298,782 | <p>I have the following Python code: </p>
<pre><code>import xml.dom.minidom
import xml.parsers.expat
try:
domTree = ml.dom.minidom.parse(myXMLFileName)
except xml.parsers.expat.ExpatError, e:
return e.args[0]
</code></pre>
<p>which I am using to parse an XML file. Although it quite happily spots simple XML errors like mismatched tags, it completely ignores the DTD specified at the top of the XML file: </p>
<pre><code><?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<!DOCTYPE ServerConfig SYSTEM "ServerConfig.dtd">
</code></pre>
<p>so it doesn't notice when mandatory elements are missing, for example. How can I switch on DTD checking?</p>

298,786 | <p>I have a header </p>
<pre><code><h1>My Header</h1>
</code></pre>
<p>It has a height of <code>150px</code> and a <code>font-size</code> of say <code>1.3em;</code>
How can I make the header text vertically centered with CSS.
I would rather not wrap it in a container DIV (wrapping divs really defeat the whole CSS idea).</p>

298,788 | <p>Since Terminal appeared I've saved as ~/mySrvr.term a modified stock .term file
which opens to execute an ssh to a remote server and to modify the appearance.
I have NOT been able to save "use option key as meta" for emacs-ery; there's no slot for it
in the term file and I'm reluctant to wrestle with a keyboard dictionary file.
Am I missing something simple? How do I get option-as-meta to stick between sessions?</p>
<p>Thanks</p>

298,791 | <p>I have an IIS located on serverA</p>
<p>I have userA at locationA who has opened a content management system site, hosted on serverA.</p>
<p>One of the features of the system is that it allows the user to move a file to LocationB, all within the same network. Now when this move occurs and due to bandwidth restrictions, would this file move from LocationA to serverA to LocationB or is there a way for me to move the file from LocationA to LocationB without going through serverA, i.e using local memory on serverA</p>
<p>I am not using BITS at the moment.</p>

298,799 | <p>Somebody <strong>please</strong> tell me it is possible to recover Visual Studio source after VS crashes!</p>
<p>I have just spent 5 hours writing a new utility app, and running it with the "Save before Build" option turned on, as well as AutoRecover every 5-mins. But after VS crashed I am unabled to find anything other than an empty project folder!!! I can't believe that files are only "saved" to memory?!? That can't be right! That 5 hours of work has to be <strong>somewhere</strong> on the disk?</p>
<p>I attempted to reproduce the scenario by creating a Junk project, running it, and then killing VS using Task Manager. It wasn't quite the same situation as a dialog box actually popped up asking to save the project. I ignored this and continued the kill. I was then able to find the Junk source in C:\Users{Username}\AppData\Local\Temporary Projects as advised - but not my earlier project.</p>
<p>I think it's gone.</p>

298,812 | <p>I have two Tables.</p>
<p>Order - With Columns OrderID, OrderStatusID<br />
OrderStatus - With Columns OrderStatusID, Description</p>
<p>I have an Order Object which calls to the database and fills its properties for use in my code. Right now I have access to Order.OrderStatusID, but in my application I really need access to the "Description" field.</p>
<p>How do you handle this elegantly with good OO design?</p>

298,830 | <p>I have a single string that contains the command-line parameters to be passed to another executable and I need to extract the string[] containing the individual parameters in the same way that C# would if the commands had been specified on the command-line. The string[] will be used when executing another assemblies entry-point via reflection.</p>
<p>Is there a standard function for this? Or is there a preferred method (regex?) for splitting the parameters correctly? It must handle '"' delimited strings that may contain spaces correctly, so I can't just split on ' '.</p>
<p>Example string:</p>
<pre><code>string parameterString = @"/src:""C:\tmp\Some Folder\Sub Folder"" /users:""abcdefg@hijkl.com"" tasks:""SomeTask,Some Other Task"" -someParam foo";
</code></pre>
<p>Example result:</p>
<pre><code>string[] parameterArray = new string[] {
@"/src:C:\tmp\Some Folder\Sub Folder",
@"/users:abcdefg@hijkl.com",
@"tasks:SomeTask,Some Other Task",
@"-someParam",
@"foo"
};
</code></pre>
<p>I do not need a command-line parsing library, just a way to get the String[] that should be generated.</p>
<p><strong>Update</strong>: I had to change the expected result to match what is actually generated by C# (removed the extra "'s in the split strings)</p>

298,840 | <p>I have a .NET Web app which consumes a Java-based Web service. One of the objects, named Optional, contains search criteria fields. The schema is the following:</p>
<pre><code><xsd:complexType name="Optional">
<xsd:sequence>
<xsd:element name="FromAmount" nillable="true" type="xsd:float" minOccurs="0" />
<xsd:element name="ToAmount" nillable="true" type="xsd:float" minOccurs="0" />
<xsd:element name="FromDate" nillable="true" type="xsd:dateTime" minOccurs="0" />
<xsd:element name="ToDate" nillable="true" type="xsd:dateTime" minOccurs="0" />
<xsd:element name="FromCheckNumber" nillable="true" type="xsd:long" minOccurs="0" />
<xsd:element name="ToCheckNumber" nillable="true" type="xsd:long" minOccurs="0" />
</xsd:sequence>
</xsd:complexType>
</code></pre>
<p>The problem that I am running into is that the child elements will not serialize even when a value is assigned to them in the Web app. If I remove the minOccurs attribute, then all is well.</p>
<p>How do I get these elements to be optional, but to serialize when a value is assigned to them?</p>
<p>Thanks in advance for your help.</p>

298,841 | <p>Is there a way to read the properties inside an <a href="https://en.wikipedia.org/wiki/Windows_Installer" rel="nofollow noreferrer">MSI</a> file?</p>
<p>For example, given a MSI file named <em>Testpackage.msi</em>, I need to find</p>
<pre><code>productName
PackageCode
version
</code></pre>
<p>This I am going to use it with WMI uninstall</p>
<pre><code>string objPath = string.Format("Win32_Product.IdentifyingNumber='{0}', Name='{1}', Version='{2}'", "{AC9C1263-2BA8-4863-BE18-01232375CE42}", "testproduct", "10.0.0.0");
</code></pre>
<p>Using <a href="http://msdn.microsoft.com/en-us/library/aa370557(v=vs.85).aspx" rel="nofollow noreferrer">Orca</a> is a great option, if this can be achieved programmatically. Then I can use this to generate automatic release notes. And in un-installing program too.</p>

298,873 | <p>I'm wondering what good ways there would be make assertions about synchronization or something so that I could detect synchronization violations (while testing).</p>
<p>That would be used for example for the case that I'd have a class that is not thread-safe and that isn't going to be thread-safe. With some way I would have some assertion that would inform me (log or something) if some method(s) of it was called from multiple threads.</p>
<p>I'm longing for something similar that could be made for AWT dispatch thread with the following:</p>
<pre><code>public static void checkDispatchThread() {
if(!SwingUtilities.isEventDispatchThread()) {
throw new RuntimeException("GUI change made outside AWT dispatch thread");
}
}
</code></pre>
<p>I'd only want something more general. The problem description isn't so clear but I hope somebody has some good approaches =)</p>

298,897 | <p>I've been putting together a small web form for our technicians to use from their phones out in the field. However I'm having a lot of trouble getting things working using ASP.NET Mobile, and there seems to be few resources out there to help learn this stuff. I'm also having trouble <a href="https://stackoverflow.com/questions/291638/how-do-you-get-the-value-of-a-bound-mobilelistitem" title="Getting Help">getting help</a>. </p>
<p>So the thing is, do I really need to use the mobile controls? The phones will all have web browsers, so I'm thinking if I'm careful with the interface I can get as good or better results than using the mobile controls. </p>
<p>The only thing I would like from the mobile controls is the PhoneCall control... so the follow up question would be: Can I get the functionality of the PhoneCall control without using it?</p>

298,909 | <p>I'm wondering why the <code>assert</code> keyword is so underused in Java? I've almost never seen them used, but I think they're a great idea. I certainly much prefer the brevity of:</p>
<pre><code>assert param != null : "Param cannot be null";
</code></pre>
<p>to the verbosity of:</p>
<pre><code>if (param == null) {
throw new IllegalArgumentException("Param cannot be null");
}
</code></pre>
<p>My suspicion is that they're underused because</p>
<ul>
<li>They arrived relatively late (Java 1.4), by which time many people had already established their Java programming style/habit</li>
<li>They are turned off at runtime by default</li>
</ul>

298,962 | <p>Clearly separation of concerns is a desirable trait in our code and the first obvious step most people take is to separate data access from presentation. In my situation, LINQ To SQL is being used within data access objects for the data access.</p>
<p>My question is, where should the use of the entity object stop? To clarify, I could pass the entity objects up to the domain layer but I feel as though an entity object is more than just a data object - it's like passing a bit of the DAL up to the next layer too.</p>
<p>Let's say I have a UserDAL class, should it expose an entity User object to the domain when a method GetByID() is called, or should it spit out a plain data object purely for storing the data and nothing more? (seems like wasteful duplication in this case)</p>
<p>What have you guys done in this same situation? Is there an alternative method to this?</p>
<p>Hope that wasn't too vague.</p>
<p>Thanks a lot,</p>
<p>Martin.</p>

298,972 | <p>I am using a query like this on my postgres database:</p>
<pre><code>SELECT TableA.id FROM TableA , TableB WHERE TableA.id = 100;
</code></pre>
<p>Each TableA.id is unique (it's an autoincrement), I am getting more than 1 result. Am I missing something in here?</p>

298,976 | <p>Seeing as C# can't <code>switch</code> on a Type (which I gather wasn't added as a special case because <code>is</code> relationships mean that more than one distinct <code>case</code> might apply), is there a better way to simulate switching on type other than this?</p>
<pre><code>void Foo(object o)
{
if (o is A)
{
((A)o).Hop();
}
else if (o is B)
{
((B)o).Skip();
}
else
{
throw new ArgumentException("Unexpected type: " + o.GetType());

298,981 | <p>I'm trying to have an XSLT that copies most of the tags but removes empty "<code><b/></code>" tags. That is, it should copy as-is "<code><b> </b></code>" or "<code><b>toto</b></code>" but completely remove "<code><b/></code>".</p>
<p>I think the template would look like :</p>
<pre><code><xsl:template match="b">
<xsl:if test=".hasChildren()">
<xsl:element name="b">
<xsl:apply-templates/>
</xsl:element>
</xsl:if>
</xsl:template>
</code></pre>
<p>But of course, the "<code>hasChildren()</code>" part doesn't exist ... Any idea ?</p>

299,011 | <p>I am getting a lot of errors when starting RAD7. The server doesn't respond to class changes. Sometimes the server won't start. Sometimes RAD will not acknowledge modules that I added to the server. It is kind of buggy.</p>
<p>I know there is metadata in the workspace, are there safe ways to clean the metadata or RAD in general?</p>
<p>Where RAD = Rational Application Developer</p>

299,027 | <p>I'm not sure what this practice is actually called, so perhaps someone can edit the title to more accurately reflect my question.</p>
<p>Let's say we have a site that stores objects of different types. Each type of object has its own database (a database of books and assorted information with its tables, a database of CDs and information with its tables, and so on). However, all of the objects have keywords and the keywords should be uniform across all objects, regardless of type. A new database with a few tables is made to store keywords, however each object database is responsible for mapping the object ID to a keyword.</p>
<p>Is that a good practice?</p>

299,068 | <p>Question: Is exception handling in Java actually slow?</p>
<p>Conventional wisdom, as well as a lot of Google results, says that exceptional logic shouldn't be used for normal program flow in Java. Two reasons are usually given,</p>
<ol>
<li>it is really slow - even an order of magnitude slower than regular code (the reasons given vary), </li>
</ol>
<p>and </p>
<ol start="2">
<li>it is messy because people expect only errors to be handled in exceptional code. </li>
</ol>
<p>This question is about #1.</p>
<p>As an example, <a href="http://leepoint.net/notes-java/flow/exceptions/03exceptions.html" rel="noreferrer">this page</a> describes Java exception handling as "very slow" and relates the slowness to the creation of the exception message string - "this string is then used in creating the exception object that is thrown. This is not fast." The article <a href="http://adtmag.com/articles/2000/08/22/effective-exception-handling-in-java.aspx" rel="noreferrer">Effective Exception Handling in Java</a> says that "the reason for this is due to the object creation aspect of exception handling, which thereby makes throwing exceptions inherently slow". Another reason out there is that the stack trace generation is what slows it down.</p>
<p>My testing (using Java 1.6.0_07, Java HotSpot 10.0, on 32 bit Linux), indicates that exception handling is no slower than regular code. I tried running a method in a loop that executes some code. At the end of the method, I use a boolean to indicate whether to <em>return</em> or <em>throw</em>. This way the actual processing is the same. I tried running the methods in different orders and averaging my test times, thinking it may have been the JVM warming up. In all my tests, the throw was at least as fast as the return, if not faster (up to 3.1% faster). I am completely open to the possibility that my tests were wrong, but I haven't seen anything out there in the way of the code sample, test comparisons, or results in the last year or two that show exception handling in Java to actually be slow.</p>
<p>What leads me down this path was an API I needed to use that threw exceptions as part of normal control logic. I wanted to correct them in their usage, but now I may not be able to. Will I instead have to praise them on their forward thinking?</p>
<p>In the paper <a href="http://portal.acm.org/citation.cfm?id=337453" rel="noreferrer">Efficient Java exception handling in just-in-time compilation</a>, the authors suggest that the presence of exception handlers alone, even if no exceptions are thrown, is enough to prevent the JIT compiler from optimizing the code properly, thus slowing it down. I haven't tested this theory yet.</p>

299,095 | <p>Is there a way to turn off the automatic selection of the first row in the built-in DataGrid in Silverlight?</p>
<p>We build a lot of functionality based off the user selecting a row in a data grid. The automatic firing of SelectionChanged when databinding or sorting is really causing us issues. We have tried to put some guards around the selection, but can't seem get all problems covered.</p>
<p>For example, if you have DataGrid in a tab of a TabControl that is not shown when loading the screen and the DataGrid has a binding to a property of the DataContext that is a list of objects. The grid is not databound until the tab is shown. Is there an event telling us that the grid is databinding? Shouldn't the default behavior of databinding be not to select a row?</p>
<p>Thanks
Mike</p>

299,097 | <p>I'm currently monitoring a large network with Hobbit and have been tasked with lowering the amount of false (or at least irrelevant) alarms. At the top of my list are the tests "http" and "conn", initiated by bbtest-net. This command checks ping, ssh, etc, and if for instance a ping times out, it immediately sets the status to red. One minute later, the bbretest command kicks in, checks all the newly reddened hosts, and finds it to be green again. This happens <strong>all the time</strong>, and it clutters up my log. </p>
<p>Is there any way for me to make Hobbit report a red status AFTER bbretest has been run the first time? </p>

299,106 | <p>I have a following xslt code :</p>
<pre><code><xsl:template match="table_terms_and_abbr">
<informaltable frame='none' colsep='none' rowsep='none'>
<tgroup cols='2' align='left'>
<colspec colnum="1" colwidth='1*'/>
<colspec colnum="2" colwidth='1*'/>
<xsl:apply-templates/>
</tgroup>
</informaltable>
</xsl:template>
</code></pre>
<p>and the following xml that it's processing : </p>
<pre><code><table_terms_and_abbr>
<tblrow_hdr>Name ,, Description</tblrow_hdr>
<tbody>
<tblrow_bold_first> BOT ,, &j_bot;</tblrow_bold_first>
...
</tbody>
</table_terms_and_abbr>
</code></pre>
<p>Now i want to improve the xslt by moving following lines inside the <code>table_terms_and_abbr</code>:</p>
<pre><code><tblrow_hdr>Name ,, Description</tblrow_hdr>
<tbody>
</tbody>
</code></pre>
<p>So i will have something like : </p>
<pre><code><xsl:template match="table_terms_and_abbr">
<informaltable frame='none' colsep='none' rowsep='none'>
<tgroup cols='2' align='left'>
<colspec colnum="1" colwidth='1*'/>
<colspec colnum="2" colwidth='1*'/>
<xsl:call-template name="tblrow_hdr">
BOT ,, &j_bot; * ???? *
</xsl:call-template>
<tbody>
<xsl:apply-templates/>
</tbody>
</tgroup>
</informaltable>
</xsl:template>
</code></pre>
<p>The line marked with * ???? * does not work. I using saxon9 (xslt 2.0 stylesheet) on linux platform and got this error: </p>
<p><em>XTSE0010: No character data is allowed within xsl:call-template</em></p>
<p>I know how to pass the attributes to the template i.e: </p>
<pre><code><xsl:with-param name="is_make_first_bold" select = "1" as="xs:integer"/>
</code></pre>
<p>but how to pass free text ? </p>
<p>The idea is move to the template all static data and in xml only use variable data i.e </p>
<pre><code><table_terms_and_abbr>
<tblrow_bold_first> BOT ,, &j_bot;</tblrow_bold_first>
...
</table_terms_and_abbr>
</code></pre>
<p><strong>More Info</strong><br>
My requirement was to create a simplified syntax for defining repeatable tables for our DocBook documentation. For that i created a general named template <code>tblrow</code> that will split the line delimited by ",," to separate entities and will create a list of entries in the table row.<br>
Each entry can be a simple string, an ENTITY or another template.
Since the parameter numbers are undefined (the tables can have different number of cells) i can't use a standard parameters for the templates and used delimited string. If i want to have one of the table entries to contain a link to some place in the document i can't use the parameters again since i can't pass xref template as a parameter.<br>
The main reason not to change the <code>tblrow</code> template is that it's working :) and it's kind of complex. It's took me ages to achieve this and I'm not completely understand how it's working :). </p>
<p>Now on top of this i have a few variables that can control the displayed output like <code>tblrow_hdr</code> that will underline and bold the text in each entry. Since <code>tblrow_hdr</code> is common for all <code>table_terms_and_abbr</code> tables it just sounds logical to me not having this in xml rather put the call to the <code>tblrow_hdr</code> inside the <code>table_terms_and_abbr</code> template and here i stuck. </p>

299,128 | <p>Is there an easy way to chase down table/stored procedure/function dependencies in SQL Server 2005+? I've inherited a giant application with lots of tables and even more stored procedures and functions that are long and interlinked. </p>
<p>At the end of the day is there a way to build a dependency tree? Ideally what I'm looking for goes in both directions:</p>
<p><strong>For a table/procedure - what depends ON it?</strong>: Show me all the stored procedures that eventually reference it (ideally in a tree view such that sub procedures nest out to the bigger procedures that call them)</p>
<p><strong>For a procedure - what does IT depend on?</strong>: Show me all the procedures and tables that a given procedure will (or could) touch when running.</p>
<p>It seems this tool shouldn't be that hard to make and would be incredibly useful for DB maintenance generally. Is anyone aware of such a thing? If this doesn't exist, why the heck not?</p>
<p>The built-in functionality in Management Studio is nice but the information does not appear to be complete at all.</p>

299,142 | <p>I've been reading up on branching/merging with Subversion 1.5 using the excellent and free <a href="http://svnbook.red-bean.com/" rel="noreferrer">Version Control with Subversion</a> book. I think that I understand how to use the Subversion command line client to perform the actions that I need most often, which are:</p>
<p><strong>Update Branch with Changes from Trunk</strong></p>
<p>From the branch's working directory run: </p>
<blockquote>
<p>svn merge <a href="http://svn.myurl.com/proj/trunk" rel="noreferrer">http://svn.myurl.com/proj/trunk</a></p>
</blockquote>
<p><strong>Merge Branch into Trunk</strong></p>
<p>From the trunk's working directory run:</p>
<blockquote>
<p>svn merge --reintegrate <a href="http://svn.myurl.com/proj/branches/mybranch" rel="noreferrer">http://svn.myurl.com/proj/branches/mybranch</a></p>
</blockquote>
<p>However, we are using TortoiseSVN 1.5 as our interface to Subversion. I would like to know how best to perform these operations with TortoiseSVN. The new dialog provides three different options on the main menu. </p>
<ol>
<li>Merge a range of revisions</li>
<li>Reintegrate a branch</li>
<li>Merge two different trees</li>
</ol>
<p>From what I can gather, TortoiseSVN always executes svn with the following syntax.</p>
<blockquote>
<p>svn merge [--dry-run] --force From_URL@revN To_URL@revM PATH</p>
</blockquote>
<p>Additionally, reintegrate a branch often fails with a message stating that some targets have not been merged and so it cannot continue, and so I had to use option #3.</p>
<p>My questions are:</p>
<ol>
<li>How do I use TortoiseSVN 1.5 to merge changes from the trunk to a branch?</li>
<li>How do I use TortoiseSVN 1.5 to merge the branch to the trunk, with and without the reintegrate method?</li>
<li>Which of the above options should I use for each, and why?</li>
</ol>
<hr>
<p><strong>EDIT</strong></p>
<p>Through "dry run" testing I have found that the command line Subversion operation</p>
<blockquote>
<p>svn merge <a href="http://svn.myurl.com/proj/trunk" rel="noreferrer">http://svn.myurl.com/proj/trunk</a></p>
</blockquote>
<p>is analogous to option #1 (Merge a Range of Revisions) in TortoiseSVN, as long as I leave the revision range blank.</p>

<p>Here is my Post function (it is enclosed in the <code>$(document).ready(function() {...</code></p>
<p>The alert in the response function never fires:</p>
<pre><code> $('.nextButton').click(function() {
var idString = '';
$("div.dropZone > div").each(function(n) {
idString += this.id + '|';
});
$.post('CustomPostHandler.aspx?step=criteria', {
selected: idString
},
function(data) {
alert(data);
});
});
</code></pre>
<p>The post handler page does receive the idString variable fine, after some processing it attempts to write back a response:</p>
<pre><code> // Return dummy response to caller
Response.Clear();
Response.ContentType = "text/plain";
Response.Write("success");
Response.End();
</code></pre>
<p>I've checked the deployment server environment and don't see anything missing (this is running against the 3.5 SP1 framework). Anyone have any ideas or am I missing something?</p>

299,176 | <p>I've been running into some problems duplicating some old ASP files into some newer .NET 2.0 code. One of the tasks is to merge the 4-5 SQL statements into one. While I have done this and had some success in performance boosts, Oracle is a new bag for me. This problem however surpasses my own SQL skills as I haven't done this before.</p>
<p>Basically, I have a QUANTITY in one table from a bunch of Sales. Each sale has an integer value. Each sale also has an ITEM attached to it. Each ITEM has a CONVERSION factor as in if I sell 1 bag of something = 10 bundles of something. So, when I run a report and want to find out the end value, I need to take each sale and its quantity and multiple it by its conversion factor. Most are simple 1 to 1, so it's basically doing 25 * 1, 30 * 1 etc.</p>
<p>My problem is that there are past sales in my records in which the ITEM has been removed from our system, therefore the CONVERSION factor does not exist. Those records get dropped from my query because the FACTOR is gone.</p>
<pre><code>SELECT rth.CODE, rth.NUMBER, rth.QUANTITY, rth.sale_code
FROM salesdetails rth, salesheader rsh
WHERE rsh.number = rth.number(+)
AND rsh.customer_code = '05'
AND rsh.r_code = '01'
AND rsh.location_code = '12'
AND rth.sale_code IN('ITEM07')
AND rth.c_code = 'WLMT'
AND rsh.year = '2008'
</code></pre>
<p>This is my first QUERY. If I add the conversion in:</p>
<pre><code>SELECT rth.CODE, rth.NUMBER, rth.QUANTITY, rth.sale_code, rth.quantity * cf.conversion
FROM salesdetails rth, salesheader rsh, conversionfactor cf
WHERE rsh.number = rth.number(+)
AND rsh.customer_code = '05'
AND rsh.r_code = '01'
AND rsh.location_code = '12'
AND rth.sale_code IN('ITEM07')
AND rth.c_code = 'WLMT'
AND rsh.year = '2008'
AND cf.item_code = rth.item_code
and cf.code = '01'
and cf.loc_code = '00001'
</code></pre>
<p>This works to an extent. It lists all the same records, but it is missing any records in which the CONVERSION factor did not exist. Is there anyway I can still include those records where the FACTOR didn't exist in the second query, short from going line by line and doing the conversion that way.</p>

299,198 | <p>I am looking for good ideas for implementing a generic way to have a single line (or anonymous delegate) of code execute with a timeout.</p>
<pre><code>TemperamentalClass tc = new TemperamentalClass();
tc.DoSomething(); // normally runs in 30 sec. Want to error at 1 min
</code></pre>
<p>I'm looking for a solution that can elegantly be implemented in many places where my code interacts with temperamental code (that I can't change).</p>
<p>In addition, I would like to have the offending "timed out" code stopped from executing further if possible.</p>

299,200 | <p>Topic: Programmatically manipulate web browser in OS X 10.4.x+ Tiger/Leopard.
Subjects: Webkit, Safari, Firefox, APIs, Applescript, Automator, Javascript, Ruby, Ruby on Rails, OS X, Tiger
Goal: Collect/Read/Extract URLs from Safari into text (Ruby on Rails code) file.
Note: A solution that uses FF would be very appreciated, too. I use Safari (v. 3.x, OS X 10.4.x) more and much prefer a solution that works in Safari.</p>
<p>At times, I use the web browser to find/display multiple site pages that I 1) want to visit again later and 2) the URLs of which I want to group together in a text file for a) future reference and/or b) programmatically manipulate.</p>
<p>For example: In today's NYT I find seven NYT articles I want to post to my del.icio.us acct. and share via email in their "printer friendly" format long after they are headlined in that day's online edition. I open each one in a browser window's tap, then Presto! their URLs automagically are wooshed into a file where a (custom) Ruby on Rails app sends the print versions' URLs to email addresses and my Del.icio.us acct.</p>
<p>I figure there's a way to do the URL extracting step from the OS using Applescript or Automator. I figure there MAY be a way to do it with Javascript.</p>
<p>My Question: How to read the web browser's tabs' location field and collate these strings into a text file (either within my OS or over the wire to a web app.)?</p>
<p>Much appreciated.</p>

299,209 | <p>i'm a long-time newbie to c#, and this question may be too obvious, so please forgive if i'm "doing it wrong."</p>
<p>Using Visual Studio 2005 Pro, C#, SQL Server 2000 EE SP3.</p>
<p>I have a stored proc that takes one input param and returns several output params pertaining to that input. I am also calling it successfully, and String.Format-ing the outputs into a RichTextBox. I'd like to call this proc periodically and each time stick the output params into a DataGridView row, so the results accumulate over time.</p>
<ul>
<li>What's the simplest/most elegant way to do get those parameters into the DataGridView? I'd prefer code instead of some GUI builder solution.</li>
<li>Am i overlooking some better approach, such as a more appropriate control?</li>
</ul>
<p>Thanks!</p>

299,249 | <p>I am familiar with using the <em>os.system</em> to run from the command line. However, I would like to be able to run a jar file from inside of a specific folder, eg. my 'test' folder. This is because my jar (located in my 'test' folder) requires a file inside of my 'test' folder. So, how would I write a function in my script that does the following: <code>c:\test>java -jar run_this.jar required_parameter.ext</code> ? I'm a python newbie so details are greatly appreciated. Thanks in advance. </p>

299,251 | <p>I am attempting to write a component in C# to be consumed by classic ASP that allows me to access the indexer of the component (aka default property).</p>
<p>For example:<br>
C# component:</p>
<pre><code>public class MyCollection {
public string this[string key] {
get { /* return the value associated with key */ }
}
public void Add(string key, string value) {
/* add a new element */
}
}
</code></pre>
<p>ASP consumer:</p>
<pre><code>Dim collection
Set collection = Server.CreateObject("MyCollection ")
Call collection.Add("key", "value")
Response.Write(collection("key")) ' should print "value"
</code></pre>
<p>Is there an attribute I need to set, do I need to implement an interface or do I need to do something else? Or this not possible via COM Interop?</p>
<p>The purpose is that I am attempting to create test doubles for some of the built-in ASP objects such as Request, which make use of collections using these default properties (such as <code>Request.QueryString("key")</code>). Alternative suggestions are welcome.</p>
<p>Update: I asked a follow-up question: <a href="https://stackoverflow.com/questions/317759/why-is-the-indexer-on-my-net-component-not-always-accessible-from-vbscript">Why is the indexer on my .NET component not always accessible from VBScript?</a></p>

299,254 | <p>In essence I'd like to store some rows in a temporary variable for the life of a procedure in MySQL.</p>
<p>My procedure will grab a column of foreign keys at the beginning of the procedure. Once I'm done working with them I want to update the table to indicate that they have been processed. There may be inserts into this table while my procedure is working on it's set of data so I don't want to erroneously mark these new rows as processed. I also do not want to lock this table and hold up the thread that is making the inserts. </p>
<p>Is a temporary table the best solution?</p>

299,255 | <p>I'm starting to try and test my Doctrine objects with PHPUnit, and would like to reload the DB from my model objects afresh each time.</p>
<p>My first attempt looks something like this:</p>
<pre><code>class Tests_User extends PHPUnit_Framework_TestCase
{
public function setUp()
{
Doctrine_Manager::connection('mysql://user:pass@localhost/testdb');
Doctrine::createDatabases();
Doctrine::createTablesFromModels('../../application/models');
}
public function testSavingWorks()
{
$user = new User();
$user->save();
}
public function testSavingWorksAgain()
{
$user = new User();
$user->save();
}
public function tearDown()
{
Doctrine::dropDatabases();
}
}
</code></pre>
<p>The problem is that when setUp() is called again for the second test, createTablesFromModels() fails, so I get an error because none of the tables are present.</p>
<p>I'd really appreciate an example of how someone else has reinitialised a Doctrine connection for PHPUnit or other unit testing purposes.</p>

299,267 | <p>What is the best way to scale a 2D image array? For instance, suppose I have an image of 1024 x 2048 bytes, with each byte being a pixel. Each pixel is a grayscale level from 0 to 255. I would like to be able to scale this image by an arbitrary factor and get a new image. So, if I scale the image by a factor of 0.68, I should get a new image of size 0.68*1024 x 0.68*2048. some pixels will be collapsed onto each other. And, if I scale by a factor of say 3.15, I would get a larger image with pixels being duplicated. So, what's the best way to accomplish this?</p>
<p>Next, I would like to be able to rotate an image by an arbitrary angle, in the range of 0 to 360 degrees (0 - 2Pi). Cropping of the image after rotating isn't an issue. What would be the best way to do this?</p>

299,291 | <p>Does anyone know if its possible to create a new property on an existing Entity Type which is based on 2 other properties concatenated together?</p>
<p>E.g. My Person Entity Type has these fields "ID", "Forename", "Surname", "DOB"</p>
<p>I want to create a new field called "Fullname" which is </p>
<pre><code>Forenames + " " + Surname
</code></pre>
<p>So i end up with "ID", "Forename", "Surname", "DOB", "Fullname".</p>
<p>I know i can do this using Linq programmatically i.e.</p>
<pre><code>var results = from p in db.People
select new {
ID = p.ID,
Forename = p.Forename,
Surname = p.Surname,
DOB = p.DOB,
Fullname = p.Forename+ " " + p.Surname
};
</code></pre>
<p>Then calling something like</p>
<pre><code>var resultsAfterConcat = from q in results
where q.Fullname.Contains(value)
select q;
</code></pre>
<p>However i'd really like to use Linq to Entities to do this work for me at the Conceptual Model level.</p>

299,296 | <p>Since yesterday, I am analyzing one of our project with <a href="http://www.ndepend.com/" rel="nofollow noreferrer">Ndepend</a> (free for most of its features) and more I am using it, and more I have doubt about the real value of this type of software (code-analysis software).</p>
<p>Let me explain, The system build a report about the health of the system and class by Rank every metric. I thought it would be a good starting point to do modifications but most of the top result are here because they have over 100 lines inside the class (we have big headers and we do use VS comments styles) so it's not a big deal... than the number of Afferent Coupling level (CA) is always too high and this is almost very true for Interface that we used a lot... so at this moment I do not see something wrong but NDepend seem to do not like it (if you have suggestion to improve that tell me because I do not see the need for). It's the samething for the metric called "NOC" for Number of children that most of my Interface are too high...</p>
<p>For the moment, the only very useful metric is the Cyclomatic Complexity...</p>
<p><strong>My question is</strong> : Do you find is worth it to analyse code with Automatic Code Analyser like NDepend? If yes, how do you filter all information that I have mentionned that doesn't really show the real health of the system?</p>

299,304 | <p>Per the Java documentation, the <a href="http://java.sun.com/javase/6/docs/api/java/lang/String.html#hashCode()" rel="noreferrer">hash code</a> for a <code>String</code> object is computed as:</p>
<blockquote>
<pre><code>s[0]*31^(n-1) + s[1]*31^(n-2) + ... + s[n-1]

<p>using <code>int</code> arithmetic, where <code>s[i]</code> is the

<p>Why is 31 used as a multiplier?</p>
<p>I understand that the multiplier should be a relatively large prime number. So why not 29, or 37, or even 97?</p>

299,370 | <p>I'm trying to use <code>SetWindowsHookEx</code> to set up a <code>WH_SHELL</code> hook to get notified of system-wide <code>HSHELL_WINDOWCREATED</code> and <code>HSHELL_WINDOWDESTROYED</code> events. I pass 0 for the final <code>dwThreadId</code> argument which, according to <a href="http://msdn.microsoft.com/en-us/library/ms644990(VS.85).aspx" rel="noreferrer">the docs</a>, should "associate the hook procedure with all existing threads running in the same desktop as the calling thread". I also pass in the handle to my DLL (<code>HInstance</code> in Delphi) for the <code>hMod</code> parameter as did all the examples I looked at.</p>
<p>Yet, I only ever get notified of windows created by my own app and - more often than not - my tests result in the desktop process going down in flames once I close down my app. Before you ask, I do call <code>UnhookWindowsHookEx</code>. I also always call <code>CallNextHookEx</code> from within my handler.</p>
<p>I am running my test app from a limited user account but so far I haven't found any hints indicating that this would play a role... (though that actually surprises me)</p>
<p>AFAICT, I did everything by the book (obviously I didn't but so far I fail to see where).</p>
<p>I'm using Delphi (2007) but that shouldn't really matter I think.</p>
<p><strong>EDIT:</strong> Maybe I should have mentioned this before: I did download and try a couple of examples (though there are unfortunately not that many available for Delphi - especially none for <code>WH_SHELL</code> or <code>WH_CBT</code>). While they do not crash the system like my test app does, they still do not capture events from other processes (even though I can verify with ProcessExplorer that they get loaded into them alright). So it seems there is either something wrong with my system configuration or the examples are wrong or it is simply not possible to capture events from other processes. Can anyone enlighten me?</p>
<p><strong>EDIT2:</strong> OK, here's the source of my test project.</p>
<p>The DLL containing the hook procedure:</p>
<pre><code>library HookHelper;
uses
Windows;
{$R *.res}
type
THookCallback = procedure(ACode, AWParam, ALParam: Integer); stdcall;
var
WndHookCallback: THookCallback;
Hook: HHook;
function HookProc(ACode, AWParam, ALParam: Integer): Integer; stdcall;
begin
Result := CallNextHookEx(Hook, ACode, AWParam, ALParam);
if ACode < 0 then Exit;
try
if Assigned(WndHookCallback)
// and (ACode in [HSHELL_WINDOWCREATED, HSHELL_WINDOWDESTROYED]) then
and (ACode in [HCBT_CREATEWND, HCBT_DESTROYWND]) then
WndHookCallback(ACode, AWParam, ALParam);
except
// plop!
end;
end;
procedure InitHook(ACallback: THookCallback); register;
begin
// Hook := SetWindowsHookEx(WH_SHELL, @HookProc, HInstance, 0);
Hook := SetWindowsHookEx(WH_CBT, @HookProc, HInstance, 0);
if Hook = 0 then
begin
// ShowMessage(SysErrorMessage(GetLastError));
end
else
begin
WndHookCallback := ACallback;
end;
end;
procedure UninitHook; register;
begin
if Hook <> 0 then
UnhookWindowsHookEx(Hook);
WndHookCallback := nil;
end;
exports
InitHook,
UninitHook;
begin
end.
</code></pre>
<p>And the main form of the app using the hook:</p>
<pre><code>unit MainFo;
interface
uses
Windows, SysUtils, Forms, Dialogs, Classes, Controls, Buttons, StdCtrls;
type
THookTest_Fo = class(TForm)
Hook_Btn: TSpeedButton;
Output_Lbx: TListBox;
Test_Btn: TButton;
procedure Hook_BtnClick(Sender: TObject);
procedure Test_BtnClick(Sender: TObject);
public
destructor Destroy; override;
end;
var
HookTest_Fo: THookTest_Fo;
implementation
{$R *.dfm}
type
THookCallback = procedure(ACode, AWParam, ALParam: Integer); stdcall;
procedure InitHook(const ACallback: THookCallback); register; external 'HookHelper.dll';
procedure UninitHook; register; external 'HookHelper.dll';
procedure HookCallback(ACode, AWParam, ALParam: Integer); stdcall;
begin
if Assigned(HookTest_Fo) then
case ACode of
// HSHELL_WINDOWCREATED:
HCBT_CREATEWND:
HookTest_Fo.Output_Lbx.Items.Add('created handle #' + IntToStr(AWParam));
// HSHELL_WINDOWDESTROYED:
HCBT_DESTROYWND:
HookTest_Fo.Output_Lbx.Items.Add('destroyed handle #' + IntToStr(AWParam));
else
HookTest_Fo.Output_Lbx.Items.Add(Format('code: %d, WParam: $%x, LParam: $%x', [ACode, AWParam, ALParam]));
end;
end;
procedure THookTest_Fo.Test_BtnClick(Sender: TObject);
begin
ShowMessage('Boo!');
end;
destructor THookTest_Fo.Destroy;
begin
UninitHook; // just to make sure
inherited;
end;
procedure THookTest_Fo.Hook_BtnClick(Sender: TObject);
begin
if Hook_Btn.Down then
InitHook(HookCallback)
else
UninitHook;
end;
end.

299,382 | <p>I am looking for example code that provides a unit test to serialize and deserialize an object from a memory stream. I have found <a href="https://stackoverflow.com/questions/236599/how-to-unit-test-if-my-object-is-really-serializablable">examples using C# 2.0</a>, however my current project uses VB.NET 1.1 (don't ask me why...), so the solution can not use generics. I am also using the NUnit framework for the unit tests.</p>
<p>Thanks!</p>

299,390 | <p>Say I have the following Objective-C class:</p>
<pre><code>@interface Foo {
int someNumber;
NSString *someString;
}
</code></pre>
<p>and for reasons I won't get into here, I want to use KVC to update, in a generic fashion, the values for those variables:</p>
<pre><code>[f setValue:object forKey:@"someNumber"];
or
[f setValue:object forKey:@"someString"];`
</code></pre>
<p>If <code>object</code> is a string and I'm updating the <code>someNumber</code> variable, it seems that I need to know to use an NSNumberFormatter to get an NSNumber and then Cocoa automatically converts that to an int inside <code>setValue:forKey:</code>. </p>
<p>Is there any way to avoid this custom code and have Cocoa infer the conversion to an int from a string, or do I need to catch this situation each time and handle it myself?</p>

<p>I tried to use sshfs to mount the remote file system on my local machine, but it is not as user friendly as simply launching a GUI, plus it seems to require root access on the client machine, which is not very convenient.</p>
<p>Of course command-line tools such as scp are possible, but I am looking for a simple GUI.</p>

299,414 | <p>I have several aspx pages that can be opened either normally (full screen in browser), or called from another page as a popup (I am using Greybox, fwiw)</p>
<p>If the page is opened as a popup in Greybox, I would like to NOT display the master page content (which displays common top and left menus, etc).</p>
<p>As far as I know, there is no way of knowing server side if the page is a popup, this must be detected in client side javascript (in the case of Greybox, by checking window.parent.parent), and therefore the master page content must be hidden via javascript as well.</p>
<p>Any ideas on how to approach this?</p>

299,416 | <p>I'm working with a existing database and trying to write a sql query to get out all the account information including permission levels. This is for a security audit. We want to dump all of this information out in a readible fashion to make it easy to compare. My problem is that there is a bridge/link table for the permissions so there are multiple records per user. I want to get back results with all the permission for one user on one line. Here is an example:</p>
<pre><code>Table_User:
UserId UserName
1 John
2 Joe
3 James
Table_UserPermissions:
UserId PermissionId Rights
1 10 1
1 11 2
1 12 3
2 11 2
2 12 3
3 10 2
</code></pre>
<p>PermissionID links to a table with the name of the Permission and what it does. Right is like 1 = view, 2 = modify, and etc.</p>
<p>What I get back from a basic query for User 1 is:</p>
<pre><code>UserId UserName PermissionId Rights
1 John 10 1
1 John 11 2
1 John 12 3
</code></pre>
<p>What I would like something like this:</p>
<pre><code>UserId UserName Permission1 Rights1 Permission2 Right2 Permission3 Right3
1 John 10 1 11 2 12 3
</code></pre>
<p>Ideally I would like this for all users.
The closest thing I've found is the Pivot function in SQL Server 2005.

The problem with this from what I can tell is that I need to name each column for each user and I'm not sure how to get the rights level. With real data I have about 130 users and 40 different permissions.</p>
<p>Is there another way with just sql that I can do this?</p>

<p>I marked the class with [DataContract()] and each member with [DataMember].</p>
<p>Why is my constructor not visible? Is there a special [attribute] for constructors?</p>

299,446 | <p>I have a function that resembles the one below. I'm not sure how to use the os module to get back to my original working directory at the conclusion of the jar's execution. </p>
<pre><code>def run():
owd = os.getcwd()
#first change dir to build_dir path
os.chdir(testDir)
#run jar from test directory
os.system(cmd)
#change dir back to original working directory (owd)
</code></pre>
<p>note: I think my code formatting is off - not sure why. My apologies in advance</p>

299,490 | <p>I need to query Active Directory for a list of users whose password is about to expire. The obvious (and easy) way to do this is with:</p>
<pre><code>dsquery user -stalepwd n
</code></pre>
<p>The problem is that I need to add additional filters to only look for users who are in certain security groups. This is hard to do with the "dsquery user" syntax that has the built-in -stalepwd option, so I've been using the "dsquery * -filter" option which allows you to use LDAP query syntax. Unfortunately, while its relatively easy to do apply the other filters with an LDAP query, I'm having trouble filtering users who have a password age greater than n.</p>
<p>Does anyone know the syntax (or if it is even possible) to filter for old passwords using the "dsquery * -filter" method instead of the "dsquery user -stalepwd" method.</p>

299,495 | <p>I have a <a href="http://download.oracle.com/javase/1.4.2/docs/api/javax/swing/JPanel.html" rel="noreferrer">JPanel</a> to which I'd like to add JPEG and PNG images that I generate on the fly.</p>
<p>All the examples I've seen so far in the <a href="http://java.sun.com/docs/books/tutorial/uiswing/" rel="noreferrer">Swing Tutorials</a>, specially in the <a href="http://java.sun.com/docs/books/tutorial/uiswing/examples/components/" rel="noreferrer">Swing examples</a> use <code>ImageIcon</code>s.</p>
<p>I'm generating these images as byte arrays, and they are usually larger than the common icon they use in the examples, at 640x480.</p>
<ol>
<li>Is there any (performance or other) problem in using the ImageIcon class to display an image that size in a JPanel?</li>
<li>What's the <em>usual</em> way of doing it?</li>
<li>How to add an image to a JPanel without using the ImageIcon class?</li>
</ol>
<p><strong>Edit</strong>: A more careful examination of the tutorials and the API shows that you cannot add an ImageIcon directly to a JPanel. Instead, they achieve the same effect by setting the image as an icon of a JLabel. This just doesn't feel right...</p>

void Error();
[DispId(0x60020001)]
void Success();
}
//Interface for public properties/methods
public interface ICardReaderProperties

//JavaScript to handle events

299,515 | <p>In C# is there a technique using reflection to determine if a method has been added to a class as an extension method?</p>
<p>Given an extension method such as the one shown below is it possible to determine that Reverse() has been added to the string class?</p>
<pre><code>public static class StringExtensions
{
public static string Reverse(this string value)
{
char[] cArray = value.ToCharArray();
Array.Reverse(cArray);
return new string(cArray);
}
}
</code></pre>
<p>We're looking for a mechanism to determine in unit testing that the extension method was appropriately added by the developer. One reason to attempt this is that it is possible that a similar method would be added to the actual class by the developer and, if it was, the compiler will pick that method up.</p>

299,529 | <p>I'm using Apache JMeter 2.3, which now supports "attempt HTTPS spoofing" under the Proxy Server element. </p>
<p>I've tried this on several different servers, and have had no success.
Has anyone been able to successfully record from an HTTPS source with this setting?</p>
<p>Or barring successfully recording, can anyone share a work-around? When available, I simply have HTTPS turned off at the server level, but this is not always feasible. Thoughts?</p>

299,536 | <p>Is it possible to create an integer (or DataTime, etc) column in ListView? It is quite important, because I would like to properly sort the list according to this column.</p>
<p>The only way to add subItems to a ListViewItem I found are:</p>
<pre><code>listviewitem.SubItems.Add("1");
</code></pre>
<p>I would like to avoid parsing these strings to get the int representation for every sort!</p>

299,553 | <p>I'm using .NET 2.0, and a recent code change has invalidated my previous Assert.AreEqual call (which compared two strings of XML). Only one element of the XML is actually different in the new codebase, so my hope is that a comparison of all the other elements will give me the result I want. The comparison needs to be done programmatically, since it's part of a unit test.</p>
<p>At first, I was considering using a couple instances of XmlDocument. But then I found this:
<a href="http://drowningintechnicaldebt.com/blogs/scottroycraft/archive/2007/05/06/comparing-xml-files.aspx" rel="nofollow noreferrer">http://drowningintechnicaldebt.com/blogs/scottroycraft/archive/2007/05/06/comparing-xml-files.aspx</a></p>
<p>It looks like it might work, but I was interested in Stack Overflow feedback in case there's a better way.</p>
<p>I'd like to avoid adding another dependency for this if at all possible.</p>

299,585 | <p>The net is overflowing with explanations of the <a href="http://en.wikipedia.org/wiki/Diamond_problem" rel="nofollow noreferrer">"dreaded diamond problem"</a>.
So is StackOverflow. I think I understand that bit, but I fail to translate that knowledge into comprehending something similar yet different.</p>
<p>My question begins as a pure C++ question, but the answer might well branch over into MS-COM specifics. The general problem question goes:</p>
<pre><code>class Base { /* pure virtual stuff */ };
class Der1 : Base /* Non-virtual! */ { /* pure virtual stuff */ };
class Der2 : Base /* Non-virtual! */ { /* pure virtual stuff */ };
class Join : virtual Der1, virtual Der2 { /* implementation stuff */ };
class Join2 : Join { /* more implementation stuff + overides */ };
</code></pre>
<p>This is <em>not</em> the classic diamond solution. Exactly what does "virtual" do here?</p>
<p>My real problem is trying to understand a <a href="http://www.codeproject.com/KB/COM/flashcontrol.aspx?fid=915540&select=2784823&tid=2774438" rel="nofollow noreferrer">discussion over at our friends' place at CodeProject.</a> It involves a custom class for creating a transparent container for the Flash player.</p>
<p>I thought I would try this place for fun. It turns out that the following declaration crashes your app, with version 10 of the Flash player.</p>
<pre><code>class FlashContainerWnd: virtual public IOleClientSite,
virtual public IOleInPlaceSiteWindowless,
virtual public IOleInPlaceFrame,
virtual public IStorage
</code></pre>
<p>Debugging shows that when entering the function implementations (QueryInterface etc), from different callers, I get different "this"-pointer values for different calls.
But <strong>removing "virtual" does the trick!</strong> No crashes, and same "this"-pointer.</p>
<p>I would like to clearly understand exactly what is going on. Thanks a lot.</p>
<p>Cheers
Adam</p>

299,597 | <p>To implement data access code in our application we need some framework to wrap around jdbc (ORM is not our choice, because of scalability).</p>
<p>The coolest framework I used to work with is <a href="http://static.springframework.org/spring/docs/2.5.x/reference/jdbc.html" rel="noreferrer">Spring-Jdbc</a>. However, the policy of my company is to avoid external dependencies, especially spring, J2EE, etc.
So we are thinking about writing own handy-made jdbc framework, with functionality similar Spring-jdbc: row mapping, error handling, supporting features of java5, but without transaction support.</p>
<p>Does anyone have experience of writing such jdbc wrapper framework?
If anyone has experience of using other jdbc wrapper frameworks, please share your experience.</p>
<p>Thanks in advance.</p>

299,604 | <p>My current project involves deploying an upgraded .exe file that runs as a Windows Service. In order to overwrite the existing .exe with the new version, I currently need to:</p>
<ol>
<li>Stop the service</li>
<li>Uninstall the service</li>
<li>Reboot the system (so Windows releases it's hold on the file)</li>
<li>Deploy the new .exe</li>
<li>Reinstall the service</li>
<li>Start the upgraded service.</li>
</ol>
<p>I'd like to avoid the reboot, so that this can be a fully scripted/automated upgrade.</p>
<p>Is there any way to avoid rebooting? Maybe a command-line tool that will force Windows to give up it's death grip on the old .exe?</p>

299,608 | <p>In addition to informing the user, we want to collect information for our debugging purposes. Our system is a niche system for only about 1400 customers, and therefore we are not as well-financed as we would hope, so bugs are more common than we would like. We currently have a window that shows the first line of the error message in larger print with a yellow background to draw the user's eye, with the scary part in a textbox below it with a gray background. There is also a button that will put all of it in the copy buffer for sending to customer support. The message that we're trying to go to consists of the exception.Message, the last five parts of the stack trace, and the name of the method that caused the error (Reflection.MethodBase). We are planning to add the ability for the user to say what he was doing at the time, and maybe a radio button indicating how often this happens, and write it to a log file. What other other useful information should we include? </p>
<p>We are also considering emailing it to customer support but not stressing if the email fails. There are other considerations with the email - customer support might drown in it, users might object because we'd be sending system info as well, etc.</p>
<p>I found two similar questions on SO, but they aren't really focussed on what I'm interested in. <a href="https://stackoverflow.com/questions/117083/error-message-text-best-practices">Error Message Text - Best Practices</a> deals with how to make useful messages for the user, and <a href="https://stackoverflow.com/questions/116542/best-way-to-handle-error-messages">Best way to handle error messages</a> deals with where to keep error IDs vs error text. I'm more interested in debugging (because unfortunately our system DOES have lots of errors).</p>

299,619 | <p>I'd like to write a plugin that does something with the currently edited file in Eclipse. But I'm not sure how to properly get the file's full path.</p>
<p>This is what I do now:</p>
<pre><code>IFile file = (IFile) window.getActivePage().getActiveEditor.getEditorInput().
getAdapter(IFile.class);
</code></pre>
<p>Now I have an IFile object, and I can retrieve it's path:</p>
<pre><code>file.getFullPath().toOSString();
</code></pre>
<p>However this still only gives me the path relative to the workspace. How can I get the absolute path from that?</p>

299,679 | <p>In my web app, when a user logs in, I add his Id to a vector of valid Ids in the servlet, when he logs out, I remove his Id from the vector, so I can see how many current users are active, if a user forgets to log out, my servelt generated html has : </p>
<pre><code><meta http-equiv="Refresh" content="30; url=My_Servlet?User_Action=logout&User_Id=1111">
</code></pre>
<p>in the tag to automatically log him out.</p>
<p>But I've noticed many users are there for ever, never logged out. I found out why, by closing their browsers, they never manually or automatically logged out, so their user Ids will never be removed from the valid user Ids vector.</p>
<p>So, my question is : how do I detect users closing their browsers, so my servlet can remove their Ids from the vector ?</p>
<hr>
<p>I see some light at the end of the tunnel, but there is still a problem, my program has something like this : </p>
<p>Active User List :</p>
<pre><code>User_1 : Machine_1 [ IP_1 address ]
User_2 : Machine_2 [ IP_2 address ]
User_3 : Machine_3 [ IP_3 address ]
...
</code></pre>
<p>How do I know, from the session listener, which user's session has ended and therefore remove him from my list?</p>
<p>I was hoping when the session ends, the HttpServlet's <code>destroy()</code> method would be called and I can remove the user Id in there, but it never gets called when user closes his browser, why? And is there any other method in the HttpServlet that gets called when a session closes?</p>

299,704 | <p>I'm getting quite a few errors in my code. Consequently, I would like to be able to minimize them at the outset or see as many errors as possible before code execution. Is this possible and if so, how can I do this?</p>

299,719 | <p>In the Linux kernel, given the <code>task_struct</code>'s <code>mm</code> I can access the process's list of <code>vm_area_struct</code>s. Given these <code>vm_area_struct</code>s, how do I get the <code>struct page</code>s which actually correspond to this vma? </p>
<p>I tried looking for functions in mm/memory.c and the like, but I was at a loss.</p>
<p>Edit: the idea is to find which pages in the vma are currently in memory and which are not. But I <strong>don't</strong> want someone telling me how to do this bit, as that's a small part of a homework assignment that I need to figure out on my own. But I can't seem to figure out how to find the pages that correspond to this vma. If I can find the pages, I figure I can check to see if they have a valid pfn or not.</p>
