Creating Moving Object In Rectangle Box?
Mar 20, 2009
1. I have created a moving object (which is a button) in a form (rectangle box) called "Enjoy Button" and it moves when
2. A specific button named "Start Timer" is pressed...When the "Start Timer" button is pressed,
3. The "xTimer" event is called and the button moves in a rectangle box and bounces of the walls...=animation
4. However, i need to write a For..Next Loop in the
5. "For Next " Button= a button named for next
6. And also put a counter in the loop to control the animation time..
7. The loop should stop at a certain time, and the object too should stop at that time,at a new location
This is what I have so far
Private Sub ForNextButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles xForNextButton.Click, xTimer.Tick
Dim MyTime As Integer = 5
Counter = 1000
For Counter = 0 To 1000
xTimer.Enabled = MyTime * 1
' Move the button for a set amount of time
' Exit the loop
Next

It is my understanding and experience that VB.NET does not perform well with moving graphics from point A to point B in a form. How do I draw a rectangle or a line and move it from point A to point B? Is there a reliable way to do this without seeing a black rectangle around the moving object on every frame? I've tried this with bitmaps before but it doesn't work. I see the frame rendering and it's way to slow. Perhaps there is an animation Control or library?

I have this
Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
lblText.Text = rectangle1.X
If e.KeyCode = Keys.Right Then
rectangle1.X = rectangle1.X + 5
[Code] .....
And the text changes but the ractangle doesn't move... What can I do?

how I could have an object bounce back when it collides with an rectangle shape. There are multiple rectangle shapes and I don't want to do it all seperately for each one.

I know how to create the Rounded Rectangle, but what i don't know how to do, is make the area outside of the rounded rectangle (the corners) become transparent This is going to be used on a usercontrol, so i really need it to be transparent and not just blend in (ie adapt to the colour of the parent form).

How can I constrain the bounds of a rectangle object, which is controlled by a mouse, so it cannot be drawn outside a PictureBox? It is kindof a standard lasso control, the user can click and drag and it will draw a box from the initial click point to the mouse's current location. The starting point is at (rectX,rectY), and the box is drawn to the bottom right using rectDimX and rectDimY (to set the width and height) to see how much of a change has occurred with the mouse. Basically, its what you get with a click and drag on a Windows desktop. The issue here is that the rectangle is able to be drawn outside the PictureBox it is being drawn on, and the next part of the code attempts to reference this location, and then fails with an OutOfMemory exception. This leads me to my second question:

If I have a very large function/sub in a class that is an instance method (i.e., not Shared), do I gain or lose anything by moving that to a shared method and then declaring a small stub method for the instance use?
I.e., I go from this:
Public Sub MyBigMethod(ByVal Foobar As String)
If String.IsNullOrWhitespace(Foobar) Then
Throw New ArgumentNullException("Foobar")
End If
[Code] .....
My thinking is I save on memory size per each instance of the object. Because each instance only has to lug around the stub method which handles calling the shared version and passing an instance of itself to the shared method so that it can do whatever it needs to do. But I'll wager that I sacrifice a very teensy amount of speed because of the added function call overhead.

I'm having this problem with my code and cannot seem to get past it although it was working fine before. The error is "An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object." The code is:
CODE:
I am trying to get information to be pulled out of a database and show in text boxes on another form (frmviewsdets). The error occurs when it gets to the line frmviewsdets.txtsnumber.Text = rdr("StudentNumber") and even when a breakpoint is applied there it just moves on to the next and so on.
I have tried to show frmviewsdets before I pull the data out of the database beut I get the same message.

I'm trying to make a picturebox move left by 5 pixels when i press the left key. I am completely lost right now to be honest, and I've been trying to figure this out for the last 4 hours. I haven't done VB in two years, so feel free to crucify me on my mistakes, I learn better that way.[code]One thing I am wondering, is if I have to hardcode the picture box into my form?

I am creating a game where on clicking the start button the object below it moves across the screen a bit further with each click of the button. I used VB at college way back in 2003 and am extremely rusty. I am guessing I have to change the X value of the Location property to make the Picture Box move horizontally across the screen, however I have had no luck so far!

I'm trying to create a small game in VB2010. The gameplay is as follows:
civilians would walk/stand in a room/street and suddenly an evil character would pop from the ground/wall. This evil character would suddenly vanishes too. So, the player has to shoot it to kill the character. The evil character, civilians, etc. would be random. Also, there would be sound effects too. That is the popping up of the evil character, it's voice, the civilians voice, etc. I'm trying to make it as simple as possible but without degrading the quality of the game play. I think, I could somewhat create the graphics for the characters, scenes, etc. and can get the sound effects recorded.
So, the difficult part is,[ ] how could I make it a smoother for playing the game ?
[ ] what would be the best way to do animations ?
[ ] Creating a GIF and placing it in the picturebox and moving it ?
[x]how to play the music in background and at the same time play sound effects on certain instance ?

Given a rectangle of width w and height h. and a coordinate x,y in that rectangle I would like to identify which triangle I am within.
i.e. the function should take parameters(x,y) and return a,b,c,d or a zero based number representing that triangle index i.e. (0=A,1=B,2=C,3=D) if they are in that order.
I think this would be something like >= the formula of the red line and >= the formula of the green line?
I'd like to implement this in VB.NET

Trying to write a very simple game moving PictureBox2 around with keys and when it passes over another object such as PictureBox1 the score is incremented and then PictureBox1 is disabled/removed. Problem is that it disappears but every time you pass over that area it still increments the score further as if the object was there still.
Here is current code, but have also tried hide, dispose and Controls.remove with no luck.
If PictureBox2.Bounds.IntersectsWith(PictureBox1.Bounds) Then
score = score + 1
Label1.Text = score
PictureBox1.Enabled = False
PictureBox1.Visible = False

I am having some trouble creating an object array of different object types. Here is what I have so far:
Public Sub New()
Dim b1 As New Book("Book Title 1", "Gold Book Publisher", 1.0, "Bob Jones", "192DJDJD212", "01/02/10")
Dim b2 As New Book("Book Title 2", "Gold Book Publisher", 1.0, "Bob Jones", "192DJDJD212", "01/02/10")
Dim b3 As New Book("Book Title 3", "Gold Book Publisher", 1.0, "Bob Jones", "192DJDJD212", "01/02/10")
[code]....
If I define the array As Book (Public publicationArray(6) As Book) or Magazine (Public publicationArray(6) As Magazine) I am able to access the properties of that class but not both. I think I need to define a type for each array instance but not sure how to do this.

So programmatically speaking, what is the main difference between the two set of code listed below.

In the code below (which I just wrote here - it closely mirrors what my actual code is...) the problem is with the line:
Thing.ThingObject.Add(MyObject)
It says: "Object reference not set to an instance of an object" Yes - it is "nothing" before I try to use the Add method so I must be doing something basic and wrong.The object I am trying to add is fine - I can tell you it is correct, it's just that I apparently cannot use the .add method on the Thing.ThingObject until it is properly created - which I have apparently not done.
Private Sub DoThing()
Dim MyObject as New Object
MyObject = MakeMyObject
