Is there a way to run a macro in a inactive window?

[Narak13]

There is no reliable way to send keys to an inactive window, unless using a virtual machine.
Try function SendKeysToWindow from this topic:

I appreciate your quick answer Gintaras. Unfortunately I tried this method and didn't work out, at least not with this app but fortunately I already found another alternative, i'm gonna use my old PC for that.

But thanks for your answer, i'm gonna use this function anyway, it helped me with another macros.
