  • Άρθρο

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

Placeholders

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
