Sintaks

C#

int GetResolutionInfo( 
    enum_BPERESI_FIELDS        dwFields,
    BP_ERROR_RESOLUTION_INFO[] pErrorResolutionInfo
);

C++

HRESULT GetResolutionInfo( 
    BPERESI_FIELDS            dwFields,
    BP_ERROR_RESOLUTION_INFO* pErrorResolutionInfo
);

Parameter

dwFields
[di] Kombinasi bendera dari enumerasi BPERESI_FIELDS yang menentukan bidang pErrorResolutionInfo mana yang akan diisi.

pErrorResolutionInfo
[masuk, keluar] Struktur BP_ERROR_RESOLUTION_INFO yang diisi dengan deskripsi resolusi titik henti.

Tampilkan Nilai

Jika berhasil, mengembalikan S_OK; jika tidak, mengembalikan kode galat.
