I changed the code line it also didn't work !!
What error do you get?
Can you see COM25 in the device manager?
Well Yes I Can Find it in the Device manager ! 
MikMo:
This look to me like you are sendeing something to GoBetwino AND something that is not meant to go to GoBetwino. That will not work. When you use GoBetwino you can ONLY send well formed GoBetwino commands, otherwise GoBewtino will try to interpret it a commands and fail miserably.I bet you get all kinds of errormessage in he GoBetwino window - right ?

I can't understand how to display the results on Gobetwino. Your Arduino should be connected to the USB port and running your sketch before you launch Gobetwino. You must not have any other applications running which use the Arduino's serial port, such as the Arduino IDE.
well Thanks a looooooot guys !! cause when I removed the code lines
//Serial.print("Inch value="); //print inch text
//Serial.println(inchvalue);
and when I closed the Arduino IDE It Worked perfectly !!!!!!
thanks a looot and all my respect !
you helped a lot !
