Here, I do this to subscribe tags continuously but CPU is taking more here.
I have couple of other queries also,
1. How do I check server status? whether its running, disconnected and etc? Is there any QuickOPC API for this, as per as I searched I could not find one.
2. My application taking around 50MB of RAM consistently, In that around 17MB is my application(private working set) and 42MB is shared working set. In that case quickOPc assemblies are taking 42MB?
Please clarify.

If their bitness differs, you will need to do some editing of the .REG file, because the 32-bit part of the registry is actually located under a different key on 64-bit systems.

Just to confirm I am putting this question,
I have created .reg file from 32bit registry location since mine is 32bit app. Now, I need to open this registry file in my client machine right? Please correct if my understanding is wrong.

A third option is to store the license into directly into the registry. I will send you a document with instructions to that, to the email address you used to register with these forums.
There is currently no way the license could "go" into/with our or your assemblies.

I do not want to install anything in my client machine on license regard, My binaries should go with QuickOPC license. Is that possible? Please let me know how I can do that?
Thanks

I have another queries,
1. As per the "Application Deployment" section you mentioned, I need to copy LicenseManager.exe utility to client machine and install the license?
2. Or I need to install QuickOPC version 5.40 in client machine and install license using LicenseManager.exe? What if I am not allowed to install anything in client machine?
3. As of now, I have installed license in my development machine. Therefore, I need to copy these binaries to client machine and registered it?
Please let me know whats the proper way to do this and correct me if my understanding is wrong.
Thanks

QuickOPC establishes/closes the connections automatically, and you cannot influence that explicitly (aside from setting some parameters that dictate how long it stays connected when not in use). Also, OPC XML is somewhat special in this respect, as the method calls are HTTP based and thus, per themselves, only represent short-lived connections, which repeat over and over (using a "polled refresh" approach).
