[Search] unknown system call

[Brummelchen]

we have a little problem...

anyony knows tweaking tools like TuneUp or TweakUI

now we have this entry

REGEDIT4

[HKEY_CURRENT_USER\Control Panel\Desktop]
"MenuShowDelay"="8"

(this speeds up the menu open)

it is very simple to write a script for it, but unfortunately system does not take this value - only after restart.
but tweaking tools do so w/o system restart

so i suppose an unknown system call to establish those values

pls help

You probably need to send WM_WININICHANGE. Try:

SendMessage ${HWND_BROADCAST} ${WM_WININICHANGE} 0 "STR:Control Panel"
/TIMEOUT=5000

sorry for bringing up confusion in my previous post. it should work when you use

SendMessage ${HWND_BROADCAST} ${WM_WININICHANGE} 0 "STR:MenuShowDelay" /TIMEOUT=500

[Brummelchen]

nothing :/

code:
;--------------------------------

;Configuration



!define PRODUCT "MenuShowDelay"

!define VERSION "1.0"



Name "'${PRODUCT}'"



Caption "MenuShowDelay 1.0"

OutFile "MenuShowDelay.exe"



!include WinMessages.nsh

  ReadINIStr $R0 "$EXEDIR\MenuShowDelay.ini" MenuShowDelay MenuShowDelay

  WriteRegStr HKCU "Control Panel\Desktop" "MenuShowDelay" $R0

  SendMessage ${HWND_BROADCAST} ${WM_WININICHANGE} 0 "STR:MenuShowDelay" /TIMEOUT=500

  Quit

FunctionEnd

i'm sorry. by trying to take back the confusion of my previous post, i created some more confusion. doesn't work indeed

SendMessage(HWND_BROADCAST, WM_SETTINGCHANGE, 0, (LPARAM) (LPCTSTR)"MenuShowDelay");

this is what i got from MSDN, but WM_SETTINGCHANGE is not supported by NSIS

[Brummelchen]

never mind, was just a try.

the damned nview desktop manager resets on startup the delay to 400 and i tried to help my friend...

thx 4all

[Yathosho]

still i'd love to see a solution

[Joost Verburg]

WM_SETTINGCHANGE is identical to WM_WININICHANGE.

[Brummelchen]

[Joost Verburg]

As I already said, WM_WININICHANGE is the same. But I've added WM_SETTINGCHANGE so you can also use the modern name.

[Yathosho]

guess that's why it still doesn't work

[Yathosho]

would it be possible to do the same by commandline (rundll or anything like that)? does anybody know about such stuff?

Try this:

code:


!define PRODUCT "MenuShowDelay"

!define VERSION "1.0"



Name "'${PRODUCT}'"



Caption "MenuShowDelay 1.0"

OutFile "MenuShowDelay.exe"



!include WinMessages.nsh

!define SPI_SETMENUSHOWDELAY 107

!define SPIF_SENDINICHANGE 3

  MessageBox MB_OK "Done: $R1"

  Pop $R1

  Pop $R0

  Quit

not sure if it's coincidence or if my system went unusuable after trying this. however, i can't tell what made my system unusable and i don't want to claim it was was the script's fault. in any case, i'm now using vmware to test scripts with code i don't understand.

i'd like to know more about this system call. what is SPI_SETMENUSHOWDELAY? is this meant to refresh the MenuDelay setting only? i'd be interested in finding out more about this, since i want to reload other settings from the registry aswell.

[iceman_k]

Its a documented Windows API call- I don't see why it would mess up your system. Look up MSDN documentation on SystemParametersInfo. It is the same call made by TweakUI.
SPI_SETMENUSHOWDELAY is only for MenuDelay. There are a bunch of other settings, they're all in the API documentation.
