View 3 RepliesI want to get a local windows user by SID: I found this code
[ADSI]("WinNT://$Env:Computername/<SID=S-1-5-18>")
[URL]
I deduced from it, I could do it in (VB) .NET with this:
Dim strURL As String = "WinNT://" + strComputerName + "/<SID=" + strSID + ">"
Dim de As DirectoryServices.DirectoryEntry = New DirectoryServices.DirectoryEntry(strURL)
de.Properties("whatever").Value.ToString()
However, this doesn't work.Anybody knows how I can do this WITHOUT looping over all users (which requires to convert from byte[] to string first, and then compare [case insensitive] a lot of strings, which makes it slow).

View 16 RepliesI have several xml namespaces that expose the same schema.
I want to use a function that dynamically accepts a namespace and applies the attributes or the properties according to the specified namespace:
Public Sub ProcessElement(element As XElement, [namespace] As XNamespace)
element.<[namespace]:Property>.Remove()
End Sub
I actually want to set the namespace resultion withing this function to the given argument.
Look at this article, he does exactly what I want, but I am sure that in VB.NET XML Literals there is a much nicer way than doing it the hardcoded way.
I know I can simply do it like this:
element.Elements([namespace] + "Property").Remove()
But I was wondering if there is a way to include namespaces in VB.NET amazing .<>, .@, ...<> language shortcuts.

I stumbled upon something i don't quite see the logic of. Let's ork with following piece of code:
For Each ds As DerivedScale In List
If ds.ScaleID = scaleId Then
ds.ScaleID = ds.ScaleID + scaleStep
[Code].....
This piece is written for 2 records to change place and change the sequence number (scaleid). The arrow indicates where the issue occurs. The item "ds" is replaced by the object 1 indexnumber higher/lower. This does however not effect that object in the List. So when i check, item ds isn't set.
However, when i look at ds.ScaleId = ds.ScaleID + scaleStep, this is reflected in the List.
So what I am wondering is: is "ds" acting like a local variable here, and can i only make changes to it's properties?

I'm writing a subneting calculator in VB.NET.I'm using the IDE SharpDevelop.Well my problem is I'm using a function to do some calculations and then to figure out the class of the IP addresses.Well I pass a variable from the subroutine, that is accessed when a button is clicked, to the function then the variable is passed back to the subroutine and then the variable is passed again to another function but when it reaches this second function it doesn't retain the value it was given in the first function.I'm not sure if I'm just passing the variable wrong or if this is how it works.I know I can make this work probably by using global variables but I'm not sure if this is proper. So my ultimate question is what is the difference between local and global variables besides just scope and should I try and use one more than the other.
