This seems like a lot of work; to check for null each time an object is used.
I have been advised that it is a good idea to check for null pointers so you don't have to spend time looking for where segmentation faults occur.
Just wondering what the community here thinks?
Which way is preferred in expressions like this:
int? Id
{
get
{
int i;
return Int32.TryParse(Request["id"], out i) ? i : (int?)null;
}
}
is it better to cast on null or create a new Nullable<T> ?
Being a Windows convert, I am looking for Task Manager equivalent for OS X.
Please do not recommend Activity Monitor, since it misses two important features of Task Manager:
per process disk i/o (read, write, other)
simple process description (like what is this 'mds' process? where does it live?)
Any suggestions?
Is there a good task manager or utility for Windows XP that gives deep visibility into the processes and threads running on the current system? I know that the task manager on my Windows 7 PC has a lot more information than does Windows XP. Any ideas?

Hi, quick question. Is there any way to (easily) retrieve the parent layout of a widget in Qt?
PS: QObject::parent() won't work, for logical reasons.

I'm positive the widget has a parent layout, because I added it to a layout earlier in the code. Now, I have many other layouts in the window and while it is possible for me to keep track…
