How to fix Win32 0x0000057E Error? ERROR_TLW_WITH_WSCHILD
The error code 0x0000057E translates to ERROR_TLW_WITH_WSCHILD. This error occurs when you try to create a top-level window (TLW) that also has the child window (WSCHILD) style applied. These styles are mutually exclusive.
Here’s a breakdown of the issue and how to fix it:
Understanding the Error:
- Top-Level Window (TLW): A TLW exists at the top of the window hierarchy and doesn’t have a parent window. It typically has a title bar and borders and can be moved independently on the screen.
- Child Window (WSCHILD): A child window is subordinate to a parent window. It doesn’t have a title bar or borders by default and inherits some properties from its parent.
Why the Error Occurs:
A window cannot be both a top-level window and a child window simultaneously. Setting both the TLW and WSCHILD styles during window creation leads to this error.
Fixing the Error:
There are two main approaches to fix this error, depending on your intended window behavior:
-
Create a Top-Level Window:
- If you want a window that behaves independently with a title bar and borders, remove the WSCHILD style from your window creation code. This will ensure it’s created as a top-level window.
-
Create a Child Window:
- If you want the window to be subordinate to another window and inherit properties from its parent, remove the TLW style and ensure it has a parent window specified during creation. A child window typically doesn’t have a title bar or borders by default.
