  • How do you escape parentheses in a Binding indexer

    - by Chris S
    I have the following XAML: <Grid x:Name="LayoutRoot" Background="White" DataContext="{Binding Source={StaticResource MyDataKey}}"> <TextBox Name="_myId" Text="{Binding MyDictionary[(Textbox.Name)]" /> </Grid> But it thinks the key in my dictionary is called "(Textbox.Name)", instead of "_myId". The format below works, where I have a property in my class called "_myId": <TextBox Name="_myId" Text="{Binding (Textbox.Name)" /> I've tried using ^ and \ to escape the brackets. Is this syntax supported? I'm trying to avoid duplication of the name in two attributes.

  • Casting a Calculated Column in a MySQL view.

    - by Chris Brent
    I have a view that contains a calculated column. Is there are a way to cast it as a CHAR or VARCHAR rather than a VARBINARY ? Obviously, I have tried using CAST(... as CHAR) but it gives an error. Here is a simple replicable example. CREATE VIEW view_example AS SELECT concat_ws('_', lpad(9, 3,'0'), lpad(1,3,'0'), date_format(now(),'%Y%m%d%H%i%S')) AS calculated_field_id; This is how my view is created: describe view_example; +---------------------+---------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +---------------------+---------------+------+-----+---------+-------+ | calculated_field_id | varbinary(27) | YES | | NULL | | +---------------------+---------------+------+-----+---------+-------+ select version(); +-----------------------+ | version() | +-----------------------+ | 5.0.51a-community-log | +-----------------------+

  • Progressive enhancement of anchor tags to avoid onclick="return false;"

    - by Chris Beck
    Unobtrusive JS suggests that we don't have any onclick attributes in our HTML templates. <a href="/controller/foo/1">View Foo 1</a> A most basic progressive enhancement is to convert an that anchor tag to use XHR to retrieve a DOM fragment. So, I write JS to add an event listener for a."click" then make an XHR to a.href. Alas, the browser still wants to navigate to "/controller/foo". So, I write JS to dynamically inject a.onclick = "return false;". Still unobtrusive (I guess), but now I'm paying the the cost of an extra event handler. To avoid the cost of 2 event listeners, I could shove my function call into the onclick attribute <a href="/controller/foo/1" onclick="myXHRFcn(); return false;"> But that's grodo for all sorts of reasons. To make it more interesting, I might have 100 anchor tags that I want to enhance. A better pattern is a single listener on a parent node that relies on event bubbling. That's cool, but how do I short circuit the browser from navigating to the URL without this on every anchor node? onclick="return false;" Manipulating the href is not an option. It must stay intact so the context menu options to copy or open in new page work as expected.

  • Container<ImplementerOfIInterface> is not Container<IInterface>. Why not?

    - by Chris Simmons
    Why wouldn't DoesntWork() work below? The error is: Cannot implicitly convert type 'List' to 'IEnumerable'. An explicit conversion exists (are you missing a cast?). I know this is something about generic/templates I'm not getting, but List is IEnumerable and Implementer is an IInterface. I don't see why this needs to be casted (or if it really can be). public interface IInterface { // ... } public class Implementer : IInterface { // ... } IEnumerable<IInterface> DoesntWork() { List<Implementer> result = new List<Implementer>(); return result; }

  • Changing a Select dropdown with a jquery ui slider

    - by Chris J. Lee
    Trying to set a select dropdown with a slider. You move the jquery ui slider and then it will change the selection of the other two dropdowns. is there a current method in jquery that would set these options? Current dropdown: <select id="alert-options-frequency-opts"> <option value=""></option> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> <option value="6">6</option> <option value="7">7</option> <option value="8">8</option> <option value="9">9</option> <option value="10">10</option> </select>

  • Is using .h as a header for a c++ file wrong?

    - by Chris Huang-Leaver
    Is using .h as a header for a c++ file wrong? I see it all over the place, especially with code written in the "C style". I noticed that Emacs always selects C highlighting style for a .h header, but c++ for hpp or hh. Is it actually "wrong" to label your headers .h or is it just something which annoys me? EDIT: There is a good (ish) reason why this annoys me, if I have project files labelled, 'hpp & cpp' I can get away with 'grep something *pp' etc. otherwise I have to type '.h cpp'

  • Autopopulate from Select box from database

    - by Chris Spalton
    hope you can help, please forgive any poor coding or anytihng, I'm new to this and just hacking my way through to get things to work. That said, on one of my projects I have this code, which successfully populates the dropdown from a database when the page is loaded: <select name="Region" id="Region"> <option value="">-- Select Region --</option> <?php $region=$POST['Region']; if ($region); { $regionquery = "SELECT DISTINCT REGION FROM Sales_Execs "; $regionresult = mysql_query($regionquery); while($row = mysql_fetch_array($regionresult)) { echo "<option value=\"".$row['REGION']."\">".$row['REGION']."</option>\n "; } } ?> <script type="text/javascript"> document.getElementById('Region').value = <?php echo json_encode(trim($_POST['Region']));?>; </script> </select> On my next project that I'm working on now, I need to do the same thing, so I copied the above code amended, and placed in my new project: <select name="Sales_Exec" id="Sales_Exec"> <option value="">-- Select SE --</option> <?php $salesexec=$POST['Sales_Exec']; if ($salesexec); { $salesexecquery = "SELECT DISTINCT Assigned FROM Data "; $salesexecresult = mysql_query($salesexecquery); while($row = mysql_fetch_array($salesexecresult)) { echo "<option value=\"".$row['ASSIGNED']."\">".$row['ASSIGNED']."</option>\n "; } } ?> <script type="text/javascript"> document.getElementById('Sales_Exec').value = <?php echo json_encode(trim($_POST['Sales_Exec']));?>; </script> </select> This second chunk of code doesn't work... and I can't work out why as it seems I've copied it all and amended all the neccersary parts, can anyone spot what is wrong? Thankyou!

  • Including full LaTeX documents within others.

    - by Chris Clarke
    I'm currently finishing off my dissertation, and would like to be able to include some documents within my LaTeX document. The files I'd like to include are weekly reports done in LaTeX to my supervisor. Obviously all documents are page numbered seperately. I would like them to be included in the final document. I could concatenate all the final PDFs using GhostScript or some other tool, but I would like to have consistent numbering throughout the document. I have tried including the LaTeX from each document in the main document, but the preamble etc causes problems and the small title I have in each report takes a whole page... In summary, I'm looking for a way of including a number of 1 or 2 page self-complete LaTeX files in a large report, keeping their original layouts, but changing the page numbering.

  • Get drop down selection from GridView on button press

    - by Chris Stewart
    I have an ASP.NET GridView that has four columns. The first three are typical BoundField elements bound to a DataTable. The forth is a TemplateField element that I create a DropDownList in on the OnRowCreated event for the GridView. What I'm attempting to do is walk down the data source for the GridView when a button is pressed. I really just need to get the values for columns one and four of each row. The first three columns have data as expected but the forth is displaying as empty. Is this because it wasn't a part of the DataTable originally? Is there any way to get the value for each drop down as I've described it, or will I need to rework this so each drop down list is a part of the DataTable?

  • sql server bulk copy out/postgres copy from infile

    - by Chris Curvey
    I'm starting a conversion of a system from MS SQL Server to Postgres. I have the table structures converted, and I use "bcp" to get the data out of SQL Server. ERROR: invalid byte sequence for encoding "UTF8": 0x80 HINT: This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding". CONTEXT: COPY cm_outgoing, line 200: "200 c:\temp\200.xml 2009-10-10 01:50:44.000 1900-01-01 00:00:00.000" I've already used "sed" to get rid of the NUL (0x00) entries in the file, and I can't find any instances of 0x80 in the file that I'm trying to import. Any thoughts? Is there an easier way?

  • Where can I find Python tutorials aimed at people who are already programmers?

    - by Chris R
    I'm a reasonably skilled programmer, and I'm interested in branching out into some new languages -- python, specifically -- but frankly I do NOT want to go through a tutorial that assumes I know nothing about programming. I want a tutorial -- again, preferably for python -- that assumes I'm just unfamiliar with the language itself and describes the ways I can use the language to solve problems. Does such a beast exist? I mean, other than the Python wiki?

  • Order of operations in C. ++ vs |=, which occurs first?

    - by chris
    I have the following code that I'm reading through: if( (i%2) == 0 ){ *d = ((b & 0x0F) << 4); } else{ *d++ |= (b & 0x0F); }; I'm looking specifically at the else statement and wondering in what order this occurs? I don't have a regular C compiler, so I can't test this. When we are performing *d++ |= (b & 0x0F);, what order does this occur in?

  • jquery .find to get the text in a <li>

    - by Chris
    So I have a series of 2 nested ul's. When you click on the text (which is in an a tag) in the li, my page makes that editable and adds a save button. clicking the save button needs to give me back the new text inside that li and the id of that li. The id is not a problem. I'm trying to use jQuery's .find to select that anchor tag (which is successful) but i can't seem to get the text from it. Here is an example of the first list and it's sublists. <ul class='lists'> <li class='list1'> <a class='a list' id='list1'> List 1 Name</a> <img id='savelist1id' onClick="SaveName(this.parentNode.id)" src='save.jpg'> <ul class='list1subs'> <li class='sub1'> <a class='a sub' id='sub1id'> Sub 1 Name</a> <img id='savesub1id' onClick="SaveName(this.parentNode.id)" src='save.jpg'> </li> <li class='sub3'> <a class='a sub' id='sub2id'> Sub 2 Name</a> <img id='savesub2id' onClick="SaveName(this.parentNode.id)" src='save.jpg'> </li> <li class='sub2'> <a class='a sub' id='sub3id'> Sub 3 Name</a> <img id='savesub3id' onClick="SaveName(this.parentNode.id)" src='save.jpg'> </li> </ul> </li> </ul> Here's the code for identifying which save button you clicked. function SaveName(parentid){ $('li').find('a').each(function(){ if (this.id == parentid){ alert(this.id+' '+this.text) } } }); I am wanting this.text to show me the text inside the anchor tags. Help, please?

  • Regular expression for a string containing one word but not another

    - by Chris Stahl
    I'm setting up some goals in Google Analytics and could use a little regex help. Lets say I have 4 URLs http://www.anydotcom.com/test/search.cfm?metric=blah&selector=size&value=1 http://www.anydotcom.com/test/search.cfm?metric=blah2&selector=style&value=1 http://www.anydotcom.com/test/search.cfm?metric=blah3&selector=size&value=1 http://www.anydotcom.com/test/details.cfm?metric=blah&selector=size&value=1 I want to create an expression that will identify any URL that contains the string selector=size but does NOT contain details.cfm I know that to find a string that does NOT contain another string I can use this expression: (^((?!details.cfm).)*$) But, I'm not sure how to add in the selector=size portion. Any help would be greatly appreciated!

  • Is 0x9B (155decimal) a special control character? Why is it missing from ascii tables?

    - by Chris
    Hi, I'm working on an embedded system, and i'm having dramas getting it to send a certain chunk of data across the serial port. I narrowed it down and found that if a 0x9B is present in the message, it corrupts the message. So i then look up 0x9b (155) on http://www.asciitable.com/, and it's missing! Isn't that a bizarre coincidence! Any ideas, is this a special character or something?

  • PHP to make vars and values part of array

    - by Chris
    I currently have this function to search and replace in a text file. // Input $ect = array('Visssa', 'Lisssa', 'her'); // Placeholders in the file $put = array('lname', 'fname', 'hisher'); // Replace the placeholders $oput = str_replace($put, $ct, 'tmpfile.txt'); This is not the full program but the idea is replace the values found in tmpfile.txt with the ones found in the $etc array. And it works flawlessly. But, what I need to do is get all passed vars (get/post) and then make the arrays so that the var is the value to replace and the value is the value to replace it with. So, if I sent the url http://xyz.com/?lname=tom&ogre=yes All instances of lname in the file would be replaces with tom and all instances of ogre would be replaced with yes. So somehow it just gets any/all variables passed in get/post and then the arrays showed above would cause the var to be replaced by the value in the file.

  • FLV Player Skin Custom URL

    - by Chris
    I have a flash banner ad (AS3) which uses a FLV Player component for a remove video. The Skin exports it's own SWF file for user with the video controls as I'm sure anyone familiar with Flash knows. Is there anyway to specify where this file is remotely? I have to provide 1 file to my advertiser, and do not want to have to create custom video controls for this. Is it possible to upload this swf file to a remote location and tell Flash to pull it from there? Any help would be greatly appreciated.

  • Why would I use Scala/Lift over Java/Spring?

    - by Chris J
    Hi, I know this question is a bit open but I have been looking at Scala/Lift as an alternative to Java/Spring and I am wonder what are the real advantages that Scala/Lift has over it. From my perspective and experience, Java Annotations and Spring really minimizes the amount of coding that you have to do for an application. Does Scala/Lift improve upon that?

  • Will Visual Studio 2010 support HTML 5?

    - by Chris
    Since Visual Studio 2010 is slated for release in March of 2010 and HTML 5 is now starting to be used even more widely, I would like to know if Visual Studio will ship with HTML 5 templates, standard controls and support for the more common markup? A definition for support of HTML 5 would be that any new version of Visual Studio should have similar support for code-completion, validation and markup that is currently supported for HTML 4.01 and XHTML 1.0 and 1.1. Update From the Visual Web Develolper Team Blog: HTML 5 intellisense and validation schema for Visual Studio 2008 and Visual Web Developer is for downloading. Follow the instructions posted on the page to install the new scheme. Seems like the Visual Studio Team will be supporting HTML 5 after all.

  • PHP Speed - Many Echos vs Building a String
