Have you ever imagine someone
making a complete database application in 10 minutes or less, believe me it is
possible to do that and there is hundreds of videos posted in YouTube showing
people do such thing. For a geek or computer pioneer YouTube can be the biggest
source of knowledge and alternative to solutions for the problems you are
facing during development and deployment of applications.
The major
difference between YouTube and the video tutorials we purchase or download for
free online is that you tube is time saving and you can go directly to the problem
that you are facing at that exact time. You don’t have to scroll through
directories or forward and rewinding videos to find a particular solution for
your problems.
For
example consider I want to develop database application using Derby database which available in NetBeans and I have no knowledge at all
in linking database to the front end interface of java all I have to do is to
type in you tube search engine ‘database
applications in Netbeans using Derby’ .Several video will pop up
showing minimum two to three ways to
approach the problem that I have mentioned and some videos will elaborate more
in details and when you look at the comments bellow the videos you will see
people explaining about their experience and the challenge they face trying to
achieve the task you have mentioned. This will help you to realize your mistake
and to rectify them quickly and it will give you the most effective and easiest
ways to tackle the challenge you are facing.
Believe
all most every beautiful trick I do in most of the software and applications I develop
whether is inserting alarm or
creating advanced login system I learnt
in YouTube from may be a small time developer in Jamaica who have decided to portray
his skills online. The solution provided by these particular video they are
time saving and go directly to the problem that you are facing at that exact
time.
For
example one time I wanted to create advanced
system management tool. A tool that will help a user to display ‘calculator’, ‘notepad’, ‘disk management’
and shutdown graphical user interface I knew one thing to manage those tools in
windows in the easiest way was by using windows command prompt keywords such as
[calc], [write], [diskpart] and
others but I didn’t know how would I be able to link the Visual Basic statement
with these command prompt keywords for more efficient output which is free from
errors. After days of suffering to link the two believe me the solution was
simple and I was about to cry for being a fool all this time, a five letters
keyword ‘shell’ was the only thing I need
to do that. For more details on what am talking about watch this video and
experience yourself the power of you tube for developers and people who want to
attain solutions for their problems fast.
Challenge: Try To test these codes in Visual studio by developing a small System management Application:
Private Sub Command1_Click()
Shell ("taskmgr")
End Sub
Private Sub Command2_Click()
Shell ("shutdown/i")
End Sub
Private Sub Command3_Click()
Shell ("write")
End Sub
Private Sub Command4_Click()
Shell ("shutown/r")
End Sub
Shell ("taskmgr")
End Sub
Private Sub Command2_Click()
Shell ("shutdown/i")
End Sub
Private Sub Command3_Click()
Shell ("write")
End Sub
Private Sub Command4_Click()
Shell ("shutown/r")
End Sub
Results: It should be able to display Task Manager, Shutdown interface, writepad and restart the system best of luck!!!
