• Copying data across tabs

  - by Guillermo

  Hello, I got two different forms in two different tabs. One has data from our system and the other one is an interface of another, external, system in wich we need to copy data into (XML or API integration not an option here) The this is that, having open both forms - in two different tabs - i need a greasemonkey script or something similar that allows my to copy data from one form to the other (using the getValue method in Javascript). The problem right now is that I cannot figure out how to reference with a greasemonkey script one particular tab or window (to rad data from or write data to). Do you think it would be possible to do what I'm thinking to do? THANKS

• Looking for a component (.NET or COM/ActiveX) that can play AVI files in a WinForms app

  - by MusiGenesis

  I'm looking for something like the Windows Media Player control that can be hosted on a form. The WMP doesn't work for me because I need a control that can play a continuously-appended playlist of AVI files in sequence, so that the transition from one file to the next happens seamlessly (i.e. without any glitches or pauses in the video and audio). With WMP, there's always a delay between files of half a second or so. Does anyone know of a control (it can be either commercial or open-source) that can do this? I assume anything like this wraps DirectX, and that's OK too.

• ASP Calendar control returns Date type but I need Datetime to insert into SQL Server 2005

  - by rafael

  Hello, I am using a ASP Calendar control to insert a datetime value into a field to be part of an insert to a SQL Server 2005 db table. I get the following error when i submit the form to server and try to insert into table: [ArgumentException: The version of SQL Server in use does not support datatype 'date'.] Seems like Calendar control returns a Date type value. How could i make the Calendar control return a Datetime value instead? I know now that SQL Server 2005 does not support Date type fields.

• How to synch SQLite data to server in iPhone

  - by crawler486

  Hello Guys, I'm a total noob when it comes to iPhone development and have been tasked to create a database app that can download and upload sqlite data to and from a server via http using web services. So far I already have a form for retrieving and saving data to a SQLite database and now I need some information on how I can upload the SQLite data to a server. The SQLite database will only have one table with 3 columns and about 200 rows max. I hope somebody can point me to the right direction or lead me to some sample codes. Appreciate any help.

• Make NSFormatter validate NSTextFieldCell continuously

  - by harms

  In Cocoa, I have an NSOutlineView where the cells are NSTextFieldCell. The cell displays values which are strings that are formatted according to certain rules (such as floats or pairs of floats with a space in between). I have made a custom NSFormatter to validate the text, and this seems to work with no problem. However, the cell (or the outline view, I'm unsure what is causing this) only seems to use the formatter at the moment my editing would end. If I type some alphabetic characters into the text field (which violates the formatting rules), these characters show up -- the only way I notice the formatter doing its job is that I'm now prevented from moving keyboard focus away from this cell. If I return the contents of the cell to a valid form, then I can move focus away. I have set both the cell and the outline view to be "continuous". It would be better if I was unable to enter text into the cell in the first place. Is it possible to make it like that, and if so, how?

• What tools are people using to measure SQL Server database performance?

  - by Paul McLoughlin

  I've experimented with a number of techniques for monitoring the health of our SQL Servers, ranging from using the Management Data Warehouse functionality built into SQL Server 2008, through other commercial products such as Confio Ignite 8 and also of course rolling my own solution using perfmon, performance counters and collecting of various information from the dynamic management views and functions. What I am finding is that whilst each of these approaches has its own associated strengths, they all have associated weaknesses too. I feel that to actually get people within the organisation to take the monitoring of SQL Server performance seriously whatever solution we roll out has to be very simple and quick to use, must provide some form of a dashboard, and the act of monitoring must have minimal impact on the production databases (and perhaps even more importantly, it must be possible to prove that this is the case). So I'm interested to hear what others are using for this task? Any recommendations?

• Correct way to Convert 16bit PCM Wave data to float

  - by fredley

  I have a wave file in 16bit PCM form. I've got the raw data in a byte[] and a method for extracting samples, and I need them in float format, i.e. a float[] to do a Fourier Transform. Here's my code, does this look right? I'm working on Android so javax.sound.sampled etc. is not available. private static short getSample(byte[] buffer, int position) { return (short) (((buffer[position + 1] & 0xff) << 8) | (buffer[position] & 0xff)); } ... float[] samples = new float[samplesLength]; for (int i = 0;i<input.length/2;i+=2){ samples[i/2] = (float)getSample(input,i) / (float)Short.MAX_VALUE; }

• JComponent undock effect

  - by Christo Du Preez

  I'm trying to accomplish an undock effect for a custom Swing JComponent. By default the component is used inside a form along with other components. I want to be able to maximize this component to use the whole screen and then be able to dock it again. So far I've tested public void showDialog() { JFrame mainFrame = App.getApplication().getMainFrame(); JDialog dialog = new JDialog(mainFrame); dialog.setModal(true); dialog.setSize(800, 600); //Set to 80x660 for now dialog.add(this); //This is my JComponent dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE); dialog.setVisible(true); } This gives me desired effect but when closing the dialog my component doesn't receive events no more. How can I prevent this? Or is there perhaps a better way to accomplish this?

• WPF integrate Windows live authentication for windows health vault

  - by AnD

  Hi all, I'm just wondering if there's any way for WPF application integrated with windows live ID? and it's actually for windows health vault [www.healthvault.com] so health vault is using windows live id or open id to login into their system. and what i gonna do is, creating wpf application (instead of web application) for health vault, so all of the login form username pass and everything is handled inside the wpf application without showing/using any internet browser. so since this's quite new for me, i hope if there's somebody ever did this before especially for health vault system that run on standalone wpf app. alright, so that's it, thank you in advance!

• ODBC and Windows Service

  - by DNS

  Hi, I'm new to windows services and... you guessed it, I’m a bit stuck. Let me paint the picture – I’m running a timed service that use an OdbcDataReader and SqlBulkCopy to (1) archive the data (2) normalize the data on a SQL box. When I run this code in a windows form proj. it works fine. Then, when I change the DNS’s Data Directory Path to a local drive, instead of the network share (just simulated the environment locally), it works as well. I’m obviously missing something. Any help will be appreciated. DNS

• Gmail-like labelling system

  - by Dimitris

  Hi I am looking into a number of ways to implement a labelling system similar to the one in Gmail. Basically I have a Resource at the lowest level and I would like to provide a number of organisational groupings for that resource in the form of labels. If anyone has implemented something like that I would like to hear your views. My idea is to have within the Resource instance a List<Label>. I need to have an efficient mechanism in order to do very fast searches based on the labels or based on the resources. Thanks Dimitris

• Rails I18n accepts_nested_attributes_for and error_messages_for

  - by Mike

  I've got two models class SurveyResponse has_many :answers, :class_name => SurveyResponseAnswer.name accepts_nested_attributes_for :answers end class SurveyResponseAnswer belongs_to :survey_response validates_presence_of :answer_text end In my nested form if validation fails I get this error displayed on the screen: "answers answer text can't be blank" I've customized my attribute names somewhat successfully using rails I18n. It doesn't behave exactly how I would expect though. The yml file below doesn't affect how the attribute name is printed in error_messages_for en: activerecord: models: survey_response: answers: "Response" But if from script/console I try SurveyResponse.human_attribute_name("answers") I get the expected result of "Response". What I'd like to do is have the validation error message say: "Response answer text can't be blank". Any ideas what I need to fix?

• C# UserControl factory

  - by user1112111

  Let's say you have two classes that extend UserControl. Each of the controls provides a custom event (this could be done by using an interface). You want to display one of the controls in the odd days and the other in the even days. You also want to be able to drag&drop (Visual Studio) the UserControl on your form without knowing what the Control type will finally be. How do you do that ? Is the factory pattern useful here ?

• Greek/latin scientific JLabel in Java Swing application

  - by MartinStettner

  For a scientific application I want to design an input form which lets the user enter certain parameters. Some of them are designated using greek letters, some of them have latin letters. The parameter names should be displayed using ordinary JLabel controls. On Windows, the Tahoma font (which is used for Labels by default) contains both latin and greek letters, so I simply set the Text property of the label to a greek (unicode) string and everything works fine. I'm wondering if this works also without modifications on Linux and OSX systems resp. for which Java/OS versions this would work. Also I'm curious if there's an easy way to show subscripts in labels ("\eta_0" in TeX), but this is not that important for my application ...

• SharePoint Lookup Field 20 Item JS error

  - by Chops

  Hi Everyone, I've got an issue with SharePoint Server 2007 SP1 which seems to be documented in various forms, but I haven't been able to find an answer to my seemingly simpler question. http://social.msdn.microsoft.com/Forums/en-US/sharepointcustomization/thread/040533d2-c738-4ac2-b2d6-65a1602fa2d1 Essentially, we have a form with a lookup field to another SharePoint list. The lookup field has more than 20 items, and so SharePoint changes the type/behaviour of the field as per the standard behaviour. However, with my custom skin applied, clicking on this drop down causes a JS error from within the Core.js file, as described here: http://splitnut.blogspot.com/2009/06/lookup-fields-in-moss-javascript-error.html What I haven't been able to figure out is why this is only an issue when my custom master page is applied, and not the OOTB master pages. I've been through and tried to see what might cause this, but haven't been able to track down the cause of the behaviour. Any help would be much appreciated. Many thanks.

• JavaScript: What is AJAX? What is jQuery?

  What exactly IS AJAX? Is there an official release? What exactly is jQuery? Is there an official release? From what I understand, these two "extensions" of JavaScript are just small scripts that enable extended functionality. But, what exactly are there? I mean, Adobe is a company that created Flash. If you want information about Flash, the official source is at Adobe. Is there an equivalent for AJAX and jQuery? I don't want to learn AJAX or jQuery form some shmo that doesn't know that correct syntax. I want to learn proper syntax and best practices.

• Creating a new nested resource

  - by Bobby B

  I'm working on a basic garden logging application which consists of gardens, plants and planted plants. Each user has one or many gardens, plants are master definitions, and a planted plant can be thought of as an instance of a plant in a specific user's garden. In my routes.rb file I have the following: map.resources :gardens do |gardens| gardens.resources :planted_plants, :has_many => :plant_log_entries, :collection => { :filter => :post, :choose_garden => :post} gardens.resources :garden_log_entries end map.resources :plants This makes sense to me when retrieving a list of planted_plants in a user's garden, but I'd like to create a planted_plant record from the index of plant. The problem is, a user can have multiple gardens. How can I create a new form for a planted_plant that allows the user to specify which garden should be used? The current route requires a garden_id - which makes sense for retrieval, but I'd like to supply that as a parameter for creation. Thanks in advance for any help!

• Simulate the user clicking on a link

  - by timkl

  I want a link to be clicked when a key is pressed, I cooked up this jQuery: $('form#form1').bind("keypress", function(e){ if(e.keycode == 13 || e.keyChar == 13 || e.which == 13){ $('.LoginBoxButton a').click(); } }); It doesn't work, and I've read the following explaining why: It's important to remember that click() will not trigger the default behavior on a link, even if nothing else is preventing it. So you can't use click() by itself to simulate the user clicking on a link and being taken to another url. But how DO you simulate the user clicking on a link and being taken to another url?

• Filtering Filenames with bash

How can I avoid that *.log.old file is included in the LIST attribute? Thank you Stefan

• Can I develop for .NET Framework 4 in Visual Studio 2008?

  - by Zack Peterson

  My ASP.NET application runs in IIS on my web server and uses Microsoft .NET Framework 4 Beta 2. (Its Application Pool is set to .NET Framework version .NET Framework v4.0.21006.) It gives this new error: A potentially dangerous Request.Form value was detected from the client... This is due to a breaking change in .NET 4. To revert to the behavior of the ASP.NET 2.0 request validation feature, I added the following setting in the Web.config file: <httpRuntime requestValidationMode="2.0" /> Now Visual Studio 2008 throws a compile-time error: The 'requestValidationMode' attribute is not declared. And I can no longer debug on my development machine using the ASP.NET Development Server that comes with Visual Studio. I need Visual Studio and its ASP.NET Development Server to recognize the new .NET Framework 4 requestValidationMode attribute. How can I debug my application in .NET 4? Must I switch from Visual Studio 2008 to Visual Studio 2010 Beta 2?
