Hi
If you go to the Learning Centre here:
http://www.matrixmultimedia.com/lc_index.php
You will find all sorts of valuable links that can help.
For instance selecting
'Flowcode Examples'
then clicking on components, will download to your PC a zip file containing loads of examples.

For LCD:

Then you can load each example to teach you how to send numbers, letters etc.
With your 16F877a Configuration settings should automatically be set for you.
If using any other target device, for configuration settings see the link thats a part of my signature.
If configuration setting are not correct, then nothing will work as expected.

As for hardware connections to LCD, take a look at the data sheet for LCD Eblock EB005:

After you have taken a look at the examples, if you're still stuck then we help you further.

Thanks for the help.

Most like to be able to draw on the display, creating different characters.

Or even create drawings using the 16x2 display.

Write characters and numbers I've got.

Thank you.
