I have a ColdFusion function "foo" which takes three args, and the second two are optional: <cffunction name="foo" access="public" returntype="any"> <cfargument name="arg1" type="any" required="true" /> <cfargument name="arg2" type="any" required="false" default="arg2" /> <cfargument name="arg3" type="any" required="false" d...
Hello Hello, Buried in mySQL syntax and query structure problems once more. I'm currently doing this query fine:- SELECT DATE_FORMAT(`when`, '%e/%c/%Y')date , COUNT(`ip`) AddressCount FROM `metrics` WHERE `projID` = '$projID' GROUP BY DATE(`when`) This works fine to find the specific number of ip address's hit. However, what...
Just studying the C style of Jon Bentley's Programming Pearls and was wondering if someone could please explain to me the following two pieces of C syntax: A for with no init condition (see line 2 in wordncmp in the file above): for ( ; *p == *q; p++, q++) and the semantic difference between char *word[800000]...

array<int> ^ints = gcnew array<int>{ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 }; for each(int i in ints) if(i % 2 == 0) Debug::WriteLine("Even\n"); else Debug::WriteLine("Odd\n"); Why does the above fail to compile? It works fine if I use a for(int i; ...) or if I enclose the if-else within braces. I know that the manual cl...

Sorry for asking such a newbie question, I know it makes a few of you here angry. But I think learning the syntax is the hardest part so don't flame me too badly.

is it possible to do something like the following in ASP.NET: <tr<%= index++ % 2 == 0 ? " class=\"alt-row\"" : ""; %>> in other words, is there a way to escape the angle brackets for the inline code block or something?

This is ok: $foo++ if $condition; And this is ok: $foo++ for (1..10); But this isn't: $foo++ if $condition for (1..10); I find the latter quite readable if things aren't complicated, and it fits on one line! Is there a way to do this or should I move on with my life? ...

I have the following query:- SELECT `country`, COUNT(`ip`) AS `cViews` FROM `metrics` WHERE `projID` = 'projID' AND `country` != 'XX' AND...
In struts I notice there are two different ways to access variables. I am curious what the difference is and when to properly use each one. For example, suppose we set the variable height like so: <s:set var="height">300px</s:set> Now I can use it two ways: <div style="height: ${height}"> </div> ..or.. <div style="height: <...
I'm dealing with an annoying database where one field contains what really should be stored two separate fields. So the column is stored something like "The first string~@~The second string", where "~@~" is the delimiter. (Again, I didn't design this, I'm just trying to fix it.) I want a query to move this into two columns, that would...
Dear all. Unfortunately I haven't coded Java for about five years and I absolutely can not remember how or why the following code is working. I stumbled across a similar example and broke it down to this. The emphasis is on the part below the comment: I don't get the constructor notation followed by the block in double brackets. And ...
