Hi,
I am currently working on the altera cyclone II development. How can 
make the gpio pin of FPGA high through the VHDL program?

This is the most usual way:
gpio_pin <= '1';

If thats not the answer you expected: maybe your question is missing 
some infomation...

That's correct, but when i assign a gpio pin in the pin planner and 
checking the output voltage of gpio using multimeter, the value is not 
expected one!

Did you connect the right VCCIO to the Bank of the GPIO that you would 
like to use ?
