Blazor css overrides
by Greg Keogh Dec. 4, 2023

Dec. 4, 2023

Folks, TGIF Our Blazor app has a simple classic shape with a local wwwroot/app.css file containing all the styles for the app. I had to allow people to customise the appearance, and my way of doing that works, but not as smoothly as I hoped and I think someone might be able to suggest a better more elegant technique. If someone starts the app with query parameter ?t=contoso then the startup code appends a line like this into the <head> <link rel="stylesheet" type="text/css" href="https://*somecompany*. blob.core.windows.net/*myapp*/*contoso.css*"> They can edit this external css file and override selectors without touching the original app's files. Firstly ... is this sensible? It works, but there is a problem. To override a certain colour they have to code something like this: .HeadLinkSel { background-color: BlueViolet !important; } Note how the !important is needed, sometimes. I can't figure out why yet, but !important needs to be added to the overrides most of the time. I thought that the last selector override all previous identical ones, and it's really irritating and confuses people settings the overrides. Can anyone explain this? Maybe my whole technique is flawed and naïve. I'm keen for suggestions or links to recommended techniques for doing this sort of thing. Cheers, *Greg Keogh*

[OT] Identifying domain details
by Greg Keogh Nov. 28, 2023

Nov. 28, 2023

Folks, I'm preparing the paperwork to take some fraudulent plumbers to the Magistrate's Court for "recovery of civil debt". Background information is on my web page SCAM - KM Heating & Cooling <http://www.orthogonal.com.au/specproj/km-heating-cooling.htm>. As part of the case I'm going to ask if an order can be made to shut down the matching fraudulent website at kmheatingandcoolingplumbers.com.au and (hopefully) have the domain registration cancelled. Can any network boffins in here tell me what identifying whois and similar domain information can be extracted for me to add to the case? *Consider replying to my personal email because this is not of further interest to the group.* Cheers, *Greg Keogh*

Minimal Web API code helper package
by Greg Keogh Oct. 30, 2023

Oct. 30, 2023

Folks, a couple of weeks ago I was watching a video where someone used a NuGet package in a minimal Web API project to change the plumbing slightly so that it was easier to code the endpoint methods. By default, the endpoint methods must be strictly coded and it's tricky to break them apart or make partial methods. The package I saw added some magic to make coding the endpoints easier, but I can't remember exactly how. I just remember thinking "that looks handy" and now I can't find it. Any idea what it might have been? *Greg Keogh*

AEC form
by Dr Greg Low Sept. 16, 2023

Sept. 16, 2023

Whoever develops code for the AEC really needs to take a long hard look at themselves. Second error is the Captcha failing even though it didn't ask for it in the first place. It wasn't visible on the form. And I'm not sure what attempt at English the other error is meant to be. Does anyone review this?

Is anyone here actively using Blazor on a decent sized project? I used it for a while on my last contract but am unable to find new work anywhere that uses Blazor, not a single one! Thoughts? Tom

A real C++ vs C# story
by Greg Keogh Sept. 1, 2023

Sept. 1, 2023

Folks, it's Friday and I have an anecdote to share before I return to today's coding fiasco. I'll just tell you what happened and try to avoid making judgements, I'll leave that to you. For about 4 years we've had an Azure hosted Web API/service driving a moderately complex Blazor app and some other smaller clients. The service hosted a C++ library that did the heavy lifting of generating cross-tabulation reports. The trouble was, that the service would randomly crash deep inside the C++ dll and it would leave no useful diagnostic evidence, usually just a hint about some kind of memory access violation. It would never crash in testing, only in Azure. I presume here is a way to diagnose this sort of crash in Azure hosting, but you probably need the minidump and symbol files out of the C++ compile, I'm not exactly sure, as I just couldn't face the toil, and by great luck it was due for replacement anyway. Some very large US companies were suffering from the crash interruptions and there was a serious risk that we could lose their business. The lucky part is that the huge C++ codebase was already being rewritten in C#, so we went into a frenzy of continued conversion and testing, and the C# replacement is now about 90% rolled-out. and guess what?! ... The random crashes are gone and one customer even sent us a message of thanks for the new reliability. We did have a few small unhandled exceptions, but I simply went to the Azure portal logs and the stack trace pointed us straight to the problem point. We could usually publish a fix within half an hour. So years of random C++ crashes were completely cured by a C# rewrite. *Greg K*

Web app deploy without Visual Studio
by Greg Keogh Aug. 21, 2023

Aug. 21, 2023

Folks, I have a Blazor app and a Web API that I need to "give" to someone to install in their own Azure subscription. I have only ever published to Azure from Visual Studio via right-click and make some publish profiles. In other cases I would create a Web Setup project and give someone an MSI file, but I doubt if that's useful for deploying to Azure. I've been searching and searching, but most results talk about Visual Studio publish, and a few talk about using DevOps pipelines, but none of those are suitable because the customer has a personal Azure subscription that I can't access. Is there some dotnet command switch to generate some kind of "package"? Maybe there are other options I haven't stumbled on. Thanks, *Greg Keogh*

SQL Server Performance monitoring
by Greg Keogh Aug. 3, 2023

Aug. 3, 2023

Folks, We have a problem on a live server where web users experience occasional unpredictable "stalls". There are a few links in the chain where the problem could be, but based on some clues in logs, I suspect that it's the last link at the bottom of the chain ... SQL Server that's the source of the problem. But I need evidence. Is there some feature of SQL Server or perhaps some tool that can detect queries that are suspiciously long running? This is SQL Server full standard edition. I haven't had to poke deeply into SQL Server's machinery before, so I'm in unfamiliar territory. Cheers, *Greg Keogh*
