With this code, you can incorporate self-extract functions to your VB program. You can actually add a compressed file, with you own custom compression algorithm to a EXE, so you can extract it just by running your program (just like WinZip's SFX modules), you can save your application's setting in it's executable(so you don't use the registry, or INI files), you can even put the registration information inside the exe(for safety), so you don't use external text files, or just put a DOC file inside an exe so a user can see it's contens even if it doesn't have Microsoft Word. This are only examples, but the posibilities are UNLIMITED. You can implement this to your program just by adding 2 functions, and calling them. By the way, it should work with almost any VB version. Included is a sample app, that shows a sample Self-Extract maker (which can include any file in the Self-Extract module, which is a VB app), and a Self-Extracting module, and of course, source code.
Enjoy!
P.S. If you include a zip into the Self-Extract module, some uncompressing programs will think it's a SFX, and you can decompress the files with them! (tested with WinRAR -- will say that the zip has a bad header, but will decompress the files!)
