Finding avaiable scanner properties

I'm trying to set a scanner up to use auto document feeder if it's available. It was working fine previously but I have changed my printer.

I'm sure I had some code somewhere that listed the available printer/scanner options. Something like:


This however doesn't bring up a list of proerties.

Previously wiaScanner.Properties.item("3087").Value gave the current state of the ADF, but it seems with the new printer this just stays fixed at 7.

Can anyone help with code to list all available properties?

Not anything I am familiar with myself, however I did a quick Google and discovered this link:- https://docs.microsoft.com/en-us/pr...wiaaut/-wiaaut-icommondialog-showselectdevice

But it's it's like the old Microsoft help, its barely useful!

This link looks useful!

Thanks. The second like looks useful. I think I'm querying the correct property, as I think 3087 is fixed as ADF status. I'm worried it's something that's not being reported by the printer anymore. When I load a document into ADF it still scans from the flatbed whereas the previous printer would then use the adf.

It seems I can force it to use the adf but I would have to do so manually rather than querying whether it was available first.

EDIT:

I have found a few of my old posts from when I first wrote the code. The properties are all listed here:

so it appears I'm querying the correct one.
