Following this question: [Good crash reporting library in c#](https://stackoverflow.com/questions/49224/good-crash-reporting-library-in-c) Is there any library like CrashRpt.dll that does the same on Linux? That is, generate a failure report including a core dump and any necessary environment and notify the developer about it? Edit: This seems to be a duplicate of [this question](https://stackoverflow.com/questions/18265/getting-stack-traces-on-unix-systems-automatically) See *[Getting stack traces on Unix systems, automatically](https://stackoverflow.com/questions/18265/getting-stack-traces-on-unix-systems-automatically)* on Stack Overflow.

Embedded custom-tag in dynamic content (nested tag) not rendering. I have a page that pulls dynamic content from a javabean and passes the list of objects to a custom tag for processing into html. Within each object is a bunch of html to be output that contains a second custom tag that I would like to also be rendered. The problem is that the tag invocation is rendered as plaintext. An example might serve me better. 1 Pull information from a database and return it to the page via a javabean. Send this info to a custom tag for outputting. ``` <jsp:useBean id="ImportantNoticeBean" scope="page" class="com.mysite.beans.ImportantNoticeProcessBean"/>

inner tags rendered (example is for SimpleTag doTag method).

Is it correct to link a static library (.lib) compiled with VS 2005 with a program which is compiled with VS 2008? Both library and my program are written in C++. This program is run on Windows Mobile 6 Professional emulator. This seems to work, there are no linking errors. However the program crashes during startup because strange things happen inside the linked library. E.g. lib can return a vector of characters with size of big negative number. There are no such problems when the program is compiled with VS 2005. What is even more strange the problem is only when using release

configuration for the build. When compiling using debug configuration the problem doesn't occur. VS2005 and VS2008 use different STL implementations. When the VS2005 code returns a vector, the object has memory layout different from what VS2008 expects. That should be the reason for the broken values you see in the returned date. As a rule of thumb, you should always compile all C++ modules of a project with the same compiler and all settings/#defines equal. One particular #define that causes similar behaviour is the SECURE\_SCL #define of VS2008. Two modules compiled with different settings will create exactly your problems, because #defining SECURE\_SCL introduces

Is it possible to prevent an asp.net Hyperlink control from linking, i.e. so that it appears as a label, without actually having to replace the control with a label? Maybe using CSS or setting an attribute? I know that marking it as disabled works but then it gets displayed differently (greyed out). To clarify my point, I have a list of user names at the top of my page which are built dynamically using a user control. Most of the time these names are linkable to an email page. However if the user has been disabled the name is displayed in grey

but currently still links to the email page. I want these disabled users to not link. I know that really I should be replacing them with a label but this does not seem quite as elegant as just removing the linking ability usings CSS say (if thats possible). They are already displayed in a different colour so its obvious that they are disabled users. I just need to switch off the link. This sounds like a job for JQuery. Just give a specific class name to all of the HyperLink controls that you want the URLs removed and then apply the following

JQuery snippet to the bottom of your page: ``` $(document).ready(function() { $('a.NoLink').removeAttr('href') }); ``` All of the HyperLink controls with the class name "NoLink" will automatically have all of their URLs removed and the link will appear to be nothing more than text. A single line of JQuery can solve your problem.

[CSS Attribute selectors](http://www.w3.org/TR/REC-CSS2/selector.html#attribute-selectors) allow the selection of elements based on attribute values. Unfortunately, I've not used them in years (mainly because they're not supported by all modern browsers). However, I remember distinctly that I was able to use them to adorn all external links with an icon, by using a code similar to the following: ``` a[href=http] { background: url(external-uri); padding-left: 12px; } ``` The above code doesn't work. My question is: **How does it work?** How do I select all `<a>` tags whose `href` attribute starts with `"http"`? The official CSS spec (linked above) doesn't even mention that

this is possible. But I do remember doing this. (*Note*: The obvious solution would be to use `class` attributes for distinction. I want to avoid this because I have little influence of the way the HTML code is built. All I can edit is the CSS code.) As for CSS 2.1, see <http://www.w3.org/TR/CSS21/selector.html#attribute-selectors> Executive summary: ``` Attribute selectors may match in four ways: [att] Match when the element sets the "att" attribute, whatever the value of the attribute.

[att~=val] Match when the element's "att" attribute value is a space-separated list of "words", one of which is exactly "val". If this selector is used, the words in the value must not contain spaces (since they are separated by spaces).

How do I lock compiled Java classes to prevent decompilation? I know this must be very well discussed topic on the Internet, but I could not come to any conclusion after referring them. Many people do suggest obfuscator, but they just do renaming of classes, methods, and fields with tough-to-remember character sequences but what about sensitive constant values? For example, you have developed the encryption and decryption component based on a password based encryption technique. Now in this case, any average Java person can use [JAD](http://www.kpdus.com/jad.html) to decompile the class file and easily retrieve the password value (defined as constant) as well as

Or should such sensitive components be built in native code (for example, VC++) and call them via [JNI](http://en.wikipedia.org/wiki/Java_Native_Interface)? Some of the more advanced Java bytecode obfuscators do much more than just class name mangling.

Are the naming conventions similar in different languages? If not, what are the differences? As others have said, things vary a lot, but here's a rough overview of the most commonly used naming conventions in various languages: `lowercase, lowercase_with_underscores`: Commonly used for local variables and function names (typical C syntax). `UPPERCASE, UPPERCASE_WITH_UNDERSCORES:` Commonly used for constants and variables that never change. Some (older) languages like BASIC also have a convention for using all upper case for all variable names. `CamelCase, javaCamelCase:` Typically used for function names and variable names. Some use it only for functions and combine it with lowercase or lowercase\_with\_underscores for variables. When javaCamelCase is

used, it's typically used both for functions and variables. This syntax is also quite common for external APIs, since this is how the Win32 and Java APIs do it. (Even if a library uses a different convention internally they typically export with the (java)CamelCase syntax for function names.) `prefix_CamelCase, prefix_lowercase, prefix_lowercase_with_underscores:` Commonly used in languages that don't support namespaces (i.e. C). The prefix will usually denote the library or module to which the function or variable belongs. Usually reserved to global variables and global functions. Prefix can also be in UPPERCASE. Some conventions use lowercase prefix for internal functions and variables and UPPERCASE

I have a table containing prices for a lot of different "things" in a MS SQL 2005 table. There are hundreds of records per thing per day and the different things gets price updates at different times. ``` ID uniqueidentifier not null, ThingID int NOT NULL, PriceDateTime datetime NOT NULL, Price decimal(18,4) NOT NULL ``` I need to get today's latest prices for a group of things. The below query works but I'm getting hundreds of rows back and I have to loop trough them and only extract the latest one per ThingID. How can I (e.g. via a GROUP BY) say that I want the latest

This will add the possible risk of inconsistent data, but it will speed up the whole process a lot when the table gets bigger (if it is in an index). Then all you need

to do is to... ``` SELECT * FROM Thing WHERE ThingID IN (1,2,3,4) AND IsCurrent = 1 ``` **UPDATE** Okay, Markus updated the question to show that ID is a uniqueid, not an int.

I'm just about wrapped up on a project where I was using a commercial SVN provider to store the source code. The web host the customer ultimately picked includes a repository as part of the hosting package, so, now that the project is over, I'd like to relocate the repository to their web host and discontinue the commercial account. How would I go about doing this? If you want to move the repository and keep history, you'll probably need filesystem access on both hosts. The simplest solution, if your backend is FSFS (the default on recent versions), is to make a filesystem

copy of the entire repository folder. If you have a Berkley DB backend, if you're not sure of what your backend is, or if you're changing SVN version numbers, you're going to want to use svnadmin to dump your old repository and load it into your new repository. Using `svnadmin dump` will give you a single file backup that you can copy to the new system. Then you can create the new (empty) repository and use `svnadmin load`, which will essentially replay all the commits along with its metadata (author, timestamp, etc).

you do `svnadmin load`, make sure you use the `--force-uuid` option, or otherwise people are going to have problems switching to the new repository. Subversion uses a UUID to identify the repository internally, and it won't let you switch a working copy to a different repository. If you don't have filesystem access, there may be other third party options out there (or you can write something) to help you migrate: essentially you'd have to use the svn log to replay each revision on the new repository, and then fix up the metadata afterwards. You'll need the pre-revprop-change and post-revprop-change hook scripts

Is there a C# equivalent for the VB.NET `FormatNumber` function?

Using the .ToString() method your example could be written as: ``` JSArrayString += "^" + (inv.RRP * oCountry.ExchangeRate).ToString("#0.00") ``` Alternatively using the String.Format() it could written as: ``` JSArrayString = String.Format("{0}^{1:#0.00}",JSArrayString,(inv.RRP * oCountry.ExchangeRate)) ``` In both of the above cases I have used custom formatting for the currency with # representing an optional place holder and 0 representing a 0 or value if one exists.

How do you set your Cocoa application as the default web browser? I want to create an application that is launched by default when the user clicks on an HTTP or HTTPS link in other applications (Mail, iChat etc.). There are four steps to making an app that can act as the default web browser. The first three steps allow your app to act as a role handler for the relevant URL schemes (HTTP and HTTPS) and the final step makes it the default role handler for those schemes. **1) Add the URL schemes your app can handle to your application's info.plist file** To

add support for `http://` and `https://` you'd need to add the following to your application's info.plist file. This tells the OS that your application is capable of handling HTTP and HTTP URLs. ```xml <key>CFBundleURLTypes</key> <array> <dict> <key>CFBundleURLName</key> <string>http URL</string> <key>CFBundleURLSchemes</key> <array> <string>http</string> </array> </dict> <dict>

It doesn't matter which object you add this method to, that'll be explicitly passed to the Event Manager in the next step.

The URL handler method should look something like this: ``` - (void)getUrl:(NSAppleEventDescriptor *)event withReplyEvent:(NSAppleEventDescriptor *)replyEvent { // Get the URL NSString *urlStr = [[event paramDescriptorForKeyword:keyDirectObject] stringValue]; //TODO: Your custom URL handling code here } ``` **3) Register the URL handler method** Next, tell the event manager which object and method to call when it wants to use your app to load an URL. In the code here I'm passed `self` as the event handler, assuming that we're calling `setEventHandler` from the same object that defines the `getUrl:withReplyEvent:` method. You should add this code somewhere in your application's

I have played with the idea of using a wiki (MediaWiki) to centralize all project information for a development project. This was done using extensions that pull information from SVN (using [SVNKit](http://svnkit.com/)) and by linking to Bugzilla to extract work assigned to a developer or work remaining for a release. Examples: ``` <bugzilla type="summary" user="richard.tasker@gmail.com" /> ``` would return a summary ![Bugzilla Summary](https://i.stack.imgur.com/rfJjy.png) ``` <bugzilla type="status" status="ASSIGNED" product="SCM BEPPI" /> ``` would return ![Bugzilla Status](https://i.stack.imgur.com/YSV0t.png) Do you think that this would be useful? If so then what other integrations would you think would be valuable? I think this would be extremly useful. Depending on the size of a project team members come and

go. And a wiki is a good tool to keep the history and the "spirit" of a project available to new team members. I did that in many projects, and though the projects were already finished, all the informations are available. One more idea: also try to integrate meeting schedules, minutes etc. If your team communicates via IM, try to integrate a log of the conversations.

Our investigations have shown us that not all browsers respect the HTTP cache directives in a uniform manner. For security reasons we do not want certain pages in our application to be cached, **ever,** by the web browser. This must work for at least the following browsers: * Internet Explorer 6+ * Firefox 1.5+ * Safari 3+ * Opera 9+ * Chrome Our requirement came from a security test. After logging out from our website you could press the back button and view cached pages. Introduction ============ The correct minimum set of headers that works across all mentioned clients (and proxies): ``` Cache-Control: no-cache, no-store, must-revalidate Pragma: no-cache Expires: 0 ``` The [`Cache-Control`](http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9) is per the

HTTP 1.1 spec for clients and proxies (and implicitly required by some clients next to `Expires`). The [`Pragma`](http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.32) is per the HTTP 1.0 spec for prehistoric clients. The [`Expires`](http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.21) is per the HTTP 1.0 and 1.1 specs for clients and proxies. In HTTP 1.1, the `Cache-Control` takes precedence over `Expires`, so it's after all for HTTP 1.0 proxies only. If you don't care about IE6 and its broken caching when serving pages over HTTPS with only `no-store`, then you could omit `Cache-Control: no-cache`. ``` Cache-Control: no-store, must-revalidate Pragma: no-cache Expires: 0 ``` If you don't care about IE6 nor HTTP 1.0 clients (HTTP 1.1 was introduced in

1997), then you could omit `Pragma`. ``` Cache-Control: no-store, must-revalidate Expires: 0 ``` If you don't care about HTTP 1.0 proxies either, then you could omit `Expires`. ``` Cache-Control: no-store, must-revalidate ``` On the other hand, if the server auto-includes a valid `Date` header, then you could theoretically omit `Cache-Control` too and rely on `Expires` only. ``` Date: Wed, 24 Aug 2016 18:32:02 GMT Expires: 0 ``` But that may fail if e.g. the end-user manipulates the operating system date and the client software is relying on it.

5.2.2](http://www.w3.org/TR/html4/charset.html#h-5.2.2). Take care with this when you don't specify them programmatically because the webserver can namely include some default values. Generally, you'd better just **not** specify the HTML meta tags to avoid confusion by starters and rely on hard HTTP response headers. Moreover, specifically those `<meta http-equiv>` tags are [**invalid**](http://validator.w3.org) in HTML5.

Jquery has a great language construct that looks like this: ``` $(document).ready(function() { $("a").click(function() { alert("Hello world!"); }); }); ``` As you might guess this, once the document has loaded, binds a custom function to the onClick event of all ***a*** tags. The question is, how can I achieve this same kind of behavior in Prototype? Prototype 1.6 provides the ["dom:loaded"](http://prototypejs.org/api/document/observe) event on document: ``` document.observe("dom:loaded", function() { $$('a').each(function(elem) { elem.observe("click", function() { alert("Hello World"); }); }); }); ``` I also use the [each](http://prototypejs.org/api/enumerable/each) iterator on

I'm trying to find a source control for my own personal use that's as simple as possible. The main feature I need is being able to read/pull a past version of my code. I am the only developer. I've looked at a lot of different version control systems, but they all seem way more complicated than I need. I need one that's simple, runs under Windows, and doesn't expose itself to the network. Specifically, the version control system should *not* require exposing an HTTP interface, it should interact with the local filesystem only. It just needs to be a version control

Most of the work I do is with what could be considered enterprise Web applications. These projects have large budgets, longer timelines (from 3-12 months), and heavy customizations. Because as developers we have been touting the idea of the Web as the next desktop OS, customers are coming to expect the software running on this "new OS" to react the same as on the desktop. That includes easy to manage automatic upgrades. In other words, "An update is available. Do you want to upgrade?" Is this even a realistic expectation?

Large installations have peculiar issues that don't apply to small ones. For example, with 2000 users (not all of whom are, let us say, the most sophisticated of tool users), tool-training is a big deal: training time, internal demos, internal process documents, etc.. They cannot unleash a new feature or UI change without a chance to understand how it fits in their process and therefore what their internal best practices are and how to communicate that to their users.

when applications fail, it's the internal IT team who are responsible. Therefore, they want time to install a new version in a test area, beat it up, and deploy on a Saturday only when they're good and ready. I can see the value in making minor patches more easy to install, particularly when the patch is just for a bug-fix and not for anything that would require retraining, and if the admins still get final say over when it's installed. But even then, I don't believe anyone has ever asked for this! Whether because they don't want it or they are

In my application I have a window which I popup with small messages on it (think similar to tooltip). This window uses the layered attributes to draw alpha backgrounds etc. If I have several of these windows open at once, and I click one with my mouse, when they disappear they cause my application to lose focus (it switches focus to the app behind the current one). How do I stop any interaction in my window? Multithreaded programming is hard to grasp in the beginning (and veterans still fail sometimes) and BackgroundWorker makes it a bit easier to use.

that BackgroundWorker has functionality which is easy to implement but even easier to wrongly implement in a subtle way, like cancellation. I use it if I have and need a progress update, so I can display a meaningful progress bar. If not, I use a Thread (or borrow from the ThreadPool), because I don't need all the functionality of BackgroundWorker and am proficient enough with threads to start a Thread and wait for it to stop. As for delegates for non-related tasks, I use those of the Thread classes, like plain `void ThreadStart()`, or I create my own.

I know I've seen this in the past, but I can't seem to find it now. Basically I want to create a page that I can host on a [dasBlog](http://www.codeplex.com/dasblog) instance that contains the layout from my theme, but the content of the page I control. Ideally the content is a user control or ASPX that I write. Anybody know how I can accomplish this? The easist way to do this is to "hijack" the FormatPage functionality. First add the following to your web.config in the newtelligence.DasBlog.UrlMapper section: ``` <add matchExpression="(?&lt;basedir&gt;.*?)/Static\.aspx\?=(?&lt;value&gt;.+)" mapTo="{basedir}/FormatPage.aspx?path=content/static/{value}.format.html" /> ``` Now you can create a directory in your content directory called static. From there,

you can create html files and the file name will map to the url like this: <http://BASEURL/Static.aspx?=FILENAME> will map to a file called: /content/static/FILENAME.format.html You can place anything in that file that you would normally place in itemTemplate.blogtemplate, except it obviously won't have any post data. But you can essentially use this to put other macros, and still have it use the hometemplate.blogtemplate to keep the rest of your theme wrapped around the page.

What is the difference between `UNION` and `UNION ALL`? `UNION` removes duplicate records (where all columns in the results are the same), `UNION ALL` does not. There is a performance hit when using `UNION` instead of `UNION ALL`, since the database server must do additional work to remove the duplicate rows, but usually you do not want the duplicates (especially when developing reports). To identify duplicates, records must be comparable types as well as compatible types. This will depend on the SQL system. For example the system may truncate all long text fields to make short text fields for comparison (MS Jet), or

I know that the .NET framework looks for referenced DLLs in several locations * Global assembly cache (GAC) * Any private paths added to the AppDomain * The current directory of the executing assembly What order are those locations searched? Is the search for a DLL ceased if a match is found or does it continue through all locations (and if so, how are conflicts resolved)? *Also, please confirm or deny those locations and provide any other locations I have failed to mention.* Assembly loading is a rather elaborate process which depends on lots of different factors like configuration files, publisher policies, appdomain settings, CLR hosts,

Occasionally a program on a Windows machine goes crazy and just hangs. So I'll call up the task manager and hit the "End Process" button for it. However, this doesn't always work; if I try it enough times then it'll usually die eventually, but I'd really like to be able to just kill it immediately. On Linux I could just `kill -9` to guarantee that a process will die. This also could be used for writing batch scripts and writing batch scripts is programming. **Is there some** program or **command that comes with Windows that will always kill a process?** A free

third-party app would be fine, although I'd prefer to be able to do this on machines I sit down at for the first time. "End Process" on the Processes-Tab calls `TerminateProcess` which is the most ultimate way Windows knows to kill a process. If it doesn't go away, it's currently locked waiting on some kernel resource (probably a buggy driver) and there is nothing (short of a reboot) you could do to make the process go away. Have a look at this blog-entry from wayback when: <http://blogs.technet.com/markrussinovich/archive/2005/08/17/unkillable-processes.aspx> Unix based systems like Linux also have that problem where processes could survive a `kill -9` if

they are in what's known as "Uninterruptible sleep" (shown by top and ps as state `D`) at which point the processes sleep so well that they can't process incoming signals (which is what `kill` does - sending signals). Normally, Uninterruptible sleep should not last long, but as under Windows, broken drivers or broken userpace programs (`vfork` without `exec`) can end up sleeping in `D` forever.

The .Net generated code for a form with the "DefaultButton" attribute set contains poor javascript that allows the functionality to work in IE but not in other browsers (Firefox specifcially). Hitting enter key does submit the form with all browsers but Firefox cannot disregard the key press when it happens inside of a <textarea> control. The result is a multiline text area control that cannot be multiline in Firefox as the enter key submits the form instead of creating a new line.

I understand the value of the three-part service/host/client model offered by WCF. But is it just me or does it seem like WCF took something pretty direct and straightforward (the ASMX model) and made a mess out of it? Is there an alternative to using SvcUtil's command line step back in time to generate the proxy? With ASMX services a test harness was automatically provided; is there a good alternative today with WCF? I appreciate that the WS\* stuff is more tightly integrated with WCF and hope to find some payoff for WCF there, but geeze, otherwise I'm perplexed. Also,

the state of books available for WCF is abysmal at best. Juval Lowy, a superb author, has written a good O'Reilly reference book "Programming WCF Services" but it doesn't do that much (for me anyway) for learning now to use WCF. That book's precursor (and a little better organized, but not much, as a tutorial) is Michele Leroux Bustamante's Learning WCF. It has good spots but is outdated in place and its corresponding Web site is gone. Do you have good WCF learning references besides just continuing to Google the bejebus out of things?

On that website she provides updated code compatible with VS2008 for all the examples in her book. If you order from Amazon, you will get the reprint which is updated. WCF is not *only* a replacement for ASMX. Sure it can (and does quite well) replace ASMX, but the real benefit is that it allows your services to be self-hosted.

framework is *highly* configurable, and the ability to serve multiple endpoints over multiple protocols is amazing, IMO. While you can still generate proxy classes from the "Add Service Reference" option, it's not necessary. All you really have to do is copy your ServiceContract interface and tell your code where to find the endpoint for the service, and that's it. You can call methods from the service with very little code. Using this method, you have complete control over the implementation. Regardless of the method you choose to generate a proxy class, Michele shows both and uses both in her **excellent** series

of webcasts on the subject. Michele has tons of great material out there, and I recommend you check out her website(s). Here's some links that were incredibly helpful for me as I was learning WCF. I hope that you'll come to realize how strong WCF really is, and how easy it is to implement. The learning curve is a little bit steep, but the rewards for your time investment are well worth it: * Michele's webcasts: <http://www.dasblonde.net/2007/06/24/WCFWebcastSeries.aspx> * Michele's book website (alive and updated for VS2008): <http://www.thatindigogirl.com/> I recommend you watch at least 1 of Michele's webcasts. She is a very effective presenter, and

she's obviously incredibly knowledgeable when it comes to WCF. She does a great job of demystifying the inner workings of WCF from the ground up.

What options exist for accessing different databases from C++? Put differently, what alternatives are there to ADO? What are the pros and cons? 1. [Microsoft ODBC](http://msdn.microsoft.com/en-us/library/ms710252.aspx). 2. The MFC ODBC classes such as [CDatabase](http://msdn.microsoft.com/en-us/library/2dhc1abk.aspx). 3. [OleDB](http://msdn.microsoft.com/en-us/library/ms722784.aspx) (via COM). 4. And you can always go through the per-RDBMS native libraries (for example, the [SQL Server native library](http://msdn.microsoft.com/en-us/library/ms722784.aspx)) 5. [DAO](http://msdn.microsoft.com/en-us/library/aa163992.aspx) (don't). 6. 3rd party ORM providers. I would recommend going through ODBC or OleDB by default. Native libraries really restrict you, DAO is no fun, there aren't a lot of great 3rd-party ORM for C++/Windows.

I have a 200+ case statement in Classic ASP which is getting out of control. It sets 5 variables, based on which case is selected. Address, Phone, Name etc. Just sets the variables and nothing else in each case. Databases or files are not an option for this application. Coming from the Perl world I would use a hash to store this info. Brian, the classic ASP equivalent of a Perl hash is the [Scripting.Dictionary](http://www.microsoft.com/technet/scriptcenter/guide/sas_scr_ildk.mspx?mfr=true) object.

My company is going to be storing sensitive data for our customers, and will be encrypting data using one of the managed .NET encryption algorithm classes. Most of the work is done, but we haven't figured out how/where to store the key. I've done some light searching and reading, and it seems like a hardware solution might be the most secure. Does anyone have any recommendations on a key storage solution or method? --- Thanks for your replies, everyone. spoulson, the issue is actually both the "scopes" that you mentioned. I suppose I should have been clearer. The data itself, as well as the
