Regex - .NET: Manipulating TextBox Input: Dash Every 5 Characters And Removing Special Characters?

Dec 21, 2011

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.

Replacing Characters In Textbox (including Special Characters)

Aug 5, 2011

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

Asp.net - Fix Special Characters In String?

Aug 3, 2010

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()

C# - How To Put Escape Before Special Characters

Aug 15, 2010

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

Block All Special Characters Entered In A Text Box?

I have a text box where users will enter 4 digits that are ONLY numbers 0-9. I have blocked all letters and less than 4 or greater than 4 digits. But, for example if I enter 10.0, it will throw an exception, due to incorrect math used later in the prog. So how can I block the use of a (.) or any special character for that matter! I am using specific msgboxes to let the user know what isn't allowed, and would like to do the same for special characters.

What I have so far:

If Val(txtEntered.Text) < 0 Or
(IsNumeric(txtEntered.Text) = False) Then

I have the same problem when the character is read correctly, with streamwriter output to a textfile. Word cannot read the textfile and ask to define which type of coding should be used.

MSWord Special Characters When Viewing .docx As .txt

May 1, 2012

I am writing an encryption program to become more familiar with MVB (2010). What it does is take each character in a file, convert it into ASCII, perform calculations on the ASCII value and then write to a file. (I change the extension from .docx to .txt, encrypt, decrypt, change extension from .txt to .docx)

The issue that I get is when taking the file from the encrypted state to the original. When I look at the before and after .txt values, they do not match up (I have tested the program on standard text with no issues). After doing a little looking, it seems that the special characters that show up when converting .docx to .txt are not all ASCII characters. Does anyone know anything about this, where to find information about the characters, or anything else?

Even I tried to see if the output was usable but it sees it as multiple chars, when it is only 1, and I can't find a link between what it sends and what the character is, so I can't just tell it based on whats sent what the char is, because I see no relation, I would have to type it out for each and every special character.
