VS 2010 Parenthesis In String?
Oct 28, 2009I'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?
Compile Error: Variable Not Defined And It Points To The Second "Environment" String, The One Inside The Parenthesis
Apr 28, 2010I 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?
VS 2010 A Custom "split" Function That Parses Out String Delimiters?
Apr 21, 2010Is this function as efficient as I can make it or can it be done more efficiently? It takes a line of text and turns it into an array of values.If the value delimiter exists inside a string delimiter, that value delimiter is incorporatedinto that value. String delimiters are removed from the values, and so is any leading or trailing white space:
Public Function ParseStringDelimiters(ByVal Line As String,
ByVal ValDelimiter As Char, _
ByVal StrDelimiter As Char) As Array

Add Custom Function To "ToString" Or Add It To Any Variable Of Type "String"?
Aug 27, 2010I am working in a form, and I had to this
Dim par1 as string = "something"
I want pass par1 to update sql statement, and I am not using AddParameter So, I had to add single quotes, the par1 will be
par1 = "'" + par1 + "'"
instead of doing the above, I was thinking in
par1 = par1.ToString.AddSingleQuote
or
par1 = par1.AddSingleQuote
Either to add "AddSingleQuote" to "ToString" method, or make it available for every variable of type "String" Can that be done?

RegEx - Pattern For Stuff In Parenthesis
Dec 17, 2009I 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

Replace Characters Inside Parenthesis Using Regex?
Sep 30, 2010To 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

Call A Function / String That It Uses Will Be Given To Function To Initiate A Download?
Aug 21, 2009Some programs implement command parameters, Like my favourite computer game - Crysis - has them and windows media player has them.But how could i implement them in VB.NET..I want to have a component of my program built as a seperate exe - so it can be an Optional component.But of course the seperate exe, on load, needs data passing to it.So i need something like Process.start("Componentname.exe", "/StartDL <Suchandsuchastring>)/StartDL will need to call a function, and the string that it uses will be given to the function to initiate a download?
View 9 RepliesVS 2008 Is Wrapping If-evaluations Inside Parenthesis Unessecary
Nov 17, 2009If 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?

String Concatenation String + Function Output + String = String + Function Output And No More?
Feb 4, 2010The following output produces a string with no closing xml tag. m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString() + "</G3Grid:Spots>"
This following code works correctly
m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString()
m_rFlight.Layout = m_rFlight.Layout + "</G3Grid:Spots>" 'add closing tag

The gvwSpots.LayoutToString() function returns a string.

.net - Create And Pass Custom Function As A Delegate?
Aug 5, 2009I have a function Process(data, f) where data is a normal parameter and f is a function needed to process the data (passed as a delegate to Process)
The signature of f is int f(a,b,c), with a, b, c supplied by Process when it calls the delegate.
Up until here, standard delegate usage.
Now, I have a special but common case where I would like to call Process with a constant f function. So I would like to write SimpleProcess(data, k) so that the caller does not need to create a delegate in this case, just pass the constant k (the only information needed).
So I need to dynamically create a constant function, g(a,b,c) which takes 3 parameters (which are ignored) and always returns k. This has to be done within the SimpleProcess function, so that I can then simply call Process(data, g) from within that function, without the need to rewrite the whole Process function for this special case.

View 1 RepliesWhy Use A Public Property Instead Of A Function To Expose A Custom Collection<T>
Jul 6, 2009During a code review I looked at set of repository classes (in vb.net). I am used to seeing these repository classes full of functions that return collections (among other things) of your domain objects. However, this repository had 1 public property and 1 private variable that looked something like this:
Private _item as Collection (of Customer)
Public Item as Collection (of Customer)
Get...
Set...
In the "Get", there is code that gets a the Customers from the DAL and loads it in the private _item. What would the benefits be in using a property (customerRepository.Item) instead of plain old function (customerRepository.GetAllCustomers)? The "Property" way looks odd to me but odd doesn't always mean wrong.
