  • Method works on Emulator but no on Microsoft Surface unit?

    - by Roflcoptr
    I have the following code. The StartRecord method trows an error on the Microsoft Surface Unit. But when I'm testing it on the emulator, it all works great. Any hints how 1) to find the exception that is thrown on the Microsoft Surface Unit? 2) to find the error in the code? any assumptions? private void StartRecord(object sender, ContactEventArgs e) { isRecording = true; StartButton.IsEnabled = false; recordTimer = new Timer(10); recordTimer.Elapsed += new ElapsedEventHandler(recordTimer_Elapsed); PlaybackRoot.Visibility = System.Windows.Visibility.Collapsed; EllapsedRecord.Visibility = System.Windows.Visibility.Visible; InputLevel.Visibility = System.Windows.Visibility.Visible; long time = DateTime.Now.Ticks; String fileName = Convert.ToString(time) + ".wav"; Console.WriteLine(fileName); startTime = DateTime.UtcNow; recordTimer.Start(); record = new AudioRecording(fileName); record.getSampleAggregator().MaximumCalculated += new EventHandler<MaxSampleEventArgs>(AudioControl_MaximumCalculated); record.start(); }

  • autotools: no rule to make target all

    - by Raffo
    I'm trying to port an application I'm developing to autotools. I'm not an expert in writing makefiles and it's a requisite for me to be able to use autotools. In particular, the structure of the project is the following: .. ../src/Main.cpp ../src/foo/ ../src/foo/x.cpp ../src/foo/y.cpp ../src/foo/A/k.cpp ../src/foo/A/Makefile.am ../src/foo/Makefile.am ../src/bar/ ../src/bar/z.cpp ../src/bar/w.cpp ../src/bar/Makefile.am ../inc/foo/ ../inc/bar/ ../inc/foo/A ../configure.in ../Makefile.am The root folder of the project contains a "src" folder containing the main of the program AND a number of subfolders containing the other sources of the program. The root of the project also contains an "inc" folder containing the .h files that are nothing more than the definitions of the classes in "src", thus "inc" reflects the structure of "src". I have written the following configure.in in the root: AC_INIT([PNAME], [1.0]) AC_CONFIG_SRCDIR([src/Main.cpp]) AC_CONFIG_HEADER([config.h]) AC_PROG_CXX AC_PROG_CC AC_PROG_LIBTOOL AM_INIT_AUTOMAKE([foreign]) AC_CONFIG_FILES([Makefile src/Makefile src/foo/Makefile src/foo/A/Makefile src/bar/Makefile]) AC_OUTPUT And the following is ../Makefile.am SUBDIRS = src and then in ../src where the main of the project is contained: bin_PROGRAMS = pname gsi_SOURCES = Main.cpp AM_CPPFLAGS = -I../../inc/foo\ -I../../inc/foo/A \ -I../../inc/bar/ pname_LDADD= foo/libfoo.a bar/libbar.a SUBDIRS = foo bar and in ../src/foo noinst_LIBRARIES = libfoo.a libfoo_a_SOURCES = \ x.cpp \ y.cpp AM_CPPFLAGS = \ -I../../inc/foo \ -I../../inc/foo/A \ -I../../inc/bar And the analogous in src/bar. The problem is that after calling automake and autoconf, when calling "make" the compilation fails. In particular, the program enters the directory src, then foo and creates libfoo.a, but the same fail for libbar.a, with the following error: Making all in bar make[3]: Entering directory `/user/Raffo/project/src/bar' make[3]: *** No rule to make target `all'. Stop. I have read the autotools documentation, but I'm not able to find a similar example to the one I am working on. Unfortunately I can't change the directory structure as this is a fixed requisite of the project I'm working on. I don't know if you can help me or give me any hint, but maybe you can guess the error or give me a link to a similar structured example. Thank you.

  • wrapping user controls in a transaction

    - by Hans Gruber
    I'm working on heavily dynamic and configurable CMS system. Therefore, many pages are composed of a dynamically loaded set of user controls. To enable loose coupling between containers (pages) and children (user controls), all user controls are responsible for their own persistence. Each User Control is wired up to its data/service layer dependencies via IoC. They also implement an IPersistable interface, which allows the container .aspx page to issue a Save command to its children without knowledge of the number or exact nature of these user controls. Note: what follows is only pseudo-code: public class MyUserControl : IPersistable, IValidatable { public void Save() { throw new NotImplementedException(); } public bool IsValid() { throw new NotImplementedException(); } } public partial class MyPage { public void btnSave_Click(object sender, EventArgs e) { foreach (IValidatable control in Controls) { if (!control.IsValid) { throw new Exception("error"); } } foreach (IPersistable control in Controls) { if (!control.Save) { throw new Exception("error"); } } } } I'm thinking of using declarative transactions from the System.EnterpriseService namespace to wrap the btnSave_Click in a transaction in case of an exception, but I'm not sure how this might be achieved or any pitfalls to such an approach.

  • My Android XML files can't find ActionBarSherlock themes

    - by MalcolmMcC
    I'm trying to develop an app with ActionBarSherlock and everything works except the theming. Specifically, I can import com.actionbarsherlock.app.*, extend SherlockActivity, but I always have this error in my manifest: Error: No resource found that matches the given name (at 'theme' with value '@style/Theme.Sherlock'). I know there have been plenty of questions asked about this, but they have not worked for me. I have tried refreshing the workspace cleaning all of my projects putting the line in both the <activity> and the <application> setting my targetSdkVersion and minSdkVersion to various values, in both my manifest and ABS's and I've tried the following variations, and probably others: android:theme="@style/Theme.Sherlock" android:theme="@android:style/Theme.Sherlock" theme="@style/Theme.Sherlock" theme="@android:style/Theme.Sherlock" theme="@theme/Theme.Sherlock" theme="@android:theme/Theme.Sherlock" It's worth noting that the autocomplete after I typed "@style/" was showing nothing, so I tried making my own style in styles.xml and then that showed up but still nothing from ActionBarSherlock. Also, in styles.xml, I tried to make my own theme to extend Theme.Sherlock, and @style/Theme.Sherlock was not found there either when I tried to add it as a parent. I tried loading the samples but got a JAR Mismatch. My conclusion is that somehow my xml files are unable to access the ABS library, but I'm at a loss as to how to fix it. Any help hugely appreciated.

  • python can't start a new thread

    - by Giorgos Komnino
    I am building a multi threading application. I have setup a threadPool. [ A Queue of size N and N Workers that get data from the queue] When all tasks are done I use tasks.join() where tasks is the queue . The application seems to run smoothly until suddently at some point (after 20 minutes in example) it terminates with the error thread.error: can't start new thread Any ideas? Edit: The threads are daemon Threads and the code is like: while True: t0 = time.time() keyword_statuses = DBSession.query(KeywordStatus).filter(KeywordStatus.status==0).options(joinedload(KeywordStatus.keyword)).with_lockmode("update").limit(100) if keyword_statuses.count() == 0: DBSession.commit() break for kw_status in keyword_statuses: kw_status.status = 1 DBSession.commit() t0 = time.time() w = SWorker(threads_no=32, network_server='http://192.168.1.242:8180/', keywords=keyword_statuses, cities=cities, saver=MySqlRawSave(DBSession), loglevel='debug') w.work() print 'finished' When the daemon threads are killed? When the application finishes or when the work() finishes?

  • Cannot call DLL import entry in C# from C++ project. EntryPointNotFoundException

    - by kriau
    I'm trying to call from C# a function in a custom DLL written in C++. However I'm getting the warning during code analysis and the error at runtime: Warning: CA1400 : Microsoft.Interoperability : Correct the declaration of 'SafeNativeMethods.SetHook()' so that it correctly points to an existing entry point in 'wi.dll'. The unmanaged entry point name currently linked to is SetHook. Error: System.EntryPointNotFoundException was unhandled. Unable to find an entry point named 'SetHook' in DLL 'wi.dll'. Both projects wi.dll and C# exe has been compiled in to the same DEBUG folder, both files reside here. There is only one file with the name wi.dll in the whole file system. C++ function definition looks like: #define WI_API __declspec(dllexport) bool WI_API SetHook(); I can see exported function using Dependency Walker: as decorated: bool SetHook(void) as undecorated: ?SetHook@@YA_NXZ C# DLL import looks like (I've defined these lines using CLRInsideOut from MSDN magazine): [DllImport("wi.dll", EntryPoint = "SetHook", CallingConvention = CallingConvention.Cdecl)] [return: MarshalAsAttribute(UnmanagedType.I1)] internal static extern bool SetHook(); I've tried without EntryPoint and CallingConvention definitions as well. Both projects are 32-bits, I'm using W7 64 bits, VS 2010 RC. I believe that I simply have overlooked something.... Thanks in advance.

    In my website project. I need to rename or remove some folder by code.

    I am developing an application in MVC 3. I installed this provider via Nuget . Basically, it allows to use any part of memberships, rules and profiles with a .sdf (compact) database. I need the "Web Site Administration Tool" use this provider. But I can not use it. Already checked the web.config and everything is ok. When I open the "Web Site Administration Tool" on the Security I click test (any provider) and the error happens. The following images. Error when clicking test "Could not establish a connection to the database. If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider."

  • DataReader already open when using LINQ

    - by Jamie Dixon
    I've got a static class containing a static field which makes reference to a wrapper object of a DataContext. The DataContext is basically generated by Visual Studio when we created a dbml file & contains methods for each of the stored procedures we have in the DB. Our class basically has a bunch of static methods that fire off each of these stored proc methods & then returns an array based on a LINQ query. Example: public static TwoFieldBarData[] GetAgesReportData(string pct) { return DataContext .BreakdownOfUsersByAge(Constants.USER_MEDICAL_PROFILE_KEY, pct) .Select(x => new TwoFieldBarData(x.DisplayName, x.LeftValue, x.RightValue, x.TotalCount)) .ToArray(); } Every now and then, we get the following error: There is already an open DataReader associated with this Command which must be closed firs This is happening intermittently and I'm curious as to what is going on. My guess is that when there's some lag between one method executing and the next one firing, it's locking up the DataContext and throwing the error. Could this be a case for wrapping each of the DataContext LINQ calls in a lock(){} to obtain exclusivity to that type and ensure other requests are queued?

  • Jquery and PHP rating function problem

    - by Sergio
    I know that I was already posted similar question but I just can't find the answer and figure it out how to solve this problem. I'm trying to customize Jquery Star Rating plugin (link text) but I do not know what to do to show the message based on response of PHP script. Jquery script successfully send rating data to PHP scripts that query the database and based on that echo message of proper or improper rating. What should I add to an existing JS code so I can get echo from PHP and base on that write a message on some DIV beside rating star? Jquery: $('#gal').rating('gl.php?gal_no=<?=$gal_no;?>&id=<?=$id;?>', {maxvalue:10,increment:.5, curvalue: <?=$cur;?>}); Simplified PHP code: $br=mysql_query("SELECT count(gal) as total FROM ...") if ... { echo '0'; } else echo '1'; } Jquery code successfully transmitted data to PHP script and when the PHP done with checking data echo the result ('1' or '0'). How can I get this PHP result back to Jquery and based on them write a message? Something like: if(data=="1") { $("#error").show("fast").html('not correct').css({'background-color':'#F5F5F5','border-color' : '#F69'}); }else{ $("#error").show("fast").html('correct').css({'background-color' : '#FFF','border-color' : '#3b5998'}); } If someone has an idea...I would appreciate it.

  • Is there a way to validates_presence_of only one time? (to skip that validation once the user's been

    - by GoodGets
    So, I'd like for a user to see an error message if he submits a comment and the :name is blank (typical error message, don't need help with that). However, I'd then like to allow the user to skip that validation once he's been notified that "we like all comments to have a name." So, he submits the comment once, sees the notification, then can submit the form again unchanged if he really doesn't want to add a name, and the validates_presences_of :name is skipped. But, I'm not sure how to go about doing this. I thought about checking to see where the request is coming from, but after a create, errors are handed off to the "new" action, which is the same as actual "new" comments. I then thought about checking to see if flash[errors] were present, but that won't work because there are other validations a comment has to pass. Finally, I thought about trying a validates_presences_of :name, :unless = :notified but wasn't sure how to define notified. I honestly hate asking such an open ended question, but wasn't sure where to get started. So, is there a way to just check a certain validation once?

  • UIAlertView choice causing resignFirstResponder to fail

    - by Chazbot
    Hi everyone. I'm having a similar issue to Anthony Chan's question, and after trying every suggested solution, I'm still stuck. Somehow, only after interacting with my UIAlertView, I'm unable to dismiss the keyboard in another view of my app. It's as though the Alert is breaking my UITextField's ability to resignFirstResponder. Below I instantiate my UIAlertView, which then calls its didDismissWIthButtonIndex method. Then, I call the showInfo method, which loads another UIViewController. UIAlertView *emailFailAlert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"error message text." delegate:self cancelButtonTitle:@"Not now" otherButtonTitles:@"Settings", nil]; [emailFailAlert setTag:2]; [emailFailAlert show]; [emailFailAlert release]; Once the 'Settings' option is pressed, I'm calling this method: - (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex { if ([alertView tag] == 2) { if (buttonIndex == 1){ [self showInfo:nil]; } } } My showInfo method loads the other ViewController, via the code below: - (IBAction)showInfo:(id)sender { FlipsideViewController *fscontroller = [[FlipsideViewController alloc] initWithNibName:@"FlipsideView" bundle:nil]; fscontroller.delegate = self; fscontroller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:fscontroller animated:YES]; [fscontroller release]; } Upon clicking any textField in this Flipside VC, I'm unable to dismiss the keyboard as I normally can with - (BOOL)textFieldShouldReturn:(UITextField *)textField, and [textField resignFirstResponder]. I've omitted this code bc this question is getting long, but I'm happy to post if necessary. The interesting part is that if I comment out the [self showInfo:nil] call made when the button is clicked and call it by clicking a test button (outside the alertView didDismissWithButtonIndex: method), everything works fine. Any idea what's happening here? Thanks in advance!

But, problem is when I try this code from my work place, it does not work. Shows error: "unable to connect to the remote server" From a different machine in the same network: "A socket operation was attempted to an unreachable network 209.xxx.xx.52:25" I checked with our network admin, and he assured me that all the mail ports are open [25,110, and other ports for gmail]. Then, I logged in with administrative privilege, there was a little improvement, it did not show any error, but the actual email was never received. Please note that, the code was tested from development environment, visual studio 2005 and 2008. Any suggestion will be much appreciated.

  • How to call a javascript function from one frame to another in Chrome/Webkit

    - by bambax
    I have developped an application that has a list of items in one frame; when one clicks on an item it does something in another frame (loads an image). This used to work fine in all browsers, including Chrome 3; now it still works fine in FF but in recent versions of Chrome (I believe since 4) it throws this error: Unsafe JavaScript attempt to access frame with URL (...) from frame with URL (...). Domains, protocols and ports must match. This is obviously a security "feature" but is it possible to get around it? Here is a simple test: index.html: <html> <frameset> <frame src="left.html" name="left"/> <frame src="right.html" name="right"/> </frameset> </html> left.html: <html> <body> <a href="javascript:parent.right.test('hello');">click me</a> </body> </html> right.html: <html> <body> <script> function test(msg) { alert(msg); } </script> </body> </html> The above works in FF 3.6 and Chrome 3 but in Chrome 5 it throws the above error...

  • Module not found

    - by TMP
    Hi There! I've been working on this one quite a bit and haven't gotten any closer to a solution. I juut dug up my old copy of the WindowsHookLib again - It's available with source at http://www.codeproject.com/KB/DLL/WindowsHookLib.aspx. This library allows Global Windows Mouse/Keyboard/Clipboard Hooks, which is very useful. I'm trying to use the Mouse Hook in here to Capture Mouse-Motion (I could use a Timer that always polls Cursor.Position, but I plan on using more features of WindowsHookLib later). Code as follows: MouseHook mh = new MouseHook(); mh.InstallHook(); mh.MouseMove += new EventHandler<WindowsHookLib.MouseEventArgs>(mh_MouseMove); But on the call to InstallHook(), I get an Exception: "The specified Module could not be found". Strange. Searching, I found that someone thought this occurs because a DLL is not in a place included in the Windows PATH variable, and because placing it in system32 didn't help I went the whole hog and translated the thing to C# for inclusion directly in my project (I was curious how it works). However the error was obstinately persistent, so I dug a bit on this, and found the Code in the Library that is responsible: In InstallHook(), we have IntPtr hinstDLL = Marshal.GetHINSTANCE(Assembly.GetExecutingAssembly().GetModules()[0]); this._hMouseHook = UnsafeNativeMethods.SetWindowsHookEx(14, this._mouseProc, hinstDLL, 0); if (this._hMouseHook == IntPtr.Zero) { throw new MouseHookException(new Win32Exception(Marshal.GetLastWin32Error()).Message); } And this (after modification and recompile) tells me that what I'm really getting is a Windows error "ERROR_MOD_NOT_FOUND"! Now, Here I'm stumped. Didn't I just compile the Hook Library directly into my project? (UnsafeMethods.SetWindowsHookEx is just a DllImported Method from user32) Any Answers, or Prods in the right direction, or any hints, pointers or similar are very much appreciated!

  • Why does GCC need extra declarations in templates when VS does not?

Yet when I compile under GCC 4.1 with lines A and B commented, I get these errors: In member function ‘void TemplateDerived::foo()’: error: ‘t’ was not declared in this scope error: there are no arguments to ‘get’ that depend on a template parameter, so a declaration of ‘get’ must be available Why would one compiler require lines A and B while the other doesn't? Is there a way to simplify this? In other words, if derived classes use 20 things from the base class, I have to put 20 lines of declarations for every class deriving from Base! Is there a way around this that doesn't require so many declarations?

  • Using LINQ on observable with GroupBy and Sum aggregate

    - by Mark Oates
    I have the following block of code which works fine; var boughtItemsToday = (from DBControl.MoneySpent bought in BoughtItemDB.BoughtItems select bought); BoughtItems = new ObservableCollection<DBControl.MoneySpent>(boughtItemsToday); It returns data from my MoneySpent table which includes ItemCategory, ItemAmount, ItemDateTime. I want to change it to group by ItemCategory and ItemAmount so I can see where I am spending most of my money, so I created a GroupBy query, and ended up with this; var finalQuery = boughtItemsToday.AsQueryable().GroupBy(category => category.ItemCategory); BoughtItems = new ObservableCollection<DBControl.MoneySpent>(finalQuery); Which gives me 2 errors; Error 1 The best overloaded method match for 'System.Collections.ObjectModel.ObservableCollection.ObservableCollection(System.Collections.Generic.List)' has some invalid arguments Error 2 Argument 1: cannot convert from 'System.Linq.IQueryable' to 'System.Collections.Generic.List' And this is where I'm stuck! How can I use the GroupBy and Sum aggregate function to get a list of my categories and the associated spend in 1 LINQ query?! Any help/suggestions gratefully received. Mark

  • Why is my .htaccess file redirecting to full server path instead of relative path?

    - by death.au
    I've never had a problem with cakePHP before, but something's odd about this server and is causing the redirects in the .htaccess files to behave oddly. CakePHP uses mod_rewrite in .htaccess files to redirect requests to its own webroot folder. The problem is that the redirects are listing the wrong path and causing a 404 error. My CakePHP application, which is stored in the listings directory, has a .htaccess file as follows: <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^$ app/webroot/ [R=301,L] RewriteRule (.*) app/webroot/$1 [R=301,L] </IfModule> (*note that the R=301 causes an external redirect so we can see what is going on from our end. It should really omit this flag and do the redirect internally, transparent to end-users) This is supposed to redirect any request from http://hostname.com/~username/listings/ to http://hostname.com/~username/listings/app/webroot/ However, rather than simply adding “app/webroot/” to the end as it is supposed to, it is adding the full server path ( /home/username/public_html/listings/app/webroot/ ) resulting in the final URL http://hostname.com/home/username/public_html/listings/app/webroot/ which is obviously incorrect and triggers a 404 error. The hosting is on a shared hosting account, so that limits what I can do with the settings. I've never seen this happen before, and I'm thinking it's something wrong from the hosting side of things, but if anyone has some helpful suggestions then I can put them to the hosting company as well.

  • Problems with rails and saving to the database.

    - by Grantismo
    I've been having some difficulty in understanding the source of a problem. Below is a listing of the model classes. Essentially the goal is to have the ability to add sentences to the end of the story, or to add stories to an existing sentence_block. Right now, I'm only attempting to allow users to add sentences, and automatically create a new sentence_block for the new sentence. class Story < ActiveRecord::Base has_many :sentence_blocks, :dependent => :destroy has_many :sentences, :through => :sentence_blocks accepts_nested_attributes_for :sentence_blocks end class SentenceBlock < ActiveRecord::Base belongs_to :story has_many :sentences, :dependent => :destroy end class Sentence < ActiveRecord::Base belongs_to :sentence_block def story @sentence_block = SentenceBlock.find(self.sentence_block_id) Story.find(@sentence_block.story_id) end end The problem is occurring when using the show method of the Story. The Story method is as follows, and the associated show method for a sentence is also included. Sentence.show def show @sentence = Sentence.find(params[:id]) respond_to do |format| format.html {redirect_to(@sentence.story)} format.xml { render :xml => @sentence } end end Story.show def show @story = Story.find(params[:id]) @sentence_block = @story.sentence_blocks.build @new_sentence = @sentence_block.sentences.build(params[:sentence]) respond_to do |format| if @new_sentence.content != nil and @new_sentence.sentence_block_id != nil and @sentence_block.save and @new_sentence.save flash[:notice] = 'Sentence was successfully added.' format.html # new.html.erb format.xml { render :xml => @story } else @sentence_block.destroy format.html format.xml { render :xml => @story } end end end I'm getting a "couldn't find Sentence_block without and id" error. So I'm assuming that for some reason the sentence_block isn't getting saved to the database. Can anyone help me with my understanding of the behavior and why I'm getting the error? I'm trying to ensure that every time the view depicts show for a story, an unnecessary sentence_block and sentence isn't created, unless someone submits the form, I'm not really sure how to accomplish this. Any help would be appreciated.

  • How to create an array of buttons in C++

    - by mangoman13
    Hi, I'm using C++ in VS2005 and have an 8x8 grid of buttons on a form. I want to have these buttons in an array, so when I click on any of them it will open the same event handler (I think that is what they are called), but I will know the index of which one was clicked on. I know how to do this in VB and C#, but I can't seem to figure it out with C++ Right now I have all my buttons labelled by their location, i.e. b00, b10, b21, etc. So I think what I am looking for is a way to do something like this: Button b[8][8]; //this causes me errors (error C2728: 'System::Windows::Forms::Button' : a native array cannot contain this managed type) and (error C2227: left of '->{ctor}' must point to class/struct/union/generic type) void Assignment(){ b[0][0] = b00; b[1][0] = b10; ... } and then in form1.h: private: System::Void b_Click(System::Object^ sender, System::EventArgs^ e) { //somehow read the coordinates into variables x and y //do something based on these values } Any help would be appreciated. Also let me know if I am going in the complete wrong direction with this. Thanks!

  • C# async callback on disposed form

    - by Rodney Burton
    Quick question: One of my forms in my winform app (c#) makes an async call to a WCF service to get some data. If the form happens to close before the callback happens, it crashes with an error about accessing a disposed object. What's the correct way to check/handle this situation? The error happens on the Invoke call to the method to update my form, but I can't drill down to the inner exception because it says the code has been optimized. The Code: public void RequestUserPhoto(int userID) { WCF.Service.BeginGetUserPhoto(userID, new AsyncCallback(GetUserPhotoCB), userID); } public void GetUserPhotoCB(IAsyncResult result) { var photo = WCF.Service.EndGetUserPhoto(result); int userID = (int)result.AsyncState; UpdateUserPhoto(userID, photo); } public delegate void UpdateUserPhotoDelegate(int userID, Binary photo); public void UpdateUserPhoto(int userID, Binary photo) { if (InvokeRequired) { var d = new UpdateUserPhotoDelegate(UpdateUserPhoto); Invoke(d, new object[] { userID, photo }); } else { if (photo != null) { var ms = new MemoryStream(photo.ToArray()); var bmp = new System.Drawing.Bitmap(ms); if (userID == theForm.AuthUserID) { pbMyPhoto.BackgroundImage = bmp; } else { pbPhoto.BackgroundImage = bmp; } } } }
