• Documenting preprocessor defines in Doxygen

  - by Fire Lancer

  Is it possible to document preprocessor defines in Doxygen? I expected to be able to do it just like a variable or function, however the Doxygen output appears to have "lost" the documentation for the define, and does not contain the define its self either. I tried the following /**My Preprocessor Macro.*/ #define TEST_DEFINE(x) (x*x) and /**@def TEST_DEFINE My Preprocessor Macro. */ #define TEST_DEFINE(x) (x*x) I also tried putting them within a group (tried defgroup, addtogroup and ingroup) rather than just at the "file scope" however that had no effect either (although other items in the group were documented as intended). I looked through the various Doxygen options, but couldn't see anything that would enable (or prevent) the documentation of defines.

• Learning Python coming from PHP

  - by Coronatus

  Community wiki so don't vote to close, kthxbai. My dynamic language experience is solely PHP. I want to learn Python now to broaden my career opportunities and just because I like programming. :) When learning Java, I used a site (lost the URL/real name now), something like "Java for PHP developers" that had all on one side of the page the PHP code, and on the other side the Java code to do the same thing. Is there a website like that for Python? Any other recommendations/advice? Thanks Edit: I have no votes left today, but I'll up-vote good answers tomorrow :)

• SSRS default renderer strips html tags

  - by stackoverflowuser

  For TFS task work item, I copy a table from ms word 2003/2007 document and paste it into the description field (supports rich text). When the task item is saved, correct formatting is saved in TFS database table. But when the same data is displayed in a SSRs report (through report manager) the formatting is lost. Probably the ssrs rendering engine is stripping off the tags. I have the "HTML-Interpret HTML tags as styles" enabled for the report field. It will be of great help if someone can provide more information on this issue and how it can be handled. Thanks.

• where do i put html files in my web-app folder for a lift project with maven?

  - by egervari

  I'm new to Lift framework for scala. For some reason, index.html resides in the web-app directory, and when I start up jetty, http://localhost:8080/ will point to that index.html file just fine. However, if I put a login.html file in the same folder as the index.html, and then go http://localhost:8080/login, Lift does not serve the file. Where do I need to put the files to get them register? I am a little lost because the behaviour only seems to work for index.html and nothing else. This is what happens when I view source in Chrome: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <body>The Requested URL /login was not found on this server</body> </html>

• MediaElement seems to disable lock screen when playing a video

  - by CrossProduct

  I am working on an application that plays a video using the MediaElement component. Now, I would like that if the user is idle, the lock screen appears, as configured by the user in the Settings of the device. If I don't play a video, the lock screen indeed appears. But, when a video is playing no lock screen appears. I cannot find any information on this. Currently I set the idle detection modes like this: PhoneApplicationService.Current.ApplicationIdleDetectionMode = IdleDetectionMode.Enabled; PhoneApplicationService.Current.UserIdleDetectionMode = IdleDetectionMode.Enabled; I am a bit lost now. The only solution I can think of is running a timer myself and stop the video playback after a certain time. (but there seems to be no API calls to receive the configured lock timeout.) Any suggestions are welcome, thanks.

• Launching an activity at its current state.

  - by Profete162

  Hello, I am trying to make a task switcher and i succed in it. My only problem is that when I launch activities, they are relaunched as they were new activities ( for instance, I am writing an email, i press home and go into my activity,launch email, and then the app launch the email bout goes back at the inbox and the email is lost) So that's not true multitasking. Here are my steps: 1) getting all the running apps: List<ActivityManager.RunningTaskInfo> allTasks = activityManager.getRunningTasks(30); 2) getting the intent: for (ActivityManager.RunningTaskInfo aTask : allTasks) { Intent i = new Intent(Intent.ACTION_MAIN); i.setComponent(aTask.baseActivity); (...) 3) Launching the application when clicking on the button: intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK| Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED).addCategory(Intent.CATEGORY_LAUNCHER); monthis.startActivity(intent); ` What is wrong with this code? Should I do something different to get it? Thank a lot for any answer.

• How to learn to program C the right way

  - by sfactor

  i have been programming in C/C++ for my academic courses a lot and was under the impression i had a pretty good grasp of it. but lately i had to work in a bluetooth application that had a server and client implementation in a Linux box and an embedded system. i learned bluez bluetooth API, socket/network programming and coded it. however i ran into a lot of problems with memory leaks and segmentation faults and other memory related errors along the way.as the code grew more complex i all but lost control of the pointers and threads and sockets. this got me wondering that i had a lot to learn that they didn't say in the basic C/C++ books. so i wanted to ask for the resources that are available that'll help be code better in a professional way in C/C++ .especially for the Linux/Mac environment (gcc compiler).

• How to skip integers in C++ taken from a fstream txt file?

  - by Elaina

  I need to create a function that uses a loop. This function will open a text file and then must be able to skip a variable number of leading random integers. The program must be able to handle any number of leading random integers. Example if the opened file reads this on its first line: 100 120 92 82 38 49 102 and the SKIP_NUMBER variable is assigned 3 the number the function would grab is 82. The function must continue to grab the integers every SKIP_NUMBER until it reaches the end of the file. These integers taken from the txt file are then placed into another text file. Please help I'm really lost on how to create this loop! :D Here is my function so far... //Function skips variables and returns needed integer int skipVariable (int SKIP_NUMBER) { return 0; //temporary return } These are my program variables: // initialize function/variables ifstream fin; string IN_FILE_NAME, OUT_FILE_NAME; int SKIP_NUMBER;

• Looking for easy way to analyze var_dump (PHP) on large objects

  - by sdek

  I know (PHP's) var_dump is supposed to be "human readable" and all, but analyzing large objects is just a pain in the neck. I am struggling to make sense of a few of the large objects that are being passed around in a script that we are running. (I know that using xdebug with and IDE is a good idea, but I have not been able to get xdebug to run on this project for some reason - several days lost, ugh). Any ideas on how I can easily digest the contents of a really big var_dump? Any ideas are welcome... Although I am hoping that there is something similar to Thomas Frank's JSON tool (where you just put some code in and it gives a nice graphical representation).

• Reversing the effects of mkimage to get an original gzipped file back

  - by Alex Marshall

  Hello, We develop for a specific embedded device at our company, and part of that is making initial root disks that get loaded onto the devices over ethernet via netboot. We've experienced some problems, and as a result, the original folder with the contents of the initial root disks was lost along with its backups, but we do still have the initrd images, that have been created by gzipping the contents of a ramdisk that's been mounted as a local loop device, and then running mkimage on the gzipped file. Is there any way to undo the effects of mkimage and obtain the original gzipped content so that we can recover the original images ?

• facebook php-sdk not logging out

  - by Meisam Mulla

  I'm having a hard time getting this to work. I use the following to generate the logout url: $logout = "https://www.facebook.com/logout.php?next=" . urlencode('http://' . $_SERVER['SERVER_NAME'] . $_SERVER['PHP_SELF']) . "&access_token=" . $facebook->getAccessToken(); Which generates the correct (worked with the last version) url: https://www.facebook.com/logout.php?next=http%3A%2F%2F...&access_token=AA....ZD However this does not actually log the user out. I tried using $facebook->getLogoutUrl(array('next' => 'myurl')) which generates pretty much the same url. This also did not work. I am lost as to why its not logging the user out. I actually tried manually putting the address into the address bar but it redirects me to the Facebook homepage.

• need to query MongoDB using php

  - by Mario Villarroel

  I need to query mongodb with something like this: ("something" < X OR "something" = "nll") AND ("someother"X OR "someother"= "nll") AND z=$z AND s=1 I've tried a few things, but can't get it to work, this is what I've tried: find( array( '$or'=array(array("something"=array("$le",$X)),array("something"="nll")), '$or'=array(array("someother"=array("$ge",$X)),array("someother"="nll")) )) But that's getting me the OR overwritten, so I'm lost on that... After diggin a bit more, I assembled this code that seems to be what I need, but doesn't work either: find( array('$and'=array( array( '$or' = array( array("something"=array('$gte'=$X)),array("something"="nll"))), array('$or' = array( array("someother"=array('$lte'=$X)),array("someother"="nll")))),"Z"=$z, "s"="1"); But this doesn't work as it returns zero results and I know for sure that there are more than 2 items that match on the db. (100% certain)

• How do I measure the time elapsed when calling a WCF Webservice?

  - by Manuel R.

  We want to track the time taken by a web service call between a client and the server. This time should not include the time taken by the server to process the request. The idea is that we want to see how much time of a web service call is lost due to the actual transfer trough the network. Does WCF already offer something in this direction? Of course I could just add a timer on the client and subtract the server processing time but that wouldn't be very elegant.

• NHibernate very slow during debugging

  - by HeavyWave

  Have anyone stumbled upon a problem where NHibernate is extremely slow in Visual Studio while debugging, but behaves normally when run separately? Logging is disabled and the time lost seems to be when the actual queries are executed, NHProfiler shows that queries were executed very quickly (on SQL side I presume), but each session with 10 queries takes about 4 seconds. I am using SQL Express Server. As I said, even if I turn on full logging and run my application without Visual Studio it is a magnitude faster. Update. After hours and hours of work towards the issue I was able to fix it by simply switching project type from Windows Application to Console Application (although in reality it's a Windows Service, but it always worked before with Windows Application project type). What could possibly be the difference to bring NHibernate to a halt in debugging mode?

• vim - how am I suppose to read this command to remove all blanks at the end of a line

  - by whaley

  I happened across this page full of super useful and rather cryptic vim tips at http://rayninfo.co.uk/vimtips.html. I've tried a few of these and I understand what is happening enough to be able to parse it correctly in my head so that I can possibly recreate it later. One I'm having a hard time getting my head wrapped around though are the following two commands to remove all spaces from the end of every line :%s= *$== : delete end of line blanks :%s= \+$== : Same thing I'm interpreting %s as string replacement on every line in the file, but after that I am getting lost in what looks like some gnarly variation of :s and regex. I'm used to seeing and using :s/regex/replacement. But the above is super confusing. What do those above commands mean in english, step by step?

• php/mysql show data from chosen checkboxes

  - by Michael

  Hi. I have a table called FRUIT id type daysold 1 banana 5 2 apple 6 3 apple 4 4 peach 2 5 banana 6 What I would like is to have 3 checkboxes: Banana [ ] Apple [ ] Peach [ ] SUBMIT Then if I've only checked "Banana" and "Peach" the mysql output should only show me the rows that matches those two types. And the checkboxes should remain checked to highlight what was chosen. I can make the checkboxes but then that's about it really. I don't know how to properly get the info from the checkboxes and down to the WHERE argument in the MYSQL-code. Especially not with two types chosen. If it was just a dropdown menu with a single choice then I'd add the choice to the url and put WHERE type='$choice' - but I'm struggling with the multiple choices. I'm a bit of a novice at both php and mysql, so I'm a bit lost on this one.

• GridView styling (CSS classes) disappears

  - by ProfK

  I'm migrating a large number of stand-alone pages into content pages. Most of this involves little more than copying and pasting a GridView from one page into the new page. However, I find that styling disappears in the new project, i.e. the styles (as classes) are still present in the stylesheet, but these classes are no longer applied to GridView table elements. Example, in the old project, once a table is rendered by the GridView, its header row has a class of HeaderStyle, but in the new project this is lost, without any editing of the GridView. Is there some mysterious, built-in mechanism that automatically applies these attributes to GridView elements that I have somehow disabled?

• ASP.NET MVC Persisting mdoel's ID value when Editing

  - by user295017

  public Edit(int? id){ /* Codes */ } [HttpPost] public Edit(Item model){ /* Codes */ } I retrieve a copy of Item in the first Edit method, which would contain a value for ItemID. But when it gets to the HttpPost method, the id value's lost. If switched to public Edit(int? ItemID){ /* Codes */ } [HttpPost] public Edit(Item model){ /* Codes */ } this way ItemID can be persisted in the Item model. But is this a good way to handle it? Will ASP.NET MVC always be able to know that it needs to plug "ItemID" into Item? and are there other ways to persist the ID value? Thanks.

• Getting data from a ListView into an array

  - by Joe

  I have a ListView control on my form set up like this in details mode: What I would like to do, is get all the values of the data cells when the user presses the Delete booking button. So using the above example, my array would be filled with this data: values(0) = "asd" values(1) = "BS1" values(2) = "asd" values(3) = "21/04/2010" values(4) = "2" This is my code so far: Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim items As ListView.SelectedListViewItemCollection = _ Me.ManageList.SelectedItems Dim item As ListViewItem Dim values(0 To 4) As String Dim i As Integer = 0 For Each item In items values(i) = item.SubItems(i).Text i = i + 1 Next End Sub But only values(0) gets filled with the first data cell of the selection (in this case "asd") and the rest of the array entries are blank. I have confirmed this with a breakpoint and checked the array entries myself. I'm REALLY lost on this, and have been trying for about an hour now. Any help would be appreciated, thanks :) Also please note that there can only be one row selection at once. Thanks.

• jQuery DOM append losing markup

  - by Raj

  This is related to an earlier question. I try to append HTML DOM returned in an AJAX response to an existing DIV. I see all the text, but it seems all markup such as bold, italic, etc is lost. My AJAX (XML) data is like so: <event source="foo"> <contents> <h1>This is an event</h1> This is the body of the event </contents> </event> My jQuery code does this: $("#eventDiv").append( jData.find("contents").contents().clone() ); Attempting to do .html() on the cloned contents throws an exception: TypeError: Cannot call method 'replace' of undefined. I am a little surprised that it is so excruciatingly hard to do this with jQuery. Am I doing something too far off the track?

• Rails: Settingslogic accessible to users?

  - by neezer

  I have my app configured with Settingslogic, which I love. My question is how to I make a page on my Rails app where Administrators can make changes to the settings specified in config/settings.yml?? I assume said page would have to read and display appropriate form fields for all the values in the YAML file, then save those values back to config/settings.yml? Would those settings take effect immediately or would the server need to be restarted? Bit lost here. Thanks. Related: http://stackoverflow.com/questions/2907643/rails-application-settings

• Subversion: setting up a remote repository and running my site off it?

  - by Matt Andrews

  Hi all. I'm new to SVN and have experimented with it locally on my Dreamhost test server (which has a Subversion "one-click-install" function). Having found my way around the functionality I'm definitely sold, but a little lost about using it to manage my work website (not hosted with Dreamhost, so not offering a one-click SVN installation). Am I correct in thinking that I can set up a repository on my website root (which contains all the files), and then when I develop new features and run a commit, this will update my site? Is this the proper workflow for this sort of thing? If so, is there a standard way to set this kind of thing up on my remote server? Thanks.

• Rails: form input type and getting the filename

  - by Shyam

  Hi, As I am using Ruby on Rails to build an application, which only runs locally, I am lost in the woods (a nuby without a compass). I have a simple MVC application and my view is missing one thing I could really use. I want to select a local file just to retrieve it's filename. I know it's relatively easy to use the form tag helpers for uploading: <%= file_field 'upload', 'datafile' %></p> I wonder how I could get the filename from the selected file, without uploading the file.
