Convert A Long String (Lets Say 550 Chars) Into Something Lower?
Mar 3, 2011
I'm trying to make a hash calculator (For testing now)
I know that MD5 is a 1 way(Meaning that there is no decryption for it, yet)
now I was wondering if SHA-1 is a two way. Also, is there any other hashing method that are 2way?
reason is that I want to convert a long string (Lets say 550 chars) into something lower (From 550chars to something lower then 550chars)
I can use a Key, but every possibility will give me bigger length then the actual string.

I want to convert a List (of Long) into a string array.
Reason: it's a list of database IDs and I want to make a comma delimited string to pass into a stored proc.I tried this:
Dim commaDelimitedList As String = String.Join(",", itemIDList.Cast(Of String)().ToArray)
but I'm clearly not using the Cast correctly since it throws an exception:
System.InvalidCastException: Unable to cast object of type 'System.Int64' to type 'System.String'..
Is there a way to get Cast working for this, or am I stuck with ConvertAll and a delegate function?

I am having an issue where the I am trying to use some Regular Expression in a constraint. The issue is it is evaluating the Regex as a string, and throwing an error. "Cannot convert String 'd+' to long".
.MapPageRoute("Parts",
"{PartName}/{Part}/",
"~/Inventory/Default.aspx",
Nothing,
New RouteValueDictionary(New With
{.Part = "d+"}))

Is it possible to declare a variable using the text of, lets say a string, as the name?If u dont get it im looking for something like;Dim Var + string1 As PictureBox..In the code "Var" is the start of the name and "string1" is the end of it so if string1 was "Hello", the picturebox would have been named VarHello.

In VB.net I've got the following line that removes all non-alphanumeric chars from a string:
return Regex.Replace(build, "[W]", "")
I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:
return Regex.Replace(build, "[W[]_]", "")
However I'm pretty sure that this says
replace non-word or [ or ] or _
how do I negate the tests for the [] and _ chars so that it says
replace non-word and not [ and not ] and not _
Some examples:
"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"

still pretty new to programming in general, but I have most of the basics figured out.I stumbled across this problem today, though. I wanted to try making a simple encoder/decoder. However, I am having trouble getting characters from a string.
I have a list(of char) to separate the individual letters in the message (letterList), and textToConvert is the text that the user types in to be encoded. Here's the section of code my problem exists in:
For i = 0 To textToConvert.Length - 1
letterList(i) = textToConvert.Chars(i)
Next i
Upon running my program, I get an out of range exception for the middle line above. Am I doing something wrong?

I am using the EnumWindows API Call, and I've looked at an API website. It can't convert a Delegate (from AddressOf) to a Long, so I made a delegate type for it. (Uh-oh, already.) I need to know something that will take the returned IntPtr and get the window title, so I can activate it with another API call and send some keys.

Using VB.NET 2003 Asp.Net 1.1. I'm data binding to a label in a grid and need to knock off the last two chars, not so easy as I thought.
I know this is wrong it just shows how I'm coding:
Code:
<div id=CODE>Private Sub TemplateControl_DataBinding_Label(ByVal sender
As Object, ByVal e
As System.EventArgs)
Dim lc As Label
Dim sColumnName As
String = ""
[Code] .....
One problem is what I want to achieve:
I want to have:
$123.00
$15.00
$1,000.00
$123.50
$45.78
My data comes back with 4 places on the end
123.0000
15.0000
45.7800
35.9000
The $ sign I have in my code does work
so I have"
$123.0000
$15.5000
and so on.
I don't believe there will ever be a point where the last two are anything other than zeros.

I have a very long string. I need to parse this string so I can get information out of it. I know what each segment starts with and ends with. The length of the information will vary. I don't know what the easiest way of parsing this string.
Example data will be
ST*997*232898~AK1*HC*8888*~NM1*2*TESTING........
So i will want to get everything from ST to AK1then AK1 to NM1 and so on and so on.
