I have written preview handlers for a couple custom file types. These file types don't have an application by default that can open them. I want to associate an icon with the file types as a signifier that they are custom.
I have tried setting a registry entry for DefaultIcon
in HKCR.<filetype>
, but it doesnt appear to work, even after reboots. I do these registry modifications from C#, and the modifications are successful.
The icon file is simply an ico file residing in %APPDATA%
for the moment. I plan to add a few more icons, and put these in a dll file. I just want to get it to work before I take those next steps.
How can I set this icon?
