In Windows 10 ICC_LINK_CLASS & WC_LINK classes are not found

NTDEV

I am creating a shell extension. In my property sheet dialog, I have a added a “SysLinK Control”. But as soon I add this control my dialog doesn’t come.

I tried programmatically create this control using

HWND hwnd = CreateWindowEx(0, WC_LINK,L"Ajesh",
WS_VISIBLE | WS_CHILD | WS_TABSTOP,
7, 254, 178, 10,
m_hDlg, NULL, g_hInstRes, NULL);

But it fails with error code 1407 i.e Cannot find window class.

I also tried intialize common control using

INITCOMMONCONTROLSEX iccex;
iccex.dwSize = sizeof(INITCOMMONCONTROLSEX);
iccex.dwICC = ICC_LINK_CLASS;
BOOL bret = InitCommonControlsEx(&iccex);

But it also fails to initialize for ICC_LINK_CLASS.

For Windows 10, Is there is any change “SysLinK Control” ? I cant find any documentation with any change information.

Thanks for the help

WC_LINK work in Windows 10

Is there something which I am missing in my code? Any idea why i am getting such error in my code?

hard to say. code like this -
CreateWindowEx(0, WC_LINK,L"Ajesh",
WS_VISIBLE | WS_CHILD | WS_TABSTOP,
7, 254, 178, 20, hwnd, 0, 0, 0);
must create child window. if not - i be research this under debugger - where exactly fail. for example my trace (when control successful created) - https://imagizer.imageshack.us/v2/1803x943q90/538/Uiokcb.png

or even better, if this code fail
INITCOMMONCONTROLSEX iccex = {sizeof(INITCOMMONCONTROLSEX), ICC_LINK_CLASS };
InitCommonControlsEx(&iccex);
trace it under debugger
INITCOMMONCONTROLSEX iccex = {sizeof(INITCOMMONCONTROLSEX), ICC_LINK_CLASS };
InitCommonControlsEx(&iccex);

I am using a shell extension code from MSDN https://code.msdn.microsoft.com/windowsdesktop/CppShellExtPropSheetHandler-d93b49b7/sourcecode?fileId=21961&pathId=81239272

As soon I add a SYSLINK object, I see the above failure.

Is there some reason that I’m missing that this has been posted to NTDEV? Isn’t this a COM question?

If you disassemble InitCommonControlEx, you’ll see that it fails if
either ICC_STANDARD_CLASSES or ICC_LINK_CLASS is set. There’s no other
conditions that make it pass: if any bits outside of the low-order 14
are set, instant fail.

That’s a pretty serious problem.
