SendMessage

[PaulDG]

I am trying to send this msg via a dll call

::SendMessage(HWND_BROADCAST ,
        WM_SETTINGCHANGE,SPI_SETNONCLIENTMETRICS,NULL);

I've read through the forums and found some similar stuff but nothing seems to work. i have this so far

DLLCall("user32.dll","int","SendMessage","hwnd","HWND_BROADCAST","int", "WM_SETTINGCHANGE", "int", "SPI_SETNONCLIENTMETRICS", "int", "NULL")

Any Ideas?

Many Thanks

Did you replace "HWND_BROADCAST", "WM_SETTINGCHANGE", and "SPI_SETNONCLIENTMETRICS" with the correct parameters? Caus I think these are only placeholders...

[PaulDG]

No i did not :">

How do i go about finding them out?

[Raindancer]

I'm not sure how... never did before...

Where did you find this DLLCall, maybe there are lists... usually the parameters are hexadecimal values, or structs (DLLStruct)...

Lifted from various Google results:

Public Const HWND_BROADCAST As Long = &HFFFF& (I believe to be equivalent to 0xffff)

0x1A is WM_SETTINGCHANGE

Public Const SPI_SETNONCLIENTMETRICS As Long = &H2A (probably = 0x2a)

Hope this helps!

Thems the ones

$result = DLLCall("user32.dll","int","SendMessage","long","0xffff", "long", "0x1a", "long", "0x2a")

Thanks Both of you very much.

[Raindancer]

Now you got to tell us what it does...

[LxP]

$result = DLLCall("user32.dll","int","SendMessage","long","0xffff", "long", "0x1a", "long", "0x2a")

I'm not entirely confident that that will work for you as expected (given the hex notation). You may wish to try it without the quotes around the numbers:

dllCall("user32.dll", "int", "SendMessage", "long", 0xffff, "long", 0x1a, "long", 0x2a)

It works Perfectly, I guess it will work just as good without the quotes

If you change a value (any valude) in the winmetrics section of the registry like iconsize then run that command then change the value back again and run that command again it will cause a complete icon cache flush, including the disk and memory cache.

What good is that, well if you want to change the icon for your folders (globally) then you can set a new icon in the registry and when you perform the above the cache will be rebuilt with your new icon instead of the drab yellow one. you can replace any icon in shell32.dll this way, without editing your actual file.

Microsoft says this is not posible, but i assure you it is.

2 things,

You can set that registry entry up during windows install at the t13 min stage and you dont need the cache flush then as it isnt built yet.

Don't play with this unless you are prepared to loose all your custom icon positions, as it wipes them out and they all line up neatly against the left hand edge plus i think it resets all the folder view settings but i am not sure.
