XRObject.CreateInstance(As * *) (Compact 2013)
3/28/2014
This method converts the specified object that is a type that is different from ItemType into an XRObject<Base> instance that also supports functionality that resembles the Component Object Model (COM).
Syntax
template<typename As>HRESULT CreateInstance(
As ** ppRet)
Parameters
- ppRet
[in] Object pointer of type As to convert into an XRObject<Base> instance.
Return Value
The following table shows the possible return values.
Value |
Description |
|---|---|
S_OK |
The method succeeded. |
E_FAIL |
The method was not successful. |
E_OUTOFMEMORY |
The method implementation could not allocate memory to create a new XRObject<Base> object instance. |
E_POINTER |
The method’s internal call to XRObject.CreateInstance(XRObject<Base> * *) could not create an instance by using the internal object pointer, or the method’s internal call to XRObject.QueryInterface(const IID&,void * *) could not return an interface by using the ppRet pointer. |
Remarks
A generic wrapper class type can use this method to create object instances as an implemented interface. This functionality is analogous to the functionality in a COM class factory object.
