This approach requires you bundle some crypto libraries with your software, and most algorithms use quite long signatures, for security, which will make your serial numbers pretty tedious to type in. It's OK if you expect users to copy-and-paste the numbers.

What I have done in the pasted was create a public key and private key. The public key would be given to the user to validate the product. When they validate the product or login to the system the public key would be checked against the database and the return value would be the private key. During all the interactions with my C# program should the user need to check for updates or pull information from my server the private key would be added to the query to the server to confirm the end user was legit.
Another method I have also used is the above but added additional checking to confirm the user wasn't sharing the key. The C# application would obtain the serial number of the processor in the computer and upon registration of the application it would save it to my database. Then if someone else tried to register the product with the same Public key but different serial number of the processor it would throw an error and they would need to contact support. You can do this to allow 5 different machine ID's or how every many you want.
You could also however create a registration key based on a name or company name that someone provides and add that algorithm to your C# program. The downside to that is C# source code can be decompiled easily the algorithm can be found to create a registration code easily without someone actually paying for the product. By adding in a server that does the authentication it is much more difficult for someone to generate their own serial key.
I would draw the whole thing manually since I would like to populate the whole list of dynamic products as well as attach scripts to allow updating the total column at the bottom.say you have a master table called order and a detail table called order_detail, you want to show all products on a list with a quantity input, then on submit you will loop through the list and determine those that have quantities,let phpmaker add the order record then on row inserted insert appropriately into the detail table of that order.
Assume all your products and thier unit prices are in the product table.
setup the gridAddrowcount of the sale_detail table to draw the exact number of orws equal to number of products.
Go to page load event of the sale_detail list page and paste
function Page_Load()
//set count to number of products
$this->GridAddRowCount = ew_ExecuteScalar("select count(*) from product");
All registered users can get all minor version upgrades free of charge after purchase. A minor version upgrade might add small features, improvements and fix bugs found in the previous versions. The first part of a version number is the major version number, if it is not changed, it is a minor upgrade. For example, if you have version 1.0 of a product, then versions 1.0.0.1, 1.0.1 and 1.1 are all minor version upgrades.
Upgrading to a new major version of a program always requires an upgrade license. The upgrade fee will normally be 50% of the standard product price. A major version upgrade adds lots of new features, and may even be largely rewritten. Major upgrades are released typically once every year, but it may be sooner or later. If the first part of a version number changes, it is a major upgrade. For example, if you have version 1.1, then version 2.0 is a major upgrade and an upgrade license is required.
The "Random" extension provides a new object-oriented API for generating random values in PHP. It includes several classes ("Engine"s) that implement different algorithms for generating random numbers and storing their state within objects. This allows for multiple independent seedable sequences, which can be useful in certain contexts, such as testing or simulation.
I will debug the table again. Notice that i've been using phpmaker for years now, and on every project i was having this issue. It is the first time i see the table list ordered with a lookup field on list page without clicking on column header.
I got package_master table in which I have defined how many products in each package ex: pkg1 as 20 products, pkg2 as 24 etc. I want to achieve this Whenever user selects package while placing order automatically orderdetail field should come for number of product. to explain in term of demo app. When placing order orderdetail comes below and u can add or delete number of line items. I want to restrict this line items to the number of products in my package. If I have 20 products then application should show and accept only 20 or less.. it can accept 19 but should not accept 21 and above. same restriction should be for edit too.
You may need to write your jQuery code to count the number of rows in detail grid table and get the value of products (not sure if this exist in current page, or need to get in other table). Then hide the "Add Blank Row" button if rows exceed limit.
This says nothing about how sites were developed in terms of good coding practices. For example, if you took unskilled (for lack of better terms) programmers in each language, these numbers could be reversed and perl could have the most vulnerabilities, with .Net having the least. It all boils down to what the code itself is supposed to do. Has the code been programmed to perform its sole function with tampering/abuse tested before it was put into development?
In order to migrate their products from custom older versions of ADOdb back to the core product and take advantage of the active development of the product, as well as compatibility with PHP 7 and later, a number of users have submitted their custom functionality to be integrated into core. If you are in the same situation, contact us about having your feature added.
I think you will find PHP Maker a more capable product than Appgini, but it comes with a significantly higher price. Likewise, PHP Maker seems to have a lot more options than Appgini, but you get more complexity with those options, too. Ultimately, it is going to depend on just what you want to get out of the program. If you need a quick, basic database system, either product should do the job. The more control, customization, and additional features you want, the more challenging the choice will become and, I suspect, the more expensive will be the solutions that best fit your needs.

In this example, when you select a product from combobox, the script know the product ID from the option value, so it can use the ID to locate the product from the same lookup table (your product table) and retrieve other field values such as the product unit price and fill the target fields. Allow sort/search Enable sorting and searching of the looked-up values. For use with Select (combobox) or Radio or Text Edit Tag only.

As with most coding software, there is a range of options available to you. Along with free and paid PHP code generators, there are also basic and complex generators. There are a number of very good free code generators that will allow you to do things like create basic PHP code for connecting to and editing MySQL databases. If you need something complex, paid generators are available that allow you to create applications, generate web forms, and produce graphs and charts.
This PHP code generator is both responsive and web-based, so you can generate code from a PC or smartphone browser. If you're new to generators or PHP, this is a good tool to start with, and the site features a number of examples and tutorials on how to use the code generator.
The ability to have multiple people working on projects as well as to use multiple databases makes this PHP code generator a great choice for a business environment. It also allows you to take advantage of a number of features that may be beneficial for websites, such as integration with Google Maps and YouTube, so it is an excellent choice for in-house database management as well as for generating code for a website.
PHPRunner uses wizards for creating a number of database driven applications, including forms, grids, reports and charts. It uses a templating engine and allows more than one person to work on the same project. As with most other generators, it supports a variety of database types, including MySQL, MS SQL Server, MS Access, Oracle, just to name a few.
This tutorial builds a simple and extendable inventory system in less than 50 lines of code. The progressive style of these tutorials also helps the reader to ultimately become more familar and comfortable with phpGrid by introducing a limited number of new phpGrid features in each one.
The last point is particularly important. By logging debug information as your PHP scripts are executed, you can see how your scripts work in production with real user data. Without logging, you are limited to your own tests.
