• embed dll in html <object>

  - by Raynos

  I've come across some old code <object id="foo" classid="/location/bar.dll#ProjectName.ClassName" viewastext></object> It doesn't currently work and used to work in older versions of IE. I've never come across embedding a dll in a web page like this. It appears to be a windows .NET application written in C#. This is used on our intranet. And ClassName is of type System.Windows.Forms.UserControl It also seems I can call the C# methods of the UserControl directly through javascript. Does anyone have any documentation on how this works and whether its possible to hack it into firefox. Rewriting the windows control as a web application would be a nightmare. [Edit] It appears to be some kind of activeX / COM thing where in IE you could just port a windows application directly into a html file. It's supposed to be able to run locally if you set up various correctly. If anyone has an idea of what needs to be set up for this to work, that would be nice.

• NSIS patching (multiple patches in one file)

  - by Owen

  I'm able to generate patch files from one version to another using NSIS' Vpatch. Let's say I have mydll.dll version 1, and I have a patch to update it to version 2. Then I have a new version again, thus I generate another patch to update it to version 3. What bothers me though is, what if user cancels updating to version 2 and so forth. Then my latest version let's say is version 20. User decides to update to version 20. Is there a way to generate a patch that's like accumulative in nature? whereas user can jump from version any old version to the newest version (i.e ver 3 to ver 20) without passing through the versions in between? I've read this line in vpatch's documentation --- "if you want to be able to upgrade version 1 and 2 to version 3, you can put a 1 3 and 2 3 patch in one file." But how do I that? What if I alread have like 30 versions. Does that mean I have to create a patch whose arguments are old files(versions 1-29) and new file(version20)? Any help would be appreciated. Thanks...

• jQuery $.getJSON - How do I parse a flickr.photos.search REST API call?

  - by Chad

  Trying to adapt the $.getJSON Flickr example: $.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?", function(data){ $.each(data.items, function(i,item){ $("<img/>").attr("src", item.media.m).appendTo("#images"); if ( i == 3 ) return false; }); }); to read from the flickr.photos.search REST API method, but the JSON response is different for this call. Click here to see the JSON response. This is what I've done so far: var url = "http://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=9322c53dde3b36bda33f79c16bb99104&tags=yokota+air+base&safe_search=1&per_page=20"; var src; $.getJSON(url + "&format=json&jsoncallback=?", function(data){ $.each(data.photos, function(i,item){ src = "http://farm"+ item.photo.farm +".static.flickr.com/"+ item.photo.server +"/"+ item.photo.id +"_"+ item.photo.secret +"_m.jpg"; $("<img/>").attr("src", src).appendTo("#images"); if ( i == 3 ) return false; }); }); I guess I'm not building the image src correctly. Couldn't find any documentation on how to build the image src, based on what the JSON response is. How do you parse a flickr.photos.search REST API call?

• Adding a block of XML as child of a SimpleXMLElement object

  - by miCRoSCoPiC_eaRthLinG

  Hey all, I have this SimpleXMLElement object with a XML setup similar to the following... $xml <<< EOX <books> <book> <name>ABCD</name> </book> </books> EOX; $sx = new SimpleXMLElement( $xml ); Now I have a class named Book that contains info. about each book. The same class can also spit out the book info. in XML format akin the the above (the nested block).. example, $book = new Book( 'EFGH' ); $book->genXML(); ... will generate <book> <name>EFGH</name> </book> Now I'm trying to figure out a way by which I can use this generated XML block and append as a child of so that now it looks like... for example.. // Non-existent member method. For illustration purposes only. $sx->addXMLChild( $book->genXML() ); ...XML tree now looks like: <books> <book> <name>ABCD</name> </book> <book> <name>EFGH</name> </book> </books> From what documentation I have read on SimpleXMLElement, addChild() won't get this done for you as it doesn't support XML data as tag value. Any ideas on how I should go about this ? Thanks, m^e

• Mac OS X Status Bar Application - Hiding it from Cmd/Alt menu?

  - by Moddy

  I'm trying to whip up a simple little Status Bar Application in Obj-C/Cocoa. So I have done it pragmatically - declaring an NSStatusItem, adding it to the NSStatusBar and then giving it a NSMenu object. A bit like this... NSStatusBar *bar = [NSStatusBar systemStatusBar]; theItem = [bar statusItemWithLength:NSVariableStatusItemLength]; [theItem retain]; [theItem setTitle: NSLocalizedString(@"Tablet",@"")]; [theItem setHighlightMode:YES]; [theItem setMenu:theMenu]; (Example taken from "Status Bar Programming Topics", Apple Documentation) Now ideally, I'd like this application to run and not be accessible from the CMD/ALT window changing "menu" (for lack of a better word), I've seen applications do it before and would like that really. The idea is I just want it to be accessible from every window, whilst not having its own NSMenu on the status bar, and whilst not being able to have it as the active application ( - so its not able to take over the whole Status Bar, and its not able to be seen through CMD/ALT) Additionally, I was wondering if the StatusBarItem supports the ability to drag-n-drop an item onto it? I'm not sure if thats a limitation of the NSStatusBar though. I've read up on deamons and agents, but that seems far too low level/over kill for such a simplistic app! Cheers in advance!

• Enumerating computers in NT4 domain using WNetEnumResourceW (C++) or DirectoryEntry (C#)

  - by Kevin Davis

  I'm trying to enumerate computers in NT4 domains (not Active Directory) and support Unicode NetBIOS names. According to MSDN, WNetEnumResourceW is the Unicode counterpart of WNetEnumResource which to me would imply that using this would do the trick. However, I have not been able to get Unicode NetBIOS names properly using WNetEnumResourceW. I've also tried the C# rough equivalent DirectoryEntry using the WinNT: provider with no luck on Unicode names either. If I use DirectoryEntry on Active Directory (using the LDAP: provider) I do get Unicode names back. I noticed that during some debugging my code using DirectoryEntry and the WinNT: provider, the exceptions I saw were of type System.Runtime.InteropServices.COMException which tends to make me believe that this is just calling WNetEnumResourceW via COM. This web page implies that for some Net APIs the MS documentation is incomplete and possibly inaccurate which further confuses things. Additionally I've found that using the C# method which certainly results in cleaner, more understandable code also yields incomplete results in enumerating computers in domains\workgroups. Does anyone have any insight on this? Is it possible that computer acting as the WINS server is mangling the name? How would I determine this? Thanks

• On Render Callback For G+ Button

  - by Michael Robinson

  How might I go about performing an action only when a G+ button has finished rendering? Facebook allows one to do this using the following: FB.XFBML.parse(document, function() { alert('rendering done'); }); I've perused Google's documentation, but didn't see anything helpful. Currently my workaround is to monitor the G+ element until certain elements have been added, then perform my action: (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; po.onload = function() { var awaitRender = function(element) { if (element.firstChild && element.firstChild.firstChild && element.firstChild.firstChild.tagName.toUpperCase() === 'IFRAME') { alert('rendered!'); } else { window.setTimeout(function() { awaitRender(element) }, 100); } }; var buttons = document.getElementsByClassName('googleplus-button'); for(var i = 0; i < buttons.length; i++) { awaitRender(buttons[i]); } } var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })(); I'd like to know please, if there is either: A correct way one should do this for G+ buttons A better implementation that what I've hacked together above

• KeyStore, HttpClient, and HTTPS: Can someone explain this code to me?

  - by stormin986

  I'm trying to understand what's going on in this code. KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType()); FileInputStream instream = new FileInputStream(new File("my.keystore")); try { trustStore.load(instream, "nopassword".toCharArray()); } finally { instream.close(); } SSLSocketFactory socketFactory = new SSLSocketFactory(trustStore); Scheme sch = new Scheme("https", socketFactory, 443); httpclient.getConnectionManager().getSchemeRegistry().register(sch); My Questions: trustStore.load(instream, "nopassword".toCharArray()); is doing what exactly? From reading the documentation load() will load KeyStore data from an input stream (which is just an empty file we just created), using some arbitrary "nopassword". Why not just load it with null as the InputStream parameter and an empty string as the password field? And then what is happening when this empty KeyStore is being passed to the SSLSocketFactory constructor? What's the result of such an operation? Or -- is this simply an example where in a real application you would have to actually put a reference to an existing keystore file / password?

• Concept of WNDCLASSEX, good programming habits and WndProc for system classes

  - by luiscubal

  I understand that the Windows API uses "classes", relying to the WNDCLASS/WNDCLASSEX structures. I have successfully gone through windows API Hello World applications and understand that this class is used by our own windows, but also by Windows core controls, such as "EDIT", "BUTTON", etc. I also understand that it is somehow related to WndProc(it allows me to define a function for it) Although I can find documentation about this class, I can't find anything explaining the concept. So far, the only thing I found about it was this: A Window Class has NOTHING to do with C++ classes. Which really doesn't help(it tells me what it isn't but doesn't tellme what it is). In fact, this only confuses me more, since I'd be tempted to associate WNDCLASSEX to C++ classes and think that "WNDCLASSEX" represents a control type . So, my first question is What is it? In second place, I understand that one can define a WndProc in a class. However, a window can also get messages from the child controls(or windows, or whatever they are called in the Windows API). How can this be? Finally, when is it a good programming practise to define a new class? Per application(for the main frame), per frame, one per control I define(if I create my own progress bar class, for example)? I know Java/Swing, C#/Windows.Form, C/GTK+ and C++/wxWidgets, so I'll probably understand comparisons with these toolkits.

• Implement a custom editor in Visual Studio 2008 or 2010

  - by David Montgomery

  Hi, I'm trying to find documentation on how one would go about creating a custom editor plug-in for VS2008 or VS2010. The file syntax I want to edit is from a tool called TemplateMaschine by Stefan Sarstedt. An example of the template syntax: <%@ Assembly Name="System.Xml" %> <%@ Import NameSpace="System.Xml" %> <%@ Import NameSpace="System.Collections" %> <%@ Argument Name="className" Type="string" %> <%@ Argument Name="attributes" Type="ArrayList" %> public class <%=className%> { <% foreach(string attr in attributes) { %> public string <%=attr%>; <% } %> } The most important editor features for me would be real-time syntax checking and code completion. If we could get those features, it would save us THOUSANDS of man-hours. Failing to incorporate a custom editor into Studio, maybe there is some open source text editor project out there that might be easy to extend for my purposes? I've looked a little at Eclipse, but I would think code completion won't be an option (also, my Java stinks). Another possibility might be extending the SharpDevelop text editor component. Ideas and suggestions welcome!

• Can't draw UImage in UIView::drawRect

  - by Joel

  I know this seems like a simple task, which is why I don't understand why I can't get the image to render. When I set up my UIView, I do the following: myUiView.backgroundColor = [UIColor clearColor]; myUiView.opaque = NO; I create and retain the UIImage in the init function of my UIView: image = [[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"test" ofType:@"png"]] retain]; then my drawRect looks like this: - (void) drawRect:(CGRect) rect { [image drawInRect:self.bounds]; } Ultimately I'll be manipulating that UIImage via bitmap context, and then in drawRect create a CGImage out of the context, and render that, but for now I'm just trying to get it rendering a known image. I've been digging through this site, as well as the documentation. I've gone down the CG path and tried drawing it with CGContextDrawImage by following the numerous examples other people have posted, but that didn't work either. So I've come back to what seems to be the most straightforward way to draw an image, but it isn't working. Any help would be greatly appreciated. Thanks in advance.

• SQL Server 2008 spatial index and CPU utilization with MapGuide Open Source 2.1

  - by Antonio de la Peña

  I have a SQL Server table with hundreds of thousands of geometry type parcels. I have made indexes on them trying different combinations of density and objects per cell settings. So far I'm settiling for LOW, LOW, MEDIUM, MEDIUM and 16 objects per cell and I made a SP that sets the bounding box according to the extents of the entities in the table. There is an incredible performance boost from queries taking almost minutes without index to less than seconds, it gets faster when the zoom is closer thus less objects are displayed. Yet the CPU utilization gets to 100% when querying for features, even when the queries themselves are fast. I'm worrying this will not fly in a production environment. I am using MapGuide Open Source 2.1 for this project, but I am positive the CPU load is caused by SQL Server. I wonder if my indexes are set properly. I haven't found any clear documentation on how to properly set them up. Every article I've read basically says "it depends..." but nothing specific. Do you have any recommendations for me, including books, articles? Thank you.

• Creating a Function in SQL Server with a Phone Number as a parameter and returns a Random Number

  - by Emer

  Hi Guys, I am hoping someone can help me here as google is not being as forthcoming as I would have liked. I am relatively new to SQL Server and so this is the first function I have set myself to do. The outline of the function is that it has a Phone number varchar(15) as a parameter, it checks that this number is a proper number, i.e. it is 8 digits long and contains only numbers. The main character I am trying to avoid is '+'. Good Number = 12345678 Bad Number = +12345678. Once the number is checked I would like to produce a random number for each phone number that is passed in. I have looked at substrings, the like operator, Rand(), left(), Right() in order to search through the number and then produce a random number. I understand that Rand() will produce the same random number unless alterations are done to it but right now it is about actually getting some working code. Any hints on this would be great or even point me towards some more documentation. I have read books online and they haven't helped me, maybe I am not looking in the right places. Here is a snippet of code I was working on the Rand declare @Phone Varchar (15) declare @Counter Varchar (1) declare @NewNumber Varchar(15) set @Phone = '12345678' set @Counter = len(@Phone) while @Counter > 0 begin select case when @Phone like '%[0-9]%' then cast(rand()*100000000 as int) else 'Bad Number' end set @counter = @counter - 1 end return Thanks for the help in advance Emer

• Delphi Pascal / Windows API - Small problem with SetFilePointerEx and parameter FILE_END

  - by SuicideClutchX2

  I know I am about to be slapped by at least one person who was helping me with this API. Alright I have been able to use SetFilePointerEx just fine, when setting the position only. SetFilePointerEx(PD,512,@PositionVar,FILE_BEGIN); SetFilePointerEx(PD,0,@PositionVar,FILE_CURRENT); Both work, I can set positions and even check my current one. But when I set FILE_END as per the documentation no matter what the second parameter is and whether or not i provide a pointer for the third parameter it fails even on a valid handle that many other operations are able to use without fail. For Example: SetFailed := SetFilePointerEx(PD,0,@PositionVar,FILE_END); SetFailed := SetFilePointerEx(PD,0,nil,FILE_END); Whatever I put it fails. I am working with a handle to a physical disk and it most definitely has an end. SetFilePointer works just fine its just a little more trouble than I would like. Its not the end of the world, but whats happening.

• Free solution for automatic updates with .NET/C#?

  - by a2h

  Yes, from searching I can see this has been asked time and time again. Here's a backstory. I'm an individual hobbyist developer with zero budget. A program I've been developing has been in need of constant bugfixes, and me and users are getting tired of having to manually update. Me, because my current solution of Manually FTP to my website Update a file "newest.txt" with the newest version Update index.html with a link to the newest version Hope for people to see the "there's an update" message Have them manually download the update sucks, and whenever I screw up an update, I get pitchforks. Users, because, well, "Are you ever going to implement auto-update?" "Will there ever be an auto-update feature?" Over the past few hours I have looked into: http://windowsclient.net/articles/appupdater.aspx - I can't comprehend the documentation http://www.codeproject.com/KB/vb/Auto_Update_Revisited.aspx - Doesn't appear to support anything other than working with files that aren't in use http://wyday.com/wyupdate/ - wyBuild isn't free, and the file specification is simply too complex. Maybe if I was under a company paying me I could spend the time, but then I may as well pay for wyBuild. http://www.kineticjump.com/update/default.aspx - Ditto. ClickOnce - Workarounds for implementing launching on startup are massive, horrendous and not worth it for such a simple feature. Publishing is a pain; manual FTP and replace of all files is required for servers without FrontPage Extensions. I'm pretty much ready to throw in the towel right now and strangle myself. And then I think about Sparkle...

• OS X: Terminal output of javac is garbled.

  - by Don Werve

  I've got my computer set up in Japanese (hey, it's good language practice), and everything is all fine and dandy... except javac. It displays localized error messages out to the console, but they're in Shift-JIS, not UTF8: $ javac this-file-doesnt-exist.java javac: ?t?@?C??????????????: this-file-doesnt-exist.java ?g????: javac <options> <source files> ?g?p?\??I?v?V?????~??X?g?????A-help ???g?p???? If I pipe the output through nkf -w, it's readable, but that's not really much of a solution: $ javac this-file-doesnt-exist.java 2>&1 | nkf -w javac: ????????????: this-file-doesnt-exist.java ???: javac <options> <source files> ????????????????????-help ?????? Everything else works fine (with UTF8) from the command-line; I can type filenames in Japanese, tab-completion works fine, vi can edit UTF-8 files, etc. Although java itself spits out all its messages in English (which is fine). Here's the relevant bits of my environment: LC_CTYPE=UTF-8 LANG=ja_JP.UTF-8 From what it looks like, javac isn't picking up the encoding properly, and java isn't picking up the language at all. I've tried -Dfile.encoding=utf8 as well, but that does nada, and documentation on the localization of the JVM toolchain is pretty nonexistent, at least from Google.

• Multiple inequality conditions (range queries) in NoSQL

  - by pableu

  Hi, I have an application where I'd like to use a NoSQL database, but I still want to do range queries over two different properties, for example select all entries between times T1 and T2 where the noiselevel is smaller than X. On the other hand, I would like to use a NoSQL/Key-Value store because my data is very sparse and diverse, and I do not want to create new tables for every new datatype that I might come across. I know that you cannot use multiple inequality filters for the Google Datastore (source). I also know that this feature is coming (according to this). I know that this is also not possible in CouchDB (source). I think I also more or less understand why this is the case. Now, this makes me wonder.. Is that the case with all NoSQL databases? Can other NoSQL systems make range queries over two different properties? How about, for example, Mongo DB? I've looked in the Documentation, but the only thing I've found was the following snippet in their docu: Note that any of the operators on this page can be combined in the same query document. For example, to find all document where j is not equal to 3 and k is greater than 10, you'd query like so: db.things.find({j: {$ne: 3}, k: {$gt: 10} }); So they use greater-than and not-equal on two different properties. They don't say anything about two inequalities ;-) Any input and enlightenment is welcome :-)

• How to restrict a content of string to less than 4MB and save that string in DB using C#

• Sms via a nokia phone over a serial port

  - by abigblackman

  Hi, I'm trying to send a sms via a Nokia phone over serial which is easy enough via putty. The commands from the nokia documentation works fine. However, trying to send the same commands from a c# application fails miserably. I've run Sysinternals PortMon and can see the commands come through OK, the only difference I can see is in the way it connects but I am having trouble finding the commands that would iron out those differences. The code I'm running looks a little bit like this using (SerialPort port = new SerialPort(comPort, 9600, Parity.None, 8, StopBits.One)) { port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); port.ErrorReceived += new SerialErrorReceivedEventHandler(port_ErrorReceived); //port.ReceivedBytesThreshold = 1; port.DtrEnable = true; port.RtsEnable = true; port.ReadTimeout = 1; port.Handshake = Handshake.XOnXOff; try { port.Open(); port.WriteLine("AT"); port.WriteLine("AT+CMGF=1"); port.WriteLine("AT+CMGS=\"" + number + "\""); port.WriteLine(message); port.Write(new byte[] { (byte)26 }, 0, 1); } finally { if (port.IsOpen) { port.Close(); } } The differences I'm seeing in the trace from the serial port are At the start 0.00001844 aspnet_wp.exe IOCTL_SERIAL_SET_HANDFLOW USBSER001 SUCCESS Shake:1 Replace:43 XonLimit:4096 XoffLimit:4096 And at the very end 0.00061153 aspnet_wp.exe IOCTL_SERIAL_PURGE USBSER001 SUCCESS Purge: RXABORT RXCLEAR 0.00004442 aspnet_wp.exe IOCTL_SERIAL_PURGE USBSER001 SUCCESS Purge: TXABORT TXCLEAR Has anyone got any tips on how to iron out these issues? I also notice that the phone is not responding back to the application with any acknowledgement when I issue a command so I suspect the problem is with the connection, not those messages at the end.

• KODO: how set up fetch plan for bidirectional relationships?

  - by BestPractices

  Running KODO 4.2 and having an issue inefficient queries being generated by KODO. This happens when fetching an object that contains a collection where that collection has a bidrectional relationship back to the first object. Class Classroom { List<Student> _students; } Class Student { Classroom _classroom; } If we create a fetch plan to get a list of Classrooms and their corresponding Students by setting up the following fetch plan: fetchPlan.addField(Classroom.class,”_students”); This will result in two queries (get the classrooms and then get all students that are in those classrooms), which is what we would expect. However, if we include the reference back to the classroom in our fetch plan in order for the _classroom field to get populated by doing fetchPlan.addField(Student.class, “_classroom”), this will result in X number of additional queries where X is the number of students in each classroom. Can anyone explain how to fix this? KODO already has the original Classroom objects at the point that it's executing the queries to retrieve the Classroom objects and set them in each Student object's _classroom field. So I would expect KODO to simply set those objects in the _classroom field on each Student object accordingly and not go back to the database. Once again, the documentation is sorely lacking with Kodo/JDO/OpenJPA but from what I've read it should be able to do this more efficiently. Note-- EAGER_FETCH.PARALLEL is turned on and I have tried this with caching (query and data caches) turned on and off and there is no difference in the resultant queries.

• Code Coverage tool for BlackBerry

  - by Skrud

  I'm looking for a code coverage tool that I can use with a BlackBerry application. I'm using J2ME-Unit for Unit Testing and I want to see how much of my code is being covered by my tests. I've tried using Cobertura for J2ME but after days of wrestling with it I failed to get any results from it. (I believe that the instrumentation is un-done by the RAPC compilation). And despite this message, the project seems to be dead. I've looked at JInjector but the project seems very incomplete. There is little (if any) documentation and although it claims to be able to work with BlackBerry projects, I haven't seen any places where it has been used for that purpose. I've played with the project quite a bit but to no avail. I've also tried the "Coverage" view in the BlackBerry JDE, even though I use Eclipse for development. The view stays permanently blank, regardless of clicking "Refresh" and running the application from the JDE. I've looked at most of the tools on this SO thread, but they won't work with J2ME/BlackBerry projects. Has anyone had any success with any code coverage tools on the BlackBerry? If so, what tools have you used? How have you used them? If anyone has managed to get JInjector or Cobertura for J2ME to work with a BlackBerry project, what did you have to do to get it working?

• Is this a hole in dynamic binding in C# 4?

  - by Galilyou

  I've seen a very interesting post on Fabio Maulo's blog. Here's the code and the bug if you don't want to jump to the url. I defined a new generic class like so: public class TableStorageInitializer<TTableEntity> where TTableEntity : class, new() { public void Initialize() { InitializeInstance(new TTableEntity()); } public void InitializeInstance(dynamic entity) { entity.PartitionKey = Guid.NewGuid().ToString(); entity.RowKey = Guid.NewGuid().ToString(); } } Note that InitializeInstance accepts one parameter, which is of type dynamic. Now to test this class, I defined another class that is nested inside my main Program class like so: class Program { static void Main(string[] args) { TableStorageInitializer<MyClass> x = new TableStorageInitializer<MyClass>(); x.Initialize(); } private class MyClass { public string PartitionKey { get; set; } public string RowKey { get; set; } public DateTime Timestamp { get; set; } } } Note: the inner class "MyClass" is declared private. Now if i run this code I get a "Microsoft.CSharp.RuntimeBinder.RuntimeBinderException" on the line "entity.PartitionKey = Guide.NewGuid().ToString()". The interesting part, though is that the message of the exception says "Object doesn't contain a definition for PartitionKey". Also note that if you changed the modifier of the nested class to public, the code will execute with no problems. So what do you guys think is really happening under the hood? Please refer to any documentation -of course if this is documented anywhere- that you may find?

• Boost Property_Tree iterators, how to handle them?

  - by Andry

  Hello... I am sorry but I asked a question about the same argument before, but my problem concerns another aspect of the one described in that question (How to iterate a boost...). My problem is this, take a look at the following code: #include <iostream> #include <string> #include <boost/property_tree/ptree.hpp> #include <boost/property_tree/xml_parser.hpp> #include <boost/algorithm/string/trim.hpp> int main(int argc, char** argv) { using boost::property_tree::ptree; ptree pt; read_xml("try.xml", pt); ptree::const_iterator end = pt.end(); for (ptree::const_iterator it = pt.begin(); it != end; it++) std::cout << "Here " << it->? << std::endl; } Well, as told me in the previous question, there is the possibility to use iterators on property_tree in Boost, but I do not know what type it is... and what methods or properties I can use... Well, I assume that it must be another ptree or something representing another xml hierarchy to be browsed again (if I want) but documentation about this is very bad... I do not know why, but in boost docs I cannot find nothing good about this... just something about a macro to browse nodes, but this approach is one I would really like to avoid... Well, the question is so... Once getting the iterator on a ptree, how can I access node name, value, parameters (a node in a xml file)? Thankyou

• DotNetNuke and Subversion guidelines

  - by David Stratton

  I've Googled, Binged, and here at StackOverflow, looked through the related questions and searched, but I'm not finding what I'm looking for. I've also searched documentation on DNN. What I'm looking for is any guidance (tutorials, blogs, step-by-step instructions for setting up a repository) etc from people who are experienced in using DotNetNuke with SVN. We use SVN for all our source control, and have no problem with standard applications, because we pretty much built the repository and directory structure to work with our processes. This means when we do web sites, in Visual Studio, we do file based web sites, rather than setting them up in the local IIS. It just makes things easier for us. However, with DNN, it appears that even if you get the source code, it is expecting to be set up in the local IIS, which means additional headaches for us. For example, we are moving all of our source code off our local C drives, and onto a shared drive on a server. This is to enable backups in addition to our normal source control. (This was a management decision). So that means that we need to change the virtual web app when we make the move. Has anyone come up with a good way to work around this? Can DNN be set up so that the developer web server in Visual Studio can be used, so that we can treat it just like any normal web app? Am I missing something obvious? Edit - added I'm willing to accept answers like "We tried it and never got it to work", and "It can't be done" as answers. I'm always open to hearing "It can't be done the way you want. You need to change your procedures to match how it works" if necessary. I guess if you've got experience trying this and just couldn't get it to work, I can learn from your experience that way as well, but some detail would be good.
