Customisable web app styling
by Greg Keogh Aug. 5, 2025

Aug. 5, 2025

Folks, I'm trying to find the "best" way of allowing different customers to style their own hosted version of our web app (actually a Blazor net8.0 app). For years we hosted a single global copy of the app in our Azure subscription where multiple customers would use it. It has a single line for the app's styles: <link rel="stylesheet" href="app.css" /> When customers deploy the app in their own subscriptions it would be great to leave the default app.css file untouched but allow them to easily override any style elements they like. What's the best way of doing that? Do I simply append a line like: <link rel="stylesheet" href="{some customer uri}/custom.css" /> Do styles in that link override any identical ones in the previous one? I'm not sure of the cascade order or conventions. There might be better techniques I'm not aware of. Thanks, *Greg K*

XAML images in WPF?
by Greg Keogh Aug. 1, 2024

Aug. 1, 2024

Folks, in a video I saw a few weeks ago I learned that the Visual Studio team uses XAML for most of their images, not png or similar. I'm keen to do the same because I imagine that I would no longer need tedious sets of 16x16 32x32 48x48 ... etc images because each XAML file is composed from scalable geometry elements that would look good at any size. I downloaded the Image Library <https://www.microsoft.com/en-us/download/details.aspx?id=35825> which contains thousands of XAML, png and svg sets of standard images. But I can't figure out how to *simply* use the XAML files in a WPF app. All the examples I can find seem to have pasted the contents of the XAML images into resource files and then reference them by x:Key. I don't want to manually paste XAML around like that, I just want to add a file like *FolderClosedBlue.xaml* (for example) to my project and use it as the icon for a menu or button as simply as possible. How can I replace this sort of thing?... <MenuItem Header="_Foo Command" Command="..."> <MenuItem.Icon> < use the XAML image file somehow instead of a resource png? > </MenuItem.Icon> </MenuItem> Is there some coding trick I'm not aware of to *simply* use an image defined in a XAML file in my app? Cheers, *Greg K*

Re: AI [GitHub Copilot]

Hi Tom et al, Coincidentally, my CoPilot trial ends today and I've decided to let it continue at $US10/month. So my AI qualifications now begin with one month of GitHub Copilot. Is this particular AI useful for developers? Urrrr...sort of...I've got mixed feelings, but I'm going to let it run for some more months and see how it goes. People in demos everywhere, even many of the top boffins have it running in their videos, so if it's good enough for Mads and Anders then I like what they like. Sometimes Copilot throws out suggestions that are jaw-droppingly psychically predictive and I stare in disbelief before hitting tab. Other times it produces something completely irrelevant that was snipped from a different project I was previously working on. The former seems to outnumber the latter, so that's why I'm continuing the subscription. As Tom hints, I also probably get a 1-2% boost in productivity thanks to Copilot (well, I will when my reflexes adapt to stop having keyboard races with it). I feel the name "AI" is a bit generous, as it's clearly just trawling through vast amounts of code and samples, analysing it and spitting fragments back out at you based on patterns and context. There are fabulous algorithms at work finding patterns, but is this "AI"? When I first saw the movie *2001: A Space Odyssey* in 1969 I was fascinated by HAL (I was clearly destined to work in IT!), and now 55 years later I'd like to be able to sit down with HAL and explain some complex business requirement to him, converse like professionals and weigh-up the pros and cons of different platforms and languages based upon his world of experience and get him to code like a 1000x developer and generate a complete working skeleton of the required product. When will I see that? I'm a bit disappointed so far. Oh well, back to coding with my Copilot buddy. *Greg K* On Sun, 28 Jul 2024 at 23:19, Tom Gao via ozdotnet <ozdotnet(a)ozdotnet.com> wrote: > Hey Guys, it's been awhile since I've asked the question about the > usefulness of AI in our development world - for a seasoned senior developer > for a complex digital transformation project.

AI
by Tom Gao July 30, 2024

July 30, 2024

Hi guys, I haven't posted in a few years and haven't been on the tools for a long time now as well. I'm on a panel on a digital conference coming up in march. We had a pre meeting today and the topic of AI came up. Two of the panelist said cited CBA and Westpac using AI and were able to save 30% on development effort. Personally I just finished an AI course my view is quite the opposite. My personal opinion of the generative AI space and AI in general having spent time with the academics is that the benefits are significantly over inflated. I want to get some other opinions if you are seeing any significant benefit and that I may be just out of touch or not aware. Thanks, Tom

[OT] Windows Server install problems
by Greg Keogh July 18, 2024

July 18, 2024

Folks, it's been a non-TGIF day. My old server under the desk running Server 2019 (or 2016 I forget) died this morning and I'm trying to create a replacement I have a brand new *one of these* <https://www.ple.com.au/Products/665032/ple-midnight-gtx-1650-prebuilt-ready…>, so I installed Server 2019 and it all went smoothly until it booted and all chipset devices are dead, including the network adapter and the screen is stuck at SGA. The only drivers I can find are for Windows 7 to 11 and nothing else. I tried installing 2016 as an experiment but it produces the same results. Am I wasting my time? Is that box incapable of running recent Windows Server editions? *Thanks, Greg*
