You mean to say for programming hex file into microcontroller and reading back the hex file, correct ?

Do you have any programmer for this, otherwise you can use ISP programmer through serial, JTAG or parallel port.

yes sir

Explain bit more about your project, what hardware & software you have got for it.

sir actually In my PCB board the usb port which is connected to atmel atmega 644P microcontroller and the FTDID2xx driver which is connected between USB and Atmega 644P microcontroller  and my project is to load the hex file to the atmega 644P microcontroller  through the USB port in which FTDI D2xx driver which is connected between the usb and microcontroller. and i need the GUI screen to load the hex file to the microcontroller.

Thanks and Regards,

sir i want to load the hex file through the USB port only we can't use JTAG or SPI

You can use ISP Programmer Pony Programmer ( http://www.lancos.com/ppwin95.html) and try to call it from LabVIEW.

ok sir i will try that one.

sir In pony programmer we can't read it from the USB port we can read it from SPI itself but i need the GUI to read it from USB port.

It means your USB port dont have connection with Atmega SPI programming ports (MOSI,MISO,SCK,RST,GND). You need to make an ISP programmer cable for it, which is shown in link http://www.circuitstoday.com/isp-programmer.
