dsc 8.20 bug

[cosmin]

HI,
there is an issue with DSC 8.20 and opc client (updated or not) that is bugging me.
Make a new library with an opc client inside and deploying works. Change the name of the computer (restart the computer) and  when  I try  to deploy  a library  with opc client inside it , I get "Visual C++ runtime error, Labview needs to close in an unusual way.....".
Verified with win2000 and winXP with DSC 8.20.

Another issue is that from a computer with winXP the opc client does not connect to a any opc server from a win2000 computer besides OPCLabview ver.6.
I followed every configurations (DCOM and else) specified by NI. From win2000 to win2000 works ok.

I apologize for the lateness of this post. Have you been able to reproduce this error again or was it a one-time occurence? Please let me know what you find.

Hi,

I reproduced this error every time on 2 different machine, win2000 and winXP.

Also, I could not install lv 820 on win2000 with sp2, this i do not see in operating system requirements.

Cosmin:

Thank you very much for your response, here are some suggestions/answers for your questions:

1. I created a library with an OPC server using LabVIEW DSC 8.2 and I then deployed it. After renaming and restarting my computer, I re-deployed my library and everything still worked fine. I am curious as to what you did differently to obtain that error.

2. I would suggest you to see if you can use "Server Explorer" to communicate with your OPC server on the client pc that is running Windows XP and let me know what you find.

3. Regarding not being able to install LabVIEW on a computer with Win 2000 and sp2, Page 3 of the LabVIEW Release Notes mentions that to use LabVIEW with Windows 2000, you must have service pack 3 or later installed.

I hope this helps and please let me know what I need to do to reproduce your issue.

Best Regards,

Rudi N.

Hi,

This is a bit old, since we converted on win2000sp4 for all computers, but I could not connect from 2000 to xp even with server explorer.

You did exactly the same things as me regarding the library and opc client, but i reproduced that error every time, on 2 computers, one with win2000sp4 and the other with winXP.

This is very strange as I tried to follow those steps and could not reproduce the error on two different computers. I will try again on a different machine and let you know what I find.

I hope all is well. I would suggest that you download and install the DSC patch that is posted on our website. I have not been able to reproduce this issue and it may be because I have already installed the DSC patch on my computer. Regarding client-server communication from Windows XP-2000, take a look at this KB that discusses how you can set proper permissions for your client PCs.

I hope this helps,
