String, ClientDOB as String, _

I am trying to make bounds for a character that can jump. I have made the character graphic into a rectangle and I have a square block in the game that the character must jump onto and I have set that as a rectangle.
How would I make it so when the character jumps onto the square block, he stays up there and then when he jumps down, and touches the ground, he stays on the ground. My current jump code is standardized; it does not detect changes in the Y-coordinate. What I have done in the jump for the character is I have made it so the Y-coordinate is increased by a certain amount and decreased by the same amount so the difference is equal to 0.
For example:
Character.LocationY += 8
Character.Location -= 8

I created a custom control that uses a PictureBox and made that PictureBox movable.

I have a class, Vehicle. I created two child classes, Car and Plane. I want to monitor the speed, which is a Vehicle Property, and bind it to a control (label, or image, for example) in WPF. When i create a static Class which only purpose is watching the Speed Property, it works, as far as the INotifyPropertyChanged is declared with the Speed Property name.
But the problem is, I have to create dynamicly multiple Cars and Planes by looking in an XML file and deserializing my objects, and creating multiple Car or Plane UserControl (Let's not discuss this way of working, please). So I have to get the Speed property inside the Vehicle Class (which is normal), and I have to get a INotifyPropertyChanged on each Speed of each Vehicle Created. So, my Cars and Planes are loaded, and I have to get all speeds, but I can't create a static Speed property by Vehicle. By the way, by creating a non-static Speed property (as int, for example) in Vehicle Class with INotifyPropertyChanged raised in the setter, it does not work. The event seems to be raised, but my converter is not fired, and my controls does not update.
In my Vehicle Class
Private SpeedValue As Integer
<XmlIgnore()>
Public Property Speed() As Short
Get
[Code]....
The PlaneView Class is almost the same for this part.
I confirm that the converter is fired just once, the first time, when the tabs are created, because I put a breakpoint on the Convert function definition. After that, the converter is never fired again. So the picture img_fonctionnement is displayed, but it is never updated. But the Speed property is updated, I swear. And the INotifyPropertyChanged (in Speed's setter) is raised, as far as i know with the help of the debugger.
And the "an item with the same key has already been added" (which appears in a messageBox, and not as an exception) seems to appear only when I am to long with the debugger. In normal execution mode, it never shows.

My brain is fried at the moment, so here's the scenario.I have a form that adds a member to my VB.NET application.When I press submit I add their details: name and number as well as what products they want (internet and phone). Internet and Phone are their own class as is member.
I want to add that they HAVE whichever they have chosen and with the member store it.

As what happens is once the member is created (stored) I will go to input how much they have used, and then store that. But to do so I will need access to the internet and phone classes, which are associated with said member.
