Current Release

On The Fly DPI

On The Fly DPI allows you change the mouse sensitivity on the fly (very quickly) by using modifier keys (hotkeys) and the mouse. ONFDPI is stand-alone application that can be used for anything that would call for changing the sensitivity quickly such as gaming (far to near sniping anyone?) or graphic design or whatever else you might think of.

Usage

ONFDPI runs in the system tray where there’s a help selection with the listed hotkeys and other info and selections to restart and exit the program.

Hotkeys (not perfected yet, but I think they’re suitable for now)

Raise Sensitivity: Mouse Wheel Up Or XButton2
[Control]+[Alt]+	+1 Sensitivity
[Control]+[Shift]+	+2 Sensitivity
[Shift]+[Alt]+		Max Sensitivity

Lower Sensitivity: Mouse Wheel Down Or XButton1
[Control]+[Alt]+	-1 Sensitivity
[Control]+[Shift]+	-2 Sensitivity
[Shift]+[Alt]+		Min Sensitivity

Default: Click Mouse Button
[Control]+[Alt]+	Reset to default

Example Code - Function I wrote to get and set the mouse dpi (1-20, 10 being default)

MouseDpi(mode_speed:=0){ 
	DllCall("SystemParametersInfo","UInt",0x70,"UInt",0,"UIntP",_current_,"UInt",0)
	If mode_speed Is Not Number
		{
			If (InStr(mode_speed,"reset") And (_current_!=10)){
				DllCall("SystemParametersInfo","UInt",0x71,"UInt",0,"UInt",10,"UInt",0)
				DllCall("SystemParametersInfo","UInt",0x70,"UInt",0,"UIntP",_current_,"UInt",0)
			}
			Return _current_
		}
	mode_speed	:=(mode_speed!=0 And mode_speed>20)?20
				:(mode_speed!=0 And mode_speed<0)?1
				:mode_speed
	If (mode_speed!=0 And (_current_!=mode_speed))
		DllCall("SystemParametersInfo","UInt",0x71,"UInt",0,"UInt",mode_speed,"UInt",0)
	Return !mode_speed?_current_:mode_speed
}

Setting DPI - Increase current dpi + 1

MouseDpi(MouseDpi()+1)

Motivation

I always need to change the mouse sensitivity quickly and I have used scripts for a while, but I wanted something small and portable.

Installation

Portable program (Plans for installer and portable option).

Test

I have tested on Windows 10 64 bit.
