Always use Axicon Workshop to handle icons, but Axicon Workshop is a bit problematic. It does not support duplicate icons filtering, and it is easy to respond when processing a large amount of icon! ()
To this end, I wrote an icon processing tool that automatically extracts icons in files such as DLL / EXE / ICL, and performs automatic icon automatic filtering, icon scans, etc., which is more difficult to process the ICL file, ICL The file is essentially a 16-bit DLL resource file, but in Windows 2000, it seems that there is no function to do it directly. At least I don't know, I have checked Google, I didn't find relevant information, there is no way, only hills, Checked 16 BIT's exe file structure, combined with some read and write code snippets that can be found on the Internet, and then explore and explore, and finally successfully separate ICON from ICL. The key code is as follows: I hope to help you.
