349,366 | <p>I've notice an issue - it feels like a bug but I suspect a 'feature' - in SSMS in SQL Server 2008.</p>
<p>I have various tabs open, for example an alter table script in one table and a SProc that queries that table in another tab, and when I execute my Alter Table script the changes are not reflected in Intellisense in the other tab.</p>
<p>I can create new queries and the changes are still not reflected in Intellisense. If I open a new SSMS instance, the changes are reflected, until I make further changes, of course.</p>
<p>However, if you over-rule Intellisense and push ahead with your modified tables and code, everything compiles without a grumble (as expected).</p>
<p>Is this a bug? A feature? Is there a setting somewhere that alters this behaviour? I checked in the options but couldn't see anything</p>

349,369 | <p>I want to send some strings in a list in a POST call. eg:</p>
<pre><code> www.example.com/?post_data = A list of strings

<p>The python code receives the data as a single string (Instead of a list of strings). How do I post it as a list of strings?</p>

349,387 | <p>I am testing a couple of workflows for their workflow history cleanup time intervals. The workflow History needs to be retained for a specific number of days. I have implemented the solutions recommended <a href="http://mdablog.spaces.live.com/Blog/cns!B0C40902E1212960!796.entry" rel="nofollow noreferrer">here</a> </p>
<p>My problem is that, now I need to test my code to see if the workflow history is getting cleaned up after the exact number of days. </p>
<p>I came to know that the workflow history is cleanep up by a timer job called "Workflow Auto Cleanup" which runs daily.</p>
<p>But in my case, the workflow History cleanup does not seem to run, because, in "Central Administration > Operations > Timer Job Definitions > Edit Timer Job" , the last run time is shown as "N\A"</p>
<p>Is there anything I am missing here? What should I do to make this timer job run properly?</p>
<p>Update: Checking the SharePoint logs gives this message:
"Upgrade job definition already exists, waiting for the existing upgrade to complete"</p>

349,410 | <p>I have a registry value which is stored as a binary value (REG_BINARY) holding information about a filepath. The value is read out into an byte array. But how can I transform it into a readable string?</p>
<p>I have read about system.text.encoding.ASCII.GetString(value) but this does not work. As far as I got to know the registry value is arbitrary binary data and not ASCII which is the reason for the method to produce useless data.</p>
<p>Does anybody know how I can convert the data? </p>
<p>Sample:
(A piece of the entry)</p>
<pre><code>01 00 00 00 94 00 00 00 14 00 00 00 63 00 3A 00 5C 00
70 00 72 00 6F 00 67 00 72 00 61 00 6D 00 6d 00 65 00
5C 00 67 00 65 00 6D 00 65 00 69 00 6E 00 73 00 61 00
6D 00 65 00 20 00 64 00 61 00 74 00 65 00 69 00 65 00
6E 00 5C
</code></pre>
<p>Due to the regedit this is supposed to be:</p>
<pre><code>............c.:.\.p.r.o.g.r.a.m.m.e.\.g.e.m.e.i.n.s.a.m.e. .d.a.t.e.i.e.n.\
</code></pre>
<p>The entry itself was created from Outlook. It's an entry for an disabled addin item (resiliency)</p>

349,446 | <p>I am given a problem where I have been given N nodes in a graph that are interconnected to each other then given a matrix which lists down a node being connected to another (1 if it is, 0 if not). I am wondering how to best approach this problem. I think these are adjacency matrix? But how would I implement that ...</p>
<p>Basically what I am trying to get out of these is find whether a particular node is connected to all other nodes in a given set 'S'. And whether selected items are clique or not...</p>

349,513 | <p>I'm looking for a way to easily load test and benchmark some of our SQL (using ADO.NET, nothing fancy using LINQ or PLINQ) that has to be performant when running under high parallel load.</p>
<p>I've thought of using the new parallel extensions CTP and specifically <code>Parallel.For</code> / <code>Parallel.ForEach</code> to simply run the SQL over 10k iterations or so - but I've not been able to find any data on what these have been optimized for.</p>
<p>Essentially I'm worried that because database access is inherently I/O bound, it won't create sufficient load. Does anyone know if Parallel. For is intelligent enough to use > x threads (where x = # of CPUs) if the tasks it is executing are not totally CPU bound? I.e. does it behave in a similar manner to the managed thread pool?</p>
<p>Would be rather cool if it was so!</p>
<p><b>EDIT: As @CVertex has kindly referred to below, you can set the number of threads independently. Does anyone know if the parallel libraries by default are intelligent enough to keep adding threads if a job is I/O bound?</b></p>

349,524 | <p>In my SQL Server backend for my app, I want to create history tables for a bunch of my key tables, which will track a history of changes to the rows.</p>
<p>My entire application uses Stored Procedures, there is no embedded SQL.
The only connection to the database to modify these tables will be through the application and the SP interface.
Traditionally, shops I've worked with have performed this task using triggers.</p>

Which is faster?</p>

349,544 | <p>There is <code>ConnectionManager</code> which waits for incoming connections. For each incoming connection it creates a <code>Connection</code> instance which handles the inbound and outbound traffic on this connection. Each <code>Connection</code> has a <code>Watchdog</code> which handles "bad connection" conditions and calls registered "Listerners". One "Listener" is the <code>ConnectionManager</code> which closes the connection and deletes the <code>Connection</code> instance which in turn deletes the corresponding Watchdog.</p>
<p>Wait. A. Minute.</p>
<p>The <code>Watchdog</code> calls the <code>ConnectionManager</code> which deletes the <code>Connection</code> which deletes the <code>Watchdog</code>? The Watchdog chases its own tail.</p>
<p>I am completly blocked. How do I resolve this?</p>
<hr>
<p><strong>Solution</strong>: I will make the Listener thingy asynchronous, altough I don't know yet how to do that without too much pain. The <code>Watchdog</code> doesn't know about the <code>ConnectionManager</code>. It is fairly generic. Also the Win32-Thread-API doesn't have something like "join", so I might need to roll my own with <code>GetExitCodeThread()</code> and <code>STILL_ACTIVE</code>...</p>
<p>Thanks, guys.</p>

349,603 | <p>I wanted to start with the use of Remoting under C# in a testdriven way, but I got stuck.</p>
<p>One thing I found on the topic is this <a href="http://www.codeproject.com/KB/architecture/TddRemoting.aspx" rel="nofollow noreferrer">article by Marc Clifton</a>, but he seems to have the server running by starting it manually from the console.</p>
<p>I try to have the server started (i.e. register the serving class) in the test fixture.
I probably also have the usage of the interface wrong, but that will come later.</p>
<p>I always get an Exception (sorry for the german message) that the channel is registered already.
System.Runtime.Remoting.RemotingException : Der Channel tcp wurde bereits registriert.</p>
<p>After commenting out the ChannelServices.RegisterChannell() line in the test method, it occurs for the call Activator.GetObject().</p>
<p>I tried to put the StartServer() into a thread, but that did not help either.
I found that creating a new AppDomain might be a possible way, but have not tried yet.</p>
<p>Can you tell me, if my approach is inherently wrong? How can I fix it?</p>

349,612 | <pre><code>$(document).ready(function() {

<p>I'm not a javascript expert, but I've cobbled together a few functions using jQuery. </p>
<p>In this case, the stylesheet hides some controls. When the user mouses over, this function exposes those controls. </p>
<p>This works on every browser but Firefox (on the Mac and Windows). Am I missing something obvious? </p>

349,613 | <p>Hopefully an easy question, but I'd quite like a technical answer to this!</p>
<p>What's the difference between:</p>
<pre><code>i = 4
</code></pre>
<p>and</p>
<pre><code>Set i = 4
</code></pre>
<p>in VBA? I know that the latter will throw an error, but I don't fully understand why.</p>

349,614 | <p>i have the following javascript code:</p>
<p><a href="http://www.nomorepasting.com/getpaste.php?pasteid=22561" rel="nofollow noreferrer">http://www.nomorepasting.com/getpaste.php?pasteid=22561</a></p>
<p>Which works fine(the makewindows function has been changed to show it is a php variable), however the html contains unicode characters, and will only be assigned characters leading up to the first unicode character. If I make a small test file and echo out article_desc directly, all the html is output, although quetsions marks are displayed instead of the correct symbols. However json_encode seems to cut short the html, resulting in errors. </p>
<p>edit: here is a dump straight from the mysql database of the html I am trying to display: </p>
<p><a href="http://www.yousendit.com/download/TTZueEVYQzMrV3hMWEE9PQ" rel="nofollow noreferrer">http://www.yousendit.com/download/TTZueEVYQzMrV3hMWEE9PQ</a> </p>
<p>it says utf-8 in the source. the actual page code generated from echoing out article_desc is here: </p>
<p><a href="http://www.nomorepasting.com/getpaste.php?pasteid=22566" rel="nofollow noreferrer">http://www.nomorepasting.com/getpaste.php?pasteid=22566</a> </p>
<p>it is definitely the same record, so I am unsure why it seems to very different.</p>
<p>edit: this was fixed by calling: mysql_query('SET NAMES utf8'); </p>

349,652 | <p>I'm getting a strange effect in Jena 2.5.5 (on Linux) where I am playing around with the inference API. The following code is a stripped down version. I am creating an initially empty Model and a generic rule reasoner. I add a reflexivity rule for a certain statement. I attach the reasoner to the model to get an InfModel. Then I create the matching statement and add it to the Model. </p>
<p>Result: InfModel contains both the statement and its reverse. So far so good, that's what it's supposed to do.</p>
<p>Now, when I <code>System.out.println()</code> the InfModel prior to adding the matching statement to Model, the result is completely different: the rule seems not to fire and thus, InfModel will end up not containing the reverse of the original statement.</p>
<p>How does writing the model to the console change the functionality of the code? Is this behavior documented?</p>
<pre><code>import java.util.*;
import com.hp.hpl.jena.rdf.model.*;
import com.hp.hpl.jena.reasoner.rulesys.*;
/**
* Describe class <code>RuleTest</code> here.
*/
public class RuleTest {
public static void main(String[] args) throws Exception {
/* create model */
Model model = ModelFactory.createDefaultModel();
/* output model */
System.out.println("original model : " + model);
System.out.println("-----");
/* collect rules */
List<Rule> rules = new ArrayList<Rule>();
Rule rule = Rule.parseRule("[ (subject predicate object) -> (object predicate subject) ].");
rules.add(rule);
/* create rule reasoner */
GenericRuleReasoner reasoner = new GenericRuleReasoner(rules);
/* attach reasoner to model */
InfModel infModel = ModelFactory.createInfModel(reasoner, model);
/* output model */
//-----------------------------------------------//
// commenting the following line in/out changes //
// the output of (*) below in Jena 2.5.5 ?!?!?! //
//-----------------------------------------------//
//System.out.println("inference model: " + infModel);
System.out.println("=====");
/* add facts to original model */
Resource s = model.createResource("subject");
Property p = model.createProperty("predicate");
RDFNode o = model.createResource("object");
Statement stmt = model.createStatement(s, p, o);
model.add(stmt);
/* output models */
System.out.println("original model : " + model);
System.out.println("-----");
System.out.println("inference model: " + infModel); // (*)
}

349,653 | <p>The following doesn't work, because it doesn't wait until the process is finished:</p>
<pre><code>import subprocess
p = subprocess.Popen('start /WAIT /B MOZILL~1.LNK', shell=True)
p.wait()
</code></pre>
<p>Any idea how to run a shortcut and wait that the subprocess returns ?</p>
<p><strong>Edit:</strong> originally I was trying this without the <strong>shell</strong> option in my post, which caused Popen to fail. In effect, <code>start</code> is not an executable but a shell command. This was fixed thanks to Jim.</p>

349,655 | <p>I've created a database in Visual Studio 2008 in an App_Data folder of a MVC Web Application project. This results in an mdf file for the database that can be explored in the Server Explorer tab. You can create a SQL script for changes you do to the database.</p>
<p>So I'm wondering how you run these sql change scripts to an mdf-file in Visual Studio 2008? Or am I forced to do this via the SQL Management Studio Express application?</p>

349,657 | <p>I have a problem. </p>
<p>I'm working on another guy's code and there is a JFrame with lots of JSeparators(he used them as borders for 'panels') now I'm replacing them for a JBorderedPanel class that follows the same border style of the whole application.</p>
<p>The problem is that some of his separators are not clear to determine where they are in the code, there are lots of jSeparator#, replace with for any number between 0 and 999.</p>
<p>Is there any way to determine which variable correspond to which border other than testing all jSeparators one by one?</p>
<p>In before 'Don't replace them!' I'm obligated to replace them. I wouldn't be doing this if I could.</p>
<p>Thanks in advance.</p>

349,659 | <h1>Duplicate from : <a href="https://stackoverflow.com/questions/16432/c-string-output-format-or-concat">String output: format or concat in C#?</a></h1>
<p>Especially in C# world using String.Format for everything is really common, normally as VB.NET developer unless I have to* I don't String.Format, </p>
<p>I prefer normal string concatenation, such as:</p>
<pre><code>V1 = V2 & "test-x" & V3 & "-;"
</code></pre>
<p>to me it's better than this:</p>
<pre><code>V1 = String.Format("{0} test-x {1} -;", V2, V3)
</code></pre>
<p>Am I missing something? Or is this just a personal preference?</p>
<p><strong>Reasons to Use String.Format (From The Answers)</strong> (<em>I'll try to keep this up to date</em>)</p>
<ul>
<li>Localization is so much easier if you use String Format</li>
<li>Obviously it's easier to change the format of input</li>
<li>It's more readable (<em>however this is personal</em>)</li>
<li>Better Performance </li>
</ul>
<p>**Sometimes I need to change the style or replacing stuff dynamically then I use String.Format*</p>

349,702 | <p>I'm trying to learn bash string handling.
How do I create a bash script which is equivalent to this Java code snippet?</p>
<pre><code>String symbols = "abcdefg12345_";
for (char i : symbols.toCharArray()) {
for (char j : symbols.toCharArray()) {
System.out.println(new StringBuffer().append(i).append(j));
}
}
</code></pre>
<p>The output of the above code snippet starts with:</p>
<pre><code>aa
ab
ac
ad
ae
af
</code></pre>
<p>And ends with:</p>
<pre><code>_g
_1
_2
_3
_4
_5
__
</code></pre>
<p>My goal is to have a list of allowed characters (not necessarily the ones above) and print out all the permutations of length 2. If it is possible I would like a solution which relies solely on bash and doesn't require anything else installed.</p>
<p><strong>Edit:</strong> Just a little follow up question: Is there a way to do this with a string without spaces separating sub-strings? Like LIST="abcdef12345_"?</p>

349,705 | <p>As in the subject, how can one get the total width of an element, including its border and padding, using jQuery? I've got the jQuery dimensions plugin, and running <code>.width()</code> on my <code>760px-wide</code>, <code>10px padding</code> DIV returns <code>760</code>.</p>
<p>Perhaps I'm doing something wrong, but if my element manifests itself as <code>780 pixels wide</code> and Firebug tells me that there's <code>10px padding</code> on it, but calling <code>.width()</code> only gives 760, I'd be hard pressed to see how.</p>
<p>Thanks for any suggestions.</p>

349,724 | <p>A recent <a href="https://stackoverflow.com/questions/349659/stringformat-or-not">question came up</a> about using String.Format(). Part of my answer included a suggestion to use StringBuilder.AppendLine(string.Format(...)). Jon Skeet suggested this was a bad example and proposed using a combination of AppendLine and AppendFormat.</p>
<p>It occurred to me I've never really settled myself into a "preferred" approach for using these methods. I think I might start using something like the following but am interested to know what other people use as a "best practice":</p>
<pre><code>sbuilder.AppendFormat("{0} line", "First").AppendLine();
sbuilder.AppendFormat("{0} line", "Second").AppendLine();
// as opposed to:
sbuilder.AppendLine( String.Format( "{0} line", "First"));
sbuilder.AppendLine( String.Format( "{0} line", "Second"));

<p>I would like to find them by their name in "Control Panel" -> "Network Connections". So, for example, if I have a VPN called "My Work" I would like to be able to find it using the name "My Work".</p>

How can I add a dictionary entry with single Vid and more than one PIDs? If I use CFDictionarySetValue with 2 PIDs, the 2nd Pid call overwrites the first dictionary value.

349,787 | <p>In a software-project written in java you often have resources, that are part of the project and should be included on the classpath. For instance some templates or images, that should be accessible through the classpath (getResource). These files should be included into a produced JAR-file.</p>
<p>It's clear that these resources should be added to the revision-control-system. But in which directory you put these files? Parallel to the java-source-files or in another directory that also reproduces the needed package-structure?</p>

349,802 | <p>Is it possible for me to create and destroy a TXMLDocument by myself in Borland C++ Builder? I've tried but borland keeps telling me that TXMLDocument is (and must be) an IDE managed component. </p>
<p>Also, the only reason that I want to do this is that TXMLDocument sort of crashes: I get the TXMLDocument and 'Gets' a workbook from it, sets some document properties (the xml is saved as an Excel-file later), and the I add some styles. Ok, then I add a worksheet and then all the cells that I want with proper formatting and then I save it. At this point everything is OK. </p>
<p>Then I want to save another Excel-file. Since the IDE doesn't let me delete and recreate the TXMLDocument I try to delete just the worksheet form it. When I try this (in debug mode) the IDE goes in to line step mode in the CPU tab (showing some assembler):</p>

349,842 | <p>I want to do some functional testing on a (restful) webservice. The testsuite contains a bunch of test cases, each of which performs a couple of HTTP requests on the webservice.</p>
<p>Naturally, the webservice has to run or the tests will fail. :-)</p>
<p>Starting the webservice takes a couple of minutes (it does some heavy data lifting), so I want to start it as infrequently as possible (at least all test cases that only GET resources from the service could share one).</p>
<p>So is there a way to do set up me the bomb in a test suite, before the tests are run like in a @BeforeClass method of a test case?</p>

349,845 | <p>Environment: Rails 2.2.2, Oracle 10g</p>
<p>Most of the columns declared "date" in my ActiveRecord models are exactly that: dates: they don't care about time at all.</p>
<p>So with a model declared thus:#</p>
<pre><code>class MyDateOnlyModel < ActiveRecord::Migration
def self.up
create_table :my_date_only_model do |t|
t.date :effective_date
t.timestamps
end
end
end
</code></pre>
<p>writing a test like this:</p>
<pre><code>test_date = Date.new(2008,12,05)
MyDateOnlyModel.create!(:effective_date => test_date)
assert_equal test_date, MyDateOnlyModel.find(:first).effective_date
</code></pre>
<p>should pass, shouldn't it? (Assuming I didn't mess anything up transcribing the above, of course)</p>
<p>But it doesn't - not quite. I get this:</p>
<pre><code><Fri, 05 Dec 2008> expected but was
<Fri, 05 Dec 2008 00:00:00 UTC +00:00>.
</code></pre>
<p>So I put a date into the database and got ... well what <em>did</em> I get?</p>
<pre><code>puts MyDateOnlyModel.find(:first).eff_date.class
</code></pre>
<p>tells me I actually got a <code>ActiveSupport::TimeWithZone</code>. Which wasn't what I wanted at all.</p>
<p>Is there a simple way to tell ActiveRecord that some (not all) columns are <code>Date</code>s and only <code>Date</code>s?</p>
<p>UPDATE: more complaining...</p>
<p>Yes, I could use to_date:</p>
<pre><code>assert_equal test_date, MyDateOnlyModel.find(:first).effective_date.to_date
</code></pre>
<p>works fine. But that's what I'm trying to avoid. I asked AR to make me a date, I want a date back.</p>
<p>And I could add a method to my class, effective_date_as_date - that works too. But surely it's not impossible to just get a date, dagnabbit.</p>
<p><strong>PRE-ACCEPTANCE UPDATE</strong></p>
<p>Eventually I realised why this was a particular problem with Oracle: there is no distinction between DATE and DATETIME, so ActiveRecord can't figure out unaided whether a time of zero means midnight (possibly with time zone corrections) or just the date. Bah. Stupid Oracle. So I'm going to have either to go down the plugin route, change my database (tempting, so very tempting) or continue with the to_date/to_time mess I have at present.</p>

349,852 | <p>I'm extracting an interface that I would like to retain the original name. The actual class will get a "Impl" suffix, in accordance with our naming conventions. I want to know how to best reflect that in subversion so that the history "AppPropertiesImpl.java" covers its life as "AppProperties.java". As for the new "AppProperties.java", I'm thinking it could be either a new file or a copy of the old. Any idea how to pull this off?</p>
<p>Here's what I have now:</p>
<p>AppProperties.java</p>
<pre><code>public class AppProperties {
public static final CONSTANT_ONE = "CONSTANT_ONE";
private String propertyOne;
public String getPropertyOne() {
return propertyOne;
}
public String setPropertyOne(String propertyOne) {
this.propertyOne = propertyOne;
}
}
</code></pre>
<p>And I want to end up with:</p>
<p>AppProperties.java</p>
<pre><code>public interface AppProperties {
public static final CONSTANT_ONE = "CONSTANT_ONE";
String getPropertyOne();
String setPropertyOne(String propertyOne);
}
</code></pre>
<p>AppPropertiesImpl.java</p>
<pre><code>public class AppPropertiesImpl implements AppProperties {
private String propertyOne;
public String getPropertyOne() {
return propertyOne;
}
public String setPropertyOne(String propertyOne) {
this.propertyOne;
}
}

349,858 | <p>I'm trying to get a UIDatePicker with a UIButton to show up in a UIActionSheet. Unfortunately it gets cropped off and the entire Date Picker is not visible. I have not even attempted to add the UIButton yet. Can anyone suggest on getting the entire view to fit properly? I'm not sure how to add the proper dimensions as UIActionSheet seems to lack an <code>-initWithFrame:</code> type constructor.</p>
<pre><code>UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"Date Picker"
delegate:self
cancelButtonTitle:@"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:nil];
// Add the picker
UIDatePicker *pickerView = [[UIDatePicker alloc] init];
pickerView.datePickerMode = UIDatePickerModeDate;
[menu addSubview:pickerView];
[menu showInView:self.view];
[pickerView release];
[menu release];
</code></pre>
<p>I've also tried with something similar to:</p>
<pre><code>UIActionSheet *menu = [[UIActionSheet alloc] initWithFrame:CGRectMake(200.0, 200.0, 100.0f, 100.0f)];
</code></pre>
<p>The coords are ofcourse not realistic, but they don't seem to affect the position/size of the UIActionSheet.</p>

349,861 | <p>I have a script that animates a small DIV popping up on the page. It all works fine in IE, and in FF if I remove the DOCTYPE, but when the DOCTYPE is XHTML/Transitional, in Firefox, the width does not change. </p>

alert("this.container.style.width before = " + this.container.style.width)
this.container.style.width = this.width;
alert("this.container.style.width after = " + this.container.style.width);
this.container.style.height = this.height;
</code></pre>
<p>In IE, and in FF with no DOCTYPE, the first alert says 0, and the second says 320 (which is the width set elsewhere in the code) </p>
<p>in FF, with the DOCTYPE to XHTML/Transitional, both alerts show 0. Any idea what's going on here? I'm thinking I may need to explicitly set positions on the DIVs in Transitional, but I'm not sure. </p>

349,878 | <p>OK since I am in a holding pattern on this issue perhaps someone has seen these symptoms and can provide some sage advice. (Note: I have learned only enough Active Directory information to build this feature and I only have read access to the Active Directory.)</p>
<p>I updated the company intranet to allow the automatic entry/modification of employee phone/address information; it uses a web service to connect to the company Active Directory so I can call it from multiple locations in the main application. </p>
<p>The AD has two domains (A and B) in the same forest. Each domain has an ‘ADS update user’ group and an ‘ADSupdate’ account (which belongs to ‘ADS update user’).</p>
<p>Problem: Entries in Domain A update fine for Local Development Servers, Test Servers, and Production Servers. Entries in Domain B update only when run from Local Development Servers. When you run the same code (verified multiple times) on either Test or Production you get a (General access denied error).</p>
<p>The domain name is stored in the employee record so the exact same code is called for all employees.</p>
<p>All Local Development Servers, Test, and Production servers reside in Domain A.</p>
<p>This has the Active Directory Admin for Domain B stumped and to be honest I am thankful that the Local Development Servers are able to update the Active Directory entries in domain B. It proves that the code works at least in one location</p>
<p>I have looked at machine permissions, permissions on the group and user, and IIS and I can spot no significant differences.
Any help would be appreciated…</p>

349,889 | <p>I just wrote the following C++ function to programmatically determine how much RAM a system has installed. It works, but it seems to me that there should be a simpler way to do this. Am I missing something?</p>
<pre><code>getRAM()
{
FILE* stream = popen("head -n1 /proc/meminfo", "r");
std::ostringstream output;
int bufsize = 128;
while( !feof(stream) && !ferror(stream))
{
char buf[bufsize];
int bytesRead = fread(buf, 1, bufsize, stream);
output.write(buf, bytesRead);
}
std::string result = output.str();
std::string label, ram;
std::istringstream iss(result);
iss >> label;
iss >> ram;
return ram;
}
</code></pre>
<p>First, I'm using <code>popen("head -n1 /proc/meminfo")</code> to get the first line of the meminfo file from the system. The output of that command looks like</p>
<blockquote>
<p>MemTotal: 775280 kB</p>
</blockquote>
<p>Once I've got that output in an <code>istringstream</code>, it's simple to tokenize it to get at the information I want. Is there a simpler way to read in the output of this command? Is there a standard C++ library call to read in the amount of system RAM?</p>

349,892 | <p>I have a logging table which has three columns. One column is a unique identifier, One Column is called "Name" and the other is "Status".<br>
Values in the Name column can repeat so that you might see Name "Joe" in multiple rows. Name "Joe" might have a row with a status "open", another row with a status "closed", another with "waiting" and maybe one for "hold". I would like to, using a defined precedence in this highest to lowest order:("Closed","Hold","Waiting" and "Open") pull the highest ranking row for each Name and ignore the others. Anyone know a simple way to do this? </p>
<p>BTW, not every Name will have all status representations, so "Joe" might only have a row for "waiting" and "hold", or maybe just "waiting".</p>

349,918 | <p>I am using a third-party DLL. For some particular cases, a function in the DLL is throwing an exception. Is it possible to debug the DLL in the Visual Studio?</p>
<p>After <a href="https://stackoverflow.com/questions/349918/debugging-a-third-party-dll-in-visual-studio/349925#349925">the answer from Andrew Rollings</a>, I am able to view the code, but is there any easy way to debug through the code in Visual Studio?</p>

349,927 | <p>According to <em>Cocoa Programming for Mac OS X, 3rd Edition</em>, on page 245 (chapter 17), you will usually create views in Interface Builder. However, it is possible to create them in code, a la:</p>
<pre><code>NSView *superview = [window contentView];
NSRect frame = NSMakeRect(10, 10, 200, 100);
NSButton *button = [[NSButton alloc] initWithFrame:frame];
[button setTitle:@"Click me!"];
[superview addSubview:button];
[button release];
</code></pre>
<p>That’s all well and good, but how would I wire up said control’s outlets to actions in code? (In .NET, this is an easy thing; add a delegate ... I’m hoping it’s similarly easy in Cocoa/Obj-C.)</p>

349,933 | <p>I have a user table like this</p>
<pre><code>user_id | community_id | registration_date
--------------------------------------------
1 | 1 | 2008-01-01
2 | 1 | 2008-05-01
3 | 2 | 2008-01-28
4 | 2 | 2008-07-22
5 | 3 | 2008-01-11
</code></pre>
<p>For each community, I would like to get the time that the 3rd user registered. I can easily do this for a single community using MySql's 'limit' SQL extension. For example, for community with ID=2</p>
<pre><code>select registration_date
from user
order by registration_date
where community_id = 2
limit 2, 1
</code></pre>
<p>Alternatively, I can get the date that the first user registered for all communities via:</p>
<pre><code>select community_id, min(registration_date)
from user
group by 1
</code></pre>
<p>But I can't figure out how to get the registration date of the 3rd user for <em>all</em> communities in a single SQL statement.</p>
<p>Cheers,
Don</p>

349,938 | <p>Is there a programmatic way to extract equations (and possibly images) from an MS Word document? I've googled all over, but have yet to find anything that I can sink my teeth into and work from. If possible, I'd like to be able to do this with VB.NET or C#, but I can pick up enough of any language to hack out a DLL. Thanks!</p>
<p><strong>EDIT:</strong> Right now I'm looking at extracting the equations from Word 2003, but if converting it to 2007/Open XML is required, that's fine.</p>

349,948 | <p>I had a class with some common error handling code, and I wanted to pass in the method and arguments to call, but I couldn't quite come up with the syntax. What I want to do is roughly this:</p>
<pre><code>private void InvokeHelper(Delegate method, params object[] args)
{
bool retry = false;
do
{
try
{
method.DynamicInvoke(args);
retry = false;
}
catch (MyException ex)
{
retry = HandleException(ex);
}
} while (retry);
}
</code></pre>
<p>and then be able to do things like:</p>
<pre><code>InvokeHelper(foo.MethodA, a, b, c);
InvokeHelper(foo.MethodB, x, y );
</code></pre>
<p>This gets a compiler error converting foo.MethodA and foo.MethodB into System.Delegate. I came up with the workaround below (and I actually like it better because then I get type checking on my arguments to my methods), but I'm curious if there's a way to do what I was originally trying to do? I know I could use <code>foo.GetType().GetMethod("MethodA")</code> and invoke that, but I was trying to avoid reflection. I mainly just want to understand how methods are dynamically invoked in .net.</p>
<p>Workaround:</p>
<pre><code>private delegate void EmptyDelegate();
private void InvokeHelper(EmptyDelegate method)
{
bool retry = false;
do
{
try
{
method.Invoke();
retry = false;
}
catch (MyException ex)
{
retry = HandleException(ex);
}
} while (retry);
}
</code></pre>
<p>then call:</p>
<pre><code>InvokeHelper(delegate() { foo.MethodA(a, b, c); });
InvokeHelper(delegate() { foo.MethodB(x, y); });
</code></pre>

349,951 | <p>We have a stored procedure that runs nightly that in turn kicks off a number of other procedures. Some of those procedures could logically be run in parallel with some of the others. </p>
<ul>
<li>How can I indicate to SQL Server whether a procedure should be run in parallel or serial — ie: kicked off of asynchronously or blocking? </li>
<li>What would be the implications of running them in parallel, keeping in mind that I've already determined that the processes won't be competing for table access or locks- just total disk io and memory. For the most part they don't even use the same tables.</li>
<li>Does it matter if some of those procedures are the <em>same</em> procedure, just with different parameters?</li>
<li>If I start a pair or procedures asynchronously, is there a good system in SQL Server to then wait for both of them to finish, or do I need to have each of them set a flag somewhere and check and poll the flag periodically using <code>WAITFOR DELAY</code>?</li>
</ul>
<p>At the moment we're still on SQL Server 2000.</p>
<p>As a side note, this matters because the main procedure is kicked off in response to the completion of a data dump into the server from a mainframe system. The mainframe dump takes all but about 2 hours each night, and we have no control over it. As a result, we're constantly trying to find ways to reduce processing times.</p>

349,957 | <p>I'm having an issue with an ObservableCollection getting new items but not reflecting those changes in a ListView. I have enough quirks in the way I'm implementing this that I'm having a hard time determining what the problem is.</p>
<p>My ObservableCollection is implemented thusly:</p>
<pre><code>public class MessageList : ObservableCollection<LobbyMessage>
{
public MessageList(): base()
{
Add(new LobbyMessage() { Name = "System", Message = "Welcome!" });
}
}
</code></pre>
<p>I store the collection in a static property (so that its easily accessible from multiple user controls):</p>
<pre><code>static public MessageList LobbyMessages { get; set; }
</code></pre>
<p>In the OnLoad event of my main NavigationWindow I have the following line:</p>
<pre><code>ChatHelper.LobbyMessages = new MessageList();
</code></pre>
<p>My XAML in the UserControl where the ListView is located reads as:</p>
<pre><code> <ListBox IsSynchronizedWithCurrentItem="True"
ItemsSource="{Binding Mode=OneWay}"
x:Name="ListBoxChatMessages"
d:UseSampleData="True"
ItemTemplate="{DynamicResource MessageListTemplate}"
IsEnabled="True">
<ListBox.DataContext>
<Magrathea_Words_Tools:MessageList/>
</ListBox.DataContext>
</ListBox>
</code></pre>
<p>The initial message that I added in the constructor appears in the UI just fine.</p>
<p>Now, the way I add new items to the collection is from a CallBack coming from a WCF service. I had this code working in a WinForms application and it was neccessary to marshall the callback to the UI thread so I left that code in place. Here is an abbreviated version of the method:</p>
<pre><code>Helper.Context = SynchronizationContext.Current;
#region IServiceMessageCallback Members
/// <summary>
/// Callback handler for when the service has a message for
/// this client
/// </summary>
/// <param name="serviceMessage"></param>
public void OnReceivedServiceMessage(ServiceMessage serviceMessage)
{
// This is being called from the WCF service on it's own thread so
// we have to marshall the call back to this thread.
SendOrPostCallback callback = delegate
{
switch (serviceMessage.MessageType)
{
case MessageType.ChatMessage:
ChatHelper.LobbyMessages.Add(
new LobbyMessage()
{
Name = serviceMessage.OriginatingPlayer.Name,
Message = serviceMessage.Message
});
break;
default:
break;
}
};
Helper.Context.Post(callback, null);
}
</code></pre>
<p>While debugging I can see the collection getting updated with messages from the service but the UI is not reflecting those additions.</p>
<p>Any ideas about what I'm missing to get the ListView to reflect those new items in the collection?</p>

349,978 | <p>I have just imported a WAR file from an external site, which is basically a servlet into Eclipse IDE (the project runs on Apache-Tomcat). </p>
<p>When I import it it has a folder called <strong>Web App Libraries</strong>. So here are a few of my newbie questions:</p>
<ol>
<li><p>I am unsure about what the exact purpose is of this folder is? What does it do, why would you choose to have it in your project? </p></li>
<li><p>I see that it has a folder called <strong>Improted Classes</strong> and foobar.class files inside it - why?<br>
<em>(These seemed to be mirrored in <strong>Web Content</strong> folder - although here you can modify the code as they are foobar.java.)</em></p></li>
<li><p>There are references to foobar.jar files too - these are also mirrored in <strong>WEB-INF/lib</strong> folder too - why?</p></li>
</ol>
<p>I know these are basic type questions but I'm just getting to grips with Java and website dev, so apologies if they sound a bit dumb! - BTW if anyone knows any good online resource to understand more about project file structures like this, then let me know. I just need to get to grips with this stuff asap - as the project deadline is fairly soon.</p>
<p>Cheers.</p>

350,081 | <p>In the application I'm working on porting to the web, we currently dynamically access different tables at runtime from run to run, based on a "template" string that is specified. I would like to move the burden of doing that back to the database now that we are moving to SQL server, so I don't have to mess with a dynamic GridView. I thought of writing a Table-valued UDF with a parameter for the table name and one for the query WHERE clause.</p>
<p>I entered the following for my UDF but obviously it doesn't work. Is there any way to take a varchar or string of some kind and get a table reference that can work in the FROM clause?</p>
<pre><code>CREATE FUNCTION TemplateSelector
(
@template varchar(40),
@code varchar(80)
)
RETURNS TABLE
AS
RETURN
(
SELECT * FROM @template WHERE ProductionCode = @code
)
</code></pre>
<p>Or some other way of getting a result set similar in concept to this. Basically all records in the table indicated by the varchar @template with the matching ProductionCode of the @code.</p>
<p>I get the error "Must declare the table variable "@template"", so SQL server probably things I'm trying to select from a table variable.</p>
<p>On Edit: Yeah I don't need to do it in a function, I can run Stored Procs, I've just not written any of them before.</p>

I am extending the Panel control and OnPreRender sticking some additional controls inside of it (lets just say 1 textbox for simplicity). From here I am just letting the Panels Render method do its thing. </p>
<p>The issue I am having is that obviously every time this control is rerendered it is just sticks that same TextBox in the panel again with the value I am coding in the OnPreRender method. Now I dont actually want to repopulate the panel every time, </p>
<p>I want to stick the textbox contorl in there on first load and have them reloaded from the control/viewstate caches. In this case with my example of just sticking a single textbox in the panel, if the value of the textbox changes and a postback occurs I want that value to to remain the changed value. </p>
<p>Really basic webforms stuff I know, but I have never had to create custom controls in my time. ANy help appreciated. </p>
<p>Chris. </p>

350,120 | <p>Does someone knows if it's possible to dynamically create a call chain and invoke it?</p>
<p>Lets say I have two classes A & B:</p>
<pre><code>public class A
public function Func() as B
return new B()
end function
end class
public class B
public function Name() as string
return "a string";
end function
end class
</code></pre>
<p>I want to be able to get <em>MethodInfo</em> for both <em>Func()</em> & <em>Name()</em> and invoke them dynamically so that I can get a call similar to <em>A.Func().Name()</em>.</p>
<p>I know I can use <em>Delegate.CreateDelegate</em> to create a delegate I can invoke from the two <em>MethodInfo</em> objects but this way I can only call the two functions separately and not as part of a call chain.</p>
<p>I would like two solutions one for .NET 3.5 using expression tree and if possible a solution that is .NET 2.0 compatible as well</p>

350,124 | <p>I'm looking to write an automated monitor script to programmatically retrieve information from another user's Exchange 2003 inbox. I have working C++ code to log into MAPI and connect to my own inbox. I can also use the Control Panel->Mail applet to configure another user's mailbox into my profile, and my code can access that way. However, this was done on my desktop with Outlook installed, which provides a richer mail profile editor.</p>
<p>Since this will run on a server, I'd prefer not to install Outlook at all. Instead, I can install the <a href="http://www.microsoft.com/downloads/details.aspx?familyid=E17E7F31-079A-43A9-BFF2-0A110307611E&displaylang=en" rel="nofollow noreferrer">MAPI client</a>. I then create a simple MAPI app that pops up the mail profile wizard using <code>MAPILogonEx()</code> with the <code>MAPI_LOGON_UI</code> flag. However, the basic MAPI client doesn't have the features to configure another user's mailbox. As a requirement, I can only run this script as the service account of the monitoring application, so I cannot tell it to run as the account whose mailbox I want.</p>
<p>Is it still possible to connect to another user's mailbox (assuming permissions are already granted) using the basic MAPI client? Or is it absolutely necessary to install Outlook for this functionality?</p>

350,140 | <p>So I'm basically a beginner when it comes to Vim, nonetheless I do know the basic things (open files, edit, move around, basic grep, .vimrc, etc)</p>
<p>I would submit this link first</p>
<p><a href="http://weblog.jamisbuck.org/2008/11/17/vim-follow-up" rel="nofollow noreferrer">http://weblog.jamisbuck.org/2008/11/17/vim-follow-up</a></p>
<p>If you scroll down to where it says "NERD___tree", it explains what it is and gives a link to the home page. I have already gotten NERD_tree installed, so far so good.</p>
<p>Only thing is, this guy (JamisBuck) adds a line to the .vimrc file to streamline it's usage (I'm guessing to toggle between NERD_tree and the actual file, because as far as I can tell, there is no quick way to do it other than typing in:</p>
<pre><code>:NERDTree
</code></pre>
<p>Every time which is less than desirable. The follwing is the code he adds to the .vimrc file:</p>
<pre><code>map <leader>d :execute 'NERDTreeToggle ' . getcwd()<CR>
</code></pre>
<p>He doesn't explain exactly what is is and/or how to use it, so If someone could give me a short explanation and/or point me towards a resource to learn more about this, that would be appreciated.</p>

350,150 | <p>I am trying to run some Perl CGI scripts under IIS. I get the following message :</p>
<pre>
<code>
CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are:
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LC_ALL = (unset),
LANG = (unset)
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
</code>
</pre>
<p>I found out that the problem occurs only when I "use" an internal library of ours but it's really a big one (using many other stuff) so I would prefer to know where to look. When I run the same script from the command line, the script runs just fine. I tried to set "LANG" to "C", then "LC_ALL" to "C" but it had no effect.</p>
<p>Any pointers welcome!</p>

350,181 | <p>What is the best was to evaluate an expression like the following:
<br />
(A And B) Or (A And C) Or (Not B And C)<br />
or<br />
(A && B) || (A && C) || (!B && C)<br /></p>
<p>At runtime, I was planning on converting the above expressions to the following:<br />
(True And False) Or (True And False) Or (Not False And True)<br />
or<br />
(True && False) || (True && False) || (! False && True)<br /></p>
<p>Conditions:
1) The logical expression is not known until runtime.
2) The number variable and their values are not known until runtime.
3) Variable values are never null.</p>
<p>I know I could create a simple assemble with a class and a method that I generate at runtime based on the inputs, but is there a better way.
I have done this before. Use a string builder to write the code, then call the compiler. After that, you load the assembly and call the method. </p>
<p>Suggestions?</p>
<p>Thanks.</p>

350,207 | <p>I have an ASP.NET page that uses a menu based on <code>asp:LinkButton</code> control in a Master page. When a user selects a menu item, an <code>onclick</code> handler calls a method in my C# code. The method it calls just does a <code>Server.Transfer()</code> to a new page. From what I have read, this is not supposed to change the URL displayed in the browser.</p>
<p>The problem is it that the URL changes in the browser as the user navigates the menu to different pages.</p>
<p>Here is an item in the menu:</p>
<pre><code><asp:LinkButton id="foo" runat="server" onclick="changeToHelp"><span>Help</span>
</asp:LinkButton>
</code></pre>
<p>In my C# code, I handle the event with a method like:</p>
<pre><code>protected void changeToHelp(object sender, EventArgs e)
{
Server.Transfer("Help.aspx");
}
</code></pre>
<p>Any ideas how I can navigate through the menu without the browser's URL bar changing?</p>

350,214 | <p>I have a ListBox whose ItemSource is an ObjectDataProvider that is an instance of an ObservableCollection. The ObservableCollection is a collection of ObservableCollections. The ItemTemplate of the ListBox is a DataTemplate that creates a ListBox for each item of the listbox. To illustrate this better I'm trying to recreate a card game in WPF. Basically, from a hand of cards you can create books. After you have a valid book, you can elect to make it a book which will go into the ObservableCollection of Books. The problem that I'm having is that each item of the ListBox is a ListBox that has an ItemSource that is a Book, that is an ObservableCollection of Cards. I don't think I'm having a problem with the source or the template of the outer ListBox, but I'm having a hard time understanding how I'm going to set the source of the ListBox items to the collection of cards for each book. Essentially, my question may be confusing and a difficult concept to grasp, but essentially I'm trying to figure out how to use a ListBox in a template that will be the template of another ListBox. If anyone has any idea of how to approach this, I would greatly appreciate hearing it.</p>

350,227 | <p>I've encountered a very strange bug in VBA and wondered if anyone could shed some light?</p>
<p>I'm calling a worksheet function like this: </p>
<pre><code>Dim lMyRow As Long
lMyRow = WorksheetFunction.Match(vItemID, rngMyRange.Columns(1), 0)
</code></pre>
<p>This is intended to get the row of the item I pass in. Under certain circumstances (although I can't pin down exactly when), odd things happen to the call to the Match function.</p>
<p>If I execute that line in the immediate window, I get the following:</p>
<pre><code>lMyRow = WorksheetFunction.Match(vItemID, rngMyRange.Columns(1), 0)
?lMyRow
10
</code></pre>
<p>i.e. the lookup works, and lMyRow gets a value assigned to it. If I let that statement execute in the actual code, I lMyRow gets a value of 0.</p>
<p>This seems very odd! I don't understand how executing something in the immediate window can succeed in assigning a value, where the same call, at the same point in program execution can give a value of 0 when it runs normally in code!</p>
<p>The only thing I can think of is that it's some odd casting thing, but I get the same behaviour taking if the variable to which I'm assigning is an int, a double, or even a string.</p>
<p>I don't even know where to begin with this - help!!</p>

<p>However, it doesn't detect a click and oddly enough the click event runs when the page loads.</p>
<p>The close button DOES however have a click event built in that closes the box, and I suspect my home-grown click event is being prevented somehow, but I can't figure it out.</p>

<pre><code>public School

publig String Name { get; set; }
public Address Address { get; set; }

public class Address

UpdateModel(school, form);
return new SchoolResponse() { School = school };
}
</code></pre>
<p>And the following form:</p>
<pre><code><form method="post">
School: <%= Html.TextBox("Name") %><br />
Street: <%= Html.TextBox("Address.Street") %><br />
City: <%= Html.TextBox("Address.City") %><br />
Zip Code: <%= Html.TextBox("Address.ZipCode") %><br />
Sate: <select id="Address.State"></select><br />
Country: <select id="Address.Country"></select><br />
</form>
</code></pre>
<p>I am able to update both the School instance and the Address member of the school. This is quite nice! Thank you ASP.NET MVC team!</p>
<p>However, how do I use jQuery to select the drop down list so that I can pre-fill it? I realize that I could do this server side but there will be other dynamic elements on the page that affect the list.</p>
<p>The following is what I have so far, and it does not work as the selectors don't seem to match the IDs:</p>
<pre><code>$(function() {
$.getJSON("/Location/GetCountryList", null, function(data) {
$("#Address.Country").fillSelect(data);
});
$("#Address.Country").change(function() {
$.getJSON("/Location/GetRegionsForCountry", { country: $(this).val() }, function(data) {
$("#Address.State").fillSelect(data);
});
});
});

350,308 | <p>I'm making a webpage with dynamic content that enters the view with AJAX polling. The page JS occasionally downloads updated information and renders it on the page while the user is reading other information. This sort of thing is costly to bandwidth and processing time. I would like to have the polling pause when the page is not being viewed.</p>
<p>I've noticed most of the webpages I have open spend the majority of their time minimized or in a nonviewed tab. I'd like to be able to pause the scripts until the page is actually being viewed.</p>
<p>I have no idea how to do it, and it seems to be trying to break out of the sandbox of the html DOM and reach into the user's system. It may be impossible, if the JS engine has no knowledge of its rendering environment. I've never even seen a different site do this (not that the user is intended to see it...)</p>
<p>So it makes for an interesting question for discussion, I think. How would you write a web app that is CPU heavy to pause when not being used? Giving the user a pause button is not reliable, I'd like it to be automatic.</p>

350,314 | <p>I have some XML in an XmlDocument, and I want to display it on an ASP.NET page. (The XML should be in a control; the page will have other content.) Right now, we're using the Xml control for that. Trouble is, the XML displays with no indentation. Ugly.</p>
<p>It appears that I'm supposed to create an XSLT for it, but that seems kind of boring. I'd rather just throw it into a control and have it automagically parse the XML and indent correctly. Is there an easy way to do that?</p>

350,318 | <p>I have a single large table which I would like to optimize.
I'm using MS-SQL 2005 server. I'll try to describe how it is used and if anyone has any suggestions I would appreciate it very much.</p>
<p>The table is about 400GB, has 100 million rows and 1 million rows are inserted each day.
The table has 8 columns, 1 data col and 7 columns used for lookups/ordering. </p>
<pre><code> k1 k2 k3 k4 k5 k6 k7 d1
</code></pre>
<p>where</p>
<pre><code> k1: varchar(3), primary key - clustered index, 10 possible values
k2: bigint, primary key - clustered index, total rows/10 possible values
k3: int, 10 possible values
k4: money, 100 possible values
k5: bool
k6: bool
k7: DateTime
</code></pre>
<p>Only one select query is run which looks like this:</p>
<pre><code> SELECT TOP(g) d1 FROM table WITH(NOLOCK)
WHERE k1 = a
AND k3 = c
AND k4 = d
AND k5 = e
AND k6 = f
ORDER BY k7
</code></pre>
<p>where g = circa 1 million
This query us ran about 10 times per day (often while inserts are happening) and takes about 5-30 minutes.</p>
<p>So I currently only have a clustered index on the two primary key columns. My question is: what indexes should I add to improve this query's performance?</p>
<p>Would separate indexes on every column be a good choice? I think a single index would take up about 5-8GB. The DB server has 8GB RAM total.</p>
<p>Please do not say that the best thing is to experiment. This is akin to 'I don't know, work it out your self' :)</p>
<p>Any tips much appreciated!</p>

<p>You've caused an outbreak of premature optimization here, if not outright suggestions that "the best thing is to experiment". You need to clarify a number of issues if you want useful help.</p>

EDIT: Comments on posts to date are now posted below along with query plan
- Mr. Flibble</p>
<hr>
<blockquote>
<p>You are probably I/O bound</p>
</blockquote>
<p>Yes, it is not CPU bound. Disk access is high. All available RAM seems to be used. Whether it is used wisely or not remains to be seen.</p>
<blockquote>
<p>You say you can't split the data because all the data is used: IMPOSSIBLE</p>
</blockquote>
<p>I mean that all data is used at some point - not that all data is used by each user in each query.
I can certainly split the data but, so far, I don't understand why partitioning the table is any better than using a clustered index.</p>
<blockquote>
<p>Why did you choose these types
VARCHAR probably should have been INT as it can only be a few values. The rest are sensible enough, Money represents a money value in real life and bigint is an ID, and the bools are onny, offy type things :)</p>
<p>By any chance we could get have a look the insert statement, or TSQL or the bulkinsert </p>
</blockquote>
<p>TSQL. Its basically INSERT INTO table VALUES (k1,k2,k3,k4,k5,k6,d1). The only thing that is in any way interesting is that many duplicate inserts are attempted and the k1 & k2 PK constraint is used to prevent duplicate data entering the database. I believed at design time (and now) that this was as quick a way as any to finter out duplicate data. </p>
<blockquote>
<p>Can you tell how often your insert happens
Every 10 minutes or so inserts run (ADO.NET) maybe 10K at a time and take a few minutes. I estimate currently a full day's inserts take 40% of the time in the day. </p>
<p>Does the DateTime field contains the date of insert
No. There is actually another DateTime column which does but it is not retrieved in any SELECT query so I didn't mention it for the sake of simplicity.</p>
<p>How did you came to this
More one man day thinking. </p>
<p>if you're interested only in the last data, deleting/archiving the useless data could make sense (start from scratch every morning)</p>
</blockquote>
<p>I am not interested in recent data only. A query may select some of the very first data that was inserted into the table all the way up to data inserted minutes ago. But as the data is filtered this does not mean that all the data in the DB is requested in that query.</p>
<blockquote>
<p>if there is only one "inserter" and only one "reader", you may want to switch to a specialised type (hashmap/list/deque/stack) or something more elaborated, in a programming language.</p>
</blockquote>
<p>I will probably stick with MSSQL for the moment. It's not broke yet, just a little slow.</p>
<p>liggett78, do you suggest a clustered index on columns k1,k4,k5,k6,k3 or a non-clustered index on those columns?</p>
<hr>
<p>My main question right now is should I extend the current clustered index to contain k4 also (this is the col with next most possible values) or should I just add a non-clustered index to k4.</p>
<p>Would adding all k1-k6 to a clustered index be an option? Then have a separate non-clustered index on the DateTime column for the ORDER BY? Am I correct in thinking that this would not cause any major increase in DB size but will only affect insert times. Can anyone guesstimate the effect this will have on inserts?</p>
<p>I think that if adding indexes to all the columns will double the DB size then it is not viable without large (ie. hardware) changes. </p>
<hr>
<p>The following plan was run with an index (non clustered) on the DATE column.</p>

350,323 | <p>I have a utility (grep) that gives me a list of filenames and a line numbers. After I have determined that devenv is the correct program to open a file, I would like to ensure that it is opened at the indicated line number. In emacs, this would be:</p>
<pre><code>emacs +140 filename.c
</code></pre>
<p>I have found nothing like this for Visual Studio (devenv). The closest I have found is:</p>
<pre><code>devenv /Command "Edit.Goto 140" filename.c
</code></pre>
<p>However, this makes a separate instance of devenv for each such file. I would rather have something that uses an existing instance.</p>
<p>These variations re-use an existing devenv, but don't go to the indicated line:</p>
<pre><code>devenv /Command "Edit.Goto 140" /Edit filename.c
devenv /Command /Edit filename.c "Edit.Goto 140"
</code></pre>
<p>I thought that using multiple "/Command" arguments might do it, but I probably don't have the right one because I either get errors or no response at all (other than opening an empty devenv).</p>
<p>I could write a special macro for devenv, but I would like this utility to be used by others that don't have that macro. And I'm not clear on how to invoke that macro with the "/Command" option.</p>
<p>Any ideas?</p>
<hr>
<p>Well, it doesn't appear that there is a way to do this as I wanted. Since it looks like I'll need to have dedicated code to start up Visual Studio, I've decided to use EnvDTE as shown below. Hopefully this will help somebody else.</p>
