Why is a font in .NET of size 8 displayed as 8.25? <p>When you select, for example, a Size of 8 in a Font Dialog for Microsoft Sans Serif, it returns a font that .NET displays as having a size 8.25? </p>

excel: charting with unknown number of data <p>Let's (for discussion purposes) say that I have x and y data in 2 columns. They're some measured data which, several times a day, a few of them are added (usually 4 times a day).
Now, I wish to plot y=f(x) (linear scale), but the problem is since data is constantly added t... | <p>You can do this without any VBA. Jon Peltier has an example by Debra Dalgleish on his website:</p>

Recommendations for AJAH Library <p>I have a classic ASP application</p>
<p>I would like to add some AJAX-style partial page updates to avoid server roundtrip. For example, list of rows displayed, option to add another in-situ, save it, and table redisplayed / add another.</p>
<p>I don't think I need all the other b... | <p>AJAH? There is to my knowledge no such thing as AJAH. Does the H stand for HTML instead of XML? If so, let me disabuse you of the notion that AJAX entails XML. That may have been its inception but that is not the case (now at least). In the moern vernacular Ajax has come to mean pages making Javascript calls ba... |
mysql keyword search <p>I have a table with names of movies, and I want to be able to search for a movie in that table. But I want to be able to search for part of the title, and still return a result. For example, if there is a record with the name "The quantum of solace", then I want to be able to do a search for "qu... | <p>Use a <a href="http://dev.mysql.com/doc/refman/5.1/en/fulltext-boolean.html" rel="nofollow">MySQL Full Text Search</a> in boolean mode.
If you do this when you search for '007: quantum solace' as it contains at least one matching result in the column it will be displayed, you can then order by relevancy.</p>

Visually edit C# imagemap control? <p>I just discovered the imagemap control in Visual Studio 2008.
I'm familiar with the imagemap concept from HTML, I'm just used to having editors that allow you to select areas visually, like drawing a hotspot on the image itself, and the software generates the HTML itself.
But I can... | <p>No, AFAIK there is no designer support for hotspots - I use a piece of paper.</p>
<p>Concerning the code, you'll have to set HotSpotMode="PostBack" PostBackValue="HS1" for each hotspot and use a switch statement in ImageMap1_Click to react to the different Postback values.</p>
