    Well considering this is not a Delphi board....

    ill try to answer best i can

    probably becuase VB uses runtimes and stores alot of what it uses in its runtimes while Delphi packs it all into its EXE.

    There are exe compressors out there...for the life of me I cant think of the name of one..I think one of the popular ones starts with a U..

    Is the VB exe compiled as packed code (aka P-Code)?

    This is a M$ exe format that is much more compact than straight x86 assembler...but a bit slower as it has to be converted to assembler at run time...

    P-Code is pseudo-code, and its a cross between a proper natively compiled executable, and the HLL instructions you type into the IDE

    Here's one to try....it works well.

    "the Ultimate Packer for eXecutables"
    http://upx.sourceforge.net/

    From the Web-page:
    "UPX is a free, portable, extendable, high-performance executable packer for several different executable formats. It achieves an excellent compression ratio and offers very fast decompression. Your executables suffer no memory overhead or other drawbacks"

    yeah upx works good, if you want to pay for a brand name product use bit-arts crunch but it works just as well as upx, sometimes i like upx better cuz it's smaller and easier.

    Well as a matter of fact I've managed to shrink the executable of the main application I work on from 820k to 464k by code alone
