ERROR_INVALID_EDIT_HEIGHT - 1424 (0x590)
Height must be less than 256.
Updated: Feb 21, 2026
Overview
The error code ERROR_INVALID_EDIT_HEIGHT (1424, 0x590) indicates that an operation involving edit height has been attempted with a value that exceeds the allowable limit.
Technical Background
This error is encountered when a function or API related to editing text or graphical elements in Windows encounters a parameter that specifies an edit height greater than 256 units. The ERROR_INVALID_EDIT_HEIGHT is a specific error code used by various Windows APIs, particularly those dealing with text and graphics.
Error Details
The error message 'Height must be less than 256' suggests that the value provided for the edit height parameter in an API call or function is out of the acceptable range. The maximum allowable value for the edit height is 255 units, as specified by the Windows API.
Common Causes
- Invalid Parameter Values: The edit height parameter passed to a relevant API function exceeds the maximum allowed value (256).
- Incorrect Object Type: The operation being performed is not compatible with the object type or context in which it was invoked, leading to an invalid height specification.
Real-World Context
This error can occur when working with text editors, graphical user interfaces, or any application that manipulates text or graphical elements. For instance, if a developer attempts to set the edit height of a text box or a graphical element in a Windows application beyond 256 units, this error will be triggered.
Is This Error Critical?
The severity of this error is not critical; however, it can prevent certain operations from completing successfully. Applications should handle this error by either correcting the parameter value or adjusting the operation context to ensure compliance with the specified limits.
How to Diagnose
To diagnose ERROR_INVALID_EDIT_HEIGHT, developers should:
- Review Operation Context: Ensure that the operation being performed is appropriate for the object type and context in which it is invoked.
- Validate Parameters: Verify that all parameters, including edit height, are within their valid ranges. The maximum allowable value for edit height is 255 units.
- Confirm Object Types: Confirm that the object types involved in the operation support the specified parameter values. For example, text boxes and graphical elements may have different constraints on edit height.
How to Resolve
To resolve ERROR_INVALID_EDIT_HEIGHT, developers should:
- Correct Parameter Usage: Ensure that all parameters, including edit height, are set within their valid ranges (less than 256 units).
- Adjust Operation Context: If the operation context is not appropriate for the object type or parameter values, adjust the operation to ensure compliance with system limits.
Developer Notes
Developers should be aware of the specific constraints imposed by Windows APIs and ensure that all parameters are validated before being passed to relevant functions. This can prevent errors such as ERROR_INVALID_EDIT_HEIGHT from occurring.
Related Errors
- ERROR_INVALID_PARAMETER: A general error indicating an invalid parameter was provided to a function or API.
- ERROR_OUTOFMEMORY: An error indicating that the system could not allocate sufficient memory for the operation.
FAQ
Q: What does ERROR_INVALID_EDIT_HEIGHT mean?
A: It indicates that an edit height value greater than 256 was provided to a relevant Windows API function, which is out of the allowable range.
Q: How can I prevent this error from occurring?
A: Ensure that all parameters, including edit height, are set within their valid ranges before passing them to relevant functions. Validate input data and operation context to avoid exceeding system limits.
Q: Can this error be critical for my application?
A: The severity of the error is not critical; however, it can prevent certain operations from completing successfully. Applications should handle this error by correcting parameter values or adjusting operation contexts as necessary.
Summary
ERROR_INVALID_EDIT_HEIGHT (1424) is a specific Windows API error indicating that an edit height value greater than 256 was provided to a relevant function, which exceeds the allowable limit. Developers should ensure that all parameters are validated and within their valid ranges to avoid this error.
