Ignoring Lines Containing Certain Numbers (Code Included)?
Dec 3, 2009Basically I want to have a lines that contain certain numbers ignored. Where lines that do not contain those certain numbers show up in textbox1.text.For Instance.In the code I want it to ignore all lines that contain "1234" and "1645" when it reads Accessed.txt, and output every line that does not contain those numbers. So if a line contains "78910" it would output that line into textbox1.text.Here is what I have so far, and it works as long as I only have 1 if not contains statement. When I have more than one, it doesn't work at all and just outputs everything in the text file.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles Button1.Click
Dim r As New System.IO.StreamReader("S:accessed.txt")

Nov 5, 2009I am trying to learn about arrays and the for next..loop. This is a noob question but I cant seem to get it to work. I am trying to load an array with 30 numbers that print to a list box.

VS 2010 Declare All Numbers In An Array Without Going Down List One By One
Feb 26, 2011So I have an assignment dealing with arrays for school but first I will start it off with the simple question as to where I am stuck now. I was wondering what the simplest way is to declare all the numbers in an array without going down the list one by one ( ArrayA(1) = 1, ArrayA(2) = 3 and so on.) I was wondering if the simplest way to do this is just by putting: ArrayA = ArrayA += 1 or what the simplest way to do this is.
View 6 RepliesFind Duplicates Within An Array List Of Random Numbers?

View 2 RepliesVS 2008 Generate Numbers In List Box?
Dec 8, 2010Create a GeneratedNumber application that stores in an array with indexes 1 through 100 numbers generated by the index values when Generate is clicked. Generate the number to be stored at each index by summing the index and it's individual digits. For example, 25 should be stored at index 17 because 17+ 1+ 7 = 17 and 4 should be stored at index 2 because 2+ 0 + 2.
Your program should use a FillArray() procedure to generate the nuymbers and DisplayArray() procedure that displays each index and its element in the list box.

Use .next (random Numbers) To Randomly Select Something From A List Of Numbers But It Can't Repeat The Number?
Aug 16, 2009So how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:
dim num as integer
dim r as new random
num = r.next(1,5)
if num = 1 then
elseif num = 2 then
etc.
That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open. It brought me inside of the folder so I tried to open the game but there is no form1 there. It says the games name then .exe in the explorer-like thing in the top right?Also, how would I have a value or something in a label and access it from a button.
Example:This is in a label.
Dim number as Integer
number = 0
Then in the button do
Label.number = 0
How would I do something like that? I want to use that a lot as I did in a different language.
Program That Will Compare Array Of Grocery List Items Glist And Array Of Coupon Item List
May 27, 2012I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

VS 2008 Array Vs List?

View 7 RepliesVS 2008 - Two Dimensional Array / List Or Collection
Jan 29, 2010Is it possible to have a two-dimensional array/list/collection such as the following. The first dimension is to have 2 elements, 0 and 1. The second dimension I would like to be able to have a different number of elements for each of the elements in the first dimension. To explain better, I'd like X in array (0, X) to go up to say 4 and Y in array(1, Y) to only go up to say 2.
So there would be:
array(0,0)
array(0,1)
array(0,2)
array(0,3)
array(0,4)
array(1,0)
array(1,1)
array(1,2)
But no array(1,3) or array(1,4).
I'd also need to be able to use Redim Preserve to increase the size of the second dimension for each of the first dimension's elements.
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.

C# - Count Occurences In Byte List/array Using Another Byte List/array?
Jun 20, 2011I am trying to get a count of all the times a byte sequences occurs in another byte sequences. It cannot however re-use a bytes if it already counted them. For example given the string let's assume the byte sequence was k.k it would then find only 3 occurrences rather than 5 because they would be broke down like: [k.k].[k.k].[k.k]. and not like [k.[k].[k].[k].[k].k] where they over lap and essentially just shift 2 to the right.
Ideally the idea is to get an idea how a compression dictionary or run time encoding might look. so the goal would be to get down to just 2 parts, as (k.k.k.) is the biggest and best symbol you can have.

Add Every Combination Of List Of Numbers
Nov 1, 2010VS2010
VB
I would like to be able to add every combination of a list of numbers to determine which combinations equal a specific result.
Simple Example:
List: 2, 4, 6
Result: 10
How many and which combinations of numbers result in the number 10? The correct anwser is only one which is 4 + 6 = 10. The example is simple but the actual list may contain as many as 10 - 15 decimal numbers.
I have thought of the following as a possible way of checking each combination by using binary:
- There are 3 total number so the possible combinations would be:
123 - Three numbers
000 - Add no numbers
001 - Add the last number
[Code].....
However, I don't know how to actually match up the bitwise bits to the numbers in the array to actually add. Example:
101 - I should check if 2 + 6 != 10 per the example above so this wouldn't satisfy the result... does this make sense? The answer would be 4 + 6 = 10.
how to check and add all combinations from a list of numbers to determine if the result is a specific number?
