Active Directory lookup
by Greg Keogh May 25, 2024

May 25, 2024

TGIF! I just spiced-up an ASP.NET app so that it uses DirectorySearch.FindOne <https://learn.microsoft.com/en-us/dotnet/api/system.directoryservices.direc…> to either verify a login user account exists or to authenticate. It runs perfectly on my work PC, but when I installed the app in IIS on my test server it died with *The specified domain either does not exist or could not be contacted*. I discovered that because my app was running as NETWORK SERVICE, which isn't a domain user, it can't see the Active Directory. A trap...only domain user accounts can *see* AD. Asking the customer (a hospital) to create a special account, assign it to the pool and set ACLs is impractical. My lovely new login feature has hit a roadblock and I'm not sure of a workaround or alternative. It's a specialist topic, but I thought I'd ask in here just in case some boffin has suggestions. *Greg Keogh* P.S. I just remembered that about 15 years ago I used a Win32 Interop to call LoginUser <https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-logo…> for a similar purpose, but it was for local accounts and I'll need to research if it works for domain accounts.

CPU profiling an MS unit test
by Greg Keogh Feb. 22, 2024

Feb. 22, 2024

It's not Friday, but I can't find any way of running the CPU performance profiler over a [TestMethod] in my unit test project. Web searches produce no useful results, some hint that I can right-click a test in the test explorer and pick Profile..., but I have no such menu. Is this possible or not? If so, what's the trick? P.S. I often use the profiler for commands or GUI apps, but in that case you set breakpoint #1 and start the profiler, then at breakpoint #2 you stop it and collect the results. That doesn't work for a unit test method (so far...). *Greg*

Private Apple App distribution
by Greg Keogh Jan. 18, 2024

Jan. 18, 2024

Folks, We're planning a MAUI app to be installed on company Android and Apple phones. For Android I can just generate the APK file and side-load it (after the security settings are relaxed). I don't know how to do the same for iPhones. We don't want the app in the store. Assuming there is a convention for "side-loading" Apple apps, what's the technique? Is anyone doing this? A few years ago we published a Xamarin app, but it was for the public and was published in both stores. This time the app's private to the company. Thanks, *Greg Keogh*

Web app large uploads and downloads
by Greg Keogh Jan. 4, 2024

Jan. 4, 2024

Folks (anyone working?) I've been asked to add a feature to a Blazor Webassembly app to allow uploads and downloads of possibly large numbers of files between the local file system and Blob storage. I'm not sure how to implement this feature in a browser hosted app. I wrote a WPF tool for "managers" which does high-performance bulk uploads and downloads with nice progress (the code is trivial on the desktop), but now they want the same feature for "normal" users in the Blazor app. Given how dumb and restricted browser hosted apps are, I don't know how to code this, or if it's even feasible. Are there some tools, techniques or tricks I can apply? Any ideas or suggestions anyone? Thanks, *Greg Keogh*

[OT] Contracting PAYG vs ABN
by Tom P Dec. 11, 2023

Dec. 11, 2023

Hi all, I’m getting asked by a recruiter whether I want to do PAYG or use a personal ABN for a contracting position. I never really understood why one would use an ABN as you’d need to get your own insurances etc. Can anybody explain? Cheers Tom

Conditional builds of arbitrary files
by Greg Keogh Dec. 5, 2023

Dec. 5, 2023

Folks, the MSBuild process provides Condition= and #if to provide lots of control over which files and code fragments are compiled and published for a given Configuration. My projects contain increasing numbers of non-cs files like html, css, js, txt, etc which often need conditional processing, especially the equivalent of a #if to select fragments of those sorts of files for different configurations. There's no way to select fragments of arbitrary files with a #if, so I've been wondering for years about the best way to simulate the feature. I can't find any tools to do this, so I *think* that a custom MSBuild Task might be the way to go. The task could be given some parameters and it would edit the files and add and remove sections based upon the configuration before the build starts. Does anyone think that's a good idea? Or maybe there's a better way. Cheers, *Greg Keogh*

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*
