'Unable to load' extension dll if VS.net 2003 not installed

But when I try to use the built dll on another winXP computer (VS.net 2003 is not installed) by directly copying the whole, same directories from my winXP (including apache1331 and php436 & php436src, and php.ini), I got the error message: 'Unable to load dynamic library .php_devarticlesmod.dll'. Then I uncommented 'php_gd.dll and php_ming.dll' in PHP.ini; the system can find them and both can be shown in the page by using 'phpinfo();'. So it's not a problem of PATH since they are all located in the same extension dir. I also tried to copy all dll's in PHP related DIRs to c:\windows or system, or system32 and tried to add PHP related DIRs to system PATH, but still got the same error message. Finally, I get another winXP computer with VS.net 2003 installed and try again (without building the dll again), and it works this time. So I think the extension module I built is somehow dependant on something of VS.net 2003, but I don't know why. Could someone please give me a hint to resolve this? Regards, Paulkk,
