EnumEnabledLayoutOrTip function

Enumerates all enabled keyboard layouts or text services of the specified user setting.

Syntax

UINT EnumEnabledLayoutOrTip(
  _In_opt_ LPCWSTR            pszUserReg,
  _In_opt_ LPCWSTR            pszSystemReg,
  _In_opt_ LPCWSTR            pszSoftwareReg,
  _Out_    LAYOUTORTIPPROFILE *pLayoutOrTipProfile,
  _In_     UINT               uBufLength
);

Parameters

pszUserReg [in, optional]

The registry path of the user. If this parameter is NULL, HKEY_CURRENT_USER is used.

pszSystemReg [in, optional]

The registry path of the system. If this parameter is NULL, HKEY_LOCAL_MACHINE\System is used.

pszSoftwareReg [in, optional]

The registry path of the software. If this parameter is NULL, HKEY_LOCAL_MACHINE\Software is used.

pLayoutOrTipProfile [out]

Pointer to the buffer that receives the LAYOUTORTIPPROFILE array.

uBufLength [in]

The length of the buffer pointed to by pLayoutOrTipProfile.

Return value

If pLayoutOrTipProfile is NULL, the number of keyboard items that are enabled in the user setting; otherwise, the number of keyboard items that are copied into pLayoutOrTipProfile.

For Input Method Editor (IME) languages, all IMEs are returned, even when only one IME is enabled. For example, if a user has the CHT New Quick IME enabled, the EnumEnabledLayoutOrTip function returns all 5 CHT IMEs.

Note

Using LoadLibrary incorrectly can compromise the security of your application by loading the wrong DLL. Refer to Dynamic-Link Library Search Order for information on how to correctly load DLLs with different versions of Microsoft Windows.
