 Posted: Thu Nov 08, 2007 10:41 am Post subject: Execute action inside IfWinActive |
 |
|
Hi. I already have a script to alternate between two screen resolutions. What I need is a way to change that resolution when certain window is active, and then change back to the other one when that window is not active (foremost). I tried to define it with IfWinActive, and then inserting a GoSub to call the resolution change code, but to no avail. Any help?
Thanks for your time
EDIT: Sorry, posted in wrong forum  I thought I was doing it in "Ask for Help". Moderator, please move it there. |

show your code with IfWinActive and we can help.
you probably want SetTimer.

I tried, but it's not quite working. The resolution changes to 800x600 even if the program is not active (foremost). Here is the part of the code I'm using:
| Code: | #Persistent
EncodeInteger( p_value, p_size, p_address, p_offset )
{
loop, %p_size%
DllCall( "RtlFillMemory"
, "uint", p_address+p_offset+A_Index-1
, "uint", 1
, "uchar", ( p_value >> ( 8*( A_Index-1 ) ) ) & 0xFF )
}
SetTimer, reschange, 100, Period, 1000
return
reschange:
#IfWinActive, ahk_class ui60
{
colorDepth = 32 ; bits (quality)
screenWidth = 800 ; pixels
screenHeight = 600 ; pixels
refreshRate = 60 ; Hz (frequency)
; Don't change anything below!
struct_devicemode_size = 156
VarSetCapacity(device_mode, struct_devicemode_size, 0)
EncodeInteger(struct_devicemode_size, 2, &device_mode, 36)
success := DllCall("EnumDisplaySettings", "uint", 0, "uint", -1, "uint", &device_mode)
; DM_BITSPERPEL|DM_PELSWIDTH|DM_PELSHEIGHT|DM_DISPLAYFREQUENCY
EncodeInteger(0x00040000|0x00080000|0x00100000|0x00400000, 4, &device_mode, 40)
EncodeInteger(colorDepth, 4, &device_mode, 104)
EncodeInteger(screenWidth, 4, &device_mode, 108)
EncodeInteger(screenHeight, 4, &device_mode, 112)
EncodeInteger(refreshRate, 4, &device_mode, 120)
DllCall("ChangeDisplaySettings", "uint", &device_mode, "uint", 0)
}
return
#IfWinActive

| You need to use IfWinActive , not #IfWinActive. The former is for executable parts of code, the latter is for hotkey definitions. |

and also, your SetTimer has too many parameters - remove the last two.

Finally did it! This script now changes the resolution to 800x600 when the program is active, and switches back to 1280x1024 when it is not!
Thank you all for your suggestions.
