Create Point Array From Values In Text Box?
Jun 28, 2011
in order to create fancy custom end caps on the ends of a line, a structure like the following can be used:
Dim pts() As Point = {
New Point(-2, -2),
New Point(0, 0),
[Code]....
be used to create the same point array. I can see splitting these values into an integer array but how would these in turn be placed in a point array of whatever size is defined by the text values so they can be converted to end points of a line that is developed as values are changed in the text box.

I'm trying to extract a piece of text from within the string, defining both a starting point and an ending point. For instance, say I want to search for the text found between "That is a " and " car" in the string "That is a red car", so it would return "red".I know you can use .SelectionStart and SelectionLength, but the length of the word can change, so the selection length can vary. What I want is to establish a specific starting point and a specific ending point from which to extract the text from the string.

how do i create an array with known values for example this is what i want to do
Quote:
dim str as array
str=("!", "@", "#", "$", "%", "^", "&", "*", "(", ")", "~", "_", "+", "|", ":", "<", ">", """", "`", "", ";", "'", ",", ".", "/", "-", "=", "{", "}", "[", "]", "?")
but that doesnt work in vb 2008.so how can it be done without using a for loop and entering each value in step by step Also what exactly does
Quote:
lpText = New String(Chr(0), 100)

I know how to create an array and loop through it normally - but what if I need a multi-column array. e.g. usually I might do something like:
For Each row in NameofArray
Dim name as String = row
Response.Write("Hello " & name & "!")
Next
But what if I want to do something like:
For Each row in NameofArray
Dim name as String = row.name
Dim age as Integer = row.age
Response.Write("Hello " & name & "! You are " & age & " years old!"
Next
If this isn't possible with an array?

i have 18 text boxes with a number in each. i would like to find the 4 highest amounts within theses text boxes. I was thinking i should just load the values into an array and then maybe sort the array high to low and then just grab the first 4 entries in the array after it is sorted.

I am using the following code to create an array consisting of double values specified by start stop and step. The problem with that is that for some weird reason there is a calculation error that seems to originate from the for statement causing the values to drift after the 11th to 12th digit after the comma which is quite irritating for the purpose i am using it.

How could I add array values and populate the results in a specified text box?Then repeat for each line after. Then get a final total.
For example:
1 2 3 4 5 (15)-text box
1 2 3 4 5 (15)-text box
2 4 4 3 5 (18)-text box
-----------------------
(48)-text box

I've noticed through out VB 2010 that when prompted through the intelli window to enter a POINT variable, you can just substitue X and Y values instead and this works. How do you program that option into custom classes?Make something like the code below allow X, Y coordinates to be passed instead of a POINT variable...
Code:
Public Function GetCell(AtGridPoint as Point) as integer
'Returns the cell that the point is located in
End Function

I am working on a way to change either the x or y value of a point and am getting an error while doing so. the code i am using to do this is the following:pts(currentNo - 2).X = pts(currentNo - 2).X - 10pts is a list of Points and currentNo is merely a count that im using to track where i am in the list. I am getting the following error

I'm drawing polygons,lines,etc. and I have to have the points of each precise - up to 12 decimals. Since a Point only takes integer values, I'm not sure how to handle scaling. I have a working user control, but rounding the decimals so I can put them into points is causing incorrect calculations (area, ect.).

I hve been working with points a lot recently, and I have been wondering if there is a way to set a point without setting point.x and point.y separately. For example for (3, 5): Point1 = (3, 5) But that isn't right

Is there such a thing as a type similar to a point, but contains a pair of decimals, or a pair of doubles, rather than integers? I searched the forums and google with no luck. I can't believe this has never come up before, I must have been using the wrong search terms.

I have a background work reading an XML file. I want it to return an array of results which happen to be values.
I want to be able to place all the values as a point on a panel as an X asis which will be lined up with a y+10 pixels on the y axis.
I have the BGW reading the XML file and getting the values. all i need to know is how to return an array list or something similar to a can draw my line graph

I'm trying to create a program which reads a text file into an array.
[Code]...
But that's just silly so how can I fix this? Lines isn't being assigned a null value it's being assigned the first line of text in the file which has text in it so I'm confused.

I am creating a VB.NET application that uses multiple lines of a text files as an array member. I came up with this code to create the array:
Dim PSArray as string = Split(my.computer.Filesystem.readalltext ("E:PS.txt") )
Now that I have created the array, I need to know how I could make each line of the text file an array member.

I'll explain what I'm working to eliminate the assumptions of a brute forcer. I'm working a Random SQL Data generator. What I need is a way to create a multi-dimensional array from multiple word lists, 1 dimension per word list. I have tried a few different things and nothing I've tried works. However, I have got it to work with a single word list and an array of 1. I figured there is a more efficient way of doing this than writing a massive block of select case and using multiple 1 dimensional arrays, this would end up very messy and inefficient it seems.No this is not for homework, this is for personal learning use only.I would post my code, but like I said, nothing I've tried comes close to working.

I have 81 text boxes on a form and would like to create a text array in code that will equate to these boxes on the form. Once I've assigned each text box from the form to the array entry, I'd just like to work with the array - then have the actual text boxes on the form reflect the changes made to the array.

How would I manually create a reparse point in a file and do all that stuff. I read up on how but it didn't make enough sence for me to comprehend on how would I visually show where to create the reparse point. I understood that it had to do with storing part of the file in memory for fast access and giving it a name to access it faster.[URL]..

I'm writing a tool that will have -at some point- to create a torrent. Now the tool is big and 'creating the torrent' is only a small part of it so I thought I can use a command-line utility that creates torrents but sadly it seems that there are no such tools available for windows ( found some for linux ). What are my options here? Should I just write a tool that creates torrents out of directories (I don't even know how a torrent file should be structured)? Or is there a way to control a GUI-Based application using my VB.NET program? ( Guess only C can do that, right? )
