AHK to simulate ctrl + alt + break to exit remote desktop full screen mode [closed]

Question

I want to use AHK to simulate Ctrl + Alt + break.

The below code does nothing. I have also pasted the key history with first using the Num - and then actually pressing the set of trio keys. The AHK key doesn't work while the actual pressing of key works. The codes generated by both appear to be same to me except that Break has d & u with AHK. But that shouldn't matter. I also introduced the delay but that also doesn't work.

SetKeyDelay, 2,2
NumpadSub::
send {LCtrl Down}{LAlt Down}{vk03sc146}{LCtrl Up}{LAlt Up}
return  

I also tried with {CtrlBreak} and the below with no success in Win XP remote desktop. send !^{vk03sc146} This code works find in my win 7. However I need to remote in to the Win XP. Help please.

6D  04A     d   1.33    Num -           
A2  01D i   d   0.00    Ctrl            
A4  038 i   d   0.02    Alt             
03  146 i   d   0.02    Break           
03  146 i   u   0.02    Break           
A2  01D i   u   0.02    Ctrl            
A4  038 i   u   0.02    Alt             
6D  04A     u   0.16    Num -

Answer 1

It is possible to capture the CapsLock key from AHK even if it was started before RDP, it is the ONLY key that RDP passes on to other keyboard hooks.

This can be done on the local machine. When you do it on the local machine, and NOT on the remote machine, you can use AHK to obtain the window id of MSTSC, and pass a restore command to the window (no sending of keys, which is terribly unreliable)

;Get MSTSC window (this may have to be "ahk_class TSSHELLWND" for systems other than Win7)
If WinActive("ahk_class TscShellContainerClass") {
    WinGet, active_id, ID, A
    PostMessage, 0x112, 0xF120,,, ahk_id %active_id%   ; 0x112 = WM_SYSCOMMAND, 0xF120 = SC_RESTORE
}

The above command will break MSTSC from fullscreen.

A full example of this can be seen here (http://code.ecomerc.com/Articles/RotateCube/), where it is used to break MSTSC from fullscreen and rotate the cube function of Dexpot (a 3d window manager)

All credits to Peter's answer above, which is the only working solution so far after a hour search. I slightly modified it to make it only slightly more complete.

This AHK script allows using alt + capslock to exit full screen mode and then when the remote desktop window is selected, press the alt + capslock again to restore full screen. Start the AHK script on the host machine.

;Get MSTSC window (this may have to be "ahk_class TSSHELLWND" for systems other than Win7)
!Capslock::
T := !T
If WinActive("ahk_class TscShellContainerClass") {
    WinGet, active_id, ID, A
    if T
        PostMessage, 0x112, 0xF120,,, ahk_id %active_id%   ; 0x112 = WM_SYSCOMMAND, 0xF120 = SC_RESTORE
    else
        PostMessage, 0x112, 0xF030,,, ahk_id %active_id%   ; 0x112 = WM_SYSCOMMAND, 0xF030 = SC_MAXIMIZE
}
return
