问题 If I open a Form named FormX that does some processing on its public (not static) variable "Var". "Var" is set from a calling form and processed and returned for output. I open it from multiple forms multiple times during execution. All forms are running simultaneously. It works fine because each FormX is opened using a seperate instance of an object from its parent form. But I have a public static class "Abc" in my project which is accessible to all forms and if I add a code: public static

问题 I work for a MSSP and a lot of the security alerts we deal with, especially with new clients, can be dealt with according to some simple if-then logic without taking up analyst time to research. To handle these sorts of alerts, I am building a basic python program with a series of logic tests to see if a given alert falls into a 'known' category and can be dealt with automatically. My desired format is to have a separate python file for each client we service for organizational purposes, and

问题 I have a number of data classes, which share an abstract base class so i can work with them generically (sort of). They each have a static method called Lerp, which i use frequently along with a couple of other lines. I wanted to refactor this out into a method because of DRY,but it seems there's no way to do so. How do i get around this? Can provide code if neccessary. The code is basically this: XmlNode mineDataMin = mineDataMaster.SelectSingleNode("DataMinimum"); XmlNode mineDataMax =

问题 I've caused myself some headaches over the past couple of weeks with the curiously recurring template pattern. Following on from these two questions of mine: What’s the correct way of retrieving my custom enumeration classes by their value? Why are my static objects not being instantiated when first access to the static class is a static method on the base class? How can I improve the following example: public class DocketType : Enumeration<DocketType, int, string> { public static DocketType
