Resolved: How to align 3 divs (left/center/right) inside another div?
posted by admin on July 18, 2016


Container div is 100% wide (no set width), and center div should remain in center after resizing the container.

So I set:

#center{margin:0 auto;width:100px;}

Wiki: Joining Three or More Tables SYNTAXwiki
posted by admin on June 18, 2016
Although each join specification joins only two tables, FROM clauses can contain multiple join specifications. This allows many tables to be joined for a single query.

The ProductVendor table of the AdventureWorks2008R2 database offers a good example of a situation in which joining more than two tables is helpful. The following Transact-SQL query finds the names of all products of a particular subcategory and the names of their vendors:

SELECT p.Name, v.Name
FROM Production.Product p
JOIN Purchasing.ProductVendor pv
ON p.ProductID = pv.ProductID
JOIN Purchasing.Vendor v
ON pv.BusinessEntityID = v.BusinessEntityID
WHERE ProductSubcategoryID = 15
ORDER BY v.Name;

Resolved: JPG vs. JPEG image formats
posted by admin on June 18, 2016
I often use JPEG images, and I have noticed that there are two very similar file extensions: .jpg, which my mobile's camera and the Preview application use, and .jpeg, with which Image Capture saves the images from scanning with my Canon MX455 printer. LaTeX doesn't seem to distinguish, as I gave it a .jpeg with the extension changed to .jpg and the result seems to be the same as if it had been a .jpg right from the start. I have wondered what the difference between the two is. I have come across this question, and will certainly read through it, though at the moment I'm slightly out of time. However, from what I saw giving it a quick look, it seems not to distinguish the two extensions. In fact, it seems the file type's name is JPEG and the file extension is .jpg:

JPEG (or JPG, for the file extension; Joint Photographic Experts Group)

(excerpted from the first answer there). So is there any big difference between the two extensions? And if so, what is it?Read more
Resolved: MySQL Like string in multiple value by one script
posted by admin on June 18, 2016
I always thought that you could use OR in a LIKE statment to query things in MySQL. So, if I wanted to compare multiple fields in a row to 1 keyword or term:

SELECT * FROM MyTable WHERE Column1 OR Column2 LIKE '%keyword%';

and if I had an array of words to compare:

SELECT * FROM MyTable WHERE Column1 OR Column2 LIKE '%keyword1%'
AND Column1 OR Column2 LIKE '%keyword2%';

I don't believe that syntax is correct, however. Is there an efficient method of writing this aside from something like:

SELECT * FROM MyTable WHERE Column1 LIKE '%keyword1%' OR Column2 LIKE
'%keyword1%' AND Column1 LIKE '%keyword2%' OR Column2 LIKE '%keyword2%';

Resolved: How to clear browser cache when re-uploading image with same filename, in php?
posted by admin on June 18, 2016
I have a listing of items, that also contains an image thumbnail. Sometimes I need to change the thumbnail image, but keep the filename the same. Is there a way to force the browser to download the newly uploaded image, instead of grabbing one from the browser cache?

This is very pertinent when people update their avatars, which causes confusion for some users, who keep seeing their old avatar, until they clear the browser cache, or restart the browser.Read more
