View 1 RepliesDeclaring Jagged Or Rectangular Array
Sep 21, 2010I'm working on a reporting section of code for an inventory app I'm making for my office.I call a text file, read every line into an array then populate information pages with what has been pulled from the text file.For reporting, I want to read every text file in the directory, reading each one into a multidimensional array.Thus I can call and report on each item, i.e.ItemArray(i,2) would be all systems with Windows 2008 EE..I have code that lists all files in the desired directory and counts each file, so I eventually get counts of how deep I need the first level of the jagged array to be. but not until after code execution. Basically how can I write each array of data to the jagged array.[code]But I get a null reference exception. "Use the new keyword to create an object instance".

VS 2008 Create Rectangular Array From List?
May 25, 2011i read data from a textfile into a one dimensional array (string()) and refer to that later on to build a new list with just the lines i want. using chartData as New List (of String) I can load the List collection just fine. Now, I want to send the output to a table so I can bind it to a datagrid. using Split and AddRange breaks the one dimensional data up into new rows but I want this sort of thing:
"Row0 Cell0"->"Row0 Cell1 "->"Row0 Cell3";<line break>
"Row1 Cell0""Row1 Cell1"Row1 Cell3;<line break>
Note I provided for characters that can be used in a split function (-> and vbTab), which works, but the split in the List gives me a one dimensional array.

Microsoft.Office.Core.MsoShapeType. But couldn't find it.

Algo / Code To Cover A Rectangular Area Using Circles?
Jun 13, 2012This is a problem like the puzzle - "find minimum number of coins to completely cover a piece of paper".
The difference is:
in my case RADIUS of the coins is variable (but all coins should have same radius).
Real scenario:
1. I need to draw circular shapes on a rectangular image.
2. Number of circles (N) is CONSTANT/ User input
3. Size of image (S) is CONSTANT/ User input
4. The program should find the MINIMUM RADIUS (R) that is needed to draw N number of circles on an image of size S, so that, the image is completely hidden behind the circles.
This is NOT a puzzle/assignment that I'm trying to solve.This is part of a larger project that I'm working on.
I don't need any drawing code. I just need the code/algo to find the radius.
VB 2010 Array/write Array To File?
Dec 3, 2011I'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:
Public Class frmFoods
Dim foods() As String = IO.File.ReadAllLines("foods.txt")

Mutating An Image - Alter A Rectangular Portion Of The Image?
Mar 21, 2011I have a bitmap displayed in a picturebox.The bitmap is a moderately complex image. It isn't a solid color, nor is it some repeating pattern,but it is a picture with a very narrow range of colors (all blue).I have a way to alter the whole image in a suitable fashion to indicate that it has been selected.What I would like to be able to do is alter a rectangular portion of the image in some way.Ideally,I would be merging in a semi transparent color such that a segment of the image would have a different appearance to it.

VB 2010 Fibonacci Using An Array?
May 21, 2011The assignment is this: User inputs the number of fib numbers they would like displayed. The program takes this number and produces that amount of fib numbers using a function and an array. Function can not display the results, that has to be done in the button's click sub.
Now, I really thought I had this array stuff nailed, I have done the random lottery number program and all that... but I think somewhere along the time it has taken me to get this messed up code I have written, it has also confused me to no end. I started off just being confused about how to display all of the variables in the array, now I am just not sure what is going on. I have successfully written this program without the use of an array prior to this.
