I'm creating a hierarcy of folders where we have a standard group that have modify access on root and level 1 that is set to apply on this folder, files and subfolders.

The new folder wil get new access from a new group in AD.My chalange is to stop inheretage on the new folders on level 2 in VB.NET.

I have a VB.net applications that runs on XP and creates a directory and creates an Excell workbook and saves it. But when I do the same in Vista , when it tries to create a directory to save the excel workbook, it gives me an error that the directory does not exist. If I create the directory manually, it still gives me the same error. Is there a COM call for office 2007 on Vista other than worksheet.SaveAs(FileName:=path). All else works on Vista apart from creating a directory and Saving Excell Worksheet.

I'm trying to write an application that will allow a non-administrator user to create virtual directories in IIS6. I've tried numerous different ways of impersonating a administrative account but nothing seems to work to create the virtual directory.
Here's some of what I've tried:
dim sDirPath as string = "IIS://remotehost/W3svc/1/root"
Dim de As DirectoryEntry = New DirectoryEntry()
de.Path = sDirPath
de.AuthenticationType = AuthenticationTypes.Secure
de.Username = tbxUsername.Text

what is the correct way to impersonate another user in winforms application that will allow me to create the virtual directory without the user that's running the application being an administrator on the web server? I know this can be done, IIS manager allows you to use "connect as" checkbox to do it.
when I'm creating a new property in Visual Basic .NET in Visual Studio 2010, the rest of the Property (template?) doesn't complete the basic framework of the property in the code editor. It is now treating a statement like:
Public Property Length() As Integer
Instead of completing the property as it used to (code follows), it simply goes to the next line:
Public Property Length() As Integer
Get[code].....
What happens now is that, if I type in the 'End Property' code, the name of the property will now be highlighted as an error since it doesn't have a 'Get' or 'Set' portion.However, when I THEN type the 'Get' on the line following the 'Public Property Length() As Integer', then the balance of the property is created in the code automatically.I don't know how this got changed, but would love to change it back.Does anyone know if there's a setting in VS2010 that addresses this, or if it's something with the basic templates that visual studio uses for creating the basic code components?The weird thing is that for everything else, from class declarations, structures, functions and subs, the IDE still creates the balance of the code structure correctly. The only area where it doesn't is for Property declarations.

Alright, so I'm still working on the slot machine. I have three timers all independently going for my three "wheels" of the slot machine.
My issue, is that I'm trying to make a Stop button to stop each timer one at a time, and I'm not understanding why this code isn't working. The logic completely makes sense, and the first "wheel" stops when I click the button, however, it doesnt appear to stop the other two timers.

I have a simple application that use thread pool to read a file and input the data into a listbox. I want to be able to stop threadpool from running after clicking a stop button. How do I stop threadpool? Here is the code for my application below:

Public Class Form1
Private Delegate Sub StringDelegate(ByVal text As String)
[Code]....
I created a form and have the variable inputs for 4 motor run statements. Then with a start button the script starts and it is surrounded by a for next statement to loop 10 times. It works fine but if i need to stop the execution of the script with a stop button. I put the stop in a new section but of course does not work to do a motor stop. It just causes the exe to not respond till the loop is complete. Just need to be able to stop the Run1_Click button section.
Edit:I do not mind if it finishes the 4 motor run commands and then stops execution of the loop. So need to figure out a way to trigger a stop from a button on the form to stop the cycle. For the future the loop will be a variable integer input so 10 will not be the standard.
Edit::Does a ' Do ' statement sound like the thing to use? If so how and where would I place that? Have a Stop button on the form and it would stop after the 4th motor run command.

I have a START and STOP button and when the user clicks "start" the program does a whole bunch of calculations and all. However, I noticed that when I was testing the program I clicked STOP the program continues to execute stuff.
My START code is basically a while loop that iteratively does some calculations.
So I just put a boolean variable as the while condition and when user clicks stop its set to false and when user clicks start its set to true. However, when I click stop, the condition is set to false yes but it still executes all the code until the condition is re-evaluated right...so my question is how can I get out of the while loop when user instantly clicks "stop"?

Where has the whistle button gone? The class part of the inheritance has works because you can access it via code.
Why VB.NET (vs C#) does not "inherit" the constructors with parameters?

I'm facing a problem regarding multiple inheritance in VB.net:As far as I know VB.net does not support multiple inheritance in general but you can reach a kind of multiple inheritance by working with interfaces (using "Implements" instead of "Inherits"):
Public Class ClassName
Implements BaseInterface1, BaseInterface2
End Class
That works fine for classes but I'd like to have an interface inheriting some base interfaces. Something like that:

Now suppose I have a repository that takes an InformationReturn argument, that has to strore different fields in a DB depending on the type of Info object T is. Is it better to create different repositories each for the type T is; one repository that uses reflection to determine the type; or is there a better way using inheritance capabilities over/with generics?
I have a base class ("MyBaseClass") in a project called "BaseFramework" which is included in several solutions within the company. There are several derived class's in various projects throughout the company that inherit from "MyBaseClass". If I then create a List and add derived class's to it, it will not serialize. I realise that if I were attempting to serialize this list, and the base class and derived class were in the same project, I could simply apply the "XmlInclude" attribute to the base class and include all of the derived class's. This is however not possible across projects, because that would require a circular dependency.
