  • Problem with DataGrid_CellFormatting event to set default value

    - by Royson
    Hi, I have created an applicationto display list of files. it also provide user interface for adding new column to a gridview. DataGridViewTextBoxColumn txtBoxColumn = new DataGridViewTextBoxColumn(); txtBoxColumn.Name = columnName; txtBoxColumn.HeaderText = columnName; g_dataGridView.Columns.Add(txtBoxColumn); User will create some custom type column therefore i am adding column directly to grid. I am also able to set its default value before adding for this i am using DataGrid_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e) { if (colIndexWithDefaultValue.Count > 0) { if (colIndexWithDefaultValue.Contains(e.ColumnIndex)) { g_dataGridView.Rows[e.RowIndex].Cells[e.ColumnIndex].Value = colIndexWithDefaultValue[e.ColumnIndex]; } } } where colIndexWithDefaultValue is list of columns with its default value. It is able to show newly created column with default value. But values are getting set for currently visible rows. To set value for all rows i have to do scrolling. So, how do i overcome this problem...

  • The standard map/associative-array structure to use in flash actionscript 3?

    - by tstyle
    I'm relatively new to flash, and is confused about what I should use to store and retrieve key value pairs. After some googling I've found various map-like things to choose from: 1) Use a Object: var map:Object = new Object(); map["key"] = "value"; The problem is that it seems to lack some very basic features. For example to even get the size of map I'd have to write a util method. 2) Use a Dictionary What does this standard library class provide over the simple object? It seems silly for it to exist if it's functionally identical to Object. 3) Go download some custom HashMap/HashTable implementation from the web. I've used a lot of modern languages, and this is the first time I haven't been able to find a library implementation of an associative array within 5 minutes. So I'd like to get some best-practice advice from an experienced flash developer. Thanks!

  • Java Authenticator on a per connection basis?

    - by Martijn Laarman
    I'm building an Eclipse plugin that talks to a REST interface which uses Basic Authentication. When the authentication fails I would like to popup my plugin's settings dialog and retry. Normally I could use the static Authenticator.setDefault() to setup an authenticator for all HttpURLConnection's for this, but since I am writing a plugin I don't want to overwrite Eclipse's default Authenticator (org.eclipse.ui.internal.net.auth); I thought of setting my custom Authenticator before loading and putting Eclipse's default back afterwards, but I imagine this will cause all sorts of race issues with multithreading so I quickly lost that notion. Google searches yield all sorts of results basically telling me it's not possible: The Java URLConnection API should have a setAuthenticator(Authenticator) method for making it easier to use this class in multi-threaded context where authentication is required. Source If applications contains few third party plugins and each plugin use its own Authenticator what we should do? Each invocation of "Authenticator.setDefault()" method rewrite previously defined Authenticator... Source Are there any different approaches that might help me overcome this issue?

  • python mock side_effect or return_value dependent on call_count

    - by user18380
    To test a polling function I want to mock the calling of a sub function so that the first time it is called it will fail, and the second time it is called it will succeed. Here's a very simplified version of it: poll_function(var1): value = sub_function(var1) # First call will return None while not value: time.sleep(POLLING_INTERVAL) value = sub_function(var1) # A subsequent call will return a string, e.g "data" return value Is this possible to do with a Mock object from the mock framework? I know Mock objects have a call_count attribute I should be able to use somehow. Right now I've solved it by creating a custom mock object that I use to monkey patch sub_function(), but I feel there should be a better less verbose way of doing it: def test_poll(): class MyMock(object): def __init__(self, *args): self.call_count = 0 def sub_function(self, *args, **kwargs): if self.call_count > 1: return "data" else: self.call_count += 1 return None my_mock = MyMock() with patch('sub_function', my_mock.sub_function): ok_(poll_function())

  • What can cause the language bar to disappear in a win32 application?

    - by user4484
    When I run my Win32 application the Windows language bar (which is visible in all other applications) disappears after about 5 seconds. It reappears if I quit my application or alt-tab to a different application. If I alt-tab back into my application, it disappears again after five seconds. The switch key doesn't work either. It seems as if the system somehow has concluded that my application doesn't "support" the language bar. Is there something I need to do to for the language bar to be enabled? Or something I shouldn't be doing that can cause it to disappear? The application has a single custom window (where I draw DirectX graphics). I've looked through the arguments to CreateWindow and RegisterClass as well as the window messages that I handle (instead of passing to DefWindowProc) but nothing seems to be directly related to the language bar. I've only tested this on Windows 7.

  • Visual Studio project build as an executable AND a DLL

    - by East of Nowhere
    In Visual Studio 2008 project properties, Application tab, I can set the Output type to Windows Application, Console Application, or Class Library. I have a project that I want to build as a stand-alone tool (console app) and be available to a couple other tools I'm working on as a class library. The VS GUI only lets me choose one or the other, and building the proj twice all the time is inconvenient. How can I set it up to build both output types in a single build job? Do I write some custom MSBuild .targets file or what?

  • How to link to a folder in document library from sharepoint list item?

    - by kyrisu
    Hi, Background: I have an items on the sharepoint list. I also have a corresponding folder in a document library that contains documents about this item. I want to be able to get to this folder straight from the item properties. I have tried to create a lookup column containing folder ID, but that doesn't help cause folder is not a type and it just doesn't work. Other solution would be to create link column but if I will create it staticly - after creating alternative mapping (and getting to the page from the internet for example) it won't work. (so solution posted here won't work for me). I want to create this link from sharepoint workflow. I have a custom action that can return any info about the folder I want (ID, URL etc). Question: How to link from sharepoint list item to a folder in document library?

  • Problem with validating ModelForm

    - by user561640
    I use ModelForm to create my form. All works fine except 1 thing - validating the unique field. Code: class Article(models.Model): ... title = models.CharField(max_length=255, unique=True, error_messages={'max_length' : 'max translation', 'unique' : 'unique translation', 'required' : 'req translation',}) ... class ArticleForm(ModelForm): ... title = forms.CharField(max_length=255, min_length=3, error_messages={'required' : 'req translation', 'min_length' : 'min translation', 'max_length' : 'max translation', 'unique' : 'unique translation',}) But when I save my form with non-unique title I don't get my custom translated error but I get default error. How to fix it, that my unique field error is displayed?

  • How to center text in a select list

    - by Micah
    I'm having trouble styling a select list in an html form. Basically I want it to have a font size of 12px, and a height of 30px; The problem is that the box is drawn to the right hight, but the text rendering varies in each browser. In FireFox it renders it in the top left corner. I want to vertically center the text. Anyone know of a way to do this or do I need to make something custom out of a ul? Thanks

  • Capistrano update causes C: to be placed in the current directory (cygwin)

    - by user321775
    When I run cap deploy:update in a directory on my local machine (via cygwin), "C:" magically appears in the directory. Sure enough, I can cd to it and it's my windows C: drive. Now I'm afraid to delete it, but I definitely don't want it in this directory (a rails project under /home/username/blah/blah). Here's my config/deploy.rb file. custom options set :application, "xyz.com" set :repository, "ssh://[email protected]:yyyy/home/git/xxx" set :user, "myname" set :runner, user set :use_sudo, false server "xxx.xxx.xxx.xxx:yyyy", :app, :web, :db, :primary = true deploy to set :deploy_to, "/home/myname/public_html/xyz" repository set :scm, :git set :deploy_via, :copy ssh options default_run_options[:pty] = true ssh_options[:paranoid] = false ssh_options[:port] = yyyy start passenger namespace :deploy do task :start do ; end task :stop do ; end task :restart, :roles = :app, :except = { :no_release = true } do run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}" end end Anyone see the problem? And does anyone know a safe way of getting rid of the C: drives that have already shown up (this has happened in a few directories)?

  • Mysql search design

    - by neil
    I'm designing a mysql database, and i'd like some input on an efficient way to store blog/article data for searching. Right now, I've made a separate column that stores the content to be searched - no duplicate words, no words shorter than four letters, and no words that are too common. So, essentially, it's a list of keywords from the original article. Also searched would be a list of tags, and the title field. I'm not quite sure how mysql indexes fulltext columns, so would storing the data like that be ineffective, or redundant somehow? A lot of the articles are on the same topic, so would the score be hurt by so many of the rows having similar keywords? Also, for this project, solutions like sphinx, lucene or google custom seach can't be used -- only php & mysql. Thanks!

  • How to show raw_id value of a ManyToMany relation in the Django admin?

    - by luc
    Hello, I have an app using raw_id on both ForeignKeyField and ManyToManyField. The admin displays the value of the foreign key on the right of the edit box. Unfortunatey, it doesn't work with ManyToMany. I've checked the code and I think that it is the normal behavior. However I would like to know if someone has an easy tip to change this behavior? Thanks in advance Update: I've tried to subclass the ManyToManyRawIdWidget but I don't know how to say that the raw_id_fields should use my custom widget. formfield_overrides doesn't seem to work with raw_id fields

  • Should the name of my classes begin with 'Q' in Qt?

    - by Venemo
    Hello Everyone, When I first started working with Qt, it was extremely annoying that every class has a name beginning with 'Q', but now I've got used to it. I'm using Qt Creator, and it highlights code quite well. However, it only highlights class names beginning with 'Q'. And it highlights everything beginning with 'Q' even if there is no such type. It doesn't highlight custom class names. That makes me wonder, should I also begin all my class names with 'Q'? Or at least the reusable ones? (I mean, those that I put in a class library, or reuse in another app.) I've seen several places where they named their classes this way. Is it a good thing? I found this page about Qt's naming conventions, but it doesn't deal with this question. Also, I don't understand why Qt doesn't use namespaces.

  • Is there a faster way to draw text?

    - by mystify
    Shark complains about a big performance hit with this line, which takes like 80% of CPU time. I have a counter that is updated very frequently and performance seriously sucks. It's an custom UILabel subclass with -drawRect: implemented. Every time the counter value changes, this is used to draw the new text: [self.text drawInRect:textRect withFont:correctedFont lineBreakMode:self.lineBreakMode alignment:self.textAlignment]; When I comment this line out, performance rocks. Its smooth and fast. So Shark isn't wrong about this. But what could I do to improve this? Maybe go a level deeper? Does that make any sense? Probably drawing text is really so incredible heavy...?

  • Retrieving Large Lists of Objects Using Java EE

    - by hallidave
    Is there a generally-accepted way to return a large list of objects using Java EE? For example, if you had a database ResultSet that had millions of objects how would you return those objects to a (remote) client application? Another example -- that is closer to what I'm actually doing -- would be to aggregate data from hundreds of sources, normalize it, and incrementally transfer it to a client system as a single "list". Since all the data cannot fit in memory, I was thinking that a combination of a stateful SessionBean and some sort of custom Iterator that called back to the server would do the trick. How have you successfully solved this problem in the past?

  • using AutoCompleteTextField in wicket without String as the generic type

    - by Manuel
    Hi! This question follows this: handling to onchange event of AutoCompleteTextField in wicket I'm trying to use the AutoCompleteTextField with a custom class as the generic type, and to add an AjaxFormComponentUpdatingBehavior. What I mean is I want to have a AutoCompleteTextField<SomeClass> myAutoComplete = ...; and after that add a AjaxFormComponentUpdatingBehavior: myAutoComplete.add(new AjaxFormComponentUpdatingBehavior("onchange") { @Override protected void onUpdate(AjaxRequestTarget target) { System.out.println( "Value: "+getValue() ); } }); The problem is that for some reason, adding that behavior makes the form try to set the model object with a String (even though the AutoCompleteTextField has a generic type of SomeClass), causing a ClassCastException when the onchange event fires. Is there a way to use AutoCompleteTextField without it being AutoCompleteTextField<String>? I couldn't find any example. Thanks for your time! and thanks to the user biziclop for his help in this matter.

  • JQUERY: Multiplying input elements select box and radio boxes and hidden inputs

    - by Andrew Tan
    Evening, I'm tyring to multiply different input elements but for some reason it's giving me a NAND error. As the user selects, check or modify the values of any element. This should change the total amount. http://jsfiddle.net/aQ5K8/ <select name="select"> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> </select> <input name="radio" type="radio" id="radio" value="10" tvalue="100" /> <input name="radio" type="radio" id="radio" value="20" tvalue="200" /> <label id="Total"></label> Also if you take a look at the jsfiddle code i have tvalue=100 and the other is =200 as a custom attributes, how would I access that instead of accessing the regular html value. Thank you.

  • Field annotated multiple times by the same attribute

    - by Jaroslaw Waliszko
    For my ASP.NET MVC application I've created custom validation attribute, and indicated that more than one instance of it can be specified for a single field or property: [AttributeUsage(AttributeTargets.Field | AttributeTargets.Property, AllowMultiple = true)] public sealed class SomeAttribute: ValidationAttribute I've created validator for such an attribute: public class SomeValidator : DataAnnotationsModelValidator<SomeAttribute> and wire up this in the Application_Start of Global.asax DataAnnotationsModelValidatorProvider.RegisterAdapter( typeof (SomeAttribute), typeof (SomeValidator)); Finally, if I use my attribute in the desired way: [SomeAttribute(...)] //first [SomeAttribute(...)] //second public string SomeField { get; set; } when validation is executed by the framework, only first attribute instance is invoked. Second one seems to be dead. I've noticed that during each request only single validator instance is created (for the first annotation). How to solve this problem and fire all attributes?

  • Explicitly persist states in Workflow 4.0 rather than everything.

    - by jlafay
    I have ran into an issue with my SQL instance store attached to a WorkflowApplication that is running. When I exit my application I'm calling an Unload() on the WF app to persist it. I didn't think about it during design time, but it does makes sense, it's persisting an arg that was passed in to the WorkflowApplication constructor when instanced. When the application runs, everything in the workflow works as expected. When I call Unload() I get an unhandled exception that states that the arg is not serializable and needs [DataContractAttribute]. What's passed into the workflow is my applications custom logger object that I wrote so that the WF can log to disk in a uniform way that I prefer. How do I prevent the workflow app from persisting this one argument and persist everything else? I'm sure something can be done with extensions but I'm having a hard time finding info on them or finding persistence examples for my scenario.

  • Running an app that requires an administrator account from a service

    - by Bergvall
    Is it possible to run handle.exe (from sysinternals) from a service (in windows7) without having to turn off UAC? The service is a custom c-app that needs to find out which process is locking a file it tries to access and handle.exe seems to be a good way to solve it but i can't get it to work with UAC turned on. This app runs all the time so i can't have a UAC prompt while its running but its fine if it shows up at startup. Handle.exe works fine from an admin commandprompt but fails when trying to run from a normal prompt. I call handle.exe from CreateProcess() and get the output from pipes. I guess there should be a way to solve this but i can't figure it out. Setting up the service to log in from an admin account does not seem to work.

  • Application crashes when popViewControllerAnimated is called while scrolling

    - by Aldrich
    In one screen I have a custom toolbar with a "close" button in it, and a UIScrollView. In the screen that preceded this one I had pushed the current screen into the navigation stack. I had also disabled the navigation toolbar for a larger display area and so the close button would instead be used to call: - (void)doClose { [self.navigationController popViewControllerAnimated:YES]; } Now here's the problem: the application crashes when the close button is pressed, while the UIScrollView is moving. Here's the debugger stack trace: 0 __forwarding__ 1 __forwarding_prep_0___ 2 -[UIToolbarButton setHighlighted:] 3 -[UIControl(Static) _unhighlight] 4 __NSFireDelayedPerform ... and I do have the following line in the debugger console: *** -[CALayer setOpacity:]: message sent to deallocated instance 0x718d250 (sometimes setOpacity would be setNeedsDisplay or something related) There won't be any crashes while the scrollview is at rest. What is happening?

  • Windows Service Fails on Launch

    - by Jeff
    I'm trying to write a windows service. It installs fine, but fails when I run it with the following exception. I've searched for the string "MyNewProgramService", but I can't find any conversions that would throw this error. I've also added try/catch blocks to a bunch of code with custom exception handling without finding where this exception is occuring.

  • How to dynamically load and switch the resource file in the web app (ASP.NET) without recompiling ?

    - by Thomas Wanner
    I would like to store the resource files (containing texts for labels etc.) for my web application in the database to be able to edit and create them dynamically later (probably in the UI). My idea was to store the whole resx file in an xml column and simply load it on demand - depending on the language and some other attributes of the current user when he is logging into the application or switching the context. The important thing is that the resources do not only depend on the culture info of the user but also on some context information that can be switched by user without logging off and on again (in our case called "group", not having anything to do with a group of users). Is it possible somehow to load the contents of the resources from an external source and simply switch them without web application being recompiled by the server ? I know that there are some interfaces on which I could hook up and implement a custom resources provider which reads from the database directly but if it could work somehow with the resx files it would probably make things a lot easier..
