• Using the @ in SQL Azure Connections

  - by BuckWoody

  The other day I was working with a client on an application they were changing to a hybrid architecture – some data on-premise and other data in SQL Azure and Windows Azure Blob storage. I had them make a couple of corrections - the first was that all communications to SQL Azure need to be encrypted. It’s a simple addition to the connection string, depending on the library you use. Which brought up another interesting point. They had been using something that looked like this, using the .NET provider: Server=tcp:[serverName].database.windows.net;Database=myDataBase; User ID=LoginName;Password=myPassword; Trusted_Connection=False;Encrypt=True; This includes most of the formatting needed for SQL Azure. It specifies TCP as the transport mechanism, the database name is included, Trusted_Connection is off, and encryption is on. But it needed one more change: Server=tcp:[serverName].database.windows.net;Database=myDataBase; User ID=[LoginName]@[serverName];Password=myPassword; Trusted_Connection=False;Encrypt=True; Notice the difference? It’s the User ID parameter. It includes the @ symbol and the name of the server – not the whole DNS name, just the server name itself. The developers were a bit surprised, since it had been working with the first format that just used the user name. Why did both work, and why is one better than the other? It has to do with the connection library you use. For most libraries, the user name is enough. But for some libraries (subject to change so I don’t list them here) the server name parameter isn’t sent in the way the load balancer understands, so you need to include the server name right in the login, so the system can parse it correctly. Keep in mind, the string limit for that is 128 characters – so take the @ symbol and the server name into consideration for user names. The user connection info is detailed here: http://msdn.microsoft.com/en-us/library/ee336268.aspx Upshot? Include the @servername on your connection string just to be safe. And plan for that extra space…

• Notes on implementing Visual Studio 2010 Navigate To

  - by cyberycon

  One of the many neat functions added to Visual Studio in VS 2010 was the Navigate To feature. You can find it by clicking Edit, Navigate To, or by using the keyboard shortcut Ctrl, (yes, that's control plus the comma key). This pops up the Navigate To dialog that looks like this: As you type, Navigate To starts searching through a number of different search providers for your term. The entries in the list change as you type, with most providers doing some kind of fuzzy or at least substring matching. If you have C#, C++ or Visual Basic projects in your solution, all symbols defined in those projects are searched. There's also a file search provider, which displays all matching filenames from projects in the current solution as well. And, if you have a Visual Studio package of your own, you can implement a provider too. Micro Focus (where I work) provide the Visual COBOL language inside Visual Studio (http://visualstudiogallery.msdn.microsoft.com/ef9bc810-c133-4581-9429-b01420a9ea40 ), and we wanted to provide this functionality too. This post provides some notes on the things I discovered mainly through trial and error, but also with some kind help from devs inside Microsoft. The expectation of Navigate To is that it searches across the whole solution, not just the current project. So in our case, we wanted to search for all COBOL symbols inside all of our Visual COBOL projects inside the solution. So first of all, here's the Microsoft documentation on Navigate To: http://msdn.microsoft.com/en-us/library/ee844862.aspx . It's the reference information on the Microsoft.VisualStudio.Language.NavigateTo.Interfaces Namespace, and it lists all the interfaces you will need to implement to create your own Navigate To provider. Navigate To uses Visual Studio's latest mechanism for integrating external functionality and services, Managed Extensibility Framework (MEF). MEF components don't require any registration with COM or any other registry entries to be found by Visual Studio. Visual Studio looks in several well-known locations for manifest files (extension.vsixmanifest). It then uses reflection to scan for MEF attributes on classes in the assembly to determine which functionality the assembly provides. MEF itself is actually part of the .NET framework, and you can learn more about it here: http://mef.codeplex.com/. To get started with Visual Studio and MEF you could do worse than look at some of the editor examples on the VSX page http://archive.msdn.microsoft.com/vsx . I've also written a small application to help with switching between development and production MEF assemblies, which you can find on Codeproject: http://www.codeproject.com/KB/miscctrl/MEF_Switch.aspx. The Navigate To interfaces Back to Navigate To, and summarizing the MSDN reference documentation, you need to implement the following interfaces: INavigateToItemProviderFactoryThis is Visual Studio's entry point to your Navigate To implementation, and you must decorate your implementation with the following MEF export attribute: [Export(typeof(INavigateToItemProviderFactory))]  INavigateToItemProvider Your INavigateToItemProviderFactory needs to return your implementation of INavigateToItemProvider. This class implements StartSearch() and StopSearch(). StartSearch() is the guts of your provider, and we'll come back to it in a minute. This object also needs to implement IDisposeable(). INavigateToItemDisplayFactory Your INavigateToItemProvider hands back NavigateToItems to the NavigateTo framework. But to give you good control over what appears in the NavigateTo dialog box, these items will be handed back to your INavigateToItemDisplayFactory, which must create objects implementing INavigateToItemDisplay  INavigateToItemDisplay Each of these objects represents one result in the Navigate To dialog box. As well as providing the description and name of the item, this object also has a NavigateTo() method that should be capable of displaying the item in an editor when invoked. Carrying out the search The lifecycle of your INavigateToItemProvider is the same as that of the Navigate To dialog. This dialog is modal, which makes your implementation a little easier because you know that the user can't be changing things in editors and the IDE while this dialog is up. But the Navigate To dialog DOES NOT run on the main UI thread of the IDE – so you need to be aware of that if you want to interact with editors or other parts of the IDE UI. When the user invokes the Navigate To dialog, your INavigateToItemProvider gets sent a TryCreateNavigateToItemProvider() message. Instantiate your INavigateToItemProvider and hand this back. The sequence diagram below shows what happens next. Your INavigateToItemProvider will get called with StartSearch(), and passed an INavigateToCallback. StartSearch() is an asynchronous request – you must return from this method as soon as possible, and conduct your search on a separate thread. For each match to the search term, instantiate a NavigateToItem object and send it to INavigateToCallback.AddItem(). But as the user types in the Search Terms field, NavigateTo will invoke your StartSearch() method repeatedly with the changing search term. When you receive the next StartSearch() message, you have to abandon your current search, and start a new one. You can't rely on receiving a StopSearch() message every time. Finally, when the Navigate To dialog box is closed by the user, you will get a Dispose() message – that's your cue to abandon any uncompleted searches, and dispose any resources you might be using as part of your search. While you conduct your search invoke INavigateToCallback.ReportProgress() occasionally to provide feedback about how close you are to completing the search. There does not appear to be any particular requirement to how often you invoke ReportProgress(), and you report your progress as the ratio of two integers. In my implementation I report progress in terms of the number of symbols I've searched over the total number of symbols in my dictionary, and send a progress report every 16 symbols. Displaying the Results The Navigate to framework invokes INavigateToItemDisplayProvider.CreateItemDisplay() once for each result you passed to the INavigateToCallback. CreateItemDisplay() is passed the NavigateToItem you handed to the callback, and must return an INavigateToItemDisplay object. NavigateToItem is a sealed class which has a few properties, including the name of the symbol. It also has a Tag property, of type object. This enables you to stash away all the information you will need to create your INavigateToItemDisplay, which must implement an INavigateTo() method to display a symbol in an editor IDE when the user double-clicks an entry in the Navigate To dialog box. Since the tag is of type object, it is up to you, the implementor, to decide what kind of object you store in here, and how it enables the retrieval of other information which is not included in the NavigateToItem properties. Some of the INavigateToItemDisplay properties are self-explanatory, but a couple of them are less obvious: Additional informationThe string you return here is displayed inside brackets on the same line as the Name property. In English locales, Visual Studio includes the preposition "of". If you look at the first line in the Navigate To screenshot at the top of this article, Book_WebRole.Default is the additional information for textBookAuthor, and is the namespace qualified type name the symbol appears in. For procedural COBOL code we display the Program Id as the additional information DescriptionItemsYou can use this property to return any textual description you want about the item currently selected. You return a collection of DescriptionItem objects, each of which has a category and description collection of DescriptionRun objects. A DescriptionRun enables you to specify some text, and optional formatting, so you have some control over the appearance of the displayed text. The DescriptionItems property is displayed at the bottom of the Navigate To dialog box, with the Categories on the left and the Descriptions on the right. The Visual COBOL implementation uses it to display more information about the location of an item, making it easier for the user to know disambiguate duplicate names (something there can be a lot of in large COBOL applications). Summary I hope this article is useful for anyone implementing Navigate To. It is a fantastic navigation feature that Microsoft have added to Visual Studio, but at the moment there still don't seem to be any examples on how to implement it, and the reference information on MSDN is a little brief for anyone attempting an implementation.

• xubuntu 12.04 can't change desktop background/wallpaper permanently

  - by Frank

  If I change the desktop background (wallpaper) via right-click on desktop = desktop settings = single image, and select another background image from the list, or add a photo of my own (via the "+" symbol), I can actually change the background image, but after logging out or restarting, the wallpaper is always reset to the original xubuntu 12.04 background. So, basically, I can't find a way to permanently change the desktop background. Any ideas?

• window.scrollBy only works in Firefox !? [closed]

  - by Patrick

  In my website I have this javascript code, adding a vertical offset when in the url a specific section of the page is specified (#): if (!!window.location.hash) window.scrollBy(0,-60); However this only works in Firefox... I'm pretty sure window.location.hash works in all browsers, that is, the symbol "sharp" is correctly detected in the url. However, the -60 offset only works in Firefox... this is the url, could you give me some insight ? http://patrickdiviacco.co.cc/#432 thanks

• How can I enable special Fn-Keys on my on lenovo s206 (e.g. touchpad on/off)?

  - by user2546783

  I can turn the touchpad off in the mouse settings, but two things won't work: The "disable while typing" option The standard on/off button for the touch pad won't work (it's the one with the little touchpad symbol crossed off, on the F6 key). I've tried any of the following combinations: Alt+F6 Fn+F6 Ctrl+F6 Super+F6 Shift+F6. Almost all the other keys of that kind work, like brightness control, volume control, Wifi toggle, but this one and the mic off and camera off won't work.

• Legitimate SEO Services

  SEO is symbol of search engine optimization which is the key to success in the business. No website has meaning if it is not properly promoted. Whenever any internet surfer is in search of any specific product, services or information he uses the simplest way of searching through search engine and this is habit of many people to only look in to five or six top websites for their purpose. No one has time to look in to 100 pages of search engine as there is no need when he finds in top pages.

• Replacing latex with unicode symbols

  - by Elazar Leibovich

  Often, during a conversation or an email, or at a forum, I would like to type some math, but I don't need full equation support. Unicode symbols should suffice. What I need is an easy way to type math related unicode symbols. Since I already know latex, it makes sense to use the latex symbol mnemonics to type the math symbols. What I currently did is to write an AutoHotKey script which automatically replaces \latexSymbol with the corresponding unicode symbol, using the "hotstrings" AutoHotKey feautres. However, the AutoHotKey hotstrings proved unstable for many strings. Having a couple of tens lines would cause AHK to fail recognizing the strings from time to time. Any other solution? (No, Alt+unicode number isn't convenient enough) Attached is my AHK script. The PutUni function is taken from here. ::\infty:: PutUni("e2889e") return ::\sum:: PutUni("e28891") return ::\int:: PutUni("e288ab") return ::\pm:: PutUni("c2b1") return ::\alpha:: PutUni("c991") return ::\beta:: PutUni("c992") return ::\phi:: PutUni("c9b8") return ::\delta:: PutUni("ceb4") return ::\pi:: PutUni("cf80") return ::\omega:: PutUni("cf89") return ::\in:: PutUni("e28888") return ::\notin:: PutUni("e28889") return ::\iff:: PutUni("e28794") return ::\leq:: PutUni("e289a4") return ::\geq:: PutUni("e289a5") return ::\sqrt:: PutUni("e2889a") return ::\neq:: PutUni("e289a0") return ::\subset:: PutUni("e28a82") return ::\nsubset:: PutUni("e28a84") return ::\nsubseteq:: PutUni("e28a88") return ::\subseteq:: PutUni("e28a86") return ::\prod:: PutUni("e2888f") return ::\N:: PutUni("e28495") return

• Uninstall Perl 5.10 and Install 5.8 on Ubuntu 10.04

  - by user48848

  I was using Ubuntu 8.04 with installed Perl 5.8.8. I had installed Bugzilla 3.4.4 with some custom scripts and it was working fine. I had to upgrade Ubuntu from 8.04 to 10.04 and automatically Perl is also upgraded from Perl 5.8 to 5.10. Now, accessing Bugzilla displays an error message related to Perl module. While trying to run checksetup.pl, I am getting the following error message: root@cvsnew:/var/www/bugzilla-3.4# perl checksetup.pl * This is Bugzilla 3.4.3 on perl 5.10.1 * Running on Linux 2.6.32-24-generic-pae #39-Ubuntu SMP Wed Jul 28 07:39:26 UTC 2010 Checking perl modules...

I explored this issue and found that this issue has come up because upgrading Ubuntu upgrades Perl 5.8 to 5.10 automatically. It seems like Perl 5.10.1 isn't binary compatible with the previous. Now, I want to uninstall Perl 5.10.1 and Install Perl 5.8.8 on my Ubuntu 10.04 box. I will appreciate if someone has already done that or share the required steps/commands to do it.

• Problems compiling coreutils-8.5 on Solaris 5.10 on Intel platform

  - by PP

  I am having trouble compiling coreutils-8.5 on Solaris 5.10 on the Intel platform using cc. Firstly I had the following error during ./configure: checking whether <wchar.h> uses 'inline' correctly... no configure: error: <wchar.h> cannot be used with this compiler (/tool/sunstudio12.1/bin/cc -xc99=all -g -D_REENTRANT). This seemed similar to the problem in this question. The solution was to edit configure and replace the reference of -xc99=all to -xc99=all,no_lib. This permitted the configure to complete. Then I ran /usr/sfw/bin/gmake and it progressed until I received the following message: Making all in src gmake[2]: Entering directory `/home/peterp/src/coreutils-8.5/src' gmake all-am gmake[3]: Entering directory `/home/peterp/src/coreutils-8.5/src' CCLD chroot Undefined first referenced symbol in file eaccess ../lib/libcoreutils.a(euidaccess.o) ld: fatal: Symbol referencing errors. No output written to chroot What could cause this problem? PS I was only compiling coreutils because I wanted colour ls.

  I'm trying to get git running in cygwin on a windows 7 machine I have git unpacked and the directory git-1.7.1.1 when i run make install from within that directory, I get CC fast-import.o In file included from builtin.h:4, from fast-import.c:147: git-compat-util.h:136:19: iconv.h: No such file or directory git-compat-util.h:140:25: openssl/ssl.h: No such file or directory git-compat-util.h:141:25: openssl/err.h: No such file or directory In file included from builtin.h:6, from fast-import.c:147: cache.h:9:21: openssl/sha.h: No such file or directory In file included from fast-import.c:156: csum-file.h:10: error: parse error before "SHA_CTX" csum-file.h:10: warning: no semicolon at end of struct or union csum-file.h:15: error: 'crc32' redeclared as different kind of symbol /usr/include/zlib.h:1285: error: previous declaration of 'crc32' was here csum-file.h:15: error: 'crc32' redeclared as different kind of symbol /usr/include/zlib.h:1285: error: previous declaration of 'crc32' was here csum-file.h:17: error: parse error before '}' token fast-import.c: In function `store_object': fast-import.c:995: error: `SHA_CTX' undeclared (first use in this function) fast-import.c:995: error: (Each undeclared identifier is reported only once fast-import.c:995: error: for each function it appears in.) fast-import.c:995: error: parse error before "c" fast-import.c:1000: warning: implicit declaration of function `SHA1_Init' fast-import.c:1000: error: `c' undeclared (first use in this function) fast-import.c:1001: warning: implicit declaration of function `SHA1_Update' fast-import.c:1003: warning: implicit declaration of function `SHA1_Final' fast-import.c: At top level: fast-import.c:1118: error: parse error before "SHA_CTX" fast-import.c: In function `truncate_pack': fast-import.c:1120: error: `to' undeclared (first use in this function) fast-import.c:1126: error: dereferencing pointer to incomplete type fast-import.c:1127: error: dereferencing pointer to incomplete type fast-import.c:1128: error: dereferencing pointer to incomplete type fast-import.c:1128: error: `ctx' undeclared (first use in this function) fast-import.c: In function `stream_blob': fast-import.c:1140: error: `SHA_CTX' undeclared (first use in this function) fast-import.c:1140: error: parse error before "c" fast-import.c:1154: error: `pack_file_ctx' undeclared (first use in this functio n) fast-import.c:1154: error: dereferencing pointer to incomplete type fast-import.c:1160: error: `c' undeclared (first use in this function) make: *** [fast-import.o] Error 1 I'm guessing that most of these errors are due to the iconv.h and openssl files which apparently are missing, but I can't figure out how I'm supposed to install those (if I am), or if there is some other way to get around this.

• Folder name in sidebar is changed, how to get it back?

  - by otakustay

  My OSX is Simplified Chinese, so the user folders in finder's sidebar is like this: AirDrop ???? ?? ?? ?? ?? ?? ?? These stand for AirDrop, Applications, Desktop, Documents, Downloads, Movies, Musics and Pictures. However, now with an accident, my "Downloads" folders in sidebar is changed to its original english name, and I don't why, so my sidebar is now look like: AirDrop ???? ?? ?? Downloads ?? ?? ?? I know do symbol link to these folders would cause such case but I cannot find any symbol links to my ~/Downloads folder. So is there any way to get the Chinese name back? it looks so weired and dirty. I have a time machine backup 3 days ago, but I have quite a lot modifications to my user folder these 3 days, so time machine may not be a good choice.

• Google Chrome 'ruined' after someone else logged in

  - by MHJ96

  Google Chrome was the default browser that came with my laptop. I have a Google account which I was logged into Chrome with. Someone else logged into my chrome using their account which has resulted in everything being lost. I logged in again to find my theme, bookmarks, history, most visited sites were gone and now instead of 'piling up' under the symbol already pinned to the Windows 7 task bar it opens a second symbol on the taskbar and 'piles up' under that instead which has never happened before. I have tried unpinning and repinning which didn't work. I have tried syncing my account numerous times to no avail, I have searched high and low on the Chrome forums for any kind of answer. I have tried accessing that thing in documents to try and recover my bookmarks but I can't find them (I had hidden files enabled etc etc). I really really want it back how it was as I had a lot of bookmarked sites and quick access to sites and everything was how i used it, and I hate that it now opens a new icon on the taskbar.

• PHP text formating: Detecting several symbols in a row

  - by ilnur777

  I have a kind of strange thing that I really nead for my text formating. Don't ask me please why I did this strange thing! ;-) So, my PHP script replaces all line foldings "\n" with one of the speacial symbol like "|". When I insert text data to database, the PHP script replaces all line foldings with the symbol "|" and when the script reads text data from the database, it replaces all special symbols "|" with line folding "\n". I want to restrict text format in the way that it will cut line foldings if there are more than 2 line foldings used in each separating texts. Here is the example of the text I want the script to format: this is text... this is text... this is text...this is text...this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... I want to restict format like: this is text... this is text... this is text...this is text...this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... So, at the first example there is only one line folding between 2 texts and on the second example there are 3 line foldings between 2 texts. How it can be possible to replace more than 2 line foldings symbols "|" if they are detected on the text? This is a kind of example I want the script to do: $text = str_replace("|||", "||", $text); $text = str_replace("||||", "||", $text); $text = str_replace("|||||", "||", $text); $text = str_replace("||||||", "||", $text); $text = str_replace("|||||||", "||", $text); ... $text = str_replace("||||||||||", "||", $text); $text = str_replace("|", "<br>", $text); HM, I HAVE PROBLEMS! THIS DOES NOT WORK WHEN TEXT DATA IS SENT IN POST METHOD. LOOK AT THIS: //REPLACING ALL LINE FOLDINGS WITH SPECIAL SYMBOL $_POST["text"] = str_replace("\n","|",$_POST["text"]); // REMOVING ALL LINE FOLDINGS $_POST["text"] = trim($_POST["text"]); // IF THERE ARE MORE THAN 3 LINE HOLDINGS - FORMAT TO 1 LINE HOLDING $_POST["text"] = preg_replace("/\|{3,}/", "||", $_POST["text"]); echo $_POST["text"];

• boost::function & boost::lambda again

  - by John Dibling

  Follow-up to post: http://stackoverflow.com/questions/2978096/using-width-precision-specifiers-with-boostformat I'm trying to use boost::function to create a function that uses lambdas to format a string with boost::format. Ultimately what I'm trying to achieve is using width & precision specifiers for strings with format. boost::format does not support the use of the * width & precision specifiers, as indicated in the docs: Width or precision set to asterisk (*) are used by printf to read this field from an argument. e.g. printf("%1$d:%2$.*3$d:%4$.*3$d\n", hour, min, precision, sec); This class does not support this mechanism for now. so such precision or width fields are quietly ignored by the parsing. so I'm trying to find other ways to accomplish the same goal. Here is what I have so far, which isn't working: #include <string> #include <boost\function.hpp> #include <boost\lambda\lambda.hpp> #include <iostream> #include <boost\format.hpp> #include <iomanip> #include <boost\bind.hpp> int main() { using namespace boost::lambda; using namespace std; boost::function<std::string(int, std::string)> f = (boost::format("%s") % boost::io::group(setw(_1*2), setprecision(_2*2), _3)).str(); std::string s = (boost::format("%s") % f(15, "Hello")).str(); return 0; } This generates many compiler errors: 1>------ Build started: Project: hacks, Configuration: Debug x64 ------ 1>Compiling... 1>main.cpp 1>.\main.cpp(15) : error C2872: '_1' : ambiguous symbol 1> could be 'D:\Program Files (x86)\boost\boost_1_42\boost/lambda/core.hpp(69) : boost::lambda::placeholder1_type &boost::lambda::`anonymous-namespace'::_1' 1> or 'D:\Program Files (x86)\boost\boost_1_42\boost/bind/placeholders.hpp(43) : boost::arg<I> `anonymous-namespace'::_1' 1> with 1> [ 1> I=1 1> ] 1>.\main.cpp(15) : error C2664: 'std::setw' : cannot convert parameter 1 from 'boost::lambda::placeholder1_type' to 'std::streamsize' 1> No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called 1>.\main.cpp(15) : error C2872: '_2' : ambiguous symbol 1> could be 'D:\Program Files (x86)\boost\boost_1_42\boost/lambda/core.hpp(70) : boost::lambda::placeholder2_type &boost::lambda::`anonymous-namespace'::_2' 1> or 'D:\Program Files (x86)\boost\boost_1_42\boost/bind/placeholders.hpp(44) : boost::arg<I> `anonymous-namespace'::_2' 1> with 1> [ 1> I=2 1> ] 1>.\main.cpp(15) : error C2664: 'std::setprecision' : cannot convert parameter 1 from 'boost::lambda::placeholder2_type' to 'std::streamsize' 1> No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called 1>.\main.cpp(15) : error C2872: '_3' : ambiguous symbol 1> could be 'D:\Program Files (x86)\boost\boost_1_42\boost/lambda/core.hpp(71) : boost::lambda::placeholder3_type &boost::lambda::`anonymous-namespace'::_3' 1> or 'D:\Program Files (x86)\boost\boost_1_42\boost/bind/placeholders.hpp(45) : boost::arg<I> `anonymous-namespace'::_3' 1> with 1> [ 1> I=3 1> ] 1>.\main.cpp(15) : error C2660: 'boost::io::group' : function does not take 3 arguments 1>.\main.cpp(15) : error C2228: left of '.str' must have class/struct/union 1>Build log was saved at "file://c:\Users\john\Documents\Visual Studio 2005\Projects\hacks\x64\Debug\BuildLog.htm" 1>hacks - 7 error(s), 0 warning(s) ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== My fundamental understanding of boost's lambdas and functions is probably lacking.

• What is the best way to solve an Objective-C namespace collision?

  - by Mecki

  Objective-C has no namespaces; it's much like C, everything is within one global namespace. Common practice is to prefix classes with initials, e.g. if you are working at IBM, you could prefix them with "IBM"; if you work for Microsoft, you could use "MS"; and so on. Sometimes the initials refer to the project, e.g. Adium prefixes classes with "AI" (as there is no company behind it of that you could take the initials). Apple prefixes classes with NS and says this prefix is reserved for Apple only. So far so well. But appending 2 to 4 letters to a class name in front is a very, very limited namespace. E.g. MS or AI could have an entirely different meanings (AI could be Artificial Intelligence for example) and some other developer might decide to use them and create an equally named class. Bang, namespace collision. Okay, if this is a collision between one of your own classes and one of an external framework you are using, you can easily change the naming of your class, no big deal. But what if you use two external frameworks, both frameworks that you don't have the source to and that you can't change? Your application links with both of them and you get name conflicts. How would you go about solving these? What is the best way to work around them in such a way that you can still use both classes? In C you can work around these by not linking directly to the library, instead you load the library at runtime, using dlopen(), then find the symbol you are looking for using dlsym() and assign it to a global symbol (that you can name any way you like) and then access it through this global symbol. E.g. if you have a conflict because some C library has a function named open(), you could define a variable named myOpen and have it point to the open() function of the library, thus when you want to use the system open(), you just use open() and when you want to use the other one, you access it via the myOpen identifier. Is something similar possible in Objective-C and if not, is there any other clever, tricky solution you can use resolve namespace conflicts? Any ideas? Update: Just to clarify this: answers that suggest how to avoid namespace collisions in advance or how to create a better namespace are certainly welcome; however, I will not accept them as the answer since they don't solve my problem. I have two libraries and their class names collide. I can't change them; I don't have the source of either one. The collision is already there and tips on how it could have been avoided in advance won't help anymore. I can forward them to the developers of these frameworks and hope they choose a better namespace in the future, but for the time being I'm searching a solution to work with the frameworks right now within a single application. Any solutions to make this possible?

• How can I disable 'output escaping' in minidom

  - by William

  I'm trying to build an xml document from scratch using xml.dom.minidom. Everything was going well until I tried to make a text node with a ® (Registered Trademark) symbol in. My objective is for when I finally hit print mydoc.toxml() this particular node will actually contain a ® symbol. First I tried: import xml.dom.minidom as mdom data = '®' which gives the rather obvious error of: File "C:\src\python\HTMLGen\test2.py", line 3 SyntaxError: Non-ASCII character '\xae' in file C:\src\python\HTMLGen\test2.py on line 3, but no encoding declared; see http://www.python.or g/peps/pep-0263.html for details I have of course also tried changing the encoding of my python script to 'utf-8' using the opening line comment method, but this didn't help. So I thought import xml.dom.minidom as mdom data = '&#174;' #Both accepted xml encodings for registered trademark data = '&reg;' text = mdom.Text() text.data = data print data print text.toxml() But because when I print text.toxml(), the ampersands are being escaped, I get this output: &reg; &amp;reg; My question is, does anybody know of a way that I can force the ampersands not to be escaped in the output, so that I can have my special character reference carry through to the XML document? Basically, for this node, I want print text.toxml() to produce output of &reg; or &#174; in a happy and cooperative way! EDIT 1: By the way, if minidom actually doesn't have this capacity, I am perfectly happy using another module that you can recommend which does. EDIT 2: As Hugh suggested, I tried using data = u'®' (while also using data # -*- coding: utf-8 -*- Python source tags). This almost helped in the sense that it actually caused the ® symbol itself to be outputted to my xml. This is actually not the result I am looking for. As you may have guessed by now (and perhaps I should have specified earlier) this xml document happens to be an HTML page, which needs to work in a browser. So having ® in the document ends up causing rubbish in the browser (® to be precise!). I also tried: data = unichr(174) text.data = data.encode('ascii','xmlcharrefreplace') print text.toxml() But of course this lead to the same origional problem where all that happens is the ampersand gets escaped by .toxml(). My ideal scenario would be some way of escaping the ampersand so that the XML printing function won't "escape" it on my behalf for the document (in other words, achieving my original goal of having &reg; or &#174; appear in the document). Seems like soon I'm going to have to resort to regular expressions! EDIT 2a: Or perhaps not. Seems like getting my html meta information correct <META http-equiv="Content-Type" Content="text/html; charset=UTF-8"> could help, but I'm not sure yet how this fits in with the xml structure...
