  • TreeNode Selection Problems in C#

    - by user455046
    Whenever I click outside the tree nodes text, on the control part, it tigers a node click event- but doesn't highlight the node. I am unsure why this is happening. I want the node to be selected on a click- when you click the nodes text- not the whitespace- I only assume that the nodes width reaches across the whole Treenode? I have the Treeview on dock.fill mode if that has something to do with it- I tried everything but can't get it to behave correctly. Maybe someone will know what's going on. Update: if (e.Location.IsEmpty) { Seems to work better- but still selects the node in the blank place where there is no text- Obviously the node width extends across the whole treeview it seems? Is there a better way to accomplish what I want? Or is that the best way? UPDATE: Previous idea isn't working- sigh- I thought it did it but it didn't. New Problem : I think part of the problem is related to the focus now when I switch from treeview.

  • How to get JDK 1.5 on Mac OSX

    - by Eric
    I've got to write some code for a legacy application that is still running JDK 1.5. Unfortunately, it looks like OSX doesn't actually have a 1.5 JDK installed, it just links to 1.6: /System/Library/Frameworks/JavaVM.framework/Versions $ ls -l lrwxr-xr-x 1 root wheel 5 Apr 26 11:53 1.3 -> 1.3.1 drwxr-xr-x 3 root wheel 102 Feb 11 15:33 1.3.1 lrwxr-xr-x 1 root wheel 10 Apr 26 11:53 1.4 -> CurrentJDK lrwxr-xr-x 1 root wheel 10 Apr 26 11:53 1.4.2 -> CurrentJDK lrwxr-xr-x 1 root wheel 10 Apr 26 11:53 1.5 -> CurrentJDK lrwxr-xr-x 1 root wheel 10 Apr 26 11:53 1.5.0 -> CurrentJDK lrwxr-xr-x 1 root wheel 5 Apr 26 11:53 1.6 -> 1.6.0 drwxr-xr-x 7 root wheel 238 Apr 26 11:53 1.6.0 drwxr-xr-x 8 root wheel 272 Apr 26 11:53 A lrwxr-xr-x 1 root wheel 1 Apr 26 11:53 Current -> A lrwxr-xr-x 1 root wheel 3 Apr 26 11:53 CurrentJDK -> 1.6 It sounds like from http://developer.apple.com/java/faq/ that Java is part of the OS update...I'm on OSX-10.6.3. Anybody know of a way to get an actual 1.5 JDK installed on this OS version? Or do I need to try and find an old version of OSX before I can do this work?

  • WPF: Is ListBox or Panel responsible for mouse wheel navigation?

    - by HDW
    I have a custom ListBox which uses a custom Panel as ItemsHost. I want to have control over mouse wheel input, so that turning the wheel changes the single selected item. I believe that the best method to do so is to handle the OnPreviewMouseWheel event (although this is only have what I want since it doesn't provide horizontal wheel data). Now the big question: Is there a best practice where to handle OnPreviewMouseWheel? In ListBox (which by default doesn't have a clue about the arrangement of the Panel's child elements) or in Panel (which by default doesn't have a clue about the "IsSelected" property of it's child elements)?

  • [JS] getSelection on DIV contentEditable

    - by cactoos
    Hi all ! I am trying to achieve project and i must do a WYSIWYG editor in JavaScript. I can't use an existing editor because I need use my plugins (for example a colorPicker or imagePicker).. For this time I have this HTML : <div class="K_editor" id="idExample"> <div class="K_links"> <div class="K_editor_link K_editor_linkBold">B</div> <div class="K_editor_link K_editor_linkItalic">I</div> <div class="K_editor_link K_editor_linkUnderline">U</div> </div> <iframe width="696" height="212" frameborder="0" src="js/myEditor_iFrame.php"> <html> <head/> <body> <div id="contentIframe" contenteditable="true"> This is a test code, with <strong>bold</strong> text and <em>italic</em> text. </div> </body> </html> </iframe> <input type="submit"/> </div> On event click on ".K_editor_link", a function is open with arguments : - tagStart (exemple '', or '') - tagEnd (exemple '', or '') - id (here 'idExample') I know get a Selection on Textarea but "setSelectionRange()", ".selectionStart" and ".selectionEnd" are only for textbox (XUL), input (XHTML) or textarea (XHTML). Why can I do for do that ?? I'm realy block.. Thank all ! CactO_o's

  • Javascript: click and dblclick deliver different parentNodes on same html. Why?

    - by user1658206
    currently I work on an very small wysiwyg editor based on jquery. I dont care about IE oder Chrome, just Firefox. My problem is to find if the selection is in a link for to get the value of the href attribute if is set. With click the node of the link is found, with double click always the body. It is in designMode. My event-handler for click and dblclick. The vars current_selection, current_node, iframe and container are global. selection_handler:function() { current_selection = iframe.getSelection(); current_node = current_selection.anchorNode; if(current_node.nodeName == "#text") { current_node = current_node.parentNode; } $('#log').text(current_node.nodeName); }, The log shows mit for example 'body', when I click in unformated text. When I add a link with execCommand('createLink',...) the log shows 'A'. That works. When I mark the linked word with 2 click from start to end, the log shows 'A'. But with double click I always get 'body'. So I can't get the href attribute. The handler is defined in the init: init:function(options) { ... iframe = $('#wysiwyg-'+container.attr('id'))[0].contentWindow; iframe.addEventListener('dblclick',methods.selection_handler,false); iframe.addEventListener('click',methods.selection_handler,false); ... } Has somebody an idea what is wrong?

  • Benefits of migrating my work to a new web development framework?

    - by John
    When I first started programming with PHP, I was ignorant of other php frameworks (like code igniter, cake php, etc...). So I fell into the trap of re-inventing wheels, which had the benefit of being "fun" and "educational". Overtime, I discovered other open source products that I found useful, like smarty templating engine, jquery library, tcpdf library, fdf etc...so I started bundling these technologies along with things I've built over the years into a LAMP development framework to make life easier for myself. This pass year, I've been having fun developing on the code igniter framework. It does many of the things I do in my framework. Coding in CI feels natural because the MVC and ORM feels similar to the MVC and ORM of my framework. So now I'm contemplating migrating a lot of the plugins in my framework over to CI. The pros and cons I can think of for such a project are: Pros: benefit from the vast community of CI developers lots of other developers will be familiar with it better documentation Cons: I've built a lot of useful plugins against my own framework, and it will take a lot of time to move even just the essential ones at the moment, I still, work faster against my own framework than CI, just because I'm more familiar with it even if I did migrate to CI, there will always be newer and better frameworks in the near future, and i'll be contemplating this scenario again So my question is the following: perhaps I should leave my old framework as is, and for each new project I receive, I make a decision on whether the requirements are best served by developing with CI or my own framework. Is this the right approach?

  • Should I write my own forum software?

    - by acidzombie24
    I have already built a site from scratch. It has banning, PM, comments, etc. The PMs and comments are done using markdown (like SO). There are pros and cons for writing my own or using another software. But some cons keeping me from using another forum software is Multiple Logins: One for the site, one for separate forums. Need to Customization code: I'll need to change the toolbar in the forum software so I can access pages on the regular site. Look consistency: It may look drastically different from my site even after applying lots of css changes. Banning and User consistency. Users may be ban on site or on forums but not the other. users may select a different or multiple usernames on the forum instead of being forced to use the same username on both site and forum. Should I write my own forum code or should I use something already written? What are some reasons for or against writing my own and using forum software?

  • How to make mouse wheel to scroll control under mouse cursor?

    - by skevar7
    Currently, mouse wheel scrolls the control that has keyboard focus. That's not good when window has several scrollable controls, because I have to click control first and then scroll. And the same again when trying to scoll another control. Especially bad, when that control has some action associated with click (like MSDN's article list - it opens new article on click). So, is there any tool to fix mouse scroll behavior?

  • GNU Screen: Remap mouse-wheel to active scroll back.

    - by User1
    I am using Screen with MinTTY at a bash prompt. Sometimes I want to activate scrollback and copy some stuff that was on the output. My first instinct is to scroll with the mouse, but all that happens is old bash commands start showing up (like when I press the up arrow). Is there a way to re-map the mouse wheel to: Go into scrollback mode, or If already in scrollback mode, start moving up in the scrollback window

  • tmux -- any way to enable scrolling, but not selection?

    - by gatoatigrado
    I like that when mode-mouse is on in tmux, I can scroll through the buffer, but I don't like that I can't copy stuff to my OS clipboard by selecting it (as when tmux is disabled). Question: Is there any way to enable mouse scrolling, but not selection? I'm using KDE's konsole, if it matters. I've tried setting, set -g mouse-select-pane off set -g mouse-select-window off but no luck -- the only difference seems to be whether mode-mouse is on (tmux captures scrolling and selection) or off (tmux captures neither scrolling nor selection).

  • WPF MVVM Picklist Example

    - by Tim
    Hi, I am looking for a way of easily maintaining a list of Users belonging to a particular Group. I have thought about using a Picklist, where I have 2 listboxs, the first contains a list of Users the second a list of Users belonging to the Group. There will be buttons to allow the adding and removing of selected Users from the Group. As users are added they move from the left listbox to the right, as they are removed they are move from the right to the list. This is pretty common situation. Do you know of any examples of doing this in WPF using the MVVM pattern? I am having difficulty understand how the binding may work to my View Model and Business Entities. Especially persisting the data back to the database. I am using stored procedure calls to do the CRUD logic, so I need to keep a list of which Users had been removed so I can delete them. Is this the best way to perform this functionality or is there a better way. I simply want to pick from a list (the list may be large).

  • jQuery selective hover

    - by Vitor
    Hello everyone, I'm trying to do a simple task with jQuery: I have a list of words which, when hovered, should fadeIn its corresponding image. For example: <a href="#" class="yellow">Yellow</a> <a href="#" class="blue">Blue</a> <a href="#" class="green">Green</a> <img src="yellow.jpg" class="yellow"> <img src="blue.jpg" class="blue"> <img src="green.jpg" class="green"> I'm currently doing it this way for each link/image: $('a.yellow').hover( function () { $('img.yellow').fadeIn('fast'); }, function () { $('img.yellow').fadeOut('fast'); }); The method above works fine, but as I'm still learning, I guess there's a better way to do that instead of repeating functions. Can anyone give me some light here? How can I improve this code?

  • Which Database to choose?

    - by Sundar
    I have the following criteria Database should be protected with a username and password. It should not be possible to copy the database file and use it else were like MS Access. There will be no central database server. Each machine will run their own database server locally and user will initiate synchronization. Concept is inspired from distributed version control system like Git. So it should have good replication support. Strong consistency is not needed. Users will synchronize each other database when they need. In case of conflicts it should be possible to find the conflict and present it (from application) to the user for fixing it. Revisions of data if available it will be good. e.g. Entire history of change to a invoice. I explored document oriented database and inclined towards the same. But I dont know what to choose. Database is small it will not reach even 1GB in the next few years (say 3 years). Please feel free to suggest any database which you think might be suitable. Any pointers is highly appreciated. Thanks in advance.

  • GUI Design - Roleselection with two lists, selected roles on the right, or left list?

    - by subes
    Hi, image two lists for selecting roles for a new user creation in an administrator frontend. One list has all available roles in it and another has the selected roles in it. Between those lists are buttons to move elements from one list to another. Thus the layout is horizontal with [List] [Buttons] [List]. Now to the question: Should the selected elements be on the left, or the right list? Intuitively some people I asked say, that the selected elements have to be on the right list. But some other people follow some sort of guideline that says, that the more important stuff in a frontend has to be on the left side. Also they think the selected elements are more important than the non-selected and so the selected ones have to be on the left side. Whats your opinion?

    Hey guys, I have an Excel document which has a list of students and their group names. I have another sheet within the the same excel document which is called comments. In this sheet, I would like to have a list of individual team names listed. There are 65 students and 14 defined groups. Is there a way to select the 14 group names, without repitition? Cell B3-B67 have the student names. Cell C3-C67 have the team names. The team names are entered against each student. I know in SQL I could use something like select distinct(team_name) but in Excel, how can I replicate this? Cheers, Alks.

  • How to select an element by Class instead of ID in ASP.NET?

    - by firedrawndagger
    I have a few scatter elements which I am grouping together using a class like so - . In my code behind, using C# I want to hide these elements, using something like instructions.Visible = false;. However I realize I can only do this in codebehind if I use ID but this will result in invalid HTML/CSS Selector since you can't have multiple ID's with the same ID name... Alternatively is there another way to group the controls if not by class?

How come 0-indexed item didn't change its position & size? How to solve this ?
