• Unable to record from USB sound card line-in connector

  - by tete

  I've been googling and struggling with this for a while but haven't been able to make this work. I bought a USB sound card (Encore ENMAB 8-CM) to record from its line-in connector. I'm not sure which input to pick in Audicity, but I'me sure I've tested them all. These are all the available inputs I have in Audacity. But there's no sound being recorded at all. I've already checked the device is working, so I really don't know if I'm doing something wrong. Any help will be very appreciated. Cheers.

• Android: Trusting all Certificates using HttpClient over HTTPS

  - by psuguitarplayer

  Hi all, Recently posted a question regarding the HttpClient over Https (found here). I've made some headway, but I've run into new issues. As with my last problem, I can't seem to find an example anywhere that works for me. Basically, I want my client to accept any certificate (because I'm only ever pointing to one server) but I keep getting a javax.net.ssl.SSLException: Not trusted server certificate exception. So this is what I have: public void connect() throws A_WHOLE_BUNCH_OF_EXCEPTIONS { HttpPost post = new HttpPost(new URI(PROD_URL)); post.setEntity(new StringEntity(BODY)); KeyStore trusted = KeyStore.getInstance("BKS"); trusted.load(null, "".toCharArray()); SSLSocketFactory sslf = new SSLSocketFactory(trusted); sslf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER); SchemeRegistry schemeRegistry = new SchemeRegistry(); schemeRegistry.register(new Scheme ("https", sslf, 443)); SingleClientConnManager cm = new SingleClientConnManager(post.getParams(), schemeRegistry); HttpClient client = new DefaultHttpClient(cm, post.getParams()); HttpResponse result = client.execute(post); } And here's the error I'm getting: W/System.err( 901): javax.net.ssl.SSLException: Not trusted server certificate W/System.err( 901): at org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl.startHandshake(OpenSSLSocketImpl.java:360) W/System.err( 901): at org.apache.http.conn.ssl.AbstractVerifier.verify(AbstractVerifier.java:92) W/System.err( 901): at org.apache.http.conn.ssl.SSLSocketFactory.connectSocket(SSLSocketFactory.java:321) W/System.err( 901): at org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:129) W/System.err( 901): at org.apache.http.impl.conn.AbstractPoolEntry.open(AbstractPoolEntry.java:164) W/System.err( 901): at org.apache.http.impl.conn.AbstractPooledConnAdapter.open(AbstractPooledConnAdapter.java:119) W/System.err( 901): at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:348) W/System.err( 901): at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:555) W/System.err( 901): at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:487) W/System.err( 901): at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:465) W/System.err( 901): at me.harrisonlee.test.ssl.MainActivity.connect(MainActivity.java:129) W/System.err( 901): at me.harrisonlee.test.ssl.MainActivity.access$0(MainActivity.java:77) W/System.err( 901): at me.harrisonlee.test.ssl.MainActivity$2.run(MainActivity.java:49) W/System.err( 901): Caused by: java.security.cert.CertificateException: java.security.InvalidAlgorithmParameterException: the trust anchors set is empty W/System.err( 901): at org.apache.harmony.xnet.provider.jsse.TrustManagerImpl.checkServerTrusted(TrustManagerImpl.java:157) W/System.err( 901): at org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl.startHandshake(OpenSSLSocketImpl.java:355) W/System.err( 901): ... 12 more W/System.err( 901): Caused by: java.security.InvalidAlgorithmParameterException: the trust anchors set is empty W/System.err( 901): at java.security.cert.PKIXParameters.checkTrustAnchors(PKIXParameters.java:645) W/System.err( 901): at java.security.cert.PKIXParameters.<init>(PKIXParameters.java:89) W/System.err( 901): at org.apache.harmony.xnet.provider.jsse.TrustManagerImpl.<init>(TrustManagerImpl.java:89) W/System.err( 901): at org.apache.harmony.xnet.provider.jsse.TrustManagerFactoryImpl.engineGetTrustManagers(TrustManagerFactoryImpl.java:134) W/System.err( 901): at javax.net.ssl.TrustManagerFactory.getTrustManagers(TrustManagerFactory.java:226) W/System.err( 901): at org.apache.http.conn.ssl.SSLSocketFactory.createTrustManagers(SSLSocketFactory.java:263) W/System.err( 901): at org.apache.http.conn.ssl.SSLSocketFactory.<init>(SSLSocketFactory.java:190) W/System.err( 901): at org.apache.http.conn.ssl.SSLSocketFactory.<init>(SSLSocketFactory.java:216) W/System.err( 901): at me.harrisonlee.test.ssl.MainActivity.connect(MainActivity.java:107) W/System.err( 901): ... 2 more

• HTTP client - HTTP 405 error "Method not allowed". I send a HTTP Post but for some reason HTTP Get i

  - by Shino88

  Hey I am using apache library. I have created a class which sends a post request to a servlet. I have set up the parameters for the client and i have created a HTTP post object to be sent but for some reason when i excute the request i get a reposnse that says the get method is not supported(which is true cause i have only made a dopost method in my servlet). It seems that a get request is being sent but i dont know why. The post method worked before but i started gettng http error 417 "Expectation Failed" which i fixed by adding paramenters. below is my class with the post method. P.s i am developing for android. public class HTTPrequestHelper { private final ResponseHandler<String> responseHandler; private static final String CLASSTAG = HTTPrequestHelper.class.getSimpleName(); private static final DefaultHttpClient client; static{ HttpParams params = new BasicHttpParams(); params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); params.setParameter(CoreProtocolPNames.HTTP_CONTENT_CHARSET, HTTP.UTF_8); ///params.setParameter(CoreProtocolPNames.USER_AGENT, "Android-x"); params.setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 15000); params.setParameter(CoreConnectionPNames.STALE_CONNECTION_CHECK, false); SchemeRegistry schemeRegistry = new SchemeRegistry(); schemeRegistry.register( new Scheme("http", PlainSocketFactory.getSocketFactory(), 80)); schemeRegistry.register( new Scheme("https", SSLSocketFactory.getSocketFactory(), 443)); ThreadSafeClientConnManager cm = new ThreadSafeClientConnManager(params, schemeRegistry); client = new DefaultHttpClient(cm,params); } public HTTPrequestHelper(ResponseHandler<String> responseHandler) { this.responseHandler = responseHandler; } public void performrequest(String url, String para) { HttpPost post = new HttpPost(url); StringEntity parameters; try { parameters = new StringEntity(para); post.setEntity(parameters); } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } BasicHttpResponse errorResponse = new BasicHttpResponse( new ProtocolVersion("HTTP_ERROR", 1, 1), 500, "ERROR"); try { client.execute(post, this.responseHandler); } catch (Exception e) { errorResponse.setReasonPhrase(e.getMessage()); try { this.responseHandler.handleResponse(errorResponse); } catch (Exception ex) { Log.e( "ouch", "!!! IOException " + ex.getMessage() ); } } } I tried added the allow header to the request but that did not work as well but im not sure if i was doing right. below is the code. client.addRequestInterceptor(new HttpRequestInterceptor() { @Override public void process(HttpRequest request, HttpContext context) throws HttpException, IOException { //request.addHeader("Allow", "POST"); } });

• How to filter a character stream from an application using PowerShell?

  - by Christian

  A powershell question: I want to extract each line in a character stream produced by an application that matches a certain pattern which in pseudo-code would be something like this: PS <a_ps_command> <the_application_command_for_outputting_the_text_stream> | <my_filter > output_file.txt In my case the application is a CM-tool that outputs the change history of a source file and the (psuedo)pattern should be something like: <a couple of numbers><a name><a time stamp><a line of characters> Cheers, Christian

• nhibernate subclass in code

  - by Antonio Nakic Alfirevic

  I would like to set up table-per-classhierarchy inheritance in nhibernate thru code. Everything else is set in XML mapping files except the subclasses. If i up the subclasses in xml all is well, but not from code. This is the code i use - my concrete subclass never gets created:( //the call NHibernate.Cfg.Configuration config = new NHibernate.Cfg.Configuration(); SetSubclass(config, typeof(TAction), typeof(tActionSub1), "Procedure"); //the method public static void SetSubclass(Configuration configuration, Type baseClass, Type subClass, string discriminatorValue) { PersistentClass persBaseClass = configuration.ClassMappings.Where(cm => cm.MappedClass == baseClass).Single(); SingleTableSubclass persSubClass = new SingleTableSubclass(persBaseClass); persSubClass.ClassName = subClass.AssemblyQualifiedName; persSubClass.DiscriminatorValue = discriminatorValue; persSubClass.EntityPersisterClass = typeof(SingleTableEntityPersister); persSubClass.ProxyInterfaceName = (subClass).AssemblyQualifiedName; persSubClass.NodeName = subClass.Name; persSubClass.EntityName = subClass.FullName; persBaseClass.AddSubclass(persSubClass); } the Xml mapping looks like this: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" namespace="Riz.Pcm.Domain.BusinessObjects" assembly="Riz.Pcm.Domain"> <class name="Riz.Pcm.Domain.BusinessObjects.TAction, Riz.Pcm.Domain" table="dbo.tAction" lazy="true"> <id name="Id" column="ID"> <generator class="guid" /> </id> <discriminator type="String" formula="(select jt.Name from TJobType jt where jt.Id=JobTypeId)" insert="true" force="false"/> <many-to-one name="Session" column="SessionID" class="TSession" /> <property name="Order" column="Order1" /> <property name="ProcessStart" column="ProcessStart" /> <property name="ProcessEnd" column="ProcessEnd" /> <property name="Status" column="Status" /> <many-to-one name="JobType" column="JobTypeID" class="TJobType" /> <many-to-one name="Unit" column="UnitID" class="TUnit" /> <bag name="TActionProperties" lazy="true" cascade="all-delete-orphan" inverse="true" > <key column="ActionID"></key> <one-to-many class="TActionProperty"></one-to-many> </bag> <!--<subclass name="Riz.Pcm.Domain.tActionSub" discriminator-value="ZPower"></subclass>--> </class> </hibernate-mapping> What am I doing wrong?

• Ajax, Callback, postback and Sys.WebForms.PageRequestManager.getInstance().add_beginRequest

  - by user338262

  Hi, I have a user control which encapsulates a NumericUpDownExtender. This UserControl implements the interface ICallbackEventHandler, because I want that when a user changes the value of the textbox associated a custom event to be raised in the server. By the other hand each time an async postback is done I shoe a message of loading and disable the whole screen. This works perfect when something is changed in for example an UpdatePanel through this lines of code: Sys.WebForms.PageRequestManager.getInstance().add_beginRequest( function (sender, args) { var modalPopupBehavior = $find('programmaticSavingLoadingModalPopupBehavior'); modalPopupBehavior.show(); } ); The UserControl is placed inside a detailsview which is inside an UpdatePanel in an aspx. When the custom event is raised I want another textbox in the aspx to change its value. So far, When I click on the UpDownExtender, it goes correctly to the server and raises the custom event, and the new value of the textbox is assigned in the server. but it is not changed in the browser. I suspect that the problem is the callback, since I have the same architecture for a UserControl with an AutoCompleteExtender which implement IPostbackEventHandler and it works. Any clues how can I solve this here to make the UpDownNumericExtender user control to work like the AutComplete one? This is the code of the user control and the parent: using System; using System.Web.UI; using System.ComponentModel; using System.Text; namespace Corp.UserControls { [Themeable(true)] public partial class CustomNumericUpDown : CorpNumericUpDown, ICallbackEventHandler { protected void Page_PreRender(object sender, EventArgs e) { if (!Page.IsPostBack) { currentInstanceNumber = CorpAjaxControlToolkitUserControl.getNextInstanceNumber(); } registerControl(this.HFNumericUpDown.ClientID, currentInstanceNumber); string strCallServer = "NumericUpDownCallServer" + currentInstanceNumber.ToString(); // If this function is not written the callback to get the disponibilidadCliente doesn't work if (!Page.ClientScript.IsClientScriptBlockRegistered("ReceiveServerDataNumericUpDown")) { StringBuilder str = new StringBuilder(); str.Append("function ReceiveServerDataNumericUpDown(arg, context) {}").AppendLine(); Page.ClientScript.RegisterClientScriptBlock(typeof(CorpNumericUpDown), "ReceiveServerDataNumericUpDown", str.ToString(), true); } nudeNumericUpDownExtender.BehaviorID = "NumericUpDownEx" + currentInstanceNumber.ToString(); ClientScriptManager cm = Page.ClientScript; String cbReference = cm.GetCallbackEventReference(this, "arg", "ReceiveServerDataNumericUpDown", ""); String callbackScript = "function " + strCallServer + "(arg, context)" + Environment.NewLine + "{" + Environment.NewLine + cbReference + ";" + Environment.NewLine + "}" + Environment.NewLine; cm.RegisterClientScriptBlock(typeof(CustomNumericUpDown), strCallServer, callbackScript, true); base.Page_PreRender(sender,e); } [System.ComponentModel.Browsable(true)] [System.ComponentModel.Bindable(true)] public Int64 Value { get { return (string.IsNullOrEmpty(HFNumericUpDown.Value) ? Int64.Parse("1") : Int64.Parse(HFNumericUpDown.Value)); } set { HFNumericUpDown.Value = value.ToString(); //txtAutoCompleteCliente_AutoCompleteExtender.ContextKey = value.ToString(); // TODO: Change the text of the textbox } } [System.ComponentModel.Browsable(true)] [System.ComponentModel.Bindable(true)] [Description("The text of the numeric up down")] public string Text { get { return txtNumericUpDown.Text; } set { txtNumericUpDown.Text = value; } } public delegate void NumericUpDownChangedHandler(object sender, NumericUpDownChangedArgs e); public event NumericUpDownChangedHandler numericUpDownEvent; [System.ComponentModel.Browsable(true)] [System.ComponentModel.Bindable(true)] [System.ComponentModel.Description("Raised after the number has been increased or decreased")] protected virtual void OnNumericUpDownEvent(object sender, NumericUpDownChangedArgs e) { if (numericUpDownEvent != null) //check to see if anyone has attached to the event numericUpDownEvent(this, e); } #region ICallbackEventHandler Members public string GetCallbackResult() { return "";//throw new NotImplementedException(); } public void RaiseCallbackEvent(string eventArgument) { NumericUpDownChangedArgs nudca = new NumericUpDownChangedArgs(long.Parse(eventArgument)); OnNumericUpDownEvent(this, nudca); } #endregion } /// <summary> /// Class that adds the prestamoList to the event /// </summary> public class NumericUpDownChangedArgs : System.EventArgs { /// <summary> /// The current selected value. /// </summary> public long Value { get; private set; } public NumericUpDownChangedArgs(long value) { Value = value; } } } using System; using System.Collections.Generic; using System.Text; namespace Corp { /// <summary> /// Summary description for CorpAjaxControlToolkitUserControl /// </summary> public class CorpNumericUpDown : CorpAjaxControlToolkitUserControl { private Int16 _currentInstanceNumber; // This variable hold the instanceNumber assignated at first place. public short currentInstanceNumber { get { return _currentInstanceNumber; } set { _currentInstanceNumber = value; } } protected void Page_PreRender(object sender, EventArgs e) { const string strOnChange = "OnChange"; const string strCallServer = "NumericUpDownCallServer"; StringBuilder str = new StringBuilder(); foreach (KeyValuePair<String, Int16> control in controlsToRegister) { str.Append("function ").Append(strOnChange + control.Value).Append("(sender, eventArgs) ").AppendLine(); str.Append("{").AppendLine(); str.Append(" if (sender) {").AppendLine(); str.Append(" var hfield = document.getElementById('").Append(control.Key).Append("');").AppendLine(); str.Append(" if (hfield.value != eventArgs) {").AppendLine(); str.Append(" hfield.value = eventArgs;").AppendLine(); str.Append(" ").Append(strCallServer + control.Value).Append("(eventArgs, eventArgs);").AppendLine(); str.Append(" }").AppendLine(); str.Append(" }").AppendLine(); str.Append("}").AppendLine(); Page.ClientScript.RegisterClientScriptBlock(typeof(CorpNumericUpDown), Guid.NewGuid().ToString(), str.ToString(), true); } str = new StringBuilder(); foreach (KeyValuePair<String, Int16> control in controlsToRegister) { str.Append(" funcsPageLoad[funcsPageLoad.length] = function() { $find('NumericUpDownEx" + control.Value + "').add_currentChanged(").Append(strOnChange + control.Value).Append(");};").AppendLine(); str.Append(" funcsPageUnLoad[funcsPageUnLoad.length] = function() { $find('NumericUpDownEx" + control.Value + "').remove_currentChanged(").Append(strOnChange + control.Value).Append(");};").AppendLine(); } Page.ClientScript.RegisterClientScriptBlock(typeof(CorpNumericUpDown), Guid.NewGuid().ToString(), str.ToString(), true); } } } and to create the loading view I use this: //The beginRequest event is raised before the processing of an asynchronous postback starts and the postback is sent to the server. You can use this event to call custom script to set a request header or to start an animation that notifies the user that the postback is being processed. Sys.WebForms.PageRequestManager.getInstance().add_beginRequest( function (sender, args) { var modalPopupBehavior = $find('programmaticSavingLoadingModalPopupBehavior'); modalPopupBehavior.show(); } ); //The endRequest event is raised after an asynchronous postback is finished and control has been returned to the browser. You can use this event to provide a notification to users or to log errors. Sys.WebForms.PageRequestManager.getInstance().add_endRequest( function (sender, arg) { var modalPopupBehavior = $find('programmaticSavingLoadingModalPopupBehavior'); modalPopupBehavior.hide(); } ); Thanks in advance!

• Android runs OpenGL ES 1.1 or 1.0?

  - by cjserio

  I'm developing a native app for Android and I'm trying to use functions such as glIsEnabled which appear to be only available in OpenGL ES 1.1. Google's docs claim that NDK 1.6R1 supports OpenGL ES v1.1 but the function call fails with "unimplemented Open GL ES API" and if i do a glGetString(GL_VERSION) it returns "OpenGL ES 1.0 CM" as the version. So if 1.1 is available, what do I have to link against to get it or what else do i need to change to get it?

• WhatsApp &amp; Tasker for Android &ndash; Read &amp; Write messages

  - by Shaurya Anand

  So, I finally gave up on all my previous the Microsoft Mobile/Phone OS devices and made my switch to Android this year. I am using my Samsung Galaxy Note GT-N7000 with CyanogenMod 9.1.0 (http://get.cm/get/jenkins/7086/cm-9.1.0-n7000.zip) and ClockworkMod 6.0.1.2 (http://download2.clockworkmod.com/recoveries/recovery-clockwork-6.0.1.2-n7000.zip) since August this year and I am so happy with the performance and the flexibility it offers me. As a software developer by profession, I would expect most of my gadget to be highly customizable and programmable (one time or at intervals) to suit my needs as close as it can. I was introduced to Automation for Android – Tasker (https://play.google.com/store/apps/details?id=net.dinglisch.android.taskerm&hl=en) via reddit (http://www.reddit.com/r/tasker) and the word ‘automation’ was enough for me to dive right into this app. Only automation that I did earlier was switching profiles depending on location on there phones. And now, just imagine a complete set of possibilities that can be automate on the phone or via the phone. I did my research and found a couple of other tools that do the same/as close as what Tasker can do and few of them are even free. There’s one even by Microsoft called on{X} (https://play.google.com/store/apps/details?id=com.microsoft.onx.app&hl=en). Microsoft’s on{X} really caught my eye. You can write code for your phone on the web application by them, deploy it on your phone and even trace the flow all using your PC. Really brilliant, I love the fact that it’s all JavaScript. Here comes the but, it is still very very young and it’s policy of accessing my News Feed on Facebook is not something that I can not digest. On{X} is good, but as I said earlier, the API is not very mature and hence, I gave up on it. I bought Tasker, the best 5,00 € I spent in ages and I want to talk about it in this post. I am still a “noob” while operating this tool, but I tried my shot at automating WhatsApp (https://play.google.com/store/apps/details?id=com.whatsapp&hl=en), a popular messenger for various platform. The requirement for the automation is that, if I send a WhatsApp ‘wru’ message to the phone, it should respond back giving the location and battery level of my phone. It could be useful, if you like to locate your misplaced phone or automatically reply to your partner/friend, honestly, I don’t know what you will use it - through this post, I am just introducing automating WhatsApp using Tasker. Before we begin, the following script only works when your phone is rooted as we will be accessing the WhatsApp database and type some special characters like ‘:’. Let’s follow the code line by line: Profile:         Location request from XYZ. (12) // Name of your profile. Event:         Notification [ Owner Application:WhatsApp Title:* ] // When a new notification comes from WhatsApp, this event is fired. Read the end note, if you face problems with Chrome app after enabling Tasker accessibility. Enter:         A1: Run Shell [ Command:sqlite3 // We will access the WhatsApp database and check if the message comes from designated phone number or not. We mustn’t reply to every message.                 /data/data/com.whatsapp/databases/msgstore.db "SELECT _id, data FROM                  messages WHERE key_from_me='0' AND key_remote_jid LIKE '%XXXXXXXXXXX%' // Replace XXXXXXXXXXX with the phone number of your message sender.                 ORDER BY _id DESC LIMIT 1;" Timeout (Seconds):10 Use Root:On Store // I made a timeout for 10 seconds, if in case WhatsApp is busy accessing the database.                 Result In:%WHATSAPP_CURRREQ ] // Store the read Id and the last message on to the variable %WHATSAPP_CURRREQ         A2: If [ %WHATSAPP_CURRREQ ~R .*[wW][rR][uU].* ] // Check if the pattern of the message is correct and we are all set to send the location.                 A3: If [ %WHATSAPP_CURRREQ !~ %WHATSAPP_LASTREQ ] // Verify that the message is different from the last request. Remember every message has a unique Id.                         A4: Notify [ Title:WhatsApp location request... Text:Sending location // Just a notification that the location message is being prepared.                                 to Krati Gupta... Icon:<icon> Number:0 Permanent:On Priority:3 ] // Make a note it is a permanent notification, we will clear it later.                         A5: Secure Settings [ Configuration:Pattern Lock Disabled // I am disabling the pattern lock, that I use using the plugin Secure Settings.                                 Package:com.intangibleobject.securesettings.plugin Name:Secure // You can download the plugin from here: https://play.google.com/store/apps/details?id=com.intangibleobject.securesettings.plugin&hl=en                                 Settings ]                         A6: Secure Settings [ Configuration:Keyguard Disabled // Disable the keygaurd, it is useful, when your phone is on lock and you want to automate everything, even the typing.                                 Package:com.intangibleobject.securesettings.plugin Name:Secure                                 Settings ]                         A7: Secure Settings [ Configuration:GPS Enabled // Pretty clear, turn on the GPS and get location at A8                                 Package:com.intangibleobject.securesettings.plugin Name:Secure                                 Settings ]                         A8: AutoShortcut [ Configuration:WhatsApp: Some One // I am using AutoShortcut plugin (https://play.google.com/store/apps/details?id=com.joaomgcd.autoshortcut) to start WhatsApp with the indented recipient.                                 Package:com.joaomgcd.autoshortcut Name:AutoShortcut ] // Replace Some One, actually choose it from the plugin, the right recipient.                         A9: Get Location [ Source:Any Timeout (Seconds):30 Continue Task // I am getting the location, timeout is 30 seconds, adjust it accordingly.                                 Immediately:Off Keep Tracking:Off ]                         A10: Secure Settings [ Configuration:Screen Dim // Now, this extension of the plugin Secure Settings, wakes your device so that you can type out the string on the WhatsApp app.                                 5 Seconds Package:com.intangibleobject.securesettings.plugin                                 Name:Secure Settings ]                         A11: Run Shell [ Command:input text // Now, I am using the shell script to type the text to the window, because the ‘:’ while not be typed from the Type task in Tasker.                                 LOCATION:maps.google.com/maps?q=%LOC Timeout (Seconds):0 Use Root:On // And also, this is way faster, but remember you need root for this, not for the other way of typing.                                 Store Result In: ]                         A12: Dpad [ Button:Right Repeat Times:1 ] // Focus the Send button                         A13: Dpad [ Button:Press Repeat Times:1 ] // And press it.                         A14: Dpad [ Button:Left Repeat Times:1 ] // Get back to the typing box.                         A15: Run Shell [ Command:input text LOCATION_ACCURACY:%LOCACC Timeout                                 (Seconds):0 Use Root:On Store Result In: ]                         A16: Dpad [ Button:Right Repeat Times:1 ]                         A17: Dpad [ Button:Press Repeat Times:1 ]                         A18: Dpad [ Button:Left Repeat Times:1 ]                         A19: Run Shell [ Command:input text BATTERY_LEVEL:%BATT% Timeout // I am adding Battery level in my case as well.                                 (Seconds):0 Use Root:On Store Result In: ]                         A20: Dpad [ Button:Right Repeat Times:1 ]                         A21: Dpad [ Button:Press Repeat Times:1 ]                         A22: Variable Set [ Name:%WHATSAPP_LASTREQ To:%WHATSAPP_CURRREQ Do // And now, we say, request is done.                                 Maths:Off Append:Off ]                         A23: Button [ Button:Back ] // I am exiting the WhatsApp nicely and not killing it. If you are the murderer kind, kill it, just know, you don’t have any place in the heaven.                         A24: Button [ Button:Back ]                         A25: Notify Cancel [ Title: Warn Not Exist:Off ] // Remove the permanent notification.                         A26: Notify [ Title:WhatsApp location request Text:Location sent // Make a temporary notification, and say, location is sent.                                 successfully. Icon:<icon> Number:0 Permanent:Off Priority:3 ]                                                         A27: Secure Settings [ Configuration:GPS Disabled // Disable all the horrible things we turned on earlier.                                 Package:com.intangibleobject.securesettings.plugin Name:Secure                                 Settings ]                         A28: Secure Settings [ Configuration:Pattern Lock Enabled                                 Package:com.intangibleobject.securesettings.plugin Name:Secure                                 Settings ]                         A29: Secure Settings [ Configuration:Keyguard Enabled                                 Package:com.intangibleobject.securesettings.plugin Name:Secure                                 Settings ]                 A30: End If         A31: End If Download this Task from here: http://db.tt/9vRmbhyb That’s it in the above small example – you can read/write messages from/to WhatsApp app. I am using n7000-cm9.1-cwr6. Oh yea, and if you are having the Talkback auto enabled for Chrome browser, you need to turn Off the Web scripts to run. Tasker is amazing, I have automated a lot of tasks using this tool. I will share a few none generic ones with you in my coming post here.

• Is there a good dual monitor arm solution for iMac 27" i7s?

  - by Darren Newton

  I currently have an iMac 27" and am considering purchasing another to run in target display mode. My desk space is a little limited. Is there a dual monitor arm solution that can support the weight of two iMac 27" units (30.5 pounds (13.8 kg)) as well as their width (25.6 inches (65.0 cm)) in a side-by-side landscape configuration? I looked at the Ergotron LX Dual Side by Side but the iMacs appear to exceed the width and weight limit this device is rated for. I'm open to alternate solutions to arms, such as a multi-unit desk stand/mount, but a wall mount is not possible for me at this time. Thanks!

• claws-mail suddenly does not recognize my .claws-mail folder

  - by Mala

  Hi I turned my computer on today like any other day, and fired up my email-client claws-mail. However, instead of showing me my inbox, it just pops up the new-account wizard, as though my .claws-mail folder did not exist! I've double-checked that it's there, and that it (seems to) contain everything that it should. I tried running claws-mail from the terminal to see if it returned any useful messages about why it couldn't find my email account, but no dice... For reference, this is CM version 3.7.2 running on Gentoo kernel 2.6.31-gentoo-r6 (x86_64) Any clues as to how to get my beloved inbox/config back? Thanks!

• Vertical alignment problem in textbox in MS Word 2007

  - by Surjya Narayana Padhi

  Hi, I pardon as its not a programming question at all. But if anybody can answer this it will be usefull for me. In MS word 2007 I drew a textbox and entered some text. Then I right clicked on textbox and went to format shape Then went to TextBox tab and reduced the top internal margin to 0.1 cm. But still it seems there is too much space at the top inside the textbox. I am not able to position the text exactly at the vertical middle of textbox. If I choose the auto-rezide option in format Shape, the textBox size is increases automatically but the text remains exactly at vertical and horizontal middle of textbox. but anyhow I need the textbox to be small. This is very minor but annoying problem. Can anybody help?

• Cisco VPN disconnects after 5 seconds with error 422

  - by Marius

  I'm trying to connect to my university's server with VPN using Cisco VPN Client version 5.0.04, but after 5 seconds it disconnects with the error message 422: Lost contact with the secure gateway. Check your connection. From my research on the net it seems this could be because it tries to find my IP, and finds out that this is 127.0.0.1. Then 5 seconds later it discovers that I have a new IP (my actual IP), and it disconnects because I'm not allowed to change IP. Does anyone know how I could fix this, or if there is another reason i get this error? Update I looked through the log, and found this error, which confirms what I thought, except it gets the correct IP first, then changes it to localhost. 87 18:56:53.250 08/24/09 Sev=Warning/3 CM/0xA3100027 Adapter address changed from 149.171.237.25. Current address(es): 127.0.0.1.
