How do I write an expression to calculate all characters of each row by my own defined value to each character = all the A and B and C and etc. will be as 2 and all I and J and whatever ... will be 1 so I need an end result of the total.

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.
So I have an ASP.Net (vb.net) application. It has a textbox and the user is pasting text from Microsoft Word into it. So things like the long dash (charcode 150) are coming through as input. Other examples would be the smart quotes or accented characters. In my app I'm encoding them in xml and passing that to the database as an xml parameter to a sql stored procedure. It gets inserted in the database just as the user entered it.
The problem is the app that reads this data doesn't like these characters. So I need to translate them into the lower ascii (7bit I think) character set. How do I do that? How do I determine what encoding they are in so I can do something like the following. And would just requesting the ASCII equivalent translate them intelligently or do I have to write some code for that?
Also maybe it might be easier to solve this problem in the web page to begin with. When you copy the selection of characters from Word it puts several formats in the clipboard. The straight text one is the one I want. Is there a way to have the html textbox get that text when the user pastes into it? Do I have to set the encoding of the web page somehow?

Program works good, it is mixing characters good, but it doesn't write text to the file. It will write text in console, but not in file. Note: Program is working only with words that are divisible by 2, but it's not a problem. Also, it does not return any error message.

I want to explicitly inform my user that they are not allowed to use any characters from the extended ascii character set (128-255). When I try to create a string of these values using the following [Code] It outputs them fine, with the exception of a bunch of blanks in certain areas(I am assuming these characters are unprintable), but I noticed that when I hover over the value of sVal in the VS, the tooltip/quickview of the value is written nicely on one line. Any ideas how to remove characters that would appear to be blank spaces (unprintable) when outputting this list?
View 4 RepliesI want to user to enter only numbers and characters in textbox i.e no special charaters.I don't want to use key press event of textbox.As i need same validation in gridview.
So i want to validate whole string.
My homework assignment is to create a project where a user enters a password that must be at least 3 characters long with at least 1 number and 1 alphabet character. After that the password has to be encrypted so that vowels become X, numbers Z, and it reverses. For example, a password of CS2301 would be ZZZZSC. There's supposed to be Loops to extract 1 number/letter at a time and search for them in the string to validate, and I don't know what to do. The form itself has a Text Box to enter a password and a label to display the new one, and a Go button.
This is what my code looks like so far.
Option Strict On
Option Explicit On
Public Class Form1

Retrieving strings from a serial port with ReadLine works fine as long as the line ends with a linefeed chr$(10).However if no more strings are available to be read, Do Loop or For Next hang up waiting for the linefeed which never occurs.I believe using chr$(0) in place of linefeed would still work with strings ending with a linefeed..Just that the linefeed would be output.I have the complete MSDN Library.

View 1 RepliesI have all-one-case strings representing postal addresses stored in a database, but I want to capitalize US state abbreviations (e.g. " ca " to " CA ") when the abbreviation is separated from the rest of the string by a space on either side.The lousy way I could do it would be to have 50 statements like
If addressString.Contains(" al ") Then addressString.Replace(" al ", " AL ")
If addressString.Contains(" ak ") Then addressString.Replace(" ak ", " AK ")

Edit: That is a really lousy way! Here's what I did instead:
addressString = StrConv(addressString, VbStrConv.ProperCase)
'This needed to be done anyway, but it turns " ak " into " Ak ".

I am trying to do this but it doesn't work:
VB
Dim str As String = "07" & GetBetween("Stephen 0761234567", "07", vbNewLine)Dim op As String = "lol" TextBox1.Text.Replace(str, op)
GetBetween is just a function to match something between something else. That works fine, the string (str) sets as 0761234567 just like I want but when i try to replace the text it doesn't work.

View 1 RepliesI need to be able to add (specific) special characters to text boxes. Problem is, there are five of them spread across two forms and three tabpages. What I'd like to do is bring up a form when the user presses something like "F2" while the text boxes are focused, then on that form would be a grid of buttons. When the user pushes a button, the character is added to the box. How do I get this form to reference the box that called it without passing a global variable or calling a public function? I tried Form3.Parent.Name, but that always seems to refer to nothing. Also, once this is done how can I get it to just insert a character where the cursor on the calling box is? It probably shouldn't even be on a form either since that will take the focus when it's called (which I don't want)

View 4 RepliesIn DGV, if the contents of the cell is truncated, the DGV shows ellipses (three dots) (...); but as the font is set to a Gujarati font, it displays a Gujarati alphabet "ઈઈઈ" instead of "..." because the Gujarati character "ઈ" is coded with the English "."

Then I'm saving the memory stream to the original file.
