Windows cannot end this program

[Lynn Wakefield]

With the new PBCC5 if I click on X to end the program (console) it works fine on my windows XP home edition computer. But with my windows XP pro computer it shows a box:

"Windows cannot end this program. It may need more time to complete an operation.

To return to Windows and check the status of the program, click Cancel."

It shows 2 boxes - EndNow - Cancel

Any help or fix? TIA Lynn

You need to post code and/or send to [email protected] to get explicit help.

It sounds like you may have an endless loop in the program

Windows cannot end this program

All my old programs compiled under PBCC4.04 work ok. If re-run under PBCC5.0 I get the same results (can't end console with the Upper 'X').
Same results if run in the IDE or from windows.
A small example:

#COMPILE EXE
#DIM ALL
   GLOBAL test,n1(),a AS STRING
   GLOBAL x,z,zz,Flagg,row,col,block,BlockNum() AS LONG
FUNCTION PBMAIN () AS LONG
   DIM n1(1 TO 81) AS STRING
   DIM BlockNum(1 TO 81) AS LONG
   Flagg = 0     ' Print to printer      0 = Screen
   IF Flagg THEN
        XPRINT ATTACH DEFAULT
        XPRINT WIDTH 2
        XPRINT FONT "New Courier",7,0
   END IF
    FOR z = 1 TO 81
        BlockNum(z) = CEIL(z/3 MOD z) MOD 3.1
        IF z > 27 THEN BlockNum(z) = BlockNum(z) + 3
        IF z > 54 THEN BlockNum(z) = BlockNum(z) + 4
    NEXT z
   CLS
   IF Flagg THEN XPRINT "  z            row         col         block" ELSE _
        PRINT "  z            row         col         block"
   IF Flagg THEN XPRINT "------------------------------------------------" ELSE _
        PRINT "------------------------------------------------"
    FOR z = 1 TO 81
            IF z = 28 OR z = 55 THEN IF Flagg THEN XPRINT " " ELSE PRINT " "
            row = CEIL(z / 9)
            col = CEIL(z MOD 9.1)
            IF z = 55 AND Flagg = 0 THEN
                WAITKEY$
                CLS
                PRINT "  z            row         col         block"
                PRINT "------------------------------------------------"
            END IF
            block = CEIL(z/3 MOD z) MOD 3.1
            IF row >3 THEN block = block + 3
            IF row >6 THEN block = block + 4
            IF Flagg AND z < 10 THEN XPRINT "  ";
            IF Flagg THEN XPRINT _
                STR$(z)+"              "+ STR$(row)+"          "+STR$(col)+"             "+STR$(BlockNum(z)) ELSE _
                PRINT z,row,col,BlockNum(z)
    NEXT z
    zz = CEIL(46 MOD 9.1)
    IF Flagg THEN XPRINT zz ELSE PRINT zz
    IF Flagg THEN PRINT "Hit any key to continue . . ."
   WAITKEY$
   IF Flagg THEN XPRINT CLOSE
END FUNCTION

TIA Lynn

The differences between v4 & v5 are for PowerBasic to explain, but if you add a message loop to your application and deal with WM_CLOSE properly, the problem will go away.

Lynn,
try adding this line to the start of your code:

#BREAK ON

Paul.

[Chris Holbrook]

or even add a consolectrlhadndler as below from thread http://www.powerbasic.com/support/pb...ighlight=close:


... I should have said that it is untested with V5 of PBCC, which I am too tight to buy.

Ending console program

Chris,

I tested your code with PBCC5 and it does work but I had to add END after the SLEEP 1000 instruction in order to shut down the program.
You can hear the Beep sound coming from the Windows Error but it is the only drawback.
Lynn, why not starting to work with a Graphical Console like the demo I posted here a few days ago ?
It is a bit more work but the result is well worth it.

[Guy Dombrowski]

Beep

Just noticed that the beep came from your code Chris.
Removed it and everything works like a charm.

[Chris Holbrook]

... everything works like a charm.

how rare is that!

Windows cannot end this program

You guys (& gals) are great! Thanks to all for the help!
Paul, your #BREAK ON fixed it, The program even closes faster!

Guy, I am going to start working with the Graphical Console & may need a little help along the way.

Thanks again, problem solved! Lynn (male)!
