I'm using delphi 2010, and in order to create components i'd like to see the source of delphi components such TEdit, TButton... But the problem is this option is unavailable in my IDE, the type of any added component is written in black (and not in blue so i can see the source). So how can i get this option?
Thanks for your replies.
You seem to be using either a trial version or starter edition of Delphi. The source is deliberately not available. You would have to acquire / pay for a higher edition of Delphi, such as Pro, Enterprise, Ultimate, or Architect.
If you wish to study how components / controls work, find a popular third-party one. For example, I've been experimenting with Chrome Tabs lately.
I think pbear's component HTML Components, v 9.45, is just what I need. His free download only has packages for Delphi 2006 and earlier. I have Delphi XE. How would I install his components into my Delphi?
Try this Google code download site THtmlViewer.
Seems to be updated to XE2 version plus Lazarus.

Have you considered using Delphi Chromium Embedded? This is the Delphi API for Google's Chromium, which is used by the Google Chrome web browser. Several Delphi versions are supported, including XE and XE2.
Unless you only need rudimentary browser support, it makes sense to use an up-to-date browser with solid support for modern web standards.
The repository includes Delphi sample projects for VCL and FireMonkey.
I am working on a big legacy application written in Delphi. Most of the components are VCL and DevExpress QuantumGrid components.
I would need to update the UI to support various styles and a more modern look and feel. Originally
I was planning to switch to the DevExpress ExpressSkins library (I already have the full DevExpress VCL subscription) and replace all components with DevExpress components. However since than I have upgraded the project to Delphi XE2 and with it came the VCL Styles technology.
What are the pros and cons of these libraries?
I haven't used VCL styles because I too have Dev Express and like to use their skins. But here are my two cents for DX skins.
Pros for DX skins:
look great
always coming out with more skins
styles chooser widget built in for the end user, if you use the DX ribbon in your app
DX has great support for their components
Cons for DX skins:
unusable in a Citrix or Terminal Services environment due to slow screen painting
each skin adds an entry to your USES clause which can be cumbersome for version control
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:

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.

What is the process of converting win32 application (a small popup window actually) to win7 gadget?
Do I need to convert my exe to activex component, can I still use TForm ?
it would be nice to have support for both Win7 + Vista.
The Windows Vista/7 gadgets are essentially mini-HTML applications. The user interface is composed of pages containing regular HTML, CSS ,images and potentially ActiveX controls.
So the only way to use your win32 application into a gadget is convert the application to a Activex Control.
You can read these articles
