This article was previously published under Q83029 SUMMARY
This article discusses the video modes supported while running MS-DOS-based
applications in a window under Microsoft Windows operating system version
3.1 in 386 enhanced mode.
MORE INFORMATION
In Windows 3.1, all video drivers perform identically to the drivers
shipped with Windows 3.0 when you run MS-DOS-based applications in a
window, except the following drivers:
The 8514, TIGA, SVGA, and VGA drivers support the following
video modes when you run MS-DOS-based applications in a window:
The other drivers that ship with Windows 3.1 and drivers based on
Windows 3.0 are only capable of running mode 0Fh in a window.
These other drivers are able to display MS-DOS-based applications that
use video modes 0Dh, 0Eh, 10h, 11h, 12h in a window if the current
screen does not need to be redrawn or updated. This way it is possible
to select and copy text to the Clipboard. When it is time for the
screens to be updated, the application must be switched back to full
screen. Switching from a window to full-screen mode and back can be
done in two different ways:
- Make the MS-DOS-based application active and then press ALT+ENTER.
-or-
- From the Control menu (-) in the upper-left corner of an
MS-DOS-based application running in a window, choose Settings,
select Full Screen, and then choose the OK button.
If you attempt to update an MS-DOS-based application running in a
window in a mode other than 0Fh, the following error message appears:
You cannot run this application while another high-resolution
application is running.
After this has come up and been dismissed, Windows beeps if you make
any subsequent attempt to update the screen, press keys, and so on.
The application must be changed to full-screen mode before continuing.
Video mode 13h is not capable of running in a window. If you attempt
to run a 13h-mode screen in a window, the following error message
appears
Insufficient Memory
and the screen will have to be changed back to full screen before the
MS-DOS application is viewable.
