  • jQuery's blur() and selector problem

    - by matthewayinde
    I'm trying to create a new div each time a text field contained in the last div loses focus, but a new div is added only when the text field in the first div loses focus (instead of the last)... Please I need help urgently. Thanks a lot. Here's my code: $(function() { $(':text:last').blur(function() { $('<div class="line"><span>data: </span><input type="text"/></div>') .appendTo($('#lineStack')); }); }); HTML: <div id="lineStack"> <div class="line"> <span>data: </span><input type="text" /> </div> </div>

  • Training speech recognition software

    - by wyatt
    A little left field, but I'm trying to train a speech recognition program and the guidelines suggest that I attempt to speak clearly but naturally. I notice, however, that when one speaks naturally each word tends to drift into the next, resulting in a rather ambiguous boundary between the words. One the one hand, speaking in a more stilted manner would seem to aid the computer in recognising the phonemes, but on the other it would tend to make it less likely to understand more natural speech. Anyone knowledgeable in the field out there who can suggest which of the two approaches is more effective? Thanks

  • MS Access MSChart.Graph.8 not printing

    - by Tanj
    Software: Microsoft Access 2007 SP2 Database File Version: Access 2000 I have an access program that I inherited from a previous employee. It uses forms for reports and since I don't have much experience in access I have continued to do this. I have created a copy of the program for another project and modified it to suit. I am having trouble getting more then one chart to print. All the charts display in form view, they all have the same properties (excepting data, position, etc.) For some reason they are not printing. They don't even show up in the print preview. I am thinking it must be something with the graphs themselves as they sometimes lose all information. I have to open the graphs in edit mode and change the data source from column to row and back again so that it gets redrawn. (Refresh doesn't fix it) So right now I don't even have a clue as to where to look so ideas are welcome. Edit #1 It seems to be a problem with linking to an unbound form. Subform Field Linker: Can't build a link between unbound forms. The query for the main form is SELECT tTest.ixTest, tMotorTypes.ixMotorType, tMotorTypes.asMotorType, tMotorTypes.fDeprecated, tTestType.asTest, tTest.asSerialNum, tTest.asOrderNum, tTest.asFrameNum, tTest.asRotorNum, tTest.asOperator, tTest.iStation, tTest.dtTestDate, tTest.ixTestType FROM tMotorTypes INNER JOIN (tTestType INNER JOIN tTest ON tTestType.ixTestType=tTest.ixTestType) ON tMotorTypes.ixMotorType=tTest.ixMotorType; The query for the chart is: SELECT qGraphRSTTemperatures.Frequency, qGraphRSTTemperatures.[Drive End], qGraphRSTTemperatures.[Non Drive End], qGraphRSTTemperatures.[Air In], qGraphRSTTemperatures.Core FROM qGraphRSTTemperatures ORDER BY qGraphRSTTemperatures.ixTemperature; Query qGraphRSTTemperatures: SELECT tElectricalData.dblFrequency AS Frequency, tTemperatures.dblDrvEnd AS [Drive End], tTemperatures.dblNonDrvEnd AS [Non Drive End], tTemperatures.dblAirIn AS [Air In], tTemperatures.dblCore AS Core, tSubTest.ixTest, tTemperatures.ixTemperature FROM (tSubTest INNER JOIN tElectricalData ON tSubTest.ixSubTest = tElectricalData.ixSubTest) LEFT JOIN tTemperatures ON tElectricalData.ixElectrical = tTemperatures.ixElectrical WHERE (((tSubTest.ixSubTestType)=5)) ORDER BY tSubTest.ixTest, tTemperatures.ixTemperature; So how come, in the form view it shows the graph with the correct data when linked thus: Child field: ixTest Master field: ixTest but won't print the graph. The graph will print if I remove the links, but then I have all the data from chart query as it is not limited by ixTest. edit #2 It seems to be a data retrieval/rendering issue in printing. Is there anything in printing that changes the context of records with respect to parent/child relationships?

  • Window title for a console application

    - by Timbo
    In Visual Studio's Attach to Process dialog, one of the columns in the Available Processes list is "Title", which lists the title of the topmost window owned by each process. We spawn multiple instances of several server processes in order to compartmentalize the work. For these console processes, the Title field is blank, so currently we have to look up the process id in our management tool in order to find the correct process. In order to streamline the debugging process, I would love to be able to use the Title field to directly determine which process I want. SetConsoleTitle does not do the trick, nor SetWindowText with a NULL hWnd. To the best of my knowledge, a console application does not intrinsically own any window handles that we could pass to SetWindowText. We don't want to create any visible windows for these server processes. Any suggestions for a reasonable way to trick Visual Studio into displaying some useful information here?

  • Django database caching

    - by hekevintran
    I have a Django form that uses an integer field to lookup a model object by its primary key. The form has a save() method that uses the model object referred to by the integer field. The model's manager's get() method is called twice, once in the clean method and once in the save() method: class MyForm(forms.Form): id_a = fields.IntegerField() def clean_id_a(user_id): id_a = self.cleaned_data['id_a'] try: # here is the first call to get MyModel.objects.get(id=id_a) except User.DoesNotExist: raise ValidationError('Object does not exist') def save(self): id_a = self.cleaned_data['id_a'] # here is the second call to get my_model_object = MyModel.objects.get(id=id_a) # do other stuff I wasn't sure whether this hits the database two times or one time so I returned the object itself in the clean method so that I could avoid a second get() call. Does calling get() hit the database two times? Or is the object cached in the thread? class MyForm(forms.Form): id_a = fields.IntegerField() def clean_id_a(user_id): id_a = self.cleaned_data['id_a'] try: # here is my workaround return MyModel.objects.get(id=id_a) except User.DoesNotExist: raise ValidationError('Object does not exist') def save(self): # looking up the cleaned value returns the model object my_model_object = self.cleaned_data['id_a'] # do other stuff

  • Good conventions for embedding schema of a flat file

    - by Ville Koskinen
    We receive lots of data as flat files: delimitted or just fixed length records. It's sometimes hard to find out what the files actually contain. Are there any well established practices for embedding the schema of the file to the beginning or the end of a file to make the file self-explanatory? Just to get an idea, imagine something like this: <data name=test records=2 type=fixed> <field name=foo start=0 length=2 type=numeric> <field name=bar start=2 length=4 type=text> </data> 11test 12ing We would parse the xml in the beginning and use it for reading the records.

  • Why is the Windows UI responds slowly after being idle for a long time?

    - by John Isaiah Carmona
    I open these applications in my desktop computer: Visual Studio 2010 Professional IBM Lotus Notes Google Chrome And when it is idle for an hour and I restore the windows, the user interface responds very slowly. My computer auto-lock itself after being idle for 5 minutes. I also minimize the applications using a docklet (RocketDock). Why is it slowing down and how can I prevent it from slowing? My OS is Windows XP Professional SP3, Pentum(R) Dual Core @ 2.80 GHz, 1.99 GB of RAM.

  • How does mysql define DISTINCT()

    - by goran
    AFAIK SQL defines two uses of DISTINCT keywords - SELECT DISTINCT field... and SELECT COUNT(DISTINCT field) ... However in one of web applications that I administer I've noticed performance issues on queries like SELECT DISTINCT(field1), field2, field3 ... DISTINCT() on a single column makes no sense and I am almost sure it is interpreted as SELECT DISTINCT field1, field2, field3 ... but how can I prove this? I've searched mysql site for a reference on this particular syntax but could not find any. Does anyone have a link to definition of DISTINCT() in mysql or knows about other authoritative source on this? Best

  • cleaned_data() doesn't have some of the entered data

    - by SC Ghost
    I have a simple form for a user to enter in Name (CharField), Age(IntegerField), and Sex(ChoiceField). However the data that is taken from the Sex choice field is not showing up in my cleaned_data(). Using a debugger, I can clearly see that the data is being received in the correct format but as soon as I do form.cleaned_data() all sign of my choice field data is gone. Any help would be greatly appreciated. Here is the relative code: class InformationForm(forms.Form): Name = forms.CharField() Age = forms.IntegerField() Sex = forms.ChoiceField(SEX_CHOICES, required=True) def get_information(request, username): if request.method == 'GET': form = InformationForm() else: form = RelativeForm(request.POST) if form.is_valid(): relative_data = form.cleaned_data

  • How JQuery data validation plugin works on the submit action

    - by kwokwai
    Hi all, I am learning how to use JQuery validation plugin, and came across some questions about the JQuery magic that works on the sumbit action. I got a simple HTML form which has got an input text field like this: <form class="cmxform" id="commentForm" method="get" action=""> <input id="cname" name="name" size="25" class="required" minlength="2" /> <input class="submit" type="submit" value="Submit"/> </form> The magic happened when I tried not to input any data into the field and pressed the submit button. I saw an error message in red pop up, and no matter how hard and how many times I pressed the submit button, nothing was submitted. It seemed that there was some scripts that disabled the submit action, but I just couldn't find which lines of codes in the JQuery Validatyion Plugin that did it.

  • Linq-to-Sql not detecting change in xml

    - by porum
    I have an xml field (Answers) in Sql Server, but when changing the content via Linq-to-Sql, the record is not flagged for updating. e.g. in Linqpad... var profile = Profiles.FirstOrDefault(p => p.Answers != null); profile.Answers.SetAttributeValue("date", DateTime.Now.ToString()); GetChangeSet().Dump(); // nothing flagged profile.Answers = new XElement(profile.Answers); // ends up with correct xml GetChangeSet().Dump(); // record is flagged as changed Any suggestions apart from assigning a clone of itself to the field or storing the xml as a string to force the update?

  • How best to implement publicly accessible constants in C#

    - by DanM
    There seem to be three choices for implementing publicly accessible constants in C#. I'm curious if there are any good reason to choose one over the other or if it's just a matter of personal preference. Choice 1 - private field plus property getter private const string _someConstant = "string that will never change"; public string SomeConstant { get { return _someConstant; } } Choice 2 - property getter only public string SomeConstant { get { return "string that will never change"; } } Choice 3 - public field only public const string SomeConstant = "string that will never change"; Which do you recommend and why?

  • How do I make a view that groups nodes by taxonomy term?

    - by Andrew Weir
    Hello, I'm trying to bend views and drupal to my will. So far I've produced a view to display the titles of my nodes. Each node will be assigned exactly one taxonomy term from the set {X, Y and Z}. So for example, Node A has a title "Car drives into field, thousands don't care". Node A has a taxonomy term "Pointless". I'd like to group all the node titles by their taxonomy term. So.. Pointless - Car drives into field, thousands don't care - .... Next Taxonomy Term - ..... - ...... - ... You get the idea. Is it doable and how do I do it? I can't find the group by option in views. cheers SO.

  • CakePHP: How do I order results based on a 2-level deep association model?

    - by KcYxA
    I'm hoping I won't need to resort to custom queries. A related question would be: how do I retrieve data so that if an associated model is empty, no record is retrieved at all, as opposed to an empty array for an associated model? As an oversimplified example, say I have the following models: City -- Street -- House How do I sort City results by House numbers? How do I retrieve City restuls that have at least one House in it? I don't want a record with a city name and details and an empty House array as it messes up pagination results. CakePHP retrieves House records belonging to the Street in a separate query, so putting somthing like 'House.number DESC' into the 'order' field of the search query returns a 'field does not exist' error. Any ideas?

  • asp.net mvc validation must be a number custom error

    - by Para
    Hi, I am new to asp.net and I have a problem. When the users insert in a editor for a decimal field something other than numbers, they get an error "Field name" is not a number. But I don't want them to receive this message I want them to receive another message. I have no problem with this with required and range validators. Is there any way for me to do this? I am not refering necessarily to changing the culture just displaying another message. Thanks.
