Visual C++ README.WRI Part 1-Configuring Your System

The information in this article applies to:

• Microsoft Visual C++ for MS-DOS, version 1.0

SUMMARY

The text below presents information in Part 1 of the README.WRI file distributed with Microsoft Visual C++ version 1.0. Setup installs README.WRI in the MSVC\HELP directory.

MORE INFORMATION

FILES= Setting in CONFIG.SYS

The number of files specified in the CONFIG.SYS file should be at least 50. Check that your CONFIG.SYS file contains the following line:

   FILES=50

Other Configuration Information

Many important notes on configuration issues and hardware problems are described in the CONFIG.WRI file. This file can be viewed using the ReadMe Tech Note viewer found in the Visual C++ program group.

Using an ATI Mach 32 Windows 3.1 Video Driver

If you encounter problems with the Mach 32 driver, ATI suggests that you modify the [mach32] section of WIN.INI to set "DeviceBitmap =off" and "DeviceBitmapDraw=off". If these changes do not eliminate the problems, use the Windows Control Panel to switch to the 8514 video driver. The 8514 driver can be used with the Mach 32 display adapter.

A newer version of the display driver may solve these problems. The phone number for ATI User Support is (905) 882-2626. The most recent drivers are available on the ATI BBS. Use your modem to dial (905) 764-9404 to download these drivers.

Using MASM 6.10 with Visual C++

If you want to use MASM 6.10 with Visual C++ you should install the MASM 6.1a patch. If you already have MASM 6.1a you do not need to install the patch. You can check to see which version of MASM you have by running ML at the MS-DOS prompt. To get the patch file, contact Microsoft Product Support Services at (425) 646-5109 to receive the patch file.

The TOOLS.WRI file, available through the TechNote viewer in the Visual C++ program group, describes a workaround that does not require the patch.

Installing Microsoft Foundation Class Libraries

If you install Visual C++ from floppy disks, Microsoft Foundation Class libraries are prebuilt only in medium and large model. If you want any other models you need to build the libraries yourself. See "Appendix B" of the "Class Libraries User's Guide" to learn how to build Microsoft Foundation Class libraries from the provided library source code.

Class libraries for all memory models are available prebuilt on the CD-ROM edition of Visual C++.

Starting Windows After Installing Visual C++ from CD-ROM

If you installed Visual C++ from CD-ROM and chose to leave some files on the CD-ROM instead of installing them on your hard drive, the Visual C++ CD-ROM disk may need to be in the CD-ROM drive when you start Windows.

Unexplained Resource Compiler Errors

You may get unexplained errors while using the Resource Compiler if you don't have at least 450K of available conventional memory. See your MS-DOS User's Guide and Reference for information on configuring your system to increase the amount of conventional memory.
