usage of Have

[sureshfina]

I have a small doubt in usage of have and having.
When do we use have and having?

When we ask somebody
“Do you have a key with you”
they replies
“Yah I have a key”

But one of my friend asked me “I am having a problem with internet connection, can you come and repair it in the evening?

Please help me to find the difference with examples

Thanks in advance

Here are some examples of BE + having:

having coffee
having a baby
having a party
having dinner
having a drink
having something done for someone
having a bad day

Hopefully more people will write in with additional examples.

I'd put it like this - when have has got something to do with action (in place of an action verb), you can use the progressive; when it comes to a state, you can't use the progressive with have.

I have stomachache. (not I'm having stomachache.)
I'm having dinner. (= I am eating dinner.)
I have a shower in my bathroom. (not I'm having a shower....)
I'm having a shower. (= I'm taking a shower.)

Having something done for someone:

Ex: I'm having a key made for you.

Meaning, I have asked someone to make a key for you.
