Making 2 Dimensional Maze?
Aug 25, 2010
I'm currently making a very basic 2d maze in vb.net...How would I go about making the walls to navigate around? I had the movement code down for the most part I'm just having an issue wrapping my mind around randomly generating walls to navigate around. I'm looking to make a basic 2*2 grid.
Edit: I'm not sure if it is necessary for me to post the code I already have written...I just need very general help on how to go about making the 2d 2*2 grid that will be the playable area.

I'm building a maze application in visual basic. The game relies on two variables, X and Y which are integers. There's a timer which basically invalidates the whole form for a redraw. Now my question is, that there are various squares and rectangles dotted around the form. How would I create a handler, or something as such to detect if the square that the form draws is touching these objects?[code]...

I am making a maze game like the one shown in the how to, I recently discovered that if you hold the right mouse button a you can go through the wall. Is there a way to make the mouse lock and not move when the user trys to hold the button down
or
When the user releases the button it resets. Like in the web browser with
If e.KeyCode =
Keys.Enter
Then
e.SuppressKeyPress =
True
WebBrowser1.Navigate(ToolStripTextBox1.Text)
But with the mouse button when it releases send the cursor back to start.

I'm doing a maze using VB10. its about moving a PictureBox between LineShape lines using buttons to move it. the problem is, can I make the picture not to move through the LineShape? if so how? or should I use something else other than the LineShape and another question can i save the progress of the maze and come back to it later? if so does it require using a database to save the location of the PictureBox?

I'm trying to work up a "Pacman" like game. I used multiple (Blue) RectangleShapes to draw a maze on Form1 and added a Timer and KeyPress event to show motion of the Picturebox ("PacmanImage"). The "Pacman" image changes depending on the direction it's travelling (also opens/closes mouth). Up/Down/Left/Right (and closed mouth) images are stored in imagelist1.
The maze has been set up with just enough clearance for the Pacman to fit between the walls. How can I check for any part of a Blue wall (RectangleShape) in the path of the Pacman? - I was thinking to take the position of the PacmanImage Picturebox and check (depending on the direction of travel) for the existence of a blue color in the appropriate rectangle on that leading edge. Ie: left travel would look at a rectangle defined as (x-1,y) to (x-1,y+25) and try to find the color blue where x/y are the top left of PacmanImage and it's image size is 25x25. Not sure how to do all this, but I think it's the right idea...
The ImageList has index/picture: 2/PacDown, 3/PacLeft, 4/PacMid, 5/PacRight, 6/PacUp (Indexes 0/1 are used for two additional pics not used for the motion of the Pac).
Code So Far:
Public Class Form1
Dim LeftRight As Integer = 180
Dim UpDown As Integer = 103
Dim Increment1 As Integer = 5

Consider the following code:
Dim arr1 As New List(Of Double)
Dim arr2 As New List(Of Object)
Dim timeStart As DateTime = Now
For x As Integer = 0 To 1000000
[code]....
It involves 2 lists. The first one is 1-dimensional, the second one is 2-dimensional.The first routine (which operates on the first list) completes in about .015 seconds. The second routine (which operates on the second list), however, takes almost 10 seconds. The only difference is that the second list is 2-dimensional.Is there a way to speed this up or am I doing something wrong? I have a program that requires several 2-dimensional arrays and it's running extremely slow right now. How can I speed it up so I get the same feedback that I'd get if the lists were 1-dimensional?

I have a string containing many lines. Each line has many values separated by commas. Basically it's in CSV format. The number of lines is variable but the number of columns is always 7.
I can get each line into a one dimensional array using Split(Var, Chr(10)).
I'd like to make it a two dimensional array where the second dimension contains each comma separated value.
I've got
Dim VarArray1() As String = Split(VarText, Chr(10))
Dim VaryArray2(0 To VarArray1.Length - 1, 0 To 6) As String
Is there a quick way to get the contents of VarArray1 into VarArray2. I know I can do the following.
For Counter = 0 to VarArray1.Length - 1
Dim line as string = VarArray1(Counter)
Dim Values() as string = Split(line, ",")
For Counter2 = 0 to 6
VarArray2(Counter,Counter2) = Values(Counter2)
Next Counter2
Next Counter
But is there a quicker way to do it that doesn't require passing through each element of VarArray1 and then passing through each element of Values.
The eventual goal in all of this will be to find the highest value in the 3rd column (the arrays are strings at this point because not all columns are numeric). To do that once I get the values into VarArray2 I suspect I have to pass through each element VarArray2, i.e. VarArray2(Counter,2). Unless I can copy the whole third column into a SortedList?

I'm a huge music person (got my own lil record thing going) but I'm wanting to design a program that would make music in my way. I have a decent amount of background knowlege of Visual Basic and Java I'm just wondering how could I execute this whole project. The Project is making a MPC Sampler. MPC is a drum machine; a machine with buttons that once you press it that it will play a sound from a drum (ex: snare, kick, tom, ect.) . So I would want to make some pads on my program that each have their own sound. Total of 16 pads. Which the design wouldn't be hard to make nor would the functionality of it having the play back sound (in my opinoin it wouldn't be hard atleast). But the thing is I wanna map out these pads to number keys on the number pad or keyboard. I'm not so sure how to do that. But that's all the easy stuff...
Also finding information is making a sound directory. What I mean by this is that I want to make a User Interface that will open up a file directory of sounds and the user can select what "kick" or "snare" sound he may want for the kick or snare pad. I don't know how to do that or even know what to search; neverless I don't know if this whole project idea is a good idea for Visual Basic or another programing language.
Also LATER ON I am wanting to add a record and export function that alows users to..well...record and export their beat or instrumental ha. That doesn't seem too too complex (mainly due to the fact that all it needs to do is record the users key strokes and then show them and play the sounds, but obviously it would get more complex than that.)
Here is an image of one of many MPCs but one with a directory - [URL]

I am having a problem understanding the following error message:
Value of type 1-dimensional array of string cannont be converted to 2-dimensional array of string because the array types have different numbers of dimensions This line seems to be causing the error:
New String((13) - 1) {}
I did a Google search on this but didnt come up with anything useful. I didnt even change the code.I just found this example online and copied/pasted it into a project that Im working on.

I've been working on a VB project where I use a 1st drop down list to select a movie category and then in the 2nd drop menu, movies from that category will be displayed. The movies are stored in a 2-dimensional array by category. I've been able to edit my array but I'm having problems with my .AddRange() function. What would I have to put in those parentheses for the list (for each category) to appear in my 2nd combobox when the category is selected?

I declare 2-dimensional array at class level
Dim delItems(9, 9) As String
The array elements are then each set to "EMPTY". I create a new form in memory
Dim frm As New Form
I create a new DataGridView add columns to it and add it to the new form
Dim d As New DataGridView
frm.Controls.Add(d)
Now the problem.....this code give error when try to load contents of 2-D array into DGV:
For i As Integer = 0 To 9
d.Rows.Add()
For j As Integer = 0 To 9
d.Item(i, j).Value = delItems(i, j).ToString
Next
Next
Error is ArgumentOutOfRangeException (Index was out of range...)
When I check value of loop control variables, i = 0 and j = 1

I am trying to set up a number of two dimensional arrays that will be accessed from several forms in the project. I have set up a module to declare all public variables.When I declare the array (Using variables to determine the size of each dimension), when I go to run it, I get an out of index error.If I declare it them as public variables within the form, I don't get the error but then the input cannot be accessed from other forms.Am I completing incorrectly in the module or is there something else I ought to be doing.
The code within the form is
Dim Boardresult(NumBoards, Numteams) As Integer
Dim compass(NumBoards, Numteams) As Boolean
Where NumBoards and Numteams have been input and stored previously.

For my programm I am supposed to store the minimum points in a five-element, one dimensional integer array name points. And I need to store the grades in a five-element, one dimensional string array named grades. These arrays should be parallel arrays. I am supposed to code the display grades button click event procedure so that it declares both arrays. It also should search the points array for the number of points entered by the user, and then display the corresponding grade from the grades array.
Here is my code:
Option Explicit On
Option Strict On
Option Infer Off
Public Class Grades
Private Sub exitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles exitButton.Click

I have an application in VBA that gives to my VB.Net dll one bi-dimensional variant. It is a an array, in which every component is a another array containing two positions.
I want to get this two-position array. When I am using VBA I can access directly the data from each position by doing:dataArray(index, 0) or dataArray(index, 1)And when I want to get the two-position array I can use:
Dim posArray as variant
posArray = dataArray(index)

Compiling the program in Visual Basic Express produces no errors. However, if the program is imported into the Excel Developer environment; I get the following error: Expected: end of statement with the equal sign highlighted. A side comment: About eight years ago, I wrote a Visual Basic simulation program to study financial trends. I found that version of Visual Basic user frendly! I find the 2010 version very difficult for doing simular projects.

i want to make a vb.net program that reads from a text file a movie, with the help of a Open Dialog (called openFD in my program) (we don't know how many movie we've got), the actors, the release date, the country, and the rating.
The text file look like this:
Movie1;Actor,Actor,Actor1;Date1;Country1;Rating1
Movie1;Actor,Actor,Actor1;Date2;Country2;Rating2
...
First question: How can I make a 2-dimensional array? line(0,0) - Movie1, ... , line (1,5) - Rating2. Here Is my try, but it's not good:
Dim line As ArrayList = New ArrayList()
Dim itm As ArrayList = New ArrayList()
Dim i As Integer = 0

i'm extremely confused. my professor gave us this as the FIRST problem to do in this intro to VB class...on page 380 of our text. it is due today and i have been up all night trying to figure out where to even start. i'm so frustrated. could someone please help me and steer me in the right direction? use a one dimensional array to solve the following problem: a company pays its salespeople on a commission basis. the sales people receive $200/week, plus 9% of their gross sales for that week. for example, a salesperson who grosses $5,000 in sales in a week receives $200 plus 9% of $5,000, a total of $650. write an application (using an array of counters) that determines how many of the salespeople earned salaries in each of the following ranges (assuming that each salesperson's salary is truncated to an integer amount): $200-299, $300-399, $400-499, $500-599, $600-699, $700-799, $800-899, $900-999 and over $999.
Allow the user to eanter the sales for each employee in a TextBox. The user clicks the Calculate Button to calculate the person's salary. when the user is done entering this information, clicking the Show Totals Button displays how many of the salespeople earned salaries in each of the above ranges.

I'm having trouble with this specific code and on arrays in general. This is what I am asked to do: "In this exercise, code an application that displays the number of students earning a specific score. Declare a 20-element, one-dimensional integer array named intScores with the following 20 numbers assigned to the array: (88, 72, 99, 20, 66, 95, 99, 100, 72, 88, 78, 45, 57, 89, 85, 78, 75, 88, 72, and 88). Code the procedure so that the user can enter a score from 0 to 100. Then the procedure should display using a message box the number of students who've earned that score."
First off, I do not know what I'm doing wrong with my array.. it says there's an error in line 31 saying "variable intSubscript hides a variable in an enclosing block" but I don't know what that means. And lastly, once that is sorted out, I don't know how to code a message box to appear saying how many students have received that score.
