AHK Change Nvidia Colour Settings

Question

I want to hotkey nvidia colour profiles. There are sliders on the desktop colour page and I have no idea how to macro these. Can anyone offer any assistance?

What i have gleaned from Window Spy over one of the sliders:

NVIDIA Control Panel
ahk_class
Afx:00007FF7660C0000:b:0000000000010005:0000000000000006:0000000000690523
ahk_exe nvcplui.exe

Control Under Mouse:
ClassNN: msctls_trackbar321
Text:
x: 466 y: 458 w: 188 h: 24
Client: x: 458 y: 407 w: 188 h: 24

Here is the Nvidia Control Panel Page.

Each window Control does have its own ClassNN;

Brightness - ClassNN: msctls_trackbar321
Contrast -ClassNN: msctls_trackbar322
Gamma -ClassNN: msctls_trackbar323

I want to have a few different profiles. so default is (in order of above)

50%, 50%, 1.00

and an example one i want is

60%, 25%, 2.66

The apply button does not have to be pressed for cahnges to take effect

This might not be possible with AHK, may possibly even need some registry editing.
I have no idea how to edit anything in window controls.

It's going to require a significant amount of code. 1. What particular controls do you want to manipulate? 2. Does each of them have its own ClassNN string? If not, it's going to be even more complex. — johnlee

This controls the volume slider in the Volume mixer on my PC

Windows Spy

Volume Mixer - Speakers (Realtek High Definition Audio) ahk_class #32770 ahk_exe SndVol.exe

Below is the control in Spy

ClassNN: msctls_trackbar325 Text:
x: 75 y: 205 w: 43 h: 234 Client: x: 70 y: 172 w: 43 h: 234

This raises the control z = trackbar number 325

Run SndVol.exe WinWaitActive, Volume Mixer - Speakers (Realtek High Definition Audio),, 20

z = 325 ; msctls_trackbar = 325

ControlSend, msctls_trackbar%z%, {Up}, Volume Mixer - Speakers (Realtek High Definition Audio)

You can send a {Down} to lower the control.

You might be able to send a number to the msctls_trackbar and move the slider to a specific position. 0 being bottom 10, 20 30 etc for a position further up the bar.
