• Connecting to a network drive programmatically and caching credentials

  - by Chris Doggett

  I'm finally set up to be able to work from home via VPN (using Shrew as a client), and I only have one annoyance. We use some batch files to upload config files to a network drive. Works fine from work, and from my team lead's laptop, but both of those machines are on the domain. My home system is not, and won't be, so when I run the batch file, I get a ton of "invalid drive" errors because I'm not a domain user. The solution I've found so far is to make a batch file with the following: explorer \\MACHINE1 explorer \\MACHINE2 explorer \\MACHINE3 Then manually login to each machine using my domain credentials as they pop up. Unfortunately, there are around 10 machines I may need to use, and it's a pain to keep entering the password if I missed one that a batch file requires. I'm looking into using the answer to this question to make a little C# app that'll take the login info once and login programmatically. Will the authentication be shared automatically with Explorer, or is there anything special I need to do? If it does work, how long are the credentials cached? Is there an app that does something like this automatically? Unfortunately, domain authentication via the VPN isn't an option, according to our admin. EDIT: If there's a way to pass login info to Explorer via the command line, that would be even easier using Ruby and highline.

• CSRF Protection in AJAX Requests using MVC2

  - by mnemosyn

  The page I'm building depends heavily on AJAX. Basically, there is just one "page" and every data transfer is handled via AJAX. Since overoptimistic caching on the browser side leads to strange problems (data not reloaded), I have to perform all requests (also reads) using POST - that forces a reload. Now I want to prevent the page against CSRF. With form submission, using Html.AntiForgeryToken() works neatly, but in AJAX-request, I guess I will have to append the token manually? Is there anything out-of-the box available? My current attempt looks like this: I'd love to reuse the existing magic. However, HtmlHelper.GetAntiForgeryTokenAndSetCookie is private and I don't want to hack around in MVC. The other option is to write an extension like public static string PlainAntiForgeryToken(this HtmlHelper helper) { // extract the actual field value from the hidden input return helper.AntiForgeryToken().DoSomeHackyStringActions(); } which is somewhat hacky and leaves the bigger problem unsolved: How to verify that token? The default verification implementation is internal and hard-coded against using form fields. I tried to write a slightly modified ValidateAntiForgeryTokenAttribute, but it uses an AntiForgeryDataSerializer which is private and I really didn't want to copy that, too. At this point it seems to be easier to come up with a homegrown solution, but that is really duplicate code. Any suggestions how to do this the smart way? Am I missing something completely obvious?

• SQL Server Search Proper Names Full Text Index vs LIKE + SOUNDEX

  - by Matthew Talbert

  I have a database of names of people that has (currently) 35 million rows. I need to know what is the best method for quickly searching these names. The current system (not designed by me), simply has the first and last name columns indexed and uses "LIKE" queries with the additional option of using SOUNDEX (though I'm not sure this is actually used much). Performance has always been a problem with this system, and so currently the searches are limited to 200 results (which still takes too long to run). So, I have a few questions: Does full text index work well for proper names? If so, what is the best way to query proper names? (CONTAINS, FREETEXT, etc) Is there some other system (like Lucene.net) that would be better? Just for reference, I'm using Fluent NHibernate for data access, so methods that work will with that will be preferred. I'm using SQL Server 2008 currently. EDIT I want to add that I'm very interested in solutions that will deal with things like commonly misspelled names, eg 'smythe', 'smith', as well as first names, eg 'tomas', 'thomas'. Query Plan |--Parallelism(Gather Streams) |--Nested Loops(Inner Join, OUTER REFERENCES:([testdb].[dbo].[Test].[Id], [Expr1004]) OPTIMIZED WITH UNORDERED PREFETCH) |--Hash Match(Inner Join, HASH:([testdb].[dbo].[Test].[Id])=([testdb].[dbo].[Test].[Id])) | |--Bitmap(HASH:([testdb].[dbo].[Test].[Id]), DEFINE:([Bitmap1003])) | | |--Parallelism(Repartition Streams, Hash Partitioning, PARTITION COLUMNS:([testdb].[dbo].[Test].[Id])) | | |--Index Seek(OBJECT:([testdb].[dbo].[Test].[IX_Test_LastName]), SEEK:([testdb].[dbo].[Test].[LastName] >= 'WHITDþ' AND [testdb].[dbo].[Test].[LastName] < 'WHITF'), WHERE:([testdb].[dbo].[Test].[LastName] like 'WHITE%') ORDERED FORWARD) | |--Parallelism(Repartition Streams, Hash Partitioning, PARTITION COLUMNS:([testdb].[dbo].[Test].[Id])) | |--Index Seek(OBJECT:([testdb].[dbo].[Test].[IX_Test_FirstName]), SEEK:([testdb].[dbo].[Test].[FirstName] >= 'THOMARþ' AND [testdb].[dbo].[Test].[FirstName] < 'THOMAT'), WHERE:([testdb].[dbo].[Test].[FirstName] like 'THOMAS%' AND PROBE([Bitmap1003],[testdb].[dbo].[Test].[Id],N'[IN ROW]')) ORDERED FORWARD) |--Clustered Index Seek(OBJECT:([testdb].[dbo].[Test].[PK__TEST__3214EC073B95D2F1]), SEEK:([testdb].[dbo].[Test].[Id]=[testdb].[dbo].[Test].[Id]) LOOKUP ORDERED FORWARD) SQL for above: SELECT * FROM testdb.dbo.Test WHERE LastName LIKE 'WHITE%' AND FirstName LIKE 'THOMAS%' Based on advice from Mitch, I created an index like this: CREATE INDEX IX_Test_Name_DOB ON Test (LastName ASC, FirstName ASC, BirthDate ASC) INCLUDE (and here I list the other columns) My searches are now incredibly fast for my typical search (last, first, and birth date).

• Ldap query returns null result when deployed.

  - by Trey Carroll

  I'm using a very simple Ldap query in my asp.net mvc 2.0 site: String ldapPath = ConfigReader.LdapPath; String emailAddress = null; try { DirectorySearcher search = new DirectorySearcher(ConfigReader.LdapPath); search.Filter = String.Format("(&(objectClass=user)(objectCategory=person)(objectSid={0})) ", securityIdentifierValue); // add the mail property to the list of props to retrieve search.PropertiesToLoad.Add("mail"); var result = search.FindOne(); if (result == null) { throw new Exception("Ldap Query with filter:" + search.Filter.ToString() + " returned a null value (no match found)"); } else { emailAddress = result.Properties["mail"][0].ToString(); } } catch (ArgumentOutOfRangeException aoorEx) { throw new Exception( "The query could not find an email for this user."); } catch (Exception ex) { //_log.Error(string.Format("======!!!!!! ERROR ERROR ERROR !!!!! in LdapLookupUtil.cs getEmailFromLdap Exception: {0}", ex)); throw ex; } return emailAddress; It works fine on my localhost machine. It works fine when I run it in VS2010 on the server. It always returns a null result when deployed. Here is my web.config: Asp.Net Configuration option in Visual Studio. A full list of settings and comments can be found in machine.config.comments usually located in \Windows\Microsoft.Net\Framework\v2.x\Config -- section enables configuration of the security authentication mode used by ASP.NET to identify an incoming user. -- <!-- -- section enables configuration of what to do if/when an unhandled error occurs during the execution of a request. Specifically, it enables developers to configure html error pages to be displayed in place of a error stack trace. -- I'm running it under the default app pool. Does anybody see the problem? This is driving me crazy!

• iTextSharp Conversion from Table to pdfPTable

  - by Al.

  I have an old ASP.NET project originally done in ASP.NET 1.1 w/ iText.NET and converted to .NET 2.0 and iTextSharp 4.1.6.0. It uses lots of Table (I'm assuming pdfptable wasn't an option at the time it was created.) I am trying to convert this code to use the latest iTextSharp 5.0.0 dll and now see Table and cell have been removed. I started converting it anyway and soon found there is no equivalent to a lot of the functionality that Table offered. Mainly AddCell no longer allows a col,row setting. There are literally thousands of these calls in this code and the posibility of changing it to generate linearly row by row looks hopeless at the moment. The current code looks something like: Dim myTable As New Table(NumReq + 2, IngDS.Tables(0).Rows.Count + 3) myTable.SetWidths(Width) myTable.Width = 100 myTable.Padding = 2 myCell = New Cell(New Phrase("Some Text", New iTextSharp.text.Font(iTextSharp.text.Font.HELVETICA, 8, iTextSharp.text.Font.NORMAL, iTextSharp.text.Color.BLACK))) myCell.SetHorizontalAlignment(Element.ALIGN_RIGHT) myCell.GrayFill = 0.75 myTable.AddCell(myCell, Row, Col) myCell = New Cell(New Phrase("Other Text",New iTextSharp.text.Font(iTextSharp.text.Font.HELVETICA, 8, iTextSharp.text.Font.NORMAL, iTextSharp.text.Color.BLACK))) myCell.GrayFill = 0.75 myTable.AddCell(myCell, Row, Col+1) Before I embark down that road I was hoping someone would be able to point me in a direction that I'm just totally missing that will make this conversion much more simple. Any ideas? Thanks.

• Best way to pass image to server?

  - by Chris

  I have an SL3 application that needs to be able to pass an image to the server, and then the server will generate a PDF file with the image in it, and display it to the user. What I already have in place are the following: (1) Code to convert image to byte array (2) Code to generate PDF file with image The main problem that I am running into is the following: In order to bypass the pop-up blocker, which is a requirement for my application, I am using the following code: var button = new NavigationButton(); button.NavigateUri = new Uri("http://localhost:3616/PrintReport.aspx?ReportIndex=11&ActionType=Get&ReportIdentifier=" + reportIdentifier.ToString() + ""); button.TargetName = "_blank"; button.PerformClick(); Initially, I would pass the image to a WCF web service (as a byte array), and then "navigate" to the ASP.NET page that would display the report. However, if I do this, then I can not use my custom HyperlinkButton class, and, certain browsers, including Safari, will block a new window from opening up. Therefore, it appears that the only option is to use the HyperlinkButton class. What I need to be able to do is to somehow pass the image, as a byte array or some other data type, to the server, such that it can temporarily store the image, even if it is in a server variable, and then immediately retrieve it when I navigate to the PrintReport.aspx page. If I upload the image to an ASP.NET form and then use the HyperlinkButton class to navigate to the PrintReport page, it doesn't work, as the app navigates to the PrintReport page before the system has finished uploading the image. I can't pass it to a web service, as that would require that I navigate to the PrintReport.aspx page in the callback code of the web method that I would be passing the image to, and the HyperlinkButton will not allow that, based on security rules. Any help or ideas would be appreciated. Thanks. Chris

• Multiple autocompletes on same form in socialengine

  - by Mirza Awais

  I am quite new to socialegine module development. I want to use multiple autocomplets on my one form. I have no problem of showing multiple auto completes but problem comes when one selects options from auto complete. I have seen that autocompet.js uses id toValues to show selected option from autocomlte. So if there is only one autocomplete on one form then we can have one element as toValues to show the selected value. But if we have multiple auto completes then how to show the selected item of each auto complete as separately? Using the following code for autocomplete en4.core.runonce.add(function() { new Autocompleter.Request.JSON('to', '<?php echo $this->url(array('module' => 'localspots', 'controller' => 'lookup', 'action' => 'city'), 'default', true) ?>', { 'minLength': 2, 'delay' : 1, 'selectMode': 'pick', 'autocompleteType': 'message', 'multiple': false, 'className': 'message-autosuggest', 'filterSubset' : true, 'tokenFormat' : 'object', 'tokenValueKey' : 'label', 'injectChoice': function(token){ console.log(token.type); var choice = new Element('li', {'class': 'autocompleter-choices', 'html': token.photo, 'id':token.label}); new Element('div', {'html': this.markQueryValue(token.label),'class': 'autocompleter-choice'}).inject(choice); this.addChoiceEvents(choice).inject(this.choices); choice.store('autocompleteChoice', token); }, onPush : function(){ if( $('toValues').value.split(',').length >= maxRecipients ){ $('to').disabled = true; $('to').setAttribute("class", "disabled"); } }, }); });

• Retrieving many huge sized EPS files and converting them to JPEG in ASP.NET application

  - by Ashish Gupta

  I have many (600) EPS files(300 KB - 1 MB) in database. In my ASP.NET application (using ASP.NET 4.0) I need to retrieve them one by one and call a web service which would convert the content to the JPEG file and update the database (JPEGContent column with the JPEG content). However, retrieving the content for 600 of them itself takes too long from the SQL management studio itself (takes 5 minutes for 10 EPS contents). So I have two issues:- 1) How to get the EPS content ( unfortunately, selecting certain number of content is not an option :-( ):- Approach 1:- foreach(var DataRow in DataTable.Rows) { // get the Id and byte[] of EPS // Call the web method to convert EPS content to JPEG which would also update the database. } or foreach(var DataRow in DataTable.Rows) { // get only the Id of EPS // Hit database to get the content of EPS // Call the web method to convert EPS content to JPEG which would also update the database. } or Any other approach? 2) Converting EPS to JPEG using a web method for 600 contents. Ofcourse, each call would be a long running operation. Would task parellel library (TPL) be a better way to achieve this? Also, is doing the entire thing in a SQL CLR function a good idea?

• How does VS 2005 provide history across all TFS Team Projects when tf.exe cannot?

  - by AakashM

  In Visual Studio 2005, in the TFS Source Control Explorer, these is a top-level node for the TFS Server itself, with a child node for each Team Project. Right-clicking either the server node or the node for a Team Project gives a context menu on which there is a View History item. Selecting this gives you a History window showing the last 200 or so changesets, either for the specific Team Project chosen, or across all Team Projects. It is this history across all Team Projects that I am wondering about. The command-line tf.exe history command provides (as I understand it) basically the same functionality as is provided by the VS TFS Source Control plug-in. But I cannot work out how to get tf.exe history to provide this across-all-Team-Projects history. At a command line, supposing I have C:\ mapped as the root of my workspace, and Foo, Bar, and Baz as Team Projects, I can do C:\> tf history Foo /recursive /stopafter:200 to get the last 200 changesets that affected Team Project Foo; or from within a Team Project folder C:\Bar> tf history *.* /recursive /stopafter:200 which does the same thing for Team Project Bar - note that the wildcard *.* is allowed here. However, none of these work (each gives the error message shown): C:\> tf history /recursive /stopafter:200 The history command takes exactly one item C:\> tf history *.* /recursive /stopafter:200 Unable to determine the source control server C:\> tf history *.* /server:servername /recursive /stopafter:200 Unable to determine the workspace I don't see an option in the docs for tf for specifying a workspace; it seems to only want to determine it from the current folder. So what is VS 2005 doing? Is it internally doing a history on each Team Project in turn and then sticking the results together?? note also that I have tried with Power Tools; tfpt history from the command line gives exactly the same error messages seen here

• Updating permissions on Amazon S3 files that were uploaded via JungleDisk

  - by Simon_Weaver

  I am starting to use Jungle Disk to upload files to an Amazon S3 bucket which corresponds to a Cloudfront distribution. i.e. I can access it via an http:// URL and I am using Amazon as a CDN. The problem I am facing is that Jungle Disk doesn't set 'read' permissions on the files so when I go to the corresponding URL in a browser I get an Amazon 'AccessDenied' error. If I use a tool like BucketExplorer to set the ACL then that URL now returns a 200. I really really like the simplicity of dragging files to a network drive. JungleDisk is the best program I've found to do this reliably without tripping over itself and getting confused. However it doesn't seem to have an option to make the files read-able. I really don't want to have to go to a different tool (especially if i have to buy it) to just change the permissions - and this seems really slow anyway because they generally seem to traverse the whole directory structure. JungleDisk provides some kind of 'web access' - but this is a paid feature and I'm not sure if it will work or not. S3 doesn't appear to propagate permissions down which is a real pain. I'm considering writing a manual tool to traverse my tree and set everything to 'read' but I'd rather not do this if this is a problem someone else has already solved.

• CSS Parser - Insert mtimes

  - by brad

  What command line tool can I use to automatically insert mtimes into urls in my css files for the purposes of breaking the cache? /* before */ .example { background: url(example.jpg); } /* after */ .example { background: url(example.jpg?1271298451); } Also, I would like this tool to spit out the latest mtime as the css files mtime. (If the css file is still cached then the new urls will not get to the client.) In searching the web, I have found very few tools that can do this. I am even considering rolling my own, but have found very little in the way of css parsers that are actively maintained. A candidate should be: fast (I don't want to wait 30 seconds on deployment) command line accessible (something like "cat foo.css bar.css | cssmtime out.css") What I've found so Far yui compressor - initially I thought I would extend the yui compressor to do this, but found that it is implemented as a bunch of regex's and not a parser. csstidy - last release was in 2007 and development has been suspended, but does have an option for inserting mtimes (also written in php, something I have no experience in) cssutils - python sac implementation - seems to be actively maintained, but also seems like overkill for my needs. Also, written in python which I have experience with csspool - ruby sac implementation - I don't know much ruby, but would like to learn other sac implementations - There are several java implementations, and a c implementation neither of which I know much about What's your experience? Have you used any of these libraries? Was the experience positive? Would you recommend I go with them for my purposes?

• RegAsm for Class Library Used in VB6 Application

  - by michael.lukatchik

  To be short and to the point, I've built a C# class library that is both COM-Visible and Registered for COM Interop. I've compiled the library, which resulted in the generation of .dll and .tlb files. I have another machine that's running a VB6 application. So, I copied the .dll and .tlb files over to C:/Windows/system32 folder on the machine. I then registered those files using the following: C:\Windows\Microsoft.NET\Framework\v2.0.50727\RegAsm C:\Windows\system32\TestClass.dll /tlb:TestClass.tlb After the files were registered successfully, I added a project reference to the Test.tlb file from inside my VB6 app, then I tried to invoke a method in my new referenced class like so: Dim myObject As TestNamespace.TestClass Set myObject = New TestNamespace.TestClass MsgBox (myObject.TestMethod()) It doesn't work, and I receive a -2147024894 Automation Error. I've read that I shouldn't install the dll into a private folder like system32. I should either be registering in the GAC or I should be registering in another location using the "/codebase" option: C:\Windows\Microsoft.NET\Framework\v2.0.50727\RegAsm C:\TestClass.dll /tlb:TestClass.tlb /codebase Is there any reason I shouldn't be using system32? Past devs that have worked on this project have placed assembly files used by this VB6 project into system32 and there haven't seemed to be any issues. When I register my dll in the system32 location, I get the Automation Error. When I register my dll in another location (i.e. C:/), the method call into my class library from VB6 works as expected. What gives? I should mention that we will NOT be using the GAC to register any DLL's. That's just the way it is. Any help is appreciated. Mike

• autoconf libtool library linker path incorrect (need drive-letter) for MinGW ld.exe in Cygwin

  - by Tam Toucan

  I use autoconf and when the target is mingw I was using the -mno-cygwin flag. This has been removed so I'm trying to using the mingw tool chain. The problem is the linker isn't finding my libraries /bin/sh ../../../libtool --tag=CXX --mode=link mingw32-g++ -g -Wall -pedantic -DNOMINMAX -D_REENTRANT -DWIN32 -I /usr/local/include/w32api -L/usr/local/lib/w32api -o testRandom.exe testRandom.o -L../../../lib/Random -lRandom libtool: link: mingw32-g++ -g -Wall -pedantic -DNOMINMAX -D_REENTRANT -DWIN32 -I /usr/local/include/w32api -o .libs/testRandom.exe testRandom.o -L/usr/local/lib/w32api -L/home/Tam/src/3DS_Games/lib/Random -lRandom D:\cygwin\opt\MinGW\bin\..\lib\gcc\mingw32\3.4.5\..\..\..\..\mingw32\bin\ld.exe: cannot find -lRandom To link this from the command line using the mingw linker the -L path needs the drive letter i.e mingw32-ld testRandom.o -LD:/home/Tam/src/3DS_Games/lib/Random -lRandom works. The -L path is generated from the makefile.am's which have LDADD = -L$(top_builddir)/lib/Random -lRandom However I can't find how to set top_builddir to a relative path or to start it with the drive letter (my autoconf skills are weak). As a tempoary "solution" I have removed the use of libtool. I could hack a $(DRIVE_LETTER) infront of every -L option, but I'd like to find something better.

• Eclipse plugin installation/update issues

  - by The Elite Gentleman

  I've installed the following Team repository plugins (along with it's dependencies) for Eclipse Helios (using Eclipse updater). MercurialEclipse 1.7.1 Subclipse 1.6.17 Subversive SVN All of these are the latest in Eclipse Marketplace. My problem is when I go to Eclipse "Preferences", under "Team" I only see CVS but under Eclipse Marketplace, I can see that these plugins are installed (it gives me an option to uninstall it). How do I configure my Team repositories to reflect under "Team" in Preferences? Also, there is an update for "Eclipse IDE for Java EE developers, but when I try to update it, the following error occurs: Cannot complete the install because of a conflicting dependency.

• Is there anything like Unity for simple things that don't require an interface?

  - by Dave

  Perhaps I'm misapplying Unity, but here goes. I have a couple of applications, both of which load the same plugin assemblies. All assemblies require a library, and I want them to be able to access this library via Unity. However, in order to use Unity, or any other IoC framework, I'd have to write an interface for this library. I will probably do this, but since an interface isn't really needed for anything other than to support Unity, I am afraid that this means that I am 1) missing the point, or 2) misapplying the framework. If I avoid something that offers me DI, then I'd have to make the library class a singleton, and then pass it to all of the plugin constructors, or via a public property, and I don't want to do this. That said, and without actually implementing anything with Unity yet, I'm not getting one other detail -- although Unity will let me request the library via Resolve<, my plugins will still need to have a reference to the Unity instance that is created in the main applications. So is this a case where your only option is to pass the Unity reference to all of the plugins, but then it's convenient from that point on, merely because you can use Unity to get at all of the other dependencies?

• How do I keep child elements together with parent jQuery sortable.

  - by unknowndomain

  I have a list of items like this... <ol> <li> <span></span> <img src="image.png" /> <p>Image Caption</p> </li> </ol> And I want to be able to sort the LI's but not the sub elements, they should just move with their parent. I am using the jQuery to do that... $('ol li').sortable({ 'cursor': 'move' }); And its working but not moving the whole lot just the element you clicked i.e. the <p>, <img> or <span> I can't figure out how to solve this so I looked about and found an option called 'items': '> li' which was recommended but upon using this nothing drags any more but using firebug + jquery plugin I can see there is a sortable on the <li> still. Not sure what to do, example here: http://clareshilland.unknowndomain.co.uk/ Press ctrl+l to login. Enter the login details: Username: clarePassword: demo Select 'edit' from under then 'image' portion of the menu. The sortables should be those polaroids. Thanks in advance, another one I've been banging my head on the table with.

• php get, random records, and the back button

  - by Andrew Heath

  My site has a library full of games, nations, game scenarios, etc. library.php is given a type=___ & id=___ for example library.php?type=scenario&id=ABCD001 library.php saves the id to a session variable and loads an include appropriate for the type This all works just dandy. Now, I wanted to give my users the option of pulling up a random scenario. To do that, I added a special id to the logic within lib-scenario.php (the include) such that if given library.php?type=scenario&id=random the include knows to run an alternate query for a random record rather than for the actual id This also works just dandy... unless someone hits the Random Scenario button two+ times in a row, and decides that the previous random scenario was way cooler, I want to go back to that. Because the http address is always directory/library.php?type=scenario&id=random no matter how many times you click Random Scenario, as soon as you click back you'll be taken to the last page with an alternate address you visited. So, if you start at the Home page, and hit Random Scenario 35 times, then decide the 34th one was what you wanted and click BACK, you'll be put back onto the Home page. I must admit this was not a problem I had anticipated. One of my testers was the first to have the urge to back-up in the random scenario stream and here we are. How can I add back-up functionality to my script?

• wcf 4.0 service on IIS7

  - by Jan

  I am currently developing a service with wcf 4.0 (visual studio 2010 RC). When I try my service on the Visual Studio Development Server, it all works perfect. However, when I tree to run my service on IIS7 on a windows 7 machine, the service doesn't work anymore. (I already changed the framework version on my application pool). When I call an operation on the service, like the default operation GetData when I create a service, I get an error. I used the WCF test client to connect to the service. When I call the operation on the service, the Visual Studio Just-In-Time debugger shows the following message: An unhandled win32 exception occured in w3wp.exe The Just-In-Time debugger was launched without necessary security permissions. To debug this proces, the JIT debugger must be run as an administrator. Would you like to debug the proces? As far as I know, I am running Visual Studio as an administrator and this is probably the process that starts the JIT debugger. The only option I have is to debug the W3WP process, which is probably not the right thing to do. What can I do the make the Service to run on IIS7?

• LocalAlloc and LocalRealloc usage

  - by PaulH

  I have a Visual Studio 2008 C++ Windows Mobile 6 application where I'm using a FindFirst() / FindNext() style API to get a collection of items. I do not know how many items will be in the list ahead of time. So, I would like to dynamically allocate an array for these items. Normally, I would use a std::vector<>, but, for other reasons, that's not an option for this application. So, I'm using LocalAlloc() and LocalReAlloc(). What I'm not clear on is if this memory should be marked fixed or moveable. The application runs fine either way. I'm just wondering what's 'correct'. int count = 0; INFO_STRUCT* info = ( INFO_STRUCT* )LocalAlloc( LHND, sizeof( INFO_STRUCT ) ); while( S_OK == GetInfo( &info[ count ] ) { ++count; info = ( INFO_STRUCT* )LocalRealloc( info, sizeof( INFO_STRUCT ) * ( count + 1 ), LHND ); } if( count > 0 ) { // use the data in some interesting way... } LocalFree( info ); Thanks, PaulH

• Determining whether geographic point is within X meters of a state border (using shapefile for borde

  - by DanM

  So I'm writing a Java app, and I've got an ESRI Shapefile which contains the borders of all the U.S. states. What I need is to be able to determine whether any given lat/lon point is within a specified distance from ANY state border line - i.e., I will not be specifying a particular border line, just need to see whether the point is close to any of them. The solution does NOT have to be very precise at all; e.g. I don't need to be dealing with measuring perpendicular to the border, or whatever. Just checking to see if going X meters north, south, east or west would result in crossing a border would be more than sufficient. The solution DOES have to be computationally efficient, as I'll be performing a huge number of these calculations. I'm planning to use the GeoTools library (though if there's a simpler option, I'm all for it) with the Shapefile plugin. What I don't really understand is: Once I've got the shapefile loaded into memory, how do I check to see whether I'm near a border? Thanks! -Dan

• Flex (Lex, not actionscript or w/e) Error

  - by incrediman

  I'm totally new to flex. I'm getting a build error when using flex. That is, I've generated a .c file using flex, and, when running it, am getting this error: 1>lextest.obj : error LNK2001: unresolved external symbol "int __cdecl isatty(int)" (?isatty@@YAHH@Z) 1>C:\...\lextest.exe : fatal error LNK1120: 1 unresolved externals here is the lex file I'm using (grabbed from here): /*** Definition section ***/ %{ /* C code to be copied verbatim */ #include <stdio.h> %} /* This tells flex to read only one input file */ %option noyywrap %% /*** Rules section ***/ /* [0-9]+ matches a string of one or more digits */ [0-9]+ { /* yytext is a string containing the matched text. */ printf("Saw an integer: %s\n", yytext); } . { /* Ignore all other characters. */ } %% /*** C Code section ***/ int main(void) { /* Call the lexer, then quit. */ yylex(); return 0; } As well, why do I have to put a 'main' function in the lex syntax code? What I'd like is to be able to call yylex(); from another c file.

• Q on Python serialization/deserialization

  - by neil

  What chances do I have to instantiate, keep and serialize/deserialize to/from binary data Python classes reflecting this pattern (adopted from RFC 2246 [TLS]): enum { apple, orange } VariantTag; struct { uint16 number; opaque string<0..10>; /* variable length */ } V1; struct { uint32 number; opaque string[10]; /* fixed length */ } V2; struct { select (VariantTag) { /* value of selector is implicit */ case apple: V1; /* VariantBody, tag = apple */ case orange: V2; /* VariantBody, tag = orange */ } variant_body; /* optional label on variant */ } VariantRecord; Basically I would have to define a (variant) class VariantRecord, which varies depending on the value of VariantTag. That's not that difficult. The challenge is to find a most generic way to build a class, which serializes/deserializes to and from a byte stream... Pickle, Google protocol buffer, marshal is all not an option. I made little success with having an explicit "def serialize" in my class, but I'm not very happy with it, because it's not generic enough. I hope I could express the problem. My current solution in case VariantTag = apple would look like this, but I don't like it too much import binascii import struct class VariantRecord(object): def __init__(self, number, opaque): self.number = number self.opaque = opaque def serialize(self): out = struct.pack('>HB%ds' % len(self.opaque), self.number, len(self.opaque), self.opaque) return out v = VariantRecord(10, 'Hello') print binascii.hexlify(v.serialize()) >> 000a0548656c6c6f Regards

• Fancybox close button not showing when using different template

  - by VeraG

  I have a page where I need to use 2 different FancyBox styles for different elements on the page. To achieve that, I added tpl option and modified stylesheet accordingly. Here is what I have: $(document).ready(function() { $(".login").fancybox({ closeClick : false, closeBtn : true, tpl: { wrap : '<div class="fancybox-wrap1" tabIndex="-1"><div class="fancybox-skin1"><div class="fancybox-outer"><div class="fancybox-inner"></div></div></div></div>', closeBtn : '<a title="Close" class="fancybox-item fancybox-close" href="javascript:;"></a>' } }); }); In my CSS, I added new styles for .fancybox-wrap1 and .fancybox-skin1. Styles work great BUT on the FancyBox with modified template "close" button completly disappears! I tried both adding and deleting closeBtn from tpl but it doesn't seem to make any difference. I also have a demo here (eventually I will need different background-images for FancyBox, not just background-color, that's why I'm doing it). What am I doing wrong? Any help will be greatly appreciated!

• "Decompile" Javascript function? *ADVANCED*

  - by caesar2k

  [1] Ok, I don't even know how to call this, to be honest. So let me get some semi-pseudo code, to show what I'm trying to do. I'm using jquery to get an already existing script declared inside the page, inside a createDocument() element, from an AJAX call. GM_xmlhttprequest({ ... load:function(r){ var doc = document_from_string(r.responseText); script_content = $('body script:regex(html, local_xw_sig)', doc).html(); var scriptEl = document.createElement('script'); scriptEl.type = 'text/javascript'; scriptEl.innerHTML = script_content; // good till here (function(sc){ eval(sc.innerHTML); // not exactly like this, but you get the idea, errors alert('wont get here ' + local_xw_sig); // local_xw_sig is a global "var" inside the source })(scriptEl); } }); so far so good, the script indeed contains the source from the entire script block. Now, inside this "script_content", there are auto executing functions, like $(document).ready(function(){...}) that, everything I "eval" the innerHTML, it executes this code, halting my encapsulated script. like variables that doesn't exist, etc removing certain parts of the script using regex isn't really an option... what I really wanted is to "walk" inside the function. like do a (completely fictional): script = eval("function(){" + script_content + "};"); alert(script['local_xw_sig']); // a03ucc34095cw3495 is there any way to 'disassemble' the function, and be able to reach the "var"s inside of it? like this function: function hello(){ var message = "hello"; } alert(hello.message); // message = var inside the function is it possible at all? or I will have to hack my way using regex? ;P [2] also, is there any way I can access javascript inside a document created with "createDocument"?

• parameter for xcodebuild for using latest sdk.

  - by Maciek Sawicki

  I using ant exec task to execute xcodebuild to build some iOS projects hudson. I would like to be able to crate script that way that allows not to specify sdk version, because after updating sdk on hudson slave or my iOS projects all my projects failing.... There is is nice option in xcode since sdk 4.2 in target setup Base SDK - Latest iOS and I don't have to provide -sdk param in xcodebuild command, but then (i think) it's taken from xcode project and it's bad because then some one can change target from simulator to device accidentally during commit. I need something that is constant. I will prefer not to use env variable because I would like to be able to run this ant task also on dev machines and would like not have to renember about setting it on all machines. Unfortunately xcodebuild -showsdk gives only: Mac OS X SDKs: Mac OS X 10.4 -sdk macosx10.4 Mac OS X 10.5 -sdk macosx10.5 Mac OS X 10.6 -sdk macosx10.6 iOS SDKs: iOS 4.2 -sdk iphoneos4.2 iOS Simulator SDKs: Simulator - iOS 3.2 -sdk iphonesimulator3.2 Simulator - iOS 4.0 -sdk iphonesimulator4.0 Simulator - iOS 4.1 -sdk iphonesimulator4.1 Simulator - iOS 4.2 -sdk iphonesimulator4.2 I need something like -sdk iphoneosLatest. My only idea is to pare output of xcodebuild -showsdk with some script, but I don't like this idea.
