Properti IAppHostSectionDefinition::OverrideModeDefault

Mendapatkan atau mengatur perilaku penimpaan default untuk bagian konfigurasi saat ini.

Sintaks

HRESULT get_OverrideModeDefault(  
   [out,  
   retval] BSTR* pbstrOverrideModeDefault  
);  
HRESULT put_OverrideModeDefault(  
   BSTR bstrOverrideModeDefault  
);   

Parameter

pbstrOverrideModeDefault
Penunjuk ke yang BSTR menunjukkan perilaku penimpaan default. Nilai yang valid adalah "Izinkan" dan "Tolak".

bstrOverrideModeDefault
BSTR yang menunjukkan perilaku penimpaan default. Nilai yang valid adalah "Izinkan" dan "Tolak".

Tampilkan Nilai

Sebuah HRESULT. Nilai yang mungkin termasuk, tetapi tidak terbatas pada, yang ada dalam tabel berikut.

Nilai	Deskripsi
S_OK	Menunjukkan bahwa operasi berhasil.

Keterangan

Jika Anda tidak secara eksplisit mengatur nilai properti ini, defaultnya adalah "Izinkan". "Izinkan" menentukan bahwa pengaturan dapat ditimpa dalam tingkat konfigurasi yang lebih rendah; "Tolak" menentukan bahwa pengaturan tidak dapat ditimpa.

Deskripsi

Contoh kode berikut membuat grup bagian baru dan bagian baru, lalu mengatur OverrideModeDefault nilai properti dari bagian yang baru dibuat ke "Tolak".
