MemoryStream Truncating Input - Replace All Instances Of A Certain Character With A Unicode Character?
Jul 10, 2009
I am working on a sub that essentially needs to open a text file, and replace all instances of a certain character with a unicode character. I'm trying to do this by reading the original text file byte by byte, converting it to a character, and then either adding that character to a memory stream or writing the unicode character to the memory stream. Then I'm saving the memory stream to the original file.
the coding is to 'Get input string and put its character into List, and replace the character with other.'but having problem putting each character into List and also replacing it,[code]
I have two textboxes (InputTextBox, OutputTextbox).In the InputTextBox, if I type "a" I need to display tamil letter "அ" in OutputTextBox.For the above requirements, I tried like below,
In my VB.NET application I compare words that are recorded using IPA, many of which have many diacritic marks. In one of the comparisons, I compare the words character by character. But when I iterate over the characters, the diacritic marks come out as separate characters (as I would expect since this is unicode)However, a u character is different than a u plus an accent for the purposes of this program and needs to be distinguished.
I am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.
How do I go about truncating last character off of a string. I have a page where associates enter in their bank routing number which is a 9 digit number, but I want to trunctate the last digit of the string before passing it to my SQL table. I have a Private sub I use to pass that data into my SQL Table, so I was thinking I would somehow use the RTrim or STRLen function where I am passing Routing Number below.
What exactly is Unicode character in simple to understand, no-technicalities languange? Can you give me examples? What is the opposite of unicode character(s) and example(s).
I want to insert a special character into a RichTextBox. The character is in a Medieval Latin font (Andron) which is installed on my machine.
When I open MS Word and select Andron as the font, then go to Insert Symbol, then scroll down till I find the symbol I want, I see that its Unicode value is A752, selecting it inserts it into Word OK.
Now, back to my VB2005 project: I have a RichTextBox on my form, and the Font is set to Andron. I have two buttons on the form. Behind the first button I have this simple
However, on clicking this button I get the ubiquitous square symbol, as if it cannot find that character, which is odd (to me) as the correct font is selected for the RTB, and that code is the correct code for the symbol I want.
Edit to add: I can now see that all characters up to Ascii (Decimal) 255 (which equates to Unicode 00FF) all display OK, but any value over that does not.
AM doing a letter frequency analyzer program just like this website[URL]... but i don't know the right algorithm. Of course simple looping should work if it where just english letters, but the trick is it should work with unicode letters like arabic ,chinese etc.
how do i do this? if i can get sample code in vb.net or php, or an algol,
I used the unicode character manipultation features in my code under VB.NET 2003. Will the code still work on Unicode characters that have been added to the Unicode standard since 2003? I am aware that there have been some characters added to the Unicode standard for Persian text since 2004.
How to encode string and save using vb.net code? sound don't understand, right? let's say i want to save my string(contain unicode) to file like in NOTEPAD when you write unicode and save, you have to choose encoding = Unicode in order to see the same character when you open it later. I want to do this can any one tell me(i need code to encrypt string)?
Can I compare a char array with unicode Font file?I want to display in the richtextbox what are the characters are exits & not exists in that font file?
I have a problem with unicode character, as i create a database in SQL Server 2005. I want to query from a table that criteria fields are contain unicode character i.e NVARCHAR.
e.g: SELECT * FROM tblMyTable WHERE MyField='ភាសាខ្មែរ'. But when i did like this all rows that contain Unicode Character always display. it doesn't fit to my criteria
I have a TrueType font in my PC. And there are some unicode characters in it which I want to insert it into my RichtTextBox. The CharMap in WindowsXP shows the unicode character as U+00CC and to the right, it also displays the KeyStroke as Alt+0204So, how do I insert this unicode character in RichTextBox ? Also, if I'm going to distribute this small program along with this particular font, will this end system can easily display the unicode characters ? Or do I have to set any regional settings in that PC to
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?

i have a string "David John Roplay" i need to replace first occourance of the space " " into double space " "i have used String.Replace() but it is relplacing all the spaces.
So I have software to replace string with string, it's cool but I need code which would replace any given character (for example a) with all strings from textbox.
What i am trying to do is take a character (which is going to be into a variable by user input) and search a string for this character, and save the positions of all character found and then change the same position of these characters in another string for the character that the user inputs. In other words, like a guess a word game. User tryes a guess, i search the string for that letter or number, if it's there replace it on the text box of the GUi, if not save it in another variable as a character that has been tried already, possibly an array.
Lets say I have a label with the text "_ _ _ _ _ ", some underscores. Now what if I want the program to locate the 3rd underscore and replace with something else. Is this possible? I was guessing by getting the character's position first and somehow there is a function that replaces characters by their position.
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.
