问题 Duplicate of: How to protect dlls? I'd like to protect my C# DLL from being used by third party applications. I'd like only MY applycation to use this DLL. How can I achieved that ? Thank you. 回答1: This is simply not possible. The whole code access security system is based upon the notion that security decisions come from the user running the code , not from the author of the code . You, the code author, do not get to tell your users what their security decisions are; you are the user's

问题 Basically I am working on FFT analysis of AC current signal with reference to AC voltage signal. You can imagine it in a phasor diagram with V at x-axis (ideally at all times) and I being the changing variable with respect to V. In a power system, the AC current (magnitude and phase) change depends on the loading system. For now, I am working with Python-generated signals only. Just trying to set up the software system before proceeding with real-time signals. So, as a start, I generate two

问题 I have a script that automatically protects a range of past Dates in my Sheet. I use the standard sheet.getProtections(SpreadsheetApp.ProtectionType.RANGE); It worked fine for several months but it has not worked since yesterday. Is there any modifications on the implementations ?

问题 I'm working on a web service that would use an SMS gateway to receive instructions from customers. Since this would be a commercial product I would like to implement a safeguard to protect our system from SMS spoofs. I don't want people impersonating others by spoofing their number. I've noticed that Twitter allows people to tweet through text messages, how can they make sure that messages are actually genuine? Is this possible, and if so how do I accomplish this? Or should I ignore this and
