Nice Work!

Hi Richard;

Thanks for the Graphic Progress Bars Sample. I can see a number of uses for it.

**Scott Turchin** · 29 Sep 2008, 02:51 PM

I have PBWIn 8.04, is that included or a 3rd party add-on?

**Richard Angell** · 29 Sep 2008, 03:42 PM

Included ... the Power BASIC Graphics Toolset was launched with versions PBCC 4/ PBWin 8. In the help file Programming Reference\Dynamic Dialog Tools section is a secion on Graphics. In the samples for DDT you will also find several examples in its Graphics subdirectory branch. Most of the graphics statements and functions beginning with the keyword GRAPHIC.

Also in those version the XPRINT command set waas introduced.

Both of these tool groups were improved and expanded in 5.0/9.0.

Since you have 8.04, you will need to eliminate the FONT NEW and FONT END statements and change the GRAPHIC SET FONT to the older GRAPHIC FONT statement (see the help file).

Note that the example shown only is for PBWin, since it uses graphic controls. However, the basic idea of aa progress bar can also be effected in a GRAPHIC WINDOW where one simply replaces an area of the persistent bitmap with (1) a blank progress bar control bitmap; and then (2) a specific bitmap of the current bar, digit or blip at the position or size desired. GRAPHIC COPY would be used for 1, where other graphic commands would be used as in the example code I posted to draw or write the desired image or text or even both.

IN PBWin 9, ProgressBar control statement and functions have been added to Power BASIC. However for uses beyond the nore, the Graphic Toolset can get the job done. too.

**Paul Dixon** · 29 Sep 2008, 04:16 PM

Similar to a progress indicator but faster so it's more useful as an indicator that your code is busy. It's also more like a Cylon!

Code:

'Busy Indicator
$INCLUDE "WIN32API.INC"

%stop=0
%draw=1
FUNCTION DrawBusyIndicator ( BYVAL xPos AS LONG, BYVAL yPos AS LONG, _
                        BYVAL DoWhat AS LONG, BYVAL wide AS LONG, BYVAL dw2 AS LONG) AS LONG
STATIC cnt&,col&() ,hWin???,TimerHandle&,wscale!,high&

SELECT CASE DoWhat
    CASE %stop
        timeKillEvent TimerHandle&
        GRAPHIC WINDOW END

    CASE %draw
        IF cnt&=0 THEN
            GRAPHIC ATTACH hWin???, 0  ,REDRAW
            GRAPHIC CLEAR col&(0)
        ELSE
            FOR bar&=0 TO 15
                position&=(cnt&+bar&) AND &h7f
                IF (position& AND &h40) THEN position&=(position& XOR &h3f) AND &h3f
                GRAPHIC BOX ((position&*4)*wscale!,0)-(((position&+1)*4)*wscale!,high&),0,col&(bar&),-1
            NEXT
        GRAPHIC REDRAW
        END IF

        INCR cnt&

    CASE ELSE
        'it's not stop or draw so it must be start. doWhat is now the colour to use
        'colour should be saturated so R,G and B are either 00 or FF (e.g.&hFFFFFF or &hFF00FF..)
        'create a window to draw the busy indicator in
        GRAPHIC WINDOW "", xPos, yPos, wide&, dw2  TO hWin???
        wscale!=wide/256
        high&=dw2
        'set the colours
        BaseColour&=doWhat
        DIM col&(15)
        temp&=BaseColour&

        FOR r&=15 TO 0 STEP -1
            temp&=r&*8+127      'to make more Cylon like change to temp&=r&*16
            col&(r&)=(temp&*65536 +temp&*256+temp&) AND BaseColour&
        NEXT
        'start the timer
        '10=milliseconds between triggers, 0=maximum timer resolution
        TimerHandle& = timeSetEvent ( BYVAL 10, BYVAL 0, CODEPTR(DrawBusyIndicator), BYVAL %draw, BYVAL %TIME_PERIODIC)

    END SELECT

END FUNCTION


FUNCTION PBMAIN () AS LONG

PRINT "Press a key to exit"
'start the busy indicator
DrawBusyIndicator(200,400,%RED,100,10) 'at position 200,400 and 100 wide x 10 high

DO
    SLEEP 10 'this is where you do the main job while the Busy Indicator is displayed
LOOP UNTIL INSTAT

'end the busy indicator
DrawBusyIndicator (0,0,%stop,0,0)

END FUNCTION

**Richard Angell** · 29 Sep 2008, 04:33 PM

Nice, Paul.

Code should transfer easily to PBWin as well.

**Scott Turchin** · 29 Sep 2008, 04:42 PM

Why can't I just use the progress bar instead?

If this is free, requires no additional DLL's, nothing else - (This is a single EXE app that can be run from a CD/floppy/usb) then I can try it.

BUt, got a compile error right off thebat - period not allowed - CB.HNDL

**Richard Angell** · 29 Sep 2008, 05:39 PM

Scott,

Simply remove the period. It's a PBWin 9 introduction. However there is still the font issue to use the older commands, so hre's a compatible PBWin 8 version:

I can see where this is going (especially after my 80's flashback in NH on vacay)

Could be a Cylon, or even KITT, (I even saw someone that not only had a replica of the A-Team van (too bad the driver had the doors locked or I wouldve gotten out), and after the girl I saw this weekend....hmmmm I may not come back to the new era for a while, I am having tooooo much fun *LOL*)

On the serious side though, I do not see why a progressbar can not be used....its the same general concept, and you can increase/decrease speed of the increment/decremets

**Dave Biggs** · 30 Sep 2008, 12:05 AM

A progress bar could be used..

PBS_MARQUEE Version 6.0 or later. The progress indicator does not grow in size but instead moves repeatedly along the length of the bar, indicating activity without specifying what proportion of the progress is complete. Note Comctl32.dll version 6 is not redistributable but it is included in Microsoft Windows XP or later. To use Comctl32.dll version 6, specify it in a manifest.

(You'd also need %PBS_MARQUEE = &H08 as it is missing from CommCtrl.inc)

But PB's Graphic commands have to be the way to go..

Yup - that's exactly what it is, it was a part of my BBSDown! and InterSceptre programs from the Dos days...

**Scott Turchin** · 30 Sep 2008, 10:22 AM

WHOA!!!!!!!!!!!!

HOLD THE FORT!!!

That is HOT HOT HOT!!!

Now I understand what it's doing - that is HOT HOT HOT...

I have it sorta running, at least one direction, reversed it and am syncing it with a timer to run every 5 seconds or so....

THis has IMMENSE potential!!!!!!!!!

Very cool!!!!!!!!!!

**Scott Turchin** · 30 Sep 2008, 11:45 AM

OK You guys win, THis is phenomenal, I thought the graphics package was a 3rd party etc etc...

Make a g_Finished global variable and set it TRUE when the program exits, drop this thread in and check it out.....
