The information in this article applies to:

  • Microsoft CodeView for MS-DOS, version 4.1

SYMPTOMS

When using CodeView to run a DOS-extended application that was built using the Phar Lap 286|DOS-Extender Lite that ships with Visual C++, the program may appear to run properly, but when control returns to CodeView, it may hang. You may also receive a message stating system integrity has been violated.

RESOLUTION

You can develop DOS-extended applications using Visual C++ together with the Phar Lap's 286|DOS-Extender Lite, but these applications cannot be directly debugged with CodeView. Instead, Phar Lap supplies a full-featured 286|DOS-Extender SDK and it includes a utility that allows CodeView for Windows to debug DOS-extended applications. There is a README file included with the 286|DOS-Extender Lite that contains more information about the package. For support and questions concerning both the 286|DOS Extender Lite and the 286|DOS-Extender SDK contact Phar Lap Technical Support at (617) 661-1510.
