Most Concise String.Replace To Mask A Password?
May 9, 2012
Let's say I have the following string:"/encryption:aes128 /password:<PASSWORDHERE> /log:log.txt"
I need to write this to a log file but the password needs to be masked (replaced with asterisks for example).I can do this easily with String.IndexOf and String.Replace in a few lines of code but I'm interested in seeing how others would implement this so that the code is as short and concise as possible. A one line replace function would be best.
My goal here is to see/learn some new techniques of combining string functions.
Note that I am not interested in using a RegEx.

What is the best way to checkt o see if the TelephoneNumber property has some string in it that does not Trim down to an empty string? I hate to use the Trim VB.NET function on Nothing just to give me an empty string whenever the TelephoneNumber is Nothing. [code] What puzzles me is that the "IsNullOrEmpty" function works as an extension method of a string instance even if the String is NOTHING. Why does this extension method work but the follow straight - .NET code raise an exception? [code]

I have a need to apply a mask to a string programmatically and not through any type of Masked Edit Control. So for example a mask of (###) ###-#### would need to be applied to a string such as 5551234567 to create (555) 123-4567.

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

In my attempts to understand vb.NET, one of the problems I have encountered is that I have not been able to find a concise definition anywhere for the Paint Event. So after many hours of researching and forum posts (and my own personal tests), here is my own definition (but it seems to fail in one instance, mentioned after the definition). I would like to create a final definition based on everyone's input, but keep in mind, the idea here is to STAY CONCISE. So here goes:
Explanation of the Paint Event
Whenever any portion of a control is UNCOVERED (except by the mouse pointer), the paint event fires. Covering of the control does not fire the event, because the covered area is not visible to the user, and is therefore irrelevant. The paint event is a messenger that alerts the program, via message, that some portion of the control has been uncovered and this message launches an OPTIONAL paint event handler (paint event procedure) written by the programmer, if one is needed to handle those situations when the event occurs. One possible situation is the most obvious...the need to redraw the uncovered region. A paint event procedure is the programmer's counterpart to vb6's automatic property, "AutoRedraw". But whereas vb6's solution was a simple and automatic redraw of the control, vb.NET's equivalent requires the programmer to define explicitly how the event is to be handled, whether it be a simple redraw or something more elaborate. This puts this event in a special category; it is not a user-desired event fired by some user-desired action...it is an internally generated event that acts more as a housekeeping "watchdog" to alert the program that housekeeping chores may have to be implemented because the user did something that was NOT DIRECTLY RELATED to a desired action. For example, when the user moves a window over a control in such a manner that a portion of the control is covered, then uncovered, this causes the state of the control to change even though the user did not specifically request it. It nonetheless may have to be dealt with, and this is managed via the paint event handler procedure.
The problem I have with this definition of mine, is that if the above is true, then why does the mouse moving across the control NOT cause the paint event to fire? After all, it is causing areas of the control to be covered and then uncovered. Is it because the mouse is a special case where the system puts the mouse pointer on a separate layer above the screen graphics, in order to prevent constant paint event messaging?

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.

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 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.

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?

I just converted a VB.net solution into C# solution. But lots of variables have been coverted like:
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.

i need to replace the whole word from a string.
for example. String= "Hi VBFriends, I am learning VB 2010."
i need to replace only VB as C#.
if i put String.Replace, its changing as "Hi C#Friends,I am learning C# 2010."
i used regex, Word boundary but not worked, below my code.
Dim sHTMLStream As String = "Hi VBFriends, I am learning VB 2010."
Dim oColl As MatchCollection = Regex.Matches("sHTMLStream", "\bvb", RegexOptions.IgnoreCase)
For Each sTemp As Match In oColl
MessageBox.Show(sTemp.Value)

I have following code snippet that is supposed to replace the existing text in a local text file but instead it's just appending the new values on top of the file and pushes the older text down.
Here is the code:
dim sr as streamreader = file.opentext(path)
dim contents as string = sr.Readtoend()
sr.close()
Dim sw as streamwriter = file.Createtext(Path)
sw.Write(contents.replace("old value1", "new value")
sw.Write(contents.replace("old value2", string.empty)
sw.close()
What do I need to change to make it replace existing text rather than append?

Update 1 This is the original string: This is what it looks like after my VB code: As you can see, the http: part is added, however the backslashes haven't been touched. Update 2 It has something to do with the slashes. Because when I replace other characters (for example a with @), then the replaced string is shown correctly. But not the slashes
