Regarding ShellExecuteEx behavior in Windows 8

Hi,

The code below for file with no-extension brings up a dialog shown below listing applications that can be used to open the file. This behavior is seen only from Windows-8. For platforms less than windows 8, you get ERROR_NO_ASSOCATION error. And the applications listed in the dialog are taken from HKEY_LOCAL_MACHINE\SOFTWARE\Classes\*\OpenWithList. Is there anyway to suppress this dialog and get a behavior similar to old platforms?

SHELLEXECUTEINFO shinfo;
unsigned long  mask = SEE_MASK_FLAG_NO_UI;
memset(&shinfo,0,sizeof(shinfo));
shinfo.cbSize = sizeof(shinfo);
shinfo.fMask = SEE_MASK_FLAG_DDEWAIT | mask;
shinfo.hwnd = NULL;
shinfo.lpVerb = "open";
shinfo.lpFile = prog;
shinfo.lpParameters = NULL;
shinfo.lpDirectory = 0;
shinfo.fMask = SEE_MASK_FLAG_NO_UI;
shinfo.nShow = SW_SHOWDEFAULT;

rc = ShellExecuteEx(&shinfo);
