Placing Multiple Pictureboxes To Different Location By Using Keypress Event?
Dec 19, 2011
I have this code. credits to jmchiney. My goal is when I press a certain key, the picturebox corresponding to that key should be moved to a certain location. Exactly like in the text twist game.
I have a code running and doing what I want but It is only applicable for single letter. For example the word alabama. all letters without duplicates are placed properly but for letter a, only one letter a is being accepted and moved. that goes for all letters.
Here is the
Dim pb As New PictureBox
Select Case (e.KeyChar)
Case CChar(letterPicbox1.Tag)
[Code].....
Another one. when a certain letter is already placed to the location I set and once I press again the same letter, the location changes. What I want is when I already gave pictureboxA a location and then I press "a" which correspond to pictureboxA again it should be stationary and check if there are other letter "a" in my pictureboxes and move the next detected letter "a" to the next position. Like i said. just like text twist game.

randomizing picturebox location given four points example:i have 4 picture boxes. these boxes should be place at points (145, 190) (210, 190) (290, 190) (37, 190). this will display the pictureboxes at a horizontal line. i'm adding a functionality that when i press spacebar or click a button, these coordinates will be randomized and be assigned to my four pictureboxes just like in text twist but no animations.

A while back I made a brickbreaker game with out the bricks. Its a picturebox bouncing on the sides of the form and the whole goal is to keep it from hitting the bottom of the form. Now I'm fed up with that, I want to further myself by adding bricks that I can break and keep score. I have something I came up with, but it will only add 1 picturebox.
Dim pb As New PictureBox
Dim locX As Integer = 75
Dim locY As Integer = 100
[Code].....
I did wrap a try/catch inside the do until. My plan is to add one row, then reset my locX, finally move to a different row(locY) and do the same thing.

I nedd to find a time saving way to controll multiple pictureboxes at once, sometimes 25-50 at once. They are numbered in consecutive order, PictureBox1, PictureBox2, ect. there are over 700 of them in this matrix. Is ther a shorter way of coding their hide, or show function? This is the only way I have to do it.

how to move 5 picture boxes at the same time. Like making them bounce on the walls of the form and each other.
Here is my Code
Public Class Form2
Dim xSpeed, ySpeed As Integer
Dim iClicks As Integer
[Code]....
The problem is that the picture boxes do move but, they move at the same time. For example if Pb1 hits the left side of the form all of the other Picture Boxes will to.

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.

I recently posted a problem with a game that I am making, I have worked on it but have become stuck. I am having trouble with creating an object from my class what I need to do is apply this class to multiple picture boxes so that I can have them moving on screen at the same time. I am unsure on whether or not I have set up the class correctly and am unsure on how to apply it to multiple picture boxes.
This is the class:
Public Class enemycar
Inherits PictureBox
Private speed As Integer
Private xposition As New Random

I create multiple dynamic pictureboxes and it are to many to add them all manually, is there a way I can e.g. use an integer which adds up every time a new picturebox is made. Then I want to add the same code to every picturebox. Now it creates the picturebox and moves it to the next spot and doesn't create a second. I am using this code if its helpfull:

Using the code below I can create multiple pictureboxes dynamically on a form. What I can't figure out how to do is determine when the user selects one by clicking on it. If I use mousedown events I have to hard code in the subroutine the name of the picturebox, which I don't know until the user selects it.
Private
Sub AddNewPictureToolStripMenuItem_Click(ByVal
sender As System.Object,

Is it possible to modify this section of code to select multiple instances of pictureboxes, so that I can drag them all together. At the moment I have to do one at a time, and when there's more than half a dozen, its a bit tedious. I've added the Control key to distinguish it from single drag'n'Drop, but.
'using Left mousebutton and Control to multi drag & drop
e.Button = MouseButtons.Left And My.Computer.Keyboard.CtrlKeyDown Then
newPictureBox = DirectCast(sender, PictureBox)

I 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 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 couldn't manage what the matter is not even after searching. Here my question goes:I need to do a simple task (close my form on pressing escape key) and I use the following code:
Code:
Protected Overrides Sub OnKeyDown(ByVal e As System.Windows.Forms.KeyEventArgs)
Select Case (e.KeyData)
'Close on Escape
Well , it works when I click escape my form closes , but.. if I have pressed by accident or some else matter any of the arrow keys (up , down , left , right) before escape and then hit escape nothing happens. I checked if any other key does that and as I see it does not.

I just want to ask why my KeyPress event is apparently not working. What I want is that when I press the letter m, the selectedindex property of my listboxes would change. Here is the code;
Select Case Asc(e.KeyChar)
Case 13
Try
tray.ListBox1.SelectedIndex = tray.ListBox1.SelectedIndex + 1
[Code]....
I also want to know what the "e.handled = true" is statement for. I set the KeyPreview property of my form to false and true but it's not working as well. the KeyPress event should be triggered regardless of the control within the form that is in focus.

I am trying to create keypress handler that will execute a line of code when Tab, Space, or Enter key is pressed or passed by the scanner gun while the control is in focus. I got it to work with space and enter key but with tab key, the cursor will just jump to the next tab stop without executing the code.
Private Sub Button2_KeyPress(sender As Object, e As System.Windows.Forms.KeyPressEventArgs) Handles Button2.KeyPress

I'm trying to create an application that uses a PictureBox to display an image. I use the arrows keys to switch images and the space bar to rotate the current image. Since the KeyDown or KeyPress events don�t get fired when I click the arrow keys, I had to override ProcessCmdKey. It works fine, the problem is: the applications also has a few buttons and when I click an arrow key the image gets switched but the button�s focus change as well, worst yet, when I press the space bar, the image gets rotated but the button which has the focus gets pressed.

I am trying to add to items to a combobox by using the "enter" key. It does work when I add the first item, but if I manually clear the box and add another items it does not get added to the list.
(1) I click in the combobox and type "hello" and press the "enter" key
(2) I click on the dropdown arrow and see that "hello" is in the list
(3) I select "hello" in the box and erase it, item is still in the list
(4) I type "goodbye" in the box and press the "enter" key
(5) "hello" is still in the list but "goodbye" is not
Here is the code:
Private Sub CopyrightCombo_Keypress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles CopyrightCombo.KeyPress
If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then
[code].....
if I comment the if/end if line and type "hello" the items added to the combobox list are: "h", "he", "hel", "hell", "hello" wich makes sens since the add items is run on every keypress? I know that my commands for adding items is good, I know that my keypress event is handled properly but not when I specify using the "enter" key.

I am using the Event Handler below for the Enter Key Press Event, it is running when ever any of the keys is pressed. This is not so much a problem when the app. is running, unnecessary yes. It is giving me problems when ever I am Debugging using Breakpoints. How can I change the Handler so it only runs when the Enter Key is Pressed, doing away with the If statement?
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
If e.KeyChar = Chr(Keys.Enter) Then
'Different code blocks will run here depending on what
'TextBox or Label is selected.
End If
End Sub
