Redraw Desktop

i'm using this script to remove the internet explorer symbol from the desktop (it's not a standard .lnk).

WriteRegDWORD HKCU "Software\Microsoft\Windows\CurrentVersion\Explorer\HideDesktopIcons\ClassicStartMenu" "{871C5380-42A0-1069-A2EA-08002B30309D}" "1"

System::Call 'user32.dll::GetDesktopWindow(v) i .r0'

SendMessage $0 ${WM_SETREDRAW} 1 0

however, the desktop does not get redrawn. only when i press f5 the ie symbol disappears. any clue where the bug is in my code?

Try calling UpdateWindow.

using this, still no result

System::Call 'user32.dll::GetDesktopWindow(v) i .r0'

System::Call 'user32.dll::UpdateWindow(i r0) v r1'

Use NULL window handle
(C) RedrawWindow(NULL, NULL, NULL, RDW_INVALIDATE | RDW_ERASE);

Not works 🙁
But I found in my old progs how I added hook to desktop listview, following code gets it handle

System::Call 'user32.dll::FindWindowEx(i 0, i 0, t "Progman", i 0) i .r0'

System::Call 'user32.dll::FindWindowEx(i r0, i 0, t "SHELLDLL_DefView", i 0) i .r0'

System::Call 'user32.dll::FindWindowEx(i r0, i 0, t "SysListView32", i 0) i .r0'

Yathosho:

System::Call 'shell32::SHChangeNotify(i, i, i, i) v (0x08000000, 0, 0, 0)'

Takhir:

!define WM_KEYDOWN 0x0100

!define VK_F5      0x74



FindWindow $0 "Progman"

FindWindow $0 "SHELLDLL_DefView" "" $0 0

FindWindow $0 "SysListView32" "" $0 0

SendMessage $0 ${WM_KEYDOWN} ${VK_F5} 0

I try this too, but "0x0100" isn't correct interpreted (most probably as "0x01")

System::Call 'shell32::SHChangeNotify(i, i, i, i) v (0x08000000, 0, 0, 0)'

this alone works, thanks. however, so i can understand this better i have another question. which part of the call addresses the desktop (is it 0x08000000)? can i use the call to redraw other parts, i.e. the start-menu?

0x08000000 is the SHCNE_ASSOCCHANGED flag (from here) and it's essentially forcing the OS to force update the icon cache and re-check any items which should be shown

i was asking, cause i also plan on changing the startmenu to "classic mode" and change some explorer settings (detail view, show file extensions, etc.). i'd make those changes by changing registry-entries. is any of the above mentioned calls able to apply these settings, so the user does not have to reboot?

this alone works, thanks.

is there something like this to remove the IE icon from the quick launch too

The icon should be in the $QUICKLAUNCH folder.

i.e.
C:\Documents and Settings\[user_account]\Application Data\Microsoft\Internet Explorer\Quick Launch

the problem is, that the icon gets deleted, but still remains in the quicklaunch until i crash+reload the explorer or reboot windows

Can anybody help me with a code to refresh the tray area? When I kill a process it's icon is still present in the tray. I want it to disappear by refresh the tray. Is there a code for this ?

yeah, how about a plugin to redraw several parts of windows? 🙂

I've searched Google and they all say you have to use Shell_NotifyIcon to delete the tray icon by its handle.

sorry for the late response, forgot about this since my trip to london.

i was speaking of the quicklaunch, not the tray. this summed up pretty well what i was looking for 😛
