  • C++ Logger-Should I use an ordinary xml parser?

    - by Jonathon
    I'm working on a logging system for my 2D engine, and I'm confused on how I should go about creating/editing the file, and how I should output that file. I've learned that XML is more of a data carrier rather than a data displayer like HTML is. I've read that I can use XML to HTML converters. One method I've thought about is writing characters to a file in HTML. Clarity on these matters is what I ask of you, stack overflow.

  • How to implement a timer callback that executes in the same execution context

    - by Waldorf
    Some programming environments like C++ builder have timer components with a callback function which executes in the same execution contexts as where the timer object is created. I was wondering how to do something similar in plain c++ with threading. Or are there any other ways to have a callback which is periodically called to perform some task and runs in the same execution context as the calling thread?

  • find: What's up with basename and dirname?

    - by temp2290
    I'm using find for a task and I noticed that when I do something like this: find `pwd` -name "file.ext" -exec echo $(dirname {}) \; it will give you dots only for each match. When you s/dirname/basename in that command you get the full pathnames. Am I screwing something up here or is this expected behavior? I'm used to basename giving you the name of the file (in this case "file.ext") and dirname giving you the rest of the path.

  • As a programmer, how much time do you spend churning?

    - by Chinnery
    I recently went through a period of frustration, "churning" as I tried to set up my environment to work effectively on a task. By the time I broke through and started to make actual progress, I felt tired and kind of angry. (I'll admit: in this case, it took me several days of banging my head and ultimately starting from scratch to finally get around the problems.) This experience made me wonder: When a roadblock happens to other programmers, how long do they churn before finally becoming productive and beginning what feels like actual work?

  • How to test if table was updated in Zend Framework?

    - by AD
    When user opens a form to modify a record, but instead of changing information, he just clicks the Update button. Which causes the update() function to return 0.

  • Could I ever want to access the address zero?

    - by Joel
    The constant 0 is used as the null pointer in C and C++. But as in http://stackoverflow.com/questions/2389251/pointer-to-a-specific-fixed-address there seems to be some possible use of assigning fixed addresses. Is there ever any conceivable need, in any system, for whatever low level task, for accessing the address 0? If there is, how is that solved with 0 being the null pointer and all? If not, what makes it certain that there is not such a need?

Is there nay better implementation for this task?

  • Extract a portion of a Qt .ui file into its own .ui file

    - by Grant Limberg
    We have a designer creating a user interface for an application. The main window has several QStackedWidgets used for in place panel switching. What I'd like to be able to do is extract each individual panel that makes up each page of the QStackedWidget into it its own .ui file. Is there an easy way to accomplish this from within Qt Designer, or are there any other tools to help accomplish this task short of redesigning all of the panels in their own .ui files?
