How to Browse Folders using Dot NET

Most of you may have come up with scenarios where you wish to let the user browse for a specific folder or file. This is most commonly occured when you are requested to open a specific file in Word or Power Point.
I would be using Visual Studio 2005 and DOT NET Framework 2.0

DOT NET 2.0 Framework supports several useful dialogs. In this, we will use the "FolderBrowseDialog" class for the example.

It can be very easily found in the "ToolBox" under "Dialogs" category. Simply drag and drop one on to your Form. Add a Button also for the demo.



Then, double click on the Search Button and it would take you to the Click Event of the Button.

Inside that, place the following LOC.



DialogResult result; result = folderBrowserDialog1.ShowDialog();

if (result == DialogResult.OK)
{

MessageBox.Show("Selected Path :" +folderBrowserDialog1.SelectedPath); javascript:void(0)

}




Lets analyse each of the LOC.

DOT NET uses a Class named DialogResult. It can be used to access the result of various types of Dialog Boxes.

NOTE: There are different types of Dialogs available such as "OpenFileDialog", "SaveFileDialog".

The DialogResult can be used to get the type of result entered by the user. Such as pressing the "OK" button, Pressing the "Yes" button etc.

Then we display the folderBrowserDialog1 and set its result to the DialogResult reference. Then, we check for the event which is triggered by the user. In the "if" clause, we check whether the user clicked "OK" button. In that case, we would simply display the selected path in a Message Box. We get the selected path of the folder using the folderBrowserDialog1 ' s SelectedPath property.

FolderBrowserDialog is good but has some frustrating limitations. For more functionality and flexibility, you can consider using a custom control like the FolderView (http://www.ssware.com/fldrview.htm).

Encrypt and Decrypt Images Using Java

Hi, Most of you would find it useful to Encrypt a special picture of yours such that only you can view it. By using JCE(Java Cryptography Extension) classes, this becomes very simple. As I have already done before using Java to encrypt a String is very simple. If you are new to this, please read the article which I had already posted named "Java Encryption and Decryption" at "http://ruchiram4.blogspot.com/2009/04/java-encryption-and-decryption.html" Also, you need to have a basic understanding of Java IO. If you are new, it is better to read the Sun Java tutorial on IO. Before we move on, lets recall the basic steps in Encrypting plaintext. 1. Creating an instance of "Cipher" object and setting the mode of Encryption (Eg: AES, DES) 2. Generating a key by using a KeyGenerator object. 3. Setting the mode of Cipher operation on the Cipher object. As we intent to Encrypt, we simply set it by setting a property of Cipher object by calling its "init"

Build your own Network sniffer

Image
Recently, I ve been developing a tool to monitor the Network Traffic as an assignment. Here, I wish to share my experience with all of you who are interested in building your own Sniffer. Prerequisites : Java Programming capability, Knowledge on OOP(Object Oriented Programming) basics My Environment: I used the libraries specified for Java which is widely available. I ran my application on Windows XP only. But the libraries can be easily integrated with Linux based systems. I used NetBeans 6.1 version for development activities. But any other java IDE would do In setting up the environment, first you need to download Jpcap jar found at http://sourceforge.net/projects/jpcap Once you download this, you have to add this to your NetBeans project. It can be done as follows. After adding the Jar file to the project, you need to download the WinPCap driver. It can be easily downloaded from http://www.winpcap.org/ It is required to get low level networking access regarding packets. As for

ASP Response.Write newline

Hi, all of you who have used ASP may have encountered situations where you require to write a text output to the screen. It can be easily done by using Response.Write("Hello world"); However, if you wish to append some more text to a newline, it would not work in the following ways. Response.Write("Hello world \n"); Response.Write("Good day."); The output of the above lines would be Hello world Good day. and NOT Hello world Good day. In order to overcome this, you can very simple place an html break tag inside the code. Response.Write("Hello world"); Response.Write("<br/>"); Response.Write("Good day."); The output would be the following. Hello world Good day. Cheers !!!
