Full screen mode under Windows 7-32

[Gunther]

Is there a way to switch into the full screen mode (command prompt) under Windows 7-32?

Tricky question. I don't think so. Maybe you should ask a physicist.
You could, of course, have a sophisticated program that enables Full Screen Mode, that you invoke from the command prompt,...
...But, then you'll be stuck, and have no way back to 'Windowed' mode. It's kind of like time-travel, in that respect,...

If there is a way to do this, it's probably with: Windows Management Instrumentation Command-Line,...although, I don't know of a WMI class (and, it would probably be: Win32_DesktopMonitor Class) that has a method named: FULLSCREEN,...

I can't imagine why you'd want to do this,...do you have your high level clearances ??? Did you check your thunks ???

Hi Zen,

...Just for fun,...here is a blog entry from Raymond Chen: How Do I Switch a Window Between Normal and Fullscreen ?, Apr 2010

you're a little quipster.  :lol: But thank you for the link with Raymond Chen's blog post.  :t Interesting.

the shellexecute allow command prompt and all windows commands

NVidia and ATI, along with Microsoft, decided not to support full screen consoles (really, all text-modes) in their drivers from Vista onwards.

Do the alternative, change the window size and placement with the standard settings for the console. Change the font sizes if you need to and you should get what you are after.

That's a way to go, indeed.

Is that true? With the old XP the full screen did work well.

That g_wpPrev:WINDOWPLACEMENT should be global ?

[dedndave]

when you use a full-screen console under XP, the OS uses the fonts that are inside the VGA BIOS ROM
which is faster, i guess   :redface: (no stretching of chars)
also, you can use graphics modes like 13h, etc and program the VGA registers under 16-bit code, of course
but, if the VGA manufacturers quit supporting the BIOS fonts - that all goes away
and, under 64-bit windows, you can't use the other graphics modes in 16-bit code - lol

you can make a full-screen GUI window and emulate a console, though
which probably isn't as hard as it might sound

here's a routine i use for display (no keyboard input, for now)
you'll have to work out the font, colors, and buffer stuff, of course

;*************************************************************************************************************

        OPTION  PROLOGUE:None
        OPTION  EPILOGUE:None

dTxtOut PROC    lpTxt:LPSTR

;intended to more-or-less emulate the console StdOut function
;some elements of behaviour mock that of the console - others mock that of a text editor like notepad
;
; 1) The FormFeed character (12) may be used to clear the screen.
; 2) The Bell character (7) is not expanded to a sound; It is a visible character.
; 3) Tabs are expanded to spaces that overwrite existing text, similar to the console.
;    Text editors simply move the cursor or, perhaps, insert spaces.
; 4) Spaces (32) at the end of a line count as visible; Nulls (0) do not.
;    This primarily affects scrollbar behaviour, which is similar to a text editor.
; 5) Because Nulls are used as string terminators, there is no convenient way to clear an area.
;    For this reason, a ClearLine function is provided that will clear to end-of-line from a given position.
;    The ClearLine function does not alter the location counters.
; 6) The dTxtOut function line-wraps and updates location counters, similar to a console.
;    However, I never liked the way the console (or VT-100) handled line-wrap and CR/LF.
;    Therefore, the X location counter has special properties:
;   a) We allow the X location to be equal to the row length (normally, the max is row length - 1).
;      This indicates that the last char on the line has been written, and no more.
;   b) If the current X location is equal to the row length:
;      1) If the buffer location is calculated to stream the next visible char, a NextLine is generated.
;      2) CarriageReturn and LineFeed behave as desired, without inserting extra blank lines.
;      3) A NextLine is generated prior to expanding a Tab.
;   c) Care must be taken if retrieving the current location.
;      The caller must be aware of the maximum valid X position.
; 7) When a line feed is streamed in a console window, the viewable portion is scrolled so
;    that the last line is visible. This behaviour can be irritating if you are trying to view
;    older screen text. In this implementation, a single line is scrolled, instead. This permits
;    the viewing of older text while still letting the viewer know that an update has occured.
; 8) Unlike the console, all text uses the same 2 colours; foreground and background.
;    This version does not implement character attributes.

Dave,

here's a routine i use for display (no keyboard input, for now)
you'll have to work out the font, colors, and buffer stuff, of course

but the idea is good. On the other hand, for 16-bit code under 64-bit Windows you can set up a virtual machine with DOS and all old standard VGA modes are useable, including ModeX.

Hi ToutEnMasm,

unfortunately, the entire site is in French. The EXE works under Windows 7-64, but nothing happens.

A brief translate:
1° soluce)Open a  dos window and press Alt+enter,you go full screen with the prompt message.
2° soluce) Modify a register key (use regedit):
       HKEY_CURRENT_USER\Console\FullScreen = 1
