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 string like so
Jamie(123)
And I'm trying to just show Jamie without the brackets etc
All the names are different lengths so I was wondering if there was a simple way of replacing everything from the first bracket onwards?
Some others are displayed like this
Tom(Test(123))
Jack ((4u72))
I've got a simple replace of the bracket at the moment like this
mystring.Replace("(", "").Replace(")","")

Dim rexCR As Object
rexCR = CreateObject("VBScript.RegExp")

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.

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", "*")

sw.WriteLine(Regex.Replace(strLine, "\", Chr(13)).Replace(strLine, Chr(13), ""))

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.

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?

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.

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

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.

I'm trying to find a character in a specific character space, on a particular line, for instance:
Line 2, Charspace (or column) 75.
After I find that I would be writing a read and replace to change that character.
Can someone point me in the direction on how to specify this location?

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.

I have the problem that the DataGridView has obviously a shortcut key for SHIFT + SPACE which seems to select the row.What I would like to have is that pressing SHIFT + SPACE simply adds a space character to the current cursor position within the current cell (like for example in notepad)

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...
