Are you Confuse between Abstract class and interface?

If you are unable to find out, when to use abstract class and interface. Then here is the solution of your problem. I found very useful article on Abstract class and interface. The author “Rahman Mahmoodi” has explained the things in very nice way.


Before going through this article even I was not having clear picture of abstract class and interface.

But now I’m clear about abstract class and interface.

I would suggest all of you to at least once go through this article. And fold back your shelve to learn Abstract class and interface.

Link provided below.

Dynamically Find controls Type used in web application using WaTin

Introduction:
Using this WaTin feature user would be able to get all the controls types dynamically used in web page.
Details:
  
While performing automation so many times we have faced the issues to find the control type on fly and perform some basic operation or get the properties of controls.


Let me give an example to explain this with clear picture.

Suppose that developer has placed a table on webpage. This table would contents many controls like textbox, button, picture box, label, dropdown, list etc. etc. all this control would appear in table cells dynamically, it means we are not sure when and at what position of cells it will appear in table.

Now we have to read this control on fly and performed some basic operation.

So being an automation engineer, we have programmed our automation code in such a way to know about this control and where it has appeared then performed operation or read properties of that control.

Its bit tricky to handle this kind of situation.

To solve this kind of issues WaTin have provided one best feature to get the type of controls and then based on control we can call our custom method to either get the properties or performed common action.

Here I will only show to how to read controls types on FLY using WaTin.

Below is the Image of web page (to automate this scenario I have developed one basic web application)

And here is the piece of the code to the same.

try

{
IE ie = IE.AttachTo<IE>(Find.ByUrl("http://localhost:28348/Home.aspx"));
var tablecells = ie.Table("table").TableCells;
var type = new string[tablecells.Count];
int i = 0;
    foreach (TableCell tableCell in tablecells)
    {
      try
       {
          string watinType = tableCell.Elements[0].GetType().FullName;
          if (watinType != null) type[i] = watinType.Split('.')[2];
       }
       catch (Exception)
       {
           throw;
        }
    i++;
    }
}
Catch (Exception)
{
throw;
}

And below is the Result when you run the above piece of code. You can see all the controls type in the Type array of string. Shown in below drop down.
Feel free to provide your valuable comments and suggestion.

Perform action on web application using White framework

Introduction:
Using this user would be able to transfer control from WaTiN framework to White Framework to perform action on target web site which is not provided by WaTin.
you can also read this post on http://www.c-sharpcorner.com/UploadFile/jawedmd/perform-action-on-web-application-using-white-framework/

Details:
Before explain this Article/tips I assume that reader is well aware with WaTiN and White Framework (refer below link to get roll your eyes with WaTin and White framework).

Being automation engineering sometimes while automating web application we have to passes the browser control from one framework to another framework to perform some additional action/task on target application.

Okay so let's talk about some real time scenario.

To automate web application I highly concentrated on WaTin framework, as I'm good in that.But sometimes I have to pass browser control from WaTin to White (framework for Windows application) to get focus of open browser or to bring the Browser on User Focus and/or user wants to Click at some particular coordination of browser for that the white framework is much comfortable doing this.

• To know more about White you can refer my link posted on this site
    Click Here
       "or"
  http://white.codeplex.com/

• And to know more about WaTin framework you can refer below link.
   http://watin.org/

okay so now come to the coding part,To achieve this below is the piece of code doing the same?.

I have commented each lines of the code to get clear picture about logic of the code written. And I think rest of things is self-explanatory.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using WatiN.Core;
using WatiN.Core.Logging;
using WatiN.Core.Native.Windows;
using White.Core;
using White.Core.UIItems;
///
///Pass the Browser control from Watin to White
///

class BrowserFocus
{
//Instance of Internet explorer using watin
readonly IE _browser = new IE();
///
/// Method to open browser using watin
///

public void AutomationUsingWaTin()
{
//open browser
_browser.GoTo(http://jawedm.blogspot.com);
_browser.WaitForComplete();
//call white method to pass control from watin to white
PerformActionUsingWhite();

}
///
/// Perform Operation on Web application using White, by passing control from WaTin To White
///

private void PerformActionUsingWhite()
{
try
{
//Get the application from watin using processId
var app = White.Core.Application.Attach(_browser.ProcessID);
//get the open browser by watin for white
var windows = app.GetWindows();
White.Core.UIItems.WindowItems.Window window;
//check whether its having browser control or not
if (windows.Count == 1)
{
window = windows[0];
}
else
{//get the browser control using desktop instance
window = White.Core.Desktop.Instance.Windows().Find(w => w.Title.Contains(_browser.Title));
}
//bring the focus on Browser using white
window.Focus();
//Coordination of point where we want to perform right click
var point = new System.Windows.Point(400, 500);
//Right click on the browser using white.
window.RightClickAt(point);
}
catch (Exception ex)
{
// This happens when one of the open windows doea not respond.
// Logger.TraceException("White caused an exception", ex);
}
}
}

Feel Free to provide you valuable feedback and suggestion.

Assert for Image in MStest

Few days back while giving an interview in some R&D company. The interviewer who took my interview asked me one question, how will you assert images in test method and I was unable to answer this question, cuz I had never used this in my automation till now. Let me put this in clear way!!


Question: In your test method how will you assert for image. Like assert that two given images are same or equal?

Answer: I was not having clear answer to this question. Just I told that we have to customize our Assert for images assert.

Then I come back and wrote piece of code to assert the image for AreEqual.

Here is the code. Thanks to interviewer who forced me to think about this.

Test Method:


Assert Class for Image(Assert.AreEqual)

Tools To Validate Output\Get all dependencies objects From Store Procedure.


                                **********TALK 2 DB**************
I have developed an application/tool to get the output from a store procedure after connecting to the source and target storprocedure on a specific server.


Just you need to pass inputs parameter on UI and this will show all the output values generated by selected store procedure. Even you will get flexibility to get all the dependencies object names on particular selected store procedure name. These entire interfaces on UI itself.

Still i am working to come with full article or details.

Soon I will share an article with all of you.

To just give a glimpse of the application, i have added few snaps shot of tool.

"Talk2DB" that’s the name of this tool.

Resizing an Array

I have seen people declaring an array of fixed size. But sometimes while working on dynamic elements size this would be capable enough to hold all the elements in the array. But unfortunately it’s not true. Sometimes you need to handle with small set of data and sometimes with big set of data. Then, how to resize the array. So that it would be capable enough to hold this situation.

Simple:
The .NET Framework Version 2.0 introduced a solution to this problem by adding the

Array.Resize method, which is used to change the size of an array.

 Assume that, you have an array named firstArray initialized with five

Elements, you can extend its size to ten elements by using the following

statement:

Array.Resize (ref firstArray, 10);

This is very small method. but, very useful
See the example with the code below.

What ia dumb file and how to capture it.

A nice article to read about What is a dump, and how do I create one?

i found this while surfing..so thought to share with all of you!!

http://blogs.msdn.com/b/debugger/archive/2009/12/30/what-is-a-dump-and-how-do-i-create-one.aspx

Using Visual studio you can capture the Dump file also.
make sure that under Debuge the Save Dump As menu item is added in visual atudio. if not then follow the below steps to add this menu item:

a. Select Tools -> Customize

b. Select the Commands tab

c. Select Debug from the Menu bar dropdown

d. Click Add Command...

e. Select Debug from the Categories list.

f. Find the Save Dump As entry in the Commands window.

g. Click OK (the Save Dump As... command is added to the top of the Debug menu).

h. Click Close

You can use the following steps to get a mini dump file:


1. Start Visual Studio.

2. Start another instance of VS.

3. In the second instance click Tools
Attach to Process...

4. In the list of processes locate devenv.exe.

5. Click Select... and explicitly choose 'Native' and 'Managed' code.

6. Click OK and OK to close Select dialog and Attach to Process dialog.

7. Go back to the first instance of VS and repro the crash\hang.

8. Upon the crash\hang, control should go to the second instance of VS.

9. In the second instance click Debug
Save Mini Dump (without heap).

J-AXE: A File Splitter in C#

Introduction

 J-AXE file splitter is a windows application developed using C# .Net to split file in to time interval,Based on size and total files after splits. I would not ignore the fact that this is some kind of new application, Already there is so many open source project are available to achieve the same purpose. Then the question is why I have spent lots of time to develop this app: allow me to explain the question: whatever application is available as open and/or paid, you will not get the options to splits the file based on Time interval or duration. But here you will get this functionality along with other functionality with new flavor; and the main point is that I wanted to develop this using C#.Net and by developing this kind of application I will get a chance to learn something new And even I would utilize my free time into something productive .So I did this and here is the UI of this J-AXE file splitter application.
 (http://www.codeproject.com/KB/applications/JAXEFileSplitter.aspx)


                                                  Fig 1. JAXE File Splitter UI.


Might be you will think that why this application name is J-AXE? Actually the letter J came from Jawed and AXE is to cut some wooden block. So, I have chosen this application name as J-AXE.

Background

 Of course there was something which triggers me to come up with this ideas/application. Last month I recorded family videos using my camcorder after that I added few songs and effect in to recorded video to make it movies so that I can distribute this among family’s members. Now I wanted to split this file into durations instead of size so that I can make it into different parts, something like Part1 as 30 minutes and Part2 as45 Minutes. I searched here and there for open source but whatever I got all were having functionality to splits file only by size not by the time interval.

Then this requirement triggered some chemical imagination into my mind to come up with some application to fulfill my requirement and here it is an application “J-AXE: A file Splitter”.
 
Using the code

 J-AXE: A file Splitter a Windows application is very handy in use. The whole solution is divided into 2 Projects .One project would be User interface and Second Project would be nothing but our main logic which is in DLL format. The idea to separate logic from UI and make logic as DLL so, that anybody can use it easily without referring to my UI implementation.

Let me give you some pictorial presentation of the whole scenario (Class Diagram):
 
                                Fig 2. Class Diagram of JAXE File Splitter with JAXE DLL.


First I would like to explain the implementation of UI part. Then, I will explain the Logic part :

PART1: User Interface
The Block diagram would be something like this:

                                   Fig 3. Block Digaram of JAXE File Splitter.


On UI User will get below option to splits the file:
1. Based on Duration (Time duration in sec/min)
2. Size(in Bytes/KB/MB)
3. And Number of files

Based on the option selected we will call the corresponding function to splits the file:

I have already published this application on Code project., for code details and explanation you can visit the below link for the same:

Move Items from one listbox to other list box

So,here is the piece of code for that:

public static void MoveSelItems(ListBox from, ListBox to)
{
for (var i = 0; i < from.SelectedItems.Count; i++)
{
to.Items.Add(from.SelectedItems[i].ToString());
from.Items.Remove(from.SelectedItems[i]);
}
}
~jawed

Splites files using C#

Here is the code snippet to Put files under AXE to splits the particular file and then place the output files at target location.

Using System.io;
Using System;

//Method to split files
public void SplitFileBasedOnNumberOfFiles(string inputFile, int noOfFiles,string outPutLocation)

{
//Open the file in read mode

var fs = new FileStream(inputFile, FileMode.Open, FileAccess.Read);
//read the inputs for how many files user want after splitting
var numberOfFiles = Convert.ToInt32(noOfFiles);
//get the size of each file after splitting
var sizeOfEachFile = (int)Math.Ceiling((double)fs.Length / numberOfFiles);
//start the for loop to go through num of file and split that
var baseFileName = Path.GetFileNameWithoutExtension(inputFile);
var extension = Path.GetExtension(inputFile);

for (var i = 1; i <= numberOfFiles; i++)
{
//get the base name
//get the extension of the file
//get the out put location with output file name
var outputFile = new FileStream(outPutLocation + "\\" + baseFileName + "_" + i.ToString().PadLeft(5, Convert.ToChar("0")) + extension, FileMode.Create, FileAccess.Write);
var bytesRead = 0;
//array of bytes
var buffer = new byte[sizeOfEachFile];
//read the file bytes by bytes and put into output buffer
if ((bytesRead = fs.Read(buffer, 0, sizeOfEachFile))
outputFile.Write(buffer, 0, bytesRead);
outputFile.Close();
}
fs.Close();
}


Print html or any files from Windows form using C#

Using this code you would be able to print any type of pages.
just copy and paste this code on any button event handler.

private void buttonPrint_Click(object sender, EventArgs e)
{
try
{
Process printProc = new Process();

 printProc.StartInfo.FileName =" yourFileName";
printProc.StartInfo.UseShellExecute = true;
printProc.StartInfo.Verb = "print";
printProc.StartInfo.CreateNoWindow = true;
printProc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
printProc.Start();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Jawed Blog say!!", MessageBoxButtons.OK, MessageBoxIcon.Error);
}

}

C# Code snippet to send an Email with attachment from Outlook, Yahoo, HotMail, AOL and Gmail

1. Down Load Source Code click here.
Introduction
Using this code snippet user would be able to send an email with attachment through Outlook, Yahoo, AOL, HOTMAIL and Gmail.
Background
Already loads of information are available on internet for the same purpose. But not all the code is placed at one place. So here is my small effort to accumulate all the code at one place and that is nothing better than CodeProject. Hopefully it will be helpful for the beginners or whoever in needs of it.
Using the code
Name Space:

Block Diagram(SMTP Setting for various client):
Below is the Block diagram for the SMTP settings i have used to send out an email from various client providers.
Wherever needed I have explain the code in details. The codes are self explanatory, any way for the same I have included comments. So here is the code snippet to achieve your purpose.
1. Using Outlook:
To send an email using outlook, we need to add a reference to the dynamic link library for Outlook which is called Microsoft.Office.Interop.Outlook.dll.
For the same follow the below steps
1. Go to your solution explorer
2. Click on add a reference
3. Click on .Net Tab
4. Go through the DLL and select Microsoft.Office.Interop.Outlook.dll correctly.
5. When you have selected the correct reference you select the “OK” button and this reference will be added to your project under references.

6. Now we need to add a reference in our class to the Outlook reference we have added to the project in our previous example.
using Outlook = Microsoft.Office.Interop.Outlook;
And finally the code would look something like this:

2. Using HOTMAIL:
To send an email using HotMail, we need to add a reference to the dynamic link library for Hotmail/Gmail/AOL/Yahoo which is called System.Net.Mail.
For the same follow the below steps:
1. Go to solution explorer of your project
2. Select add a reference
3. Click on .Net Tab
4. Go through the DLL and select System.Net.Mail.
5. When you have selected the correct reference you select the “OK” button and this reference will be added to your project under references.
6. Now we need to add a reference in our class to the Hotmail/gmail/aol/yahoo reference we have added to the project.
using System.Net.Mail;
Note: The HOTMAIL SMTP Server requires an encrypted connection (SSL) on port 25.
And finally the code would look something like this:

3. Using Yahoo! 4. Using AOL:
5. Using Gmail:
Note:
The GMAIL SMTP Server requires an encrypted connection (SSL) on port 487.




Already I am using the above code snippet for my automation purpose and its working fine for me!!

Thank you!!

Post Comments web page in ASP.Net using C#

Recently I have developed a web application automation application in which I have added a functionality for the user to post their comments, experience and questions for the admin.
Thought to share this approach with all of you.
So here is my approach what I have done.
1. An aspx page with name URComments.aspx.
2. we will use XML file to store all the comments posted by the users.
3. Used GridView to show all the comments posted by the users.
4. On page load and/or on post button click we will call a funtion to read all the comments
posted till now by the user and show that in to GridView.
5. Below controls we will on design view of URComments.aspx.
a. Text box to get the Emailid from the user.
b. Text box for the user to entered Comments and/or suggestion.
c. Button to submit comments.
d. GridView to show all the comments posted till that time.
The web page would look something like this:

Fig 1. Web Page with Post Comments Feature

6. The XML file format would be something as below. This XML file we will use to store all the comments provided by the user. B d way you can customize this as per your requirement.


fig 2. XMl File to store Comments posted by User
Page Load :
public static string xmlPath =ConfigurationSettings.AppSettings["xmlFilePath"].ToString();
//on page load redirect the user to the specific url and then show all the comments
//posted //till //now
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
showThePostOnWebPage();
}

}

Showing Post in Web Page:
//Display the Post on webPage
public bool showThePostOnWebPage()
{
bool result = false;
try

Now you are ready with the Post Comments project.
You can integrate this with your web application to provide the user an option to share their suggestion/comments and issues with others.
Hope you would get benefited form this.

Feel free to provide your comments.

Debugging, Tracing and Instrumentation in .NET and ASP.NET (14 FAQ) by Shivprasad koirala

A nicely explained article about Debugging, Tracing and Instrumentation in .Net.
This article is posted on Code Project by Shivprasad koirala.
He has explained everything in such a nice way with nice images and videos that you will understand all the pin point of Debugging, Tracing and Instrumentation in .Net.
Let me put some contents from his post:
What is Instrumentation?
Debugging application is not just about pressing F 10 or F 11 and watching “add watch windows” using visual studio IDE. Debugging becomes pretty complex on production environments where the project is deployed in a release mode and you need to figure out till what point the code ran and when did it crash. The worst part is you are enjoying your sleep at home and suddenly someone calls up and says, “Hey! the application crashed in production”.If your application is well planned with proper instrumentation you can just say the person to view the event viewer or a log file for further details and you can give the solution on the phone itself.So defining instrumentation in short, it’s the ability of the application to monitor execution path at critical points to do debugging and measure performance.
What is debugging and tracing?
We would like to enable application instrumentation in two situations while you are doing development and while your application is in production. When you monitor application execution and performance in development stage is termed as “Debugging” and when you do in deployed environment it’s termed as ‘Tracing’.


Thanks to Shivprasad koirala for posting such a useful and knowledgeable articles.
Hats off to you!!!

Test Automation FX - UI Testing in Visual Studio

Few days back there was some requirement in my project where we have to automate windows application/desktop application developed in C#.Net. I thought to develop an automation framework for the same. But before starting of this we thought for doing some goggle might be some tool would be available to perform my task.

After searching I came across TAFX(Test Automation FX). This was a nice tool which will give you the freedom of language, recording and nice flexibility to customize the generated code after recording.


Let me put some point which I have noted down from web:
Test Automation FX (TAFX for short) enables developers and testers to record and manage user interface tests from inside Visual Studio with 100% .NET code.
You go through this official web site of TAFX:
http://www.testautomationfx.com/
Go through below link to get screen shot of Automation of Calculator using TAFX:
http://www.testautomationfx.com/index.php/screenshots

Shortly, I m planning to give a try to this tool. Will forward my finding and experience in next blog soon.
this is not an open source tool :(
Please comments with your finding also about this tool.

Send/Read an email from OUTLOOK using C#

Using this code you can send an Email from OUTLOOK and even you can Read an Email.
Here I am assuming that you have outlook installed on the machine where you are running this code.
Send an Eamil:
using Outlook = Microsoft.Office.Interop.Outlook;
public void sendEmail()
{
try
{
Outlook.Application oApp = new Outlook.Application();
Outlook.MailItem oMsg = (Outlook.MailItem)oApp.CreateItem(Outlook.OlItemType.olMailItem);
oMsg.HTMLBody =”Hello,Jawed”;
String sDisplayName = "MyAttachment";
int iPosition = (int)oMsg.Body.Length + 1;
int iAttachType = (int)Outlook.OlAttachmentType.olByValue;
Outlook.Attachment oAttach = oMsg.Attachments.Add(“C:\\testFile.jpg”, iAttachType, iPosition, sDisplayName);
oMsg.Subject = “This is my outLook email test”;
Outlook.Recipients oRecips = (Outlook.Recipients)oMsg.Recipients;
Outlook.Recipient oRecip = (Outlook.Recipient)oRecips.Add("jawed.ace@gmail.com");
oRecip.Resolve();
oMsg.Send();
oRecip = null;
oRecips = null;
oMsg = null;
oApp = null;
}
Catch(Exception ex)
{
//
}
}

Read an Email From OUTLOOK:
using Outlook = Microsoft.Office.Interop.Outlook;
public void readEmail()
{
try
{
Outlook.Application myApp = new Outlook.ApplicationClass();
Outlook.NameSpace mapiNameSpace = myApp.GetNamespace("MAPI");
Outlook.MAPIFolder myInbox = mapiNameSpace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);
//Read all the email one by one
for (int i = myInbox.Items.Count; i >=( myInbox.Items.Count-1);i--)
{
String strSubject = ((Outlook.MailItem)myInbox.Items[i]).Subject;
// Sender Email
string senderEmailid = ((Outlook.MailItem)myInbox.Items[i]).SenderEmailAddress;
string CreationTime=(( Outlook.MailItem)myInbox.Items[i]).CreationTime.ToString();

string strEmailBody=(( Outlook.MailItem)myInbox.Items[i]).Body;

string strEmailSenderName=(( Outlook.MailItem)myInbox.Items[i]).SenderName;

Console.WriteLine(“Subject: ”+strSubject);
Console.WriteLine(“sender Emailid: ”+ senderEmailid);
Console.WriteLine(“Creation Time: ”+ CreationTime);
Console.WriteLine(“Email Body: ”+ strEmailBody);

}
}

Hope this would be helpful for you!!
