PC OS2: Running CONVERT.EXE Under OS/2 1.3Last reviewed: October 19, 1995Article ID: Q89585 |
The information in this article applies to:
SYMPTOMSCONVERT.EXE, which is included with version 3.0 of Microsoft Mail for Presentation Manager, converts version 2.1 folders to the version 3.0 Mail message file (MMF) format. If you run CONVERT.EXE from an OS/2 prompt or by selecting it from a file list in the File Manager while Mail is running, the program causes a protection violation and terminates.
CAUSEThis problem is caused by a design limitation of the Windows Libraries for OS/2 (WLO) dynamic-link libraries (DLLs). The shared DLL technology identifies tasks using the stack segment register. Under Microsoft Windows, this stack value is unique across all applications. With WLO applications, this is not guaranteed because the stack value is relative to each application. CONVERT.EXE has the same stack segment value as the Mail Spooler (MAILSPL.EXE), and this causes the protection violation.
RESOLUTIONShut down Mail before you run the conversion utility.
