Step through the code, and you'll find that none of your if conditions are matched, so the price field is never updated.
You need to debug your code. I can't do that for you.

Why did you put those if statements in the constructor of the Form? They will only ever run once, when the form instance is created. If seems those statements need to be put somewhere else.
Also, you don't seem to have a grasp of the basics of C# or debugging techniques. True?

Yes you are right. I'm beginner, I self study at home(1 month so far) and this little application I am doing for my self study. Please help where should I give that "if section". Images of program here: http://i.imgur.com/7ncQt2m.png http://i.imgur.com/1XNUPeh.png

Somewhere where it makes sense in your business rules. The constructor isn't it.
When do you want these statements to execute? If it's triggered by the click of a button, there's a big hint right there.

You check the "SelectedIndices" in the constructor of the form. The constructor gets executed once at the very start of showing the form - and then never again. At that point you couldn't possibly have changed the selections of the controls Material and Thickness. And after you have changed the selections they're never checked again. You need to move the if-checks to a "better" place that fits the (presumed) requirement that they're executed each time you click the calculate-button.
You might also want to take a look at ComboBox.SelectedIndex Property (System.Windows.Forms)[^]
(assuming Material and Thickness are of type System.Windows.Forms.ComboBox)

I created a RESTful WCF Service and made sure that the data returned from it is of type JSON by setting its ResponseFormat property equal to WebMessageFormat.Json in my WCF Service as follows:
ResponseFormat = WebMessageFormat.Json
I checked to ensure that data returned from the WCF Service is indeed JSON by using Fiddler.
What I don't understand is if the return type of the data is JSON then why do I need to convert it to a JSON string using JSON.stringify() in my jQuery AJAX call.

First of all, you did not share the output response of the service, and we have no idea what is going wrong there. Many things can go wrong, such as the C# code might be deserializing the JSON to an object and providing you with that object.
Also, the only purpose of JSON.stringify is to serialize the objects, if you are going to render the objects or their properties on the screen, there is no need to serialize the object at all. It would be a good idea to see the output of this,
success: function (response) {
alert(response);
}
This will either show [object Object], or some valid JSON document. That will give you an idea of the type of data that is being passed here.

Thank you so much for your reply. I can now see that the data I received from the AJAX call is indeed JSON.

increment a file path if already exists using mediafire,conversion options and mega data while saving a video in c#
here is my code
try
{
String path = open.FileName;
var inputFile = new MediaFile { Filename = path };
using (var engine = new Engine())
{
engine.GetMetadata(inputFile);
do
{
newLocation = "C:\\Users\\" + server + "\\Videos\\Matchbox\\keeper starts(" + filecount.ToString() + ").mp4";
filecount++;
if (!exists)
{
System.IO.Directory.CreateDirectory(folderLocation);
MessageBox.Show("Folder doesn't exist, Matchbox folder created!!");
}
var outputFile = new MediaFile { Filename = newLocation };
var options = new MediaToolkit.Options.ConversionOptions();
Difference = outTime - inTime;
options.CutMedia(TimeSpan.FromSeconds(inTime), TimeSpan.FromSeconds(Difference));
string message = "Please wait a few minutes while converting a file";
string title = "Warning!!!";
MessageBoxButtons buttons = MessageBoxButtons.OK;
DialogResult = MessageBox.Show(message, title, buttons);
engine.Convert(inputFile, outputFile, options);
MessageBox.Show("Success");
} while (File.Exists(newLocation));
// inTime = outTime = Difference = 0;
}
}
catch (Exception ex)
{
MessageBox.Show("" + ex.ToString());
}

Was there a question in there somewhere?

"C#" is not a good subject-line; all the posts in this forum are about C#.
newLocation = "C:\\Users\\" + server + "\\Videos Sorry, that is not a server, but a user.
..if I understand you correctly, you want to convert the next file in that folder? Get a list of files, and loop through those.

And you have a question ? a problem ?
We do not do your HomeWork.
HomeWork is not set to test your skills at begging other people to do your work, it is set to make you think and to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.
Any failure of you will help your teacher spot your weaknesses and set remedial actions.
So, give it a try, reread your lessons and start working. If you are stuck on a specific problem, show your code and explain this exact problem, we might help.
As programmer, your job is to create algorithms that solve specific problems and you can't rely on someone else to eternally do it for you, so there is a time where you will have to learn how to. And the sooner, the better.
When you just ask for the solution, it is like trying to learn to drive a car by having someone else training.
Creating an algorithm is basically finding the maths and make necessary adaptation to fit your actual problem.

I would encourage to use Path class for any path related coding in C#
"C:\\Users\\" + server + "\\Videos\\Matchbox\\keeper starts(" + filecount.ToString() + ").mp4";

I am developing an English vocabulary related project. Is there any open source service available, where I can consume that to get the meanings for words.

What does this have to do with C#?
I'd suggest you post it as a QA question: [^] where it will reach a wider audience.

I need C# supported service. So that's why I asked this here. Thanks for your suggestion. I'll post it as a question.

The language doesn't matter at all. There's no such thing as a service that "supports C#".
It's always the other way around. Can you write code that properly consumes the service?
|
|
|
|
|
Do you mean a free service that you can use to get the meaning? In that case it doesn't matter what language it is written in as you can consume it in any client.
As for open source code that provides exactly that - the answer is "probably not". A webservice is quite simple to write, and you are basically asking for a lookup service. Most tutorials will already give you that basics.
Only thing you'd need to acquire is a free dictionary. You could use the wiktionary for that.
You'd be getting defintions of the words by the way; meaning of the word may vary by locale and context and cannot yet be determined by machines.

I have an application that creates an Excel workbook from a template. After the workbook is created I populate each Worksheet. I'm attempting to make the cells that contain headers and other data describing text read only.
Here are my latest two attempts:
Worksheet ws = m_wkbk.Sheets[1];
ws.Activate();
ws.Range["A1", "E1"].Style.Locked = true;
Range range = (Range)ws.get_Range(ws.Cells[1, 1], ws.Cells[1, 5]);
range.Locked = true;
|
|
|
|
|
Excel only locks the locked cells when a password is put on the sheet.
Every cell has the Locked attribute set on new sheets, you unlock cells you want to allow users to change then set a password on the sheet to protect the locked cells.

Correct. 
There are two kinds of people in the world: those who can extrapolate from incomplete data.
There are only 10 types of people in the world, those who understand binary and those who don't.

A sheet can be protected without password.

My apologise, your right, I just never used it that way always had passwords.
|
|
|
|
|
And what is the result of this ?
ws.Range["A1", "E1"].Locked = true;

It runs but has no impact on the launched sheet.
