  • How to secure the communication between an MSSQL database and a c# administrative tool?

    - by citronas
    How can I secure the communication between a C# programm running locally on my computer and a MSSQL Server in a hosted environment? I have an asp.net application that is secured by SSL encryption. So using the asp.net from an open wlan connection is no problem. How can I achieve the same kind of encryption for my administrative tool? Would it be best to write a service? But how would that connection to the service be secured?

  • Java text to applet converter ... is there such a thing?

    - by Jahkr
    Let's say you have this program: public class sample public static void main(String args[]) { System.out.println("Hello world!"); } } ... is there a converter that will turn it into this: import java.applet.Applet; import javax.swing.*; public class sample extends JApplet { public static JTextArea area; public void init() { area = new JTextArea(); add(area); area.append("Hello world!"); } } I mean, I can do it by hand... but it would take some time.

  • Ruby on Rails Truncate text - can I use it for a combination of title and content?

    - by Quhby
    I have <%=link_to topic.title, topic_path(topic) % - <%= truncate(topic.description_without_embed, :length=50, :omission ="...") % But what I really want to do is to truncate both the title and the post to 50 characters. How can this be done? The output should look something like Lorem ipsum dolor sit amet, consectetur adipiscing elit. - Curabitur eu dolor est, id pharetra lectus. Phasellus nec feugiat dolor. Curabitur feugiat ultrices leo ut egestas. Nullam nec nisi in ligula feugiat placerat. Ut adipiscing urna consequat tortor euismod pretium. Maecenas eget quam aliquet orci blandit eleifend eu et quam. Donec. instead of Lorem ipsum dolor sit amet, consectetur adipiscing elit. - Lorem ipsum dolor sit amet, consectetur adipiscing elit. Curabitur eu dolor est, id pharetra lectus. Phasellus nec feugiat dolor. Curabitur feugiat ultrices leo ut egestas. Nullam nec nisi in ligula feugiat placerat. Ut adipiscing urna consequat tortor euismod pretium. Maecenas eget quam aliquet orci blandit eleifend eu et quam. Donec. I don't need to use the truncate method, any method would be helpful. Thanks.

  • Unresponsive UI when using BeginInvoke

    - by Kazoom
    Bckground I have a networked application written in C#. my server program has a UI and several communication threads, that read from tcp sockets and display messages on controller UI. Communication with each client is done through a seprate thread. When i recieve some stream of messages from one client , the thread for that client writes on UI, which is a richtextbox on a Form. I call SetTextHelper(string text) method of the form. which looks like this private delegate void MyTextUpdateHandler(string text); public void SetTextHelper(string text) { BeginInvoke(new MyTextUpdateHandler(SetText), new object[] { text }); } public setText(string text) { richtext.Text= text; } Question - If i use BeginInvoke my UI is entirely unresponsive when i m writing large stream of data to UI - Invoke solves that problem, but i read that for multi threaded environment where many thereads are sharing same resource Invoke can lead to deadlocks I share the common ichtextbox between around 16 threads - What would be a good desing for my situation?

  • Huge AS 3.0 Export Frame

    - by goorj
    I am creating a very simple flash animation with no code or complex effects, just text and simple tweens (Flash CS5) But I have problems reducing the size of my swf. From the generated size report, it looks like it has to do with fonts and/or exported actionscript classes. The frame with AS 3.0 Classes is over 100K, and even though I am only using one fonts, the same characters are embedded/exported multiple times My questions are: Do embedding of mixed TLF/Classic text (or mixing other text properties, spacing/kerning etc) require the same characters to be embedded twice? Do text transformations on TLF text (rotation and different transformations not available in classic text) require embedding of ("internal") AS3 classes that will increase the size of the .swf? (even though none of these classes are explicitly used by me, there are no scripts in the fla project) I have tried removing all the text instances one by one, and at one point, the swf is reduced to only 5-6K, but I am not able to pinpoint exactly what causes the ballooning of the swf

  • Updating label using jquery and code behind

    - by Zaps
    Hi, I have a label on a page and I'm updating the text property of the label when text is changed in a textbox. I'm updating the label like so: $myLabel.text("hello"); The text is being displayed correctly on the screen butwhen I try to save the text value to an object in the code behind (When I press a button) the text property of the label is "" and not "hello". var myLabel = myLabel.Text; //the var myLabel is "" when it should be "hello" Any ideas as to why this would be? Thanks in advance, Zaps

  • For Qt 4.6.x, how to auto-size text to fit in a specified width?

    - by darenchow
    Inside of my QGraphicsRectItem::paint(), I am trying to draw the name of the item within its rect(). However, for each of the different items, they can be of variable width and similarly names can be of variable length. Currently I am starting with a maximum font size, checking if it fits and decrementing it until I find a font size that fits. So far, I haven't been able to find a quick and easy way to do this. Is there a better, or more efficient way to do this? Thanks! void checkFontSize(QPainter *painter, const QString& name) { // check the font size - need a better algorithm... this could take awhile while (painter->fontMetrics().width(name) > rect().width()) { int newsize = painter->font().pointSize() - 1; painter->setFont(QFont(painter->font().family(), newsize)); } }

  • How can I use Perl to grab text from a web page that is dynamically generated with JavaScript?

    - by bstullkid
    There is a website I am trying to pull information from in Perl, however the section of the page I need is being generated using javascript so all you see in the source is: <div id="results"></div> I need to somehow pull out the contents of that div and save it to a file using Perl/proxies/whatever. e.g. the information I want to save would be document.getElementById('results').innerHTML; I am not sure if this is possible or if anyone had any ideas or a way to do this. I was using a lynx source dump for other pages but since I cant straight forward screen scrape this page I came here to ask about it! If anyone is interested, the page is http://downloadcenter.trendmicro.com/index.php?clk=left_nav&clkval=pattern_file&regs=NABU and the info I am trying to get is the row about the ConsumerOPR

  • How can I pull data from a SQL Database that spans an academic year?

    - by Eric Reynolds
    Basically, I want to pull data from August to May for a given set of dates. Using the between operator works as long as I do not cross the year marker (i.e. BETWEEN 8 AND 12 works -- BETWEEN 8 AND 5 does not). Is there any way to pull this data? Here is the SQL Query I wrote: SELECT count(*), MONTH(DateTime) FROM Downloads WHERE YEAR(DateTime) BETWEEN 2009 AND 2010 AND MONTH(DateTime) BETWEEN 8 AND 5 GROUP BY MONTH(DateTime) ORDER BY MONTH(DateTime)" Any help is appreciated. Thanks, Eric R.

  • How can I get the text color of a button using the Substance LaF?

    - by DR
    In my Java application I have to custom-paint a control and for that I need to use the same font colors as JButton. (Enabled an disabled) I don't want to to hard-code them, because the user can change the Substance skin at runtime. I'm aware of the ColorSchemes but I'm not sure how to proceed once I have the color scheme of the current skin. Also the Substance documentation says something about creating your own color scheme, but I just can't figure out the way to retrieve a certain color.

  • How could I cache images that I'm pulling from a magento database through ajax?

    - by wes
    Here's script being called through ajax: <?php require_once '../app/Mage.php'; umask(0); /* not Mage::run(); */ Mage::app('default'); $cat_id = ($_POST['cat_id']) ? $_POST['cat_id'] : NULL; try { $category = new Mage_Catalog_Model_Category(); $category->load($cat_id); $collection = $category->getProductCollection(); $output = '<ul>'; foreach ($collection as $product) { $cProduct = Mage::getModel('catalog/product'); $cProduct->load($product->getId()); $output .= '<li><img id="'.$product->getId().'" src="' . (string)Mage::helper('catalog/image')->init($cProduct, 'small_image')->resize(75) . '" class="thumb" /></li>'; } $output .= '</ul>'; echo $output; } catch (Exception $e) { echo 'Caught exception: ', $e->getMessage(), "\n"; } I'm just passing in the Category ID, which I've tacked onto the navigation links, then doing some work to eventually just pass back all product images in that category. I'm using this on a drag and drop build-a-bracelet type of application, and the amount of images returned is sometimes in the 500s. So it get's pretty held up during transmission, sometimes 10 seconds or so. I know I'd do good by caching them some way, just not sure how to go about it. Any help is much appreciated. Thanks. -Wes

  • Zip Code to City/State and vice-versa in a database?

    - by Simucal
    I'm new to SQL and relational databases and I have what I would imagine is a common problem. I'm making a website and when each user submits a post they have to provide a location in either a zip code or a City/State. What is the best practice for handling this? Do I simply create a Zip Code and City and State table and query against them or are there ready made solutions for handling this? I'm using SQL Server 2005 if it makes a difference. I need to be able to retrieve a zip code given a city/state or I need to be able to spit out the city state given a zip code.
