Using InStr To Replace A Character From A String

Jan 21, 2011

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.

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.

I've got a simple replace of the bracket at the moment like this

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.

.net - Using Instr When String Is Nothing

Jul 29, 2009

I have the following condition

If InStr("a,b,c", stringA) > 0 OrElse (InStr("y,z", stringB) > 0 AndAlso value = 0) Then
endif

COndition 1 is false so i check for condition 2 that is "(InStr("y,z", stringB) > 0 AndAlso value = 0) "

What puzzles me is that when stringB is nothing it still falls into the if condition and executes the code.

On first look it would seem that when stringB is nothing condition2 would fail and as a result would not fall into the if condition.

Search For New Line Position In A String Variable Using InStr

Aug 7, 2009

I have an application in VB.NET which gets string data from the database. This string has data which looks as below:

"This is the update: I have an issue with the application"

I need only part of the data, that comes after the new line i.e. "I have an issue with the application".

For this I am trying to search the position using InStr where the string has data in a new line. I tried many options, but they don't work.

I used "vbCrLf", Chr(13), "
", "
", "<br/>", Environment.NewLine, but none of them work.

How can I get the data I need?

String.replace - Replace The New Format YYYY-MM-DD Back To YYYYMMDD In The Code

May 5, 2009

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.

Public
Sub Main()
Dim R1, O1, P1, C1, strDateFrom, strDateTo, strRunDate

Dec 12, 2010

[Code]...

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.

RichTextBox - How To Replace Character / Word In Text

Feb 17, 2012

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...
