Classes and Objects
This code will subclass all the classes locate in a given directory, for example
Home()+"wizards" )

Home()+"wizards" )
Code:
LOCAL lcSourcePath AS STRING , lcTargetPath AS STRING,lnVCXCount AS INTEGER
LOCAL ARRAY laVCX(1)
lcSourcePath = "C:\Program Files\Microsoft Visual FoxPro 7\WIZARDS"
lcTargetPath = "E:\VFP-Projects\A1-FD-Library\WIZARDS"
lcSourcePath = GETDIR(lcSourcePath, "", "Select the Class Librairies Input Directory")
lcTargetPath = GETDIR(lcTargetPath, "", "Select the Class Librairies Output Directory")
lnVCXCount = ADIR(laVCX, ADDBS(lcSourcePath) + "*.VCX")
FOR lnVCXNo = 1 TO lnVCXCount
ERASE (ADDBS(lcTargetPath) + JUSTSTEM(laVCX(lnVCXNo,1))+".vcx")
ERASE (ADDBS(lcTargetPath) + JUSTSTEM(laVCX(lnVCXNo,1))+".vct)
USE (ADDBS(lcSourcePath) + JUSTSTEM(laVCX(lnVCXNo,1))+".vcx") ALIAS VCX SHARED
&& Shared required on USE to avoid a "file in use" error.
SELECT * FROM VCX ;
