• Differneces between static class and instance class with private constructor

  - by dotnetdev

  Hi, Although a static class has only one instance and can't be instantiated, a class with a private constructor can't be instantiated (as the constructor can't be seen), so every time you call this class, this is the same one instance? Factory classes always follow the last convention (instance class with private constructor). Why is this? Thanks

• Why does the month argument range from 0 to 11 in JavaScript's Date constructor?

  - by Agnel Kurian

  When initializing a new Date object in JavaScript using the below call, I found out that the month argument counts starting from zero. new Date(2010, 3, 1); // that's the 1st April 2010! Why does the month argument start from 0? On the other hand, the day of the month argument (last one) is a number from 1 to 31. Are there good reasons for this?

• How many registers in custom VM?

  - by DeadMG

  I'm designing a custom VM and am curious about how many registers I should use. Initially, I had 255, but I'm a little concerned about backing 255 pointers (a whole KB) on to the stack or heap every time I call a function, when most of them won't even be used. How many registers should I use?

• compact framework windows CE using ExtEscape to control the brightness

  - by mack369

  I need to be able to control brightness of my Windows CE 5.0 device. I've found that there is an API function ExtEscape to do that ( http://msdn.microsoft.com/en-us/library/aa453063 ) but it needs a structure ContrastCmdInputParm (http://msdn.microsoft.com/en-us/library/Aa447689 ) as a parameter. Since ExtEscape is unmanaged, I cannot pass a .net structure. What is the simplest way to call this function?

• What's behind the 'system' function in perl?

  - by JohnJohnGa

  i can thought that it will open a shell, execute the parameter (shell command) and return the result in a scalar. But, execute 'system' function in a perl script is faster than a shell command. It will call this command in C? If yes, what's the difference between rmdir foo and system('rmdir foo'); Thanks,

• Accessing Identity.AuthenticationType

  - by Tewr

  While implementing a custom authentication type in a wcf service, I'm trying to read the property IIdentity.AuthenticationType using the call Thread.CurrentPrincipal.Identity.AuthenticationType. Unless the account running the service is local administrator, UnauthorizedAccessException is thrown when accessing this property, much like described in this support thread. I can however reset the Thread.CurrentPrincipalobject without hassle, thus altering the Authentication Type - But read it, I cannot. Is running as an administrator the only way here or is there some trick to let the user running the service "just" access this property?

• Designing a web service to be called by another language

  - by CollegeProgrammer

  This will sound naive (but then I am a junior programmer), but if I write a web service say in Python (standard WSDL web service), I then need to host it so it is reachable from an end point. This will give a URI for the service and then from another language, say Java or VB.NET (any), I can add a web service (this one) and then call the web service's object model, correct? Thanks

• Removing Directions markers from the Google Maps API V3

  - by anonymous

  To remove a normal marker from a map, I understand you simply call marker.setMap(null), but when implementing the Google Maps directions services, it automatically adds markers A and B onto the map ( calculating directions from point A to point B ). I do not have control over these markers, so I cannot remove them in the normal way. So how can I remove these markers (I have custom markers on the map instead)?
