PRB: Calling LoadMenuIndirect() with Invalid Data Hangs System

Last reviewed: September 29, 1995
Article ID: Q131281

The information in this article applies to:

Microsoft Win32 Application Programming Interface (API) included with:
```
    - Microsoft Windows 95 version 4.0
```

SYMPTOMS

Under Windows 95 if you call LoadMenuIndirect() with invalid data, the system hangs (stops responding).

CAUSE

Invalid data anywhere in the array of MENUITEMTEMPLATE structures passed to the LoadMenuIndirect() function may cause this problem. An example of this might be an extra NULL byte after a MENUITEMTEMPLATE structure.

Under Windows NT version 3.5, passing the same invalid data in the MENUITEMTEMPLATE structure causes LoadMenuIndirect() to return NULL, with GetLastError() reporting an ERROR_INVALID_DATA value.

STATUS

This behavior is by design.
