Full Screen Output Problem

[Fred Lampart]

Need a little help...

I'm not able to get a Window (vs Full Screen) output screen to a
a DOS program I've written.

The Properties Screen Usage tab has the Windows Usage option
checked (not the Full Screen option) in the executable I created
but whenever the program is run the screen output defaults to a
full screen.

Could something in my compiled program code be over-riding the
selected "Windows"option?

I'm compiling within PB 3.0b and am using Win XP.

P.S. Although its probably not related, when I try running the
program in Vista, I get an error message that Vista can not run
in Full screen mode.

Too many problems, too little time

Is your program switching to a graphics mode? Can only run text mode in a Window.

Laurence,
Really sorry I haven't replied earlier. Thought that I had
requested email notification when someone responded but I had
not.

What code in my program would cause a switch to graphics mode?

I've turned off the Bitmap option and switched to (i.e. applied)
the Truefonts option in the executable file but the screen still
reverts to full screen when the program runs.

BTW; I don't draw anything (circles, etc.) but I do use a Paint statement
to fill in an enclosed area.

Arthur,
I apologize for not responding earlier but I was under the mistaken
impression that I had requested email notification of a response but
I hadn't.

The "Normal Window" choice was already selected in the Run
field of my executable file.

Any other suggestions/tips?

>I do use a Paint statement

If PAINT works, you are using a graphics screen. And if you
are using graphics in PBDOS, you will always get full screen display
(unless there's a third-party solution to change that).

There is an internal PB variable (see Help, or manual) that you can
check, to see what screen you are in, if for any reason you don't know.

SCREEN is the statement that determines text/graphics ; its default is
text. So check your code for a SCREEN statement. There must be one,
and it must be non-zero, at least by my reckoning. You should be able to
get a Windows box rather than full screen if you use SCREEN 0 -- and an
error message for any graphics command.

I just remmed out my program's Paint statements and have searched and
for and replaced Screen Statements >0 with Screen 0 but the
program still reverts to a full screen mode at execution.

Will check again to be sure all the above program elements I'm
pulling together with INCLUDE statements have all been changed.

I've found the Internal PB Variable (pbvScrnMode)you referred to
but am a little a fuzzy on on how to find its value. Manual time...

If I've already made all the above referenced changes correctly,
I've got to assume there are other graphics statements within
my program forcing it into the graphics mode.

Is there a list anywhere of All graphics ststements? Checking
the manual statement by statement is going to be big job.

Emil,

I found a Screen statement that I had not set to zero per your
recommendation. After doing so my problem (program reverting to full
screen mode) went away.

Thanks a lot for the help...

P.S. I'm still going to look into using the internal PB variable to
learn more about them.

mike,

see my reply to emil. the problem i had was caused by using a screen
statement > 0.

To find the value of pbvScrn you could simply use
PRINT pbvScrn or X=pbvScrn. Alternatively, see below.

p. 179 of the PB User's guide (manual) lists the graphics commands as:
setup commands SCREEN, WINDOW,WIDTH,VIEW,COLOR & PALETTE
drawing commands CIRCLE,DRAW,GET,LINE,PAINT,PMAP,POINT,PRESET,PSET,PUT

I will not swear that the list is exhaustive. Also, some of the commands
such as SCREEN, COLOR, VIEW & WIDTH might have a non-graphics use.
So, especially if your program includes numerous INCLUDE files it might
be easier to have the program periodically poll the value of pbvScrn,
rather than you yourself doing a word-search on all commands, in every
file. For example, periodically call this function:


FUNCTION CheckScreenMode
STATIC X%, Count%
IF Count%=0 then X%=666 'on first call, force a print-out
IF pbvScrn <> X% THEN
X%=pbvScrn
INCR Count
PRINT "You are now in SCREEN mode ";X%
IF Count% > 1 THEN PRINT "Number of mode changes = ";Count%
END IF
FUNCTION=X%
END SUB

As info, the WIDTH statement was needed on some laptops.
If this is a commercial program it might be advisable to put
in an option to execute the statement (if needed.)
