I was unable to access the CCS website for the last 4 hours, at least.
But now it's up again.

I wasn't able to access it either.

Your program is way too complicated for checking a button. T ...

I de-soldered the three buttons and connected them to pins B0, B1, and B2 (That way I can connect them to +5v without resistors) however they always read 1 in the program, which is a test one:

#i ...

You need to move on from this, and do the rest of your project.
I finished the rest, all the code is done also, but the only last problem is the push buttons, none of them do anything except button C ...

Yes, that will work.

I used different resistor values for each button (as I cannot find equal values), this is how my buttons are wired:

+5v

You can use 10K or any reasonable value.

Yes, when the button is pressed it will be read as a Logic 0 by the PIC.
Can I use 1k ohm resistors?

Ok I'm going to try and tell you my results.

That switch circuit can't supply two logic states. With that circuit, the PIC
pin is either a floating input or it's a logic "1". You need to fix that.
Change them all to the schem ...

do you have an idea why the following code doesn't function properly?

I need to know how your switches are wired - negative or positive logic.

This is how my switches are wired

Post a link to a schematic for your PIC circuit, including all connections
to the PIC and to the LCD (Power, ground, signals, external components,
values of components, etc).

Use a free image h ...

Maybe some of the i/o pins are not working on that PIC. Try using
pins on a different i/o port.

I bought two new PICs and everything works except for the display...

I don't think you can fix that problem. You have to get a new PIC.
How about the one that for some reason doesn't power the display?

How do you know it's the PIC ?
I know it's the PIC because I mistakenly connected the 12v power to the 5v power lines and the PIC became very hot. So I'm 100% sure it's the PIC.
Edit: My programmer ...

DAMN! I somehow managed to burn the other PIC that worked. Is there a way to fix a burnt PIC? I program it using MicroPro and I get an error:

ROM programming error at address 0x0001

YAY, I got it to work by trying out a different PIC16F877a I had lying around and it worked! Thanks for all of your help.
