Hi Peter,

You are definitely on the right track. Although the document mostly discusses changes that were made when the IMAQdx drivers were introduced, you may want to check out this document on programmatically setting camera attributes. The main thing you may need to change in your code is to make sure that you are writing rather than reading these properties. To do this simply right-click and select Change to Write.

What you will need to input for 'Active Attribute' and what can and cannot be adjusted will vary from camera to camera, but the basic idea is certainly correct.

Hi Peter,

I see that you have created a number of threads on this topic in the last few days. I am going to link those threads to this one so other discussion forum users who encounter similar issues will have a complete discussion in one place.

Are you still having trouble altering the attributes of your image acquisition? Are you seeing any error messages or are you simply seeing no changes in the acquired images after changing settings. When you reference these attributes in LabVIEW you will have to got through the same 'attribute tree' that you would see in Measurement and Automation Explorer (MAX). If you are not able to alter the attributes in LabVIEW, confirm that you are able to alter them in MAX. To do this select the camera under My System»Devices and Interfaces»NI-IMAQdx Devices, then select the 'Camera Attributes' tab. Make sure that you have selected All Attributes under the View Options button. Snap a few pictures in MAX to confirm that changing the attributes is in fact changing your acquired images.

Thanks,

Hi,

Thanks and sorry for the mess on the forum.

I have already solved the problem, for some reason, the IMAQdx property nodes didnt work for me even though everything was as it should. Instead, I used IMAQdx Enumerate Attribute.vi s and that worked fine.

Thanks again.

It's no problem, Peter. I'm glad to hear you were able to get things working! Good luck moving forward with your application.

Thanks,
