Extract icon's from almost any file (exe,lnk,......)

[Spider001]

This is written in c# maybe it can be implemeted in autoit.

Or if some one has time and can transfer this to autoit code?

For now i use it this way and on a later time i try to transfer it to autoit code.

SHGetFileInfo can be found if you search the help file. It's part of the WinAPI UDFs.
