Well NVP stands for Named Value Pair, in which you send "Name=Jim" as a NVP
Credit card processing can be separated into these categories
TIPS or MANUAL CHARGE
So you have to AUTH FIRST, then CAPTURE.GET BALANCE is for gift cards. The rest are back end functions, But remember, you always have to capture at some point, like the end of the day.
1. I don't see the purpose for IPN. If a customer has a dispute, they call you first. Why would I want a IPN to tell me they disputed the charge, it should never go there in the first place.
I can't see how PayPal can accurately calculate shipping, sales tax and discounts.
Shipping is based in dimensional and gravitational weight of about 160 lbs and girth of 165. Girth (2x Width + 2x Height)
Each state is different, in California, services are tax free, the state is about 7.0%, my county is .75% for 7.75%. Shipping is non taxable.
Discounts always come off the subtotal before tax and shipping
Well from looking at your code, you seem to be a confident programmer. But take no offense, with all due respect, you seem to have no clue about running a store or a small business, and do not realize how large the scope of calculating Sales tax, shipping and discounts are. There are basic formulas, but someone has to assign the values for every item in the store first in order to calculate them, unless you only sell 1 product. Now you have 48 states, and Alaska and Hawaii which is minimum 2 day air at about $15 to $23 dollars for about 2 pounds and 25 inches of girth.
PayPal is a terrible service to use, and very expensive. If I as a store owner was told I have to use PayPal for my online store, because the programmer told me so, I would laugh. I'm not paying $25 a month plus $3.25 for a AVS lookup, and I think plus 3.7% total for each transaction, plus .25 each per batch capture. If its American Express, Add $5 per month more for $30 a month, plus 3 more points minimum.
Consider having the customer qualify for a merchant processor account first, and that the website you made meets the minimum requirement for approval first. Then select a payment gateway from the available choices.
I wrote this article years ago on payment gateways and merchants processors. I may port it over to a code project tutorial in the future if they let me.
Thank you for taking the time and effort to write a considerable amount of detailed information, its greatly appreciated.
I was devloping the project for myself, and chose paypal because it states that there are no charges for website payments standard except the transactional charges which as you rightly stated are approximately 3 to 4 percent of the total value of the transactionand the most expensive product is under £25 (GBP).
Still, you've given me lots to think about and possibly even seek a readymade cart to implement, although I was really looking to cut costs and hence thats why I opted to have a go at developing a solution to my problem myself.
The issue to do with shipping is definately a major one (for me) as shipping costs vary for shipping to different countries as you so rightly stated.
The reason I opted for paypal was because so many people already have a paypal account (which they use with ebay).
Thank you very much for your input and its made me go back to the drawing board to re-asses everything.
PayPal was the 2nd Payment Gateway I wrote in 2003, first was Verisign, both were CIM. Then I wrote my first real AIM Module for Authorize.net, and wrote AIM ever since. I have potential customers that want CIM, so they don't have to get a SSL certificate.
As far as the EBay factor goes, Magneto seems to be doing a good job at taking the EBay customers. EBay pumped money into them 5 years ago, and then bought the company with their Skype Money. Magneto was smart and charges about $2500 US a year to use the program, they have a lite version that's free to use, but very limited.
Calculating shipping was the hardest program I have ever written. It took me 3 years to figure out how to add up all the mass, and divide it into package units, or pallet units, and then submit each package in a loop for a single quote. I've been running the shipping module for 3 years now, and have got the accuracy up to 99%, always a bit over the actual cost.
So I have this eCommerce program, been working on it for 5 years now, and it's almost ready for mass marketing. I want to change the name of it first and trademark it. I have a few more things to fix like the multi-threaded email delivery system.
I was going to port my program over for European Use, but I don't live in Europe, and I have no clue about shipping companies, payment processors and what languages I need to support.
Let me know what you decide to do. I'm curious to see where the path of least resistance takes you.
I can appreciate that shipping calculation is complex, yet I was under the understanding that the best option to calculate shipping was to take the most common shipping companies ie UPS and DHL (to name two) located within the geographical areas of the sellers and then possibly to register with them for updates on price changes or to write a script that would crawl their website pages (the pages contaning the fee's) and them to save those details in an sql table or xmlrepository and use those figures based uponthe buyers selction of preferred couriers/shipping agents.
Having said that, I must admit I'm not that up on IT and developing having never gone to college or university for formal training. Whatever limited knowledge i have i have gained from hme study after work hours (when employed) or during freetime, from books purchased in the highstreet stores. I must admit I like the mental stimulation of having a problem and trying to resolve it by coming up with your own solution.
I must also admit my solutions arnt always the best hahaha, though I do try. Generally as can be expected I feel the best route is usually the tried and tested text book method, though sometimes its mind-bending to say the least, and now i'm getting older (47) the old brain isnt what it used to be!
As you so rightly stated in your last post, ultimately someone somewhere has to enter the data into the SQL repository (usually the seller i would assume). Alternatively the seller could choose from a predetermined list of shipping charges based uponthe couriers (DHL UPS etc).
As for languages, I'm not very sure but assume that the no one language is universally spoken in all of europe, your bound to find a largeamount of people who dont speak a given language and that the MOST common ones (to my knowledge) are English, German, French and Spanish. I would think if you cover those four then you have close to 70%-90% of the bases covered.
From the way you talk I have no doubt your knowledge of prgramming/devloping is far superior to mine and no offence was taken in your last post where you stated the obvious (that i have no idea of the complexities of shipping etc).
As for letting you knwo which option I choose, I'm still undecided, and unsure what to do next. This is mainly factored to funding being unemployed and (hopefully) between jobs though I dont want to get my hopes high hahaha.
My initial thoughts were that the seller would enter the shipping rates for shipping his/her/their goods to the buyer in a similar fashion to ebay and therfore releasing me from the tedious issue.
I chose website payments standard because its free to begin with apart from the transactional fee's which in all honesty is more or less an everyday thing, what with the way Pay as Go for everything is available now including cable tv and mobile phone coverage and even car insurance can be bought on a daily only basis (though i would imagine its quiet expensive)
I'm still chewing over what route to take, the easiest way out is to obviously purchase a third party product and implement that but its not something i can afford i should imagine.
I guess in the meantime i will keep trawling the net to find a sample that even idiots can implement hahaha
In totl i got total price but i am not able to display it... Loop is not go in Else Loop.............

Thanks for giving time to read my problem and also for your valuable suggestions.
Given that you know already the NAME and VALUE of the data to be written to the cookie,
Its not so difficult to check the length of the data (to be written) including the name and then subtract that from the maximum size allowable for the cookie and then you will know EXACTLY how space you have remaining (in the cookie) to work with.
I have this CheckBoxList control and to each ListItem of it, have set the Text property to the img HTML tag so it displays an image.
I am trying to remove the tick/check box from the checkboxes of a ASP.NET CheckBoxList control when i click on each item.
My code does this. Every time i click on some check box, the **SelectedIndexChanged** event fires up and it does some saving of some data in my database. And when the saving is done and the page is refreshed i want to check/tick box of the checkbox item that was clicked not to be there anymore and the checkbox to be disabled cause i don't want the user to able able to click it again. I have tried to tried to set the Enable and Selected properties to False, and also add an attribute to the CheckboxList control, but without success. Here is my code.
We are in the process of developing an inventory tracking system and one part of this system is the automation of the Change of Location (COL) form. We have the database developed; we have the electronic form developed; we are now at a halt because we need this web service inorderto move forward.
1We are in need of a web service to transmit information between Sharepoint and an Infopath form.
2.We will set up your web service as a data connection and work with the form through this connection
