Coding color scheme for programming in Windows, not just Visual Studio
===
Like many SO people, I'm in front of a computer almost all day. I like having a dark theme for Visual Studio (easier on the eyes), but since the rest of Windows and apps (explorer, dialogs, Outlook), have the full white background, it's even harder to switch between nice dark VS and sunshine bright Windows.
I tried a UXTheme.dll patch but couldn't find any dark themes that worked across Visual Studio and Windows apps in general. Any suggestions?
Edit: To be clear, I'd like no or almost no white. No scrollbars, menus, etc. | 0 | [

Why does Fiddler break my site's redirects!?
===
Why does using Fiddler break my site sometimes on page transitions.
After a server side redirect -- in the http response (as found in Fiddler) I get this:
<html><head><title>Object moved</title></head><body>
<h2>Object moved to <a href='/Accessories.aspx'>here</a>.</h2>
</body></html>
The site is an ASP.NET 1.1 / VB.NET 1.1 [sic] site.
Why doesnt Fiddler just go there for me? i dont get it.
I'm fine with this issue when developing but I'm worried that other proxy servers might cause this issue for 'real customers'. Im not even clear exactly what is going on. | 0 | [

What's the best C++ JSON parser?
===
I've seen the C++ JSON links on www.json.org but would like some feedback on which parser people prefer - for reliability, speed and ease of use.

How do you implement C#4's IDynamicObject interface?
===
To implement "method-missing"-semantics and such in C# 4.0, you have to implement IDynamicObject:
public interface IDynamicObject
{
MetaObject GetMetaObject(Expression parameter);
}
As far as I can figure out IDynamicObject is actually part of the DLR, so it is not new. But I have not been able to find much documentation on it.
There are some very simple example implementations out there (f.x. [here][1] and [here][2]), but could anyone point me to more complete implementations or some real documentation?
Especially, how exactly are you supposed to handle the "parameter"-parameter?

How do you implement search functionality using location information in ASP.NET?
===
I am currently looking into using Lucene.NET for powering the search functionality on a web application I am working on. However, the search functionality I am implementing not only needs to do full text searches, but also needs to rank the results by proximity to a specified address.
Can Lucene.NET handle this requirement? Or do I have need to implement some way of grouping hits into different locations (e.g. less than 5 miles, less than 10 miles, etc) first, then use Lucene.NET to rank the items within those groups? Or is there a completely different way that I am overlooking? | 0 | [

When I type uname -a, it gives the following output.
Linux mars 2.6.9-67.0.15.ELsmp #1 SMP Tue Apr 22 13:50:33 EDT 2008 i686 i686 i386 GNU/Linux
How can I know from this that the given OS is 32 bit or 64 bit?

Eclipse doesn't recognize XML
===
I'm using the PHP Eclipse.
When a XML file is opened, Eclipse doesn't seem to recognize the xml, meaning that all looks black.
When opened the XML file like "open with" and point to eclipse, it works fine.
What setting can be set to use that automatically so that eclipse recognizes it all the time?
Same goes for HTML files actually. | 0 | [

I'm rather confused about this.
And what's their relationship(e.g., how one can be used in the context of the other)? Much thanks!! | 0 | [

How does SQL know what @p# in LINQtoSQL queries?
===
I want to know how does the SQL Server know what @p# is in say this LINQtoSQL quey
SELECT [t0].[MemberID], [t0].[Aspnetusername], [t0].[Aspnetpassword], [t0].[EmailAddr], [t0].[DateCreated], [t0].[Location], [t0].[DaimokuGoal], [t0].[PreviewImageID], [t0].[LastDaimoku] AS [LastDaimoku], [t0].[LastNotefied] AS [LastNotefied], [t0].[LastActivityDate] AS [LastActivityDate], [t0].[IsActivated]
FROM [dbo].[Members] AS [t0]
INNER JOIN [dbo].[MemberStats] AS [t1] ON [t0].[MemberID] = [t1].[MemberID]
WHERE [t1].[TotalDeterminations] > @p0
When viewing SQLProfiler this is what gets executed against the database...but there is nothing telling SQL the value of @p0 so how does it know what that value is?

How to get common Subclasses of 2 Interfaces in Java with Eclipse?
===
Actually I try to find a subclass of InputStream which is also Serializable. I think that doesn't exist. Since both Interfaces have many sublclasses it is hard to find one that is a subclass of both.
Until now I haven't found anything to help my search in Eclipse. Anyone ideas? | 0 | [

"System.InvalidOperationException: The object is currently in use elsewhere" - how do I resolve this?
===
I got this error when trying to update an image.
It was a cross-thread update, but I used .Invoke(), so that shouldn't be the problem, should it. | 0 | [

How do you define a Single Responsibility?
===
I know about "class having a single reason to change". Now, what is that exactly? Are there some smells/signs that could tell that class does not have a single responsibility? Or could the real answer hide in YAGNI and only refactor to a single responsibility the first time your class changes? | 0 | [

Basic sample of a scriptable plugin for FireFox in C++ with VS2005/8
===
My experience to write a plugin for FireFox is below zero. Is someone out there who could point me to sample code on how to get this accomplished in C++ with VS2005/8?
What I need to do with JavaScript in the hosting html page is something like this:
var obj = document.getElementById("MyFFPlugin");
var value = obj.CalculateValue;
// Work with calculated value
Thanks!

How are Windows VK_ constants declared?
===
For example VK\_LEFT, VK\_DELETE, VK\_ESCAPE, VK\_RETURN, etc. How and where are they declared? Are they constants, #defines, or something else? Where do they come from?
If possible, please provide a file name/path where they are declared. Or some other info as specific as possible. | 0 | [

EBNF to fluent interface
===
I have recently had the need to write a fluent interface for C# that will essentially mirror SQL. Yes, I am aware of LINQ to SQL, but I'm interesting in getting "closer to the metal"--having something that essentially provides nothing more than an Intellisensified SQL shim *within* C#.
E.g.,
var fq = new FluentQuery();
Expression<Action> =
() => fq.SELECT.DISTINCT(Foo.ID).FROM(Foo).WHERE(Foo.Age > 22);
Now, I was thinking that this concept could be generalised--that is, how about a general EBNF to fluent interface generator? Does anyone know if such a beast exists?

What is the equivalent of .NET events in Ruby?
===
The problem is very simple. An object needs to notify some events that might be of interest to observers.
When I sat to validate a design that I cooked up now in Ruby just to validate it.. I find myself stumped as to how to implement the object events. In .Net this would be a one-liner.. .Net also does handler method signature verification,etc.
Is there an EventDispatcher module or something that I am missing that I can strap on to a Ruby class ? Hoping for an answer that plays along with Ruby's principle of least surprise.
*An event would be the name of the event plus a queue of [observer, methodName] objects that need to be invoked when the event takes place.* | 0 | [

How can I integrate Java with .Net?

I have one SDK that is available in Java and another SDK that is available for .Net and would like to write a single application that interfaces with both of them.

International Phone and Address Data?
===
I guess this is a multi-part question. I am building a membership site and want to have the accounts as international as possible.
1. What is the best way to collect phone numbers on a form that allows for international numbers? I'm not worried about storing them, just collection and validation. What I have now is a drop down with a country list that will add the country code, and then the number itself with validation for us/can/uk based on the country code, and then the extension. These will be stored as strings in 3 fields for cc/number/ext Does anyone have a better, solid solution for this, or perhaps seen one in action anywhere?
2. Ditto for addresses. What is the best way to go? Address/City/State/Zip/Country or just lines? I would like to be able to sort by these, so a single text field isn't a very good solution, though it is the most flexible.
This is also important because we may be sending actual mail to our members. I am put in mind of a few members I've had for other services that had addresses in countries I had never heard of, that even the woman at the post office couldn't tell if they were formatted correctly.
3. I want to have geodata in the db, at least country/state, for things like populating a state dropdown after selecting a country, field standardization, etc. Does anyone know of a great database that can be used as the geodata base of an app? | 0 | [

A good "About" dialog
===
Background: I have an application that is licensed under the LGPL which uses a whole bunch of open-source 3rd party libraries.
What kind of information should I have in my "About" dialog box. There are a few things I can think off the top:
- Author(s) of this application
- Copyright/Licensing information
- Credits
Is there anything else that should be in an About dialog? | 0 | [

Debugging .NET dynamic methods
===
We are using LINQ very widely in our system. Particularly LINQ-to-objects. So in some places we end up having a LINQ query in memory build up from some huge expressions. The problem comes when there's some bug in the expressions. So we get NullReferenceException and the stack trace leads us nowhere (to [Lightweight Function]). The exception was thrown inside the dynamic method generated by LINQ.
Is there any easy way to debug such dynamic methods? Or do I have to sacrifice myself to learning WinDBG? :-) | 0 | [

How do I make svnant/svnkit prompt for a username/password
===
I have an Ant script that needs to checkout a directory from Subversion. This works using svnant/svnkit. However, Subversion access is authenticated, and I do not want to store my user password in a file.
Can I make svnkit pop up a password dialog?
Or even better, make it use the same credential caching that subversive/svnkit inside of Eclipse uses (the username can be read from the build.properties)?
I cannot switch to public key based authentication, as I do not control the subversion server.

HTTP compliance testing

How do I set up a test project for a Eclipse plugin project
===
I'm working on a eclipse plug-in and I've tried to create another test project seperate from the plug-in. The reason I do this is to not let the plug-in depend on jUnit when it is exported. However, I can't access the Eclipse Plug-in API when I do the testing. Whenever I try to add Plug-in dependencies the import list to that is empty.
Does anyone know how to import Eclipse plug-in API to an existing project? The workspace layout looks like this at the moment:
+- com.foo.myplugin
| |
| +- JRE System Library
| |
| +- Plug-in Dependencies
| |
| +- src
| |
| +- icons, META-INF, plugin.xml, etc...
|
+- com.foo.myplugin.test
|
+- JRE System Library
|
+- JUnit 4
|
+- src | 0 | [

Web Services in Java
===
What do you usually use to connect to a Web Service when you are developing a Java project?
There are different API-s that can do the job.
From different books and tutorials I have read about: JAX-WS, JAXB, JAXM, JAXR, JAX-RPC, Axis ans so on.
I'm interested in what exactly are you using and how much? Take this as a survey if you wish :)

Size-to-content-layout problem in WPF
===
This is supposed to be a no brainer but I still can’t figure it out.
In my sample app there’s a **button** and a **textbox** in a **dockpanel**. If the content of the textbox is smaller than the content of the textbox the window is as big as it needs to be to display the content of the button. That’s what I want. But if I put more text into the textbox the window gets wider :-(
*The behavior I want is that the window gets the width according to the buttons content and the textbox wraps its content (or/and shows scrollbars if necessary).*
Thank you!
Some sample code:
<Window x:Class="SO1.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" SizeToContent="Width" FontSize="20">
<DockPanel>
<Button DockPanel.Dock="Top">A rather long text</Button>
<TextBlock TextWrapping="Wrap">Short text</TextBlock>
</DockPanel>
</Window>

Can I use the Python gettext module several times ?
===
Im a coding a library inluding textual feedback that I need to translate.
I put the following lines in a _config.py module that I import everywhere in my app :
import gettext, os, sys
pathname = os.path.dirname(sys.argv[0])
localdir = os.path.abspath(pathname) + "/locale"
gettext.install("messages", localdir)
I have the *.mo files in ./locale/lang_LANG/LC_MESSAGES and I apply the _() function to all the strings that need to be translated.
Now I just added a feature for the user, supposedly a programmer, to be able to create his own messages. I don't want him to care about the underlying implementation, so I want him to be apple to make it something straightforward like :
lib_object.message = "My message"
I used properties to make it clean, but what if my user whats to translate his own code (that uses mine) and does something like :
import gettext, os, sys
pathname = os.path.dirname(sys.argv[0])
localdir = os.path.abspath(pathname) + "/locale"
gettext.install("user_app", localdir)
lib_object.message = _("My message")
Is it a problem ? What can I do to avoid troubles without bothering my user ? | 0 | [

Group Similar Taskbar Buttons
===
Our app is made up of several Modules, and we would like to take advantage of the XP feature that would allow these to be grouped together. For example all windows in "Module A" would be grouped together, separately from windows in "Module B".
I've tried setting the AssemblyTitle attribute in the
project's AssemblyInfo.cs file but still no title appears, only the count of
the number of items.
Is there any way to have control over this, or is it all controlled by Windows?
This is in a WinForms application, for Windows XP.
Thanks

How do you balance Framework/API Design and TDD
===
We are building a framework that will be used by other developers and for now we have been using a lot of TDD practices. We have interfaces everywhere and have well-written unit tests that mock the interfaces.
However, we are now reaching the point where some of the properties/methods of the input classes need to be internal, and not visible to our framework users (for example object Id). The problem then is that we can't put those fields/methods on the interface as the interface does not describe accessibility.
We could:
1. Still use interfaces and upcast in the first line of the method, but that seems to defeat the purpose of interfaces.
2. Use classes as input parameters - breaking the TDD rule that *everything* should be interfaces
3. Provide another layer which does some translation between public interfaces and internal interfaces
Is there an existing pattern/approach to deal with this? What do the TDD people say should be done? | 0 | [

How to change the value of ${user} variable used in Eclipse templates
===
Instead of hardcoding the default @author template I would like Eclipse to use user's real name from taken from account information (in Linux - but M$Wndws solution is also welcome). Entering it somewhere into Eclipse configuration would be acceptable, too, alas I can't find the right place. | 0 | [

How do I round a number in javascript?
===
While working on a project, I came across a js-script created by a former employee that basically creates a report in the form of
Name : Value
Name2 : Value2
etc...
Problem for me though, is that the values can sometimes be floats (with different precision), integers, or even in the form "2.20011E+17"
What I outputted though are pure integers. I don't know a lot of javascript though.
How would I go about writing a method that takes these sometimes-floats and makes them integers? | 0 | [

How can I list files with their absolute path in linux?
===
I want to generate recursive file listings with full paths
/home/ken/foo/bar
but as far as I can see both ls and find only give relative path listings
./foo/bar (from the folder ken)
It seems like an obvious requirement but I can't see anything in the find or ls man pages.

Dot Matrix printing in C# ?
===
I'm trying to print to Dot Matrix printers (various models) out of C#, currently I'm using Win32 API (you can find alot of examples online) calls to send escape codes directly to the printer out of my C# application. This works great, but...
My problem is because I'm generating the escape codes and not relying on the windows print system the printouts can't be sent to any "normal" printers or to things like PDF print drivers. (This is now causing a problem as we're trying to use the application on a 2008 Terminal Server using Easy Print [Which is XPS based])
The question is:
How can I print formatted documents (invoices on pre-printed stationary) to Dot Matrix printers (Epson, Oki and Panasonic... various models) out of C# not using direct printing, escape codes etc. | 0 | [

What is the worst abuse you've seen of LINQ syntax?

On a recent [Dot Net Rocks podcast][1], Jon Skeet mentioned possible abuses of LINQ syntax. What examples have people seen where crazy things are being done with LINQ?

Problem ASP.NET Img tag
===
I have a problem with how ASP.Net generates the **img** tag.
I have a server control like this: ,<br>
asp:Image runat="server" ID="someWarning" ImageUrl="~/images/warning.gif" AlternateText="Warning" />
I expect it to generate this: <br>
img id="ctl00_ContentPlaceHolder1_ctl00_someWarning" src="../images/warning.gif" /> <br>
but instead it generates this:<br>
img alt="" src="/Image.ashx;img=%2fimages%2fwarning.gif"</img>
This give me errors when I execute the following js:
document.getElementById('ctl00_ContentPlaceHolder1_someWarning')
Any idea why it won't generate the expected html?
Thanks. | 0 | [

Two way data binding objects
===
I used an application recently that was awe inspiring. All the forms inherited from there own classes and a 'form' came with an amazing amount of functionality and looked the nuts.
What i'm interested in is this 'feature' of the form. This is a C# winforms project and blew me away.
The forms were bound to objects that the group had written to support two way data binding (to an extent). The way they behaved was pretty simple.
The data input forms all had controls that inherited from textbox and these were bound to properties of an object and entering data immediately validated it and the box was a light pink if validation failed and a light green if it passed. If the box ever turns blue this actually means the value in the database the form is bound to has changed and your changes to the controls were immediately saved when valid values entered. It was the case that some times a section of controls had to be filled before a save occured. But it was all automatic. You could stop at any point and come back later and continue without actually saving yourself.
And like I say if someone else is editing the same record values they change caused your textboxes to become blue and you knew you needed to reload the screen to see up to date information.
All of this came from using there own form class they had written and there own textbox controls bound to an objects property.
I'm mainly wondering how the hell did the object figure out the value had been changed by someone else. It surely isn't polling the database. This system was amazing. The brilliance didn't stop there.
For simplicity. How might I create an object or collection of objects to mimic the bahaviour. I'm not going to but I can't even see how.

I want to be able to run a function in my firefox sidebar js file when the selected tab in the main content window is reloaded or changed. So the sidebar can change depending on the site the user is looking at.

Modified files and git branches
===
I am working on a git repository with a master branch and another topic branch. I have switched to topic branch and modified a file. Now if I switched to master branch that same file is shown as modified.
For eg:
git status in git-build branch:
# On branch git-build
# Changes to be committed:
# (use "git reset HEAD <file>..." to unstage)
#
# modified: cvsup_current
#
Switch to master branch
[root@redbull builder_scripts (git-build)]# git co master
M builder_scripts/cvsup_current
Switched to branch "master"
git status in master branch
[root@redbull builder_scripts (master)]# git status
# On branch master
# Changes to be committed:
# (use "git reset HEAD <file>..." to unstage)
#
# modified: cvsup_current
#
Why is that the file is shown as modified in master branch though it was modified in git-build branch. My understanding was that the branches are independent of each other and when I change from one branch to another the changes do not "spill over" from one branch to another. So I am obviously missing some thing here.
Any one to help with a clue stick ?
regards,
raj

Is void** a acceptable type in ANSI-C
===
I have seen a function whose prototype is :
int myfunc(void** ppt)
This function is called in a C file as
a = myfunc(mystruct **var1);
where mystruct is typedef for one of structure we have.
This works wihtout any compilation errors in MSVC6.0, But when i compile it with some other C compiler, it gives an error at place where this function is called with error message:
**Argument of type mystruct ** is incompatible with parameter of type void \*\***
The argument of myfunc() is kept as void** because it seems to be a generic malloc kind of function to be called with various structure variable types for memory allocation
1.) Is there any type such as void ** allowed in C standard/any C compilers
2.)How do i fix this? [ I tried casting the function call argument to mystruct**, but didnt work]

div with id="end" on masterpage breaks .NET validation
===
*Quick info: I'm using latest release of .NET 2.0, and the following is a stripped down test page I wrote to reproduce the error.*
Excluding header bits, (there is no included/inline css or javascript) My content page looks like this:
<asp:Content ID="Content1" ContentPlaceHolderID="cphMain" runat="server">
<div>
<asp:ValidationSummary ID="ValidationSummary1" runat="server" />
<asp:TextBox ID="txtStuff" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="txtStuff" Display="None" ErrorMessage="need to fill it with words"> </asp:RequiredFieldValidator>
<asp:Button ID="bClick" runat="server" Text="Kerlick" />
</div>
</asp:Content>
My Master page (excluding header bits) looks like this:
<body>
<form runat="server" id="Form1">
<div>
<asp:ContentPlaceHolder ID="cphMain" runat="server">
</asp:ContentPlaceHolder>
</div>
<div id="end">
</div>
</form>
</body>
On clicking the button, the page throws an *"Microsoft JScript runtime error: Object doesn't support this property or method*" error, in **WebResource.axd** in the function
**ValidationSummaryOnSubmit(validationGroup)** (line 512).
Turns out, if I change the id of the div with **ID="end"** to something other than "end" it fixes the problem.
Now, I've fixed this problem, but I'm interested as to why this would break in the first place?
Is it possible that the validation summary renders a div with the same ID and is getting confused somewhere?

c++ dynamic_cast erorr handling
===
Is there any good practice related to dynamic_cast error handling (except not using it when you don't have to)? I'm wondering how should I go about NULL and bad_cast it can throw.
Should I check for both? And if I catch bad_cast or detect NULL I probably can't recover anyway...
For now, I'm using assert to check if dynamic_cast returned not NULL value. Would you accept this solution on a code review? | 0 | [

Is there a 'scratch pad' window in Visual Studio 2008
===
I currently use notepad to store little notes to myself about my code.
This is usually a mixture of code and requirements.
Is there a 'scratch pad' type window in VS2008 where i could do this.
The other alternative is to use code comment blocks in the source files, but that's not quite what I'm looking for. | 0 | [

Looking for a Report Designer that allows connection to a RESTful webservice
===
I'm looking for a Report Designer that will allow me to connect to a RESTful webservice. Ideally I would like one that has a royalty-free End-User Report Designer. WE will be hosting it in an ASP.NET web site. So something compatable with that would be ideal ;)
We used to use [Data Dynamics Active Reports][1]. However this doesn't allow connections to webservices.
Any help, very much appreciated.
Thanks in advance.

c++ class friend
===
I'm trying to compile such code:
#include <iostream>
using namespace std;
class CPosition
{
private:
int itsX,itsY;
public:
void Show();
void Set(int,int);
};
void CPosition::Set(int a, int b)
{
itsX=a;
itsY=b;
}
void CPosition::Show()
{
cout << "x:" << itsX << " y:" << itsY << endl;
}
class CCube
{
friend class CPosition;
private:
CPosition Position;
};
main()
{
CCube cube1;
cube1.Position.Show();
cube1.Position.Set(2,3);
cube1.Position.Show();
}
but get 'CCube::Position' is not accessible in function main() 3 times.
I want class CPosition to be declared outside CCube so that I can use it in future in new classes e.g. CBall :) but how can I make it work without using inheritance. Is it possible :)?
Regards,
PK

Are Open and Closed only relevant values of ConnectionState enumeration?
===
The [MSDN page][1] on ConnectionState enumeration says "This value is reserved for future versions of the product", for all values except Open and Closed. What thas that mean? Are other values even used?
However from this [StackOverflow answer][2] appears that ConnectionState.Broken is also used.

Retrieving the value of RETURN @@IDENTITY in C#
===
Here's a very simple question. I have an SP that inserts a row into a table and at the end there's the statement RETURN @@IDENTITY. What I can't seem to find is a way to retrieve this value in C#. I'm using the Enterprise library and using the method:
db.ExecuteNonQuery(cmd);
I've tried **cmd.Parameters[0].Value** to get the value but that returns 0 all the time. Any ideas? | 0 | [

WIX: How to Select Features From Command Line
===
This might be a naive question. I have to manually edit a .WXS file to make it support select features from command line.
For example, there are 3 features in .WXS file.
<Feature Id="AllFeature" Level='1'>
<Feature Id="Feature1" Level='1' > </Feature>
<Feature Id="Feature2" Level='1'> </Feature>
<Feature Id="Feature3" Level='1'> </Feature>
</Feature>
Now, I want to select features from command line. Say, if I type "msiexec /i install.msi FEATURE=A", then "Feature1" and "Feature2" is installed; if I type "msiexec/i install.msi FEATURE=B", then "Feature1" and "Feature3" is installed. In this case, "A" maps to Feature 1 and 2; "B" maps to Feature 1 and 3.
How to accomplish this in WIX?

How to build an iterative user defined action in Visual Buld Professional
===
In VBP its possible to define user defined actions by creating a custom COM component or a custom script.
I need to create an user defined action which is *iterative*, which means it has to call child steps in an iterative manner like the "process files" built in action does.
I can't figure out, how to to this and Google isn't helpful either. | 0 | [

time spent doing peer code reviews?

How much time do you spend doing peer code reviews?
Do you review everything?
I'm trying to push for more code reviews where I work at the moment and am trying to get a feel for what happens in the wider world. | 0 | [

What's the meaning of '&' and '!' before property name?
===
I am reading WIX script written by others. There are some code really confuses me.
<Custom Action='UnLoadSchedulerPerfCounters' After='InstallInitialize'><![CDATA[(Installed) AND (!Scheduler = 3)]]></Custom>
<Custom Action='RollbackSchedulerPerfCounters' After='WriteRegistryValues'><![CDATA[(&Scheduler = 3)]]></Custom>
So, what's the difference between "!Scheduler" and "&Scheduler"?
Is any special meaning when property is prefix-ed by "&" or "!"?

How to unit test IDisposable?
===
I'm working on a piece of library code around `IDisposable`. The managed path (via `using`) is easily testable. I'm wondering about the finalizer though: Is calling [`System.GC.Collect()`][1] sufficient to force the finalizer to run?

How to manage full screen in IE via automation? (Flash player like)
===
I'm facing a problem with IE7 full screen mode.
Got an app lying in an activeX embedded in IE. Until IE6, we managed fullscreen via
> IWebBrowser2::put_FullScreen(bool bIsFull)
which was good and well.
But since IE7, it seems that this trick is deprecated, as it looses the tab bar on the way back from fullscreen.
One solution would be to go with the call to
> IWebBrowser2::put_TheaterMode(bool bIsFull)
which seems to be what's done in IE7 when stroking F11
But that's not what I want, since there's the tab and address bar in auto hide mode
So I'd like to achieve a true fullscreen mode, like what's done in flash for fullscreen youtube videos.
Do you know any way to achieve that?

How do I programmatically (in vbscript) change/set the tcp port for a site under IIS?
===
My programming environment includes scripts for setting up my autobuild on a clean machine.
One step uses a vbscript to configure a website on IIS that is used to monitor the build.
On a particular machine I will be running apache on port 80 for a separate task.
I would like my vbscript to set the port to 8080 for the new site that it is adding.
How can I do this?

Web service object creation in JAX-WS RI
===
When I annotate a Java class with "@WebService" and use it with JAX-WS RI ("Metro"), how many objects of my class does the JAX-WS RI create? Is there only one object at all times or (perhaps depending on usage) can there be more instances be created? | 0 | [

How to do a check before allowing editing of a given row in a JTable
===
The problem is quite basic. I have a JTable showing cached data from a database. If a user clicks in a cell for editing, I want to attempt a lock on that row in the database. If the lock does not succeed, I want to prevent editing.
But I can't seem to find any clean way to accomplish this. Am I missing something? | 0 | [

Run index.php rather than listing files
===
I have recently reinstalled MacOSX and at some point (without realising it) I made it so that a directory without index.html would try instead to run index.php, this has since stopped happening. My localhost runs .php files fine, it just doesn't do so unless you specifically tell it to.
There are lots of htaccess guides online but I can't actually find one that tells me how to solve this problem :s

Symfony app - how to add calculated fields to Propel objects?
===
What is the best way of working with calculated fields of Propel objects?
Say I have an object "Customer" that has a corresponding table "customers" and each column corresponds to an attribute of my object. What I would like to do is: add a calculated attribute "Number of completed orders" to my object when using it on View A but not on Views B and C.
The calculated attribute is a COUNT() of "Order" objects linked to my "Customer" object via ID.
What I can do now is to first select all Customer objects, then iteratively count Orders for all of them, but I'd think doing it in a single query would improve performance. But I cannot properly "hydrate" my Propel object since it does not contain the definition of the calculated field(s).
How would you approach it? | 0 | [

Database tables / fields you always use in your killer apps
===
I'm hoping to tap into some collective experience here, so **What (if any) utility tables, or common fields do you always include in your database design?**
An example is that I always include an `App_Errors` table to store any uncaught exception information in, and an `App_Audit` table which stores all the edit information.
I've mooted (in my own mind) the benefit of including `RecordCreatedDate` and `RecordLastEditedDate` on each data table but not come to any conclusion as to whether or not the information really will be that useful.
To give the question a bit more direction - My current focus is globally accessible web application ( think social networking ).

HTML: What is the reason for embedded audio to be not always played?
===
I'm expiriencing some strange behavior of embedded audio (wav file) on HTML page.
I've got a page `https://server.com/listen-to-sound`, and a Wav file embedded in it via `<EMBED/>` tag, like this:
<embed src='https://server.com/path-to-sound' hidden="true" autostart="true" />
The page `https://server.com/listen-to-sound` is opened in IE 6 SP3 on machine#1 - the sound is played in the headphones.
The same page is opened on another machine(#2), with **exactly** same IE 6 SP3 version, privacy and proxy settings - there's no sound.
Totally, from 6 machines the sound is played on 2 and not played on 4. From these 4 machines, when the page `https://server.com/listen-to-sound` is opened in Opera, the sound is played.
I've triple-checked headphone connections, volume settings and other possible hardware and software driver issues: the problem is defenitely in IE settings.
I've also checked `https://server.com/path.to.sound` URL - the 4 machies that do not play sound fail to open this link, failing with an error like "Failed to download page".
Cleaning IE caches, temporary internet files, SSL Servificates caches did not solve the problem also.
Googling gave me nothing special but old Flash trick to use `<OBJECT>` tag and `<EMBED>` tag to be written in Object's comments.
Could the community please advice, what have I missed?
Have you expirienced such or related problems? How were they solved?
Do you have any suggestions on where the trick is?
Do you know some IE "features" that might affect execution(playing, showing) of embedded objects?
Thank you all in advance for answers and suggestions.

create std::string from char* in a safe way
===
I have a char* p, which points to a 0-terminated string.
How do I create a C++ string from it in an exception-safe way?
Here is an unsafe version:
string foo()
{
char *p = get_string();
string str( p );
free( p );
return str;
}
An obvious solution would be to try-catch - any easier ways? | 0 | [

ISO Country/Currency data
===
All,
Our application requires data on ISO countries and currencies (where the data must be up to date). We did purchase country/currency data from ISO themselves, however we still needed to perform alot of manual manipulation of the data, as well as write our own tool to read and process the data into our database.
1. Are we going about getting this data the wrong way?
2. What is the norm in relation to the acquisition of country/currency data?
3. Is there any well known providers out there that are offer to provide this data as a service or through some other medium in a usable format?
Any help will be greatly appreciated. | 0 | [

Should you make a self-referencing table column a foreign key?
===
For example to create a hierarchy of categories you use a column 'parent_id', which points to another category in the same table.
Should this be a foreign key? What would the dis/advantages be?

What mutation-testing frameworks exists?
===
In another [question][1] I asked if [mutation-testing][2] is useful in practice. As I didn't get answers that satisfy me, I want to check the current tools myself. So I need an overview about current existing mutation-test-frameworks. Which of them are most usable and why?
* I program in Java, so I would prefer Java-tools, but I would risk a look at interesting frameworks for different languages.
* I want to integrate in an automatic build-process, so I would prefer tools, that can be executed through command-line.

Creating a DateTime in a specific Time Zone in c# fx 3.5
===
I'm trying to create a unit test to test the case for when the timezone changes on a machine because it has been incorrectly set and then corrected.
In the test I need to be able to create DateTime objects in a none local time zone to ensure that people running the test can do so successfully irrespective of where they are located.
From what I can see from the DateTime constructor I can set the TimeZone to be either the local timezone, the UTC timezone or not specified.
How do I create a DateTime with a specific timezone like PST? | 0 | [

Database Guy Asks: Object-Oriented Design Theory?
===
I've worked with designing databases for a loooong time, and these days I'm working in C# too. OO makes sense to me, but I don't feel that I have a good grounding in the deep theory of OO design.
In database land, there's a lot of theory around how to design the structure of a database, the main notion being normalisation.
Are there any similar concepts behind how to design the structure of an Object-Oriented program?
Where can I look to find out more?
Is there a go-to work I should read?

How do you generate rDoc for a particular plugin using rake
===
OK, I am trying to generate the rDoc for paperclip, but the rake task is choking on another plugin before it gets to it, so this is out of the question:
rake doc:plugins
I could go and fix up the broken plugin, but I'm busy and lazy, so I just want to generate the docs for paperclip. Is there any way of doing this? | 0 | [

The DrawItem() method is performed repeatedly
===
I used the owner-drawn strategy on CMyListBox class which derives from CListBox. I only want the DrawItem() method to perform when I insert an item in the listbox. But the method is invoked many times. How can I change to invoke it whenever I need. | 0 | [

How do I find a user's Active Directory display name in a c# web application??
===
I'm writing a web application which uses windows authentication and I can happily get the user's login name using something like:
string login = User.Identity.Name.ToString();
But I don't need their login name I want their DisplayName. I've been banging my head for a couple hours now....
Can I access my organisation's AD via a web application?

Keeping a "reference" to a row object for a long time
===
In my application I keep a LINQ object fetched from the database, and regularly modifies it followed by `db.SubmitChanges()`.
I have read that you are not supposed to keep around the `DataContext` object for a long time.
But if I close my `DataContext` between modifications, I guess the data object loses its link to the actual database row.
What is the best alternative to keeping the DataContext open? Do I really have to reload the row every time I want to update it?
