Ah, got it. Right after I append the HTML to the DOM I run this on all the inputs I’d like to have a datepicker pop up with. Datepicker adds a class to elements it has been attached to, so we can filter out existing inputs and only apply it to new ones. $(‘.date’).not(‘.hasDatePicker’).datepicker(); I … Read more
There are several issues: Class names (and IDs) are not allowed to start with a digit. You have to pass a class to getElementsByClassName(). You have to iterate of the result set. Example (untested): <script type=”text/javascript”> function hideTd(className){ var elements = document.getElementsByClassName(className); for(var i = 0, length = elements.length; i < length; i++) { if( … Read more
It’s much easier to do the following: In log4j.xml define variable as ${variable}: <appender name=”FILE” class=”org.apache.log4j.FileAppender”> <param name=”File” value=”${logfilename}.log” /> <layout class=”org.apache.log4j.PatternLayout”> <param name=”ConversionPattern” value=”%d::[%t]::%-5p::%c::%x – %m%n” /> </layout> </appender> Then make sure you set the system property when you start your JVM such as: java -Dlogfilename=my_fancy_filename example.Application That will create a dynamic log file … Read more
A matrix is actually can be represented as an array of arrays. int rows = …, cols = …; int** matrix = new int*[rows]; for (int i = 0; i < rows; ++i) matrix[i] = new int[cols]; Of course, to delete the matrix, you should do the following: for (int i = 0; i < … Read more
What you are proposing is not new. Plenty of people have tried it… most have found that they chase “infinite” flexibility and instead end up with much, much less than that. It’s the “roach motel” of database designs — data goes in, but it’s almost impossible to get it out. Try and conceptualize writing the … Read more
Variable Length Arrays(VLA) are not allowed in C++ as per the C++ standard. Many compilers including gcc support them as a compiler extension, but it is important to note that any code that uses such an extension is non portable. C++ provides std::vector for implementing a similar functionality as VLA. There was a proposal to … Read more
Use a Dictionary<string, Variable>. e.g. var vartable = new Dictionary<string, Variable>(); vartable[strLine] = new Variable(input);
For anyone else trying to do something like this: don’t. Instead, think of the flow of information and understand that there is a better way to do it. The input control(s) do not need to be dynamically created. They can be static, and upon filling out and submitting on one, that information has to go … Read more
