Windows Software Assurance per User is a new way to license Windows, putting users at the center of licensing for their devices. This provides simpler license management because you count only users with primary PCs, instead of counting every single device. Server and Cloud Enrollment. The Server and Cloud Enrollment is an enrollment under the Microsoft Enterprise Agreement that enables you to commit to one or more key server and cloud technologies from Microsoft.

In exchange, you get the best pricing and terms, plus other benefits such as cloud-optimized licensing options and simplified license management. Best pricing and terms for server and cloud products, including discounts on new licenses and Software Assurance. Full Software Assurance benefits for all deployed licenses, including new version rights. Unlimited Problem Resolution Support for qualifying customers.

Move to the cloud as needed and grow organically without losing the value of your existing investments. Easy on-ramp to the cloud because Microsoft Azure is automatically available when you enroll in any of the other components; it can also be licensed standalone.

Application license mobility to the cloud through Software Assurance. New subscription-based licensing gives you more flexibility when you need to retire workloads, consolidate, or migrate to the cloud. Simplified licensing management streamlines overall deployment and management. Standardized terms, conditions, and discounts. To enroll, you must make an installed-base commitment to one or more of the following four Server and Cloud Enrollment components:. Customers with any of these enrollments should work with their Microsoft representative or partner to develop the best transition plan.

It is an example of how you can have different license types that offer various features and parameters for customers.

Mostly, users probably will use the Standard license, but those who need more advanced features and parameters will gladly pay more for the PRO version. If EA does not have it the protection and License Key authorization will work fine, but it is strongly recommended to have the strict property set. You need to copy and paste each of then one at a time to your EA code.

In the next steps, I explain where exactly you need to add each MQL4 code section. Now you can switch to the MetaEditor where you have your EA open and paste the code in the right place.

Do not change its contents and keep it secret. It is the section where you can control how License Key authorization should work for your app. The EAL system will prepare everything for you, but if you have some MQL4 knowledge, you can change some parameters yourself to fit your needs. Otherwise, set it to true.

Uncomment this parameter if you want this EA to use License Key and authentication. Comment this line to disable License Key and all authorization functions on the EA. It means if EA cannot authorize the License Key for minutes 96 hours or 4 days it will shut down.

We set the long period on purpose, which means if your server is down on Friday night and you are away for the weekend you will still have time to fix things when you get back on Monday.

It is the same for all your products. Leave empty to disable all auth functions on this app. The other three sections contain less MQL4 code than the first one, but they are essential for EA functionality, protection, and License Key authorization. Also, make sure that your OnInit is of int type. The older MQL4 code might have some other type, for example, void. Having any other type than int for this function will not compile your EA. If your EA needs code upgrade after you change this from void to int , then you should contact your developer about it.

You need to make sure that your MQL4 code meets the latest standards. Some EAs might not have the OnInit function at all. In such case you have to create it which means simply adding this code:. Also, make sure that your OnTick is of void type, and your OnCalculate is of int type. OnDeinit usually does not exist in Indicators, but I recommend adding it for the best experience. We got 0 errors and 0 warnings. It means the EA was compiled successfully and the EX4 file was created.

Notice this time the MetaEditor compiled two files into one EX4 file. It is because we have instructed to include the EAL library file. There is nothing to do with this folder for you, but still, it is essential to know where the EA store encrypted license keys.

This code is always the same for all your products. If you double-click the EA or drag-drop it on the chart, you will see the EA properties window. Switch to the Inputs tab to find the LicenseKey parameter. It is where users need to put their License Key to start using the EA. Note, that EA needs only one successful authorization with the correct License Key. After that, users might start the EA without the License Key on the same computer.

In such a case, the EA will read the License Key from a computer disk. You will see a small keys icon next to each user. Click the keys icon next to the user for whom you want to create a new License Key. You can change any of these fields later if needed, but be careful and make sure you understand how changes will affect the License Key. You can find User ID on the Users list. The user ID cannot be empty or zero because each License Key must belong to someone. If you come to this page by clicking the keys icons, then the User ID field should be already prefilled with the correct User ID.

To the right of this field, you can see the User ID of a currently logged in user. If you click on it, it will set the User ID to that value. It is useful if you are creating a new License Key for yourself or just testing it. License Key — it is a unique automatically generated License Key for a particular product license for one user. Every time you come to this page, it will create a new unique License Key randomly. You can type any other License Key here if you want.

Expiry date — it is the expiry date of this License Key i. Type for no expiration lifetime access. If this License Key is linked to an active subscription ID e. Purchase date — it is a purchase date for your reference. It cannot be empty. Enabled — it is the status of this License Key.

If Enabled, the user can use this License Key. If Disabled, the user will not be able to use this License Key. Transaction ID — it is a transaction ID or receipt ID for your reference as it appears on your payment processor account e. It can be empty if you create the License Key manually. Although it may be useful in real trading, the main purpose my EA is made, is to provide some backtesting benefits to the user. I have seen that some of the programs on the market here are working in this way, so it is possible and allowed.

I just would like to know if my approach the code above is right, and if not, to receive some advice and direction how to accomplish this functionality. You don't have to take care of that - I guess. That's why Metaquotes offers their system of the Market. Download from the Market a free EA or indicator and try to start it on a different locale terminal, e. My question was how to get an information in runtime if the current instance of a paid EA has been bought, or not.

Do detect in runtime if the current downloaded instance of the EA is already paid by the user, or not, according Mql5 market terms. What's your problem actually? You asked questions, but the code you posted is the answer to these questions. Of course it works to check the licence type.

If you want to test your code, just simulate the licence type to test. My problem was, that when I submitted an EA with a similar code for checking the license type, for moderator's approval, I received as an answer, that the EA stayed in demo mode. I put my question here, enclosing the corresponding part of the code, as I do now, but I didn't receive an answer if the code I posted was working, or not.

So, I didn't know what to do further. I was convinced that my code was working, but the moderators insisted otherwise. I couldn't emulate their testing environment communicating with Mql5 market server, etc. Of course, I could have been wrong in my former code, so now I post this one, in order to have enough confidence, before submitting the EA to the moderators. I saw you were using the right functions but didn't check it in details. So I suggested you to test it. You don't need to emulate their testing environment, you just have to simulate the licence type.

Comment your "licenseType" initialization line. Try each value and check that it's doing what you want. It did not work for scripts and libraries in past, and I don't have an updated information. Your attept to read license from a file in else branch violates the Market rules, not to mention it seems having a flaw a user can craft a file.
