317,362 | <p>I've got in my webservice a simple <code>public boolean isAlive()</code> service.
I defined it in my WSDL :</p>
<pre><code><wsdl:types>
<xsd:element name="isAliveResponse" type="xsd:boolean">
</xsd:element>
</wsdl:types>
<wsdl:message name="isAliveResponse">
<wsdl:part element="ns:isAliveResponse" name="parameters"/>
</wsdl:message>
<wsdl:portType name="myService">
<wsdl:operation name="isAlive">
<wsdl:output message="ns:isAliveResponse"/>
</wsdl:operation>
</wsdl:portType>
<wsdl:binding name="myServiceSOAP" type="ns:myService">
<soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http" />
<wsdl:operation name="isAlive">
<soap:operation soapAction="http://myServiceURL/isAlive" />
<wsdl:input>
<soap:body use="literal" />
</wsdl:input>
<wsdl:output>
<soap:body use="literal" />
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
</code></pre>
<p>When I generate the Service skeleton the method is generated but not in the client stub. Is there a problem in the WSDL ? Should I put a wsdl:input even if the method don't have arguments (I didn't put the whole WSDL but all the other method with a "request" arg are well generated) ? And if I have to put a wsdl:input what would be it's message ?</p>
<p><strong>Edit</strong> : After validating the WSDL under Eclipse I have the warning <code>WS-I: (BP2208) wsdl:operation was not a request/response or one-way operation</code> after searching I found a description here : <a href="http://www.ws-i.org/Testing/Tools/2005/01/BP11_TAD_1-1.htm#BP2208" rel="nofollow noreferrer">http://www.ws-i.org/Testing/Tools/2005/01/BP11_TAD_1-1.htm#BP2208</a> (it seems the anchor doesn't work) so I guess the error is probably the missing wsdl:input.</p>

317,364 | <p>On Linux, the "top" command shows a detailed but high level overview of your memory usage, showing:</p>
<p>Total Memory, Used Memory, Free Memory, Buffer Usage, Cache Usage, Swap size and Swap Usage.</p>
<p>My question is, what commands are available to show these memory usage figures in a clear and simple way? Bonus points if they're present in the "Core" install of Solaris. 'sar' doesn't count :)</p>

317,374 | <p>I am trying to import a .csv file into WorldShip containing names, addresses, and zip codes. I have two profiles set up defining package weight, UPS service, bill transportation, package type, and reference numbers.</p>
<p>Can I import just name, addresses and zip codes under a specific profile to keep the other variables constant? Or do I have to add those variables to the .csv file?</p>
<p>Also, I want to be able to print shipping and return labels for several "batches" throughout the day, but only have a single end of day report. Will each batch be appended to the end of day report? The return shipping address will stay constant.</p>
<p>I have basic programming abilities and fairly good computer skills, but I want to know if I am getting in over my head. </p>
<p>Your help is greatly appreciated.</p>

317,378 | <p>When the page is done loading I call a function which puts the hover event on $('a.tooltip'). When I want to <em>unbind</em> this event I do the following: </p>
<pre><code> $('a.tooltip').unbind('mouseover mouseout');

<p>That works! However when I want rebind the hover event and I call the function that was first loaded at document ready again, it doesn't rebind the hover helper. How can I rebind it?</p>

317,381 | <p>OK, So i have been watching some MVC vids and reading some bits.
I am new to the entire MVC pattern, and until now have been happily wrapped up in the web forms world!</p>
<p>Like with so many demos it all seems great and I'm sure I'll have lots I dont understand as I move along, but in the first instance...</p>
<p>I can see that you can have a strongly typed view, which gets data from the controller. What happens if I want data in a view from different object types?? Say i want to show a grid of cars and a grid of people, which are not related in anyway??</p>
<p>Thx

317,389 | <p>I'm testing the basics for exchanging rest messages between a asp.net mvc site and a WCF 3.5 service.
The service is built using the template found in the WCF REST Starter Kit found on codeplex.
I would like to exchange json messages using jquery.
The REST Singleton service is working properly and it also provide examples of all the possible calling adding the help parameter ad the end of the uri.
I arrive to perform GET requests with the built in jquery $.getJSON.
I have problems doing the PUT (for updating values) and POST.</p>
<pre><code>$.ajax({
type: "PUT",
dataType: "json",
url: "http://localhost:1045/Service.svc/?format=json",
data: '{"Value":testvalue}'
});
</code></pre>
<p>What is the best approach for this? Is it possible not to use Ms. Ajax at all and is it correct to bypass it?</p>

317,413 | <p>I am creating a GUI frontend for the Eve Online API in Python.</p>
<p>I have successfully pulled the XML data from their server.</p>
<p>I am trying to grab the value from a node called "name":</p>
<pre><code>from xml.dom.minidom import parse
dom = parse("C:\\eve.xml")
name = dom.getElementsByTagName('name')
print name
</code></pre>
<p>This seems to find the node, but the output is below:</p>
<pre><code>[<DOM Element: name at 0x11e6d28>]
</code></pre>
<p>How could I get it to print the value of the node?</p>

317,423 | <p>I've posted this <a href="https://stackoverflow.com/questions/155739/detecting-unsaved-changes-using-javascript#317246">here</a>, but thought it might deserve a question on its own.</p>
<p>What I'm trying to do is show a dialog box that asks the user if he/she wants to leave the page if there are unsaved changes. That all works fine. But the problem is described below:</p>
<p>Has anyone come across the problem where Internet Explorer fires the onbeforeunload event twice? While Googling around, I found it has something to do with the fact that for (among others) an ASP.NET linkbutton the HTML code is <code><a href="javascript: __doPostBack...</code>. </p>
<p>Apparently, when IE encouters a link that doesn't have a <code>href="#"</code>, it fires the onbeforeunload event. Then, when you confirm the javascript dialog box we're showing, the page will do the 'real' unload to navigate to the other page, and raise the onbeforeunload event a second time.</p>
<p>A solution offered on the internet is to set a boolean variable and check on it before showing the dialog. So the second time, it wouldn't be shown. That's all well, but when the user cancels, the variable will still be set. So the next time the user wants to leave the page, the dialog won't be shown anymore.</p>
<p>Hope this is a little clear, and I hope someone has found a way around this?</p>

317,424 | <p>I am running a query from ASP using a MySQL database, I want to create a variable (ssResult) based on the result with a person's name (fullname), if the record does not exist I want to assign the text 'N/A' to the variable, code below, I currently use a function getOther for my database connections which passes the column name "fullname":</p>
<pre><code>ssResult = getOtherElse("SELECT fullname FROM table WHERE id=" & inArr(j), "fullname")
</code></pre>
<p>Below is the code for the function getOtherElse which only works when a result is returned but not when there is an empty result:</p>
<pre><code>Function getOtherElse(inSQL, getColumn)
Dim conn, rstemp
Set conn = Server.CreateObject("ADODB.Connection")
conn.open myDSN
Set Session("lp_conn") = conn
Set rstemp = Server.CreateObject("ADODB.Recordset")
rstemp.Open inSQL, conn
if not rstemp.eof then
rstemp.movefirst
getOtherElse=rstemp.fields(getColumn)
else
getOtherElse="N/A"
end if
rstemp.close
set rstemp=nothing
conn.close
set conn=nothing
End Function
</code></pre>
<p>Thanks!</p>

317,431 | <p>I am trying to set up a masterpage that contains a javascript popup subroutine that can be used in multiple web pages. The popup already works in a single page environment. I now want to migrate it to a master page. Any ideas will be greatly appreciated. I already searched this site and tried a couple of the suggestions to no avail. W small working example would help.
Thanks

<p>I have seen this in code of a co-worker (who happens to be a big Boost fan). Of all the Boost goodness out there, this has only led to confusion for me.</p>

317,462 | <p>In my everlasting quest to suck less I'm trying to understand the "yield" statement, but I keep encountering the same error.</p>
<blockquote>
<p>The body of [someMethod] cannot be an iterator block because
'System.Collections.Generic.List< AClass>' is not an iterator interface type.</p>
</blockquote>
<p>This is the code where I got stuck:</p>
<pre><code>foreach (XElement header in headersXml.Root.Elements()){
yield return (ParseHeader(header));
}
</code></pre>
<p>What am I doing wrong? Can't I use yield in an iterator? Then what's the point?
In this example it said that <code>List<ProductMixHeader></code> is not an iterator interface type.
<code>ProductMixHeader</code> is a custom class, but I imagine <code>List</code> is an iterator interface type, no?</p>
<p><strong>--Edit--</strong><br>
Thanks for all the quick answers.<br>
I know this question isn't all that new and the same resources keep popping up.<br>
It turned out I was thinking I could return <code>List<AClass></code> as a return type, but since <code>List<T></code> isn't lazy, it cannot. Changing my return type to <code>IEnumerable<T></code> solved the problem :D</p>
<p>A somewhat related question (not worth opening a new thread): is it worth giving <code>IEnumerable<T></code> as a return type if I'm sure that 99% of the cases I'm going to go .ToList() anyway? What will the performance implications be?</p>

317,472 | <p>I have a container element which I need to resize as its contents change. It contains 2 absolutely positioned divs which can both change height. If I don't specify the height of the container then anything after the container disappears under the contents. </p>
<p>At the moment I am doing the following but I'd be pleased to find a less laborious alternative:</p>
<p>(container has position:relative, #main and #sidebar are position:absolute, the contents of #sidebar have no positioning specified)</p>
<p>css:</p>
<pre><code>div#mapcontainer { position:relative; width:100%; height: 600px; }
div#main { position:absolute; top: 0; left: 10px; width: 500px; height: 400px; }
div#sidebar { position:absolute; top:10px; right:10px; width: 155px; height: 405px;}
</code></pre>
<p>html:</p>
<pre><code><div id="container">
<div id="main">variable height content here</div>
<div id="sidebar">
<div id="foo">...</div>
<div id="bar">....</div>
...
</div>
<div>
</code></pre>
<p>js:</p>
<pre><code>fixHeights = function() {
var children_height = 0;
$('#sidebar'). children().each(function(){children_height += $(this).height();});
$('#container').height(Math.max(children_height, $('#main').height()));
};
</code></pre>

317,527 | <p>I know a lot about C# but this one is stumping me and Google isn't helping.</p>
<p>I have an IEnumerable range of objects. I want to set a property on the first one. I do so, but when I enumerate over the range of objects after the modification, I don't see my change.</p>
<p>Here's a good example of the problem:</p>
<pre><code> public static void GenericCollectionModifier()
{
// 1, 2, 3, 4... 10
var range = Enumerable.Range(1, 10);
// Convert range into SubItem classes
var items = range.Select(i => new SubItem() {Name = "foo", MagicNumber = i});
Write(items); // Expect to output 1,2,3,4,5,6,7,8,9,10
// Make a change
items.First().MagicNumber = 42;
Write(items); // Expect to output 42,2,3,4,5,6,7,8,9,10
// Actual output: 1,2,3,4,5,6,7,8,9,10
}
public static void Write(IEnumerable<SubItem> items)
{
Console.WriteLine(string.Join(", ", items.Select(item => item.MagicNumber.ToString()).ToArray()));
}
public class SubItem
{
public string Name;
public int MagicNumber;
}
</code></pre>
<p>What aspect of C# stops my "MagicNumber = 42" change from being output? Is there a way I can get my change to "stick" without doing some funky converting to List<> or array?</p>
<p>Thanks!
-Mike</p>

317,576 | <p>I have a table, users, in an Oracle 9.2.0.6 database. Two of the fields are varchar - last_name and first_name.</p>
<p>When rows are inserted into this table, the first name and last name fields are supposed to be in all upper case, but somehow some values in these two fields are mixed case.</p>
<p>I want to run a query that will show me all of the rows in the table that have first or last names with lowercase characters in it.</p>
<p>I searched the net and found REGEXP_LIKE, but that must be for newer versions of oracle - it doesn't seem to work for me.</p>
<p>Another thing I tried was to translate "abcde...z" to "$$$$$...$" and then search for a '$' in my field, but there has to be a better way?</p>
<p>Thanks in advance!</p>

317,580 | <p>I'm looking for the best way to interpret the standard (well, standardish) Ethernet PHY registers, to determine the speed that an Ethernet link is actually running at. (e.g. 10/100/1000 and full/half-duplex)</p>
<p>I daresay that this is to be found in the source of things like Linux, and I'm just off to look there now, but if anyone has a good reference I'd be interested.</p>
<p>What I'm interested in is if it actually linked and what it linked at, rather than the vast sea of possibilities that each end has advertised at the outset.</p>

317,591 | <p>is it possible to create my own custom keys in the asp.net web.config file and iterate through them with C#? How do you do both (where do I put the key? what format?)? I have an application for an intranet that does certain things based upon the IP address of the client. Instead of hard coding those in the codebehind file, I thought I would put them in the web.config and iterate through that. That way I could add or remove from my configuration file without recompiling everything.</p>
<p>My key would have a name, IP address, and maybe other information.</p>
<p>Thank you.</p>

317,611 | <p>I have a view which contains a form, the form posts and the data gets processed etc, then I want to return the view Index, so return view("Index");</p>
<p>however this will then complain about my ViewData not existing, I get the feeling that the controller code under Index() isn't being processed which adds the list it requires to the ViewData, anyone know what's wrong?</p>
<p>Thanks</p>
<p>edit: Apparently it's done to prevent recursion.. in which case, I'm lost as to what to do without repeating all my ViewData stuff both Controllers</p>

317,617 | <p>I would like to write a utility that will provide me with a relatively unique ID in Java. Something pretty simple, like x bits from timestamp + y bits from random number.</p>
<p>So, how would I implement the following method:</p>
<pre><code>long getUniqueID()
{
long timestamp = System.currentTimeMillis();
long random = some random long
...
return id;
}
</code></pre>
<p>BONUS</p>
<p>Any suggestions for other easily obtainable information I could use to form my ID?</p>
<p>note: I am aware of GUIDs and I know Java has a UUID class, but I don't want something that is 128 bits long.</p>

317,619 | <p>When ever I think I can use the yield keyword, I take a step back and look at how it will impact my project. I always end up returning a collection instead of yeilding because I feel the overhead of maintaining the state of the yeilding method doesn't buy me much. In almost all cases where I am returning a collection I feel that 90% of the time, the calling method will be iterating over all elements in the collection, or will be seeking a series of elements throughout the entire collection. </p>
<p>I do understand its usefulness in linq, but I feel that only the linq team is writing such complex queriable objects that yield is useful.</p>
<p>Has anyone written anything like or not like linq where yield was useful?</p>

317,621 | <p>I have a ComboBox inside of a cell of a DataGridView Row on a Windows form. I need the following to happen: </p>
<ol>
<li>click on the ComboBox</li>
<li>pick a value</li>
<li>recalculate a total & display inside of a lable that is sitting
outside of the DataGridView.</li>
</ol>
<p>Currently, the following is happening: </p>
<ol>
<li>Click on the ComboBox</li>
<li>Click it again to open the CB's Drop-down list</li>
<li>select a value</li>
<li>click outside of the cell to force a recalculation of the
external label.</li>
</ol>
<p>I want to avoid, first, having to click the combo twice (once to set focus, and again to select the value). Second, I'd like for a live recalculation to happen after selecting a value.</p>
<p>Does anyone have a trick or two to solve any of these?</p>
<p>I've tried most of the events on the DGV without much luck.</p>

317,647 | <p>I've attempted to use the EstimatedSize value during creation of an uninstaller registry key for an app I've developed, unfortunately the value I specify does not appear in the Add/Remove Program list next to my program's entry. I've tried to find the proper procedure for using this value but to no avail. Anyone have any experience on this issue? Your help would be appreciated.</p>
<p><strong>Divo</strong> got me on the right track so I figured I'd post step-by-step instructions on how to correctly display the EstimatedSize value.</p>
<ol>
<li>Create the registry key with all relevant properties, including EstimatedSize. This value will be replicated in the ARPCache key in the registry</li>
<li>Find the registry key inside the ARPCache folder, delete the SlowInfoCache binary value, and set the Changed value to 1.</li>
<li>Next time the Add/Remove Programs list is opened you will see the value you specified in the EstimatedSize entry, not the arbitrary Windows generated one.</li>

317,684 | <p>Hi I have a view with several User Controls and I pass ViewData to all of them, I would like to know how you would determine the element count by specifying the string key.
I understand that you cannot use comparison to an integer because ViewData is an object but I have it setup this way for explaining my question. I have also tried null but The ViewData object is never null, even for results where no data is populated in the ViewData. I.e</p>
<p>In my View</p>
<pre><code> <%if(ViewData["Test"].Values > 0)
{
%>
<%=Html.RenderPartial("~/Views/UC/Test.ascx", ViewData["Test"])%>

317,687 | <p>I have a bunch of Spring beans which are picked up from the classpath via annotations, e.g.</p>
<pre><code>@Repository("personDao")
public class PersonDaoImpl extends AbstractDaoImpl implements PersonDao {
// Implementation omitted
}
</code></pre>
<p>In the Spring XML file, there's a <a href="http://static.springframework.org/spring/docs/2.5.x/api/org/springframework/beans/factory/config/PropertyPlaceholderConfigurer.html" rel="noreferrer">PropertyPlaceholderConfigurer</a> defined:</p>
<pre class="lang-xml prettyprint-override"><code><bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="/WEB-INF/app.properties" />
</bean>
</code></pre>
<p>I want to inject one of the properties from app.properites into the bean shown above. I can't simply do something like </p>
<pre class="lang-xml prettyprint-override"><code><bean class="com.example.PersonDaoImpl">
<property name="maxResults" value="${results.max}"/>
</bean>
</code></pre>
<p>Because PersonDaoImpl does not feature in the Spring XML file (it is picked up from the classpath via annotations). I've got as far as the following:</p>
<pre><code>@Repository("personDao")
public class PersonDaoImpl extends AbstractDaoImpl implements PersonDao {
@Resource(name = "propertyConfigurer")
protected void setProperties(PropertyPlaceholderConfigurer ppc) {
// Now how do I access results.max?
}
}
</code></pre>
<p>But it's not clear to me how I access the property I'm interested in from <code>ppc</code>?</p>

317,725 | <p>I have a table with almost 800,000 records and I am currently using dynamic sql to generate the query on the back end. The front end is a search page which takes about 20 parameters and depending on if a parameter was chosen, it adds an " AND ..." to the base query. I'm curious as to if dynamic sql is the right way to go ( doesn't seem like it because it runs slow). I am contemplating on just creating a denormalized table with all my data. Is this a good idea or should I just build the query all together instead of building it piece by piece using the dynamic sql. Last thing, is there a way to speed up dynamic sql?</p>

I thought it's supposed to be:</p>
<pre><code>javac file.java > log.txt

<p>or something. Instead, I see all the output on the terminal and nothing in log.txt!</p>
<p>Also, if I want to log errors too, do I do</p>
<pre><code>javac file.java 2>&1 > log.txt

The problem is, I don't know how. I cannot set the form action to search.aspx, because all my other pages which use the master form will go to search.aspx. This I don't want.</p>

317,759 | <p>I have a .NET assembly which I am accessing from VBScript (classic ASP) via COM interop. One class has an indexer (a.k.a. default property) which I got working from VBScript by adding the following attribute to the indexer: <code>[DispId(0)]</code>. It works in most cases, but not when accessing the class as a member of another object.</p>
<p>How can I get it to work with the following syntax: <code>Parent.Member("key")</code> where Member has the indexer (similar to accessing the default property of the built-in <code>Request.QueryString</code>: <code>Request.QueryString("key")</code>)?</p>
<p>In my case, there is a parent class <code>TestRequest</code> with a <code>QueryString</code> property which returns an <code>IRequestDictionary</code>, which has the default indexer.</p>
<p>VBScript example:</p>
<pre><code>Dim testRequest, testQueryString
Set testRequest = Server.CreateObject("AspObjects.TestRequest")
Set testQueryString = testRequest.QueryString
testQueryString("key") = "value"
</code></pre>
<p>The following line causes an error instead of printing "value". This is the syntax I would like to get working:</p>
<pre><code>Response.Write(testRequest.QueryString("key"))
</code></pre>
<blockquote>
<p>Microsoft VBScript runtime (0x800A01C2)<br>
Wrong number of arguments or invalid property assignment: 'QueryString'</p>
</blockquote>
<p>However, the following lines <em>do</em> work without error and output the expected "value" (note that the first line accesses the default indexer on a temporary variable):</p>
<pre><code>Response.Write(testQueryString("key"))
Response.Write(testRequest.QueryString.Item("key"))
</code></pre>
<p>Below are the simplified interfaces and classes in C# 2.0. They have been registered via <code>RegAsm.exe /path/to/AspObjects.dll /codebase /tlb</code>:</p>
<pre><code>[InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
public interface IRequest {
IRequestDictionary QueryString { get; }
}
[ClassInterface(ClassInterfaceType.None)]
public class TestRequest : IRequest {
private IRequestDictionary _queryString = new RequestDictionary();
public IRequestDictionary QueryString {
get { return _queryString; }
}
}
[InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
public interface IRequestDictionary : IEnumerable {
[DispId(0)]
object this[object key] {
[DispId(0)] get;
[DispId(0)] set;
}
}
[ClassInterface(ClassInterfaceType.None)]
public class RequestDictionary : IRequestDictionary {
private Hashtable _dictionary = new Hashtable();
public object this[object key] {
get { return _dictionary[key]; }
set { _dictionary[key] = value; }
}
}
</code></pre>
<p>I've tried researching and experimenting with various options but have not yet found a solution. Any help would be appreciated to figure out why the <code>testRequest.QueryString("key")</code> syntax is not working and how to get it working.</p>
<p>Note: This is a followup to <a href="https://stackoverflow.com/questions/299251/exposing-the-indexer-default-property-via-com-interop">Exposing the indexer / default property via COM Interop</a>.</p>

317,780 | <p>I have a MySQL table consisting of:</p>
<pre><code>CREATE TABLE `url_list` (
`id` int(10) unsigned NOT NULL auto_increment,
`crc32` int(10) unsigned NOT NULL,
`url` varchar(512) NOT NULL,
PRIMARY KEY (`id`),
KEY `crc32` (`crc32`)
);
</code></pre>
<p>When inserting data into a related table I need to lookup the primary key from this table, and using the crc32 really speeds that up whilst allowing a small index. The URLs do need to be unique, but I'd like to avoid having more index than actual data.</p>
<p>If the value isn't present I need to insert it, but using structures such as <code>INSERT IGNORE</code>, or ON <code>DUPLICATE KEY</code> either requires me to put a unique on the huge varchar, or don't take advantage of my index.</p>
<p>How can I "SELECT id else INSERT", whilst preserving the lookup speed for the 80-90% of hits that are already in the table?</p>

317,794 | <p>I am trying to see if Reg-Free COM is something we can use in our web application to ease deployment of legacy COM components. However, before I get onto looking into things like using it for Interop situations, I can't get a simple test to work. Here's what I have done :-</p>
<p>1) Create a new VB ActiveX DLL project. Left all options as default apart from turning on binary compatibility. Added a class with a simple method called "SayHello".<br>
2) Create a new c# Console app in Vs.NET 2008 (SP1). Set the CPU to x86, and added a reference to my COM DLL.<br>
3) Turned on "Isolated" for the reference<br>
4) Call my SayHello method from the c# console app - all works.<br>
5) Manually un-register the COM dll with regsvr32 /u<br>
6) Try running the console app again. The app fails with a COM error because it can't find the COM registration information. I can confirm that the manifest is present (pasted below) </p>
<p>I'm running this on Vista, 64Bit, if that makes a difference.</p>
<p>Thanks for any pointers.</p>

317,801 | <p>I need to create a new file handle so that any write operations to that handle get written to disk immediately. </p>
<p>Extra info: The handle will be the inherited STDOUT of a child process, so I need any output from that process to immediately be written to disk.</p>
<p>Studying the <code>CreateFile</code> documentation, the <code>FILE_FLAG_WRITE_THROUGH</code> flag looked like exactly what I need:</p>
<blockquote>
<p>Write operations will not go through
any intermediate cache, they will go
directly to disk.</p>
</blockquote>
<p>I wrote a very basic test program and, well, it's not working.
I used the flag on CreateFile then used <code>WriteFile(myHandle,...)</code> in a long loop, writing about 100MB of data in about 15 seconds. (I added some <code>Sleep()</code>'s). </p>
<p>I then set up a professional monitoring environment consisting of continuously hitting 'F5' in explorer. The results: the file stays at 0kB then jumps to 100MB about the time the test program ends.</p>
<p>Next thing I tried was to manually flush the file after each write, with <code>FlushFileBuffers(myHandle)</code>. This makes the observed file size grow nice and steady, as expected.</p>
<p>My question is, then, shouldn't the <code>FILE_FLAG_WRITE_THROUGH</code> have done this <strong>without</strong> manually flushing the file? Am I missing something?
In the 'real world' program, I can't flush the file, 'cause I don't have any control over the child process that's using it.</p>
<p>There's also the <code>FILE_FLAG_NO_BUFFERING</code> flag, that I can't be used for the same reason - no control over the process that's using the handle, so I can't manually align the writes as required by this flag.</p>
<p>EDIT:
I have made a separate project specifically for watching how the size of the file changes. It uses the .NET <a href="http://msdn.microsoft.com/en-us/library/system.io.filesystemwatcher.aspx" rel="noreferrer"><code>FileSystemWatcher</code></a> class. I also write less data - around 100kB in total.</p>
<p>Here's the output. Check out the seconds in the timestamps.</p>
<p>The 'builtin no-buffers' version: </p>

317,816 | <p>I can create a literal long by appending an L to the value; why can't I create a literal short or byte in some similar way? Why do I need to use an int literal with a cast?</p>
<p>And if the answer is "Because there was no short literal in C", then why are there no short literals in C?</p>
<p>This doesn't actually affect my life in any meaningful way; it's easy enough to write (short) 0 instead of 0S or something. But the inconsistency makes me curious; it's one of those things that bother you when you're up late at night. Someone at some point made a design decision to make it possible to enter literals for some of the primitive types, but not for all of them. Why?</p>

317,835 | <p>Is there some equivalent of "friend" or "internal" in php? If not, is there any pattern to follow to achieve this behavior? </p>
<p><strong>Edit:</strong>
Sorry, but standard Php isn't what I'm looking for. I'm looking for something along the lines of what ringmaster did.</p>
<p>I have classes which are doing C-style system calls on the back end and the juggling has started to become cumbersome. I have functions in object A which take in object B as a parameter and have to call a method in object B passing in itself as an argument. The end user could call the method in B and the system would fall apart.</p>

317,857 | <p>I have a bash script which will be run on a Mac via ssh. The script requires a particular network drive to already be mounted. On the Mac, I mount this drive by opening a folder "JPLemme" on that drive in Finder. This mounts the drive until the Mac goes to sleep at night.</p>
<p>Obviously, Finder isn't available via ssh, so I want to create an AppleScript that will simulate what I do through the GUI. I've tried:</p>
<pre><code>tell application "Finder"
activate
open "JPLemme"
end tell
</code></pre>
<p>I receive the following error:</p>
<pre><code>execution error: Finder got an error: Can't get "JPLemme". (-1728)
</code></pre>
<p>I assume I'm missing something obvious, but Google has failed me. I would also be willing to entertain better solutions like mounting the drive directly; I've avoided that approach because I don't want the Mac to choke trying to mount the drive a second time after I've already mounted it in an unexpected way. (I don't really like Macs or AppleScript...)</p>

317,869 | <p>I'm aiming to create a set of objects, each of which has a unique identifier. If an object already exists with that identifier, I want to use the existing object. Otherwise I want to create a new one. I'm trying not to use the word Singleton, because I know it's a dirty word here...</p>
<p>I can use a factory method:</p>
<pre><code> // A map of existing nodes, for getInstance.
private static Map<String, MyClass> directory = new HashMap<String, MyClass>();
public static MyClass getInstance(String name) {
MyClass node = directory.get(name);
if(node == null) {
node == new MyClass(name);
}
return node;
}
</code></pre>
<p>Or equally, I could have a separate MyClassFactory method.</p>
<p>But I had intended to subclass MyClass:</p>
<pre><code>public class MySubClass extends MyClass;
</code></pre>
<p>If I do no more, and invoke MySubClass.getInstance():</p>
<pre><code>MyClass subclassObj = MySubClass.getInstance("new name");
</code></pre>
<p>... then subclassObj will be a plain MyClass, not a MySubClass.</p>
<p>Yet overriding getInstance() in every subclass seems hacky.</p>
<p>Is there a neat solution I'm missing?</p>
<hr>
<p>That's the generalised version of the question. More specifics, since the answerers asked for them.</p>
<p>The program is for generating a directed graph of dependencies between nodes representing pieces of software. Subclasses include Java programs, Web Services, Stored SQL procedures, message-driven triggers, etc.</p>
<p>So each class "is-a" element in this network, and has methods to navigate and modify dependency relationships with other nodes. The difference between the subclasses will be the implementation of the <code>populate()</code> method used to set up the object from the appropriate source.</p>
<p>Let's say the node named 'login.java' learns that it has a dependency on 'checkpasswd.sqlpl':</p>
<pre><code>this.addDependency( NodeFactory.getInstance("checkpasswd.sqlpl"));
</code></pre>
<p>The issue is that the checkpasswd.sqlpl object may or may not already exist at this time.</p>

<p>The linq extension methods for ienumerable are very handy ... but not that useful if all you want to do is apply some computation to each item in the enumeration without returning anything. So I was wondering if perhaps I was just missing the right method, or if it truly doesn't exist as I'd rather use a built-in version if it's available ... but I haven't found one :-)</p>
<p>I could have sworn there was a .ForEach method somewhere, but I have yet to find it. In the meantime, I did write my own version in case it's useful for anyone else:</p>
<pre><code>using System.Collections;
using System.Collections.Generic;
public delegate void Function<T>(T item);
public delegate void Function(object item);
public static class EnumerableExtensions
{
public static void For(this IEnumerable enumerable, Function func)
{
foreach (object item in enumerable)
{
func(item);
}
}
public static void For<T>(this IEnumerable<T> enumerable, Function<T> func)
{
foreach (T item in enumerable)
{
func(item);
}
}
}
</code></pre>
<p>usage is:</p>
<p><code>myEnumerable.For<MyClass>(delegate(MyClass item) { item.Count++; });</code></p>

317,878 | <p>I've got a few dozen Linux machines running <code>cron</code> and I'd like to put the crontabs in some sort of revision control system. For source control I use Mercurial (<code>hg</code>), so that'd be ideal, but if there's some other system that is better suited to this task I'd consider it.</p>
<p>One aspect which is specific to my situation is that all the crontabs belong to a common user (not a real person, but a placeholder "services" login). I'd like the revision history to include the actual author of each change, rather than the special account where the cron jobs actually run.</p>

I use a different config file for the local and remote because of the sql server login. Local is windows auth and remote is sql server auth. However, none of that info is stored in global.asax. global.asax only has</p>
<p>but once it is uploaded, something causes the remote to try finding the local web.config's sql server login. Deleting global.asax on the remote causes everything to work fine. </p>

317,921 | <p>I'm just beginning to learn ASP.NET MVC and I've run into a question. I'm trying to determine whether I should use HtmlHelper to create client controls or if I should just roll my own. My gut wants to lean towards just rolling my own because it gives me total control - and use jQuery to decorate and add cross-browswer functionality. But then I can see advantages of using HtmlHelper for various complex controls that may involve things like paging.</p>
<p>I'm looking for experiences about when it was better to use HtmlHelper and when it was better to roll your own.</p>

317,944 | <p>I have to change some connection strings in an incredibly old legacy application, and the programmers who made it thought it would be a great idea to plaster the entire app with connection strings all over the place.</p>
<p>Visual Studio's "current project" search is incredible slow, and I don't trust Windows Search.</p>
<p>So, what's the best free, non-indexed text search tool out there? All it should do is return a list with files that contain the wanted string inside a folder and its subfolders. </p>
<p>I'm running Windows 2003 Server.</p>

317,963 | <p>Say we have normal distribution n(x): mean=0 and \int_{-a}^{a} n(x) = P.</p>
<p>What is the easiest way to compute standard deviation of such distribution? May be there are standard libraries for python or C, that are suitable for that task?</p>

317,967 | <p>I am developing on a LAMP(erl) stack and know of several ways to store obscured passwords. I'd like to hear from those who feel they have a best practice, given MySQL 4.1.1 and Perl 5.8, and the reasons why it's the best.</p>
<p>One option I have read about, using the MySQL ENCODE() and DECODE() functions, sounds pretty good to me... your thoughts?</p>

317,973 | <p>I have just realized I've been coercing binding/dependency properties and not really fundamentally understanding the concept.</p>
<p>Heres the dependency property:</p>
<pre><code>public string Problem
{
get { return (string)GetValue(ProblemProperty); }
set { SetValue(ProblemProperty, value); }
}
public static readonly DependencyProperty ProblemProperty =
DependencyProperty.Register(
"Problem",
typeof(string),
typeof(TextBox));
</code></pre>
<p>The XAML is as so:</p>
<pre><code><TextBlock Text="{Binding Path=Problem}"/>
</code></pre>
<p>I'm manually setting the <code>Problem</code> property to a value in the constructor of the object but it doesn't update the <code>TextBlock</code> accordingly . . . any ideas? I've tried <code>Mode="OneWay"</code> and <code>Mode="TwoWay"</code> on the binding and it still doesn't work.</p>
<p>I thought this was supposed to work automatically? Or am i fundamentally getting something wrong?</p>
<p>Thanks</p>

317,981 | <p>I have a rich client application that uses Castle Windsor. At the moment all the assemblies including the application exe are in the one folder but it all looks rather untidy. I would like to put my dlls inside a subfolder such as "bin" but this prevents Castle from locating types etc when called upon. In fact the app crashes at start up. </p>
<p>Is there a way to tell Castle to look somewhere else for the files?</p>

318,018 | <p>In the admin section of a website i am building i would like to put together a dashboard page, or 'quick look' type page where the most recent changes/additions/etc in several different areas can be viewed.</p>
<p>I was thinking the best way to do this would be to use partials and have each partial contain the markup for the data i need to display. </p>
<p>My question is, is this the best approach? and if so, how do i separate the logic and presentation of these partials? For instance how do i put the logic in the dashboard controller, but keep the presentation in the partial rhtml?</p>

318,056 | <p>Not sure what's going on here.</p>
<p>I have a DateTime object, and when I try:</p>
<pre><code>String.Format( "{0:dd/MM/yyyy}", _date)
</code></pre>
<p>the value returned is:</p>
<pre><code>"24-05-1967"
</code></pre>
<p>What I want is</p>
<pre><code>"24/05/1967"
</code></pre>
<p>Can anyone explain why my format string is being ignored? </p>
<p>A bit more background:
This is a web app which started out life as .net 1.1, and I'm in the process of moving it up to 2.0/3.5. </p>
<p>Update:</p>
<p>If I change the format to {0:dd:MM:yyyy}, it returns 24:05:1967 - it's only the / in the format string that gets changed to the - char.</p>
<hr>
<p>Resolution:</p>
<p>When updating the app to run under 2.0, the asp.net globalization settings were messed up. </p>
<p>From the web site properties, ASP.NET tab, Edit Configuration, Application Tab - the culture and UI Culture were both set to the first item in the list (af-ZA) for some bizarre reason. </p>

<pre><code>if((radButton1.checked == false)&&(radButton2.checked == false))
{
txtTitle.Text = "go to work";
}
</code></pre>
<p>The dilemma is "go to work" is not executed if radButton1 is false and radButton2 is true. Shouldn't it require both conditions to be false in order to skip the statement?</p>

318,069 | <p>Let's say we're tracking the end-user IP for a web service:</p>
<pre><code>ip = Request.ServerVariables("HTTP_X_FORWARDED_FOR")
If ip = "" Then
ip = Request.ServerVariables("REMOTE_ADDR")
End If
</code></pre>
<p>I've read that this is the best method of retrieving end-user IP because it works even for users on a transparent proxy.</p>
<p>If we're using the end-user IP address to filter malicious users, are there are any security implications with the above method instead of, say, just using Request.ServerVariables("REMOTE_ADDR")?</p>
<p>For example, if we banned a malicious user by end-user IP, could they easily change their IP via a proxy and continue using our web service?</p>
<p>Thanks in advance for your help.</p>

318,087 | <p>I'm trying to map a joined-subclass scenario using Fluent NHibernate.
I have a class Entity defined in the namespace Core, and a class
SubClass : Entity in the namespace SomeModule</p>
<p>Now I obviously don't want class Entity to know about its derived
types, the SomeModules namespace references Core - not the other way
around.</p>
<p>All the examples I've been able to find use something like:</p>
<pre><code>public class EntityMap : ClassMap<Entity> {
public EntityMap() {
Id(x => x.Id)
var subClassMap = JoinedSubClass<SubClass>("SubClassId", sub => sub.Map(x => x.Id));
subClassMap.Map(x => x.SomeProperty)
...
}
}
</code></pre>
<p>This simply won't work in my situation - I need something akin to the
NHibernate xml mapping:</p>
<pre><code><joined-subclass name="SubClass" extends="Entity, Core" >
<key column="SubClassId" foreign-key="FK_KollegiumEntity"/>
<property name="Name" length="255" not-null="true" />
...
</joined-subclass>
</code></pre>
<p>Has anyone achieved this with Fluent NHibernate?</p>

318,090 | <p>Simple question:</p>
<p>How do I do this on one line:</p>
<pre><code>my $foo = $bar->{baz};
fizz(\$foo);
</code></pre>
<p>I've tried \$bar->{baz}, \${$bar->{baz}}, and numerous others. Is this even possible?</p>
<p>-fREW</p>
<p><strong>Update</strong>: Ok, the hashref is coming from DBI and I am passing the scalar ref into template toolkit. I guess now that I look more closely the issue is something to do with how TT does all of this. Effectively I want to say:</p>
<pre><code>$template->process(\$row->{body}, $data);
</code></pre>
<p>But TT doesn't work that way, TT takes a scalar ref and puts the data there, so I'd have to do this:</p>
<pre><code>$template->process(\$row->{body}, $shopdata, \$row->{data});
</code></pre>
<p>Anyway, thanks for the help. I'll at least only have one reference instead of two.</p>

318,144 | <p>My question is similar to "<a href="https://stackoverflow.com/questions/156362/what-is-the-difference-between-include-and-extend-in-ruby">What is the difference between include and extend in Ruby?</a>".</p>
<p>What's the difference between <code>require</code> and <code>include</code> in Ruby? If I just want to use the methods from a module in my class, should I <code>require</code> it or <code>include</code> it?</p>

318,155 | <p>I'm evaluating subversion's branch/merge capabilities, and I decided to do a simple test - I branched an existing project, changed a comment in one file, and then did a merge reintegrate via Tortoise.</p>
<p>It failed:</p>
<blockquote>
<p>Command: Reintegrate merge <a href="https://oscar/svn/Baxtech/ViM/Branches/Test3" rel="nofollow noreferrer">https://oscar/svn/Baxtech/ViM/Branches/Test3</a> into C:\Inntec\VS2008\Baxtech\ViM<br>
Error: Cannot reintegrate from '<a href="https://oscar/svn/Baxtech/ViM/Branches/Test3" rel="nofollow noreferrer">https://oscar/svn/Baxtech/ViM/Branches/Test3</a>' yet:<br>
Error: Some revisions have been merged under it that have not been merged<br>
Error: into the reintegration target; merge them first, then retry. </p>
</blockquote>
<p>I googled around for this, and I found some posts saying that this has to do with mergeinfo being created by renames and directory changes in old versions of Tortoise.</p>
<p>I did recently upgrade from the previous version of Tortoise to 1.5.5, however it seems like this problem was pre-1.5.*... <strong>And I only changed some comments in one file. I didn't do any renames or directory structure changes.</strong></p>
<p>Then again, we've been working with the trunk for some time (without any branching), so maybe the problem exists in there?</p>
<p>So, if there is a fix for this I would appreciate really appreciate some help. Also, though - is this typical? This was really a <em>very</em> simple test, and sadly right now I'm a little scared to use Subversion for branching.</p>
<p>Subversion: 1.5.4 (via VisualSVN Server)<br>
Tortoise: 1.5.5</p>
<p>We're also using Visual Studio 2008.</p>
<p>Thanks!</p>
<p>Brian</p>

318,157 | <p>I'm trying to get distinct results using the Criteria API in NHibernate. I know this is possible using HQL, but I would prefer to do this using the Criteria API, because the rest of my app is written using only this method. I <a href="http://forum.hibernate.org/viewtopic.php?t=941669," rel="noreferrer">found this forum post</a>, but haven't been able to get it to work. Is there a way with the criteria API to get distinct result sets?</p>
<p>Edit: In doing this, I also wanted to exclude the Primary Key column, which is also an identity, and get the remaining distinct records. Is there a way to do this? As it is, the distinct records are returning duplicates because the primary key is unique for each row, but all other fields are the same.</p>

318,158 | <p>I am trying to set the margin of an object from JavaScript. I am able to do it in Opera & Firefox, but the code doesn't work in Internet Explorer.</p>
<p>Here is the JavaScript I have:</p>
<pre class="lang-js prettyprint-override"><code>function SetTopMargin (ObjectID, Value)
{
document.getElementById(ObjectID).style.marginTop = Value.toString() + "px";
}
</code></pre>
<p>And it is called like this:</p>
<pre class="lang-js prettyprint-override"><code>SetTopMargin("test_div_id", 100);
</code></pre>
<p>So does anyone know some code that will work in Internet Explorer?</p>

318,175 | <p>Does anyone know, or have a link to an article or a step by step tutorial, that would tell me how to distribute a .net MONO application with a minimum install? The full package of Mono is like 75 MB but I know al lot of that is the compiler and libraries that I don't need.</p>
<p>I just want the minimum runtime files.</p>
<p>What files would I need to distribute for a simple 'Hello World' WinForms app?</p>
<p>I tried just deleting files until I came up with something that worked but it only worked on the machine that had Mono installed on it. Here are the files I tried</p>
<p>I created a directory for my app. In that directory I created two more directories</p>
<ul>
<li><code>\bin</code></li>
<li><code>\lib\mono\2.0</code></li>
</ul>
<p>in the <code>\mono\lib\mono\2.0</code> I put the <code>mscorlib.dll</code> file
in the <code>\bin</code> directory I put the following</p>
<ul>
<li><code>Accessibility.dll</code></li>
<li><code>MyApp.exe </code>(this is the basic World I did in VS2005)</li>
<li><code>iconv.dll</code>,</li>
<li><code>intl.dll</code>,</li>
<li><code>libglib-2.0-0.dll</code>,</li>
<li><code>libgthread-2.0-0.dll</code>,</li>
<li><code>Microsoft.VisualBasic.dll</code>,</li>
<li><code>mono.dll</code>,</li>
<li><code>mono.exe</code>,</li>
<li><code>Mono.Posix.dll</code>,</li>
<li><code>System.dll</code>,</li>
<li><code>System.Drawing.dll</code>,</li>
<li><code>System.Windows.Forms.dll</code></li>
</ul>
<p>Then, from the <code>\bin</code> directory I ran 'mono <code>MyApp.exe</code>' and it worked on my Mono installed machine but no others.</p>
<p>What I'd prefer is an 'xcopy' solution where there would be no actual installation necessary but just need the runtime files included (like when you run from a thumb drive)</p>
<p>Please note that this is to run on a Windows computer, not a Linux box.</p>
<hr />
<p>I tried running mkbundle2 (it is a .net 2.0 app) and got this error</p>

318,186 | <p>We have to accept large file uploads (video content) and want to do that in a way that works well across all standards-compliant browsers and plug-ins. Our current setup looks like this:</p>
<ul>
<li><a href="http://swfupload.org" rel="nofollow noreferrer">SWFUpload</a></li>
<li>input type="file" for graceful degradation</li>
</ul>
<p>On the server-side, we have <a href="http://nginx.net/" rel="nofollow noreferrer">nginx</a> and the <a href="http://www.grid.net.ru/nginx/upload.en.html" rel="nofollow noreferrer">upload module</a> streaming the uploaded files into the server, then handing the requests off to a merb app.</p>
<p>Unfortunately, it looks like the recently released Adobe Flash Player 10 broke every single free/open uploading flash component out there (and then, some other sites which have their own proprietary versions as well), but some other sites, such as <a href="http://flickr.com" rel="nofollow noreferrer">Flickr</a> and <a href="http://vimeo.com" rel="nofollow noreferrer">Vimeo</a>, seem to work just fine.</p>
<p>I've been poking around looking for other ways of doing this, but since compatibility with both Flash 9 and 10 is mandatory, I couldn't find a suitable solution. Any ideas?</p>

318,199 | <p>I'm planning to write a javascript-based web application. I'm wondering what the best way to implement it in terms of file stucture is.</p>
<p>There is one main page (main.html) containing a menu and a main div section. The way it works is simple: When the user clicks on one of the links in the menu (for example 'Page 1'), the content of the div section is refreshed with the content of the page1.html file. This is done using javascript (jquery). If the user clicks on 'Page 2', the content of the page2.html file is loaded into the div section, etc.</p>
<p>Each page has its own javascript code and as I prefer to keep it separate I've implemented a sort of 'code behind' like in asp.net:</p>
<p><b>page1.html</b>:<br>
< script type="text/javascript" src="<b>page1.js"</b> >< /script> <br>
<... html code ...>
<br><br>
<b>page2.html</b>:<br>
< script type="text/javascript" src="<b>page2.js"</b> >< /script > <br>
<... html code ...></p>
<p>When the user clicks on 'Page 1', the content of the page1.html file is loaded into the main div section of main.html. As page1.html is referencing page1.js, the javascript code in page1.js is also loaded.</p>
<p>This seems to work fine but I'm wondering if it is the best way to implement this. At some point I was thinking of referencing all the javascript files in main.html This would also work fine but it would mean all the javascript files would have to be loaded in memory even if they are not going to be used. With the 1st approach, a javascript file is only loaded in memory before being actually used.</p>
<p>Any ideas? What are the 'best practises' for this? Keep in mind that this is a web application (as opposed to a website). It will be available over the internet but only to some users (and it will be password protected) so I don't care about SEO etc.</p>

318,208 | <p>Is it possible to cast an object in Java to a combined generic type?</p>
<p>I have a method like:</p>
<pre><code>public static <T extends Foo & Bar> void doSomething(T object) {
//do stuff
}
</code></pre>
<p>Calling this method is no problem if I have a class that implements both interfaces (Foo & Bar).</p>
<p>The problem is when I need to call this method the object I need to pass to it is received as <code>java.lang.Object</code> and I need to cast it to make the compiler happy. But I can't figure out how to make this cast.</p>
<p>edit:</p>
<p>The problem lies in a function like this:</p>
<pre><code>public void problemFunction (Object o) {
if ( o instanceof Foo && o instanceof Bar) {
doSomething((Problematic cast) o);
}
}
</code></pre>
<p>}</p>

318,210 | <p>I'm trying to assert that one object is "equal" to another object. </p>
<p>The objects are just instances of a class with a bunch of public properties. Is there an easy way to have NUnit assert equality based on the properties?</p>
<p>This is my current solution but I think there may be something better:</p>
<pre><code>Assert.AreEqual(LeftObject.Property1, RightObject.Property1)
Assert.AreEqual(LeftObject.Property2, RightObject.Property2)
Assert.AreEqual(LeftObject.Property3, RightObject.Property3)
...
Assert.AreEqual(LeftObject.PropertyN, RightObject.PropertyN)
</code></pre>
<p>What I'm going for would be in the same spirit as the CollectionEquivalentConstraint wherein NUnit verifies that the contents of two collections are identical.</p>

318,236 | <p>I don't need to validate that the IP address is reachable or anything like that. I just want to validate that the string is in dotted-quad (xxx.xxx.xxx.xxx) IPv4 format, where xxx is between 0 and 255.</p>

318,239 | <p>How do I set environment variables from Java? I see that I can do this for subprocesses using <a href="http://docs.oracle.com/javase/7/docs/api/java/lang/ProcessBuilder.html" rel="noreferrer"><code>ProcessBuilder</code></a>. I have several subprocesses to start, though, so I'd rather modify the current process's environment and let the subprocesses inherit it.</p>
<p>There's a <code>System.getenv(String)</code> for getting a single environment variable. I can also get a <code>Map</code> of the complete set of environment variables with <code>System.getenv()</code>. But, calling <code>put()</code> on that <code>Map</code> throws an <code>UnsupportedOperationException</code> -- apparently they mean for the environment to be read only. And, there's no <code>System.setenv()</code>.</p>
<p>So, is there any way to set environment variables in the currently running process? If so, how? If not, what's the rationale? (Is it because this is Java and therefore I shouldn't be doing evil nonportable obsolete things like touching my environment?) And if not, any good suggestions for managing the environment variable changes that I'm going to need to be feeding to several subprocesses?</p>

318,241 | <p>I am trying to use symbolic links in one of the applications I have running on Tomcat5. Thanks to some help from <a href="https://stackoverflow.com/questions/315093/configure-symlinks-for-single-directory-in-tomcat">another StackOverflow question</a> I was able to do it
by creating a context.xml file in</p>
<p>/...myapplication/META-INF/context.xml</p>
<p>I am now trying to implement this on a production server. However, there are other applications running on it. And there is another context file</p>
<p>/...tomcat/conf/context.xml</p>
<p>It seems to me these are setting configurations server-wide to all applications. If I allowLinks in the conf/context.xml file, my symbolic links work. If I don't allowLinks in conf/context.xml, my application's symbolic links do not work, even though I have allowed them in the META-INF/context.xml</p>
<p>My question is, does the conf/context.xml control all applications? If I want symbolic links to work only in one application, do I need to remove the conf/context.xml and create new context files for each application? Or is there a way I can allow symbolic links in myapplication only?</p>

318,265 | <p>I'm trying to launch another process from a service (it's a console app that collects some data and writes it to the registry) but for some reason I can't get it to launch properly.</p>
<p>I basics of what I'm am trying to do is as follows:</p>
<ol>
<li>Launch the process</li>
<li>Wait for the process to finish</li>
<li>Retrieve the return code from the process</li>
</ol>
<p>I am currently using the following code:</p>
<pre><code>STARTUPINFO info={sizeof(info)};
PROCESS_INFORMATION processInfo;
if (CreateProcess(PATH, ARGS, NULL, NULL, TRUE, 0, NULL, NULL, &info, &processInfo))
{
::WaitForSingleObject(processInfo.hProcess, INFINITE);
DWORD exit = 100;
GetExitCodeProcess(processInfo.hProcess, &exit);
CloseHandle(processInfo.hProcess);
CloseHandle(processInfo.hThread);
return exit;
}
</code></pre>
<p>Upon calling CreateProcess(), it succeeds and enters the body of the if statement. The call to WaitForSingleObject returns immediately, which it should not, as the process should take approximately 20-30 seconds to finish. And, finally, calling GetExitCodeProcess() fails and does not set the value "exit".</p>
<p>FYI, this is code I have actually used elsewhere with success, just not in a service.</p>
<p>Could it be that it's being launched from a service and there are permissions issues?? </p>
<p><strong>Edit:</strong> I've now realized that it will actually launch the app (I can see it in TaskMan) but it seems to be stuck. It's there, but isn't doing anything.<br>
Based on Rob Kennedy's <a href="https://stackoverflow.com/questions/318265/launching-a-process-from-a-service#318314">suggestion</a>, I fixed the process handle issue, and it actually does wait for the process to finish. But it never does finish unless I kill it manually.</p>

318,334 | <p>I've got a program that tends to crash quite often while I'm asleep and I need to keep it running. So I thought I might writeup a vb6 application that monitors the process list, if something disappears it will relaunch it. Anyone know of an easy way?</p>

318,336 | <p>I'm using the Fish Gadget (<a href="http://abowman.com/google-modules/fish/" rel="noreferrer">http://abowman.com/google-modules/fish/</a>) within a wiki based CMS, and need to reposition the gadget from one HTML element to another. (Note: the fish gadget is an example -- the problem occurs with other gadgets as well.)</p>
<p>If I directly reposition the gadget using the gadgets base class "ig_reset", then everything works. If I try to reposition using a surrounding wrapper, then the iframe used by the gadget seems to take over. Unfortunately I need the flexibility of repositioning using the surrounding wrapper. </p>
<p>This seems to have something to do with moving a SCRIPT tag around in the DOM. The gadget dynamically creates a script and a style tag. If I <em>remove</em> the dynamically created script tag from the DOM, and then reposition the wrapper to another location in the DOM, all works well. If I try to <em>move</em> the script tag to another DOM element then the original problem occurs. So <em>moving</em> a script tag around the DOM seems to be the cause -- regardless of when the move occurs (even post-load).</p>
<p>I'd like to understand what is happening here to cause the frame to take over the page, and also find a better solution than removing the dynamically created script tag.</p>
<p>I put a test up here: <a href="http://solidgone.com/jquery/google-gadget.html" rel="noreferrer">http://solidgone.com/jquery/google-gadget.html</a> -- the demo uses jQuery, but I don't think this is related to jQuery...</p>
