Note

The following identifiers are not defined in a public header file. You must either use the hexadecimal value or #define the identifiers. For example, to use ILOT_UNINSTALL you must include #define ILOT_UNINSTALL 0x00000001 in your code.

Value	Meaning
ILOT_UNINSTALL 0x00000001	Same as ILOT_DISABLED.
ILOT_DEFPROFILE 0x00000002	Sets the specified layout or tip as a default item.
ILOT_DEFUSER4 0x00000004	Changes the setting of .Default.
ILOT_SYSLOCALE 0x00000008	Unused.
ILOT_NOLOCALETOENUMERATE 0x00000010	Unused.
ILOT_NOAPPLYTOCURRENTSESSION 0x00000020	The setting is saved but is not applied to the current session.
ILOT_CLEANINSTALL 0x00000040	Disables all of the current keyboard layouts and text services.
ILOT_DISABLED 0x00000080	Disables the specified keyboard layout and text service.

Return value

Remarks

The string format of the layout list is:

<LangID 1>:<KLID 1>;[...<LangID N>:<KLID N>

The string format of the text service profile list is:

<LangID 1>:{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx};

The following is an example of a value for the psz parameter:

"0x0407:0x00000407"
"0x0407:0x00000407;0x040C:0x0000040C"
"0x0407:0x00000407;0x0412:{A028AE76-01B1-46C2-99C4-ACD9858AE02F}{B5FE1F02-D5F2-4445-9C03-C568F23C99A1};0x040C:0x0000040C"

Examples

There is no import library available that defines this function, so it is necessary to obtain a pointer to this function using LoadLibrary and GetProcAddress.

typedef HRESULT (WINAPI *PTF_ INSTALLLAYOUTORTIP)(LPCWSTR psz, DWORD dwFlasg);

HMODULE hInputDLL = LoadLibrary(TEXT("input.dll"));
BOOL bRet = FALSE;

if(hInputDLL == NULL)
{
    // Error loading module; fail as securely as possible. 
}
else
{
    PTF_ INSTALLLAYOUTORTIP pfnInstallLayoutOrTip;
    
    pfnInstallLayoutOrTip = (PTF_ INSTALLLAYOUTORTIP)GetProcAddress(hInputDLL, "InstallLayoutOrTip");

    if(pfnInstallLayoutOrTip)
    {
        bRet = (*pfnInstallLayoutOrTip)(psz, dwFlags);
    }

    FreeLibrary(hInputDLL);
}
