cxE_NOINTERFACE Constant

In This Article

Specifies the default error code indicating that a class does not support the requested interface.

#Declaration

Delphi
const cxE_NOINTERFACE = HResult($80004002);

#Remarks

The QueryInterface function implementations in many DevExpress classes return this global constant instead of 0 if a class does not implement the requested interface. A QueryInterface function implementation accepts the interface’s globally unique 128-bit identifier (GUID) as the IID parameter.

Note

The cxE_NOINTERFACE global constant value matches the Windows API E_NOINTERFACE error code.
