This is basic question about IDA Pro which I am trying to learn.

Is it possible to make changes (do a patch) and compile the file with IDA pro?
If yes, please could someone tell me how.

Thanks

...and what have YOU done in an attempt to find the answer to YOUR question?

You need to RTFM for IDA, as you seem to be completely unaware of its function.

There are no dumb questions only dumb answers.

RTFM 2 u 2

Actually there are "dumb" posters, and this one has just joined the Goners.

Regards,

Yeah, but it's not just because of this post but a previously deleted one that exemplifies what not to ask here. Tsk, tsk you naughty boy..you really didn't read the FAQ at all did you?
