Hello. I copied "LCD_4bit.c" and "LCD.h" files from Keil examples folder to my project folder and add it to my project. Then I changed Pins definition in "LCD_4bit.c" according to my project board LCD pins(LPC 2378). (I don't think that The problem is here.) Then I could successfully Build it, but when I download it to my project board,there is no signs that LCD works. However when I compile "LCD_4bit.c" in IAR environment ,the produced "hex file" works well on my project board. Thanks for your help.

Yes, of course - for any timing loop you would have to disable interrupts.
That was already covered in the linked thread: www.8052.com/.../149030
