I'm new to VB. I'm trying to make some kind of traffic simulation for the school assignment. The problem I have is, that all cars show up as one moving car instead of array of cars moving separately.

I can't tell why when my picture box is to show an image the picture box moves altogether, I feel like it might be moving toward the checkbox which I have controlling the visibility of my picture box. That check box doesn't work as it is supposed to either. Everything else works just fine.

Basicly If a user clicks on a picture box it moves around with the mouse, How can I make it so the user has to be holding down mouse1 (draging the picture box) and if they are not holding down mouse1 it drops
View 3 RepliesI have a problem that I can not seem to get. I have a program that moves a picture to what ever location the user puts into the text boxes. It works as I wanted it to but my problem is when a user puts in anything but a number into the text box it gives an error, I want a message to pop up and let them know that a numbers needs to be entered not a text.

I'm working on a program dealing with jagged arrays.Code is below.The FindPath() function works perfectly.It essentially randomly chooses an action from 3 possible choices.The goal of this function is to make it to position (3,3) from (0,0).Sometimes it makes it, sometimes it doesn't.It gives up after 2000 moves.
The PushButton() function is where I have the problem.I want to run the FindPath() function 2000 times, and return the resulting list of moves into intLists()(), my jagged array.I want to use
intRuns = 0
For intRuns = 0 To intLists.GetUpperBound(0)
lstMoveList.Items.Add(intLists(intRuns).GetUpperBound(0)) 'here is where I get the problem.
this section of code to dump the number of attempts it took into a listbox on the main window.I do this at the bottom of the FindPath() function, but that is for testing purposes only.I eventually want to take the successful attempts and manipulate those, so eventually I get the minimum possible number of movements to get from the starting point of (0,0) to the ending point of (3,3).
Function PushButton()
Dim intRuns As Integer
Dim intLists(2000)() As Integer[code]...............
I have VS 2008 and use VB, not C#/C++ or whatever else. I'm trying to make a battleship game, and I've decided to use the only method I can think of to control the grid. A 2D boolean array for position marking. I have the array set up, and the grid set up in the design form, but I can't figure out with all my research how to link them together. I'm writing this program to shake off the rust before school starts again, and for fun. I took VB in school last year, a half year class, so I have a foundation, now I'm self-educating myself above and beyond the class. I've searched for a way to use a picture box array to use the coordinates of the ship to .Visible=True the picture boxes. I've been working on this for 2 days straight with no results. I just need a little nudge in the right direction. The exception I've been getting with my latest concoction of code is NullReferenceException was Unhandled. I think its referring to the fact that I have no idea how to link the picture boxes into the array. Here's my code, and I'll comment where the exception is thrown:
Private Sub cmdStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdStart.Click

I need an indexed set of picture boxes. The number, n, of these objects is determined at run-time.Migrating from VB6!! I had used the load command n times to create a control array from a "seed" picture box. In code the individual pictureboxes are accessed as formula(k), where formula was the name of the control array and k is an integer. Examples can be seen at url... the chemical formulae, Ni2+ etc., are draggable picture boxes (curve captions if you like), so that they can be placed wherever the user wants.How can I implement something similar in VB.NET?

View 4 RepliesI have made a For next loop with an array. I want all my picture boxes to follow each other within the loop. I have currently been using old code, but not in a loop or array format. The old code works. The array code only makes the 2nd picture box follow the FIRST one. It doesn't loop the rest. I have checked the code and cannot determine any mistakes, else I'm missing out on something I haven't been taught.[code]...

I have this sub load up upon form_load event. Yet it doesn't do a thing! I want each picture box to appear on the same row, hence the y axis is set to 49. but I want my X-axis to be added by 30, so that there is a gap of 30 pixels between each picture box, hence the x point is: Xlocation = Xlocation + 30

How do I make a picture box follow a designated pathway. I have made a game where I have several picture boxes that follow each other. and want on of the trails to be able to do its own course. I have noticed that picturebox.left = picturebox.left + 10 works only for going left but picturebox.right = picturebox.right + 10 it saids read only. so I tried doing minus 10, though i don't know a condition how to do it. like how do it make it turn around when it's 10 from the boarder?
View 13 RepliesI want to make a game where the playing pieces can move around. When I click on a playing piece it shows all available moves were I can go like this:
Red represents legal moves and dark gray represents a wall.
I have created a grid and buttons in it. When I click on a button, I subtract or add the available step count to the button index in the grid. For example if my piece can move 3 places, I subtract 3 from the index of the button and get the available position to the left of the piece. Then I do the same for all other directions. It looks something like this:
For each i as button in grid
Select case grid.indexof(i)
Case grid.getindex(currentPlayingPiece) - 3 'Left
[Code]...
Using this method it is very slow and cumbersome to get all available moves and not intuitive to get top and bottom moves. Also if there is a wall in the way and behind there's a available spot it shows that I can move to it.

To make this simple i have a multiple forms. On form 1 is a picturebox whose image property is set through a series of case statements as follows:
If (MyImage IsNot Nothing) Then
MyImage.Dispose()
End If
Select Case cnt_ACerv
[Code]...
The issue is that whenever i navigate away from this form and then back to it the picturebox is glitched and will only appear as a white box with a red X through it. Im sure there is something simple i am missing or a refresh that needs to be done but at this point i am unaware of what to look for. I have checked the variables inside my case statements before i navigate away and after i navigate back and they appear to be correct at both points.
I couldn't find any handles that allow this, can anyone give me a hand?I want a Picturebox to display an image through a URL.

How do you make a program that moves your cursor to a selected color? So you start the program and then the cursor will auto move to the color red (if that is signified).

View 1 RepliesIn my keydown event handler, I am trapping when an ENTER is pressed and i want to advance to the next tab stop as is it was a TAB presses.I am currently using "SendKeys("{TAB"})" and this works but it is a sloppy way to do buisness, as there may be some typeahead keystrokes in the keyboard buffer.
I have also tried going through the controls collection off the form object, but it is too complicated as i am using containers within containers.Another consideration that TAB processing must be taking into consideration is "what if the tabindex is equal to the current tab stop? what if the next tab stop has tabstop=FALSE or is not enabled or not visible.The sendkeys approach handles all these issues but is a dirty approach and has keyboard buffer event processing quirks.There must be a method off some object somewhere that simply moves the focus to the next tabstop candidate.

View 3 RepliesI'm close to getting this to work, but currently can't get any output to display in the listbox. I had it working, but needed to move some things around to get the join function to work.In my program, a user enters input into a textbox and an array is displayed in a listbox based on what they type in. For example, if they type in "a", all foods (in the textfile that is connected to the program) that start with "a" will be displayed.
When there is output, I need to find a way to name this array (which is created based on what the user inputs) and join all of the items in the listbox (example: foods stacked on top of each other in the listbox will be shown at the bottom as a string).I am posting the code that I have thus far; all of the errors that I'm getting (and potentially my logic errors) are just in the first public class until the end of the first if-next statement:

I am successfully able to pull images into a picturebox in my program and manipulate them in a variety of ways. What i need to be able to do is the following.
1) Pull images into a picture box on my main form and dynamically resize either the picture box or the image so that the image doesnt lose its scale when it comes in
2) Have a method of pre-screening an image to be loaded before it comes in so that i can change its size without losing scale .. ex.
if my image is 1200x1200 i do not have that much room on my form so i would want to say something like
if getimagewidth()>600 then
me.picturebox.width = getimagewidth()/2
end if
