I'm trying to create a new thread and send multiple parameters as well as a delegate to report back. In VB8 I always hate to do this because it requires either introducing a new class/structure or a delegate. Is there any better way to do this in VB9 ? I'm looking for a solution something like this : Dim Th As New Thread(AddressO...
If I have a large amount of data in memory, what is the best way to copy it into a SQL CE table? The current technology stack is C#, ADO.net, and SQL CE. My initial idea was to do one INSERT statement for each row of data, but this is time-consuming. Is there an easier way? ...
The WinForms ProgressBar control allows its foreground color to be set. While this normally works fine, the foreground color setting seems to be ignored on XP when using the obnoxious Luna style: it is always green. Similaraly, XP Luna seems to ignore the 'Style': Although I have set it to 'Continuous', the progress bar is always drawn ...
I saw another post that suggested the following: String^ clistr = gcnew String("sample"); IntPtr p = Marshal::StringToHGlobalAnsi(clistr); char *pNewCharStr = static_cast<char*>(p.ToPointer()); Marshal::FreeHGlobal(p); I just wanted to check and see if there is any other, preferred way, or if anything was wrong with the above? ...

Pages have Roles. Users have Roles. A user may only view a page if he and it share one or more roles. This works: Dim Allow As Boolean = False CurrentPage.Roles.Load() For Each r As Role In CurrentPage.Roles r.Users.Load() For Each u As User In r.Users If u.Id = CurrentUser.Id Then Allow = True ...
I have an unmanaged C++ exe that I could call from inside my C# code directly (have the C++ code that I could make a lib) or via spawning a process and grabbing the data from the OutputStream. What are the advantages/disadvantages of the options? ...

ServiceController serviceController = new ServiceController(someService); serviceController.Stop(); serviceController.WaitForStopped(); DoSomething(); SomeService works on a sqlserver file. DoSomething() wants to copy that SQL file. If SomeService isn't closed fully it will throw an error because the database file is still locked. In t...
I need a robust, user-friendly, professional-looking .NET WinForms IP address control for use in a project I'm working on. This control, at a minimum, should support IPv4 addressing and ideally would support IPv6 addressing as well. I would prefer a free control with C# source code, but don't mind paying for one. I am using .NET 3.5 S...
I've got a PropertyGrid that reflects properties of my class. I am watching the PropertyValueChanged event and notice that PropertyValueChangedEventArgs provides the GridItem that was changed.

I have an executing assembly, which generates another assembly dynamically using AssemblyBuilder. The generated assembly consists of functions which simply test the construction of certain classes in the executing assembly. Since the functions in the generated assembly reference classes in the executing assembly, I want to have the exe...
Hi guys I have a need for an Image Library within my organization and I was wondering if anyone knows of any that they could recommend. It will need to be able to integrate with any number of our own solutions (meaning it will have a set of services or APIs that one can use for integration). Also I would be great if it had: facial reco...
First of all, let me apologize in case the title doesn't make sense. I'm having a hard time understanding what I'm doing, let alone being able to use the right words for describing what I'm doing. I'm building a generic grid class in which I define the columns by a header / linq expression combination: public class Column<T> { publ...
I am working in VB.net and have a Class, Foo, that implements an interface, IBar. I have a List of Foo's, but I need to pass a list of IBar's into a function, but I keep getting casting errors, even when I use DirectCast. My code is Class Foo Implements IBar End Class Interface IBar End Interface Sub DoIt(ByVal l As List(Of IBar...
I am trying to do some custom drawing in the row headers in a PivotGridControl in version 9.1. In version 8.2 I could use CreateDrillDownDataSource on the FieldCellViewInfo property on the event for the custom draw. In 9.1 this method does not exist. The code I was using in 8.2 looks like this. Called from the CustomDrawFieldValue e...
C#, .NET 2.0 I have an ASP.NET website in a solution, with 2 other projects (used as library references). When I build (debug or release) in Visual Studio, everything works fine. However, building with MSBuild fails. This build had been working (it's actually invoked via a nAnt task). The only thing that has changed is that I have a...
