String.Replace Not Replacing?
Sep 7, 2011
I have an issue, i have a program im working on, that i have been working on and im trying to replace a whole block of text. I do it in one spot in my code and it works great, but in a different part of my code, even though im using the same exact logic and pretty much the same code (other than slight variable changes) it will not work, and i have no idea why, it just like ignores it. I took some screenshots:If you look hard the only difference is the "S12000" (top pic) is changed to "S6000" (bottom pic). The pic shows this part about 3/4 of the way thru it.

In c programming language,
I can do
printf("%d
", value);
But in c#, how can I do it? For example string is "Good %s everybody"
I want to replace %s with the variable. Are there any solution except str.Replace("%s","good morning");

I'm using a recommended character replace regex I got from this forum, however it is not fully working in deleting unspecified characters
Original String:acAc10[]() _~!#$%^'&*()+-[]`"
Actual Result:acAc10()_#$%'&*()+-"
Desired Result:acAc10() _!'-"

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.

earlier with my program question and found out that """" is how you make " become another variable in the function:Robert = Replace(Robert.ToLower, """", "A")So now I am also trying to work with other keys like the semi-colon. I put it in the function like this:Robert = Replace(Robert.ToLower, "char(59)", "B")I also tried to insert ; in place of char(59) with in front of it as an escape key, none of this worked. It still just gives me a ; when I type

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.

I've got an issue with a program I am writing. The specific issue is replacing characters in a parent string by finding, and matching, specific characters within it that are parsed from an external xml file. It's for a chat-like client.Here's the 2 classes I am using to pull the emote strings, titles, and id from external XML:
Imports System.Text.RegularExpressions

how to replace a string in a datagridview with another string?
e.g I have a column which has texts "Text1","Text2" that repeate many times in the column. How can I search-replace "Text1" with "anothertext1" and "Text2" with "anothertext2"?
I searched in datagridview members but I didn't find how to do it.

I am trimming some strings but I am unable to do anything about the strings containing plus signs. For example if I have this string with a telephone number
Dim str As String = "+46765124246"
And try
str.replace("+46", "0")
Nothing changes in the string.

i have an array that contains a-z.When i enter text like "ab" into a textbox and click the button, it will search the array and replace the text accordingly to the index number of the array and rewrite into the textbox with the index number.
But what i got from the code below is "ab0 1".May i know how to do so that the textbox will only display the index number and not with the letters. Also, how do i search the array from index 12 onwards to the end of the array.
For Each b As String In TextBox2.Text
If abc.Contains(b) Then
Dim ab As Integer = Array.IndexOf(abc, b)

Below is the section I'm having trouble with at the moment:
Friend Sub glbHooks_KeyPress(ByVal sender As Object, ByVal e As KeyPressEventArgs) Handles glbHooks.KeyPress
newStr = newStr & LCase(e.KeyChar)

Neither of these worked, though the 2nd one would clean up my code a bit. Unfortunately I'm getting an "Expression expected" error on that "newStr = If..." line. I know there's supposed to be a "Then" somewhere along it but I don't know where it's supposed to be and the poster hasn't gotten back to me on that yet.

What I basically have is a small game which I want to count wins/loss/ties. I have no problem with the game aspect but need to know how I can replace a string in a csv file. IE: If Jim wins the game, his 5 needs to be turned to a 6. After googling quite a while I came across the replace() function, but it doesn't actually rewrite it back to the text file

The issue I have, is if I try to use any sort of IO function after this (WriteAllLines, streamwriter, etc) - I get a process is being used and can't touch the file (because its being read).Must I somehow create a new file with a copy of everything including the replaced string?

I am wondering how to replace two variables in a query from selections that the user makes. One variable is chosen by a combo box called cboYEARMONTH and the other is selected from a list view called employeeListView. I know that I can use .replace to insert the YearMonth into the string but, how do I also replace the EmployeeID in the query string?

I'm using the Oracle command dbms_output.get_line to retrieve output from a stored procedure. Once my code runs the command, I'm retrieving the results through a buffer string, 32000 bytes long.Inevitably, this string will have Oracle line breaks (chr(10) and chr(13)) in it that I'd like to replace with Environment.NewLine so I can display the output in a standard Winforms textbox.Here is the code I've been using - I don't recall exactly where I got the Oracle command right now, but if I find it, I'll add the link.
Dim cmdGetOutput As New OracleCommand("declare " & _

I can replace one parameter with one value using string.replace, but how would I continue to process the rest of the string? Would I replace the first parameter then reevaluate the string again to find another parameter until no more parameters are found?
