  • need some help in Abraham twitteroauth class

    - by diEcho
    Hello All, i m learning how to use twitter from twitter developer link on Authenticating Requests with OAuth page i was debugging my code with given procedure on Sending the user to authorization section there is written that if you are using the callback flow, your oauth_callback should have received back your oauth_token (the same that you sent, your "request token") and a field called the oauth_verifier. You'll need that for the next step. Here's the response I received: oauth_token=8ldIZyxQeVrFZXFOZH5tAwj6vzJYuLQpl0WUEYtWc&oauth_verifier=pDNg57prOHapMbhv25RNf75lVRd6JDsni1AJJIDYoTY my original code is require_once('twitteroauth/twitteroauth.php'); require_once('config.php'); /* Build TwitterOAuth object with client credentials. */ $connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET); /* Get temporary credentials. */ $request_token = $connection->getRequestToken(OAUTH_CALLBACK); /* Save temporary credentials to session. */ $_SESSION['oauth_token'] = $token = $request_token['oauth_token']; $_SESSION['oauth_token_secret'] = $request_token['oauth_token_secret']; /* If last connection failed don't display authorization link. */ switch ($connection->http_code) { case 200: /* Build authorize URL and redirect user to Twitter. */ echo "<br/>Authorize URL:".$url = $connection->getAuthorizeURL($token); //header('Location: ' . $url); break; default: /* Show notification if something went wrong. */ echo 'Could not connect to Twitter. Refresh the page or try again later.'; } and i m getting Authorize URL: https://twitter.com/oauth/authenticate?oauth_token=BHqbrTjsPcyvaAsfDwfU149aAcZjtw45nhLBeG1c i m not getting above URL having oauth_verifier. please tell me from where do i see/debug that url??

  • rails + compass: advantages vs using haml + blueprint directly

    - by egarcia
    I've got some experience using haml (+sass) on rails projects. I recently started using them with blueprintcss - the only thing I did was transform blueprint.css into a sass file, and started coding from there. I even have a rails generator that includes all this by default. It seems that Compass does what I do, and other things. I'm trying to understand what those other things are - but the documentation/tutorials weren't very clear. These are my conclusions: Compass comes with built-in sass mixins that implement common CSS idioms, such as links with icons or horizontal lists. My solution doesn't provide anything like that. (1 point for Compass). Compass has several command-line options: you can create a rails project, but you can also "install" it on an existing rails project. A rails generator could be personalized to do the same thing, I guess. (Tie). Compass has two modes of working with blueprint: "basic" and "semantic" usage. I'm not clear about the differences between those. With my rails generator I only have one mode, but it seems enough. (Tie) Apparently, Compass is prepared to use other frameworks, besides blueprint (e.g. YUI). I could not find much documentation about this, and I'm not interested on it anyway - blueprint is ok for me (Tie). Compass' learning curve seems a bit stiff and the documentation seems sparse. Learning could be a bit difficult. On the other hand, I know the ins and outs of my own system and can use it right away. (1 point for my system). With this analysis, I'm hesitant to give Compass a try. Is my analysis correct? Are Am I missing any key points, or have I evaluated any of these points wrongly?

  • jQuery Ajax / .each callback, next 'each' firing before ajax completed

    - by StuR
    Hi the below Javascript is called when I submit a form. It first splits a bunch of url's from a text area, it then: 1) Adds lines to a table for each url, and in the last column (the 'status' column) it says "Not Started". 2) Again it loops through each url, first off it makes an ajax call to check on the status (status.php) which will return a percentage from 0 - 100. 3) In the same loop it kicks off the actual process via ajax (process.php), when the process has completed (bearing in the mind the continuous status updates), it will then say "Completed" in the status column and exit the auto_refresh. 4) It should then go to the next 'each' and do the same for the next url. function formSubmit(){ var lines = $('#urls').val().split('\n'); $.each(lines, function(key, value) { $('#dlTable tr:last').after('<tr><td>'+value+'</td><td>Not Started</td></tr>'); }); $.each(lines, function(key, value) { var auto_refresh = setInterval( function () { $.ajax({ url: 'status.php', success: function(data) { $('#dlTable').find("tr").eq(key+1).children().last().replaceWith("<td>"+data+"</td>"); } }); }, 1000); $.ajax({ url: 'process.php?id='+value, success: function(msg) { clearInterval(auto_refresh); $('#dlTable').find("tr").eq(key+1).children().last().replaceWith("<td>completed rip</td>"); } }); }); }

  • How do people know so much about programming?

    - by Luciano
    I see people in this forums with a lot of points, so I assume they know about a lot of different programming stuff. When I was young I knew about basic (commodore) and the turbo pascal (pc). Then in college I learnt about C, memory management, x86 set, loop invariants, graphs, db query optimization, oop, functional, lambda calculus, prolog, concurrency, polymorphism, newton method, simplex, backtracking, dynamic programming, heuristics, np completeness, LR, LALR, neural networks, static & dynamic typing, turing, godel, and more in between. Then in industry I started with Java several years ago and learnt about it, and its variety of frameworks, and also design patterns, architecture patterns, web development, server development, mobile development, tdd, bdd, uml, use cases, bug trackers, process management, people management if you are a tech lead, profiling, security concerns, etc. I started to forget what I learnt in college... And then there is the stuff I don't know yet, like python, .net, perl, JVM stuff like groovy or scala.. Of course Google is a must for rapid documentation access to know if a problem has been solved already and how, and to keep informed about new stuff by blogs and places like this one. It's just too much or I just have a bad memory.. how do you guys manage it?

  • Uncatchable AccesViolationException

    - by Roy
    Hi all, I'm getting close to desperate.. I am developing a field service application for Windows Mobile 6.1 using C# and quite some p/Invoking. (I think I'm referencing about 50 native functions) On normal circumstances this goes without any problem, but when i start stressing the GC i'm getting a nasty 0xC0000005 error witch seems uncatchable. In my test i'm rapidly closing and opening a dialog form (the form did make use of native functions, but for testing i commented these out) and after a while the Windows Mobile error reporter comes around to tell me that there was an fatal error in my application. My code uses a try-catch around the Application.Run(masterForm); and hooks into the CurrentDomain.UnhandledException event, but the application still crashes. Even when i attach the debugger, visual studio just tells me "The remote connection to the device has been lost" when the exception occurs.. Since I didn't succeed to catch the exception in the managed environment, I tried to make sense out of the Error Reporter log file. But this doesn't make any sense, the only consistent this about the error is the application where it occurs in. The thread where the application occurs in is unknown to me, the module where the error occurs differs from time to time (I've seen my application.exe, WS2.dll, netcfagl3_5.dll and mscoree3_5.dll), even the error code is not always the same. (most of the time it's 0xC0000005, but i've also seen an 0X80000002 error, which is a warning accounting the first byte?) I tried debugging through bugtrap, but strangely enough this crashes with the same error code (0xC0000005). I tried to open the kdmp file with visual studio, but i can't seem to make any sense out of this because it only shows me disassembler code when i step into the error (unless i have the right .pbb files, which i don't). Same goes for WinDbg. To make a long story short: I frankly don't have a single clue where to look for this error, and I'm hoping some bright soul on stackoverflow does. I'm happy to provide some code but at this moment I don't know which piece to provide.. Any help is greatly appreciated!

  • Databinding question: DataGridView <=> XDocument (using LINQ-to-XML)

    - by Pretzel
    Learning LINQ has been a lot of fun so far, but despite reading a couple books and a bunch of online resources on the topic, I still feel like a total n00b. Recently, I just learned that if my query returns an Anonymous type, the DataGridView I'm populating will be ReadOnly (because, apparently Anonymous types are ReadOnly.) Right now, I'm trying to figure out the easiest way to: Get a subset of data from an XML file into a DataGridView, Allow the user to edit said data, Stick the changed data back into the XML file. So far I have Steps 1 and 2 figured out: public class Container { public string Id { get; set; } public string Barcode { get; set; } public float Quantity { get; set; } } // For use with the Distinct() operator public class ContainerComparer : IEqualityComparer<Container> { public bool Equals(Container x, Container y) { return x.Id == y.Id; } public int GetHashCode(Container obj) { return obj.Id.GetHashCode(); } } var barcodes = (from src in xmldoc.Descendants("Container") where src.Descendants().Count() > 0 select new Container { Id = (string)src.Element("Id"), Barcode = (string)src.Element("Barcode"), Quantity = float.Parse((string)src.Element("Quantity").Attribute("value")) }).Distinct(new ContainerComparer()); dataGridView1.DataSource = barcodes.ToList(); This works great at getting the data I want from the XML into the DataGridView so that the user has a way to manipulate the values. Upon doing a Step-thru trace of my code, I'm finding that the changes to the values made in DataGridView are not bound to the XDocument object and as such, do not propagate back. How do we take care of Step 3? (getting the data back to the XML) Is it possible to Bind the XML directly to the DataGridView? Or do I have to write another LINQ statement to get the data from the DGV back to the XDocument? Suggstions?

  • Spinner in Android crashing when visibilty changes while handling OnClick in a button

    - by Dave George
    I have a spinner in UI, which I want to hide when I handle onClick method for a button. But the application is crashing all the time. Is it that I can't use the setVisibility(View.Gone) on spinners (it is not written anywhere). If I comment it out, then application run fine. I am getting NullPointerException and I am using RelativeLayout. Also, can I do this: public void onItemSelected(AdapterView<?> arg0, View view, int pos, long arg3) { // TODO Auto-generated method stub Toast.makeText(SpinnerActivity.this,selected , Toast.LENGTH_SHORT).show(); spinner.setVisibility(View.GONE); } } Spinner code fore reference: itemsCity=getResources().getStringArray(R.array.cities_array); ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource( this, R.array.cities_array, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinnerCity.setAdapter(adapter); And here is Button code: private class BtClickListner implements View.OnClickListener{ @Override public void onClick(View v) { essEditText.setVisibility(View.GONE); spinnerCity.setEnabled(false);// Getting exception here // Also tried spinnerCity.setVisibility(View.GONE);// Exception SameBt.setVisibility(View.GONE);// This is same button for which I am handliing event, but it allows me to change tis property at run time. }

  • Get "term is undefined” error when trying to assign arrayList to List component dataSource

    - by user1814467
    I'm creating an online game where people log in and then have the list of current players displayed. When the user enters a "room" it dispatches an SFSEvent which includes a Room object with the list of users as User objects in that room. As that event's callback function, I get the list of current users which is an Array, switch the View Stack child index, and then I wrap the user list array in an ArrayList before I assign it to the MXML Spark List component's dataSource. Here's my code: My Actionscript Code Section (PreGame.as): private function onRoomJoin(event:SFSEvent):void { const room:Room = this._sfs.getRoomByName(PREGAME_ROOM); this.selectedChild = waitingRoom; /** I know I should be using event listeners * but this is a temporary fix, otherwise * I keep getting null object errors * do to the li_users list not being * created in time for the dataProvider assignment **/ setTimeout(function ():void { const userList:ArrayList = new ArrayList(room.userList); this.li_users.dataProvider = userList; // This is where the error gets thrown },1000); } My MXML Code: <?xml version="1.0" encoding="utf-8"?> <mx:ViewStack xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" initialize="preGame_initializeHandler(event)" > <fx:Script source="PreGame.as"/> <s:NavigatorContent id="nc_loginScreen"> /** Login Screen Code **/ </s:NavigatorContent> /** Start of Waiting Room code **/ <s:NavigatorContent id="waitingRoom"> <s:Panel id="pn_users" width="400" height="400" title="Users"> /** This is the List in question **/ <s:List id="li_users" width="100%" height="100%"/> </s:Panel> </s:NavigatorContent> </mx:ViewStack> However, I keep getting this error: TypeError: Error #1010: A term is undefined and has no properties Any ideas what I'm doing wrong? The arrayList has data, so I know it's not empty/null.

  • How to use a viewstate'd object as a datasource for controls on a user control

    - by user557325
    I've got a listview on a control. Each row comprises a checkbox and another listview. The outer listview is bound to a property on the control (via a method call, can't set a property as a SelectMethod on an ObjectDataSource it would appear) which is lazy loaded suchly: Public ReadOnly Property ProductLineChargeDetails() As List(Of WebServiceProductLineChargeDetail) Get If ViewState("WSProductLineChargeDetails") Is Nothing Then ViewState("WSProductLineChargeDetails") = GetWebServiceProductLineChargeDetails() End If Return DirectCast(ViewState("WSProductLineChargeDetails"), Global.System.Collections.Generic.List(Of Global.MI.Open.WebServiceProductLineChargeDetail)) End Get End Property The shape of the object referenced by the data source is something like this: (psuedocode) Product { bool Licenced; List<Charge> charges; } Charge { int property1; string property2; bool property3 . . . } The reason for the use of viewstate is this: When an one of the checkboxes on one of the outer list view rows is checked or unchecked I want to modify the object that the ODS represents (for example I'll add a couple of Charge objects to the relevant Product object) and then rebind. The problem I'm getting is that after every postback (specifically after checking or unchecking one of the rows' checkbox) my viewstate is empty. Thiss means that any changes I make to my viewstate'd object is lost. Now, I've worked out (after much googling and reading, amongst many others, Scott Mitchel's excellent bit on ViewState) that during initial databinding IsTrackingViewState is set to false. That means, I think, that assigning the return from GetWebServiceProductLineChargeDetails() to the ViewState item in my Property Get during the initial databind won't work. Mind you, even when the IsTrackingViewState is true and I call the Property Get, come the next postback, the viewstate is empty. So do you chaps have any ideas on how I keep the object referenced by the ObjectDataSource in ViewState between postbacks and update it and get those changes to stay in ViewState? This has been going on for a couple of days now and I'm getting fed up! Cheers in advance Steve

  • Linq to SQL with INSTEAD OF Trigger and an Identity Column

    - by Bob Horn
    I need to use the clock on my SQL Server to write a time to one of my tables, so I thought I'd just use GETDATE(). The problem is that I'm getting an error because of my INSTEAD OF trigger. Is there a way to set one column to GETDATE() when another column is an identity column? This is the Linq-to-SQL: internal void LogProcessPoint(WorkflowCreated workflowCreated, int processCode) { ProcessLoggingRecord processLoggingRecord = new ProcessLoggingRecord() { ProcessCode = processCode, SubId = workflowCreated.SubId, EventTime = DateTime.Now // I don't care what this is. SQL Server will use GETDATE() instead. }; this.Database.Add<ProcessLoggingRecord>(processLoggingRecord); } This is the table. EventTime is what I want to have as GETDATE(). I don't want the column to be null. And here is the trigger: ALTER TRIGGER [Master].[ProcessLoggingEventTimeTrigger] ON [Master].[ProcessLogging] INSTEAD OF INSERT AS BEGIN SET NOCOUNT ON; SET IDENTITY_INSERT [Master].[ProcessLogging] ON; INSERT INTO ProcessLogging (ProcessLoggingId, ProcessCode, SubId, EventTime, LastModifiedUser) SELECT ProcessLoggingId, ProcessCode, SubId, GETDATE(), LastModifiedUser FROM inserted SET IDENTITY_INSERT [Master].[ProcessLogging] OFF; END Without getting into all of the variations I've tried, this last attempt produces this error: InvalidOperationException Member AutoSync failure. For members to be AutoSynced after insert, the type must either have an auto-generated identity, or a key that is not modified by the database after insert. I could remove EventTime from my entity, but I don't want to do that. If it was gone though, then it would be NULL during the INSERT and GETDATE() would be used. Is there a way that I can simply use GETDATE() on the EventTime column for INSERTs? Note: I do not want to use C#'s DateTime.Now for two reasons: 1. One of these inserts is generated by SQL Server itself (from another stored procedure) 2. Times can be different on different machines, and I'd like to know exactly how fast my processes are happening.

  • Hopping from a C++ to a Perl/Unix job

    - by rocknroll
    Hi all, I have been a C++ / Linux Developer till now and I am adept in this stack. Of late I have been getting opportunities that require Perl, Unix (with knowledge of C++,shell scripting) expertise. Organizations are showing interest even though I don't have much scripting experience to boast off. The role is more in a Support, maintenance project involving SQL as well. Off late I am in a fix whether to forgo these offers or not. I don't know the dynamics of an IT organization and thus on one hand I fear that my C++ experience will be nullified and on the positive side I am getting to work on a new technology stack which will only add to my skill set. I am sure, most of you at some point of time have encountered such dilemmas and would have taken some decision. I want you to share your perspectives on such a scenario where a person is required to change his/her technology stack when changing his/her job. What are the merits and demerits in going with either of the choices? Also I know that C++ isn't going anywhere in the near future. What about perl? I have no clue as to what the future holds for perl developer? Whether there are enough opportunities for a perl developer? I am asking this question here because most of my fellow programmers face this career choice dilemma. Thanks.

  • ASP.NET Emails blocked by Spam filter on Exchange

    - by Amadiere
    I'm trying to send an email via some C# ASP.NET code. This is being sent to our internal mailrelay server, with our standard "from" address (e.g. [email protected]). In some instances, this is getting through OK, in others, it's getting blocked by the Spam Filter. An example of our Web.config <mailSettings> <smtp from="[email protected]"> <network host="mailrelay.domain.com" defaultCredentials="true" /> </smtp> </mailSettings> I've spoken with our Exchange Server team and they inform me that on occasions, our mail looks sufficiently like spam and is automatically blocked. The algorithm appears to be points based and blocks on a score of 45. 20 points are instantly added because our system is not sending the hostname with the domain name suffixed. e.g. the server is hoping for myServerName.domain.com, but despite being part of that domain, the server is sending from myServerName. I've been asked to look at altering the EHLO string that is sent and/or influencing the host so that it is its fully qualified name. However, this makes little sense to me, and although I understand the concept of what I need to change - I don't know where to begin looking for the fix.

  • Strange activity stack behavior when using MapActivity

    - by AndroidDev
    I have the following activity structure in my application A simple "splash screen" activity is started when the application is fired up (let's call it "Splash"). This activity starts the main activity when the user presses a button (I will call it "Main"). Main can in turn start two activities from the menu. The first activity presents a simple form (let's call this one "Form"), the second is a MapActivity that presents a map (it is called "Map"). Main, Form, and Map are declared exactly the same in the manifest: <activity android:name="fully qualified activity class" android:screenOrientation="landscape" android:configChanges="keyboard|keyboardHidden|orientation" > <intent-filter> <action android:name="android.intent.action.DEFAULT" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> When Main is active and I start Form and press "back", Main comes up again. Pressing "back" again brings up "Splash". Nothing strange here. Now comes the strange part: when I am in Main, start Map, and press "back", Main comes up as expected. But pressing "back" again just restarts Main. A second press on "back" is needed to bring me back to Splash! So it seems that starting the Map activity somehow results in Main ending up on the activity stack twice while starting the Form activity does not! Both Form and Map are started like this: startActivity(new Intent(this, MyActivity.class)); I don not catch the back key in any activity. Any clues on what is going on or how to debug this?

  • AutoCompleteTextView not displaying result even when the ArrayAdapter is updated

    - by cant0na
    I'm trying to get an AutoCompleteTextView(ACTV) to display results I'm a getting from a network resource. I have set the completion-treshold to 2 and I can see that the request is fired when I enter to characters. The result I am getting is the correct one. Lets say I write "ca", and I get the result "car" as an autocompletion. I have a callback function which receives the result from an AsyncTask and puts the result into the ArrayAdapter. Then I call .showDropDown() on the ACTV and an empty dropdown is shown (half the size of a normal element). Then if I enter the last letter "r" and the ACTV shows "car", the dropdown is shown and the result is suddenly in the list. The same happens if I have entered two characters (which returns a valid result), and the remove the last letter. When the letter is removed, "car" is shown as an autocompletion value. Has anyone had this problem? It looks like the adapter is filled with the result, but the result does not show until the next action I do. I have also tried to run .notifyDataSetChanged() after I have added the result to the adapter, but that should not be needed, or?

  • 3n+1 problem at UVa

    - by ShahradR
    Hello, I am having trouble with the first question in the Programming Challenges book by Skiena and Revilla. I keep getting a "Wrong Answer" error message, and I don't know why. I've ran my code against the sample input, and I keep getting the right answer. Anyways, if anyone could help me, I would really appreciate it :) Here is the problem URL: http://uva.onlinejudge.org/index.php?option=com_onlinejudge&Itemid=8&category=29&page=show_problem&problem=36 And here is the code:` import java.util.Scanner; public class Main { static Scanner kb = new Scanner(System.in); public static void main(String[] args) { while (kb.hasNext()) { long[] numericalInput = {0, 0}; long i = kb.nextLong(); long j = kb.nextLong(); if (i > j) { numericalInput[0] = i; numericalInput[1] = j; } else { numericalInput[0] = j; numericalInput[1] = i; } long maxIterations = 0; for (long n = numericalInput[0]; n <= numericalInput[1]; n += 1) { if (maxIterations < returnIterations(n)) maxIterations = returnIterations(n); } System.out.println(i + " " + j + " " + maxIterations); } System.exit(0); } public static long returnIterations(long num) { long iterations = 0; while (num != 1) { if (num % 2 == 0) num = num / 2; else num = 3 * num + 1; iterations += 1; } iterations += 1; return iterations; } } ` EDIT: I think the problem is with the output. I tried to make it accept all the input first and then display all the answers at once, but I didn't know the terminating condition. I resorted to this method, but I'm not sure that's what the judge wants...

  • XML generation with java, trying to copy the whole node

    - by Pawel Mysior
    I've got an xml document that filled with people (parent node is "students", and there are 25+ "student" nodes). Each student looks like this: <student> <name></name> <surname></surname> <grades> <subject name=""> <small_grades></small_grades> <final_grade></final_grade> </subject> <subject name=""> <small_grades></small_grades> <final_grade></final_grade> </subject> </grades> <average></average> </student> Basically, what I want to do ('ve been asked to do) is to make a program that would get 3 students with the best average. While parsing the document and getting three best students isn't too difficult, the XML generation is a pain in the ass. Right now, what I'm doing is getting every single node from student and recreating it to a new file. Is there a way to copy the whole student node with everything that's in it? Regards, Paul

  • How to debug anomalous C memory/stack problems

    - by EBM
    Hello, Sorry I can't be specific with code, but the problems I am seeing are anomalous. Character string values seem to be getting changed depending on other, unrelated code. For example, the value of the argument that is passed around below will change merely depending on if I comment out one or two of the fprintf() calls! By the last fprintf() the value is typically completely empty (and no, I have checked to make sure I am not modifying the argument directly... all I have to do is comment out a fprintf() or add another fprintf() and the value of the string will change at certain points!): static process_args(char *arg) { /* debug */ fprintf(stderr, "Function arg is %s\n", arg); ...do a bunch of stuff including call another function that uses alloc()... /* debug */ fprintf(stderr, "Function arg is now %s\n", arg); } int main(int argc, char *argv[]) { char *my_arg; ... do a bunch of stuff ... /* just to show you it's nothing to do with the argv array */ my_string = strdup(argv[1]); /* debug */ fprintf(stderr, "Argument 1 is %s\n", my_string); process_args(my_string); } There's more code all around, so I can't ask for someone to debug my program -- what I want to know is HOW can I debug why character strings like this are getting their memory changed or overwritten based on unrelated code. Is my memory limited? My stack too small? How do I tell? What else can I do to track down the issue? My program isn't huge, it's like a thousand lines of code give or take and a couple dynamically linked external libs, but nothing out of the ordinary. HELP! TIA!

  • Selenium RC throws sessionsid should not be null exception, phpunit 3.4 bug only?

    - by user342775
    I am looking to migrate my selenium RC tests to using PHPUnit 3.4.12 from PHPUnit 3.3.2 The selenium test will fail with an exception of the following when I use assertTextPresent() PHPUnit_Framework_Exception: Response from Selenium RC server for getLocation(). ERROR Server Exception: sessionId should not be null; has this session been started yet?. For example: public function testSending($browser) { ... $browser->click("send"); $browser->waitForPageToLoad("30000"); $browser->assertTextPresent("text"); } Below is the selenium RC log (running on Windows): 15:40:19.676 INFO - Command request: isTextPresent[text, ] on session 153d03a123c42098711994f43c2db34 15:40:19.691 INFO - Got result: OK,false on session 153d023a123c42098711994f43cdb34 15:40:19.879 INFO - Command request: testComplete[, ] on session 153d023a123c4298711994f43c2db34 15:40:19.879 INFO - Killing Firefox... 15:40:20.269 INFO - Got result: OK on session 153d023a123c42098711994f43c2db34 15:40:20.472 INFO - Command request: getLocation[, ] on session null 15:40:20.472 ERROR - Exception running 'getLocation 'command on session null java.lang.NullPointerException: sessionId should not be null; has this session been started yet? As you can see, the test should have completed as indicated by the "Killing Firefox" bit, but it instead continued to do something else and triggered the getLocation[, ] command which caused the exception. I have tried the same test with PHPUnit 3.3.2 which did not produce this problem - the test would happily end without the getLocation(). Any ideas? thanks

  • VBScript Catching Erroring Varialble Value

    - by Soren
    I have a VB Script (.vbs file) that is just a simple directory listing of a drive. It will the base of a drive back up script. But when running it as it is below, I am getting a Permission Denied error on some folder. What I need to find is what that folder is so I can figure out what the problem is with the folder. The line that is giving the error is "For Each TempFolder In MoreFolders". So what I am trying to figure out is how to WScript.Echo the current path (objDirectory) if there is an error. I am not sure if it matters much, but just in case, the error that I am getting is Permission Denied 800A0046 on line 12. So some folder, I do not know which one, is not letting me look inside. Set WSShell = WScript.CreateObject("WScript.Shell") Set objFSO = CreateObject ("Scripting.FileSystemObject") Dim FolderArr() FolderCount = 0 TopCopyFrom = "G:\" Sub WorkWithSubFolders(objDirectory) Set MoreFolders = objDirectory.SubFolders 'The next line is where the error occurs (line 12) For Each TempFolder In MoreFolders FolderCount = FolderCount + 1 ReDim Preserve FolderArr(FolderCount) FolderArr(FolderCount) = TempFolder.Path ' WScript.Echo TempFolder.Path WorkWithSubFolders(TempFolder) Next End Sub ReDim Preserve FolderArr(FolderCount) FolderArr(FolderCount) = TopCopyFrom Set objDirectory = objFSO.GetFolder(TopCopyFrom) WorkWithSubFolders(objDirectory) Set objDirectory = Nothing WScript.Echo "FolderCount = " & FolderCount WScript.Sleep 30000 Set objFSO = Nothing Set WSShell = Nothing
