TF_CreateLangBarItemMgr function

The TF_CreateLangBarItemMgr function is used to create a language bar item manager object without having to initialize COM. Usage of this method is not recommended, because the calling process must maintain a proper reference count on an object that is owned by Msctf.dll.

It is instead recommended that language bar item manager objects be created using CoCreateInstance , as demonstrated in ITfLangBarItemMgr.

Syntax


HRESULT TF_CreateLangBarItemMgr(
  _Out_  ITfLangBarItemMgr **pplbim
);

Parameters

pplbim [out]

Pointer to an ITfLangBarItemMgr interface pointer that receives the language bar item manager object.

Return value

ValueMeaning
S_OKThe function was successful.
E_FAILAn unspecified error occurred.
E_INVALIDARGpplbim is invalid.

 

Examples

There is no import library available that defines this function, so it is necessary to manually obtain a pointer to this function using LoadLibrary and GetProcAddress. The following code example demonstrates how to accomplish this.

Note  

Using LoadLibrary incorrectly can compromise the security of your application by loading the wrong DLL. Refer to the LoadLibrary documentation for information on how to correctly load DLLs with different versions of Windows.



typedef HRESULT (WINAPI *PTF_CREATELANGBARITEMMGR)(ITfLangBarItemMgr**);

HMODULE hMSCTF = LoadLibrary(TEXT("msctf.dll"));

if(hMSCTF == NULL)
{
    //Error loading module -- fail as securely as possible 
}

else
{
    PTF_CREATELANGBARITEMMGR pfnCreateLangBarItemMgr;
    
    pfnCreateLangBarItemMgr = (PTF_CREATELANGBARITEMMGR)GetProcAddress(hMSCTF, "TF_CreateLangBarItemMgr");

    if(pfnCreateLangBarItemMgr)
    {
        HRESULT hr;
        ITfLangBarItemMgr *pLangBarItemMgr;

        hr = (*pfnCreateLangBarItemMgr)(&pLangBarItemMgr);
        if(SUCCEEDED(hr))
        {
            pLangBarItemMgr->Release();
        }
    }

    FreeLibrary(hMSCTF);
}
