If you use a static instance field that you initialize in your cpp file, you can get multiple instances (and even worse behavior) if the initialization of some static/global tries to get an instance of your singleton. This is because the order of static initialization across compilation units is undefined. |
I had to add the registry file AND re-run "regsvr32 actxprxy.dll" This was a really odd and painful error. It only seemed to come into existence after installing VS SP1 but I really don't see why that would have happened. |
Unless you do a major rewrite of code, it is not possible to run Postgres "embedded". Either run it as a separate process or use something else. SQLite is an excellent choice. But there are others.

@a7an: Ah, I didn't notice the Icon property before. That's a good start.

The thing that makes a tag cloud really useful (at least a well implemented tag cloud IMO) is the ability to drill into a topic deeper and deeper.

If you do array_filter(explode('/', '1/2//3/')) you'll get all values that resolve to "false" filtered out (see http://uk.php.net/manual/en/function.array-filter.php). |
Yes, we had the same issue, and we decided not to upgrade either. We haven't seen any problems, so you're OK ignoring the warnings. |
The Hotspot JIT can now produce code *faster* than C++. The reason is run-time empirical optimization.
For example, it can see that a certain loop takes the "false" branch 99% of the time and reorder the machine code instructions accordingly.

System.Web.Mail is not a full .NET native implementation of the SMTP protocol. Instead, it uses the pre-existing COM functionality in CDONTS. System.Net.Mail, in contrast, is a fully managed implementation of an SMTP client.

Part of the problem is that the Java/C# language and its libraries are based on English words like `if` and `toString()`. I personally would not like to switch between non-English language and English while reading code.

You shouldn't, and it's very unlikely you need to. If you need to access the property, just use the public property (e.g. this.Age). There's nothing special about the private field backing the public property, using it in preference to the property is just superstition.

Assuming the characters are present in a text field:
update TABLE set COLUMN=REPLACE(convert(varchar(5000), COLUMN), 'searchstring', 'replacestring')
(note that this will only work on a text field with no more than 5000 characters, for larger text fields increase the number in the query).

Consider also that you can often replace both with derived tables which may be faster as well. As with all performance tuning, though, only actual tests against your actual data can tell you the best approach for your particular query. |
