Here's a thought: I just opened 3 VFP applications in Notepad, and after the usual gibberish, there seems to contain readable strings, most likely function declaration or something. Within those, the string "VisualFoxProRuntime.6" can be found.

So you could open the file using FOPEN(), then look for the "VisualFoxProRuntime.6" string.

Here's a little code that I just made up and that seems to work:

#DEFINE	C_STRING	"VisualFoxProRuntime.6"

LOCAL x, y

x = FOPEN(GETFILE("EXE"))
FSEEK(x, 5144)  && The "signature" seems to be at position 5144
y = FREAD(x, LEN(C_STRING))

IF y == C_STRING
	MESSAGEBOX("VFP signature found!")
ELSE
	MESSAGEBOX("Sorry, this is not a VFP executable!")
ENDIF

FCLOSE(x)

Note that while it appears to work on VFP6 executable, there is no guaranties (sp?) that it will work on another version of VFP.

HTH!
