Setup

WDomain.Create

Creates a new WObject.

Syntax

int Create<T : WObject>(
out T p_ppObject,
DataFoundation.ObjectId p_poiParentId,
UInt32[] p_aulClassId
);

Parameter

p_ppObject
Type: out T
Variable that receives the interface of the new object.
The variable contains the interface on successful return. The variable is not modified on failure.
Call WObject.Release on the object when you no longer need it.
p_poiParentId
Type: DataFoundation.ObjectId
ID of the parent object.
Remarks: A "parent" object is not really a parent. This information is only used by the system for load optimizations to determine which objects will likely be used at the same time.
p_aulClassId
Type: UInt32[]
Array of classes the object contains.

Return value

S_OK or an error from the Error Codes.

Remarks

This function only creates a temporary object. You need to call WDomain.StoreData and WDomain.Execute or WDomain.ExecuteAsync to create the object in the database.
T can be WObject or a DADL-generated class, derived from WObject
