Hi Don
Not sure what this has to do with your computer crashing, but it looks like the line 's = ( s = ' ' )' is evaluating to TRUE or FALSE, and trying to set s to either of these values is balking at this, unless your crash corrupted win32lib. Look at what variable type s is.

I think you should just reinstall your win32lib.ew files. There is no such line in mine.
What SVN version is that?
I use an svn checkout:
https://win32libex.svn.sourceforge.net/svnroot/win32libex/trunkversion 68.
I had a few problems but nothing like this one.

Run Edita/Options/File Extensions and look for exw. If my suspicions are right, it says pw.exe: change it to exw.exe. Edita ships with an old public domain 2.4, or use browse to locate r3116 or whatever.

Sorry, I suddenly felt it was out of date, misleading, and inappropriate. I've put a more permanent copy of that text here http://edita.isgreat.org/phpBB2/viewtopic.php?f=1&t=28

Thank you, Chris, SDPringle and Pete,
I upgraded to win32lib 0.70.4a.
Whin I put the old exw.exe under file extentions in Edita everythings works fine.
When I put "E:\Program Files\edita\pw.exe" I get:
e:\eu\win32lib\win32lib.ew:4421
pText = Text
^ type error

Looks like you (/Phix) found a minor bug in win32lib.
I see:
4414 global function ansiUpper(sequence Text) -- added R. Stowasser 4415 sequence upperText 4416 atom pText 4417 4418 if sequence(Text) then 4419 pText = w32acquire_mem(0, Text) 4420 else 4421 pText = Text 4422 end if
and slightly earlier:
4392 global function ansiLower(object Text)
obviously ansiUpper's parameter should likewise be object, not sequence
I will try and do some tests on 0.70.4a in a couple of days time.
Regards, Pete

... obviously ansiUpper's parameter should likewise be object, not sequence
I've fixed this now in the sourceforge SVN for win32lib.
NOTE: When the parameter is an atom, it is assumed to be the address of a null-terminated string in RAM and not a single character to be converted.

For ASCII, surely a check for (integer(Text) and Text < 256 and Text > -1) is enough to tell if a given atom is a sngle character or a pointer to RAM?
If these functions support UTF-16 then this is not possible, of course...

I'm just reporting what is does do and not what it could do.

That's reasonable. I was just wondering if there was a really good and very important reason for the lack of that capability that I had missed or if it was just something that needed a programmer to code up or etc.

I don't know. I didn't write the functions nor are they needed in the new Win32Lib.

I found several errors like this I will post when I finish.

Sorry Don, I disagree with most of these. Have a look at my mods (all marked PL 02/05/10) available at http://uploading.com/files/7mm38ac5/Include.zip
See also http://oe.cowgar.com/forum/111355.wc?last_id=0
I will happily expand on any of these, but one at a time, OK?
win32lib.ew line 4622 word should be object
disagree.
w32resources.ew 3485 global function textToBitmap( sequence s ) s should be object global function textToBitmap( object s )
disagree.
w32resources.ew 5230 procedure setMousePointer_( object id, atom handle, integer flag) sequence lKids,lCursors should be object lCurors
Unlikely to be the right thing to do. lCursors is passed to:
procedure setCursorInternal(integer id,sequence data)
I just put a ?9/0 in place of that lCursors=handle line, since it would have crashed there on RDS Eu every time anyway.
w32resources.ew 5472 maskbits should be object
disagree.
w32resources.ew 4064 image should be object
disagree.
win32lib.ew 9316 id should be object
Probably.
win32lib.ew 12532 attribs should be object maybe integer
Not sure about that one. It is definately used as a sequence, sometimes:
attribs=repeat('i',count)
win32lib.ew 18133 line should be object
agree. (Yeayh! 
)

win32lib.ew line 4622 word should be object
I don't have anything like this in my win32lib.ew. Line 4622 is ...
cts_preallocated += SIZEOF_POINT
which is in
global function ClientToScreen(integer id, integer x, integer y)
w32resources.ew 3485 global function textToBitmap( sequence s ) s should be object global function textToBitmap( object s )
Why? The purpose of the routine is to take a text string, in which SPACE represents a black pixel and NON_SPACE represents a white pixel, and convert that into a monochrome bitmap image. Passing an atom to this routine makes no sense.
w32resources.ew 5230 procedure setMousePointer_( object id, atom handle, integer flag) sequence lKids,lCursors should be object lCurors
Yes, this can cause a crash. However, instead of changing the datatype, which just masks the problem, the routine needs to be written better.
w32resources.ew 5472 maskbits should be object
I don't think so. 'maskBits' needs to be the same datatype as the 'image' parameter, which is a sequence. And that needs to be a sequence as it is a monochrome text 'picture' of a mouse pointer you wish to create.
w32resources.ew 4064 image should be object
I don't think so. 'image' is a set of sequences so must be a sequence. An atom here makes no sense at all.
win32lib.ew 9316 id should be object
Agreed. This is a bug. As it stands, setParent can't be used with ListViews or TreeViews.
win32lib.ew 12532 attribs should be object maybe integer
I don't think so. 'attribs' must be a sequence because it is initialized using the 'repeat()' function whose output is always a sequence. It is supposed to contain zero or more elements, one per item in a ListView.
win32lib.ew 18133 line should be object
I'm not sure which routine you are referring to here, but all the line symbols around this seem to be the correct data type. Why do you think otherwise?

FYI, I believe he is referring to
global function controlStyle(integer id,object flags,integer extended,integer action)
in which my recommendation is
sequence words --(as is) -- kludge: and_bits() only works on integers, not on atoms representing machine integers --PL 02/05/10 --/**/ words=sq_and_bits(w32unpack_dword(oldFlags),w32unpack_dword(flags)) --/* Phix words=and_bits(w32unpack_dword(oldFlags),w32unpack_dword(flags)) -- RDS */
Thanks, I can tick that one off now.
win32lib.ew 12532 attribs should be object maybe integer
I don't think so. 'attribs' must be a sequence because it is initialized using the 'repeat()' function whose output is always a sequence. It is supposed to contain zero or more elements, one per item in a ListView.
The problem line, in procedure handleLV, is
attribs=-2
win32lib.ew 18133 line should be object
I'm not sure which routine you are referring to here, but all the line symbols around this seem to be the correct data type. Why do you think otherwise?
I believe he is referring to
global procedure deleteLine(integer id,integer line)
which I accidentally changed to
global procedure deleteLine(integer id,sequence line)
though I really meant
global procedure deleteLine(integer id,object line)

Are you talking about the Win32lib used with Euphoria or with 'Phix'?
This is a Euphoria forum.
The use of attribs in handleLV() is a mystery to me. In my opinion, the code that CChris wrote for win32lib is of a poorer quality than should have been allowed in production.

Correct. I already deleted post 5 because it was inappropriate. I have also already created a new thread, http://oe.cowgar.com/forum/111355.wc?last_id=0 which is intended to be solely about win32lib on RDS Eu.

While I don't disagree with the sentiment, a lot of the ListView stuff (which appears to be what Derek is referring to) was probably originally written by me, back when I little understood win32lib or the Win32API itself. That's not to say that CChris couldn't have messed up my brillant code! :P
