I'm working on a form in which strings of text are being imported. A lot of these strings contain special characters, like �, �, �, &, �, etc...
When I convert these strings to text, so they can be shown as labels, the special characters either disappear (like the '&' sign) or they are shown as some sort of icons. How can I let VB handle these strings, so the special characters are shown the way they should, without having to change the (many hundreds) original strings of text?

I've got a program that in a nutshell reads values from a SQL database and writes them to a tab-delimited text file.The issue is that some of the values in the database have special characters (TM, dash, ellipsis, etc.) When written to the text file, the formatting is lost and they come across as junk "â„¢ or â€" etc"
When the value is viewed in the immediate window, before it is written to the txt file, everything looks fine. My guess is that this is an issue of encoding. But, I'm not real sure how to proceed, where to look, or what to look for.Is this ASCII or UTF-8? If it's one of those how do I correct it before it's written to the text file.Here's how I build the text file (where feedStr is a StringBuilder)
objReader = New StreamWriter(filePath)
objReader.Write(feedStr)
objReader.Close()

Essentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.
This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.

TextBox1.Text.Substring(TextBox1.Text.Length - 25, 25)Ok, Hello today i am trying to remove the last 25 Characters in my string.
I have done it before but have not used Substring() Method in a bit.
I have two textboxes. I type in one of them and the text gets copied in real time into another textbox. There is one catch. I need to replace specific character with something else.
If I enter a quote " in textbox1, it has to be replaced with " in textbox2.
I started with something like the below code, but obviously this does not work (tried different stuff - this is for demonstration only). In the example below 'a' represents " , and 'b' represents "
Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.KeyUp
TextBox2.Text = TextBox1.Text

I have a notify icon and I use the 'Text' property instead of 'BallonTipText' because I just like it better and it fits well with my application. The only thing wrong with that is the 64 character limit. How can I determine the length of a string, remove all characters after the 61st character, then add three periods at the end of the new string? I've looked around and can't find any solution to removing all characters after the first X characters.
View 4 RepliesI am retrieving string values from a table and then encode each term to make a httpwebrequest to an api. It works fine and the terms allow for foreign characters like japanese/arabic/chinese etc and these are inserted fine. The problem occurs when some of these terms contain weird characters and that is when the request is bad. The only reason it is bad xml and the template I follow gets invalid are when these characters are present. I use the
system.securityelement.escape
And also
httputility.htmlencode
As part of my cleanup. One of the weird characters ends up appearing as a space but it is not since the trim(term) does not work and when I look at the xml in visual studio it looks like an ' &' with arrow pointing up attached to it. It does not appear after I pasted it here.It appears as a line feed or carriage return and I have tried to remove that too. Anyway is there some way I can ensure that these sort of characters are removed and if I were to use the binary values like <32 invalid, will foreign characters then get excluded.
temp = temp.replace(vbCr, "")
temp = temp.replace(vbLf, "")
temp = SecurityElement.Escape(temp)

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?

buildLetter.Append("</head>").AppendLine();
buildLetter.Append("").AppendLine();
buildLetter.Append("<style type="text/css">").AppendLine();
Assume the above contents resides in a file. I want to write a snippet that removes any line which has empty string "" and put escape character before the middle quotations. The final output would be:
buildLetter.Append("</head>").AppendLine();
buildLetter.Append("<style type="text/css">").AppendLine();
The outer " .... " is not considered special chars. The special chars may be single quotation or double quotation. I could run it via find and replace feature of Visual Studio. However, in my case I want it to be written in c# or VB.NET
