In C run-time libs is there a function that renurns if the given string is a directory or a file name?

I'm quite sure of the opposite, now. Blush | :O

I've to admit, I erroneously read 'path' as 'name' (i.e. more caffeine is needed this morning)

If you can use Win32, GetFileAttributes() will do that for you nicely:

you can change access of usb device through registry.
Registry path
[code]
LOCAL_MACHINE, "SYSTEM\\CurrentControlSet\\Control\\StorageDevicePolicies"
[/code]
just you change the values
[code]
"0" to "1"
WriteProtect="1"
[/code]

Are you of the thinking that code cannot be used to manipulate the registry?

How to find the language installed or Language package exists or language in OS will support or not?
I failed to use GetUILanguage and EnumUILangauges API's. Any suggestions?

. If you can help me on how to use this API it will be very useful for myself.

Here goes -

BOOL CALLBACK EnumUILanguagesProc(
  LPTSTR lpUILanguageString, 
  LONG_PTR lParam
)
{
   MessageBox(0, lpUILanguageString, 0, 0);
   return TRUE;
}

int main()
{
   EnumUILanguages(EnumUILanguagesProc, MUI_LANGUAGE_NAME, 0);
}

If you want the language id instead of the language name, replace MUI_LANGUAGE_NAME with MUI_LANGUAGE_ID.

To check if the operating system supports the language I believe that you can just call the IsValidLanguageGroup Function[^]

Such as:

BOOL bSupported = IsValidLanguageGroup(LGRPID_INDIC,LGRPID_SUPPORTED);
BOOL bInstalled = IsValidLanguageGroup(LGRPID_INDIC,LGRPID_INSTALLED);

Best Wishes.

IsValidLanguageGroup(LGRPID_SIMPLIFIED_CHINESE | LGRPID_TRADITIONAL_CHINESE, LGRPID_INSTALLED);

is returning false when i tried in Windows XP Chinese, but it is returning true in English OS where East Asian language pack installed
