  • Define global textbox (or other control) width in WPF

    - by John B
    I'd like to be able to maintain the width of controls globally throughout my WPF application. Previously in winforms world I'd override onload in a base form and iterate through all controls and containers and determine the type of controls and set the dimensions accordingly. I guess I could do the same in WPF but is there any better way to do this?

  • Would the instance reference parameters passed into the static methods get garbage collected?

    - by 123Developer
    I know that the static objects in .Net managed world are loaded in Loader Heap which is never going to be garbage collected. What happens to the instance reference parameters passed to a static methods. Are they get garbage collected once the static function executed completely Or they are going to live forever as those instance reference variables are once passed to static method? I am really confused this evening; Please guide me. Thanks and regards 123Developer.

  • Detected when everything has finished downloading

    - by oshirowanen
    Using only HTML, CSS, and Javascript, has the web development world got to a stage where it is possible to display a loading message on the screen until absolutely everything has downloaded before the web page is displayed on the screen? For example, display "loading", until all html, css, javascript, images etc etc have downloaded and can be displayed without the user seeing bits of the website still appearing after the load message has gone?

  • Does anybody actually use the permissions policy controls in tomcat?

    - by stu
    While I can appreciate the point of the fine granularity in which you can enable security for every single little thing for each individual application in tomcat, in reality, it's an insane pain in the ass. Every single file, socket, everything for every single application. Sure if you're writing a "hello world" application, it's not too much to ask, but an enterprise sized application? That's insane. Does anybody actually use it, or does everybody just say "*" for everything?

  • Javascript text insertion in textbox.

    - by Guru
    Hello there, I've got a textbox(id="tb1") and a button(id="btn1"). I want that whenever I click on btn1 a text "hello world" must be inserted in the tb1 at the current position of cursor in text-box. Please provide me a cross browser solution for this. Since I'm frosted from some heavy extra ordinary links so it'd be better to post a function considering the current scenario. Thanks, Guru

  • Is it possible to use CSS to align these divs/spans in a table-like manner? (While still retaining continuity)

    - by Justin L.
    I have <div class='line'> <div class='chord_line'> <span class='chord_block'></span> <span class='chord_block'>E</span> <span class='chord_block'>B</span> <span class='chord_block'>C#m</span> <span class='chord_block'>A</span> </div> <div class='lyric_line'> <span class='lyric_block'></span> <span class='lyric_block'>Just a</span> <span class='lyric_block'>small-town girl</span> <span class='lyric_block'>living in a</span> <span class='lyric_block'>lonely world</span> </div> </div> (Excuse me for not being too familiar with proper css conventions for when to use div/spans) I want to be able to display them so that each chord_block span and lyric_block span is aligned vertically, as if they were left-aligned and on the same row of a table. For example: E B C#m A Just a small-town girl living in a lonely world (There will often be cases where an empty chord block is matched up to non-empty lyric block, and vice-versa.) I'm completely new to using CSS to align things, and have had no real understanding/experience of CSS aside from changing background colors and link styles. Is this possible in CSS? If not, how could the div/class nesting structure be revised to make this possible? I could change the spans to divs if necessary. Some things I cannot use: I can't change the structure to group things by a chord_and_lyric_block div (and have their width stretch to the length of the lyric, and stack them horizontally), because I couldn't really copy/select the lyrical lines continuously in their entirety, which is extremely critical. I'm trying to avoid a table-like solution, because this data is not tabular at all. The chord line and the lyric line are meant to be read as one continuous line, not a set of cells. Also, apart from the design philosophy reasons, I think it might have the same problems as the previous thing bullet point. If this is possible, what div/span attributes should I be using? Can you provide sample css? If this is not possible, can it be done with javascript? EDIT: I'm sorry I wasn't clear at the start, but I would like a solution that allows both the chord line and the lyric line to be "selectable" and continuous.

  • a good resource or book for architecting object-oriented software

    - by Ygam
    I have looked at a couple of books and all I have looked at were just discussing the technicalities of OOP. By technicalities I mean, here's a concept, here's some code, now get working. I have yet to see a book that discusses the architectural process, what are the ways of doing this, why doing this is bad, how to actually incorporate design patterns in a real-world project, etc. Can you recommend a good resource or book? I am mainly programming with PHP but a language-agnostic book/resource would do :)

  • If i write in assembly or machine language, will the program work on any computer with a compatible processor?

    - by user663425
    Basically, i'm wanting to know if i can use either machine or assembly language to write a program that will work on any computer with an x86 processor, despite differences in operating systems. For example, you run a program and no matter what computer it's on, it'll display "Hello, World!" I know it's a little crazy to want to know either of these to languages, but i figure it's an incredible thing to learn, so why not?

  • Is it okay to use zoom:1 in my css classes?

    - by Spines
    Whenever I find IE is displaying my website weird (different from chrome and firefox), I try putting a zoom:1 in the css class for the part that is being displayed weird. A lot of the time this fixes the problem and makes it look consistent with the other browsers. Is it a problem to use zoom:1? I know my CSS won't validate, but are there any real world problems that can arise if I rely too much on using zoom:1?

Any ideas what to change here?
