Pretty non-specific don't you think? Your answer is, it depends. The other program has to be able to be communcated with to begin with. Each program could be different. Google "office automation" and you should get mountains of results on how to deal with Office.

You start by doing some research. Like reading the article that CIDev kindly provided for you.

ZiDoM this is a really wide topic, what CIDev has posted to you is the best answer you can get with this question. Work a little in this and then come and ask more specific things.

Your question is quite vague. However, one possibility would be through the process or thread. On the other hand, it may be using scripting languages, see that page from manual

Communication between processes is a very broad and complex subject. To get started read this article[^].

CIDev gave you a pointer to a great article. However, that article assumes that you know *how* the other program wants to be communicated with.

The bad news for you is that there is no *generic* nor *universal* way for one program to communicate with another. If you want to talk to a "game" and make it do something, you have to at least have the documentation / specification from the "game" developer on exactly what interface they implemented in the "game" that allows it to accept messages from external programs. Once you have that, then you can begin coding your end of that communication. Of course, once you know *how* to pass the messages, you then have to know *what* the message should contain. All of this should be in the documentation of that "game".

Further bad news is that once you figured that out for a "game", the answer for "office" will probably be completely different because it was done by different programmers with a different set of requirements for communication from external programs.

So, it seems you have a lot to research before you know how to start. Sorry for the bad news but it is sadly true that there ain't no single "magic" that will do it all for you.
