Customize Windows Explorer Tooltips

[Little John]

Hi all,

I want to do some customization of Windows Explorer tooltips. I already found some information about this topic.
However, I'd like tooltips of plain text files to show the first say 3 lines of the respective file. Is that possible?

Regards, Little John

I would say it's very possible.

There could be a slight delay if you want to read the text file before displaying the tooltip, or could you create the possible tooltips in an array before use?

cheers

He's talking about making the OS doing that through some possible customization of the registry.

Doing so programmatically in your software is obviously trivial

Yep.
