Extracting control buttons from .msstyle

Windows created by Windows have so-called control buttons. These buttons mean "minimize", "maximize", "restore", "close". These buttons can be found in .msstyle files under the path DWMWindow > Common Properties.

MSStyle Editor

The current .msstyle file can be found by using the registry editor at the path HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ThemeManager and accessing the DllName value.

Regedit

In C++, you can open a .msstyle file like this (Taken from How to create control buttons exactly like Window's (OS) control buttons in wxWidgets?):

HINSTANCE handle = LoadLibraryEx(L"C:\\Windows\\Resources\\Themes\\aero\\aero.msstyles",
                                     0, LOAD_LIBRARY_AS_DATAFILE);

HTHEME theme = OpenThemeData(reinterpret_cast<HWND>(this->GetHandle()),L"DWMWindow");

Is it possible to "pull" icons from a given file, but using the python programming language?

I will be glad to any answer!

For the given question, you could look into the PyWin32 library

The library seems to contain within it an OpenThemeData function

The library also seems to contain a LoadLibraryEx function

The usage of a different example is here as well

dllHandle = win32api.LoadLibraryEx(
    dllName, 0, win32con.LOAD_LIBRARY_AS_DATAFILE
)
try:
    data = win32api.FormatMessageW(
        win32con.FORMAT_MESSAGE_FROM_HMODULE,
        dllHandle,
        eventLogRecord.EventID,
        langid,
        eventLogRecord.StringInserts,
    )
finally:
    win32api.FreeLibrary(dllHandle)

It also seems to support the popular winxptheme library

Code inspired from

        # Get the size of a small close button (themed)
hwnd = self.win.GetHandle()
theme1 = winxptheme.OpenThemeData(hwnd, "Window")

Based on both of these, I think the work to combine both should be relatively easy
