ChangeServiceConfig, see ttp://www.pinvoke.net/default.aspx/advapi32.ChangeServiceConfig ManagementObject.InvokeMethod using Change as the method name. Neither seems a very "friendly" way of doing this and...

Our application is a hybrid Win32 unmanaged application and a .NET 2.0 managed application. The Win32 part is the main executable, which at some point loads and hosts the .NET 2.0 runtime and loads some managed modules to open new winforms windows.

Does anyone know how that colour is computed? Worst...
