Can Develop OPC XML DA C++ client in Visual Studio 2015?

Hi,

In .net based demo application its not reproduced since the below exception is handled, and its showing exception "The Operation has timed out"
, please refer .net based demo app threads and callstack.

In case of C++ application no exception is handled, after entering into ReadMultipleItems(&pArgumentsArray) function I am disconnecting internet and it keep hangs there only. refer attached image.
And I also created threads n callstacks for my c++ application, I feel this one is having manged threads.

Please check it and let me know if you need any other info.

Thanks

It can easily reproducible by disconnecting server (Internet connection) even i am trying the same only.
About, thread list and call stacks are not coming for managed code. I tried multiple ways.

Hi,

Any help on blocking calls of this below line,

ResultArray.Attach(ClientPtr->ReadMultipleItems(&pArgumentsArray));

Its keep blocking if server is not stable, instead of waiting infinitely can we make non-blocking (timeout after some time) ?

This issue becomes critical for us, Could you please support, We do not have any control once its blocked on above line.

Thanks.

Okay, Let me try. And you also can reproduce the issue by disconnecting internet while running sample ReadMultipleItems. I am trying the same with sample, since I don't have that luxury to disconnect actual Xml server in production.
