Asynchronous Method Calling

During my last interview, got a question about the mentioned subject. Have decided to learn and post some code.

Definition of the Asynchronous Calling:

Executing the method Asynchronously, inother words, executing like the concept of Thread. The bottom line is inheriting the method by System.IAsyncResult and using BeginInvoke and EndInvoke to track the status of the method. Between these methods, one can check the status by IsCompleted status.

This is acomplished by Deligate keyword. Will edit this post during the time with all the example code.

Network Intrusion Detection using Supervised ML technique

Declaimer This is my initial version of the synopsis for PhD studies. There are plenty of things that i have to complete before i prepare the final version. Thus, this would be the alpha version. Due to the length of the blog post, will not be posting the entire draft. 1.Title of the thesis Network Intrusion Detection using Supervised Machine Learning Technique with Feature Selection 2.Introduction Intrusion Detection System, IDS, is a development which improve the network security and defending the information of the association. The IDS encourage the network chairman to recognize any malicious action on the network and alarms the executive to get the information made sure about by taking the appropriate activities against those attacks.

When people do some real preparation, they tend to fail due to lack of awareness at the interviewer towards interviewing techniques. Having failed in many interviews, I've learned that the interviews fail because of the following... Reflection (or) Mirroring: The interviewer tends to see self within the candidate. The interviewer starts to compare self with the candidate and evaluate. This evaluation is totally personal. The yard stick for measuring the candidature is not generalized, but influenced.   Template (or) Checklist: The interviewer has a template of a questionnaire. The interviewer measures the candidate with respect to the list of st

Keep the system active, to avoid the auto lock

Most of the corporate offices will have a policy for screen locking. While working with a long running applications at background, like the automation scripts for testing the applications, it would be difficult to maintain the unlock state of the screen. Thus, we found a technique to keep the system active with a cheating technique. Below is the powershall scripts that keeps the system active ' I am clicking on NUMLOCK for every 5 seconds to keep the system awake Set objNetwork = CreateObject("Wscript.Network")'to get user name numOfHours=inputbox("Hi " & objNetwork.UserName & ", How many hours you want me to be awake? :->") 'time variable conatins the time in hours Set WshShell = WScript.CreateObject("WScript.Shell") 'Creating an object for clicking keys from keyboard numOfMilliSecs=numOfHours*3600*1000 'converting hours to milli seconds While numOfMilliSecs>0 'runs until tym becomes zero WshShell.Send
