SendKeys is not an option.

It is almost not possible if SendKeys is not an option but read more

Now more important part of the question- why:

We have to look how win32 application works: it has a WndProc/WindowProc method which is resposible for processing "events" form the UI. So every event in the windows application must go through above method. SendKeys method is a special of SendMessage (MSDN), so you can use SendMessage to control other exe than your.

Simple code could look like:

IntPtr hwnd = FindWindow("Notepad++", null);
SendMessageA(hwnd, WM_COMMAND, SOMETHING1, SOMETHING2);

There is already on StackOverflow example how to do that with chrome: C# - Sending messages to Google Chrome from C# application , but this is only a start. You will have to find out what exactly message you want to send.

In exactly situation which you described I will try to send WM_MOUSE and WM_KEYBORD events to Notepad++ events, but it is only an idea :)
