Can't load .net assembly (dll) using View\Class Browser

test_man — Fri, 01 Apr 2011 18:31:16 GMT

I am using LabVIEW 2010 SP1.

I have written sample .net class assembly which I am trying to load using View\Class Browser\.Net Assembly\Select Assembly and then I browse attached DLL but DLL doesn't show up in the list.

However I can invoke method manually. i.e. using constructor node and invoke method.

I have attached VI and dll which contains class/methods.

Why can't I browse it using Class Browser?

Hi,

I have been able to reproduce your issue and am currently working on a solution or work around.

Hi test_man,

I am still looking into this issue. It seems that the browse option is not working and I am currently escalating this issue. Just wanted to let you know that I am still working on it.

Hi test_man

I have an answer for you. It seems that the method of Browsing still works but not at the location you were using. The method that works is sidplayed on this vedio:

The method that you were following is not working or at least its functionality is not apparent. I will be filing a corrective action request to see that it si fixed. I hope that this helps.

I just tried LabVIEW 2011 SP1 and it looks like I could still duplicate the originally reported issue.

Hi test_man,

Thank you for bringing this bug to our attention. As Perry mentioned, he has filed a CAR and the issue has been brought to the attention of R&B so it can be fixed in later versions of the software. Does the workaround that Perry posted still work for you?

Regards,

I just tried LabVIEW 2013 SP1 and it looks like I could still duplicate the originally reported issue.

Hi Test_Man,

I followed the steps to try to reproduce the issue but don’t see the error you mention. Attached is a picture of the DLL Properties and Methods from the Class Browser. I am using LabVIEW 2013 SP1. I did the following:

View >> Class Browser >> From the Object Library dropdown menu select >NET >> Browse Assembly >> Browse and select your DLL.

Please let me know if this helps you solve the issue.
