im making an array of pictureboxes at runtime:
Dim picEnemy(9) As PictureBox
Dim enemysprite As Image
enemysprite = Image.FromFile("....gif")

i get the error:Object reference not set to an instance of an object.
now i know the error would be solved if i had:
dim picEnemy as New Picturebox, but i cant since its an array
im doing a project in which im basically trying to make an etch-a-sketch style program.
I am using a 5x5 pixel picture box as the 'cursor' and have made the program so that i can move the picture box with the arrow keys. I am currently trying to work out how to make a trail of identical picture boxes (from an array of picture boxes) appear wherever the cursor has been using this code
Case Keys.Left
CurrentLoc = New Point(PictureBox1.Location.X, PictureBox1.Location.Y)
If Not PictureBox1.Location.X - 5 < 0 Then

Basically, im trying to make a trail by moving the original picturebox and the inserting an identical picturebox in the original's previous position. However, the new identical ones do not display
Having created my picture boxes at runtime, I am able to drag and drop them, but I have a few technical problems. After a few days of 'playing' seem to be going around in circles.There are three main problems:-
1. The last picturebox created is the only one I can drag.
I tried using "CType(sender,PicBox)" but never got it to work successfully.
2. The picturebox moves to the mouse cursor whenever I click it.
3. There seems to be an offset from where the cursor actually is, to where the picturebox actually moves.
Heres what I have so far.

I have code my pictureboxes so that I can move them around my form, however i can move a picturebox under another picturebox. Basically What i would like to be able to do it for a picturebox not to be able to go underneath another picturebox and thus dissapear.For example my picturebox 1 when i move it can go under my picturebox2, I would like it to touch the edges of picturebox2 at most but not go underneath it. I am using visual basic 2008.

View 1 RepliesRecently I have been wanting to learn a bit more about Visual Basic and I've decided that I want to test my abilities by Making a Card game. The card game uses a customized deck of around 140 card. The Cards are all buildings which you need to place down by discarding a specific amount of cards in yoiur hand. The Objective of the game is to get 12 buildings built and get the most points. Many cards will be layed down at some point in the game.The way I think I will be creating the game is by Creating a Class for the Deck which will use a class for the Card. I would like the Card Class to somehow create a picture box of the cards image on the form which will hold all the other cards being displayed.

View 11 RepliesI wonder how you can make a picturebox selectable at runtime and also change the size and location during runtime?
Well I know how i can change the location of a picture box during runtime but that is only with a picturebox that is already defined in the form before runtime.
So I write an event for that particular Picturebox.
But now i want to do the same thing with a picturebox that a user can add during runtime and then the user should be able to select and move the picturebox.
So now i can't add code to the picturebox event so I wonder how you should do this. ( Maybe with reflection?)
And what if the user added 10 picture boxes and selects a certain picturebox. How do you make it possible that the picturebox the user clicks on is selected?
Should you store each picture box location on the Panel and then when the user clicks on a certain pixel in the panel where a certain picture box is it get's selected?

I have 5 pictureboxes on my form and would like to but then in a collection or array to use them in a loop. I would like to use the FOR EACH loop... but how..
Th pictureboxes are placed in a Table. Here is my code so far.
Dim TableHeaders As String() = {"PERIOD", "GRADE", "SUBJECTS", "POSSIBLE ATTENDANCE", "ACTUAL ATTENDANCE", "% ATTENDANCE", "DISTICTIONS", "NUMBER ENROLLED", "STUDENTS WRITTEN", "STUD PASSED", "% RETAINING", "% PASSED", "TERM MARK", "NAT AVERAGE"}

It says that PictureBox is a type and can not be used as an expression, so how do i do it?
I'm making a game which involves putting an array of picture boxes in a panel. I can see the picture boxes, but some are cut off where the panel ends. I have also used:
My_PictureBox(Row, Column).SizeMode = PictureBoxSizeMode.StretchImage
I have text for ToolStripStatusLabel1.Text in a file which is read into an array.
There is an array of PictureBoxes, which are used for the MouseEnter event.
I am trying to display different text in the status when the mouse is over a certain image. In the code below, the Array.IndexOf() generates "Index was outside the bounds of the array.". The commented line will change the text when I change the Index but, it changes it for all images.
How to place units and their men on the form but I cant seem to get this array to work. It has multiple errors in it.
Dim pic(calctroops()) As New PictureBox
Dim z As Integer = 15
For i = 0 To Form3.orcunits
For x = 1 To Form3.orc(orcunits)
z = z + 15
pic(i).Location = New Point(Orc1.x + z, Orc1.y)
pic(i).BackColor = Color.Green
Me.Controls.Add(pic(i))
Next x
Next i
I have a VB2005 project that displays 16 pictureboxes in a 4x4 grid which display CD album covers. In VB6 I could set up a control array i.e. picCD(0) to picCD(15), which made drawing the CD covers a snap. How do I accomplish this in VB2005?
It seems extremely cumbersome to have code like: If Len(path(0)) < 1 Then
If Not IsNothing(PictureBox1.Image) Then
PictureBox1.Image.Dispose()
PictureBox1.Image = Nothing
End If

I was wondering if it was possible to make an array of a class. I made a class called creatures (for a game of course) and wanted to make an array of that class. So I tried "public creature() as new creatures", and it had a problem with using an array with new. Is there a way around this. All I am using the class for is variables. i.e.: in my class all i have is dim health, defense
