I did not send a solution, I asked a question.

So, no, can't do.

You already mentioned that. I did (and will not) post a solution; there's a question that needs to be answered to find out what might be going wrong. If you are having trouble with the language, try and find someone who can help.

Developing a Point of Sale System for Reataurant/Hotel

I started to develop a Point of sale system for Restaurant/Hotel which also include a facility of sms confirmation for customers for home delivery etc.
I think first we need a thermal printer for bills slips etc,
Please give some ideas how to start the project and what types of packages or tools used.

I use .Net C# as a developer.

This forum is supposed to be used to get people help you with with programming issues and not to collect (rip off) ideas/requirements from us.
If you are indeed developing something like that, you should come with these ideas yourself. You might even ask your potential customers for ideas if you can't come with anything by yourself.

Regards,

Well, you START by gathering very detailed requirements from your customer. They're the ones paying you and they're the ones who will dictate what they want, in detail. If they don't get what they want, you don't get paid, so make sure THEY know what they want.

Really, this is a question that you should NEVER have to ask in a forum.

I agree completely with the other responses - you need to gather requirements from your users to know what to build.

A restaurant and a hotel are really completely different businesses. The restaurant may include both what you think of as "point of sale" as well as kitchen systems - printers and screens, mostly - to facilitate the preparation of the food. The hotel presumably needs to be able to deal with reservations, credit card pre-approval, and incidental charges (movies, meals, crap from the little store most hotels have).

There are probably existing hotel systems that include modules for running in-house restaurants, but I would think that the only real integration point would be managing to bill meals back to the guest's room.

The bottom line is that you need to gather detailed requirements for what they want, and you need to understand WHY they're hiring someone to write a system when there are no doubt quite mature systems available for purchase. What do they think is unique about their operation?

If you're a general consultant as opposed to a coder for hire, the right thing for you to do is probably find an existing package that meets their needs, and try to get a fee from them or the vendor for helping the two of them get it going.

If you're going forward with writing something once you have requirements, you should be looking at Microsoft's Point Of Sale for .Net. It's a .Net implementation of the OPOS standard to make dealing with the specialized POS hardware easier.

Point of Sale is its own unique little niche market, and if you're not generally familiar with it (and you're clearly not) you may want to just steer clear.

You really have to learn basics. "thermal printer" is nothing important for the project.
Learn some programming and design, e.g. with the book "Applying UML and Patterns: An Introduction to Object-Oriented Analysis and Design and Iterative Development" by Craig Larman. An example used in that book is a POS, too.

iirc correctly, that means you'd have to get the result from your table as a string - which depends on how the table/schema is defined (you dont show this)

Assuming you can get the value as a string, then

String strbranchExposureFactor = [value from DB]
Double branchExposureFactor = 0.0;
if (Double.TryParse(strbranchExposureFactor, out branchExposureFactor))
// Value is Good 
else
// Value is Bad/?Out Of Range...

Disclaimer : ok, Im not endorsing the 'str' prefix (whats this, Hungarian notation ?) for the String variable, use whatever your conventions dictate/allow

You are really struggling with these basic concepts aren't you. Get a book and work through ALL the examples it will be ultimately quicker that repeatedly asking the same questions in a support forum. As answered the other day.

object oResult = (cmd_BranchExposureFactor.ExecuteScalar();

Now you can look at the content of oResult in your debugger to give you an idea what it contains. As Garth said it is probably a string, empy or null. Now you can deal with it!

Yes. Ultimately it's just a string. The application provides the context.

You can use below code to get both value.

AppSettings["KeyName"].ToString();
ConfigurationManager.ConnectionStrings["connectionName"].ConnectionString;

You need to do it in client side? Use javascript. getElementByTagName(Table) etc. many things are there. You can make variables of table also in javascript. Then you can process what ever need at there. It will be work around only. But you can do.

If you are aiming html of other websites i have very less knowledge only. But i think you can use webbrowser control of visual studio which can(Not sure) inject scripts to a webpage

Thanking you

I would have no idea why you are getting that error. Through some strange circumstance, I cannot see your code, your project or read your mind and you have not provided any relevant information that would allow anyone to know what it is that you are trying to do and what you have done.
