EntryPointNotFoundException calling SiOpenWinInitEx

Post by harem » Sat Apr 18, 2020 5:15 pm

One user is getting EntryPointNotFoundException when my .Net application calls SiOpenWinInitEx. It works OK with other users who both do and don't have 3Dconnexion SpaceMice.

Could this be caused by him having an old driver that lacks that function? Should I make it fall back to not using hints or SiOpenEx if that happens?

Turns out this is because of an older driver and the problem is solved by falling back to the non-Ex functions if that exception is raised. Although that also means buttons don't work using the new way of doing buttons.
