• Find Methods in a c# File programmatically

  - by sajad

  Hi Friends, I want to write a code to search for method defination and methods called in a c# file. So obviously my pattern should search for text like 1.public void xyz(blahtype blahvalue); 2.string construct = SearchData(blahvalue); Has anyone done similar to this, is Regex helpful in this case. if yes provide me the pattern. Any other workarounds. I dont know reflection(will it help in my case) Thanks, you guys gave it a try, i did not know this wud be so complex. All i wanted to do was suppose i have method like this public method1(int val) { method2(); method3(); } void method2(int val2) { method4() } i wanted to construct a string as Method1:Method2:method4 and Method1:Method3.... I guess its really complex

• Best way to simplify this code, more efficient

  - by Derek

  My question is, is there a way to make this code more efficient or write it in a simple way? javascript by the way. switch (tempvar1) { case 1: currentSlide = 'slide1'; showaslide('ppslide1'); break; case 2: currentSlide = 'slide2'; showaslide('ppslide2'); break; case 3: currentSlide = 'slide3'; showaslide('ppslide3'); break; case 4: currentSlide = 'slide4'; showaslide('ppslide4'); break; case 5: currentSlide = 'slide5'; showaslide('ppslide5'); break; case 6: currentSlide = 'slide6'; showaslide('ppslide6'); break; // 20 total cases }

• Twisted - how to create multi protocol process and send the data between the protocols

  - by SpankMe

  Hey, Im trying to write a program that would be listening for data (simple text messages) on some port (say tcp 6666) and then pass them to one or more different protocols - irc, xmpp and so on. I've tried many approaches and digged the Internet, but I cant find easy and working solution for such task. The code I am currently fighting with is here: http://pastebin.com/ri7caXih I would like to know how to from object like: ircf = ircFactory('asdfasdf', '#asdf666') get access to self protocol methods, because this: self.protocol.dupa1(msg) returns error about self not being passed to active protocol object. Or maybe there is other, better, easier and more kosher way to create single reactor with multiple protocols and have actions triggeres when a message arrives on any of them, and then pass that message to other protocols for handling/processing/sending? Any help will be highly appreciated!

• Duplicate partitioning key performance impact

  - by Anshul

  I've read in some posts that having duplicate partitioning key can have a performance impact. I've two tables like: CREATE TABLE "Test1" ( CREATE TABLE "Test2" ( key text, key text, column1 text, name text, value text, age text, PRIMARY KEY (key, column1) ... ) PRIMARY KEY (key, name,age) ) In Test1 column1 will contain column name and value will contain its corresponding value.The main advantage of Test1 is that I can add any number of column/value pairs to it without altering the table by just providing same partitioning key each time. Now my question is how will each of these table schema's impact the read/write performance if I've millions of rows and number of columns can be upto 50 in each row. How will it impact the compaction/repair time if I'm writing duplicate entries frequently?

• Use a push button to add a section in an InfoPath form?

  - by Alex

  I'm working on an InfoPath form that's going to be run with InfoPath Forms Services on a SharePoint server. For a number of reasons -- mostly so that the customer can update the form without involving an administrator -- this can't be a form containing .NET code. The form has a repeating group, and we have users who are a bit confused as to how to add and delete items from the repeating section. I've looked all over the Internets, but haven't been able to find a way to do this without adding a code project to the form. Is there any way to write a rule or do something else to make a button that adds an item to a repeating section?

• How to create a tree with filtered nodes from drupal taxonomy.

  - by sprugman

  I'm trying to create a menu tree in drupal like this: - term 1 node 1 node 2 - sub-term 1 node 3 node 4 + sub-term 2 - sub-term 3 node 5 - sub-sub-term 1 node 6 + term 2 etc. (Sub-term 2 and term 2 are toggled closed.) Some requirements: Output this using something like JQuery Menu to get an interactive tree Filter the nodes by cck type Filter the nodes by cck field Only have terms with nodes or other active terms in them show up Mark the current node as such, and automatically open the tree to that point Do I have to write this myself, or are there a combination of modules that can do it? I've got Advanced Taxonomy Blocks, which is pretty close, but it doesn't list the nodes.

• Get entire text of document as a string using javascript

  - by Tom Dignan

  I am developing a firefox extension and ideally would be able to get the whole darn DOM as a string.. forget any data structure. I just want what I see in "view source" in a buffer. I have been checking out javascript references and HTMLDocument etc. with no avail. Ideally I would be able to write to this buffer as well (seems possible i.e. document.writeLn()) I wish there was a document.read()? Am I just a js noob?

• Cascade the MDI forms of a Splitter panel

  - by BDotA

  I am showing my MDI windows inside the main form but in one part of the splitter panel, like this: Form2 f2= new Form2(); f2.MdiParent = this; f2.Parent = this.splitContainer2.Panel2; f2.Show(); but the problem is that I cannot cascade them if I write a code like this: this.LayoutMdi(System.Windows.Forms.MdiLayout.Cascade); "this" is the parent form. the main form. Hoe can I cascade them? thanks all.

• How can I get JavaDoc into a JunitReport?

  - by benklaasen

  Hi - I'm a tester, with some Java and plenty of bash coding experience. My team is building an automated functional test harness using JUnit 4 and ant. Testers write automated tests in Java and use JavaDoc to document these tests. We're using ant's JunitReport task to generate our test result reports. This works superbly for reporting. What we're missing, however, is a way to combine those JavaDoc free-text descriptions of what the test does along with the JunitReport results. My question is, what's involved to get the JavaDoc into the JunitReport output? I'd like to be able to inject the JavaDoc for a given test method into the JunitReport at the level of each method result. regards Ben

• How to implement arrays in an interpreter?

  - by Ray

  I have managed to write several interpreters including Tokenizing Parsing, including more complicated expressions such as ((x+y)*z)/2 Building bytecode from syntax trees Actual bytecode execution What I didn't manage: Implementation of dictionaries/lists/arrays. I always got stuck with getting multiple values into one variable. My value structure (used for all values passed around, including variables) looks like this, for example: class Value { public: ValueType type; int integerValue; string stringValue; } Works fine with integers and strings, but how could I implement arrays? (From now on with array I mean arrays in my experimental language, not in C++) How can I fit the array concept into the Value class above? Is it possible? How should I make arrays able to be passed around just as you could pass around integers and strings in my language, using the class above? Accessing array elements or memory allocation wouldn't be the problem, I just don't know how to store them.

• How to block the UI during asynchronous operations in WPF

  - by mcintyre321

  We have a WPF app (actually a VSTO WPF app). On certain controls there are multiple elements which, when clicked, load data from a web service and update the UI. Right now, we carry out these web requests synchronously, blocking the UI thread until the response comes back. This prevents the user clicking around the app while the data is loading, potentially putting it into an invalid state to handle the data when it is returned. Of course the app becomes unresponsive if the request takes a long time. Ideally, we'd like to have the cancel button active during this time, but nothing else. Is there a clever way of doing this, or will we have to switch the requests to execute asynchronously using backgroundworker and write something that disables all the controls apart from the cancel button while a request is in progress?

• Delphi> Please explain this: type... procedure of object

  - by Richard Woolf

  I've encountered some code that's new to me... I've never really seen a type declaration of a procedure of object, and I just don't see the point. Why couldn't the developer simply keep a field of type Boolean? interface type TFinishedCaptureEvent = procedure(AFinished: Boolean) of object; TFrameCard = class(TFrame) ... private FOnFinishedCapture: TFinishedCaptureEvent; public property OnFinishedCapture: TFinishedCaptureEvent read FOnFinishedCapture write FOnFinishedCapture; end; implementation ... if Assigned(FOnFinishedCapture) then FOnFinishedCapture(False);

• How to set response header in JAX-RS so that user sees download popup for Excel?

  - by masato-san

  I wrote code that generate Excel file using REST JAX-RS and I confirmed that the generated Excel file is in GlassFish server directory. But my goal is when user click on the button (which generate Excel .xls), I want download popup to show up asking user whether to save or open the .xls file just like any other web services doing for downloading any type of files. According to my search, the step is: generate Excel .xls (DONE) write the excel to stream in JAX-RS file, set response header to something like, String fileName = "Blah_Report.xls"; response.setHeader("Content-Disposition", "attachment; filename=" + fileName); My question is I'm doing all of this in JAX-RS file and I don't have HttpServletResponse object available. According to the answer from Add Response Header to JAX-RS Webservice He says: You can inject a reference to the actual HttpServletResponse via the @Context annotation in your webservice and use addHeader() etc. to add your header. I can't really figure what exactly that means without sample code..

• Custom login in Django

  - by alpgs

  Django newbie here. I wrote simplified login form which takes email and password. It works great if both email and password are supplied, but if either is missing i get KeyError exception. According to django documentation this should never happen: By default, each Field class assumes the value is required, so if you pass an empty value -- either None or the empty string ("") -- then clean() will raise a ValidationError exception I tried to write my own validators for fields (clean_email and clean_password), but it doesn't work (ie I get KeyError exception). What am I doing wrong? class LoginForm(forms.Form): email = forms.EmailField(label=_(u'Your email')) password = forms.CharField(widget=forms.PasswordInput, label=_(u'Password')) def clean_email(self): data = self.cleaned_data['email'] if not data: raise forms.ValidationError(_("Please enter email")) return data def clean_password(self): data = self.cleaned_data['password'] if not data: raise forms.ValidationError(_("Please enter your password")) return data def clean(self): try: username = User.objects.get(email__iexact=self.cleaned_data['email']).username except User.DoesNotExist: raise forms.ValidationError(_("No such email registered")) password = self.cleaned_data['password'] self.user = auth.authenticate(username=username, password=password) if self.user is None or not self.user.is_active: raise forms.ValidationError(_("Email or password is incorrect")) return self.cleaned_data

• Code coordinates to match compass bearings

  - by pinnacler

  Right now in Matlab (0,0) is the origin, 0 degrees / 2pi would be to the right of the cartesian plane and angles are measured counter clockwise with 90 degrees being at the top. I'm trying to write a simulator where the coordinates would match a compass bearing. 0/360 degrees or 2pi would be at the top and 90 degrees would be on the right. Any idea how to code in Matlab or c++? I'd imaging it'd be a matrix flipped about the x axis and rotated 90 degrees but I'm at a total loss. Phil

• Set date format in ruby model (sinatra/datamapper)

  - by Gearóid

  Hi, I have a ruby model that contains a date attribue which I'd like to be able to pass in as a parameter in the format dd/MM/yyyy. However, my sqlite3 db stores the data in yyyy-MM-dd format so when a date like 20/10/2010 gets passed in, it will not be read to the database. I am using the Sinatra framework and using haml for the markup creation. Do I need to write a helper that takes the date string and converts it to the correct format for the db? Or can I set a format type on the models attribute? Thanks.

• What do you do when you feel you need a variatic list comprehension?

  - by cspyr0

  I would like to make a method where I could give it a list of lengths and it would return all combinations of cartesian coordinates up to those lengths. Easier to explain with an example: cart [2,5] Prelude> [ [0,0],[0,1],[0,2],[0,3],[0,4],[1,0],[1,1],[1,2],[1,3],[1,4] ] cart [2,2,2] Prelude> [ [0,0,0],[0,0,1],[0,1,0],[0,1,1],[1,0,0],[1,0,1],[1,1,0],[1,1,1] ] A simple list comprehension won't work because I don't know how long the lists are going to be. While I love Haskell's simplicity for many problems, this is one that I could write procedurally (in C or something) in 5 minutes whereas Haskell gives me an aneurysm! A solution to this specific problem would help me out a lot; I'd also love to hear about your thought processes when tackling stuff like this.

• Joomla Development - Allow Direct File Access AND use Joomla-intern Framework

  - by Email

  Hi As usual you write in Joomla Development defined('_JEXEC') or die('Restricted access'); I make a plugin which needs access from Paypal/IPN, so i exclude that in that specific file. BUT I also need to use the Joomla-intern Variables to access the Database, so i tried this: require("../filewithaccesstoframework.php"); OR even $baseurl = $_SERVER['HTTP_HOST']; $baseurl ="http://".$baseurl."/configuration.php"; require($baseurl); By using the first code it displays "Restircted Access" since it seems to take this from the included file which i can't skip to put-in-there. The second code does not seem to recognize the Variables used in configuration.php like $host, $db, $password. the file configuration.php is chmod 444 Why this happens and is there a workarround to allow direct access to a file AND using the Joomla intern Framework (Variables, Functions)?

• Deleting orphans with JPA

  - by homaxto

  I have a one-to-one relation where I use CascadeType.PERSIST. This has over time build up a huge amount of child records that has not been deleted, to such an extend that it is reflected in the performance. Now I wish to add some code that cleans up the database removing all the child records that are not referenced by a parent. At the moment we are talking 400K+ records, at I need to run the code on all customer installations just to be sure they do not run into the same problem. I think the best solution would be to run a named query (because we support two databases) that deletes the necessary records, and this is where I get into problems, because how should I write it in JPQL? The result I want can be defined like the following sql statement, which unfortunaltely does not run on MySQL. DELETE FROM child c1 WHERE c1.pk NOT IN (SELECT DISTINCT p.pk FROM child c2 JOIN parent p ON p.child = c2.pk);

• Does Displaytag stash the "media type" in a page or request attribute?

  - by Pointy

  When you enable "export" from Displaytag, the tag code gives you links with special magic parameters that the tag recognizes as indicators that the table contents should be exported (as CSV, Excel, whatever). Well I'm interested in detecting the media type so that (for example) I can exclude columns that make no sense in an export (embedded action buttons, for one thing, or checkboxes for row selection). I suppose I could write a table decorator and use that to stick the media type on the request, but it'd be nice to avoid that if the tag already does it. The documentation is not clear on the subject; I guess I can start digging through the source code too.

• Reading Images only from Camera

  - by Ankit

  I wanted to read images only from the Camera folder of the device. Since the folder might be different for different devices, how can I write a simple application for it). So far I have written the following code, which does read from Camera folder, but it also reads from other places on sdcard as well. Cursor childCursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, MediaStore.Images.ImageColumns._ID, null); do { ImageView image = new ImageView(); image.setImageURI(Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, ""+ childCursor.getString( childCursor.getColumnIndex( MediaStore.Images.ImageColumns._ID ))); <some other code> } while (childCursor.moveToNext()); How can I create a generic app and filter on Camera Images before displaying. Any help is appreciated.

• Call the method of base Class which was over ridden

  - by Abhijith Venkata

  I have illustrated my question in this example class Car { public void start(){ System.out.println("Car Started!!!"); } } class Mercedes extends Car { public void start(){ System.out.println("Mercedes Started!!!"); } } Now, in my main program, I write Mercedes m = new Mercedes(); m.start(); It prints: Mercedes Started!!! How do I call the start() method of Car class using the same object so that the output can be Car Started!!!. Edit: Actually It was asked in an interview I attended. I gave the super keyword answer. But the interviewer denied it. He said he'd give me a hint and said Virtual Function. I have no idea how to use that hint.
