I need some help to create a regular expression. It is a little like a search and replace, I want to replace any string that contains parentheses with a fixed editorial comment in brackets."The Prime Minister (that idiot from Scotland) made a speech today" with "The Prime Minister [edited for abuse] made a speech today".

I am trying to write a GUI for a BAT file i made for my company. This snippet of a file i have written works fine in BAT code but not VB 2010 because the parentheses is messing it up! How can i use parentheses in a text line? Here is what i am trying:
System.Console.Write("netsh interface ip set address name="Local Area Connection" static 192.168.0.11 255.255.255.0")
I have tried using ' ' but that will not work. I have to have " " around Local Area Connection in order for it to work.
I'm trying to learn LINQ to SQL. I've run into something I just don't get.Here's the LINQ program:[code]What I don't get is why there is a minus sign in the SQL before the math in the parentheses.I didn't specify that in the LINQ query.
View 6 RepliesIs there a way to define an array inside of the sub call parentheses?
Private Sub sub_name(byval sString, arrString)
sub_name("Some Text", array.{"","",""})
What I've been doing is passing a string and using a split on it to break it into an array in the Sub/Function, but I was wondering if there was a way to make the array inside the parentheses. I've looked through Google, but I'm guessing I'm not asking the right questions or it's not possible.
in VB.NET it is possible to omit parentheses when you call a parameterless function. However this can be very confusing because developers could think that a statement is accessing a property instead of a method. this could result in a performance drop if you are calling the method again and again instead of storing the result in a temp variable.is there an option in VS2008 or a compiler option to force parentheses on statements that are calling a method? and if so, would it be also possible that VS will insert missing parentheses automatically if you "format document".

Just have a list of words, such as:
gram (g)
kilogram (kg)
pound (lb)
just wondering how I would get the words within the brackets for example get the "g" in "gram (g)" and dim it as a new string. Possibly using regex?

The error is Value of type '1-dimensional array of string' cannot be converted to 'String'.
I want the Function to accept List(Of String), Array & String and similarly return List(Of String), Array & String respectively. The Function simply adds a string (month) to the input collection. I just want to use it for string, array and list with needing to think of conversions.

Basically I have a webresponse stream:dim lol as string = readstream.tostring there is a lot of information within the string but only one link starting with http: located near the end of the string - however there is no constant character point where I can start... (i.e. 38)
I want to extract the link from the string i.e. dog cat plane car [URL]..that is approximately how it looks above - words and url substituted I want to just extract [URL]..I had an idea of parsing the string from http: to the end Then after that splitting the string up again to remove the }], however it does not return anything

I have a field that I display via: String.Format({0:c},amount) This produces the string "$28.28" However, when I try to convert back to a decimal amount, I get an incorrect format exception: amount = Decimal.Parse(amount.Text, NumberStyles.Currency) I also tried it with NumberStyles.AllowCurrencySymbol with the same results. I verified that the value in amount.Text is "$28.28". Am I missing something? Shouldn't these two operations use the same currency symbol and formats?

Okay Now I only get two errors (I dont know how to solve them)
Error3Class 'BaseApp' must implement 'Sub OnCompilerError(errors() As CompilerError)' for interface 'IScriptManagerCallback'.
And
Error4Class 'ScriptManager' must implement 'Sub CompileAndExecuteFile(file As String, args() As String, callback As IScriptManagerCallback)' for interface 'IScriptManager'.
But What I would also Like to know (as well as how to fix the errors), is would the code work?
I need a regular expression that can validate that a string is an alphanumeric comma delimited string.
Examples:
123, 4A67, GGG, 767 would be valid.
12333, 78787&*, GH778 would be invalid
fghkjhfdg8797< would be invalid
This is what I have so far, but isn't quite right: ^(?=.*[a-zA-Z0-9][,]).*$
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.
So strings are reference types right? My understanding is a reference to the string in the heap is passed even when you pass the string ByVal to a method.
