Here's what I did:
```
<link rel="Stylesheet" type="text/css" href="Stylesheet.css" id="style" runat="server" visible="false" />
```
It fools Visual Studio into thinking you've added a stylesheet to the page but it doesn't get rendered.
---
Here's an even more concise way to do this with multiple references;
```
<% if (false) { %>
<link rel="Stylesheet" type="text/css" href="Stylesheet.css" />
<script type="text/javascript" src="js/jquery-1.2.6.js" />
<% } %>
```

I have an html file with an unordered list. I want to show the list items horizontally but still keep the bullets. No matter what I try, whenever I set the style to inline to meet the horizontal requirement I can't get the bullets to display.
The best option I saw in other answers was to use `float:left;`. Unfortunately, it doesn't work in IE7 which is a requirement here\* — you still lose the bullet. I'm not really keen on using a background image either.
What I'm gonna do instead (that no one else suggested, hence the self-answer) is go with manually | [

adding `•` to the my html, rather than styling this. It's less than ideal, but it's the most compatible option I found.

Is anyone using Elmah to send exceptions via email? I've got Elmah logging set up via SQL Server, and can view the errors page via the Elmah.axd page, but I am unable to get the email component working. The idea here is to get the email notification so we can react more quickly to exceptions. Here is my web.config (unnecessary sectionss omitted), with all the sensitive data replaced by \* \* \*. Even though I am specifying a server to connect to, does the SMTP service need to be running on the local machine?

Given a Python object of any kind, is there an easy way to get the list of all methods that this object has?
Or,
if this is not possible, is there at least an easy way to check if it has a particular method other than simply checking if an error occurs when the method is called?
**For many objects**, you can use this code, replacing 'object' with the object you're interested in:
```py
object_methods = [method_name for method_name in dir(object)
if callable(getattr(object, method_name))]
```

Despite primarily being a windows user, I am a huge fan of rsync. Now, I don't want to argue the virtues of rsync vs any other tool...this is not my point.
The only way I've ever found of running rsync on windows is via a version that is built to run on top of Cygwin, and as Cygwin has issues with Unicode, so does rsync.
Is anyone familiar enough with the workings of rsync to say if there are any real technical programming hurdles to porting rsync to a native Win32 binary?

Partly I ask because I'm am considering trying to take on the task of starting a port, but I want to make sure there's not something I'm missing in terms of why it may not be possible.

Will limiting a query to one result record, improve performance in a large(ish) MySQL table if the table only has one matching result?
for example
```
select * from people where name = "Re0sless" limit 1
```
if there is only one record with that name? and what about if `name` was the primary key/ set to unique? and is it worth updating the query or will the gain be minimal?
If the column has
**a unique index: no,** it's no faster
**a non-unique index: maybe,** because it will prevent sending any additional rows beyond the first matched, if any exist
**no index: sometimes**

We have a few very large Excel workbooks (dozens of tabs, over a MB each, very complex calculations) with many dozens, perhaps hundreds of formulas that use the dreaded INDIRECT function. These formulas are spread out throughout the workbook, and target several tables of data to look-up for values.
Now I need to move the ranges of data that are targeted by these formulas to a different location in the same workbook.

When writing multithreaded applications, one of the most common problems experienced is race conditions.
My questions to the community are:
* What is the race condition?
* How do you detect them?
* How do you handle them?
* Finally, how do you prevent them from occurring?
A race condition occurs when two or more threads can access shared data and they try to change it at the same time. Because the thread scheduling algorithm can swap between threads at any time, you don't know the order in which the threads will attempt to access the shared data. Therefore, the result of the change in data | [

is dependent on the thread scheduling algorithm, i.e. both threads are "racing" to access/change the data.
Problems often occur when one thread does a "check-then-act" (e.g. "check" if the value is X, then "act" to do something that depends on the value being X) and another thread does something to the value in between the "check" and the "act". E.g:
```
if (x == 5) // The "Check"
{
y = x * 2; // The "Act"
// If another thread changed x in between "if (x == 5)" and "y = x * 2" above,

y will not be equal to 10.
}
```
The point being, y could be 10, or it could be anything, depending on whether another thread changed x in between the check and act. You have no real way of knowing.
In order to prevent race conditions from occurring, you would typically put a lock around the shared data to ensure only one thread can access the data at a time. This would mean something like this:
```
// Obtain lock for x
if (x == 5)
{
y = x * 2; // Now, nothing can change x until the lock is released. | [

How do I use JUnit to test a class that has internal private methods, fields or nested classes?
It seems bad to change the access modifier for a method just to be able to run a test.
If you have somewhat of a legacy **Java** application, and you're not allowed to change the visibility of your methods, the best way to test private methods is to use [reflection](http://en.wikipedia.org/wiki/Reflection_%28computer_programming%29).
Internally we're using helpers to get/set `private` and `private static` variables as well as invoke `private` and `private static` methods. The following patterns will let you do pretty much anything related to the private methods | [

and fields. Of course, you can't change `private static final` variables through reflection.
```
Method method = TargetClass.getDeclaredMethod(methodName, argClasses);
method.setAccessible(true);
return method.invoke(targetObject, argObjects);
```
And for fields:
```
Field field = TargetClass.getDeclaredField(fieldName);
field.setAccessible(true);
field.set(object, value);
```

I would like to have an `iframe` take as much vertical space as it needs to display its content and not display a scrollbar. Is it at all possible ?
Are there any workarounds?
This should set the `IFRAME` height to its content's height:
```
<script type="text/javascript">
the_height = document.getElementById('the_iframe').contentWindow.document.body.scrollHeight;
document.getElementById('the_iframe').height = the_height;

You may want to add `scrolling="no"` to your `IFRAME` to turn off the scrollbars.

I have a recursive algorithm which steps through a string, character by character, and parses it to create a tree-like structure. I want to be able to keep track of the character index the parser is currently at (for error messages as much as anything else) but am not keen on implementing something like a tuple to handle multiple returned types.

Is there a way to get something similar to work which won't pollute my code?
Since you've already discovered the pseudo-mutable integer "hack," how about this option:
Does it make sense for you to make a separate Parser class? If you do this, you can store the current state in a member variable. You probably need to think about how you're going to handle any thread safety issues, and it might be overkill for this particular application, but it might work for you. | [

You can use a standard dot notation or a method call in Objective-C to access a property of an object in Objective-C.
```
myObject.property = YES;
```
or
```
[myObject setProperty:YES];
```
Is there a difference in performance (in terms of accessing the property)? Is it just a matter of preference in terms of coding style?
Dot notation for property access in Objective-C **is** a message send, just as bracket notation. That is, given this:
```
@interface Foo : NSObject
@property BOOL bar;
@end
Foo *foo = [[Foo alloc] init];
foo.bar = YES;
[foo setBar:YES];
```

When I try to do any svn command and supply the `--username` and/or `--password` options, it prompts me for my password anyways, and always will attempt to use my current user instead of the one specified by `--username`. Neither `--no-auth-cache` nor `--non-interactive` have any effect on this. This is a problem because I'm trying to call svn commands from a script, and I can't have it show the prompt.
For example, logged in as user1:
```
# $ svn update --username 'user2' --password 'password'
# user1@domain.com's password:
```
Other options work correctly:
```
# $ svn --version --quiet
# 1.3.2
```
Why does it prompt me?
And why is | [

it asking for user1's password instead of user2's?
I'm 99% sure all of my permissions are set correctly. Is there some config option for svn that switches off command-line passwords?
Or is it something else entirely?
I'm running svn 1.3.2 (r19776) on Fedora Core 5 (Bordeaux).

The prompt you're getting doesn't look like Subversion asking you for a password, it looks like ssh asking for a password. So my guess is that you have checked out an svn+ssh:// checkout, not an svn:// or http:// or https:// checkout.
IIRC all the options you're trying only work for the svn/http/https checkouts. Can you run svn info to confirm what kind of repository you are using ?
If you are using ssh, you should set up key-based authentication so that your scripts will work without prompting for a password. | [

We have an application with a good amount of jQuery JSON calls to server side code. Because of this, we have a large amount of binding code to parse responses and bind the appropriate values to the form. This is a two part question.
1. What is the reccomended approach for dealing with a large number of forms that all have different data. Right now were are trying to take a structured approach in setting up a js "class" for each page, with an init, wireClickEvents etc.. to try to have everything conformed.

jQuery code or any type of reccomended structure other than just throwing a bunch of functions in a js file?
Not 100% sure example what you are asking, but personally, and I use MochiKit, I create JavaScript "classes" (or widgets, if you prefer) for every significant client-side UI structure. These know, of course, how to populate themselves with data.
I don't know what more there is to say - writing UI code for the browser in JavaScript is no different than writing UI code for other types of apps, as far as I am concerned. Build classes and instantiate them as needed, | [

I have some UI in VB 2005 that looks great in XP Style, but goes hideous in Classic Style.
Any ideas about how to detect which mode the user is in and re-format the forms on the fly?

Post Answer Edit:
Thanks Daniel, looks like this will work. I'm using the first solution you posted with the GetCurrentThemeName() function.
I'm doing the following:
**Function Declaration:**
```
Private Declare Unicode Function GetCurrentThemeName Lib "uxtheme" (ByVal stringThemeName As System.Text.StringBuilder, ByVal lengthThemeName As Integer, ByVal stringColorName As System.Text.StringBuilder, ByVal lengthColorName As Integer, ByVal stringSizeName As System.Text.StringBuilder, ByVal lengthSizeName As Integer) As Int32

New System.Text.StringBuilder(260)
Dim stringSizeName As New System.Text.StringBuilder(260)
```
GetCurrentThemeName(stringThemeName, 260, stringColorName, 260, stringSizeName, 260)
MsgBox(stringThemeName.ToString)
The MessageBox comes up Empty when i'm in Windows Classic Style/theme, and Comes up with "C:\WINDOWS\resources\Themes\luna\luna.msstyles" if it's in Windows XP style/theme. I'll have to do a little more checking to see what happens if the user sets another theme than these two, but shouldn't be a big issue.
Try using a combination of [GetCurrentThemeName](http://www.pinvoke.net/default.aspx/uxtheme/GetCurrentThemeName.html) ([MSDN Page](http://msdn.microsoft.com/en-us/library/bb773365%28VS.85%29.aspx)) and [DwmIsCompositionEnabled](http://msdn.microsoft.com/en-us/library/aa969518%28VS.85%29.aspx)
I linked the first to PInvoke so you can just drop it in your code, and for the second one you can use the code provided in the MSDN comment:

What is a good setup for .hgignore file when working with Visual Studio 2008?
I mostly develop on my own, only occasionly I clone the repository for somebody else to work on it.
I'm thinking about obj folders, .suo, .sln, .user files etc.. Can they just be included or are there file I shouldn't include?
Thanks!
p.s.: at the moment I do the following : ignore all .pdb files and all obj folders.
```
# regexp syntax.
syntax: glob
*.pdb
syntax: regexp
/obj/

which has a function assigned.
Having said that, my problem has nothing to do with it, it's a generic class design issue.
I want to provide an abstract method in my base RoleProvider class to create the function (and persist it), but I want to make it optional to save a description for that function, so I need to create my CreateFunction method with an overload, one signature accepting the name, and the other accepting the name and the description.
I can think of the following scenarios:
1. Create both signatures with the abstract modifier. This has the problem that | [

the implementer may not respect the best practice that says that one overload should call the other one with the parameters normalized, and the logic should only be in the final one (the one with all the parameters). Besides, it's not nice to require both methods to be implemented by the developer.
2. Create the first like virtual, and the second like abstract. Call the second from the first, allow the implementer to override the behavior. It has the same problem, the implementer could make "bad decisions" when overriding it.
3. Same as before, but do not allow the first to be | [

overriden (remove the virtual modifier). The problem here is that the implementer has to be aware that the method could be called with a null description and has to handle that situation.
I think the best option is the third one...
How is this scenario handled in general? When you design an abstract class and it contains overloaded methods. It isn't that uncommon I think...
I feel the best combination of DRYness and forcing the contract is as follows (in pseudocode):

public final constructor(name) {
constructor(name, null)

User equals untrustworthy. Never trust untrustworthy user's input. I get that. However, I am wondering when the best time to sanitize input is. For example, do you blindly store user input and then sanitize it whenever it is accessed/used, or do you sanitize the input immediately and then store this "cleaned" version? Maybe there are also some other approaches I haven't though of in addition to these. I am leaning more towards the first method, because any data that came from user input must still be approached cautiously, where the "cleaned" data might still unknowingly or accidentally be dangerous.

way, what method do people think is best, and for what reasons?
I like to sanitize it as early as possible, which means the sanitizing happens when the user tries to enter in invalid data. If there's a TextBox for their age, and they type in anything other that a number, I don't let the keypress for the letter go through.
Then, whatever is reading the data (often a server) I do a sanity check when I read in the data, just to make sure that nothing slips in due to a more determined user (such as hand-editing files, or even modifying | [

What is the best way to create a lock on a file in Perl?
Is it best to flock on the file or to create a lock file to place a lock on and check for a lock on the lock file?
If you end up using flock, here's some code to do it:

use Fcntl ':flock'; # Import LOCK_* constants
# We will use this file path in error messages and function calls.
# Don't type it out more than once in your code. Use a variable.

Is it possible to do 3.1 or 5.1 audio using Flash? We're starting a project here for an interactive kiosk, and we've been told to use Flash. However, we also have a requirement to support either 3.1 or 5.1 audio (where 5.1 is the most wanted feature).
I haven't done any high-tech audio stuff using Flash, so I was wondering if anyone knew if it was possible to do?

I also found this blog entry from Summit Projects <http://summitprojectsflashblog.wordpress.com/2008/08/07/wave-theory-in-actionscript-3-part-4/> where they go into great detail about byte handling and processing audio samples. I'm not sure if they are using their own actionscript libraries for this, or if they are using Adobe's libraries. I'm not too up to speed on the audio side of Flash with respects to surround sound.

When building projects in C++, I've found debugging linking errors to be tricky, especially when picking up other people's code. What strategies do people use for debugging and fixing linking errors?
Not sure what your level of expertise is, but here are the basics.
Below is a linker error from VS 2005 - yes, it's a giant mess if you're not familiar with it.
```
ByteComparator.obj : error LNK2019: unresolved external symbol "int __cdecl does_not_exist(void)" (?does_not_exist@@YAHXZ) referenced in function "void __cdecl TextScan(struct FileTextStats &,char const *,char const *,bool,bool,__int64)" (?TextScan@@YAXAAUFileTextStats@@PBD1_N2_J@Z)

ByteComparator.cpp file, this is the source of the linker problem
* "int \_\_cdecl does\_not\_exist(void)" - This is the symbol it couldn't find, in this case a function named does\_not\_exist()
At this point, in many cases the fastest way to resolution is to search the code base for this function and find where the implementation is. Once you know where the function is implemented you just have to make sure the two places get linked together.
If you're using VS2005, you would use the "Project Dependencies..." right-click menu. If you're using gcc, you would look in your makefiles for the executable generation step (gcc | [

In a second scenario, you may be missing an "external" dependency, which you don't have code for. The Win32 libraries are often times implemented in static libraries that you have to link to. In this case, go to [MSDN](http://msdn.microsoft.com/en-us/default.aspx) or ["Microsoft Google"](http://www.google.com/microsoft) and search for the API. At the bottom of the API description the library name is given. Add this to your project properties "Configuration Properties->Linker->Input->Additional Dependencies" list. For example, the function timeGetTime()'s [page on MSDN](http://msdn.microsoft.com/en-us/library/ms713418(VS.85).aspx) tells you to use Winmm.lib at the bottom of the page. | [

I'm the second dev and a recent hire here at a PHP/MySQL shop. I was hired mostly due to my experience in wrangling some sort of process out of a chaotic mess. At least, that's what I did at my last company. ;)
Since I've been here (a few months now), I've brought on board my boss, my product manager and several other key figures (But mostly chickens, if you pardon the Scrum-based stereotyping). I've also helped bring in some visibility to the development cycle of a major product that has been lagging for over a year. People are loving it! | [

Without her input, I started the Scrum practices (daily scrums, burndown charts and other things I've found that worked for me and my previous teams (ala H. Kniberg's cool wall chart).

While Scrum other agile methodologies like it embody a lot of good practices, sometimes giving it a name and making it (as many bloggers have commented on) a "religion" that must be adopted in the workplace is rather offputting to a lot of people, including myself.

**Is there anything built into the core C# libraries that can give me an immutable Dictionary?**
Something along the lines of *Java's*:
```
Collections.unmodifiableMap(myMap);
```
And just to clarify, I am not looking to stop the keys / values themselves from being changed, just the structure of the Dictionary. I want something that fails fast and loud if any of IDictionary's mutator methods are called (`Add, Remove, Clear`).
No, but a wrapper is rather trivial:

Every time I create an object that has a collection property I go back and forth on the best way to do it?
1. public property with a getter that
returns a reference to private variable
2. explicit get\_ObjList and set\_ObjList
methods that return and create new or cloned
objects every time
3. explicit get\_ObjList that returns an
IEnumerator and a set\_ObjList that
takes IEnumerator
Does it make a difference if the collection is an array (i.e., objList.Clone()) versus a List?
If returning the actual collection as a reference is so bad because it creates dependencies, then why return any property as a reference? Anytime you expose an child object | [

as a reference the internals of that child can be changed without the parent "knowing" unless the child has a property changed event. Is there a risk for memory leaks?
And, don't options 2 and 3 break serialization? Is this a catch 22 or do you have to implement custom serialization anytime you have a collection property?
The generic ReadOnlyCollection seems like a nice compromise for general use. It wraps an IList and restricts access to it. Maybe this helps with memory leaks and serialization. However it still has [enumeration concerns](http://www.coversant.net/Coversant/Blogs/tabid/88/EntryID/34/Default.aspx)
Maybe it just depends. If you don't care that the collection | [

is modified, then just expose it as a public accessor over a private variable per #1. If you don't want other programs to modify the collection then #2 and/or #3 is better.
Implicit in the question is why should one method be used over another and what are the ramifications on security, memory, serialization, etc.?
How you expose a collection depends entirely on how users are intended to interact with it.

This strategy is used for the `Items` collections on the WindowsForms and WPF `ItemsControl` controls, where users add and remove items they want the control to display. These controls publish the actual collection and use callbacks or event listeners to keep track of items.
WPF also exposes some settable collections to allow users to display a collection of items they control, such as the `ItemsSource` property on `ItemsControl` (option #3 from the original question). However, this is not a common use case.

object, then you can use a readonly collection, as [Quibblesome](https://stackoverflow.com/questions/35007/how-to-expose-a-collection-property#35065) suggested:
```
private readonly List<T> myPrivateCollection_ = new ...;
private ReadOnlyCollection<T> myPrivateCollectionView_;
public ReadOnlyCollection<T> MyCollection {
get {
if( this.myPrivateCollectionView_ == null ) { /* lazily initialize view */ }
return this.myPrivateCollectionView_;
}
}
```
Note that `ReadOnlyCollection<T>` provides a live view of the underlying collection, so you only need to create the view once.
If the internal collection does not implement `IList<T>`, or if you want to restrict access to more advanced users, you can instead wrap access to the collection through an enumerator:
```
public IEnumerable<T> MyCollection {
get | [

{
foreach( T item in this.myPrivateCollection_ )
yield return item;
}
}
```
This approach is simple to implement and also provides access to all the members without exposing the internal collection. However, it does require that the collection remain unmodfied, as the BCL collection classes will throw an exception if you try to enumerate a collection after it has been modified. If the underlying collection is likely to change, you can either create a light wrapper that will enumerate the collection safely, or return a copy of the collection.

to expose arrays rather than higher-level collections, then you should return a copy of the array to prevent users from modifying it (option #2 from the orginal question):
```
private T[] myArray_;
public T[] GetMyArray( ) {
T[] copy = new T[this.myArray_.Length];
this.myArray_.CopyTo( copy, 0 );
return copy;
// Note: if you are using LINQ, calling the 'ToArray( )'
// extension method will create a copy for you.
}
```
You should not expose the underlying array through a property, as you will not be able to tell when users modify it. To allow modifying the array, you can | [

either add a corresponding `SetMyArray( T[] array )` method, or use a custom indexer:

public T this[int index] {
get { return this.myArray_[index]; }
set {
// TODO: validate new value; raise change event; etc.
this.myArray_[index] = value;
}

(of course, by implementing a custom indexer, you will be duplicating the work of the BCL classes :) | [

Is it possible to do image processing in silverlight 2.0?
What I want to do is take an image, crop it, and then send the new cropped image up to the server. I know I can fake it by clipping the image, but that only effects the rendering of the image. I want to create a new image.
After further research I have answered my own question. Answer: **No**. Since all apis would be in [System.Windows.Media.Imaging](http://msdn.microsoft.com/en-us/library/system.windows.media.imaging.aspx) and that namespace does not have the appropriate classes in Silverlight
I'm going to use fjcore. <http://code.google.com/p/fjcore/>

2... But there are no built in classes to help you. But you can load any image into a byte array, and start manipulating it, or implement your own image encoder.
Joe Stegman got lots of great information about "editable images" in Silverlight over at <http://blogs.msdn.com/jstegman/>. He does things like applying filters to images, generating mandlebrots and more.

I'm getting a `NoSuchMethodError` error when running my Java program. What's wrong and how do I fix it?
Without any more information it is difficult to pinpoint the problem, but the root cause is that you most likely have compiled a class against a different version of the class that is missing a method, than the one you are using when running it.
Look at the stack trace ... If the exception appears when calling a method on an object in a library, you are most likely using separate versions of the library when compiling and running. Make sure you have the | [

If the exception appears when calling a method on objects instantiated by classes *you* made, then your build process seems to be faulty. Make sure the class files that you are actually running are updated when you compile. | [

I'm working on a side project that would be a simple web application to maintain a list of classes and their upcoming schedules.
I would really like to use Linq to SQL for this project, but unfortunately the server environment I'm developing for only has MySql available. I've dabbled briefly with Subsonic but it just doesn't get the job done.
The database requirements for this application aren't that great, though, so I'm curious if using an MDF file in App\_Data would be a workable solution. Otherwise, it appears I'm going to have to hand-code sql queries which I want to avoid at | [
