Using common programs in different versions of VFP

[Demetrios Panayotakopoulos]

Hi,

Is possible to include in some programs commands that would be ignored
or taken into account based on vfp vesrion during compilation?

For example
MessageBox in VFP takes 3 parameterers and in VFP 9 takes 4 parameters.
If I try to use a common program that calls MessageBox with 4 parameters
and try to compile it with VFP 6 reports an error.

Is it possible to bypass this problem without using different versions
of the program based on VFP version.

Hi Demetrios.

Yes, but you have to use conditional compilation using #IF. For example:

#define clVFP9 version(5) = 900

#if clVFP9
messagebox(parm1, parm2, parm3, parm4)
#else
messagebox(parm1, parm2, parm3)
#endif

Hi Demetrios.
#define clVFP9 version(5) = 900
#if clVFP9
