  • RAII tutorial for c++

    - by Joe Bloggs
    Hi. I'd like to learn how to use RAII in c++. I think I know what it is, but have no idea how to implement it in my programs. A quick google search did not show any nice tutorials. Does any one have any nice links to teach me RAII?

  • Creating a contact form using divs with 4 extra divs for "Corners"?

    - by mark smith
    Hi there, i have tried to create a contact form (a standard form, square in nature but with rounded corners)... I can't use the CSS3 specs so i have an image for each corner.. I have set the images on the background-image and no repeat but it seems if the div is empty then it doesn't display, is there a hack - although prefer an alternative clean method :-) So on the top level i presume i have 1 div for the Upper-Left (corner) and then the upper-middle (just has a color assigned) and then a div for the upper-right (corner) .. so i presume i need to float all these to the left??? Or am i missing something? Thanks in advance

  • Performance hit from C++ style casts?

    - by Trevor Boyd Smith
    I am new to C++ style casts and I am worried that using C++ style casts will ruin the performance of my application because I have a real-time-critical deadline in my interrupt-service-routine. I heard that some casts will even throw exceptions! I would like to use the C++ style casts because it would make my code more "robust". However, if there is any performance hit then I will probably not use C++ style casts and will instead spend more time testing the code that uses C-style casts. Has anyone done any rigorous testing/profiling to compare the performance of C++ style casts to C style casts? What were your results? What conclusions did you draw?

  • How to Store and Retrieve Images Using SQL Server (Server Management Studio)

    - by Joe Majewski
    I am having difficulties when trying to insert files into a SQL Server database. I'll try to break this down as best as I can: What data type should I be using to store image files (jpeg/png/gif/etc)? Right now my table is using the image data type, but I am curious if varbinary would be a better option. How would I go about inserting the image into the database? Does Microsoft SQL Server Management Studio have any built in functions that allow insertions of files into tables? If so, how is that done? Also, how could this be done through the use of an HTML form with PHP handling the input data and placing it into the table? How would I fetch the image from the table and display it on the page? I understand how to SELECT the cell's contents, but how would I go about translating that into a picture. Would I have to have a header(Content type: image/jpeg)? I have no problem doing any of these things with MySQL, but the SQL Server environment is still new to me, and I am working on a project for my job that requires the use of stored procedures to grab various data. Any and all help is appreciated.

  • How to add value to second column using wxListCtrl in wxWidgets (C++ code)??

    - by azm882
    I've following code: int column_width = 100; long indx1 = alist-InsertColumn(0, L"User Name", wxLIST_FORMAT_LEFT, column_width); long indx2 = alist-InsertColumn(1, L"User Id", wxLIST_FORMAT_LEFT, column_width); long itemIndex1 = alist-InsertItem(indx1, L"John Smith", -1); alist-SetItem(indx1, 1, L"jsmith"); I expect to see two columns with User Name and User Id as heading with "My Name" and "My Id" as values on the first row. Instead I only see "John Smith" under column User Name but nothing under User ID column. Here is a link to the snapshot showing the result: http://drop.io/agtyt6s Thanks!

  • Is it possible to virtualize war file execution without separate J2EE container deployments?

    - by Smith
    Let's say I want to allow my developers to upload their war files to a web app (not the application server itself) running on our intranet and that web app would then run those wars as if they were separate apps deployed individually in our J2EE container. In other words, we are not actually deploying the wars as separate apps in the container - they are simply running side-by-side inside this one web app that acts like a J2EE container. Is that possible? Something like a war virtualization app?

  • Help Installing phpMyAdmin on Linux Server

    - by Joe Majewski
    I constantly get this error when attempting to view index.php in the phpMyAdmin folder I have setup: Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly. I am using subversion with three co-workers and I am trying to install this on my repository, which is at /svni3/myusername/intranet/ on our linux development server. I do have shell access so I would be able to install it somewhere else if that may be causing the problem. My config.inc.php file looks like this (only the things I changed): $cfg['blowfish_secret'] = 'blah'; $cfg['Servers'][$i]['auth_type'] = 'cookie'; //$cfg['Servers'][$i]['user'] = 'username'; //$cfg['Servers'][$i]['password'] = 'password'; $cfg['Servers'][$i]['host'] = 'localhost'; Other helpful information??? When I ping localhost it works. When I run the command "ls -l /var/lib/php": drwxrwx--- 2 root apache 4096 2009-04-17 02:31 session If there's anything else that may be helpful let me know; this has been plaguing me for a few hours now.

  • Embedded Lua on iPhone. What's new and what does it mean?

    - by John Smith
    Apparently Apple has changed some term in the agreement again. From http://www.appleoutsider.com/2010/06/10/hello-lua/ section 3.3.2 is now Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application. instead of the original No interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). I am more interested in embedding Lua, but other people have other embeddings they want to make. I am wondering how you ask for permission, and what they mean by the terms "minor features" and "consistent" and how will Apple interpret this section? It seems to have enough loopholes to drive a real firetruck through.

  • What FPGAs (Field-Programmable Gate Arrays) can one buy to experiment with at home?

    - by Joe Blow
    What the heck is an FPGA -- where can I buy one? What sort of system do you need to experiment with them? How to program them? Can you "load" if that's the right terms an FPGA using an ordinary mac or perhaps other *nix or windoze computer? Where can I buy some FPGAs today to experiment with ??! Are they expensive this only available to industry or can I buy one today? Does anyone know about this? Thanks! I have become interested in FPGAs after reading this question...

  • Is there anything inherently wrong with long variable/method names in Java?

    - by Doug Smith
    I know this is probably is a question of personal opinion, but I want to know what's standard practice and what would be frowned upon. One of my profs in university always seems to make his variable and method names as short as possible (getAmt() instead of getAmount) for instance. I have no objection to this, but personally, I prefer to have mine a little longer if it adds descriptiveness so the person reading it won't have to check or refer to documentation. For instance, we made a method that given a list of players, returns the player who scored the most goals. I made the method getPlayerWithMostGoals(), is this wrong? I toiled over choosing a way to make it shorter for awhile, but then I thought "why?". It gets the point across clearly and Eclipse makes it easy to autocomplete it when I type. I'm just wondering if the short variable names are a piece of the past due to needing everything to be as small as possible to be efficient. Is this still a requirement?

  • How do I style jQuery Combobox to look like a normal select dropdown

    - by Joe T
    Hi everyone. I am making use of jQuery 1.4.4 and jQuery UI 1.8.7 in a legacy code base. I have added a few combobox() ui-widgets, these comboboxes live along side normal <select> dropdowns. I am finding it difficult to get the two elements to look the same, i.e. the unstyled <select> with it's Internet Explorer / Windows based style and the most basic jQuery UI Themed ui-widget combobox. The screenshot shows an unstyled <select> on the left and a jQuery ui-widget combobox on the right: Is it possible to make the two look the same?

  • Changing all CSS styles with a property via Jquery

    - by Joe
    On a page I include some css eg: <style type='test/css'> .myBox{ color:#000000; border:#FFFFFF; padding:4px; } .myBox2{ color:#000000; border:#FFFFFF; padding:4px; } </style> I want to then change the "color" property set within both myBox and myBox2 in jquery, without knowing the actual name (myBox, myBox2) of the css style. In otherwords, I want to update ALL css styles on the page where color = certain value, and then also update border where = certain value. An example (not valid code) might be: $("all css [color:#000000]").html("#FF0000"); How could this be possible using jquery?

  • Database design efficiency with 1 to many relationships limited 1 to 3

    - by Joe
    This is in mysql, but its a database design issue. If you have a one to many relationship, like a bank customer to bank-accounts, typically you would have the table that records the bank-account information have a foreign key that keeps track of the relationship between account and customer. Now this follows the 3rd normal form thing and is a widely accepted way of doing it. Now lets say that you are going to limit a user to only having 3 accounts. The current database implementation will support this and nothing would need to change. But another way to do this would have 3 coloms in the account table that have the id of the 3 respective accounts in them. By the way this violates 1st normal form of db design. The question is what would be the advantage and disadvantages of having the user account relationship recored in this way over the traditional?

  • In PHP, imagepng() accepts a filter parameter. How do these filters affect the function's output?

    - by Joe Lencioni
    How do these filters affect the output of imagepng() in PHP? PNG_NO_FILTER PNG_FILTER_NONE PNG_FILTER_SUB PNG_FILTER_UP PNG_FILTER_AVG PNG_FILTER_PAETH PNG_ALL_FILTERS The documentation simply says, "A special PNG filter, used by the imagepng() function" for each of them. It seems that using PNG_NO_FILTER will reduce the filesize of the output, but other than that, I am unsure as to how it is affected. Any insight would be really appreciated.
