Dropbox-like file status effect

[produktdotestow]

Hi. Is there anybody here who has used Dropbox.com tool for Windows? I'm talking about 'My Dropbox' folder, which is created after Dropbox installation. For example - file pasted to this folder at the beginning has on its icon something, which i can call "updating mark". In background file is uploading to Dropbox server, and after that - file has on its icon "ok mark".

Here You can see how it looks like:


Any ideas how to get this dropbox-like file status effect in my application? What about this functionality, but working with the folders too?

Thanks for Your help,
Mateusz

I found something about 'Windows Explorer Third-Party Shell Extensions'. I think it's it. Have You got some good tutorial how to create own extension?
Thanks.

You are exactly right. This is done by implementing shell extensions.

Firstly, you'll want to understand COM (Component Object Model) and how it works. Then you need to understand shell extensions, and then, finally, icon overlay handlers.

A good introduction is on code project: http://www.codeproject.com/KB/shell/shellextguide1.aspx

How to implement shell overlay icons is described here: http://msdn.microsoft.com/en-us/libr...8VS.85%29.aspx

Note: The number of different icon overlay handlers that the system can support is limited by the amount of space available for icon overlays in the system image list. There are currently fifteen slots allotted for icon overlays, some of which are reserved by the system. For this reason, icon overlay handlers should be implemented only if there are no satisfactory alternatives. [Taken from MSDN. Copyright Microsoft]
