Ismael,

There is no direct equivilent in VFP, however you can create your own method to work out the x and y twips values.

LOCAL lnHWnd, lnHDC	
LOCAL lnPixelsPerInchX	
LOCAL lnPixelsPerInchY	


#define LOG_PIXELS_X     88				
#define LOG_PIXELS_Y     90				
#define TWIPS_PER_INCH	 1440			

declare integer GetActiveWindow	in WIN32API
declare integer GetDC		in WIN32API integer lnHDC
declare integer GetDeviceCaps	in WIN32API integer lnHDC, integer lnCapIndex

lnHWnd = GetActiveWindow()
lnHDC  = GetDC(lnHWnd)

lnPixelsPerInchX = GetDeviceCaps(lnHDC, LOG_PIXELS_X)
lnPixelsPerInchY = GetDeviceCaps(lnHDC, LOG_PIXELS_Y)

with ThisForm
	.nTwipsX = TWIPS_PER_INCH / lnPixelsPerInchX
	.nTwipsY = TWIPS_PER_INCH / lnPixelsPerInchY
endwith

I think I got this code from MSDN but as you can see it updates two form properties with the X and Y twips.
