If you can run the Release configuration from inside the Visual Studio, but get this problem when running from a different location, then you are most likely not running the same thing. You must be using the very same assemblies (files) that Visual Studio has put into the build output. 
 

Hi

It happens when running it outside Visual Studio. 

Thank you.

Michael

Please clarify whether the problem "running the Release versions" comes

a) from running it from the Visual Studio itself or by running the executable from the folder where the Visual Studio has just built it, or
b) running it from the some derived location, such as when you have built your product installer and then run the installed product.

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.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging

For example:

When JIT debugging is enabled, any unhandled exception

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?

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
