  • Implementing ma? osx loop device driver.

    - by Inso Reiges
    Hello, I am aware that there is a native implementation of loop device system on osx, the hdiutil/hdix driver. But due to a number of reasons i need to roll out my own custom loop driver. Since hdix is closed-source can anyone give some starting pointers, links, advises, etc. on the subject? I had expirience implementing loop drivers on linux and windows but i don't really have a clue where to start from on osx. The basic functionality i need to implement is the same: given any file on disk, simulate a virtual block device interface for it. I also would like my loop driver to use all the native partition filter stacking available for real and hdix virtual block devices on osx.

  • jQuery tabs - multiple sets on on page

    - by Jonny Wood
    This is kind of a follow on from a previous question I posted but I've not been able to get it to work.. I'm trying to use multiple sets of tabs (jQuery) on one page. This is the code I had for one set of tabs which works great: $('div.tabs div.tab').hide(); $('div.tabs div:first').show(); $('div.tabs ul.htabs li:first a').addClass('current'); $('div.tabs ul.htabs li a').click(function(){ $('div.tabs ul.htabs li a').removeClass('current'); $(this).addClass('current'); var currentTab = $(this).attr('href'); $('div.tabs div.tab').hide(); $(currentTab).show(); return false; }); To use more than one set on the page I assigned #id's to each tab-set and tried to impliment this with: $.each(['#tabs-1', '#tabs-2', '#tabs-3' ], function(id) { $(id + 'div.tab').hide(); $(id + 'div:first').show(); $(id + 'ul.htabs li:first a').addClass('current'); $(id + 'ul.htabs li a').click(function(){ $(id + 'ul.htabs li a').removeClass('current'); $(this).addClass('current'); var currentTab = $(this).attr('href'); $(id + 'div.tab').hide(); $(currentTab).show(); return false; }); }); Obviously I'm doing something wrong here but as a jQuery newcomer I'm stumped!

  • Delphi / ADO : how to get result of Execute() ?

    - by mawg
    I have declared AdoConnection : TADOConnection; and successfully connected to the default "mysql" database (so, no need to pass that code). Now, taking baby steps to learn, I would like to AdoConnection.Execute('SHOW DATABASES', cmdText); which seems to work ok, in the sense that it doesn't throw an exception, but I am such a n00b that I don't know how I can examine the result of the command :-/ Halp!

  • rich:fileupload inside rich:modalpanel doesnt send uploadcomplete event

    - by Ben
    I'm trying to use the rich:fileupload from inside a rich:modalpanel component. The problem is that, when inside modalpanel, fileupload doesn't doesnt start the fileuploadeventlistener method. The same fileupload component works fine outside of modalpanel. (Although it doesn't rerender the components I ask it to, but that's another topic.) I could find this issue and similar ones on search for "fileupload modalpanel" but no answers. My code is added from a backing bean, but this illustrates it: <a4j:form id="overlayForm"> <rich:modalPanel> <rich:fileupload fileuploadeventlistener="#{mrBean.uploadCompleteListener}"/> </rich:modalPanel> </a4j:form>

  • jquery mouseover animation jumping

    - by Sylph
    Hi all, I have a table which is looped in <li>. On mouseover each row, there will be a border shown, and the row id="resFunc" will be displayed. However, in IE, the animation jumps up and down. Anyone has similar experience or solution to solve this? Thanks in advance! <div id="resDetails" align="left"> <table width="400px" class="resBox"> <tr> <td><b>{creator}</b></td> </tr> <tr> <td colspan="2"><div class="edit{_id}" id="{_id}"> {title}</div></td> </tr> <tr style="display:none" class="url{_id}"> <td colspan="2" class="edit_url{_id}" id="{_id}">{url}</td> </tr> <tr> <td colspan="2" class="edit_area{_id}" id="{_id}">{description}</td> </tr> <tr id="resFunc{_id}" style="display:none"> <td colspan="2" align="right"><b><a href="#" id="{_id}" class="editRes">Edit</a>&nbsp;&nbsp; <a href="#" class="deleteResource" id="{_id}">Delete</a></b> </td> </tr> </table><br> </div> This is the onClick function :- $(".resBox").mouseover(function(){ var id = $(this).attr("id"); $(this).addClass('highlight'); $('#resFunc'+id).show(); }); $(".resBox").mouseout(function(){ var id = $(this).attr("id"); $(this).removeClass('highlight'); $('#resFunc'+id).hide(); });

  • JNI_CreateJavaVM: Buffer overrun if I throw an exception in case of failure

    - by Dominik Fretz
    Hi, In a C++ project, I use the JNI invocation API to launch a JVM. I've done a little wrapper arount the JVM so I can use all the needed parts in a OO fashion. So far that works great. Now, if the JVM does not start (JNI_CreateJavaVM returns a value < 0) I'd like to raise an exception within my C++ code.But if I throw an exception after JNI_CreateJavaVM, I get a buffer overrun. If I raise the exception without the JNI_CreateJavaVM call, it works as expected. Does anyone have a clue on what the issue could be here? Or how to debug this? Environment: Windows, Visual Studio 2008 JDK: jrockit27.6jdk16005, but happens with SUN stock one as well Cheers Dominik

  • Help regarding database and logic layer for my ASP.NET MVC application

    - by Ismail S
    I'm going to start a new project which is going to be small initially but may grow to big over the years. I'm strongly convinced that I'm going to use ASP.NET MVC with jQuery for UI. I want to go for MySQL as database for some reasons but worried on few things. I've a good years of experience working on SQL Server databases and on one project I've had a bad experience creating and managing stored procedures on MySQL database. I'm totally new to Linq but I see that it is easier to use once you are familiar with it. First thing is that accessing data should be easy. So I thought I should use MySQL to Linq but somewhere I read that it is not directly supported but MySQL .NET connector adds support for EntityFramework. I don't know what are the pros and cons of it. I would love if I can implement repository pattern. Will it be possible if I use Entity Framework? I'm not clear on how I should go about all this or I should just forget every thing and directly use SQL to Linq on SQL Server. I'm also concerned about the performance. Someone told me that if we use Entity framework it fetches lot of data and then filter it. Is that right?
