  • const object and const constructor

    - by Muhammad alaa
    Is there any way to know if an object is a const object or regular object, for instance consider the following class class String { String(const char* str); }; if user create a const object from String then there is no reason to copy the passed native string and that because he will not make any manipulation on it, the only thing he will do is get string size, string search and other functions that will not change the string.

  • MSSQL 2005: Update rows in a specified order (like ORDER BY)?

    - by JMTyler
    I want to update rows of a table in a specific order, like one would expect if including an ORDER BY clause, but MS SQL does not support the ORDER BY clause in UPDATE queries. I have checked out this question which supplied a nice solution, but my query is a bit more complicated than the one specified there. UPDATE TableA AS Parent SET Parent.ColA = Parent.ColA + (SELECT TOP 1 Child.ColA FROM TableA AS Child WHERE Child.ParentColB = Parent.ColB ORDER BY Child.Priority) ORDER BY Parent.Depth DESC; So, what I'm hoping that you'll notice is that a single table (TableA) contains a hierarchy of rows, wherein one row can be the parent or child of any other row. The rows need to be updated in order from the deepest child up to the root parent. This is because TableA.ColA must contain an up-to-date concatenation of its own current value with the values of its children (I realize this query only concats with one child, but that is for the sake of simplicity - the purpose of the example in this question does not necessitate any more verbosity), therefore the query must update from the bottom up. The solution suggested in the question I noted above is as follows: UPDATE messages SET status=10 WHERE ID in (SELECT TOP (10) Id FROM Table WHERE status=0 ORDER BY priority DESC ); The reason that I don't think I can use this solution is because I am referencing column values from the parent table inside my subquery (see WHERE Child.ParentColB = Parent.ColB), and I don't think two sibling subqueries would have access to each others' data. So far I have only determined one way to merge that suggested solution with my current problem, and I don't think it works. UPDATE TableA AS Parent SET Parent.ColA = Parent.ColA + (SELECT TOP 1 Child.ColA FROM TableA AS Child WHERE Child.ParentColB = Parent.ColB ORDER BY Child.Priority) WHERE Parent.Id IN (SELECT Id FROM TableA ORDER BY Parent.Depth DESC); The WHERE..IN subquery will not actually return a subset of the rows, it will just return the full list of IDs in the order that I want. However (I don't know for sure - please tell me if I'm wrong) I think that the WHERE..IN clause will not care about the order of IDs within the parentheses - it will just check the ID of the row it currently wants to update to see if it's in that list (which, they all are) in whatever order it is already trying to update... Which would just be a total waste of cycles, because it wouldn't change anything. So, in conclusion, I have looked around and can't seem to figure out a way to update in a specified order (and included the reason I need to update in that order, because I am sure I would otherwise get the ever-so-useful "why?" answers) and I am now hitting up Stack Overflow to see if any of you gurus out there who know more about SQL than I do (which isn't saying much) know of an efficient way to do this. It's particularly important that I only use a single query to complete this action. A long question, but I wanted to cover my bases and give you guys as much info to feed off of as possible. :) Any thoughts?

  • How can I deploy an Adobe Air application including the runtime in a single file executable?

    - by Lozzer
    I am using 7zsfx [Link] to package Java apps together with a JRE as a single file executable. Is it possible to do something similar with Adobe AIR apps if I get a license from Adobe to distribute the runtime? Also, does anybody have any alternative ideas for deploying Adobe Air apps with an embedded runtime? (Reason: Target computers may not have the Air runtime installed, and target users may not have permissions to download and install the runtime.)

  • ASP.NET MVC 2 - Setting id of Html.Form

    - by Justin
    Hey, How do you set the id of an Html.Form in ASP.NET MVC 2? I tried this: <% using (Html.BeginForm("Save", "Clients", new { id = "SubmitForm" })) {%> But it doesn't work, my form still doesn't have an id property: <form action="/TothSolutions/Secure/Clients/Save/SubmitForm" method="post"> I'm guessing this worked in ASP.NET MVC 1 but not 2. The reason I need the id property set is so that I can do jQuery validation on the form: $("#myForm").validate etc... Thanks, Justin

  • Facebook Thumbnails Issue Traced to safe_image.php

    - by talkinggoat
    For some reason, facebook's safe_image.php script isn't generating thumbnails, properly. It's generating a 1x1 image... even though the correct image is linked in the script's parameters. Example: <img class="img" alt="" src="https://s-external.ak.fbcdn.net /safe_image.php?d=AQBtrCt_Es_KsED0&w=90&h=90&url=http%3A%2F %2Fwww.southlapatriots.info%2Fimages%2FScamra%2FJayCastilleCouncil2.jpg" The linked image is correct, but it is still only generating a 1x1 image.

  • JQUERY animate Delay?

    - by AnApprentice
    I'm using JQUERY animate to show a banner at the top of the page, which is a DIV that is set to top -60 to hide it. I'm using the following JS call to show the div: // Animation $('#message-dock').animate({ top: 0 }, 500, function() { // Animation complete. }); What I can't figure out is for some reason there is an unwanted delay before I start seeing the div and I can't figure out why? Any Ideas?

  • why does Visual Studio not enforce try-catch-block implementation?

    - by Pedro
    Coming from Eclipse/Java, I noticed that in VisualStudio/C# it is not mandatory to care about Exceptions. While Eclipse forces the user to implement a try-catch-block or to add a throws declaration, this is not the case in Visual Studio. What is the reason Visual Studio doesn't inform about unhandled exceptions? Can I configure Visual Studio to force me to implement try-catch-blocks, or at least add a compiler-warning?

  • Why is "copy and paste" of code dangerous?

    - by Yigang Wu
    Sometimes, my boss will complain us why we need so long time to implement a feature. Actually, the feature has been implemented in other AP before, you just need to copy and paste codes from there. The cost should be low. It's really a hard question, because copy and paste codes is not a easy thing from my point. Do you have any good reason to explain your boss who doesn't know technology?

  • Are there legitimate uses for JavaScript's "with" statement?

    - by Shog9
    Alan Storm's comments in response to my answer regarding the with statement got me thinking. I've seldom found a reason to use this particular language feature, and had never given much thought to how it might cause trouble. Now, I'm curious as to how I might make effective use of with, while avoiding its pitfalls... So my question is, where have you found the with statement useful?

  • Value object or not for 3d points ?

    - by Stefano Borini
    I need to develop a geometry library in python, describing points, lines and planes in 3d space, and various geometry operations. Related to my previous question. The main issue in the design is if these entities should have identity or not. I was wondering if there's a similar library out there (developed in another language) to take inspiration from, what is the chosen design, and in particular the reason for one choice vs. the other.

  • HTML File upload field style

    - by Steven1350
    I am trying to create a file upload field that has a little bit of style to it, but I seem to be having problems finding examples of this. I know part of the reason is that the field itself varies from browser to browser. Any ideas how to do this? Or is there a way to do this without using a file element of a form that can be styled?

  • UIAlertViewDelegate clickedButtonAtIndex: usefulness?

    - by Ed Marty
    The UIAlertViewDelegate protocol defines two methods, alertView:clickedButtonAtIndex: and alertView:didDismissWithButtonIndex:, which seem to me to be identical in usefulness. Why is there a clickedButtonAtIndex and a didDismissButtonWithIndex when they both do the same thing? I realize there is also a willDismissButtonWithIndex that happens before the alert view is dismissed, but is there any reason to use clickedButtonAtIndex instead of didDismissButtonWithIndex?

    I keep hearing from associates about grid computing which, from what I can gather, is highly distributed stuff along the lines of SETI@Home. Is anyone working on these sort of systems for business use? My interest is in figuring out if there's a commercial reason for starting software development in this field.
