U mean the client machine also have LicenseManager.exe got installed? I have registered only few dll's by
regasm, in that case also I have LicenseManager.exe in client machine?

One more question, How I can ensure connection with XMLDa Server is established/alive? Is there any specific API for this? As per as I searched I could not find one?

Please help.

"Single Developer + Runtime Free" is not a free license.

It is a paid license which allows one person to develop, and in addition to that, subsequently use his results in production ("runtime") without further payments (that is the meaning "runtime free").

There is no free QuickOPC license for production usage.

Okay.

In EULA, Its mentioned as Single Developer + Runtime Free License. I am not exposing Development capabilities to end user, In that case I should get free license right since I am single developer.

Please explain below statement if I understood wrong.


Single Developer + Runtime Free License � you have the rights to install the SOFTWARE PRODUCT for DEVELOPMENT purposes by a SINGLE USER ONLY.� If you will be installing the SOFTWARE PRODUCT for DEVELOPMENT by more than one user, you need to purchase �Additional Developers License� for each user that will be using the SOFTWARE PRODUCT for DEVELOPMENT purposes.� You may distribute applications built using these components along with the runtime portions of these components without payment of additional license fees under the following conditions:

You do not expose the DEVELOPMENT capabilities of these components to your end users.
You are writing a custom application for use in your facility, as an operator interface on machinery that you are building and selling bundled with the software, or you are a system integrator creating custom software applications for your customers and you are NOT providing source code or development capabilities for your applications to your customer.
You are not selling an off-the-shelf packaged software application. ISV/OEM licenses are available for this use case � please see the �ISV/OEM License�.

Yes, for any kind of production usage, whether it's "continuous" or not, you need to purchase the product.

Ad 2. You need to know when you want to stop. We cannot know that. while(1){} is going to consume CPU unnecessarily, plus won't give you any option to exit.

Thankyou.

ad 1 is clear.

ad 2, Suppose given time is continuous, I can introduce while(1){} to process item changed events continuously. Is there any event/trigger to break my loop which is continuous.

on simple words, How I can run item changed events continuously?

Thanks.
