I've seen this question asked before, and as far as I know, you cannot do it (at least in user mode) in 32 bit Windows. I believe it was possible in the 16-bit days.
So, you'd probably have to go the kernel route and try some undocumented stuff.
Alternatively, you could hook the hooker - SetWindowsHookEx, when Windows starts.

I've seen shareware apps claiming they can detect window hooks, but I have yet to find a free one. Nor do they provide any technical detail on how it is done (trade secrets  ).

That won't help me much, as I'm trying to detect what's messing up my keyboard input. I know (from dabbling with hooks myself), that it is easy to screw up the keyboard handling, if you do not pass all messages to the next hook on the chain. I remember failing to forward "peeks" to the next chain, which caused the accelerator translation to fail in some instances, depending on key up/down sequences in n-key combinations. The symptoms I'm witnessing right now matches such bad hook behaviour. The only problem is that I have no hooks installed on this machine...

Do any of them work?

Well, if you hook it, you'll at least know what program it is that's putting a silent hook without your knowledge.

One of them appeared to work, as far as I could tell.

How, exactly...?

I think I wasn't clear in my original post. I meant an API hook on SetWindowsHookEx . The 3rd parameter to SetWindowsHookEx is an HINSTANCE to the DLL where the hook procedure is located. So if you have an API hook on SetWindowsHookEx, you can locate those DLLs (and possibly the parent exes too) that attempt to set a hook.

this will only work if you somehow manage to patch SetWindowsHook for every running process...
the information you require is only available in kernel-mode. You will need a driver to access it. Under the current PEB structure for a process is a pointer to the PDESKTOP kernel object. Under this there is a linked-list of further difficult-to-understand kernel structures, some of which contain info about hooks and the DLLs that they belong to.
You need WinDbg+Symbols+lots of patience

Hellow,
the type of Key is "int". can someone help?
|
|
|
|

i don't know about CMap ; i tried to use it when i designed the 1st version of VisualCalc but came back to the old standars C++ std::map<>.
if it is like the standard map, the map is already sorted by the "key".

thanks,i will have a test on CMap.

I got the result. it seems it is sorted by the time when item was put in.

Great!
But toxccts advice still stands: Stop using CMap and use std::map
CMap is Microsoft proprietary and is the legacy of a time when Microsofts C++ compiler was too braindead to cope with a STL. And when the STL itself was still in the process of definition.

Hi there,
Because of a post on the wrong forum i have to write this again...
I have to display a page in a little webbrowser on my dialog app and want to display the webpage background in the same color as the dialog background.
How can I get the Windows Standard Dialog Background color?
thx in advance
best regards
Michael

if you're talking about your windows configuration, this would better be placed into the OS/Admin forum than into a pure programming forum. anyway, i will not spam CP much than it is already.
you go there :
Start Menu > Control Panel > Display , Appearence Tab > Advanced Button.
there, under each category, you have one or more colors, which you can click on...
if it is not what you asked for, please reformulate with more details about what you have, what you need and what you do...
thx

You can use GetSysColor with COLOR_BTNFACE.

@toxcct <ironie>thx for the very helpful post. here we have of corse a windows forum and not a visual C++ forum 
I know but this doesn't work.
CString rgbcolors;
rgbcolors.Format("%d,%d,%d", GetRValue(COLOR_BTNFACE), GetGValue(COLOR_BTNFACE), GetBValue(COLOR_BTNFACE));
rgbcolors returns "15,0,0"
And thats black not the dialog gray. 
|
|
|
|
|
ow, that was my mistake...
now it works...
COLORREF col = GetSysColor(COLOR_BTNFACE);
CString rgbcolors;
rgbcolors.Format("%d,%d,%d",GetRValue(col),GetGValue(col),GetBValue(col));
|
|
|
|
|
Do this :-
DWORD color = GetSysColor(COLOR_BTNFACE);
cout << (int)GetRValue(color);
cout << (int)GetGValue(color);
cout << (int)GetBValue(color);

Nish
