• Converting plain text in SQL to hyperlink in Access

  - by manemawanna

  Hello, I've just started a new job my first since leaving University and as part of this my first task is to convert a wholly Access 2003 database to an Access front-end, SQL back-end. The Access database consists of a series of front end forms to add or review staff data, as part of this there is hyperlinks pointing to a photograph of the employee and there CV located on a shared drive. These were saved as hyperlinks within the Access DB. I have since converted the data in the Access DB to SQL and stored it in a database for me to test on, now as part of the data conversion the photo and CV locations were converted to nvarchar from hyperlink. I've done this using SSMA. My issue now is that I need to have these text links displayed and working as hyperlinks on the front end hidden behind the words "Photo" and "CV", but am unsure as to how to go about this, as in the past I've only ever used SQL and not Access. Any help or suggestions would be appreciated and if I've not been clear in any areas please feel free to ask questions and I'll try to clear anything up for you.

• Detect IE version in Javascript

  - by Chad Decker

  I want to bounce users of our web site to an error page if they're using a version of Internet Explorer prior to v9. It's just not worth our time and money to support IE pre-v9. Users of all other non-IE browsers are fine and shouldn't be bounced. Here's the proposed code: if(navigator.appName.indexOf("Internet Explorer")!=-1){ //yeah, he's using IE var badBrowser=( navigator.appVersion.indexOf("MSIE 9")==-1 && //v9 is ok navigator.appVersion.indexOf("MSIE 1")==-1 //v10, 11, 12, etc. is fine too ); if(badBrowser){ // navigate to error page } } Will this code do the trick? To head off a few comments that will probably be coming my way: [1] Yes, I know that users can forge their useragent string. I'm not concerned. [2] Yes, I know that programming pros prefer sniffing out feature-support instead of browser-type but I don't feel this approach makes sense in this case. I already know that all (relevant) non-IE browsers support the features that I need and that all pre-v9 IE browsers don't. Checking feature by feature throughout the site would be a waste. [3] Yes, I know that someone trying to access the site using IE v1 (or = 20) wouldn't get 'badBrowser' set to true and the warning page wouldn't be displayed properly. That's a risk we're willing to take. [4] Yes, I know that Microsoft has "conditional comments" that can be used for precise browser version detection. IE no longer supports conditional comments as of IE 10, rendering this approach absolutely useless. Any other obvious issues to be aware of? Thanks.

• PHP IF condition advise needed

  - by Jose David Garcia Llanos

  I'm using emails as username to login into a site being developed, now if a user updates their email from the profile page, how can i make sure that my email checking statement doesnt catch the user's email as already registered in the database. the page /* Now we will store the values submitted by form in variable */ $fullname=$_POST['fullname']; $dob=$_POST['dob']; $address=$_POST['address']; $myusername=$_POST['myusername']; $telephone=$_POST['telephone']; $queryuser=mysql_query("SELECT * FROM customer WHERE email='$myusername' "); $checkuser=mysql_num_rows($queryuser); if($checkuser != 0) { $Merr[]='&raquo; Sorry this email is already registered!'; } else {$insert_user=mysql_query("UPDATE CUSTOMER SET SYNTAX HERE"); Now these are the fields in question; (name, dob, address, email, telephone) VALUES ('$fullname', '$dob', '$address', '$myusername', '$telephone') As you can see if the user changes the login email then the syntax checks for the email being submitted against the database, however if the user leaves the email unchanged he will get the error because it is found in the database. I was thinking of something like; if($checkuser != 0) { if($myusername == $_POST['myusername']) (...dont show error.) but my php skills are limited. can anyone advise please, thanks

• Neo4j Reading data / performing shortest path calculations on stored data

  - by paddydub

  I'm using the Batch_Insert example to insert Data into the database How can i read this data back from the database. I can't find any examples of how i do this. public static void CreateData() { // create the batch inserter BatchInserter inserter = new BatchInserterImpl( "var/graphdb", BatchInserterImpl.loadProperties( "var/neo4j.props" ) ); Map<String,Object> properties = new HashMap<String,Object>(); properties.put( "name", "Mr. Andersson" ); properties.put( "age", 29 ); long node1 = inserter.createNode( properties ); properties.put( "name", "Trinity" ); properties.remove( "age" ); long node2 = inserter.createNode( properties ); inserter.createRelationship( node1, node2, DynamicRelationshipType.withName( "KNOWS" ), null ); inserter.shutdown(); } I would like to store graph data in the database, graph.makeEdge( "s", "c", "cost", (double) 7 ); graph.makeEdge( "c", "e", "cost", (double) 7 ); graph.makeEdge( "s", "a", "cost", (double) 2 ); graph.makeEdge( "a", "b", "cost", (double) 7 ); graph.makeEdge( "b", "e", "cost", (double) 2 ); Dijkstra<Double> dijkstra = getDijkstra( graph, 0.0, "s", "e" ); What is the best method to store this kind data with 10000's of edges. Then run the Dijskra algorighm to find shortest path calculations using the stored graph data.

• DjangoUnicodeDecodeError while storing pickle'd data.

  - by Jack M.

  I've got a simple dict object I'm trying to store in the database after it has been run through pickle. It seems that Django doesn't like trying to encode this error. I've checked with MySQL, and the query isn't even getting there before it is throwing the error, so I don't believe that is the problem. The dict I'm storing looks like this: { 'ordered': [ { 'value': u'First\xd1ame Last\xd1ame', 'label': u'Full Name' }, { 'value': u'123-456-7890', 'label': u'Phone Number' }, { 'value': u'[email protected]', 'label': u'Email Address' } ], 'cleaned_data': { u'Phone Number': u'123-456-7890', u'Full Name': u'First\xd1ame Last\xd1ame', u'Email Address': u'[email protected]' }, 'post_data': <QueryDict: { u'Phone Number': [u'1234567890'], u'Full Name_1': [u'Last\xd1ame'], u'Full Name_0': [u'First\xd1ame'], u'Email Address': [u'[email protected]'] }>, 'user': <User: itis> } The error that gets thrown is: 'utf8' codec can't decode bytes in position 52-53: invalid data. Position 52-53 is the first instance of \xd1 (Ñ) in the pickled data. So far, I've dug around StackOverflow and found a few questions where the database encoding for the objects was wrong. This doesn't help me because there is no MySQL query yet. This is happening before the database. Google also didn't help much when searching for unicode errors on pickled data. It is probably worth mentioning that if I don't use the Ñ, this code works fine.

• Visual Studio 2005 - OleDbConnection throws "Invalid authorization specification" in Form Designer,

  - by Jason Dagit

  I have a form with an OleDbConnection object on it. This form fails to load in the Form Designer with the message: One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes. Invalid authorization specification at ADODB.ConnectionClass.Open(String ConnectionString, String UserID, String Password, Int32 Options) ... (stack trace continues into user code) I've tracked this down to the OleDbConnection string. If I hardcode in the server IP, username/password/dbinstance into the constructor of the GUI form then the form will load in the designer. At run-time it is not an issue because we require the user to provide the login details. The question: Is it possible to use the OleDbConnection and the Form designer without supplying the database credentials in the source code of the form? For example, is there a property of the OleDbConnection or Form that I can set so that it doesn't need to access the database during Form design? My concern is that if we ever move the database server or change the login that the code will stop working in the designer.

• wix The directory is in the user profile but is not listed in the RemoveFile table

  I have the following configuration to delete and copy a file from WIX. <Directory Id='TARGETDIR' Name='SourceDir'> ... <Directory Id="AppDataFolder" Name="AppDataFolder"> <Directory Id="GleasonAppData" Name="Gleason" > <Directory Id="GleasonStudioAppData" Name="GleasonStudio"> <Directory Id="DatabaseAppData" Name ="Database"> <Directory Id="UserSandboxesAppData" Name="UserSandboxes" /> </Directory> </Directory> </Directory> </Directory> </Directory> <DirectoryRef Id="UserSandboxesAppData"> <Component Id="comp_deleteBackup" Guid="1f159f49-3029-4f46-b194-e42aabd40844"> <RemoveFile Id="RemoveBackup" Directory="UserSandboxesAppData" Name="DevelopmentBackUp.FDB" On="install" /> <RegistryKey Root="HKCU" Key="Software\Gleason\Database\RemoveBackup"> <RegistryValue Value="Removed" Type="string" KeyPath="yes" /> </RegistryKey> </Component> <Component Id="comp_createBackup" Guid="557badef-6d77-4c4e-aa5f-8d88cb5ef735"> <CopyFile Id="DBBackup" DestinationDirectory="UserSandboxesAppData" DestinationName="DevelopmentBackUp.FDB" SourceDirectory="UserSandboxesAppData" SourceName="Development.FDB" /> <RegistryKey Root="HKCU" Key="Software\Gleason\Database\CopyBackup"> <RegistryValue Value="Copied" Type="string" KeyPath="yes" /> </RegistryKey> </Component> </DirectoryRef> I get 4 errors related to ICE64--The directory 'xxx' is in the user profile but is not listed in the RemoveFile table. xxx={UserSandboxesAppData, DatabaseAppData, GleasonStudioAppData, GleasonAppData} Someone else had a very similar problem here: Directory xx is in the user profile but is not listed in the RemoveFile table. . But that solution did not help me. What do I need to change? Thank You, Venkat Rao

• How to localize an app on Google App Engine?

  - by Petri Pennanen

  What options are there for localizing an app on Google App Engine? How do you do it using Webapp, Django, web2py or [insert framework here]. 1. Readable URLs and entity key names Readable URLs are good for usability and search engine optimization (Stack Overflow is a good example on how to do it). On Google App Engine, key based queries are recommended for performance reasons. It follows that it is good practice to use the entity key name in the URL, so that the entity can be fetched from the datastore as quickly as possible. Currently I use the function below to create key names: import re import unicodedata def urlify(unicode_string): """Translates latin1 unicode strings to url friendly ASCII. Converts accented latin1 characters to their non-accented ASCII counterparts, converts to lowercase, converts spaces to hyphens and removes all characters that are not alphanumeric ASCII. Arguments unicode_string: Unicode encoded string. Returns String consisting of alphanumeric (ASCII) characters and hyphens. """ str = unicodedata.normalize('NFKD', unicode_string).encode('ASCII', 'ignore') str = re.sub('[^\w\s-]', '', str).strip().lower() return re.sub('[-\s]+', '-', str) This works fine for English and Swedish, however it will fail for non-western scripts and remove letters from some western ones (like Norwegian and Danish with their œ and ø). Can anyone suggest a method that works with more languages? 2. Translating templates Does Django internationalization and localization work on Google App Engine? Are there any extra steps that must be performed? Is it possible to use Django i18n and l10n for Django templates while using Webapp? The Jinja2 template language provides integration with Babel. How well does this work, in your experience? What options are avilable for your chosen template language? 3. Translated datastore content When serving content from (or storing it to) the datastore: Is there a better way than getting the *accept_language* parameter from the HTTP request and matching this with a language property that you have set with each entity?

• Receiving DB update events in .NET from SQLite

  - by Dan Tao

  I've recently discovered the awesomeness of SQLite, specifically the .NET wrapper for SQLite at http://sqlite.phxsoftware.com/. Now, suppose I'm developing software that will be running on multiple machines on the same network. Nothing crazy, probably only 5 or 6 machines. And each of these instances of the software will be accessing an SQLite database stored in a file in a shared directory (is this a bad idea? If so, tell me!). Is there a way for each instance of the app to be notifiied if one instance updates the database file? One obvious way would be to use the FileSystemWatcher class, read the entire database into a DataSet, and then ... you know ... enumerate through the entire thing to see what's new ... but yeah, that seems pretty idiotic, actually. Is there such a thing as a provider of SQLite updates? Does this even make sense as a question? I'm also pretty much a newbie when it comes to ADO.NET, so I might be approaching the problem from the entirely wrong angle.

• How to build n-layered web architecture with PHP?

  - by Alex

  I have a description and design of a website and I need to redesign it to allow for new requirements. The website's purpose is the offering of government's contracts and bidding opportunities for different businesses.I'm dealing with the 3-tier architecture PHP website comprising of the user-interface tier(client's web browser),business logic layer(Apache web server with PHP engine in it and a couple of applications running within a web server as well) and a database layer(local mysql database). Now,i need to redesign it to su???rt distributed n-tier architecture and specify how I would go about it.After long hours of research i came to this solution: business logic should be separated into presentation and purely business logic tier to allow for n-layer architecture(user-interface,presentation tier,b.logic and data tier).I have decided to use ??? just for the presentation(since the original existing website is in PHP) and use it within apache web server.In the business logic i want to use J2?? implementation technology instead of implementing it in PHP(i.e using Zend app.server and smarty template) cz J2EE can provide much more essential container services which are essential for business logic,its robustness,maintainability and different critical business operations which will be carried out by the g?v?rnment's website.So,particularly,i want to use J??ss app.server with ?J? business objects in it which would provide all the b.logic in java and would interact with the database and so forth.In order to connect PHP on a web server with java on app.server i'm gonna use PHP/Java bridge API (or maybe Quercus or SOAP is better?).Finally,i have my data tier with mysql which will communicate with b.logic via JD??.Payment system application in ???.server is gonna use S??? to talk with credit card company. From your professional point of view,does it sound like a good way of redesigning the original website to allow for n-tier architecture considering the specifics of the website and the criticality of its operations?(payment system is included in it)or u would personally prefer to use PHP business objects for business logic as well instead of J2EE?If you have any wiser recommendation or some alternative,please let me know what is right or wrong in my current solution. H??? to hear your professional advice very s??n (I'm new to the area of web development) Thanks in advance

• 1D Function into 2D Function Interpolation

  - by Drazick

  Hello. I have a 1D function which I want to interpolate into 2D function. I know the function should have "Polar Symmetry". Hence I use the following code (Matlab Syntax): Assuming the 1D function is LSF of the length 15. [x, y] = meshgrid([-7:7]); r = sqrt(x.^2 + y.^2); PSF = interp1([-7:7], LSF, r(:)); % Sometimes using 'spline' option, same results. PSF = reshape(PSF, [7, 7]); I have few problems: 1. Got some overshoot at the edges (As there some Extrapolation). 2. Can't enforce some assumptions (Monotonic, Non Negative). Is there a better Interpolation method for those circumstances? I couldn't find "Lanczos" based interpolation I can use the same way as interp1 (For a certain vector of points, in "imresize" you can only set the length). Is there such function anywhere? Has anyone encountered a function which allows enforcing some assumptions (Monotonically Decreasing, Non Negative, etc..). Thanks.

• forward/strong enum in VS2010

  - by Noah Roberts

  At http://blogs.msdn.com/vcblog/archive/2010/04/06/c-0x-core-language-features-in-vc10-the-table.aspx there is a table showing C++0x features that are implemented in 2010 RC. Among them are listed forwarding enums and strongly typed enums but they are listed as "partial". The main text of the article says that this means they are either incomplete or implemented in some non-standard way. So I've got VS2010RC and am playing around with the C++0x features. I can't figure these ones out and can't find any documentation on these two features. Not even the simplest attempts compile. enum class E { test }; int main() {} fails with: 1e:\dev_workspace\experimental\2010_feature_assessment\2010_feature_assessment\main.cpp(518): error C2332: 'enum' : missing tag name 1e:\dev_workspace\experimental\2010_feature_assessment\2010_feature_assessment\main.cpp(518): error C2236: unexpected 'class' 'E'. Did you forget a ';'? 1e:\dev_workspace\experimental\2010_feature_assessment\2010_feature_assessment\main.cpp(518): error C3381: 'E' : assembly access specifiers are only available in code compiled with a /clr option 1e:\dev_workspace\experimental\2010_feature_assessment\2010_feature_assessment\main.cpp(518): error C2143: syntax error : missing ';' before '}' 1e:\dev_workspace\experimental\2010_feature_assessment\2010_feature_assessment\main.cpp(518): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== int main() { enum E : short; } Fails with: 1e:\dev_workspace\experimental\2010_feature_assessment\2010_feature_assessment\main.cpp(513): warning C4480: nonstandard extension used: specifying underlying type for enum 'main::E' 1e:\dev_workspace\experimental\2010_feature_assessment\2010_feature_assessment\main.cpp(513): error C2059: syntax error : ';' ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== So it seems it must be some totally non-standard implementation that has allowed them to justify calling this feature "partially" done. How would I rewrite that code to access the forwarding and strong type feature?

• How can I stop an auto-generated Linq to SQL class from loading ALL data?

  - by Gary McGill

  DUPLICATE of http://stackoverflow.com/questions/2433422/how-can-i-stop-an-auto-generated-linq-to-sql-class-from-loading-all-data post answers there! I have an ASP.NET MVC project, much like the NerdDinner tutorial example. (I'm using MVC 2, but followed the NerdDinner tutorial in order to create it). As per the instructions in part 3 of the tutorial, I've created a Linq-to-SQL model of my database by creating a "Linq to SQL Classes" (.dbml) surface, and dropping my database tables onto it. The designer has automatically added relationships between the generated classes based on my database tables. Let's say that my classes are as per the NerdDinner example, so I have Dinner and RSVP tables, where each Dinner record is associated with many RSVP records - hence in the generated classes, the Dinner object has a RSVPs property which is a list of RSVP objects. My problem is this: it appears (and I'd be gladly proved wrong on this) that as soon as I access a Dinner object, it's loading all of the corresponding RSVP objects, even if I don't use the RSVPs member. First question: is this really the default behavior for the generated classes? In my particular situation, the object graph contains many more tables (which have an order of magnitude more records), and so this is disastrous behaviour - I'd be loading tons of data when all I want to do is show the details of a single parent record. Second question: are there any properties exposed through the designer UI that would let me modify this behavior? (I can't find any). Third question: I've seen a description of how to control the loading of related records in a DataContext by using a DataShape object associated with the DataContext. Is that what I'm meant to do, and if so are there any tutorials like the NerdDinner one that would show not only how to do it, but also suggest a 'pattern' for normal use?

• Curve fitting: Find the smoothest function that satisfies a list of constraints.

  - by dreeves

  Consider the set of non-decreasing surjective (onto) functions from (-inf,inf) to [0,1]. (Typical CDFs satisfy this property.) In other words, for any real number x, 0 <= f(x) <= 1. The logistic function is perhaps the most well-known example. We are now given some constraints in the form of a list of x-values and for each x-value, a pair of y-values that the function must lie between. We can represent that as a list of {x,ymin,ymax} triples such as constraints = {{0, 0, 0}, {1, 0.00311936, 0.00416369}, {2, 0.0847077, 0.109064}, {3, 0.272142, 0.354692}, {4, 0.53198, 0.646113}, {5, 0.623413, 0.743102}, {6, 0.744714, 0.905966}} Graphically that looks like this: We now seek a curve that respects those constraints. For example: Let's first try a simple interpolation through the midpoints of the constraints: mids = ({#1, Mean[{#2,#3}]}&) @@@ constraints f = Interpolation[mids, InterpolationOrder->0] Plotted, f looks like this: That function is not surjective. Also, we'd like it to be smoother. We can increase the interpolation order but now it violates the constraint that its range is [0,1]: The goal, then, is to find the smoothest function that satisfies the constraints: Non-decreasing. Tends to 0 as x approaches negative infinity and tends to 1 as x approaches infinity. Passes through a given list of y-error-bars. The first example I plotted above seems to be a good candidate but I did that with Mathematica's FindFit function assuming a lognormal CDF. That works well in this specific example but in general there need not be a lognormal CDF that satisfies the constraints.

• Entity Framework query

  - by carter-boater

  Hi all, I have a piece of code that I don't know how to improve it. I have two entities: EntityP and EntityC. EntityP is the parent of EntityC. It is 1 to many relationship. EntityP has a property depending on a property of all its attached EntityC. I need to load a list of EntityP with the property set correctly. So I wrote a piece of code to get the EntityP List first.It's called entityP_List. Then as I wrote below, I loop through the entityP_List and for each of them, I query the database with a "any" function which will eventually be translated to "NOT EXIST" sql query. The reason I use this is that I don't want to load all the attached entityC from database to memory, because I only need the aggregation value of their property. But the problem here is, the looping will query the databae many times, for each EntityP! So I am wondering if anybody can help me improve the code to query the database only once to get all the EntityP.IsAll_C_Complete set, without load EntityC to memory. foreach(EntityP p in entityP_List) { isAnyNotComoplete = entities.entityC.Any(c => c.IsComplete==false && c.parent.ID == p.ID); p.IsAll_C_Complete = !isAnyNotComoplete; } Thank you very much!

I got the following steps, but they are not working: 1 - Clone STLport repository using: git clone git://stlport.git.sourceforge.net/gitroot/stlport/stlport 2 - Configure environment using : ./configure --target=arm-eabi --with-extra-cxxflags="-fshort-enums" --with-extra-cflags="-fshort-enums" 3 - From src directory build it using make SYSROOT"{MY NDK path}/platforms/android-5/arch-arm/" release-static But I got the following errors: In file included from ../stlport/stl/_alloc.h:45, from ../stlport/memory:29, from dll_main.cpp:41: ../stlport/stl/_new.h:45:24: error: new: No such file or directory In file included from ../stlport/stl/_limits.h:36, from ../stlport/limits:29, from dll_main.cpp:48: ../stlport/stl/_cwchar.h:26:30: error: cstddef: No such file or directory In file included from ../stlport/stl/_utility.h:35, from ../stlport/utility:35, from dll_main.cpp:40: ../stlport/type_traits:889: error: 'declval' was not declared in this scope ../stlport/type_traits:889: error: expected primary-expression before '>' token ../stlport/type_traits:889: error: expected primary-expression before ')' token ../stlport/type_traits:889: error: 'declval' was not declared in this scope ../stlport/type_traits:889: error: expected primary-expression before '>' token ../stlport/type_traits:889: error: expected primary-expression before ')' token ../stlport/type_traits:889: error: ISO C++ forbids declaration of 'decltype' with no type ../stlport/type_traits:889: error: ISO C++ forbids in-class initialization of non-const static member 'decltype' ../stlport/type_traits:889: error: template declaration of 'int std::tr1::detail::decltype' ../stlport/type_traits:942: error: ISO C++ forbids declaration of 'decltype' with no type ../stlport/type_traits:942: error: ISO C++ forbids in-class initialization of non-const static member 'decltype' ../stlport/type_traits:942: error: template declaration of 'int std::tr1::detail::decltype' make: *** [obj/arm-eabi-gcc/so/dll_main.o] Error 1 Is there any include dir or configuration I´m missing?

• DDD and MVC: Difference between 'Model' and 'Entity'

  - by Nathan Loding

  I'm seriously confused about the concept of the 'Model' in MVC. Most frameworks that exist today put the Model between the Controller and the database, and the Model almost acts like a database abstraction layer. The concept of 'Fat Model Skinny Controller' is lost as the Controller starts doing more and more logic. In DDD, there is also the concept of a Domain Entity, which has a unique identity to it. As I understand it, a user is a good example of an Entity (unique userid, for instance). The Entity has a life-cycle -- it's values can change throughout the course of the action -- and then it's saved or discarded. The Entity I describe above is what I thought Model was supposed to be in MVC? How off-base am I? To clutter things more, you throw in other patterns, such as the Repository pattern (maybe putting a Service in there). It's pretty clear how the Repository would interact with an Entity -- how does it with a Model? Controllers can have multiple Models, which makes it seem like a Model is less a "database table" than it is a unique Entity. So, in very rough terms, which is better? No "Model" really ... class MyController { public function index() { $repo = new PostRepository(); $posts = $repo->findAllByDateRange('within 30 days'); foreach($posts as $post) { echo $post->Author; } } } Or this, which has a Model as the DAO? class MyController { public function index() { $model = new PostModel(); // maybe this returns a PostRepository? $posts = $model->findAllByDateRange('within 30 days'); while($posts->getNext()) { echo $posts->Post->Author; } } } Both those examples didn't even do what I was describing above. I'm clearly lost. Any input?

• "Replay" the steps needed to recreate an error

  - by David

  I am going to create a typical business application that will be used by a few hundred consultants. Normally, the consultants would be presented with an error message with a standard text. As the application will be a complicated one with lots of changes being made to it constantly I would like the following: When an error message is presented, the user has the option to "send" the error message to the developers. The developers should be able to open the incoming file in i.e. Eclipse and debug the steps of the last 10 minutes of work step by step (one line at a time if they want to). Everything should be transparent, meaning that they for example should be able to see the return values of calls to the database. Are there any solutions that offer such functionality today, my preferred language is Python or also Java. I know that there will be a huge performance hit because of such functionality, but that is acceptable as this kind of software is not performance sensitive. It would be VERY nice if the database also had a cronology so that one could query the database for values that existed at the exact time that a specific line of code was run in the application, leading up to the bug.

• PHP PDO SQL Server Select statement not replacing question marks

  - by Metropolis

  Awhile ago I wrote a database class which uses PDO in order to connect to SQL Server databases and also to MySQL databases. It has always replaced the question marks fine when using it on the MySQL databases, but for the SQL Server database I had to create a work around which basically replaces the question marks manually. Here is the code for that. if($this->getPDODriver() == 'odbc' && !empty($values_a) && substr_count($query_s, "?") > 0) { $query_s = preg_replace(array_fill(0, substr_count($query_s, "?"), '/\?/'), $values_a, $query_s, 1); $values_a = NULL; } Now, I understand that this completely defeats the purpose of the question marks and PDO, but it has been working fine for me. What I would like to do now though, is find out why the question marks are not getting replaced in the first place, and remove this workaround. If I have a select statement like the following SELECT * FROM database WHERE value = ? That is what the query looks like when I go to prepare it, but when I display the query results, it is a blank array. Just remember, this class is working fine with MySQL, and it is working fine with the work around above. So I know it has something to do with the question marks.

• How to add a user to a SharePoint group programatically - Access is Denied

  - by Josh

  I have tried and tried to add a user to a SharePoint group using C# programatically (using a non-site admin). If I am logged in as a site admin, it works fine... but, if I am logged in as a non-site admin then I get an access is denied error. After doing some investigation I found that I needed to either "impersonate" the user (which didn't seem to work) or "ensure the user", so I have ended up at this code (which has worked for some people). Can some help explain to me why the following does not work and still gives me an Access is Denied error? SPSecurity.RunWithElevatedPrivileges(delegate() { using (SPSite site = new SPSite(SPControl.GetContextSite(HttpContext.Current).Url)) //have also tried passing in the ID - doesn't make a difference { using (SPWeb web = site.OpenWeb()) { web.AllowUnsafeUpdates = true; // add user to group SPGroup group = this.Web.Groups[groupList.Items[i].Value]; SPUser spUser = web.EnsureUser(provider + ":" + user.UserName); //provider is previously defined spUser.Email = user.Email; spUser.Name = txtFullName.Text; group.AddUser(spUser); // update group.Update(); } } }

• Glassfish: Defining Custom JNDI Names for Session Beans

  - by Adeel Ansari

  Background: Want to use GF3 in development, where as actual SIT, UAT, and production is using WAS. Problem: With the remote session beans everything is good to go, as GF3 gives a non-standard JNDI name, which is same as what WAS suggests, i.e. an absolute class name. Now for the local session beans WAS use the same absolute class name but with the prefix, i.e. ejblocal:. Whereas GF3 doesn't give any non-standard JNDI name for local session beans. GF3 came up with only portable name, java:global/..I need to find a way so I can use the same names for both. I am using EJB 3.0, WAS 7.9, and Glassfish 3. Don't have any xml confiuration for ejbs. Using Spring to inject the bean in Struts2 actions. With remote interfaces both servers are okay and agreed on a single convention, but for locals they differ. Is there any solution for this? Or just sun-ejb-jar.xml will solve it? Thanks.

• Error 1053: the service did not respond to the start or control request in a timely fashion

  - by deejjaayy

  i know this is very much a "how long is a piece of string" type of question, however i have recently inherited a couple of applications that run as windows services, and i am having problems providing a gui (accessible from a context menu in system tray) with both of them. before you ask, the reason why we need a gui for a windows service is in order to be able to re-configure the behaviour of the windows service(s) without resorting to stopping/re-starting. my code works fine in debug mode, and i get the context menu come up, and everything behaves correctly etc. when i install the service via "installutil" using a named account (i.e., not Local System Account), the service runs fine, but doesn't display the icon in the system tray (i know this is normal behaviour because i don't have the "interact with desktop" option). here is the problem though - when i choose the "LocalSystemAccount" option, and check the "interact with desktop" option, the service takes AGES to start up for no obvious reason, and i just keep getting "Could not start the ... service on Local Computer. Error 1053: the service did not respond to the start or control request in a timely fashion". incidentally, i increased the windows service timeout from the default 30 seconds to 2 minutes via a registry hack (see http://support.microsoft.com/kb/824344, search for TimeoutPeriod in section 3), however the service start up still times out. my first question is - why might the "Local System Account" login takes SOOOOO MUCH LONGER than when the service logs in with the non-LocalSystemAccount, causing the windows service time-out? what's could the difference be between these two to cause such different behaviour at start up? secondly - taking a step back, all i'm trying to achieve, is simply a windows service that provides a gui for configuration - I'd be quite happy to run using the non-Local System Account (with named user/pwd), if I could get the service to interact with the desktop (that is, have a context menu available from the system tray). is this possible, and if so how? any pointers to the above questions would be very much appreciated! thanks in advance for your help.
