ERROR_INVALID_SCROLLBAR_RANGE - 1448 (0x5A8)
Scroll bar range cannot be greater than MAXLONG.
Updated: Feb 21, 2026
Technical Meaning
The ERROR_INVALID_SCROLLBAR_RANGE error code, with the numeric value of 1448 (0x5A8), indicates that an attempt was made to set a scroll bar range that exceeds the maximum allowable value defined by the system. Specifically, this error occurs when the specified range is greater than the constant MAXLONG, which represents the largest positive value that can be represented in a 32-bit signed integer.
Error Details
This error typically arises in scenarios where applications or APIs attempt to manipulate scroll bar controls on windows or dialog boxes. The system enforces this limit to ensure that all scroll bar operations remain within safe and predictable bounds, preventing potential issues such as overflow errors or undefined behavior.
Usage Context
The ERROR_INVALID_SCROLLBAR_RANGE error is relevant in the context of user interface (UI) development for Windows applications. It can be encountered when developing custom UI elements that include scroll bars, or when using standard Windows controls and APIs to manage scrolling functionality.
Developer Interpretation
Developers should interpret this error as an indication that a parameter passed to a function related to scroll bar operations is out of the acceptable range. This could occur due to incorrect initialization of control parameters or improper handling of user input, leading to values that exceed system-defined limits.
Related Errors
ERROR_INVALID_PARAMETER: A more general error indicating an invalid argument was provided to a function.ERROR_OUTOFMEMORY: An error related to insufficient memory resources, which might indirectly affect scroll bar operations if they require significant memory allocation.
FAQ
Q: What does the ERROR_INVALID_SCROLLBAR_RANGE mean?
A: It indicates that an attempt was made to set a scroll bar range greater than the maximum allowable value (MAXLONG).
Q: How can I avoid this error?
A: Ensure that all parameters passed to functions related to scroll bar operations are within valid ranges. Validate user input and initialize control parameters correctly.
Summary
The ERROR_INVALID_SCROLLBAR_RANGE is a specific technical error code indicating an attempt to set a scroll bar range greater than the maximum allowable value (MAXLONG). Developers should validate their input parameters and ensure that all UI elements are properly initialized to avoid this error.
