I'm trying to make a string use parenthesis ( "(" and ")" ), but for each one it returns: null (for the parenthesis).How can I get this to work? These are examples of codes I've tried so far:[code]....
And then I tried reading from text files that had those characters. Each one only returned a space.How can I get this to work?
How can i get the string within a parenthesis with a custom function? e.x. the string "GREECE (+30)" should return "+30" only
View 5 RepliesI have this code
Text1.Text = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData)
but, when I run it, it produces an error: Compile Error: Variable not defined and it points to the second "Environment" string, the one inside the parenthesis. Is there a reference that I should be enabling?
This program was written by AdamSpeight2008 and it checks for balanced braces does anyone know how to make it check the balance of other symbols for example: {} () <> [] [code]

View 5 RepliesI'm a normal user of to Visual Studio 2008 and very experienced with VS 2005. On 2008 when after I enter the parenthesis after the object method name I see an intellisense prompt with the parameter name defined on the method along with a := sign. What does := means and why does it show up? anyway it helps me a lot sometimes if I use same variable names on different service tiers. What does := means?

I have strings like:
1. Three (3) 10,000 gallons underground gasoline storage tanks.
2. Equip ID: (23-1)
I want to extract the '3' and the '23-1' and from the strings. I can rely on the first set being inside ( ) as the strings I need. The strings will be numeric characters plus the dash (anything between ( ) would be preferable.) What RegEx pattern would I use?
Here's what I have so far but it gets the first number and not the ones in ( ):
Function Extract_Stuff(ByVal LineText As String) As String
Dim myMatches As MatchCollection
Dim myRegex As New Regex("([0-9]+)")
myMatches = myRegex.Matches(LineText)
For Each successfulMatch As Match In myMatches
Return successfulMatch.Value ' should only be one match, return first
Next
Return ""
End Function
I have seen all over the internet to format a NEGATIVE double value with a parenthesis WITH a $ symbol ie. currency type.
I am looking for a .NET format string, to format
12345.67 = 12,345.67
-12345.67 = (12,345.67)
To search a pattern containing parenthesis, they must be escaped using backslashes. So to search for (Streetname) you must use (Streetname). If you don't use , whatever is between () will be retained and available for reference through the variables $1, $2 etc... Exemple, in the sentence "It's worth noting that (StreetName) can be anything...(Post), (TreeStump)", $1=StreetName, $2=Post, $3=TreeStump

If I want to do a if-statement, wich one is the most correct way?[code]Of course, both will work but to me, the second way looks more correct. I feel that it's much easier to understand what's actually going on, especially if there are several expressions to be evaluated. But my guess is that there is no difference in preformance, or am I wrong?

I have an app that calls a DLL, and passes a string to it (by reference). The DLL then fills the string and passes it back to the app. Before calling the DLL, the string must be sized correctly to fit the data the DLL is going to pass it. In the past (using VB.NET 2003) I just initialized the string with the correct number of spaces. This always seemed silly to me and I'm wondering if, in VB.NET 2010, there is a way to do this using a number to define the size?

For my ToDo list I need lots of variables to store data in.Each item of the list has 3 strings in it: Activity, start time and end time.To make multiple tasks in my ToDo list I think it's the most usefull if I use this: 'For x = 0 To 1000', so on the launch it will make 1000 variables to store my data in.But for the 3 string for extra info I need something like this:
x.a
x.b
x.c
Where x is the integer, and a, b and c are the 3 strings. If I try to do this I will need to do 'Dim a, b, c as String', but that way it will not understand x.a x.b and x.c If I do 'Dim x.a, x.b, x.c as String' it gives me an error, because x.a is not a String...
Dim a() As String = {"h", "e", "l", "o"}If a string has a character that is not listed in that array, give an error, how is it possible?
