VS 2008 Random - New Character Out Of The String And Then Remove The Character From The List Of Characters
Dec 12, 2010
[Code]...
For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

I am trying to remove a last character of a string. This last char. is a newline (system.environment.newline)
I have tried some things but I can not remove it.
Example:
myString.Remove(sFP.Length - 1)
Example 2:
myString= Replace(myString, Environment.NewLine, "", myString.Length - 1)
How I can do it?

I am trying to remove everything AFTER a specified character in a string. The string is just the Environ("username") and the local machine's IP address separated by a colon. IE username:127.0.0.1.. I have tried everything I could possibly think of in the last hour to do this with one or two lines of code and can't wrap my head around it.

Dim str as string = xxxxxxxxxxxxxxxxxxxx£xxx£xxxx**£**xxxxxxxxxxI want to remove £ in the bold which is always at certain position (11th for instance) from the end. The whole string is a long one, always change in size and can't be counted from the start. Can't use Replace as well, there may be same characters at other positions that I don't wish to remove.

I am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.

I'm trying to build a list that will be used as the in clause of a select statement. The requirement is to have the user enter a comma separated list of descriptions. Each description can contain spaces so I can't remove the spaces before splitting by comma to add the single quotes around each description. I want to remove all white space after a single quote since no description will start with a space. What's the best way to do this in VB.NET? Regular expression or a string function? Here's what I have so far.

I've been working with the substring command and after coding up all the things I needed it to do, I saw a post on here where the "For Each" statement was used basically to do the same thing.Lets say we just want to take a string apart one character at a time and add each character to a label. Which would be more efficient?I made a cheap example to show ...
Code:
ABinary = "0110 1100 0001 1011"
For x = 0 To Len(ABinary) - 1

I am trying to check if a users input contains any special characters from a list, does anyone know who I would go about doing this?
I've tried the LIKE operator:
Dim sMatch As Boolean = tTitle.Text Like "[-/,.:;*?""""<>|&'[]^%£$()_+=!#]"
but doesn't seem to work, i think special characters are used for settings.
Is there a RegEx i could use for this??

How would I check a given string for the presence of any match with a character listed in another string. I'm just looking for a binary result.
In other words, how would I write the VB.NET function called IsPresent in the following code snippet?
Result = IsPresent(AnyString, MyTestString)
For example, if MyTestString = "XYZ" then I want the following results for the given AnyString values:
MUTTON, Result = No
BUZZ, Result = Yes
HAPPY, Result = Yes
FISH, Result = No

I'm having issues with finding something in list, and removing the item, ignoring the case of characters in string.
The code goes:
Dim listItems As New List(Of String)
Dim pattern As String = "AbC"
Dim array() As String
array = {"ABC", "abc"}
listItems.AddRange(array)
Here I'd like to remove all items from listItems, that are abc, no matter what case single characters of item are, including mixed case items. So in this example, every items should be removed
listItems.Remove(listItems.Find(Function(r) r = pattern))
If I change pattern to match the case of item, then item #2 gets removed:
pattern = "abc"
listItems.Remove(listItems.Find(Function(r) r = pattern))
How can I find item in listItems, ignoring the case characters in pattern?

In a rich text box I have a lot of lines of text, all of them have the same pattern:
12345 - Something here - something else here
65474534 - stuff here - random crap here
The number of words/numbers varies from line to line. What I'm trying to do is remove the third part, so the result would be:
12345 - Something here
65474534 - stuff here
I've tried using many variations of Split(), but since the number of words varies it doesn't always split it correctly. Also It doesn't seem to go down the lines of my rich text box, and it just sticks with the first like?

I am working on a sub that essentially needs to open a text file, and replace all instances of a certain character with a unicode character. I'm trying to do this by reading the original text file byte by byte, converting it to a character, and then either adding that character to a memory stream or writing the unicode character to the memory stream. Then I'm saving the memory stream to the original file.
