Hi,

When I run the project in DEBUG mode, I can browse OPC DA (or UA) items, but when I run the Release version, I get an exception. See below.

Thank you.

Michael

To enable just-in-time (JIT) debugging, the .config file for this

Hi,

Thank you. This sis now resolved.

Can you please send me the license for this version?

Thank you.

Hello,

parameters have been added to the UIAdministerApplication method since the version you used before. There are are now two Boolean parameters at the end:

opclabs.doc-that.com/files/onlinedocs/OPCLabs-OpcStudio/Late...2~UIAdministerApplication.html

The suggestion is to use True for both of them.

Best regards

Hi,

After installing the new Nuget version and compiling the project, I get the following error:

Error    BC30455    Argument not specified for parameter 'allowChangePrivateKeyPassword' of 'Public Shared Overloads Sub UIAdministerApplication(application As IEasyUAClientServerApplication, owner As IWin32Window, clientSelector As EasyUAClientSelector, allowPullCertificateManagement As Boolean, allowChangePrivateKeyPassword As Boolean)'.    UCMECFG    \MyBin\Proj-VS2017\UCME-OPC\Version 2025.0\UCME_CFG_NET(2,54)\UCMECFG\UCMECFG\Settings1.vb    1    Build    Active

Any idea why?

Thank you.

Michael

Hi,

We shall try this new Nuget version.

Our current version is using Nuget Package 5.80.192. The customer has removed this version and installed an older version that was built with Quick OPC version 2022.1.
Using this older version he could browse DeltaV items with no problems.

Thank you.

Michael

 

Hello,

can you please rebuild your product with updated QuickOPC (5.82.395, now on nuget.org and our Downloads page), and ask the customer to repeat the test and send over the full error message as before? 

The update is not meant to fix the problem, but it adds diagnostic information into the error message.

Regards
 

Hello.

Not a specific idea at the moment. But what we can do is that we can improve the error diagnostics in this particular case, as it is sub-optimal at the moment, and it does not expose some important information about where precisely the error happened. 

I need to assign this to the developer. When it is finished, we will have a new build and I will ask you to re-build your software with it and reinstall on the customer site. I suppose you are on the latest QuickOPC version (2025.1), because that's what we will be updating. Please allow some time for this.

Regards

Hi,

The customer installed the 64 bit version of the OPC Core components, but the problem persists. Any other idea?

Thank you.

Michael

You should be using the 64-bit one. Always (in my experience, it also works on 32-bit systems, which are rare today anyway).

I suggest to change it in your Installshield (there is a 64-bit merge module in the same ZIP as well).

On the particular customer's computer, it is fine to just uninstall the 32-bit components (if they appear in Add/Remove programs), and install the 64-bit components form .MSI again.

I cannot be sure whether it fixes the problem, bit there is a strong relation (it appears as missing OPC proxy for 64-bits).

Best regards

Hi,

Thank you for your answer.
We are using the following merge module in InstallShield:

OPC COM ProxyStub Merge Module (x86) - OPC COM ProxyStub MergeModule (x86).msm  

Version 3.00.108.

This is the 32bit version of the OPC Core components, not the 64 bits.

Please advise how to proceed.

Thank you.

Michael
