Is Blazor client-side debugging possible or what is that experience like?
Blazor is new to me. I've used Razor / MVC significantly in the past but moved on to other technologies. Checking it out now, Blazor is definitely an improvement and seems to replace Javascript with dot NET. One of the things mentioned is it can run on the browser. My question then is: how is the client-side debugging experience in Dev Chrome Tools?
One of the Blazor videos in checking out:

Your browser's developer tools aren't going to be particularly useful when debugging Blazor apps. Here are the types of messages you'll see in the console.
The code running the browser is WebAssembly, compiled from C# or other .NET language. WebAssembly is binary, so you're not going to be able to debug that in your browser. Instead, you'd want to debug the .NET language in an IDE (Visual Studio, VS Code, etc.).
We need to play a 3D viewer in our delphi 10.1 application. For this we are using Delphi TWebBrowser component to emulate browser. But TWebBrowser in Delphi does not support WebGL. Is there any way to overcome this issue?
Instead of TWebBrowser component which encapsulates Internet Explorer, you could use Chromium Embedded Framework (CEF).
But then you have to ship your app with additional DLLs, just to keep that in mind.
See here vor V3 or here for V4.
I'm looking at Delphi web server apps, and the first thing I notice when I go into the New Items dialog is that there are several different frameworks.
WebBroker looks the nicest from a conceptual standpoint, but in the documentation it looks like its DB and session-management code is tied to the BDE, which makes it somewhat less than useful today.
WebSnap looks very similar, but the documentation says it's deprecated and IW ("VCL for the Web") should be used instead.
So I look at IW, and I can't make heads or tails of how it's supposed to work. The sample code is full of stuff that looks like it belongs in a desktop app, like clicking a button to fire an event handler to change the caption of a form element. (Wouldn't that have to be done client-side in JavaScript if we're creating a webpage?)
So what's the current standard framework for building a web server in Delphi?
While there are several commercial options available for writing web apps with Delphi, in my opinion Delphi no longer ships with a modern web development solution included as part of the package.
If I had to give an answer to your question though I would say that the current out of the box Delphi web framework is WebBroker. WebBroker is the only web framework included with Delphi that isn't deprecated or restricted in its functionality.
WebBroker was introduced perhaps as far back as Delphi 4. It's a good honest work horse but it hasn't really been improved much since it was first introduced. It leaves you to do most of the heavy lifting but it also doesn't get in your way. WebSnap and IntraWeb were built using WebBroker as their foundation which gives you idea of the level of services it provides.
A full version of IntraWeb has been bundled with Delphi Enterprise for many years but as of Delphi XE it now has several limitations (no SSL, no ISAPI deployment, 20 minute idle timeout) that will very likely mean you'll need to buy a license from AtoZed to use it seriously.
The version of IntraWeb bundled with Delphi Pro has always been far too limited to be considered anything other than an evaluation version.
Old question but still deserves an up-to-date answer.
Current 'settled in' solutions are:

Introduction
uniGUI Web Application Framework extends Web application development experience to a new dimension. uniGUI enables Delphi developers to create, design and debug web applications in IDE using a unique set of visual components. Each component is designed to provide same functionality of its counterpart visual component in Delphi VCL. This provides a very comfortable development environment very close to native VCL application development with an easy learning curve. uniGUI Web applications can be deployed to a server using one of the available deployment options such as Windows Service, Standalone Server or ISAPI Module.
Product Highlights:
Based on industry's most advanced JavaScript library Sencha Ext JS.
Includes OEM license for Sencha Ext JS. (Please see licensing for details).
A unique platform to create stateful web applications.
Complete IDE support for creating projects, designing forms, frames and handling data modules.
Advanced support for scripting client side JavaScript events.
Library core is fully optimized to achieve highest level of scalability.
Including advanced Stress Test Tool utility.
Comes with various deployment options: ISAPI Module, Standalone Server and Windows Service.
Supported Delphi versions: Turbo Delphi Pro, Delphi 2006, Delphi 2007, Delphi 2009, Delphi 2010, Delphi XE, XE2, XE3, XE4, X5, XE6, XE7, XE8, Delphi 10 Seattle, 10.1 Berlin, 10.2.3 Tokyo and 10.3.3 Rio (Win32 & Win64 platforms). (Linux support is in the roadmap)
C++ Builder supported.
Supported Browsers: IE 9+, Microsoft Edge, FireFox, Chrome, Safari and Opera

http://docwiki.embarcadero.com/RADStudio/en/DataSnap_Overview_and_Architecture
DataSnap has been there for a long time, and the latest releases is DCOM-free. You can utilize it to build up server side piece (S in both C/S and B/S). Its current role is almost like WCF in .NET world.
Then if you are building a web site front end, you can use IW. But DataSnap makes it even possible to build up front end using PHP or other web technologies.

PascalWeb use pascalscript compiler , you can create web app, like php or python
I am coding an add-on using an existing SDK which has no webview-like component but allows for ActiveX controls.
So the only idea I come up with is find an ActiveX control implementing a web browser or at least show a web browser.
Is there such control?
Don't use the IE activex control, it's full of memory leaks.
See this post for alternatives:
Replacing .NET WebBrowser control with a better browser, like Chrome?
FireBreath has a WebView library that uses the IE activex control to embed a web browser inside a FireBreath plugin (which acts as an ActiveX Control on IE). You should be able to adapt it, assuming you're using C++.
Finally find it.
SHDocVw.WebBrowser will do.
Usually the path is C:\Windows\System32\shdocvw.dll
I have a shared hosting for asp classic, i am using an activeX dll in my asp script. ASP page works fine when i register the ActiveX component, i am using CreateObject function, but on live shared hosting i can't register my ActiveX component. Any idea how to use ActiveX component in shared hosting.
You have to ask them to install it at the server. Most probably they will not ;)
