ERROR_INVALID_SPI_VALUE - 1439 (0x59F)

Technical Meaning

The ERROR_INVALID_SPI_VALUE error code, with the numeric value of 1439 and the hexadecimal representation of 0x59F, signifies that a system-wide parameter (SPI_*) has been provided an invalid or unsupported value. This error typically occurs during API calls where specific parameters are expected to conform to certain constraints.

Error Details

The ERROR_INVALID_SPI_VALUE is a generic error code used by the Windows operating system to indicate that a parameter passed to a function or API call does not meet the required criteria for valid values. The term 'SPI_' stands for System Parameter Identifier, which refers to parameters that are recognized and managed at the system level.

Usage Context

This error is commonly encountered in scenarios where specific system-wide parameters are expected as input. These parameters can include but are not limited to display settings, power management configurations, or other system-related attributes that require predefined values for proper operation.

Developer Interpretation

When encountering the ERROR_INVALID_SPI_VALUE, developers should focus on validating and ensuring that all parameters passed to relevant API calls adhere strictly to the expected value ranges and types. This includes verifying that any SPI_* parameters are correctly specified according to the documentation provided by Microsoft or other relevant sources.

Related Errors

• ERROR_INVALID_PARAMETER (0x57)
  • Indicates an invalid parameter in a function call, but does not specifically identify system-wide parameters as ERROR_INVALID_SPI_VALUE does.
• ERROR_BAD_COMMAND (0x124)
  • Suggests that the command or operation being attempted is not recognized by the system, which could be related to incorrect SPI_* values in certain contexts.

FAQ

Q: What causes ERROR_INVALID_SPI_VALUE?

A: This error typically occurs when an API call receives a parameter value that does not match the expected range or type for a system-wide (SPI_*) parameter. Developers should ensure all parameters are correctly specified according to the documentation.

Q: How can I resolve this issue?

A: Review and correct any invalid SPI_* parameters in your code, ensuring they conform to the valid value ranges as documented by Microsoft.

Summary

The ERROR_INVALID_SPI_VALUE error is a specific indication that an API call has received an invalid system-wide parameter. Developers should carefully validate all parameters passed to relevant functions to avoid this issue and ensure proper operation of their applications on Windows systems.
