Why Can't Do String.Replace() On A IO.File.ReadAllText() String
Jul 11, 2009
I am using System.IO.FIle.ReadAllText() to get the contents of some template files that I created for email content. Then I want to do a Replace on certain tokens within the files so I can add dynamic content to the template.Here is the code I have, it seems to me like it should work just fine...
Dim confirmUrl As String = Request.ApplicationPath & "?v=" & reg.AuthKey
Dim text As String = IO.File.ReadAllText( _
ConfigurationManager.AppSettings("sign_up_confirm_email_text").Replace("~", _
[code].....
For some reason I cannot get the %%LINK%% and %%NAME%% Replace() calls to work properly. I checked to see if it was encoding-related, so I made each file UTF-8. And also used the forced encoding overload of ReadAllText(String, Encoding) and still no dice.

Problem: Your task is to take input from the user in string and give the following options to the user in a menu.
1- Find a String
2- Create sub-string
3- Erase a portion of a sting
4- Replace a word in the string
5- Count number of words and characters in the string without spaces.
6- Capitalize first character of each new sentence and convert the rest
of the characters to lower case.
7- Sort all the words in alphabetical order. (Use Bubble sort algorithm to perform sorting).
To perform all the above mentioned tasks you can only use pointers. Create a function to perform every task.

fso = CreateObject("Scripting.FileSystemObject")

I have to find a string in a huge text file ( ~ 50MB) and then replace it.Since it's quite huge I tend to open the file and then read line by line, and then replace the necessary line(s) (rather than "readall" the file of course).My question is how to replace the whole line?Let's say I found the line that should be replaced . I know I can create a copy file and copy all lines into there ... but I'd prefer to replace the line in the original file rather than creating a copy instance.

I have a non standard text file, ie its not delimted etc, its pretty much free flowing. What I want to do is to search for a specifc string eg. "xyz123" and then replace it with what a user types into a text box, lets call the text box and its contents "txtreplace".
I am trying to replicate a find and replace function essentially, but will need to tailor it later on down the line, but this will be a starting point.

I would like to step through each *.txt file in a given directory, open it, find and replace all, perhaps a thousand, occurances of a given string (e.g. "00/00/00"), then close and save file, and step to next one in the directory to do the same find and replace. I've been looking at filestream classes and regular expressions but don't see a clear way to do this.

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

String

I have thios code that will load a php file (text file) into a sting via streamreader then its supposed to find and replace a portion of the text and write the changes back out to the file via streamwriter. I put my code together and after running it look at the file and it's unchanged. After looking closer it appears the problem is the find & replace operation I am doing on the string. Here is my code:

if we don't mention the decoding what decoding will they use?I do not think it's System.Text.Encoding.Default. Things work well if I EXPLICITLY put System.Text.Encoding.Default but things go wrong when I live that empty.So this doesn't work well
Dim b = System.IO.File.ReadAllText("test.txt")
System.IO.File.WriteAllText("test4.txt", b)

I am reading a text file and I need to replace a few areas with new text that I marked with {0}, {1}, {2}, {3}, {4}, {5}, {6}. So I load in the text, save it to a string variable, and then use String.Replace but it's not working.
For i As Integer = 0 To 6
fileText.Replace("{" & i & "}", DisplayStudentData(i))
Next[code].....
I put all the data items into an array, then did this after loading the text file:
fileText = String.Format(fileText, dArr(0), dArr(1), dArr(2), dArr(3), dArr(4), dArr(5), dArr(6))
Is this a good way of doing it?

I have a string, lets say "((HRARNT*50)/100) + ((HRA*10)/100)"
And, i have value for HRA, HRARNT in a DGV and i want to replace it with its value to get "((5000*50)/100) + ((3500*10)/100)"
But, problem arises when it replace HRARNT with "3500RNT" as it got HRA value in DGV.
Now, i want it to first check if its prefixed or suffixed with +,-,*,/,),( then only it should replace with its subsequent value from DGV.
Though, first i tried placing HRA,HRARNT in [] and then replace, which worked fine, but users don't want to add [].
How to implement above logic?

string var1 = (string)1;
string var2 = (string)intVar; //intVar is a int value
I just want to convert all (string)XXXX to XXXX.ToString() by using some Regular expressions or some other replace methods.

I was just wondering is there an easy way to replace a line in a string where I don't know what line it will be and I don't know what will be on that line apart from the first three characters which will always be:
To:
And that shouldnt be anywhere else in the string.
This string will be the contents of an email (read in via an EML file) I then need to change the line that says 'To: <someones@email.address> to a series of addresses then save them eml again.
I have read then entire email in and stored it in a string and can save again just struggling on the replacement of that line.
