Do you have the devices datasheet?

If so, upload it as an attachment or post a link to a download site.

Thanks for fast replay
Here i attached the datasheet of it

According to the datasheet of your GLCD, the device utilizes an ST7920 controller chipset instead of the KS108 compatible chipset as required by the MikroC GLCD library.

Therefore you'll need to either utilize another GLCD library which supports the ST7920 controller chipset or write your own routines specifically for your device.

The following MikroE forum posts seem to indicate the ST7920 is not compatible with the MikroC GLCD library:

I am currently developing an extended text and graphics library for ST7920 based LCDs. The writing is already finished, but I still need some optimization and tests to do. For more information, please check: https://www.mikroe.com/forum/viewtopic.php?f=88&t=51820
