IXpsOMObjectFactory::CreatePackage method (xpsobjectmodel.h)

Creates an IXpsOMPackage interface that serves as the root node of an XPS object model document tree.

Syntax

HRESULT CreatePackage(
  [out, retval] IXpsOMPackage **package
);

Parameters

[out, retval] package

A pointer to the new IXpsOMPackage interface.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the table that follows. For information about XPS document API return values that are not listed in this table, see XPS Document Errors.

Remarks

The code example that follows illustrates how this method is used to create a new interface.

IXpsOMPackage    *newInterface;

// Note the implicit requirement that CoInitializeEx 
//  has previously been called from this thread.

hr = CoCreateInstance(
      __uuidof(XpsOMObjectFactory),
      NULL, 
      CLSCTX_INPROC_SERVER,
      __uuidof(IXpsOMObjectFactory),
      reinterpret_cast<LPVOID*>(&xpsFactory)
      );

if (SUCCEEDED(hr))
{
    hr = xpsFactory->CreatePackage (&newInterface);
    if (SUCCEEDED(hr))
    {
        // use newInterface

        newInterface->Release();
    }

    xpsFactory->Release();
}
else
{
    // evaluate HRESULT error returned in hr
}
