I am writing a program that basically "encrypts" any text file you put into it. All of my code works perfectly, but I need to know how to replace Enter and Tab values..How do you do this?I tried doing:
s2 = s2.Replace("(Chr(10), "{123}")
But that doesn't work.
I have a function that allows a user to enter numeric vallues and also a period for the decimal points but I also want to allow for users to enter the minus sign to allow users to enter negative values . How would I go about it.
Public Function SingleDecimal(ByVal sender As System.Object, ByVal eChar As Char) As Boolean
Dim chkstr As String = "0123456789."
If chkstr.IndexOf(eChar) > -1 OrElse eChar = vbBack Then
If eChar = "." Then

How can i replace the enter key with an other set of chars

I have a program, and a string is generated. something like:
TAG POS=1 TYPE=INPUT:TEXT FORM=NAME:NoFormName ATTR=NAME:movie_imdb CONTENT= [URL]
TAG POS=1 TYPE=INPUT:TEXT FORM=NAME:NoFormName ATTR=NAME:movie_urls[] CONTENT=[URL]
Now I need this to be:
TAG POS=1 TYPE=INPUT:TEXT FORM=NAME:NoFormName ATTR=NAME:movie_imdb CONTENT=[URL]
TAG POS=1 TYPE=INPUT:TEXT FORM=NAME:NoFormName ATTR=NAME:movie_urls[] CONTENT=[URL]
v=ACFXQPGT
I know this might look easy, but I already trid so much but it doesn't work.
Now I was trying a regex:
Dim pattern As String = "CONTENT=|?http"
For Each m As Match In Regex.Matches(Data, pattern)
MsgBox(m)

But I don't know what the "|?" or pattern should be.

I am new in programming. And I am coding with VB.Net (VB2008). On my form I have 9 checkboxes. And each of this checkbox when checked is meant to submit a value to a dynamic array. Initially the array was a constant that was declared like these:
Dim Notes() AS integer = {1, 2, 5, 10, 20, 50, 100, 200, 500, 1000}
But I want the array to be dynamic. That is the user of the program is to enter the element of the array. So I decided to use checkboxes. So that if the user of the program checks any of the checkboxes, a particular value or element should be submitted into the array. And the user should be able to check as many checkboxes and have values representing those checkboxes submitted in to the array.
For example: if the user check checkbox1, checkbox2 and checkbox50.
The array should look like these. { 1, 2, 50 }
or if the user check checkbox1000, checkbox200, checkbox10 and checkbox500
Then the array should hold or contain the following integers in this order; {20, 200, 500, 1000}.
That is the array is dynamic and the content/elements of the array and the bound of the array should depend on the checkboxes that is checked. What other means can I used to enter values/elements into a dynamic array during run time.

I am currently working on a program, that you enter certain values/text in and it organises it into a word document automatically,
I found a code online, which has worked a treat, However I'm wondering what lines of code I would need to:
1. Add Bullets or Numbers
2. Add a new line of text (I can add a new paragraph but I don't want a huge space between the two lines)
3. I have around 20 check box's is there a quicker way to check which are selected then write the text in word or do I have to write alot of If Checkbox1.Checked = True then, etc)
What did I do wrong below? When I pass the enter key but for somehow the enter key event doesn't get triggered.
CODE:
The file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below. I added the two rows with .replace code in green in expecting that to be enough but it is still not working.

I am trying to think of a regex replace to replace double quotes with nothing. Example:

I am trying to filter out all unwanted characters from a string. All I want in the string is letters A-Z, numbers 0-9 as well as comma (,) plus (+) and quotes (").I figured how to do the letters and numbers, but the 3 special characters are giving me a problem. I also tried with the Chr(34) equivelant for the " sign, but no luck, as and " or , messes up the way the code is read. Here�s what I have so far, but it only works for A-Z and 0-9:
STR = System.Text.RegularExpressions.Regex.Replace(STR, "[^A-Z, 0-9, Chr(43) ]", "")
How can I specify in my string that I want to replace occurrences of ALL characters and replace them with a specified character? Something like this:
'assuming currentWord is a string that contains any word
_myWord = CurrentWord.Replace("a-z,A-Z", "*")
I am using replace function to replace a character in the file
sw.WriteLine(Regex.Replace(strLine, "\", Chr(13)))
This code is working fine, but now I want to replace two times and I want to use the replace function twice. Something like this, but it is not working . Can anyone tell me how to use Replace function multiple times?
sw.WriteLine(Regex.Replace(strLine, "\", Chr(13)).Replace(strLine, Chr(13), ""))
