Is it possible to create an application with a transparent background on the root task such that you can see the task running beneath it when it is part of a separate stack? Alternatively, is it possible to run an application so the window of the root task is only a portion of the screen instead of the whole screen? I understand how the...
Hello I am trying to build a framework of IAction objects that will execute in a sequence. Each IAction implementation will execute its processAction() method as it was implemented for. This method returns a IAction, which in most cases is itself, but in some cases may be a pointer to another IAction in the List. The IActionIterator...

A couple of Relational DB tables are managed by a single object cache that resides in a process. When the cache is committed the tables are updated. The DB relational tables are updated by regular SQL queries and not anything more fancier like hibernate. Eventually, other processes got into the business of modifying this object without ...

I am trying to remove the drag bar across the top of the JFrame. I would like to keep the minimize maximize and close options that appear on this bar available. What I was thinking was to remove the bar (and icons). Then add the icons as embedded images, that implement the JFrame actionlistener. It would also be necessary for this to wor...
When writing a custom string class that stores UTF-8 internally (to save memory) rather than UTF-16 from scratch is it feasible to some extent cache the relationship between byte offset and character offset to increase performance when applications use the class with random access? Does Perl do this kind of caching of character offset t...

I tried to type char literals for accentuated vowels in Java, but the compilers says something like: unclosed character literal This is what I'm trying to do: char [] a = {'à', 'á', 'â', 'ä' }; I've tried using Unicode '\u00E0' but for some reason they don't match with my code: for( char c : string.toCharArray() ) { if( c == ...

I'm writing a library that needs to have some code if a particular library is included. Since this code is scattered all around the project, it would be nice if users didn't have to comment/uncomment everything themselves. In C, this would be easy enough with a #define in a header, and then code blocks surrounded with #ifdefs. Of cours...
