Pictureboxes In Runtime Stop Them Colliding
Apr 16, 2010
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.

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
[Code]....
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.
Private Sub BtnRepeatCubDes_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnRepeatCubDes.Click
Try
intPicBoxCount += 1

Dim picEnemy(9) As PictureBox
Dim enemysprite As Image
enemysprite = Image.FromFile("....gif")

Recently 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.

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?

Alright, so I'm still working on the slot machine. I have three timers all independently going for my three "wheels" of the slot machine.
My issue, is that I'm trying to make a Stop button to stop each timer one at a time, and I'm not understanding why this code isn't working. The logic completely makes sense, and the first "wheel" stops when I click the button, however, it doesnt appear to stop the other two timers.

I created a form and have the variable inputs for 4 motor run statements. Then with a start button the script starts and it is surrounded by a for next statement to loop 10 times. It works fine but if i need to stop the execution of the script with a stop button. I put the stop in a new section but of course does not work to do a motor stop. It just causes the exe to not respond till the loop is complete. Just need to be able to stop the Run1_Click button section.
Edit:I do not mind if it finishes the 4 motor run commands and then stops execution of the loop. So need to figure out a way to trigger a stop from a button on the form to stop the cycle. For the future the loop will be a variable integer input so 10 will not be the standard.
Edit::Does a ' Do ' statement sound like the thing to use? If so how and where would I place that? Have a Stop button on the form and it would stop after the 4th motor run command.

I have a START and STOP button and when the user clicks "start" the program does a whole bunch of calculations and all. However, I noticed that when I was testing the program I clicked STOP the program continues to execute stuff.
My START code is basically a while loop that iteratively does some calculations.
So I just put a boolean variable as the while condition and when user clicks stop its set to false and when user clicks start its set to true. However, when I click stop, the condition is set to false yes but it still executes all the code until the condition is re-evaluated right...so my question is how can I get out of the while loop when user instantly clicks "stop"?

I need to record the screen when my user clicks start, and stop recording when he clicks stop.I've searched for a while on this subject, and I have found nothing.I want to do this without adding any files to my project, I just want to use some built in function in Visual Basic, and start recording, or even take a snapshot and add it to an AVI file or something...These are some sites I have found:

what i'm trying to do is make sort of a picturebox game. I have a picturebox name p1 that i got to move with the arrow keys on the keyboard. What I was tryna do next was to have it so that whenever I pressed the spacebar on that a new picturebox would be created, originate from p1's location and then go up 5 pixels at a time. so here's my code that i tried;
Dim Loc As Point
Dim shot2 As New PictureBox
If e.KeyCode = Windows.Forms.Keys.Space Then
shot2.Visible = True
[code].....
I have that under the keydown event by the way. So even thou vb didnt have conflicts with my code. But when I press the spacebar nothing happens.

I am developing a Blackjack game in VB.Net using Visual Studio 2008. I have Picture boxes to display the players cards. The issue I have is that when the player chooses to hit , the third card stacks properly over the first two, but on the forth hit,the picturebox(which contains the forth card) appears under the third card. The same happens for the fourth , fifth, and sixth card . I have looked at the properties for the picturebox hoping there was some kind of index (similiar to zindex in css) to order the cards so they would would "stack" on top of one another but leaving the numbers of the cards visible, to no avail as I am here posting I have a screenie of the situation to better illuminate my struggle.
If you look at the picturebox with the 8 of diamonds card in it , everything is fine, but you will notice that the 10, 4, and 8 of clubs is underneath. I would like these cards to stack as the 4 of clubs, the 9 of diamonds and the 8 of diamond did.

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.
