D1115: Enumeration Value Not Valid

Article
03/27/2021

The parameter [parameter] with value [value] for interface::method is not a valid enumeration value.

Placeholders

parameter: The name of the parameter that received the unexpected type.
value: The invalid enumeration value.
interface: The name of the interface to which the method belongs.
method: The name of the method that received the invalid enumeration value.

Examples

The following example specifies a D2D1_RENDER_TARGET_TYPE enumeration value of 30, which is outside the expected range.

        hr = m_pD2DFactory->CreateHwndRenderTarget(
            D2D1::RenderTargetProperties((D2D1_RENDER_TARGET_TYPE)(30)),
            D2D1::HwndRenderTargetProperties(m_hwnd, size),
            &m_pRenderTarget
            );

This example produces the following debug message:

D2D DEBUG ERROR - The parameter [renderTargetProperties->type] with value [30] 
for ID2D1Factory::CreateHwndRenderTarget is not a valid enumeration value.

Possible Causes

A parameter used an invalid enumeration value.

Fixes

Use a valid enumeration value.

Note

The debug layer currently checks only the individual enumeration values; it does not check whether a bitwise combination is valid.
