Burgoyne) Newsgroups: comp.windows.ms Subject: No free MS support for SDK; How to use lots of mem in a Win program? Message-ID: <1990Aug19.132046.24146@eng.umd.edu> Date: 19 Aug 90 13:20:46 GMT Sender: news@eng.umd.edu (The News System) Organization: College of Engineering, Maryversity of Uniland, College Park Lines: 54 PART 1 ^^^^^^ Microsoft no longer provides free technical support for questions relating to the SDK other than its installation. It used to provide such support for previous versions, < 3.0, of the SDK. (I know, I have gotten answers from them in the past.) Technical support over toll-free 800 numbers is not what we're talking about. Persons are referred to subscribing to Microsoft online, at $495 a year for "12 hours of connect time". Quarterly reports from Microsoft indicate that it is profitable. (!!!!) Again, Windows program development becomes more complex and available only to the deeply pocketed. I realize that an infinite number of different questions about the SDK could be asked, but no free support at all? Does anyone have any suggestions about what the user group can do? Does anyone have any experience with trying to get answers through Compu$erve? PART 2 ^^^^^^ The question I am trying to get answered is the following. How do we go about using large amounts of memory in our programs we develop with SDK version 3.0? I am using MS C compiler 6.0, SDK version 3.0, Windows version 3.0. The MS Windows SDK book "Tools" says on page 1-3 that the compact and large models are not recommended for Windows programs because data segments of programs created with compact or large models are fixed, and because only one instance of such programs can be run. If anyone can answer any of the following questions, I would be very happy if you do so. Can one use the medium model and have data larger than 64K if it is global? Can one use the medium model and have global arrays larger than 64K? Is it ever possible to have arrays larger than 64K? What is the general strategy for using lots of memory in a Windows program? Has anyone written a program which uses more than 640K? What are you doing and how did you do it? *-----------------------------------------------------------------------------* | Robert Burgoyne CALCE Center for Electronics Packaging | | Industrial Liaison University of Maryland | | burgoyne@eng.umd.edu College Park, MD 20742 | | (301)-454-0348 USA | | Compu$erve: 76234,2425 | | | | "Improving the quality of electronics hardware through software | | development and research into physics of failure models." | *-----------------------------------------------------------------------------*
