Chris, cg> Using Compiler.Compile *\f on PC = PC = 7583 & 5551 Is this the trap from the gif image? Otherwise, can you narrow down the html source to where you understand what is instigating the problem? ... Peter E. http://carnot.pathology.ubc.ca/

n-o trap analysis confuses me

We're running out of excuses for > fixing some of the problems! > The previous problem which I reported is/was that I suddenly had TRAP -14 for all Desktops.OpenDoc "http://www*" Well, I had a power-outage and a 'Windoof' aka reboot. And after that no more problem. But I've had this problem for months between reboots. My immediate [superficial] guess is that it is related to the heap 'load', since I normally have a week or 2's work load between re-boots. Using Compiler.Compile *\f on PC = PC = 7583 & 5551 , [on a sytem which no longer traps] based on: TRAP -14 NIL reference ( 00000014H ) (PC Native 11.10.2001) HTMLImages.ImgIcon PC = 5551 key = 53 keyAttr = "IMGKey" HTMLImages.IMG PC = 7583 C = 00000018H E = 0044EB80H P = 0014C7E0H S = 000000A8H alt = "Valid HTML 4.01!" attr = "" battr = 00000000H border = 0 doc = 00000000H led to confusion. Examining the small PROCEDURE ImgIcon [below] led to a first guess that C was not initialised, so I manually traced were it was [to be] initialised. Although the trap-trace shows C as non-zero ? Here's the skelton as I see it [with 1,2,3,4 being the execution sequence]:- { pity you can't see in colour - don't you just love n-o ! } PROCEDURE IMG(VAR S: HTMLDocs.Scanner; on: BOOLEAN); VAR ......... C: Objects.CopyMsg; PROCEDURE ImgIcon(keyAttr: ARRAY OF CHAR; key: LONGINT); BEGIN doc := NIL; obj := Gadgets.FindPublicObj("Icons.Picture"); Links.GetLink(obj, "Model", obj); C.id := Objects.shallow; Objects.Stamp(C); 3 C.dlink := NIL; C.obj := NIL; obj.handle(obj, C);<-- Compiler.Compile *\f NEW(iCon); E.obj := iCon; iCon.entry := E; Rembrandt.NewP(iCon, C.obj(Pictures.Picture)); icon := iCon; icon.handle := IconHandler; Attributes.SetInt(icon, keyAttr, key); Attributes.SetString(icon, "Cmd", "HTMLImages.LoadIMG") END ImgIcon; 1 BEGIN <-- IMG ... IF ~HTMLDocs.imgs OR (doc = NIL) THEN 2 ImgIcon("IMGKey", ikey); Attributes.SetInt(icon, " ^^ calls the trapping proc ..... 4 Pictures.ReplConst(C.obj(Pictures.Picture), Display.BG, .. ^^ before variable C is *accessed* [never mind initialised] !! ..... END IMG; ------ It seems to me that C is not initialised in either of the 2 Procs. before it runs the trapping statement [in PROCEDURE ImgIcon]. BTW at this stage, I'm less worried about the trap-cause than debugging the flaw(s) in MY logic. It may be relevant that the same statement pattern as that calling the trapping proc, is commented out further up in the calling proc: PROCEDURE IMG. See: IF ~HTMLDocs.imgs OR (doc = NIL) THEN ImgIcon("IMGKey", ikey); Attributes.SetInt(icon, "OBJKey"...

NO 11.10.2001: Trap HTMLDocs.WriteCharRef
by edgar＠edgarschwarz.de 24 Mar '04

24 Mar '04

Hi Chris, MM http://www.debian.org produced the following trap which also Peter E. reported (Even with a later NO it seems) Peter E. wrote: > TRAP 7 Index out of range (PC Native 05.01.2003) > HTMLDocs.WriteCharRef PC = 17182 > P = 00492880H > S = 00000010H > entity = "" So I still have to find the old source zips on my archive CD and copy them to the 486 machine. A trap 7 shouldn't be a big problem BTW. But that's for another day. But perhaps you should at least move to the newest NO sometime. Nevertheless, I have a 11.10.2001 installed now so I can have a look. BTW, I'm also working on WebDAV. At the moment porting the server to WinAos 1.06 is some work because the file concept of Windoof is different from Oberon. Cheers, Edgar

Chris, cg> HTMLImages.ImgIcon ... cg> Have you got an 'image' at the end of you web-page ? Yes, validhtml401.gif which advertises HTML validity. My first guess at an explanation for the trap is that PC Native 11.10.2001 preceeded gif support. Try PC Native 05.01.2003. cg> Like I'm the only person in the world still using 486 machines ! A 486 made the page at http://carnot.pathology.ubc.ca/. Finding the source of my trap from http://www.debian.org/ is a good exercise. First, note that http://validator.w3.org/ reports that the page is valid HTML 4.01 Transitional. Save the html text to a file. Near the end of the text is a series of language specific references following "This page is also available in the following languages:". Remove all the language reference lines except one. With some lines the page opens without a trap. The Norwegian line for example. Other lines raise a trap. Eg. the Japanese line. Seems that Desktops.OpenDoc can not cope with a few of the characters invoked. This suggests again that Desktops.OpenDoc needs a little work on html character references. Just in case anyone is bored ... cg> As one who grew up with 8 bit CPUs, I still find it unacceptable to see CPU's with 'air-conditioners strapped to their back !'.

Bluebottle 3Com90x Ethernet card
by Necati Ecevit 23 Mar '04

23 Mar '04

Hi, I installed latest Bluebottle OS (March 2004) version succesfully. I have 3C905 100Base TX [Boomerang] vendor/device: 10B7 / 9050 card on this PC. The problem is that my internet connection does not work with this card. I tried with 3C90xMedia=7, 3C90xDuplex=1and other combinations in Aos.Par file, and the result is negatif. I can ping my localIP from this machine. BB installs this driver with no errors. But I can not ping, browse an outside ip, and from outside I can not see this machine. With this card and previous Jan 2004 release of Bluebottle, internet connection was working. With 3C905B card on the other machine and latest BB release everything is ok. What could be the problem? could you help. Best regards, Necati Ecevit.

As Edgar noted, in case HyperDocs.Tool is ever updated, it might list two instances of Fetch. HyperDocTools.Fetch Local.Doc ~ Download the selected link to Local.Doc. HyperDocTools.Fetch Doc => Local.Doc ~ Download Doc to Local.Doc. Also, Chris G., about a month ago you mentioned a trap from "Desktops.OpenDoc http://...". Try "Desktops.OpenDoc http://www.debian.org". Head of trap is appended. Is this another font problem as you mentioned months ago. Any connection to your trap?
