Q30364

5.10 6.00 6.00a 6.00ax 7.00 | 1.00 MS-DOS | WINDOWS kbprg -- The information in this article applies to: - The C Run-time (CRT), included with: - Microsoft C for MS-DOS, versions 5.1, 6.0, 6.0a and 6.0ax - Microsoft C/C++ for MS-DOS, version 7.0 - Microsoft Visual C++ for Windows, version 1.0 -- In Microsoft C versions 5.0, 5.1, 6.0, 6.0a, 6.0ax, C/C++ version 7.0, and Visual C/C++ version 1.0, when trying to remap the default black background color using _remappalette and _remapallpalette, neither will work if a Hercules monochrome graphics card is installed. These functions do not support the Hercules card. On page 488 of the &quot;Microsoft C Optimizing Compiler: Run-time Library Reference&quot; for version 5.1, there is a note stating that _remappalette and _remapallpalette work only with an EGA or VGA card. In the online help for C 6.0, 6.0a, 6.0ax, C/C++ version 7.0, and Visual C/C++ version 1.0, there is a note explaining that either of these functions will generate an error if they are called on a system with an Olivetti and Hercules display adapter.
