Creating Modules in VB.Net, A Simple Sample for Modules

Modules are reusable codes that you can use throughout your application development.
A module can store public functions or group of functions that you can call when
needed, rather than to code it again and again, module also reduces development time 
and keeps your code area clean.

Follow the sample below to create a simple module.(The sample is a simple program
that uses module to show a message box)

Note: Please click the photos to enlarge.

Step 1. Create a new Windows Application. Then click Project in Menu Bar then under
the list click "Add Module". Please refer with the photo below.



An Add New Item Window will appear, similar to the photo next to Step 2.

Step 2. Click "Add" button to create the module. May may change the Name of your module
by typing on the module name textbox. The Default name is Module1.


The next picture shows the code view of your module


Step 2. Type the following code in the code area of your module.

Public Sub ModuleSample()
MsgBOx("This is a sample module message")
End Sub

Refer with the photo below.

Step 3. After creating the codes. Select the Form1 Design Tab and create a button.


Step 4. Now double click the button or switch to code.



Step 5. While on code view of Form1, click Module1 tab, and copy ModuleSample()

Follow the two (2) consecutive photos, for reference.



Step 6. Then switch again to Form 1 code view and paste ModuleSample()


 Step 7. Run the program (Press F5). Then click the button on Form1. You must have
a result similar to the photo below.


That's it, you got a Simple Sample on how to create a module in VB.Net. I hope you learned something today, until next time. Thank you.

Set Up AdHoc to share internet connection in Windows 7

Many are wondering if it is possible to have a WiFi even with out a router to share internet connection. Actually it is possible, you can use your laptop or your desktop computer to do the job. Just make sure that your computer has a wireless adapter. Follow the steps to configure and set it up.

Step1.Type "AdHoc" on the Search Bar. (Please refer with the photo below)


The Set up wizard window will appear.


Step2. Click Next to Proceed.

The Next window will prompt you to give your network a name and select security options.



Step3. Create A network name by typing your desired network on the text box.

Step4. Select Security type. 
              There are 3 types of security to choose from.
                - No authentication (Anyone can access your network)
                - WEP (Simple Security)
                - WPA2 (Tighter Security)

    Note: To Understand more about WEP and WPA you may refer on my post named "WEP and WPA,Whats the difference?


Step5. Set the Password. Then Click the next button in the wizard window.


Wait Until the window on the picture below appears.



Step6. Click "Turn on Internet connection sharing"
A window similar with the picute below will appear. At this moment the wizard sets up to share your internet connection.


 Then, a new window will appear that shows Internet connection sharing is enabled. It indicates that your internet connection is now being shared and your computer is now also serving as a router.

Step7. Click Close.

After the set up is done you can see your network on wireless connection list.


 NOW, enjoy your WIFI.




Ad Hoc, Creating Posibilities.

Ad Hoc, is a latin phrase that means "For This", it is a simple solution to solve a specific problem, in other words, to improvise or to have an impromptu solution.

In computer networks Ad Hoc mode enables wireless devices to connect and communicate with each other with out the use of access points or wireless routers. While on Ad Hoc mode, files, printers, other network devices or even internet connection can be shared over the network. In this case think twice before buying any wireless router, because your laptop or your desktop computer can function as a router in an instant.

WEP and WPA, What's the Difference?

You may encounter WEP and WPA once you configure or set up your wireless network at home or at your office. But what is the difference between the two.

There is a big difference between WEP and WPA, but what makes them the same is
they are both security features for your wireless network, avoiding network
intruders to access any device, files and others shared components on your network.
But what makes them different is really a different story.

WEP, Stands for Wireless Equivalent Privacy. While WPA, stands for WiFi Protected Access.
WEP and WPA uses different kinds of securitY keys. These keys are the security passwords to
connect or to access the resources shared over the networks, like internet connection, files,
and printers.


WEP
  • a security code used in some WIFI.
  • a sequence of hexadecimal digits, consisting of numbers 0-9 and letter A-F
        Samples:     1A648C9FC2 
                              96E767FAC38EK23B0C0346E15
  • Security codes must match on each device to connect with each other
  • Security codes length depends on the encryption used: 
                 40- / 64-bit WEP: 10 digit key
                 104- / 128-bit WEP: 26 digit key
                 256-bit WEP: 58 digit key

WPA

- a security policy designed to protect wireless
connection users from potential outside threats.
- WPA, WPA2 is designed with much better defenses and it has the ability to handle some wireless
threat issues.

- A WPA key is composed of 8 random numbers and letters.
Sample: 7mv9n1o

Those are brief but important differences of the two security features for wireless networks,
its up to you what protection among WEP and WPA you are going to implement over you network.
