1. W98 crash running Calculat.exw from Judith's IDE
Does anyone else have a problem running the example program
Calculat.exw *outside* Judith's IDE?
Error occurs if run then immediately close the app.
W98 reports approx 5 errors, 1st one is:
EXW caused an exception c0000027H in module KERNEL32.DLL at
015f:bff88083.

That would be Exe.exe size 77824 dated 9/12/2001.
(not sure if that date is when built or I d/l'd it)
Bizzarely, If i calculate eg 9*5= then it crashes less than if I just
open & close the app - either way it crashes, however.
- Everything else (so far) seems to run fine on my system.

It works fine for me.

I assume you mean exw.exe.
Please check the file size again.
77824 is at least 1K higher than anything I've ever shipped.
You might also try running:
ex sanity
in euphoria\demo to compute the checksums on the .exe's.
It's possible you've picked up a virus from somewhere
that has infected exw.exe (and probably other files) on your system.

Yes, sorry

Oops, that was 77824 used; I should have noted 75264 actual size.

passed 100%

Good call, however last night two different av scans with fresh avdb
found nothing.
If it is just me, not to worry. ;-(

I get the crash too. Someone with trace(3) should help.

Thanks, hopefully I saved someone some grief further down the line...

Erm. actually I didn't understand a word you just said so I (quickly)
checked this out and found on line 83ish (no line numbers in notepad):
constant HelpWindow = create( Window, "HotKeys", CalcWindow, Default,
Default, 419, 323, {WS_DLGFRAME,WS_SYSMENU,WS_MINIMIZEBOX} )
Or did you just hack into my pc and edit that file for me!?

Seriously, sadly it doesn't seem like you found the (non-urgent)
problem I have - which should be trapped by exw.exe & not "fixed" by
changing a .exw source anyhow. If it is a corrupt dll on my system I
can't afford to reinstall just now.

If you have a directory name :\Windows\sysbckup
this contains all of the dll's your system needs to run
properly. Although it's highly unlikely a dll is corrupt
you could copy these into you :\Windows\system
directory to be sure.

There seem to be two different crashes to investigate:
1. When starting calculate from the IDE, and, once you get that one fixed:
2. When closing calculate.
I'm using Win 98 and Derek's latest 55.5 version of Win32Lib.
In function fDoTVN_GETDISPINFO() around line 20,238 I get an error about
trying to access the 0'th element of a sequence. Here's my patch, which
may not be the right thing to do, but it gets us past the error:
-- This is called before we get the handle, so if
-- we haven't filled it in yet, we'll just grab
-- the first one.
if not lItem
then
-- lItem = find(0, tvitem_handle )
lItem = 1 -- IGM 01/12/2001
end if
Now, the program will run from the IDE, but will crash with a Windows
Meaningless Error* when closed. This can be fixed by changing the owner
of the HelpWindow from 0 to CalcWindow. Now it will run ok from the IDE or
directly.
Can anyone provide a "proper" fix for Win32Lib?

OK, I have hacked it down to the following:-
include Win32lib.ew
without warning
constant Calcw = create( Window, "Calc", 0, 78, 40, 246, 282, 0)
constant Table2 = create( PushButton, "9", Calcw, 74, 4, 30, 30, 0)
setHint( Table2,"9")
procedure screen_event( integer iMsg, atom lParam, atom wParam )
seq loc
loc=getRect(Calcw)
end procedure
onEvent[Screen] = routine_id("screen_event")
WinMain( Calcw, Normal )
-- If I comment out EITHER the setHint or the getRect It no longer
crashes when I close the window. I don't know enuf about win32lib yet
to trace it any further.
-- Does this close ok on your machine, Irv?

It crashes because the scree_event() tries to call
getRect() after Calcw is closed, which causes the crash.
Workaround is:
<CODE>
include Win32lib.ew
without warning
constant Calcw = create( Window, "Calc", 0, 78, 40, 246, 282, 0)
constant Table2 = create( PushButton, "9", Calcw, 74, 4, 30, 30, 0)
setHint( Table2,"9")
procedure screen_event( integer iMsg, atom lParam, atom wParam )
seq loc
seq info
info = getControlInfo( Calcw, {CONTROLINFO_closed})
if info[1] then
-- Calcw is closed, don't measure
return
end if
loc = getRect(Calcw)
end procedure
onEvent[Screen] = routine_id("screen_event")
WinMain( Calcw, Normal)
</CODE>
And it should be ok. However, this points to
internal bug in win32lib. (Assuming Bimtap just
by not validId(), which is wrong)
To fix it, change win32lib.ew to:
<PATCH>
in function getRect() around line 12130:
add at the top of the function (after var declarations) this :
if not validId(id) then
-- bad id (maybe say something?)
return {0,0,0,0}
end if
and replace
elsif not validId (id) then
by
elsif window_type[id] = Bitmap then
</PATCH>
Thanks for the report. I'll pass it to Derek.
N.B: Anyone know when will Derek come back from vacations ?
