IItemMetadata::TryGetFieldUInt64
Gets the value of a 64-bit unsigned integer field.
Syntax
HRESULT TryGetFieldUInt64(
LPCWSTR pcszFieldName,
ULONGLONG * pValue);
Parameters
pcszFieldName
[in, string] The name of the field.pValue
[out] Returns the value of the specified field.
Return Value
S_OK
S_FALSE if the value has not been set.
E_POINTER
E_INVALIDARG
SYNC_E_METADATA_FIELD_INVALID_NAME if the field does not exist.
SYNC_E_METADATA_FIELD_INVALID_TYPE if the field is not a 64-bit unsigned integer.
Remarks
Custom fields must be defined by using a CUSTOM_FIELD_DEFINITION structure when the replica metadata is first initialized.
If IItemMetadata::SetFieldUInt64 was called to set the field value, but the change has not yet been saved by a call to IReplicaMetadata::SaveItemMetadata, TryGetFieldUInt64 returns the value that is contained in the IItemMetadata object and not the value that is stored in the metadata store.
