The GIMP 2.2 is now out. Download for Windows: http://gimp-win.sf.net/ . The GIMP is a tool for working with and manipulating images and is open source. Not the most intuitive tool but very powerful, and is extended via plugins . Since the GIF patent expired you can generate GIF images (not available in version 2.0 and earlier). The file open/save dialog is a lot better in this version than the last version (2.0) and contains an image preview. Works on many platforms. A good free tool for working with graphics. If you already have Photoshop or another professional package, then this may not offer any more over it.

Smart Navigation (i.e. maintaining scroll position) only works in Internet Explorer. Luckily there is a way to get it to work in other browsers as well. Coding Horror: The Antidote to ASP.NET Smart Navigation, Part Deux

The web developer extension for Firefox has been updated to version 0.9.1. It has a few bug fixes over 0.9.

CodeProject Article: Mastering ASP.NET DataBinding The goal of this tutorial is to shed light on some of the more common and frequently asked questions about the capabilities of databinding.

First extension I have seen for NVU: htmlHeader Toolbar for N|Vu 0.6 .

When using SUM on a field ('bitcolumn') with the data type 'bit', you may not get the expected result - i.e. you would expect it to return the count of all the rows that have this field set to true (1). SELECT SUM(bitcolumn) However, it returns an error: The sum or average aggregate operation cannot take a bit data type as an argument . You can however, use CAST to convert 'bit' to 'int', and perform SUM on the result. SELECT SUM(CAST(bitcolumn As int)) This can however result in NULL returned as a value, when you want 0 instead. To always get a number as the result, you can also use COUNT combined with CAST and NULLIF. The key is that COUNT does not include any rows with NULL set on the field you are querying. CAST converts to 'int' and NULLIF converts the 0's to NULL's. COUNT therefor only includes the row count you want (where the field value is 1). SELECT COUNT(CAST(NULLIF (bitcolumn, 0) AS int))

OdeToCode article: Digging Into Data Binding Expressions . 'This article will demonstrate some techniques beyond simple DataBinder.Eval calls in ASP.NET data binding expressions.' . Includes usage of a method written in your code-behind, or casting (converting from one type to another, C# only).

Generic Url Creator (GUC) is a Firefox extension that creates a URL from the text you select (i.e. use to lookup definitions, or perform a search). You can edit the list via the use of regular expressions.

A useful Firefox extension that allows you to save web pages (or snippets from a web page). You can also search the snippets as well. ScrapBook Homepage . Good for when you find some code on a web site and want to quickly save it.

How to make a theme for Firefox. cheeaunblog - First steps in theme design . The author of this post created the Phoenity Theme .

CNET has a feature where you can vote for which is the best browser: Sunday Smackdown: Mozilla Firefox 1.0 vs. Internet Explorer 6 . Obviously you vote for Firefox (it already has 90% of the votes)

A guide to tweaking the various features in Firefox: Firefox Tweak Guide . Written before Firefox 1.0 came out, but still relevant. Edit: Another way of speeding up Firefox would be to try one of Moox's custom builds . There is also a list of freeware on that site as well.

Daniel Glazman (NVU developer) has written a post on what he thinks of the current state of CSS and what should happen in the future: Calling for a new CSS revolution . An interesting read. What would the web be like now if Microsoft continued to work on Internet Explorer? I'm sure it would have been a lot better (less hacks for CSS in IE, better looking sites). Instead, Longhorn/Smart Clients is part of their future strategy and could go any way (new hardware and OS would be required, but you would be tied to Windows and would therefor be more expensive). Richer applications, but to the detriment of competition (i.e. Novell/IBM/Sun - who are investing in Linux and thin-clients) and the environment (old PC's going into landfills).

MSDN Article on creating validation controls dynamically via an XML file.

A few useful utilities from zeraha.org : nPad - source viewer/editor with syntax highlighting NetGraph - real-time network monitor CodeBank - code snippet database with syntax highlighting ImageScaler - quality image scaling/rotation XMLPad - XML Editor IconInjector - replace icon in exe/dll file (via command line) MovieBank - movie database MemBoost - defrag memory in Win 95/98 nSMS - send SMS via email (requires email-to-SMS gateway)

Google has a beta feature that offers suggestions as you type: http://www.google.com/webhp?complete=1 . Works the same way as typing a name into the To box when composing an email in GMail. What is good about it is that it does it so quickly (considering the amount of data they hold) and lists how many matches to each suggestion. The good thing with Google is that new features they add are browser friendly (i.e. work in Firefox, Safari, Mozilla and Opera - so don't just test against Internet Explorer). It looks like they probably use web services extensively via JavaScript and XMLHttpRequest (Mozilla/Firefox/Opera/Safari) or Microsoft.XMLHTTP / Msxml2.XMLHTTP (Internet Explorer).

Code Project has a 4-part series on creating a web page class library that can be implemented in your web application: BasePage, MenuPage and VerticalMenuPage - A set of common, reusable page classes for ASP.NET applications. BasePage (continued) - Detecting changes in data controls in ASP.NET web forms. EmailPage - An ASP.NET page class that has the ability to e-mail its rendered content. PageUtils - A utility class containing some useful features for ASP.NET applications.

There is a free eBook (i.e. PDF document) available on SharpDevelop. While SharpDevelop does not do ASP.NET, it has a decent code editor with syntax highlighting and code-completion. So useful for building libraries (i.e. a data access layer or common function library) for use within a web application. It also does not have version control (had CVS support in the past, but that was dropped). With enough demand (and hopefully more developers), SharpDevelop may get ASP.NET and source control in the future - which are essential if it really wants to compete with Visual Studio. At the moment the only decent tool for ASP.NET development is Visual Studio (which is sometimes out of people's budget, especially if they work for non-profit or budget sensitive organisations) - and that likes to reformat your code. Dreamweaver does ASP.NET - but no support for code-behind or code-completion (except for tags - even then, only the ones part of ASP.NET, not custom ones). More information/down...

There is a tool available for reporting sites that have issues with Firefox (and other Mozilla based browsers) - telling user to use Internet Explorer, blocking access, or with rendering/dhtml problems. There is a web-based form and an extension available to do this. More information/screenshots: gemal.dk - New Reporter Tool .

MSDN Article - Developing a Validator Control . There are also alternatives to ASP.NET's built in validation controls that function the same but work in other browsers - DOM-Compliant Validator Controls (also available on Glavs Homepage at ASPAlliance.com ) The site seems to have a CSS bug that makes it display incorrectly in Firefox/Mozilla. There is a feedback form for contacting the WebMaster (fix is to remove the height: 33px; line in the div.abstract class in the stylesheet aspalliance.css ). The validation controls in the next version of ASP.NET should work in browsers other than IE .

When searching for data in a column, you may want to perform an OR AND or exact term on a user supplied string. When you use LIKE, the column needs to contain the whole text string, which is not always what you want. One way round this is to use a stored procedure as outline by Jeff Smith (Dr. Cross Join) a member of SQLTeam.com - Search Logic For Multiple Search Terms

NVU 0.6, the free WYSIWYG html editor is now available for download. Still a long way to go before it is near Dreamweaver in terms of functionality. Has a few bugs as well (reformats code, does not work well with server side (ASP,PHP) code, adds DOCTYPE declaration (which you can't change) even when you don't want one (i.e. when editing an include file, or a template file used within a CMS), no XHTML support). Hopefully 1.0 will be a lot better (but will probably be a lot better by 2.0) Site manager has improved, but could be better (i.e. context-menu, handling of other file types - cannot open ASP/ASP.NET files with it, no ability to add association (or use built in Windows associations). Perhaps it could be better if there were more working on the project ( Daniel Glazman seems to be the only one (that I know of) actively working on it)? Download page Mailing List Forum
