Need ZIP source code or freeware ZIP DLL
I need to ZIP a file synchronously from within VB. I cannot shell to DOS pkzip
because I have no way to halt program execution while pkzip is running
(GetModuleUsage() doesn't work, probably because I am running WIN-OS/2 & OS/2
spawns the DOS box, not WIN-OS/2 so I always get 0 return code on
GetModuleUsage() for DOS programs). GetModuleUsage() works fine on windows
programs, so I need a windows ZIP program that accepts command-line parameters
or a DLL that can do the zipping. Every program/DLL I've found up to this
point is crippleware, so I'm ready to do the zipping myself in VB code if
someone knows where I can get the source. Either that or a simple DLL to zip
just one file. That can't be so difficult as to demand $$$ for.
