  • Storing info in a PostgreSQl database issue

    - by MrEnder
    Ok I am making a registry for my website. First page asks for some personal info if($error==false) { $query = pg_query("INSERT INTO chatterlogins(firstName, lastName, gender, password, ageMonth, ageDay, ageYear, email, createDate) VALUES('$firstNameSignup', '$lastNameSignup', '$genderSignup', md5('$passwordSignup'), $monthSignup, $daySignup, $yearSignup, '$emailSignup', now());"); $query = pg_query("INSERT INTO chatterprofileinfo(email, lastLogin) VALUES('$emailSignup', now());"); $userNameSet = $emailSignup; $_SESSION['$userNameSet'] = $userNameSet; header('Location: signup_step2.php'.$rdruri); } The first query works. The second query works but doesn't save the email... the session doesn't work but the header works and sends me to the next page I get no errors even if I comment out header next page @session_start(); $conn = pg_connect("host=localhost dbname=brittains_db user=brittains password=XXXX" ); $signinCheck = false; $checkForm = ""; if(isset($_SESSION['$userName'])) { $userName = $_SESSION['$userName']; $signinCheck = true; $query = pg_query("UPDATE chatterprofileinfo SET lastLogin='now()' WHERE email='$userName'"); } if(isset($_SESSION['$userNameSet'])) { $userName = $_SESSION['$userNameSet']; $signinCheck = true; $query = pg_query("UPDATE chatterprofileinfo SET lastLogin='now()' WHERE email='$userName'"); } This is the top starting the session depending on if your logged in or not. then if I enter in the info here and put it through this if($error==false) { $query = pg_query("UPDATE chatterprofileinfo SET aboutSelf='$aboutSelf', hobbies='$hobbies', music='$music', tv='$tv', sports='$sports', lastLogin='now()' WHERE email='$userName'") or exit(pg_last_error()); //header('Location: signup_step3.php'.$rdruri); } nothing shows up for on my database from this. I have no idea where I went wrong the website is http://opentech.durhamcollege.ca/~intn2201/brittains/chatter/

  • monitoring iphone 3g/wifi bandswitch

    - by user262325
    Hello everyone I hope add the function to monitor iphone used 3g/wifi band switch. I know I can do these in my app, but I wonder if there is way to monitor all band switch usage of iPhone? I noticed that there is an app http://itunes.apple.com/ca/app/download-meter-for-wi-fi-gprs/id327227530?mt=8 It claims: Works with any carrier (iPods are supported too!). Requires no login/password to your carrier's site. Does not require Internet connection to get traffic usage statistics (works even in Airplane mode) because it gets information on traffic from the device, not a carrier; this means it won't cost you anything to view current traffic consumed, even while roaming in a location where traffic is very expensive. Allows the user to adjust consumed traffic for today or the current month to match traffic amounts reported by your carrier. Stats on the screen are updated every second. Measures traffic in real time with up to byte precision. Separates traffic into incoming and outgoing, Wi-Fi traffic and mobile Internet traffic. It looks like it gets the band switch info from carrier site, but they also said it gets info from device. I am really confused. Welcome any comment. Thanks interdev

  • Run WCF ServiceHost with multiple contracts

    - by Sam
    Running a ServiceHost with a single contract is working fine like this: servicehost = new ServiceHost(typeof(MyService1)); servicehost.AddServiceEndpoint(typeof(IMyService1), new NetTcpBinding(), "net.tcp://127.0.0.1:800/MyApp/MyService1"); servicehost.Open(); Now I'd like to add a second (3rd, 4th, ...) contract. My first guess would be to just add more endpoints like this: servicehost = new ServiceHost(typeof(MyService1)); servicehost.AddServiceEndpoint(typeof(IMyService1), new NetTcpBinding(), "net.tcp://127.0.0.1:800/MyApp/MyService1"); servicehost.AddServiceEndpoint(typeof(IMyService2), new NetTcpBinding(), "net.tcp://127.0.0.1:800/MyApp/MyService2"); servicehost.Open(); But of course this does not work, since in the creation of ServiceHost I can either pass MyService1 as parameter or MyService2 - so I can add a lot of endpoints to my service, but all have to use the same contract, since I only can provide one implementation? I got the feeling I'm missing the point, here. Sure there must be some way to provide an implementation for every endpoint-contract I add, or not?

  • How to prove writing specifications beats code cowboys?

    - by Andrew Grant
    So I have a problem. Or rather my friend has a problem, since I would never write about my company on an internet forum. At my friend's company specification writing is, shall we say, a little underused. There's a deeply ingrained culture of writing code first and asking questions later, whether it's for a library routine or a new tool to inflict on their long suffering designers. This of course leads to situations where functionality is partially correct, incorrect, or just completely missing ("oh, just save before trying anything you may want to undo"). This usually results in a loss of productivity for those poor designers, or beta periods where bug-fixing is largely spent implementing things correctly. My friend's found his suggestions of writing (and testing against) specifications to be generally well received. Most of his colleagues have embraced the wonderful feeling of discovering false-assumptions on paper, instead of at 11pm on a Sunday in the middle of beta. Viva La Revolution! However there are a few who poo-poo anything that stands between their task and a keyboard. They laugh at the thought of actually designing anything, and write code with merry abandon. Mostly these are senior, long employed developers, reluctant to "waste time". The problem is that this second group of heretics invariably produce things (or at least something) quicker than the first. Subsequently this becomes justification along the lines of "It's pointless to write specifications for something as simple as an image resizer! Oh and those bugs where width!=height or the image uses RLE just need a few tweaks". And now the question :) Other than saying "told you so" at the end of a project, what are some good short-term ways to demonstrate how the practice of writing functional or technical specifications leads to better software in the long run? Cheers!

  • Looking for a good world map generation algorithm

    - by FalconNL
    I'm working on a Civilization-like game and I'm looking for a good algorithm for generating Earth-like world maps. I've experimented with a few alternatives, but haven't hit on a real winner yet. One option is to generate a heightmap using perlin noise and add water at a level so that about 30% of the world is land. While perlin noise (or similar fractal-based techniques) are frequently used for terrain and is reasonably realistic, it doesn't offer much in the way of control over the number, size and position of the resulting continents, which I'd like to have from a gameplay perspective. See http://farm3.static.flickr.com/2792/4462870263_ff26c40365_o.jpg for an example (sorry, can't post pictures yet). A second option is to start with a randomly positioned one-tile seed (I'm working on a grid of tiles), determine the desired size for the continent and each turn add a tile that is horizontally or vertically adjacent to the existing continent until you've reached the desired size. Repeat for the other continents. This technique is part of the algorithm used in Civilization 4. The problem is that after placing the first few continents, it's possible to pick a starting location that's surrounded by other continents, and thus won't fit the new one. Also, it has a tendency to spawn continents too close together, resulting in something that looks more like a river than continents. See http://farm5.static.flickr.com/4069/4462870383_46e86b155c_o.jpg for an example. Does anyone happen to know a good algorithm for generating realistic continents on a grid-based map while keeping control over their number and relative sizes?

  • Singletons, thread safety and structuremap

    - by Ben
    Hi, Currently I have the following class: public class PluginManager { private static bool s_initialized; private static object s_lock = new object(); public static void Initialize() { if (!s_initialized) { lock (s_lock) { if (!s_initialized) { // initialize s_initialized = true; } } } } } The important thing here is that Initialize() should only be executed once whilst the application is running. I thought that I would refactor this into a singleton class since this would be more thread safe?: public sealed class PluginService { static PluginService() { } private static PluginService _instance = new PluginService(); public static PluginService Instance { get { return _instance; } } private bool s_initialized; public void Initialize() { if (!s_initialized) { // initialize s_initialized = true; } } } Question one, is it still necessary to have the lock here (I have removed it) since we will only ever be working on the same instance? Finally, I want to use DI and structure map to initialize my servcices so I have refactored as below: public interface IPluginService { void Initialize(); } public class NewPluginService : IPluginService { private bool s_initialized; public void Initialize() { if (!s_initialized) { // initialize s_initialized = true; } } } And in my registry: ForRequestedType<IPluginService>() .TheDefaultIsConcreteType<NewPluginService>().AsSingletons(); This works as expected (singleton returning true in the following code): var instance1 = ObjectFactory.GetInstance<IPluginService>(); var instance2 = ObjectFactory.GetInstance<IPluginService>(); bool singleton = (instance1 == instance2); So my next question, is the structure map solution as thread safe as the singleton class (second example). The only downside is that this would still allow NewPluginService to be instantiated directly (if not using structure map). Many thanks, Ben

  • Unit Testing.... a data provider ?

    - by TomTom
    Given problem: I like unit tests. I develop connectivity software to external systems that pretty much and often use a C++ library The return of this systems is nonndeterministic. Data is received while running, but making sure it is all correctly interpreted is hard. How can I test this properly? I can run a unit test that does a connect. Sadly, it will then process a life data stream. I can say I run the test for 30 or 60 seconds before disconnecting, but getting code ccoverage is impossible - I simply dont even comeclose to get all code paths EVERY ONCE PER DAY (error code paths are rarely run). I also can not really assert every result. Depending on the time of the day we talk of 20.000 data callbacks per second - all of which are not relly determined good enough to validate each of them for consistency. Mocking? Well, that would leave me testing an empty shell of myself because the code handling the events basically is the to be tested case, and in many cases we talk here of a COMPLEX c level structure - hard to have mocking frameworks that integrate from Csharp to C++ Anyone any idea? I am short on giving up using unit tests for this part of the application.

  • Legit? Two foreign keys referencing the same primary key.

    - by Ryan
    Hi All, I'm a web developer and have recently started a project with a company. Currently, I'm working with their DBA on getting the schema laid out for the site, and we've come to a disagreement regarding the design on a couple tables, and I'd like some opinions on the matter. Basically, we are working on a site that will implement a "friends" network. All users of the site will be contained in a table tblUsers with (PersonID int identity PK, etc). What I am wanting to do is to create a second table, tblNetwork, that will hold all of the relationships between users, with (NetworkID int identity PK, Owners_PersonID int FK, Friends_PersonID int FK, etc). Or conversely, remove the NetworkID, and have both the Owners_PersonID and Friends_PersonID shared as the Primary key. This is where the DBA has his problem. Saying that "he would only implement this kind of architecture in a data warehousing schema, and not for a website, and this is just another example of web developers trying to take the easy way out." Now obviously, his remark was a bit inflammatory, and that have helped motivate me to find an suitable answer, but more so, I'd just like to know how to do it right. I've been developing databases and programming for over 10 years, have worked with some top-notch minds, and have never heard this kind of argument. What the DBA is wanting to do is instead of storing both the Owners_PersonId and Friends_PersonId in the same table, is to create a third table tblFriends to store the Friends_PersonId, and have the tblNetwork have (NetworkID int identity PK, Owner_PersonID int FK, FriendsID int FK(from TBLFriends)). All that tblFriends would house would be (FriendsID int identity PK, Friends_PersonID(related back to Persons)). To me, creating the third table is just excessive in nature, and does nothing but create an alias for the Friends_PersonID, and cause me to have to add (what I view as unneeded) joins to all my queries, not to mention the extra cycles that will be necessary to perform the join on every query. Thanks for reading, appreciate comments. Ryan

  • Setting an instanced class property overwrites the property in all instances.

    - by Peter Moore
    I have two instances of a class. Setting a property in the first instance will set it for the second instance too. Why? It shouldn't. The property is not a "prototype property". Check the code below, what happens to Peter Griffin? Two objects are created and given the name "Peter Griffin" and "Roger Moore" but the alert boxes will say "Peter Moore" and "Roger Moore". What happened to Peter Griffin? var BaseClass = function(){ this.name = ""; this.data = {}; this.data.lastname = ""; } var ExtendedClass = function(){ this.setName = function(fname, lname){ this.name = fname; this.data.lastname = lname; } this.hello = function(){ alert("Full name: " + this.name + " " + this.data.lastname); } } ExtendedClass.prototype = new BaseClass(); pilot = new ExtendedClass(); driver = new ExtendedClass(); pilot.setName("Peter", "Griffin"); driver.setName("Roger", "Moore"); pilot.hello(); // Full name: Peter Moore driver.hello(); // Full name: Roger Moore

  • C# inaccurate timer?

    - by Ivan
    Hi there, I'm developing an application and I need to get the current date from a server (it differs from the machine's date). I receive the date from the server and with a simple Split I create a new DateTime: globalVars.fec = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, int.Parse(infoHour[0]), int.Parse(infoHour[1]), int.Parse(infoHour[2])); globalVars is a class and fec is a public static variable so that I can access it anywhere in the application (bad coding I know...). Now I need to have a timer checking if that date is equal to some dates I have stored in a List and if it is equal I just call a function. List<DateTime> fechas = new List<DateTime>(); Before having to obtain the date from a server I was using computer's date, so to check if the dates matched I was using this: private void timerDatesMatch_Tick(object sender, EventArgs e) { DateTime tick = DateTime.Now; foreach (DateTime dt in fechas) { if (dt == tick) { //blahblah } } } Now I have the date from the server so DateTime.Now can't be used here. Instead I have created a new timer with Interval=1000 and on tick I'm adding 1 second to globalVars.fec using: globalVars.fec = globalVars.fec.AddSeconds(1); But the clock isn't accurate and every 30 mins the clock loses about 30 seconds. Is there another way of doing what I'm trying to do? I've thought about using threading.timer instead but I need to have access to other threads and non-static functions. Thanks in advance, Ivan

  • iPhone TableView alternative options for Check Mark Accessory

    - by jimsis
    I'm looking for the best approach to this problem. In my tableview I have a list of options from which you can select one and only one. The problem is the selection to choose is not obvious without displaying more details on the option. If I use the disclosure indicator or button for the more detail, I lose the checkmark functionality. In searching around I see some have used the cell Image as a work around. I see others instead of using the standard disclosure button have created custom disclosure button looking like a checkmark. Haven't seen this one but is it viable (HIG) to add a button in the cell ('more info') to launch the next tableview. My thought was to use a disclosure indicator and on the second view in the navigation bar (where the edit button usually is) add a 'selectMe' button. I think I am probably manage to code either of the above, am just asking for information on what is the best (HIG) way. Example Option 1 Option 2 Option 3 (x) Option 4 Where x is the checked one But in order to know which is the best choice you need to see Option 3 (Header) Option 3-a Option 3-b Option 3-c Option 3-d Where even at this level option 3-c might have additional information. Any guidance you can provide would appreciated.

  • PHP4 including file during session

    - by Matherw
    I am trying to put second language on my webpage. I decided to use different files for different languages told apart by path - language/pl/projects.ln contains Polish text, language/en/projects.ln - English. Those extensions are just to tell language files from other, the content is simple php: $lang["desc"]["fabrics"]["title"] = "MATERIALY"; $lang["desc"]["fabrics"]["short_text"] = "Jakis tam tekst na temat materialów"; $lang["desc"]["services"]["title"] = "USLUGI"; $lang["desc"]["services"]["short_text"] = "Jakis tam tekst na temat uslóg"; And then on the index page I use it like so: session_start(); if (isset($_SESSION["lang"])) { $language = $_SESSION["lang"]; } else { $language = "pl"; } include_once("language/$language/projects.ln"); print $lang["desc"]["fabrics"]["title"]; The problem is that if the session variable is not set everything works fine and array item content is displayed but once I change and set $_SESSION["lang"] nothing is displayed. I tested if the include itself works as it should by putting print "sth"; at the beginning of projects.ln file and that works all right both with $_SESSION["lang"] set and unset. Please help.

  • WPF MVVM Picklist Example

    - by Tim
    Hi, I am looking for a way of easily maintaining a list of Users belonging to a particular Group. I have thought about using a Picklist, where I have 2 listboxs, the first contains a list of Users the second a list of Users belonging to the Group. There will be buttons to allow the adding and removing of selected Users from the Group. As users are added they move from the left listbox to the right, as they are removed they are move from the right to the list. This is pretty common situation. Do you know of any examples of doing this in WPF using the MVVM pattern? I am having difficulty understand how the binding may work to my View Model and Business Entities. Especially persisting the data back to the database. I am using stored procedure calls to do the CRUD logic, so I need to keep a list of which Users had been removed so I can delete them. Is this the best way to perform this functionality or is there a better way. I simply want to pick from a list (the list may be large).

  • Memory leak when using Workflow 4.0 SqlWorkflowInstanceStore and PersistableIdleAction.Unload

    - by Rohland
    Hi, This particular problem is driving me nuts. I wonder if anyone has experienced a similar problem. If I load up a workflow then unload it and perform a memory snapshot then the result is predictable - my workflow is no longer in memory. However, if I load up a workflow and set the PersistableIdle action to PersistableIdleAction.Unload and let the workflow idle the workflow remains in memory even though the Unload action fires. I used ANTS Memory Profiler to debug this issue. This is the object retention graph outputted showing that an internal object is hanging onto my workflow instance. Can anyone else verify this problem? My code amounts to the following: Create SqlWorkflowInstanceStore and setup lock owner handle -- At this point I take a memory snapshot Create an instance of Workflow1 Set the PersistableIdle action Apply the instancestore to Workflow1 Setup action event handlers for Idle, Unload, UnhandledException etc. Persist the workflow instance Run the workflow instance Wait for instance to idle (caused by Delay activity) Ensure the Unload action is fired -- At this point I take a second memory snapshot From the above image, it is clear that the only object referencing Workflow1 is some internal event handlers result which I have no ability to dispose of. Any clues?

  • WPF custom BalloonTips problem with multithreading

    - by Erika
    Hi, I have read other related question but i cant really get them to relate to this so I thought it were best to ask, Im pretty new to WPF and so on so please bear with me. I am using this http://www.codeproject.com/KB/WPF/wpf_notifyicon.aspx api to work with custom WPF Windows (in particular FancyBalloon). However, i'm coming across the following problem, I seem unable to start off BalloonTips in a separate thread ( i need this because i'm parsing emails and hence if there are 3 emails for instance, it displays the first email (that works fine), but when it comes to the second email it crashes with a TargetInvocationException , {"Specified element is already the logical child of another element. Disconnect it first."}. Thing is, im supposedly working with the same instance and i have attempted calling it to close it before, disposing it etc but to no avail. (then again if i dispose it, i cant create another instance as apparently WPF UI components must be called from a static thread so throughout the looping of emails + displaying balloon, i am trying to use the same BalloonTip. Any suggestions please? I am really at a loss here and i've been on it for quite a while now :/ I was wondering if there was anyone

  • WCF sending the same exception even if the service endpoint address is valid

    - by ALexr111
    Hi, I'm running into a really strange problem with WCF. I need to implement some recovery behavior for WCF service if not reachable endpoint IP address received or service can not bind. The flow is simple if the application fail on exception on service creation it terminate it and request from user another IP address and perform another attempt to create the service. (The code snippet below). If the address is not valid I get "A TCP error (10049: The requested address is not valid in its context) occurred while listening on IP Endpoint=.121.10.11.11" exception, but for any reason if I try the second attempt with valid address I've got the same exception with wrong IP address from previous attempt. Here is a code: ServiceHost service = null; try { Uri[] uris = { new Uri(Constants.PROTOCOL + "://" + address + ":" + port) }; service = new ServiceHost(typeof(IRemoteService), uris); NetTcpBinding tcpBinding = WcfTcpRemoteServicesManager.LessLimitedNewNetTcpBinding(int.MaxValue, int.MaxValue, int.MaxValue); ServiceEndpoint ep = service.AddServiceEndpoint(implementedContract.FullName, tcpBinding, serviceName); var throttle = service.Description.Behaviors.Find<ServiceThrottlingBehavior>(); if (throttle == null) { throttle = new ServiceThrottlingBehavior { MaxConcurrentCalls = Constants.MAX_CONCURRENT_CALLS, MaxConcurrentSessions = Constants.MAX_CONCURRENT_SESSIONS, MaxConcurrentInstances = Constants.MAX_CONCURRENT_INSTANCES }; service.Description.Behaviors.Add(throttle); } service.Open(); } catch (Exception e) { _debugLog.WriteLineMessage( "Failed to open or create service exception. Exception message:" + e.Message); if (service!=null) { try { service.Close(); } catch (Exception) { service.Abort(); service.Close(); throw e; } } } Thanks

  • WPF Toolkit Charting and IndependentValueBinding, IndependentValuePath

    - by Joel Barsotti
    So I'm having a problem with the charting engine from the WPF toolkit. We haven't moved our data to a proper object model, so the ItemSource is backed with a DataView. First attempt <chartingToolkit:ScatterSeries x:Name="TargetSeries" DataPointStyle="{StaticResource TargetStyle}" ItemsSource="{Binding Path=TargetSeriesData}" IndependentValueBinding="{Binding Path=TargetSeries_X}" DependentValueBinding="{Binding Path=TargetSeries_X}" /> This crashes because, I believe, it thinks the bindings are the values to plot or some sort of mismatch. Second attempt <chartingToolkit:ScatterSeries x:Name="TargetSeries" DataPointStyle="{StaticResource TargetStyle}" ItemsSource="{Binding Path=TargetSeriesData}" IndependentValuePath="{Binding Path=TargetSeries_X}" DependentValuePath="{Binding Path=TargetSeries_X}" /> This crashes during the init step becaue the Path properties aren't backed with dependency properties and therefore cannot be bound. Third attempt <chartingToolkit:ScatterSeries x:Name="TargetSeries" DataPointStyle="{StaticResource TargetStyle}" ItemsSource="{Binding Path=TargetSeriesData}" IndependentValuePath="targetFooXColumnName" DependentValuePath="targetFooYColumnName" /> Now this works! But I wanted to use the binding so I can switch from using the targetFooXColumnName to the targetFooBarXColumnName. So this solution will cause a whole lot of hacky looking code to switch the Path's manually. Anyway to fix this? Can I use some sort of convertor to get the Binding properties to correctly pull the data from the columns in the DataView? Thanks, Joel

  • Need to replace 3rd party WinForm controls, what's the closet WPF equivalent?

    - by Refracted Paladin
    I am tired of Windows Forms...I just am. I am not trying to start a debate on it I am just bored with it. Unfortunately we have become dependent on 4 controls in DevExpress XtraEditors. I have had nothing but difficulties with them and I want to move on. What I need now is what the closet replacement would be for the 4 controls I am using. Here they are: LookUpEdit - this is a dropdown that filters the dropdown list as you type. MemoExEdit - this is a textbox that 'pops up' a bigger area when it has focus CheckedComboBoxEdit - this is a dropdown of checkboxes. CheckedListBoxControl - this is a nicely columned list box of checkboxes This is a LOB app that has tons of data entry. In reality, the first two are nice but not essential. The second two are essential in that I would either need to replicate the functionality or change the way the users are interacting with that particular data. I am looking for help in replicating these in a WPF environment with existing controls(codeplex etc) or in straight XAML. Any code or direction would be greatly appreciated but mostly I am hoping to avoid any commercial 3rd party WPF and would instead like to focus on building them myself(but I need direction) or using Codeplex

  • In Reporting Services how to filter drop down parameter list in based on other selected parameter?

    - by Lee Englestone
    Question In a Reporting Services Report, How do I filter a second drop down list of cars to only show cars whose ManufacturerId is equal the selected Manufacturer (from the first drop down list)? Report Datasets I have 2 datasets. Dataset 1. A list of Manufacturers. From a stored procedure Report_Manufacturers_P Dataset 2. A list of Cars, including a column called Manufacturers id. From a stored procedure Report_Cars_P Report Parameters On the Report I have 2 Parameters. Parameter 1. ManufacturerId. Set from A drop down list of Manufacturers (DataSet 1). Parameter 2. CarId. Set from A drop down list of Cars (DataSet 2). I've tried.. Creating another sproc called Report_Manufacturer_Cars_P that takes the ManufacturerId as an integer and returns a list of cars made by that manufacturer. Any Ideas. As selecting a Manufacturer doesn't seem to want to kick off anything that filters the Car list? Thanks in advance, -- Lee

  • C# Application Calling Powershell Script Issues

    - by Ben
    Hi, I have a C# Winforms application which is calling a simple powershell script using the following method: Process process = new Process(); process.StartInfo.FileName = @"powershell.exe"; process.StartInfo.Arguments = String.Format("-noexit \"C:\Develop\{1}\"", scriptName); process.Start(); The powershell script simply reads a registry key and outputs the subkeys. $items = get-childitem -literalPath hklm:\software foreach($item in $items) { Write-Host $item } The problem I have is that when I run the script from the C# application I get one set of results, but when I run the script standalone (from the powershell command line) I get a different set of results entirely. The results from running from the c# app are: HKEY_LOCAL_MACHINE\software\Adobe HKEY_LOCAL_MACHINE\software\Business Objects HKEY_LOCAL_MACHINE\software\Helios HKEY_LOCAL_MACHINE\software\InstallShield HKEY_LOCAL_MACHINE\software\Macrovision HKEY_LOCAL_MACHINE\software\Microsoft HKEY_LOCAL_MACHINE\software\MozillaPlugins HKEY_LOCAL_MACHINE\software\ODBC HKEY_LOCAL_MACHINE\software\Classes HKEY_LOCAL_MACHINE\software\Clients HKEY_LOCAL_MACHINE\software\Policies HKEY_LOCAL_MACHINE\software\RegisteredApplications PS C:\Develop\RnD\SiriusPatcher\Sirius.Patcher.UI\bin\Debug When run from the powershell command line I get: PS M: C:\Develop\RegistryAccess.ps1 HKEY_LOCAL_MACHINE\software\ATI Technologies HKEY_LOCAL_MACHINE\software\Classes HKEY_LOCAL_MACHINE\software\Clients HKEY_LOCAL_MACHINE\software\Equiniti HKEY_LOCAL_MACHINE\software\Microsoft HKEY_LOCAL_MACHINE\software\ODBC HKEY_LOCAL_MACHINE\software\Policies HKEY_LOCAL_MACHINE\software\RegisteredApplications HKEY_LOCAL_MACHINE\software\Wow6432Node PS M: The second set of results match what I have in the registry, but the first set of results (which came from the c# app) don't. Any help or pointers would be greatly apreciated :) Ben

  • HTML inside webView

    - by Samuh
    I am posting some data to a server using DefaultHttpClient class and in the response stream I am getting a HTML file. I save the stream as a string and pass it onto another activity which contains a WebView to render this HTML on the screen: response = httpClient.execute(get); InputStream is = response.getEntity().getContent(); BufferedReader br = new BufferedReader(new InputStreamReader(is,"utf-8")); StringBuffer sb = new StringBuffer(); String line; while((line=br.readLine())!=null){ sb.append(line); sb.append("\n"); } is.close(); Intent intent = new Intent(this,Trial.class); intent.putExtra("trial",sb.toString()); startActivity(intent); Log.i("SB",sb.toString()); In Second Activity, the code to load the WebView reads: WebView browser = ((WebView)findViewById(R.id.trial_web)); browser.getSettings().setJavaScriptEnabled(true); browser.loadData(html,"text/html", "utf-8"); When I run this code, the WebView is not able to render the HTML content properly. It actually shows the HTML string in URL encoded format on the screen. Interestingly, If I copy the Loggers output to HTML file and then load this HTML in my WebView(using webview.loadurl(file:///assets/xyz.html)) everything works fine. I suspect some problem with character encoding. What is going wrong here? Please help. Thanks.

  • jQuery datepicker validation message issue

    - by Abhishek
    Hi, I'm using the jquery datepicker plugin at http://plugins.jquery.com/project/datepick with the datepicker validation plugin. <script id="frmValidation" type="text/javascript"> $(document).ready(function(){ var validator = $("#frmTest").validate({ rules:{ fname: "required", dobPicker: "required" }, messages:{ fname: "Please enter a name", dobPicker: "Select a date" }, }); $('#dobPicker').datepick(); $.datepick.setDefaults({showOn: 'both', dateFormat: 'dd-mm-yy', yearRange:'1900:2010'}); }); </script> And the body of the document is as follows : <form id="frmTest" action="" method="post"> <div id="error-list"></div> <div class="form-row"> <span class="label"><label for="fname">Name</label></span> <input type="text" name="fname" /> </div> <div class="form-row"> <span class="label"><label for="dobPicker">DOB</label></span> <input type="text" id="dobPicker" name="dobPicker" style="margin-left: 4px;"/> </div> <div class="form-row"> <input type="submit" name="submit" value="submit"/> </div> </form> The form validates the first time but the error message for the datepicker does not disappear immediately a date is selected.. however it goes away if the date is selected the second time. Any help to make it go the first time a date is selected will be appreciated
