• Track status of Microsoft TTS output to wav file

  - by user325478

  I'm trying to track the status of my applications TTS output to a wav file. When speaking the text (to the speaker) the expected events (StartStream, Word, EndStream) are fired, however, no events are fired when outputing to a wave file. SpVoice vox = new SpVoice(); vox.Word += VoxWord; // Handle word processed event SpFileStream voxStream = new SpFileStream(); voxStream.Open(@"c:\test.wav", SpeechStreamFileMode.SSFMCreateForWrite, false); vox.AudioOutputStream = voxStream; vox.Speak("Hello World. Please track my status!", SpeechVoiceSpeakFlags.SVSFlagsAsync); Is it possible to asynchronously know the status of TTS output to wav?

• Is there an easy way to sign a C++ CLI assembly in VS 2010?

  - by jyoung

  Right now I am setting the Linker/Advanced/KeyFile option. I am getting the "mt.exe : general warning 810100b3: is a strong-name signed assembly and embedding a manifest invalidates the signature. You will need to re-sign this file to make it a valid assembly.". Reading from the web, it sounds like I have to set the delay signing option, download the SDK, and run sn.exe as a post build event. Surely there must be an easier way to do this common operation in VS2010?

• jQuery show submit button on input field click

  - by Pjack

  Hi, I'm trying to have a comment input field that will show the submit button on a dynamically created form when you click on the input field. Similar to how facebook comments work. When you click on the input field the submit button appears and when you click off it disappears. All the comment input id's are comment_1 etc and the submit button id's are submit_1 etc. I've tried this, jQuery("#[id^='comment_']").live('click',function(event){ if(jQuery("#[id^='comment_']").val() == ""){ jQuery("#[id^='submit_']").hide(); } else { jQuery("#[id^='submit_']").show(); } }); And that won't work for some reason. Any suggestion or how it can be accomplished would be great.

• attaching id to a movieclip

  - by Ross

  I have a loop that creates mc from a database for (var i:Number = 0; i < t.length; i++) { var portfolioItem:PortfolioItem = new PortfolioItem(); addChild(portfolioItem); portfolioItem.name = t[i][0]; portfolioItem.addEventListener(MouseEvent.CLICK, getThisName); } public function getThisName(evt:Event) { trace(evt.target.name); } I try and assign t[i][0] which is the table id to the name attribute but I jsut get 'instance4' or instance 14. How can I give these dynamically create mc's a name or custom property? ideally I would like to use a custom property called portfolio.id but would use the name property or another default property if it works.

• Pass Value between MDI Child in WinForm using C#

  - by abhilashca

  I have an MDI Parent, containing a MenuStrip. When I click on one of the Menu, two Child Forms are displayed simultaneoulsy. I have a TextBox and a Send Button on one of my ChildForm. When I type-in something in that TextBox and Click the Send Button, I need to show that value in the TextBox of my Second Child Form. What I had done is, I wrote a Public Function in the Second Child Form and tried to invoke it by creating an object of Second Form, on the Send Button click event. When I put break points, in that Public Function, I find that the control is flowing through that Public function on cliking the Send button. But the passed value is not displayed. And, I know that is not the standard way to do that. Any sample script for help? Thanks.

• Flex chart ItemRollOver behavior

  - by DannyC

  Hi Guys, I'm trying to prevent a default chart item roll over highlight in a Spark column chart. If you look at any of the chart examples on this page , when you roll over any of the chart series items, they turn a darkened shade of their original colour. This is what I want to prevent. So far I have had no luck with using the itemRollOverColor property, as this only allows you to set it to one specific colour for the whole chart (my app has several different coloured series on the chart at once). Also, trying to leverage the itemRollOver event (with preventDefault() etc) hasn't worked either. Does anyone have any idea what I am missing here? Thanks for reading guys

• Change the ApplicationID of a running process from c#

  - by Nestor

  In Windows 7 we have the concept of ApplicationID, which allows (among other things) to group several icons in the task bar. How can I change the ApplicationID of a running process from c#? I'm trying to make my WinForm app's icon group with another application. I've tried using Windows API Code Pack Library, sticking the following code in my Load event... but it didn't work. Suggestions? TaskbarManager.Instance.ApplicationId = "MyAppID"; Process[] p = Process.GetProcessesByName("OtherProcess"); TaskbarManager.Instance.SetApplicationIdForSpecificWindow(p[0].MainWindowHandle, "MyAppID");

• c# - clear surface when resizing

  - by dhh

  Hello, I'm trying to build my own custom control for a windows forms application in C#.Net. Currently I paint some rectangles and other graphic elements using the paint event. When I now resize the app form to fit the desktop size, all elements are repainted (which is exactly the behaviour I need) but the old one's are shown in the background. Here's what I'm doing by now: Pen penDefaultBorder = new Pen(Color.Wheat, 1); int margin = 5; private void CustomControl_Paint(object sender, PaintEventArgs e) { CustomControl calendar = (CustomControl)sender; Graphics graphics = e.Graphics; graphics.Clear(Color.WhiteSmoke); graphics.DrawRectangle(penDefaultBorder, margin, margin, calendar.Width - margin * 2, calendar.Height - margin * 2); //... } Neither the graphics.Clear, nor adding a graphics.FillRectangle(...) will hide the old rectangle from the surface. Ideas? Thank you all.

• Is SELECT INTO able to affect data from its original table during UPDATE

  - by driveby

  Whilst asking this question asp.net scheduling timed events user murph posted some insightful information: Point about this is that its very, very simple - you have an process for exchange that is performing a clearly defined task and you have a high frequency task that is not doing anything particularly complex, its a straightforward query (select from table where sent = false and send at < value) - probably into temporary table so that you can run a single query update after you've done the sends - that you can optimise the index for. You're not trying to queue up a huge pile of event triggers, just one that fires once a minute and processes things that are due. Is it possible to SELECT data from table X INTO table Y and have the UPDATES that are performed on table Y pushed into table X? I guess the alternative would be that the data gets updated in table Y then an update command can be run on table X based on the data in table Y. What would be the advantage of selecting into another table? Thank you,

• Generating Running Sum of Ratings in SQL

  - by Koobz

  I have a rating table. It boils down to: rating_value created +2 april 3rd -5 april 20th So, every time someone gets rated, I track that rating event in the database. I want to generate a rating history/time graph where the rating is the sum of all ratings up to that point in time on a graph. I.E. A person's rating on April 5th might be select sum(rating_value) from ratings where created <= april 5th The only problem with this approach is I have to run this day by day across the interval I'm interested in. Is there some trick to generating a running total using this sort of data? Otherwise, I'm thinking the best approach is to create a denormalized "rating history" table alongside the individual ratings.

• read http header info in ASIHttpRequest asynchronous

  - by user262325

  Hello everyone One of my project is to download several large size files using ASIHTTPRequest in asynchronous mode. I hope to read the http returned header info to get the size of files. I know [request respsonseHeaders] (requestFinished: delegate method ) can do that. I tested and found that requestFinished: is only triggered when it completed the download of a whole single file. But I hope to access the function [request respsonseHeaders] before ASIHTTPRequest starting to download files (just when ASIHTTPRequest got the returned header info). I can not find the triggered event for this. Welcome any comment Thanks interdev

• Simulating a mouse button click in Windows

  - by Ncarlson

  Hi everyone, I'm writing Remote Desktop clone in C++ using QT. So far I'm able to move the mouse cursor around fine. QT has a nice setPos function for that. However, I'm a bit lost as to what API/Library to use for simulating mouse button clicks. One method I'm aware of is to send the WM_(event) to a window using the window's HWND. However, I was hoping there was a more salient method for taking complete control over a mouse. Is there any other way to tell the operating system that the left mouse button has been clicked? Thanks.

• CSS gurus, can I make my absolutely positioned child element force the main parent's height?

  - by alex

  This is kind of hard to explain. I have an absolutely positioned floating secondary content box. It works great in all occurrences. Except, when you submit a form and don't fill out the fields (see here, and push send). The box expands to show the errors, and underneath the footer there is a blank space. The best example I can give is to see it in action (link above). I've played with min-height and it didn't work too good. I'd also like to avoid expanding the footer with code in the event of form errors if I can help it. Should I ditch the absolute positioning? And try with margins? Is there any other way to get it to work?

• Cocoa accessibility API, can I click a window in the background without activating it?

  - by Winawer

  I've been searching forever for a solution to this, so I thought I'd seek out the brainpower of greater minds than mine. I'm developing a Cocoa app that uses the Accessibility API to manipulate another program (it's a hotkey app). The app I'm controlling typically has multiple windows open, with some hidden behind others. What I would like to do, if it's possible, is to send mouse events to windows using the Accessibility API in a way that presses a button in the window without bringing it to the foreground (interact with the window but don't activate it). The reason I'm trying to do this is that sending the mouse event to this other window will force it to the foreground and disrupt the user's interaction with the foremost window. This is possible on Windows - apparently, because apps similar to mine do it there - but I'm getting the feeling that this isn't possible with Cocoa, given the way the window manager works. Am I mistaken?

• Intercept windows open file

  - by HyLian

  Hello, I'm trying to make a small program that could intercept the open process of a file. The purpose is when an user double-click on a file in a given folder, windows would inform to the software, then it process that petition and return windows the data of the file. Maybe there would be another solution like monitoring Open messages and force Windows to wait while the program prepare the contents of the file. One application of this concept, could be to manage desencryption of a file in a transparent way to the user. In this context, the encrypted file would be on the disk and when the user open it ( with double-click on it or with some application such as notepad ), the background process would intercept that open event, desencrypt the file and give the contents of that file to the asking application. It's a little bit strange concept, it could be like "Man In The Middle" network concept, but with files instead of network packets. Thanks for reading.

• CDI @Conversation not propagated with handleNavigation()

  - by Thomas Kernstock

  I have a problem with the propagation of a long runnig conversation when I redirect the view by the handleNavigation() method. Here is my test code: I have a conversationscoped bean and two views: conversationStart.xhtml is called in Browser with URL http://localhost/tests/conversationStart.jsf?paramTestId=ParameterInUrl <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core"> <f:metadata> <f:viewParam name="paramTestId" value="#{conversationTest.fieldTestId}" /> <f:event type="preRenderView" listener="#{conversationTest.preRenderView}" /> </f:metadata> <h:head> <title>Conversation Test</title> </h:head> <h:body> <h:form> <h2>Startpage Test Conversation with Redirect</h2> <h:messages /> <h:outputText value="Testparameter: #{conversationTest.fieldTestId}"/><br /> <h:outputText value="Logged In: #{conversationTest.loggedIn}"/><br /> <h:outputText value="Conversation ID: #{conversationTest.convID}"/><br /> <h:outputText value="Conversation Transient: #{conversationTest.convTransient}"/><br /> <h:commandButton action="#{conversationTest.startLogin}" value="Login ->" rendered="#{conversationTest.loggedIn==false}" /><br /> <h:commandLink action="/tests/conversationLogin.xhtml?faces-redirect=true" value="Login ->" rendered="#{conversationTest.loggedIn==false}" /><br /> </h:form> <h:link outcome="/tests/conversationLogin.xhtml" value="Login Link" rendered="#{conversationTest.loggedIn==false}"> <f:param name="cid" value="#{conversationTest.convID}"></f:param> </h:link> </h:body> </html> The Parameter is written to the beanfield and displayed in the view correctly. There are 3 different possibilites to navigate to the next View. All 3 work fine. The beanfield shows up the next view (conversationLogin.xhtml) too: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core"> <h:head> <title>Conversation Test</title> </h:head> <h:body> <h:form> <h2>Loginpage Test Conversation with Redirect</h2> <h:messages /> <h:outputText value="Testparameter: #{conversationTest.fieldTestId}"/><br /> <h:outputText value="Logged In: #{conversationTest.loggedIn}"/><br /> <h:outputText value="Conversation ID: #{conversationTest.convID}"/><br /> <h:outputText value="Conversation Transient: #{conversationTest.convTransient}"/><br /> <h:commandButton action="#{conversationTest.login}" value="Login And Return" /><br /> </h:form> </h:body> </html> When I return to the Startpage by clicking the button the conversation bean still contains all values. So everything is fine. Here is the bean: package test; import java.io.Serializable; import javax.annotation.PostConstruct; import javax.enterprise.context.Conversation; import javax.enterprise.context.ConversationScoped; import javax.faces.event.ComponentSystemEvent; import javax.inject.Inject; import javax.inject.Named; @Named @ConversationScoped public class ConversationTest implements Serializable{ private static final long serialVersionUID = 1L; final String CONVERSATION_NAME="longRun"; @Inject Conversation conversation; private boolean loggedIn; private String fieldTestId; @PostConstruct public void init(){ if(conversation.isTransient()){ conversation.begin(CONVERSATION_NAME); System.out.println("New Conversation started"); } loggedIn=false; } public String getConvID(){ return conversation.getId(); } public boolean isConvTransient(){ return conversation.isTransient(); } public boolean getLoggedIn(){ return loggedIn; } public String startLogin(){ return "/tests/conversationLogin.xhtml?faces-redirect=true"; } public String login(){ loggedIn=true; return "/tests/conversationStart.xhtml?faces-redirect=true"; } public void preRenderView(ComponentSystemEvent ev) { // if(!loggedIn){ // System.out.println("Will redirect to Login"); // FacesContext ctx = FacesContext.getCurrentInstance(); // ctx.getApplication().getNavigationHandler().handleNavigation(ctx, null, "/tests/conversationLogin.xhtml?faces-redirect=true"); // ctx.renderResponse(); // } } public void setFieldTestId(String fieldTestId) { System.out.println("fieldTestID was set to: "+fieldTestId); this.fieldTestId = fieldTestId; } public String getFieldTestId() { return fieldTestId; } } Now comes the problem !! As soon as I try to redirect the page in the preRenderView method of the bean (just uncomment the code in the method), using handleNavigation() the bean is created again in the next view instead of using the allready created instance. Although the cid parameter is propagated to the next view ! Has anybody an idea what's wrong ? best regards Thomas

• Hiding ListViewItem based on a filter

  - by fonix232

  I want to hide some items based on a text filter in a ListView (WinForms). Basically the listview loads the items from a text file, and I don't want it to be read and/or written when the user searches the list. The search is done in a combobox's KeyDown event, but there is no "Visible" property of the ListViewItem. Is there any easy way to do this, WITHOUT re-reading the file? (as it is an XML file, and it could even contain thousands of items, it would be hard to search efficiently and even let the user use the application, as the search would take for minutes (mostly with the loading)).

• PHP code not working on IE

  - by Michael Frey

  I have a website with a flag. If it is clicked, the language of the website changes. Here is the code displaying the flag, which is a form with post event: <?php $pagename = $_SERVER['REQUEST_URI']; echo '<form action="'.$pagename.'" method="post"> <input name="formlanguage" type="image" '; if ($_SESSION['lang'] == 0) { echo 'alt="English" src="images/en.png" value="1" '; } else { echo 'alt="Deutsch" src="images/de.png" value="0" '; } echo '/></form>'; ?> Here is the response to that, and this part always fails on IE: if (isset($_POST['formlanguage'])) { $_SESSION['lang']=$_POST['formlanguage']; } I can not figure out why it works on Chrome but not IE. I assume that it might be a setting of IE. But what could that be?

• How to store local variables in jQuery click functions?

  - by Geuis

  I'm trying to figure out how to store external variable values in the functions created during jQuery's click() event. Here's a sample of the code I'm working with now. for(var i=0; i<3; i++){ $('#tmpid'+i).click(function(){ var gid = i; alert(gid); }); } <div id="tmpid0">1al</div> <div id="tmpid1">asd</div> <div id="tmpid2">qwe</div> So what's happening is that the events are attaching properly, but the value of 'gid' is always the last incremented value of 'i'. I'm not sure how to setup the private variable in this situation.

• Form Inheritance in Visual Studios designer implementations

  - by CooPzZ

  I'm in the process of Moving a project from Visual Studio 2003 to 2005 and have just seen the The event Click is read-only and cannot be changed when using inherited forms regardless of the Modifier on the Base Forms Controls will make all the Controls from the Base Readonly in the designer (Though in 2003 it didn't work this way). I found this post metioning that this functionality has been temporarily" disabled http://social.msdn.microsoft.com/Forums/en-US/winformsdesigner/thread/c25cec28-67a5-4e30-bb2d-9f8dbd41eb3a Can anyone confirm whether this feature is used anymore? or how to program around it to be able to use the Base Control Events and still have a designer? This is one way I've found but quite painfull when it used to do the plumbing for you. even just hiding one of the controls you have manually do now. Public Class BFormChild Friend Overrides Sub cmdApply_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdApply_Click(sender, e) End Sub Friend Overrides Sub cmdCancel_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdCancel_Click(sender, e) End Sub Friend Overrides Sub cmdOk_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdOk_Click(sender, e) End Sub End Class
