Send Characters from OSK to NotePad using Autoit

[Ronster]

I would like to create an auto login program using mouseclicks, controlclicks only, or whatever is required to send characters from Windows 10 On-Screen Keyboard to a User/Password login form. I thought I would start with OSK to NotePad. Using mouseclicks to enter ID/Password seems more secure than typing plain text. Seems like if I can get that to work I should be able to send the characters to any login form. I have tried many things but cannot send a character(s) from OSK to Notepad. Of course manually works great. Here is some code I have tried:

ControlGetFocus ("Untitled - Notepad")
    ; go to Notepad window
    MouseMove(649, 206 , 0)  ;move to Notepad, then click below
    Sleep (1000)
    MouseClick($MOUSE_CLICK_LEFT,"left")

    ControlGetFocus ("On-Screen Keyboard")
    ; go to OSK window then click on a character key
    MouseMove(642, 807 , 0) ;letter - t
    Sleep (1000)
    MouseClick($MOUSE_CLICK_LEFT,"left")

OR

ControlClick("On-Screen Keyboard","","[CLASS:OSKMainClass]","left","",642, 807)

The above move to the correct position and appear to click but focus is lost to Notepad. Any help would be appreciated.

Instead of using Mouse* functions, you could directly use ControlSetText()
