I need to define a regular expression that accepts Alphanumeric and the following special characters:
@#$%&*()-_+][';:?.,!
I've come up with:
string pattern = @"[a-zA-Z0-9@#$%&*+-_(),+':;?.,![]s\/]+$";
But this doesn't seem to be working.
I have to process a string that could include all sorts of non-standard characters and I've been asked to provide a regular expression that will match and remove all characters that are non-alphanumeric except punctuation and spaces. Is there a way to do this?
View 3 RepliesEssentially 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.

I am trying to split a data field in VB using the split function.
The data field has the following character strings"&|:"
which I need to base my split on.
Dim elements As String() = Regex.Split(dataField, "&|:")
field1 = elements(1)
field2 = elements(2)
The field1 and field2 still have a trailing "&|" chracters.How do I check if the field1 and field2 have these trailing characters? How do I delete them?PS - I have tried "&\|:" as the delimiters in the split function which did not work.
i have been trying to remove special characters. i am not able to remove many crlf in middile of the string.
View 3 RepliesI have to match string like "DAY1","DAY2","DAY3"....."DAY31" with regex in vb.net. I tried something like this - ^?DAY(0[1-9]|[12][0-9]|3[01])$ but it did not work.
The pattern should have succesfull match if the source string is either DAY1 or DAY2 or DAY3 to DAY31 like so.
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'm working in Microsoft Access attempting to concatanate the results of a query into a single string. The code looks like this:rtn = Trim(rs.Fields(0).Value) Trim$(rs.Fields(1).Value)When I display the string in a list box, I only see the value for Fields(0) I cannot see the value for Fields(1).When I run the code in debug mode, I can see the value of rtn and it contains these non-alphanumeric boxes like this:"Earth4[] Admin[]" (where [] indicates the non-alphanumeric character)What can I do to cleanup the string, remove the [] and then display in my list box?
View 8 RepliesBasically, for each character in a charArray created from the string to split, if the character is a letter, digit, or hyphen, I append it to a temporary string. When I see a split character or the last character, and the temporary string has value, I add it to the collection to return.
For i As Integer = 0 To (charArrayLength - 1)
charToInspect = CChar(charArray.GetValue(i))
If IsLetterOrDigit(charToInspect) Or charToInspect = hyphen Then

I'm trying to use a GUID to generate 6 random alphanumeric characters (just letters and number). Is there a way to change the format of a GUID before it is generated. Or must I generate the GUID in its standard format and then manipulate it.

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()
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
