Is there anyone who knows how I can record my waveform chart as an avi file without using any other software other than Labview and its components?
Thankss

Hi there
NI-IMAQ will do the job. If you don't have that, you could search for a solution using DLLs, .NET or ActiveX (maybe DirectX can write .avi, but i don't know)

Thanks for the answer, I have installed IMAQ but nothing has changed in functions palette? What could be the problem?
Also how should I search a dll file for that, I am not that experienced with Labview.
thanks

Take a look at the shot attached to check your function palettes.
I'm not sure if the IMAQ hardware driver brings the mentioned .avi VIs. Maybe you need IMAQ Vision.

Hello dimmib,
there is a example shipped with the VISION Aquisition Software in the example finder. It`s called: "AVI Read Write With Data Example.vi" that is what you want but I think you did not have this additional Software package. Sorry, but there is no workaround for this issue.

Hello Jan,
Thanks for your answer..
However, this is not exactly what I want. I just want to capture what I see on waveform chart and record it continuosly as an avi file?
Is t his possible without vision package?
Thanks...

Hello dimmib,
I think the best way to do this is to make a "screenvideo". In that case you can use any software you want from the web. There are a lot of free tools to capture a screenvideo and save to disk as avi. Without additional toolkits or VISION components I can`t see any chances to get the results you want.
