Hi everybody

http://forums.ni.com/attachments/ni/170/281385/1/CAN_AVI.llb has the CAN_AVI.llb

The "webcam_can2.vi" is included in the library.After opening it the error about the  "wecanusb.dll" appears.

How can I use this VI.How to fix this error?How can I find wecanusb.dll or should I write it by myself?Could you help me please?

OR can I find any VI to analyse the video and get the acceleration information?

I am looking forward to hearing from u.

Thank you

Hi Jeronimo,

Again, please provide a link to the thread you're getting this attachment from, not a link directly to the attachment. The error means you are missing a DLL.

Hi jeronimo,

Ok, after doing a search for the actual thread you're referring to, I found this one: http://forums.ni.com/ni/board/message?board.id=170&message.id=281385&requireLogin=False

Assuming this is what you're talking about, it seems that the DLL is the other guy's custom DLL so you probably won't be able to get ahold of it. It is not a NI thing and I don't see anything come up after a quick Google search. Sorry.

Thank you very much . I see ...

Can you help me about writing the missing dll?

I am not very well  in programming.I have looked to the examples about how to write the dlls and downladed LabWindows CVI .

Is it enough to know the input and the output that the dll C program will do and the data type?

Could you help me please? 

Can I find any VI to analyse the video and get the acceleration information?

I am looking forward to hearing from u.

Hi

For the VI in the attachment (from the CAN_AVI.llb) the problematic part is the  " call library function node" which is defined as the wecanusb.dll.

What should be done ? How the input parameters should be processed to be outputted by the " call library function node"  block  ?

thank you..

Hi HIDIR,

I would love to help, but it is impossible to do without knowing what it would be doing under the hood. I'm sorry but I think this is likely a dead end.

You probably can retrieve the expected inputs and outputs by reviewing the Call Library Node properties, but that's it. Sorry.
