  • Article

The parameter [parameter] for interface::method is not optional. A NULL pointer was passed. This will cause Direct2D to crash.

Placeholders

The name of the parameter that contains the NULL pointer.

interface

method

Examples

The following example shows that the FillGeometry method receives a NULL pointer for the non-optional geometry parameter.

        m_pRenderTarget->FillGeometry(NULL, m_pYellowGreenBrush);

This example produces the following debug message:

D2D DEBUG ERROR - The parameter [geometry] for ID2D1RenderTarget::FillGeometry is not optional. 
A NULL pointer was passed. This will cause Direct2D to crash.

Possible Causes

Fixes
