 Posted: Wed Aug 10, 2005 8:12 pm Post subject: Refreshing desktop (icons) upon hotkey event |
 |
|
I'm looking for a way to refresh the desktop with AHK, (as when you rightclick on desktop and press 'Refresh' in the context menu). The best thing I've come up with so far is this:
| Code: |
hotkey,!1,Refresh
return
Refresh:
mouseclick, right
sleep 20
send,{ctrl down}u{ctrl up}
return
|
 YES i know, it's very crude and I'm desperate to find another solution that is a bit more fool-proof.
I'm convinced that the answer lies in a Send/Postmessage or a Dllcall(), but I'm unfortunately not very familiar to such commands...  
 The trick is that pressing F5 does not work in my case, but there has to be another way...

Here you go.
| Code: | !1::
Send, {F5}
return
|
Update:
Oh NM, I just realized that you said F5 does not work on your case.
Let me see if there is another way.

Here comes a complicated but working solution 
| Code: | ;Get the current icon size and change it
RegRead, icon_size, HKEY_CURRENT_USER, Control Panel\Desktop\WindowMetrics, Shell Icon Size
icon_size++
;write changes to registry
RegWrite, REG_SZ, HKEY_CURRENT_USER, Control Panel\Desktop\WindowMetrics, Shell Icon Size, %icon_size%
;disables redrawing informs the desktop that there are changes
SendMessage, 0x0B, 0, 0,SysListView321,ahk_class Progman
SendMessage, 0x1A, 0, 10000,SysListView321,ahk_class Progman
;changes icon_size back to the original value
icon_size--
RegWrite, REG_SZ, HKEY_CURRENT_USER, Control Panel\Desktop\WindowMetrics, Shell Icon Size, %icon_size%
;enables redrawing. the desktop will be refreshed
SendMessage, 0x1A,0, 10000,SysListView321,ahk_class Progman
SendMessage, 0x0B, 0, 1,SysListView321,ahk_class Progman
|
So far, I've tested it with XP. It works in most cases but is far from beeing perfectly. |

Thank you all for your replys but in some way neither of your suggestions work!  
What I'm trying to do is to make a script hide/unhide desktop icons:
| Code: |
hotkey,!1,Hide
hotkey,!2,Show
return
Hide:
regwrite, REG_DWORD, HKEY_CURRENT_USER, Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced,HideIcons, 1
SendMessage, 0x1A,,,, Program Manager ;Supposed to update desktop but only updates the icons ;themselves, not checking whether they actally are visible
traytip
traytip, Desktop, Icons Hidden!, 5,1
return
Show:
regwrite, REG_DWORD, HKEY_CURRENT_USER, Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced,HideIcons, 0
SendMessage, 0x1A,,,, Program Manager
traytip
traytip, Desktop, Icons Unhidden!, 5,1
return
|
When I run it and press Alt + 1 the icons does not disappear (until I manually press Refresh).
I have Win2k, AHK version 1.0.37.04
But (the most annoying thing) pressing 'Refresh' works fine...
Sorry guys for disappointing you, "Let's help each other out"

I wrote a similar script to show/hide desktop icons. The problem with using winhide/winshow is that it also hides Rainlendar and the desktop wallpaper, and disables the desktop context menu. Using the registry is better as it only affects the icons.

I agree with Serenity, the only thing I need now is something that refreshes the desktop and its icons. 
Thanks for your replys, guys!

This VB script suggests there is a 'low level' way to refresh the icons.
| Code: | ' Send HWND_BROADCAST to refresh the icons.
SendMessageTimeout HWND_BROADCAST, WM_SETTINGCHANGE, _
SPI_SETNONCLIENTMETRICS, 0&, SMTO_ABORTIFHUNG, _
10000&, result |
From API-Guide:
| Quote: | SPI_GETNONCLIENTMETRICS
Retrieves the metrics associated with the nonclient area of nonminimized windows. The pvParam parameter must point to a NONCLIENTMETRICS structure that receives the information. |
and from MSDN:
| Quote: | To send the WM_SETTINGCHANGE message to all top-level windows, use the SendMessageTimeout function with the hwnd parameter set to HWND_BROADCAST.
If this parameter is HWND_BROADCAST, the message is sent to all top-level windows in the system, including disabled or invisible unowned windows. The function does not return until each window has timed out. |
Perhaps there is some way to use DllCall to send the WM_SETTINGCHANGE message?

This?
| Code: | SendMessage, 0x1A, 42,,, ahk_id 0xFFFF
MsgBox, %errorlevel% |
SendMessage Help:
| Quote: | | To send a message to all windows in the system, including those that are hidden or disabled, specify ahk_id 0xFFFF for WinTitle (0xFFFF is HWND_BROADCAST). This technique should be used only for messages intended to be broadcast, such as the following example: SendMessage, 0x1A,,,, ahk_id 0xFFFF ; 0x1A is WM_SETTINGCHANGE |
Google:
42 = SPI_SETNONCLIENTMETRICS |

No, updates desktop but does not affect the icons state of hidden/visible... | Quote: |

Hi,
I am not sure if this works for you too, but after setting a wallpaper I have found following to be effective to update the desktop.

Try the following:
(tested with Windows XP SP2 [and Rainlendar])
| Code: |
WinGet, hw_program_manager, ID, Program Manager ahk_class Progman
;MsgBox, % hw_program_manager
hw_SHELLDLL_DefView := FindWindowEx( hw_program_manager, 0, "SHELLDLL_DefView", 0 )
;MsgBox, % hw_SHELLDLL_DefView
hw_FolderView := FindWindowEx( hw_SHELLDLL_DefView, 0, "SysListView32", "FolderView" )
;MsgBox, % hw_FolderView
MsgBox, Now you see them ...
WinHide, ahk_id %hw_FolderView%
MsgBox, .. now you dont!
WinShow, ahk_id %hw_FolderView%
return
FindWindowEx( p_hw_parent, p_hw_child, p_class, p_title )
{
if ( p_title = 0 )
type_title = uint
else
type_title = str
return, DllCall( "FindWindowEx"
, "uint", p_hw_parent
, "uint", p_hw_child
, "str", p_class
, type_title, p_title )
}
|
I believe the registry setting change is still required to ensure the state is persistent (not tested). |

@ UweD
This works perfectly for updating the desktop wallpaper! I have been looking for this for hours. Thank you very much!
Just one Q: Because it is accessing System32 directory, do you need Administrator rights?
Thanks again. |

Short answer: just try!
Longer answer: probably not, otherwise your system wouldn't work! You don't do any change in this dir, just access a system file to make it do one job. Windows is doing this all the time! |
