While trying to retrieve https://www.bricklink.com/v2/catalog/catalogitem_pgtab.page?idItem=None&idColor=0&gm=0&gc=1&ei=0&prec=4&showflag=0&showbulk=0 I got the error “SP Error while getting price guide : INVALID PARAMETER” which means “data type mismatch” because ‘None’ should be a number
The documentation for the BrickLink API PushNotificationMethod suggests that the data sent to the URL you registered on the BrickLink API Consumer Registration Page is sent to this URL (via a POST verb, by the way) and as such you don’t need to call Get Notifications. Given the body of the POST is empty, this is not right – what you instead need to do is use any POST to your registered URL as a prompt to call Get-Notifications. It’s probably best to periodically call it too, given “it does not guarantee delivery of all events” and doesn’t either based on my experience.
A notification to be created when:
- You received a new order.
- Buyer updates an order status.
- Items of an order are updated (added or deleted).
- You received a new message.
- You received a new feedback or reply
Also note: NULL fields are not included in the returned JSON. Some fields names don’t match the documentation (eg: drive_thru_sent instead of the documented sent_drive_thru).
JWZ has observed he now mostly programs because of things that piss him off.
If you’re just mucking about with IIS, you don’t really want to pay a CA to get a legit certificate, do you?
Just don’t even think about using it in production code.
Oh, and don’t get the page to email you the certificate to a mailbox you can only look at via Outlook. Outlook’s dumbarse “protecting you from shadows” attachment filter won’t let you at the CER certificate file that comes through.
I had a program that was crashing at the customer site, but not in any way I could reproduce back at the office. I wasn’t able to load up a dev environment on the affected box, but someone had the bright suggestion of running Dr Watson (DrWtsn32.exe), and checking out the stack trace. As we all know, if you know your codebase well enough, you can almost explain a crash just by where it happened.
So I created an exe with debug symbols and optimizations removed, and waited for the crash. The DrWtsn32.log contained, amongst other things, the dump of the thread that caused the program crash:

Which added nothing to my understanding of what went wrong, beyond it happened at some point after the thread started. Great. Did I mention I’d done a debug build – the kind with all the symbols compiled in? Anyway, I figured switching to the binary output (which I understand is like a unix core file) may provide further explaination.
The format of the binary output from Dr Watson is lost in the mists of time. I had to go to an NT4 server install CD (you have to love the pack-rats who keep the German Server version of NT4 ©1999!) to locate the two necessary files for working with the user.dmp file it generates. The files are DUMPCHK.EXE and DUMPEXAM.EXE.
Running DUMPCHK.EXE gives a little output
C:\...\RetailGateway>dumpchk user.dmp Filename . . . . . . .user.dmp Signature. . . . . . .USER ValidDump. . . . . . .DUMP MajorVersion . . . . .5 MinorVersion . . . . .0 DirectoryTableBase . .0x0000014c PfnDataBase. . . . . .0x00000004 PsLoadedModuleList . .0x00000018 PsActiveProcessHead. .0x0000009a MachineImageType . . .NumberProcessors . . .7528 BugCheckCode . . . . .0x00001f65 BugCheckParameter1 . .0x000000a0 BugCheckParameter2 . .0x00000040 BugCheckParameter3 . .0x00001ca8 BugCheckParameter4 . .0x00d6df65 ExceptionCode. . . . .0xc0000005 ExceptionFlags . . . .0x00000000 ExceptionAddress . . .0x0045b4a9 ExceptionParam#0 . .0x00000000 ExceptionParam#0 . .0x00000000
At which point I got this dialog:
“Oh well,” I thought, “I’ll just head on straight to examining the dump, rather that checking it.” Unfortunately, DUMPEXAM.EXE wasn’t on my side. All I got was:
C:\...\RetailGateway>dumpexam user.dmp unsupported processor type
Which is useless. Which is the sum value of the binary dump from Dr Watson. And, in this case, all of the output from Dr Watson.
