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.

View 7 RepliesI 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.

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.

So, i designated 2 text boxes (one visible containing stars and another one not visible containing the word that should be guessed), and i wrote the following piece of code so that once the user presses the button any of the stars will turn to the correct letter. My question is, i found the index of "*" and removed it, and now i want to insert the corresponding char with this index (WordInLetters). How can i find what char is at index "index" in vb.net?

I am reading a csv file in VB.net and saving the line to a SQL database. At a later point in my code, the SQL line is retrieved in the application, and the Split function is used to get 'field' values. The Split is done taking comma as the separator. The application processes many other files (including excel), and the split function is used for all of them. The problem I am now facing is that one of the csv files I read, has a field value that starts with " followed by multiple values separated by a comma and ends with another ". The normal reading of the csv file results in each of those single field values is taken to be a separate value.
An example line is:
Elker,MissB,"Bus, Taxi, Train, Ferry, Parking, Toll",800253
Where there should only be separated to 4 columns, they get separated to 9 columns instead. What I want to do is replaced the commas after 'Bus' and until 'Toll' with a '?' instead. I have tried using Replace, including the overloaded one with starting position, but it ends up replacing ALL the commas in the line with '?'
Attempt 1:
If vstrLine(intStartPos) = "," Then
strRetVal = Replace(vstrLine(intStartPos), ",", "?")
end if
Where vstrLine is Elker,MissB,"Bus, Taxi, Train, Ferry, Parking, Toll",800253
and intStartPos is the first instance of a comma after the "
It returns only the '?' and not the string with 1 comma replaced by '?'
Attempt 2:
If vstrLine(intStartPos) = "," Then
strRetVal = Replace(vstrLine, ",", "?", intStartPos)
end if
It returns a string with all commas replaced with '?'

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.
View 1 RepliesI want to select a random space in a string and replace it with a word (%word%) but there is a problem. The position cannot be fixed as i want it to be inserted at a random break. Few things which iam considering :
1)break the string at a space and merge it with the word
2) find a random space and replace it with the word. I like this point and so far all i have is break the selectedtext into string array and then iterate over each line. But i don't know how to find a random string position? Any short and sweet code please?

I am using a WPF richtextbox to create a syntax highlighter for code provided in a textbox. I want to have it automatically adjust the rich textbox as I am typing, using a thread timer I reset the contents of the rich textbox. I am trying to keep the cursor where it is suppose to be. I don't loose any text characters during the parse (except line breaks).
I don't know how to keep the caret position where the user has left it in the text. It defaults to the end of the document. I attempt to store the current caret position in the text and then set it to the document after I make my changes, however the error I receive is "Cannot set CaretPosition to be outside of RichTextBox." So I set the caret position to the bottom of the document.

How can I replace character/word in text (loaded to richboxtext) but only for those which are not on the "block" list ?
Dim str As String = RichTextBox2.Text
RichTextBox3.Text = str.Replace("1"c, "A"c)
But I want add list of words which should be excluded. I thought that I can do something like :
Dim str As String = RichTextBox2.Text
If Regex.IsMatch(RichTextBox2.Text, "shows") Then
Else
RichTextBox3.Text = str.Replace("%"c, " "c)
End If
RichTextBox3.Text = str.Replace("1"c, "A"c)
Dim str2 As String = RichTextBox3.Text
RichTextBox3.Text = str2.Replace("2"c, "B"c)
But it's not working as it will just skip replace of % for whole text and I want just just exclude particular word from list from being replaced...
I'm trying to replace one character at a time in order to store its index, therefore if the replace is used all characters are changed and I cannot keep the index of all characters.
