• How should a one-man development shop document their code?

  - by CKoenig

  Hi, please let me first describe my situation. I work in an IT department for a small-to-medium sized industrial-company and basically I'm the only real developer (sometimes a second guy joins in for his own projects). I programm mostly in C#/.net. Of course I only programm for internal need (Intranet, reporting, data-driven apps, some mobile apps, ...). My question is how should I document my work? It's a highly dynamic environment (the features and bug fixes I implement are tested by me during production, and go live, often within a day. If I technical documentation like MSDN or even overview diagramms those would take me more time to sync than the whole programming process. Also I feel it's a waste of time because I would be the only one who ever read it. I do understand that if I get sick, leave, or forget this documentation would be valuable. PS:well of course you are right - the quesion is how much and how/where. I try using the XML-docu comments for the public exposed parts but as I'm a believer in self-documenting code the comments mostly restates in plain text what you can read from the method-head itself :(Maybe using the remarks section is the key but if you have 30 lines of code with a 15 line xml-comment in front it just looks dirty (sorry for posting it here but our firewall rejects JSON :( )

• How do I start up an NSRunLoop, and ensure that it has an NSAutoreleasePool that gets emptied?

  - by Nick Forge

  I have a "sync" task that relies on several "sub-tasks", which include asynchronous network operations, but which all require access to a single NSManagedObjectContext. Due to the threading requirements of NSManagedObjectContexts, I need every one of these sub-tasks to execute on the same thread. Due to the amount of processing being done in some of these tasks, I need them to be on a background thread. At the moment, I'm launching a new thread by doing this in my singleton SyncEngine object's -init method: [self performSelectorInBackground:@selector(initializeSyncThread) withObject:nil]; The -initializeSyncThread method looks like this: - (void)initializeSyncThread { self.syncThread = [NSThread currentThread]; self.managedObjectContext = [(MyAppDelegate *)[UIApplication sharedApplication].delegate createManagedObjectContext]; NSRunLoop *runLoop = [NSRunLoop currentRunLoop]; [runLoop run]; } Is this the correct way to start up the NSRunLoop for this thread? Is there a better way to do it? The run loop only needs to handle 'performSelector' sources, and it (and its thread) should be around for the lifetime of the process. When it comes to setting up an NSAutoreleasePool, should I do this by using Run Loop Observers to create the autorelease pool and drain it after every run-through?

• svn dev cycle. howto lots minor "features" pending for approval.

  - by Julian Davchev

  Hi I've read similar questions regarding that but still feel the need to ask a question. I have scenario where we have lots of tiny "features" pending for approval. I generally see two approaches. 1.Keep trunk solid and have tons of branches for each tiny "feature". Basically every new thingy is a branch. Cons: - Might become nightmare to support so many branches no matter how small a change. Keeping all branches in sync etc etc. - Worst con I see in this is setup of test system so one can easily examine changes to approve (basically need to support all branches which seems insane). Pros: - Seemningly easy once approved a branch to be merged back to trunk and new release to be tagged and deployed. 2.For big features a branch is released and for small changes all goes in trunk(relatively stable) directly. Pros: - Easier to set test system as most of the time all will be directly visible. For big features should be easy to maintain separate branch on test. Cons: - Don't really see how release will go. I will not be able to basically release one part of trunk This would involve cherrypicking which is crazy to follow. Other approach is I just enforce that after some time (a week or so) all small features need to be approved so they can deployed before giving new tasks. I just create release branch and either all or none of small features are going live. This will be some fun discussion with head people. I guess having lots of small pending stuff is very problematic to follow technically.

• Powershell 2.0 Hang When Run From MsDeploy pre- post- ops using c/

  - by SonOfNun

  I am trying to invoke powershell during the preSync call in a MSDeploy command, but powershell does not exit the process after it has been called. The command (from command line): "tools/MSDeploy/msdeploy.exe" -verb:sync -preSync:runCommand="powershell.exe -NoLogo -NoProfile -NonInteractive -ExecutionPolicy Unrestricted -Command C:/MyInstallPath/deploy.ps1 Set-WebAppOffline Uninstall-Service ",waitInterval=60000 -usechecksum -source:dirPath="build/for-deployment" -dest:wmsvc=BLUEPRINT-X86,username=deployer,password=deployer,dirPath=C:/MyInstallPath I used a hack here (http://therightstuff.de/2010/02/06/How-We-Practice-Continuous-Integration-And-Deployment-With-MSDeploy.aspx) that gets the powershell process and kills it but that didn't work. I also tried taskkill and the sysinternals equivalent, but nothing will kill the process so that MSDeploy errors out. The command is executed, but then just sits there. Any ideas what might be causing powershell to hang like this? I have found a few other similar issues around the web but no answers. Environment is Win 2K3, using Powershell 2.0. UPDATE: Here is a .vbs script I use to invoke my powershell command now. Invoke using 'cscript.exe path/to/script.vbs': Option Explicit Dim oShell, appCmd,oShellExec Set oShell = CreateObject("WScript.Shell") appCmd = "powershell.exe -NoLogo -NoProfile -NonInteractive -ExecutionPolicy Unrestricted -Command ""&{ . c:/development/materialstesting/deploy/web/deploy.ps1; Set-WebAppOffline }"" " Set oShellExec = oShell.Exec(appCmd) oShellExec.StdIn.Close()

• how to do these in visio 2007?

  - by user285825

  I am very annoyed with this software. I am unable to do many things with this software. In the book 'UML distilled' many features of UML are discussed which I am not sure how to accomplish with visio 2007. For instance, 1) I can't find the unary association. In the UML static structure under shapes panel on left, there are a lot of components like package, class, blah, blah, binary association, blah, blah, association class. But where is unary association. 2) For sequence diagram, I created a message (any of sync, async, call type message, ordinary message). The I tried to incorporate some parameter information. I went to the properties. There were a category called arguments. But selecting that shows a table where arguments are supposed to be shown. But all are diasbled. 3) For sequence diagram, there is no component delete (the big X) in the UML Sequence. 4) For class diagram, there is supposed to be a comment compartment where comments like mentioning the responsibilities are allowed using a comment prefixed with "--". But I am not sure how to accomplish them. 5) there is also supposed to be a way to indicate static properties of a class. But I am not sure how to do that in visio. 6) there is supposed to be a stereotype for class <. But in the stereotype drop down there is no stereotype. 7) where is the ball and socket component?

• servlet resopnse data for autocomplete

  Hello experts, Following code is in php. i want to do same in java. Please tell me how do i generate this type of array or collection in java.

• Copy SQL Server data from one server to another on a schedule

  - by rwmnau

  I have a pair of SQL Servers at different webhosts, and I'm looking for a way to periodically update the one server using the other. Here's what I'm looking for: As automated as possible - ideally, without any involvement on my part once it's set up. Pushes a number of databases, in their entirely (including any schema changes) from one server to the other Freely allows changes on the source server without breaking my process. For this reason, I don't want to use replication, as I'd have to break it every time there's an update on the source, and then recreate the publication and subscription One database is about 4GB in size and contains binary data. I'm not sure if there's a way to export this to a script, but it would be a mammoth file if I did. Originally, I was thinking of writing something that takes a scheduled full backup of each database, FTPs the backups from one server to the other once they're done, and then the new server picks it up and restores it. The only downside I can see to this is that there's no way to know that the backups are done before starting to transfer them - can these backups be done synchronously? Also, the server being refreshes is our test server, so if there's some downtime involved in moving the data, that's fine. Does anybody out there have a better idea, or is what I'm currently considering the best non-replication way to go? Thanks for your help, everybody. UPDATE: I ended up designing a custom solution to get this done using BAT files, 7Zip,command line FTP, and OSQL, so it runs in a completely automatic way and aggregates the data from a dozen servers across the country. I've detailed the steps in a blog entry. Thanks for all your input!

• Trimming bit of the beginning off a recorder waveform

  - by Lowgain

  I've got a flash 10.1 app that lets me record microphone input to a wav without a media server, which I am saving to an Amazon S3 bucket. I have another process running on a server which gets wavs from this bucket, converts to mp3 using LAME and puts them into another bucket. This all works fine, but in converting wav mp3, about 0.1sec or so of silence is added to my sound. In the application this are being used in, perfect sync is critical, so I need to trim off that little bit. If I have to trim it off the original waveform that is okay, I don't expect anything important to happen in that first fraction of a second. What is the best way to go about this? I am using Adobe's WavWriter to convert by ByteArray into a proper waveform. Is there a way I can easily trim off the first few samples from my ByteArray without invalidating the structure? Alternatively, is there a good server-side tool I can use to trim the wav before running it through LAME, or an argument I can give LAME? Or, could I even trim that sound off the mp3 after it has been converted? Thanks!

• Passing an ActionScript JPG Byte Array to Javscript (and eventually to PHP)

  - by Gus

  Our web application has a feature which uses Flash (AS3) to take photos using the user's web cam, then passes the resulting byte array to PHP where it is reconstructed and saved on the server. However, we need to be able to take this web application offline, and we have chosen Gears to do so. The user takes the app offline, performs his tasks, then when he's reconnected to the server, we "sync" the data back with our central database. We don't have PHP to interact with Flash anymore, but we still need to allow users to take and save photos. We don't know how to save a JPG that Flash creates in a local database. Our hope was that we could save the byte array, a serialized string, or somehow actually persist the object itself, then pass it back to either PHP or Flash (and then PHP) to recreate the JPG. We have tried: - passing the byte array to Javascript instead of PHP, but javascript doesn't seem to be able to do anything with it (the object seems to be stripped of its methods) - stringifying the byte array in Flash, and then passing it to Javascript, but we always get the same string: ÿØÿà Now we are thinking of serializing the string in Flash, passing it to Javascript, then on the return route, passing that string back to Flash which will then pass it to PHP to be reconstructed as a JPG. (whew). Since no one on our team has extensive Flash background, we're a bit lost. Is serialization the way to go? Is there a more realistic way to do this? Does anyone have any experience with this sort of thing? Perhaps we can build a javascript class that is the same as the byte array class in AS?

• ASP.NET "Object reference not set..." error

  - by Roman

  Hi, I have a website written using ASP.NET. We have a development machine and a deployment server. The site works great on the development machine, but when is transfered (using simple FTP Upload) generates strange behavior. It starts working just fine, but after a while stops working and throws an exception "Exception: Object reference not set to an instance of an object.". The deal is that the absolute path of the website on the development machine is different than on the deployment server (and why should they be similar?) and the exact error is: Exception: Object reference not set to an instance of an object. at SOMEPROJECT_Objects.Player..ctor(Int32 PlayerID) in C:\inetpub\wwwroot\SOMEPROJECTSolution\ALLPROJECT\SOMEPROJECT_Objects\Player.cs:line 123 at SOMEPROJECT_GameLayer.M_Game.PlayerActiveGame(Int32 PlayerID) in C:\inetpub\wwwroot\SOMEPROJECTSolution\ALLPROJECT\SOMEPROJECT_GameLayer\M_Game.cs:line 85 at Web.getsms.Page_Load(Object sender, EventArgs e) in C:\inetpub\wwwroot\SOMEPROJECTSolution\ALLPROJECT\SOMEPROJECT-sms\Web\getsms.aspx.cs:line 59 The address that it is looking for is the address on the DEVELOPMENT machine, where as the site now resides on the deployment server. Any ideas why this happens would be appreciated. Thanks, Roman

• svnsync loses revision properties although hook installed

  - by roesslerj

  Hello all! I have a pretty weird problem. We have setup an SVN-Mirror via cronjob (because it needs to go from inside to outside of a firewall, so no post-commit-hook possible) and svnsync. We installed a pre-revprop-hook just as told. Everything seems to work fine, except that it doesn't. E.g. when manually executing the script. # svnsync --non-interactive sync file://<path-to-mirror> --source-username <usr> --source-password <pwd> Committed revision 19817. Copied properties for revision 19817. No error, no complaints. But if checking for the revision properties it says: # svnlook info <path-to-mirror> 0 # svn info -r HEAD file://<path-to-mirror> 2>&1 Path: <root-of-mirror> URL: file://<path-to-mirror> Repository Root: file://<path-to-mirror> Repository UUID: <uid> Revision: 19817 Node Kind: directory Last Changed Rev: 19817 So somehow the author and timestamp information gets lost. But we need that information for our internal processes. Since no error or warning is produced I have absolutely no idea even where to start to look. Everything is local (except for the remote master), so there are no server-logs to look at. I also tried to manually recopy via svnsync copy-revprops (http://chestofbooks.com/computers/revision-control/subversion-svn/svnsync-Copy-revprops-Ref-svnsync-C-Copy-revprops.html). It says Copied properties for revision 19885. But when I query them, it's just the same. Any ideas how I could approach that problem, or even better -- how to solve it? Any ideas appreciated.

• Create a strongly typed view which inherites a class which is concrete

  - by Ashwani K

  Hello All: I am having one class called BaseClass which contains some logic applicable to whole web site. In order to create a strongly typed view we need to inherit the page from System.Web.Mvc.ViewPage generic class. But In our case I have to Inherit the BaseClass from System.Web.Mvc.ViewPage to apply some common settings, but the BaseClass should be inherited from System.Web.Mvc.ViewPage< generic version. But I cannot inherit the BaseClass from System.Web.Mvc.ViewPage< as it will change other class also. So I created one more class of type BaseClass< inheriting it from System.Web.Mvc.ViewPage< and copied the whole code of BaseClass in BaseClass<. But the code in BaseClass is controlled by other team so it will be changed frequently so my BaseClass< should be in sync with BaseClass. Please help me in eliminating the code duplication or any other approach to make strongly typed View. Thanks Ashwani

• Problem running python/matplotlib in background after ending ssh session.

  - by Jamie

  Hi there, I have to VPN and then ssh from home to my work server and want to run a python script in the background, then log out of the ssh session. My script makes several histogram plots using matplotlib, and as long as I keep the connection open everything is fine, but if I log out I keep getting an error message in the log file I created for the script. File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 2058, in loglog ax = gca() File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 582, in gca ax = gcf().gca(**kwargs) File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 276, in gcf return figure() File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 254, in figure **kwargs) File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/backends/backend_tkagg.py", line 90, in new_figure_manager window = Tk.Tk() File "/Home/eud/jmcohen/.local/lib/python2.5/lib-tk/Tkinter.py", line 1647, in __init__ self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use) _tkinter.TclError: couldn't connect to display "localhost:10.0" I'm assuming that it doesn't know where to create the figures I want since I close my X11 ssh session. If I'm logged in while the script is running I don't see any figures popping up (although that's because I don't have the show() command in my script), and I thought that python uses tkinter to display figures. The way that I'm creating the figures is, loglog() hist(list,x) ylabel('y') xlabel('x') savefig('%s_hist.ps' %source.name) close() The script requires some initial input, so the way I'm running it in the background is python scriptToRun.py << start>& logfile.log& Is there a way around this, or do I just have to stay ssh'd into my machine? Thanks.

• Team Build Reports as "Failed" Even Though All Targets Succeeded

  - by benjy

  Hi, I've written a custom MSBuild script to be used with Team Build, as I am storing PHP in TFS and of course it isn't compiled. My custom script calls the CoreGet target to get the latest version of the files, and the copies them, ZIPs, them, and FTPs the ZIP archive to a testing server. All of that is working fine. The problem I am having is that despite the build succeeding - see the output in BuildLog.txt - Done executing task "BuildStep". Done building target "FTP" in project "TFSBuild.proj". Done executing task "CallTarget". Done building target "EndToEndIteration" in project "TFSBuild.proj". Done Building Project "C:\Documents and Settings\tfsservice\Local Settings\Temp\Code\PHP\BuildType\TFSBuild.proj" (EndToEndIteration target(s)). Build succeeded. 0 Warning(s) 0 Error(s) the build still reports as having failed. The log from Visual Studio looks like so: Anyone know how I can make it report as having succeeded? Thanks very much in advance, Benjy P.S.: Please let me know if anyone would find having the whole build script helpful. Thanks!

• How can I test a CRON job with PHP?

  - by alex

  This is the first time I've ever used a CRON. I'm using it to parse external data that is automatically FTP'd to a subdirectory on our site. I have created a controller and model which handles the data. I can access the URL fine in my browser and it works (however I will be restricting this soon). My problem is, how can I test if it's working? I've added this to my controller for a quick and dirty log $file = 'test.txt'; $contents = ''; if (file_exists($file)) { $contents = file_get_contents($file); } $contents .= date('m-d-Y') . ' --- ' . PHP_SAPI . "\n\n"; file_put_contents($file, $contents); But so far only got requests logged from myself from the browser, despite having my CRON running ever minute. 03-18-2010 --- cgi-fcgi 03-18-2010 --- cgi-fcgi I've set it up using cPanel with the command index.php properties/update/ the 2nd portion is what I use to access the page in my browser. So how can I test this is working properly, and have I stuffed anything up? Note: I'm using Kohana 3. Many thanks

• RPC for java/python with rest support, HTML monitoring and goodies

  - by Ran

  Here's my set of requirements: I'm looking for an RPC framework such as thrift, avro, protobuf (when adding services to it) which supports: Easy and intuitive IDL. No serial numbers, no manual versioning, simple... avro is a good example for this. Works with Java and Python Supports both fast binary prorocol, as well as HTTP based restful style. I'd like to be able to use it for both backend-to-backend communication (java-java or python-java) as well as frontend-to-backend communication (javascript to java). The rest support needs to include &param=value input as get/post requests (configurable per request) and output in three possible formats: json, jsonp, XML. Compact, fast, backward compatible, easy to upgrade etc... Provides some nice monitoring interfaces such as: JMX, web page status reports (e.g. packets in, packets out, error rate etc) Ops friendly... no need to take the whole site down to release new versions Both sync and asyc communication ... other goodies are welcome... Is there something out there? So far I've looked at thrift and avro and they are both nice in some ways, but don't check all my list. Thanks

• questions about using svn

  - by ajsie

  i have set up a svn repository in a remote ubuntu server using webdav (http://ip/svn). but i have some questions: should i create one svn repository for each project folder? so i should use "svnadmin create" 5 times for 5 projects? or should i import them to seperate folders in the svn repository? should i after i have created a svn repo, import one project folder into it with "svn import" and then DELETE my original local folder thus only having it in the svn repo in the remote ubuntu server? is this safe or should i still have a local copy for some reason (cause i wont work in that one)? i use netbeans to check out projects from svn repo, then i edit the files and commit the changes. but how should i do to update the live web server content (in /var/www)? should i in my ubuntu server use "svn checkout" and check it out to /var/www or should i use netbeans to check out to a local folder and then upload the files to /var/www with ftp or webdav (and which one of them should i use)? so i got a svn repo and lets say 4 programmers are working with it, checking out and commiting. how do i check what is happening in the repo, which one made which changes, and all the changes from day 1 to day 213? does netbeans/eclipse letting me see this kind of information or do i download another application for it? i should have one svn user for each programmer in the ubuntu server? is this accomplished by using "htpasswd" 4 times for 4 programmers? how do i couple all these users to same group so that i could modify file access specific for the svn group and all its members?

• Getting auth token for dropbox account from accountmanager in android

  - by user1490880

  I am trying to get auth token for a dropbox account configured in device from account manager. I am using accountManager.getAuthToken(account, "DROPBOX",null,Hello.this, new GetAuthTokenCallback(), null);//account" is dropbox account I am seeing a Allow/Deny page. I click on Allow, but the callback is not getting invoked at all and i dont get the auth token. I got the authtoken for a google account with this(with a different authtokentype). What i am missing. I am not sure about the authTokenType parameter for dropbox. Also are there any other parameter specific for dropbox like the bundle parameter that i am missing. Is this way possible for dropbox? Check below for the function parameters public AccountManagerFuture<Bundle> getAuthToken (Account account, String authTokenType, Bundle options, Activity activity, AccountManagerCallback<Bundle> callback, Handler handler) Link: http://developer.android.com/reference/android/accounts/AccountManager.html UPDATE I assume since we are able to create a dropbox account in android Accounts and Sync(Settings), there must be a dropbox authenticator that has all the functions in AbstractAccountAuthenticator implemented including getAuthToken(). So dropbox should support giving auth token i think. Also dropbox uses oauth1, whereas account manager uses outh 2.0. So is this an issue.Can anyone comment on this?

• Python: two loops at once

  - by Stephan Meijer

  I've got a problem: I am new to Python and I want to do multiple loops. I want to run a WebSocket client (Autobahn) and I want to run a loop which shows the filed which are edited in a specific folder (pyinotify or else Watchdog). Both are running forever, Great. Is there a way to run them at once and send a message via the WebSocket connection while I'm running the FileSystemWatcher, like with callbacks, multithreading, multiprocessing or just separate files? factory = WebSocketClientFactory("ws://localhost:8888/ws", debug=False) factory.protocol = self.webSocket connectWS(factory) reactor.run() If we run this, it will have success. But if we run this: factory = WebSocketClientFactory("ws://localhost:8888/ws", debug=False) factory.protocol = self.webSocket connectWS(factory) reactor.run() # Websocket client running now,running the filewatcher wm = pyinotify.WatchManager() mask = pyinotify.IN_DELETE | pyinotify.IN_CREATE # watched events class EventHandler(pyinotify.ProcessEvent): def process_IN_CREATE(self, event): print "Creating:", event.pathname def process_IN_DELETE(self, event): print "Removing:", event.pathname handler = EventHandler() notifier = pyinotify.Notifier(wm, handler) wdd = wm.add_watch('/tmp', mask, rec=True) notifier.loop() This will create 2 loops, but since we already have a loop, the code after 'reactor.run()' will not run at all.. For your information: this project is going to be a sync client. Thanks a lot!

• Building a CMS in PHP: Development tools

  - by TRiG

  I'm planning to build a CMS in PHP and MySQL, mainly for my own amusement and education. (Though who knows, I may come up with something useful and cool. Anything's possible.) I'll be asking questions about code architecture etc. later. For now, I'm more interested in development tools. So far, all my playing with code has been done on a web server, and I've edited over FTP. I was thinking it might be quicker to use a localhost. Also, that way, I could use version control (which I've never done before). So, A. How do I set up a localhost server with many subdomains on an Ubuntu 9.10 computer. Is XAMPP for Linux the way to go, or should I use a standard Apache distro? (Or another webserver altogether?) For that matter, is it possible to set up more than one webserver on the same computer, and to use them for different localhost subdomains? B. How do I set up a version control thingy covering all the code (which will be on several subdomains of localhost, and in a few shared folders)? I've read Joel Spolsky's HgInt tutorial, and it makes Mercurial look good. And simple, especially if you're working on your own. C. Should I continue to use gEdit to write HTML/CSS/JS/PHP, or is there a better free editor out there for these languages?

My code is : Imports System.Text.RegularExpressions Public Class CustomTextBlock Inherits TextBlock Public Event Klik As EventHandler(Of EventArgs) Public ReadOnly InlineCollectionProperty As DependencyProperty = DependencyProperty.Register("InlineCollection", GetType(String), GetType(CustomTextBlock), New PropertyMetadata(New PropertyChangedCallback(AddressOf CustomTextBlock.InlineChanged))) Private Shared Sub InlineChanged(ByVal sender As DependencyObject, ByVal e As DependencyPropertyChangedEventArgs) DirectCast(sender, CustomTextBlock).Inlines.Clear() Dim kelimeler = Split(e.NewValue, " ") For i = 0 To kelimeler.Length - 1 If Regex.Match(kelimeler(i), "(http|ftp|https):\/\/[\w\-_]+(\.[\w\-_]+)+([\w\-\.,@?^=%&amp;:/~\+#]*[\w\-\@?^=%&amp;/~\+#])?").Success Then Dim x = New Hyperlink(New Run(kelimeler(i))) x.AddHandler(Hyperlink.ClickEvent, New RoutedEventHandler(AddressOf t_Click)) x.ToolTip = kelimeler(i) x.Tag = kelimeler(i) DirectCast(sender, CustomTextBlock).Inlines.Add(x) If Not i = kelimeler.Length Then DirectCast(sender, CustomTextBlock).Inlines.Add(" ") Else DirectCast(sender, CustomTextBlock).Inlines.Add(kelimeler(i)) If Not i = kelimeler.Length Then DirectCast(sender, CustomTextBlock).Inlines.Add(" ") End If ''//Console.WriteLine(kelime(i).ToString.StartsWith("@")) Next kelimeler = Nothing End Sub Public Property InlineCollection As String Get Return DirectCast(GetValue(InlineCollectionProperty), String) End Get Set(ByVal value As String) SetValue(InlineCollectionProperty, value) End Set End Property Private Shared Sub t_Click(ByVal sender As Hyperlink, ByVal e As System.Windows.RoutedEventArgs) e.Handled = True RaiseEvent Klik(sender, EventArgs.Empty) End Sub End Class This code gives error at RaiseEvent Klik(sender, EventArgs.Empty) Error is : Cannot refer to an instance member of a class from within a shared method or shared member initializer without an expliticit instance of the class. Thanks for your answers, Alper

• Windows Azure - access webrole local storage from separate workerrole

  - by Brett Smith

  I'm running an application on windows azure, the MVC views need to be dynamic, I started by storing them as records in the database, but am quite keen to move them to a physical location. My concept was to create the physical file via code... which worked great and speeds up the page load dramatically. This was of course before I realised that the files were only available for the duration of the role Next I looked at a start up task to create the files when the role was started - however I then realised that any separate instances weren't going to sync up unless I monitored the database for changes. So I moved from a start up task to a function in the run method of the role that checks the database every 10 minutes to see if changes have occurred. The problem is that this seems to choke up the application (at least in the warm up stage). Ideally I would like to move the run function to it's own worker role that can sit there and push files out to web role instances, but I'm unsure on how I would go about accessing the web roles local storage from the worker role. Can anybody tell me whether this is actually possible? and hopefully point me in the right direction to achieve this? Just to clarify what I'm trying to achieve -View is created in user interface running on web role and stored in database -Separate web role (front end) has clientside application with virtualpath provider pointing Views requests to local storage (localresource) -separate worker role to create View structure and load this into clientside web role local storage

• Different EF Property DataType than Storage Layer Possible?

  - by dj_kyron

  Hi, I am putting together a WCF Data Service for PatientEntities using Entity Framework. My solution needs to address these requirements: Property DateOfBirth of entity Patient is stored in SQL Server as string. It would be ideal if the entity class did not also use the "string" type but rather a DateTime type. (I would expect this to be possible since we're abstracting away from the storage layer). Where could a conversion mechanism be put in place that would convert to and from DateTime/string so that the entity and SQL Server are in sync?. I cannot change the storage layer's structure, so I have to work around it. WCF Data Services (Read-only, so no need for saving changes) need to be used since clients will be able to use LINQ expressions to consume the service. They can generate results based on any given query scenario they need and not be constrained by a single method such as GetPatient(int ID). I've tried to use DTOs, but run into problem of mapping the ObjectContext to a DTO, I don't think that is theoretically possible...or too complicated if it is. I've tried to use Self Tracking Entities but they require the metadata from the .edmx file if I'm correct, and this isn't allowing a different property data type. I also want to add customizations to my Entity getter methods so that a property "MRN" of type "string" needs to have .Replace("MR~", string.Empty) performed before it is returned. I can add this to the getter methods but the problem with that is Entity Framework will overwrite that next time it refreshes the entity classes. Is there a permanent place I can put these? Should I use POCO instead? How would that work with WCF Data Services? Where would the service grab the metadata?

• svnsync looses revision properties although hook installed

  - by roesslerj

  Hello all! I have a pretty weird problem. We have setup an SVN-Mirror via cronjob (because it needs to go from inside to outside of a firewall, so no post-commit-hook possible) and svnsync. We installed a pre-revprop-hook just as told. Everything seems to work fine, except that it doesn't. E.g. when manually executing the script. # svnsync --non-interactive sync file://<path-to-mirror> --source-username <usr> --source-password <pwd> Committed revision 19817. Copied properties for revision 19817. No error, no complaints. But if checking for the revision properties it says: # svnlook info <path-to-mirror> 0 # svn info -r HEAD file://<path-to-mirror> 2>&1 Path: <root-of-mirror> URL: file://<path-to-mirror> Repository Root: file://<path-to-mirror> Repository UUID: <uid> Revision: 19817 Node Kind: directory Last Changed Rev: 19817 So somehow the author and timestamp information gets lost. But we need that information for our internal processes. Since no error or warning is produced I have absolutely no idea even where to start to look. Everything is local (except for the remote master), so there are no server-logs to look at. Any ideas how I could approach that problem, or even better -- how to solve it? Any ideas appreciated.
