  • Help needed with InvokeRequired for Web.UI

    - by Ali
    I have a multi-threaded application in C# which tries to write to a TextBox in a Windows.Forms created by another thread. As threads cannot modify what has not been created by them, I was using InvokeRequired as shown on the code below, to solve this problem. public delegate void MessageDelegate(Communication message); void agent_MessageReceived(Communication message) { if (InvokeRequired) { BeginInvoke(new MessageDelegate(agent_MessageReceived), new object[] { message }); } else { TextBox1.Text += message.Body; } } Now I need to do the same for a TextBox in an ASP.NET app, but apparently neither InvokeRequired nor BeginInvoke exist for TextBox in a Web.UI. What can I do?

  • Django version in GAE

    - by Alex
    I'm tring to use Django 1.1 in GAE, But when I uncomment use_library('django', '1.1') in this script import os os.environ['DJANGO_SETTINGS_MODULE'] = 'settings' from google.appengine.dist import use_library #use_library('django', '1.1') # Google App Engine imports. from google.appengine.ext.webapp import util # Force Django to reload its settings. from django.conf import settings settings._target = None import django.core.handlers.wsgi import django.core.signals import django.db import django.dispatch.dispatcher # Unregister the rollback event handler. django.dispatch.dispatcher.disconnect( django.db._rollback_on_exception, django.core.signals.got_request_exception) def main(): # Create a Django application for WSGI. application = django.core.handlers.wsgi.WSGIHandler() # Run the WSGI CGI handler with that application. util.run_wsgi_app(application) if __name__ == "__main__": main() I receives AttributeError: 'module' object has no attribute 'disconnect' What is going on?

  • jQuery parent of a parent

    - by Bloudermilk
    Hello, I am currently trying to find the parent of a parent of an element. I have a link being clicked that is in a <td>, and I'd like to get the <tr> object. Why wont "$(this).parent().parent()" work? What will? Thanks, Brendan Edit: It appears an error in my syntax was throwing the whole thing off. "$(this).parent().parent()" does in fact work, but I wound up going with $(this).closest('tr')" because it seems like the most efficient solution.

  • Extract item in a list if Contains returns true

    - by Matt
    I have two lists A and B, at the beginning of my program, they are both filled with information from a database (List A = List B). My program runs, List A is used and modified, List B is left alone. After a while I reload List B with new information from the database, and then do a check with that against List A. foreach (CPlayer player in ListA) if (ListB.Contains(player)) ----- Firstly, the object player is created from a class, its main identifier is player.Name. If the Name is the same, but the other variables are different, would the .Contains still return true? Class CPlayer( public CPlayer (string name) _Name = name At the ---- I need to use the item from ListB that causes the .Contains to return true, how do I do that?

  • Updating the datalist in a RadComboBox

    - by jphenow
    So I'm just struggling with a lot of little things in the web app so I'm checking up with all kinds of stuff to make sure i'm not breaking it cause of stupid problems. At some point in my web app (trying to keep it mostly Asynchronous) I have to update the list in my RadComboBox because something was added. Do I just need to call RadComboBox.DataBind() again? Since I don't explicitly use its datasource(I do it in the manual insert using a string fashion) object to insert my new record do I need to tell that to update? The list just doesn't seem to update when i just call databind so I feel like i need to have the datasource recheck for entries or SOMETHING Thanks

  • Creating a Web Wrapper for COM and OCX

    - by balexandre
    Hi guys, Today we have a windows application that, using an OCX, creates a web page (visible by a WebBrowser control in a small .NET WinForm application) and communicates through COM to the main application/client. (not relevant but this is Pascal) I'm currently responsible to re create this application in a web environment so we can have the same functionality shared through Web as the user can see the same in a Web Browser. The Windows application has almost 4 years on it and I need to re create everything from scratch, and all the bugs/features find in the future in the Windows Application I have to re create them again in the Web... Ohh well, you can see where this will end. I was thinking... is there any way I can create a Wrapper, even using 3rd party commercial objects, to: Communicate with the COM Object Can expose the content of the OCX (this in my most confortable language, ASP.NET C#, but other are welcome) I was thinking out loud, can this be accomplish with a Java Applet? Any ideas or any point to the right road will be appreciated.

  • Derived Column Editor

    - by Rob Bowman
    Hi I need to assign a formatted date to a column in a data flow. I have added a Derived Column editor and entered the following expression: "BBD" + SUBSTRING((DT_WSTR,4)DATEADD("Day",30,GETDATE()),1,4) + SUBSTRING((DT_WSTR,2)DATEADD("Day",30,GETDATE()),6,2) + SUBSTRING((DT_WSTR,2)DATEADD("Day",30,GETDATE()),9,2) The problem is that the "Derived Column Transformation Editor" automatically assigns a Data Type of "Unicode string[DT_WSTR]" and a length of "7". Howver, the length of a string is 11, therefore the following exception is thrown each time: [Best Before Date [112]] Error: The "component "Best Before Date" (112)" failed because truncation occurred, and the truncation row disposition on "output column "Comments" (132)" specifies failure on truncation. A truncation error occurred on the specified object of the specified component. Does anyone know why the edit is insisting on a length of 7? I don't seem to be able to change this. Many thanks, Rob.

  • Not able to capture Enter key in WinForms text box

    - by Michael Hermes
    When the user is entering a number into a text box, I would like them to be able to press Enter and simulate pressing an Update button elsewhere on the form. I have looked this up several places online, and this seems to be the code I want, but it's not working. When data has been put in the text box and Enter is pressed, all I get is a ding. What am I doing wrong? (Visual Studio 2008) private void tbxMod_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Enter) { btnMod.PerformClick(); } }

  • How to inject JPA EntityManager using spring

    - by marcos
    Hello all! I have a few questions about jpa + spring integration running on tomcat, i've been looking fo some time and couldn't find any concrete answer, so here it goes: Is it possible to have spring to inject the JPA entityManager object into my DAO class without extending JpaDaoSupport? if yes, does spring manage the transaction in this case? I'm trying to keep spring configuration as simple as possible: <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="em"/> </bean> <bean id="em" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"> <property name="persistenceUnitName" value="myPU"/> </bean> EDIT: that was very helpfull, thank you all!

  • How do I get an unexpanded REG_EXPAND_SZ string from a remote registry?

    - by dalehhirt
    I am currently using RegistryKey.GetValue(string name, object defaultValue, RegistryValueOptions options) with RegistryValueOptions.DoNotExpandEnvironmentNames for the options value. However, this is only valid when run on the local machine. Digging down via Reflector, I find it expands the strings locally. Which means that irrespective of the setting, the strings come down remotely already expanded. Has anyone come across a solution to this that does not require running a process directly on the remote machine to get a REG_EXPAND_SZ value? Update: I attempted to use WMI's StdRegProv provider to gain access, but it still expands the strings before sending them back.

  • [WPF] SelectionChanged of a child ListBox

    - by quimbs
    Hi, I have a ListBox bound to an ObservableCollection with an ItemTemplate that contains another ListBox. First of all, I tried to get the last selected item of all the listboxes (either the parent and the inner ones) from my MainWindowViewModel this way: public object SelectedItem { get { return this.selectedItem; } set { this.selectedItem = value; base.NotifyPropertyChanged("SelectedItem"); } } So, for example, in the DataTemplate of the items of the parent ListBox I've got this: <ListBox ItemsSource="{Binding Tails}" SelectedItem="{Binding Path=DataContext.SelectedItem, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}"/> The problem now, is that when I select an item from the parent ListBox and then an item from a child listbox, I get this: http://i40.tinypic.com/j7bvig.jpg As you can see, two items are selected at the same time. How can I solve that? Thanks in advance.

  • How far does Dependency Injection reach?

    - by Baddie
    My web app solution consists of 3 projects: Web App (ASP.NET MVC) Business Logic Layer (Class Library) Database Layer (Entity Framework) I want to use Ninject to manage the lifetime of the DataContext generated by the Entity Framework in the Database Layer. The Business Logic layer consists of classes which reference repositories (located in the database layer) and my ASP.NET MVC app references the business logic layer's service classes to run code. Each repository creates an instance of the MyDataContext object from the Entity Framework Repository public class MyRepository { private MyDataContext db; public MyRepository { this.db = new MyDataContext(); } // methods } Business Logic Classes public class BizLogicClass { private MyRepository repos; public MyRepository { this.repos = new MyRepository(); } // do stuff with the repos } Will Ninject handle the lifetime of MyDataContext despite the lengthy dependency chain from the Web App to the Data Layer?

  • How to debug unreleased COM references from managed code?

    - by Marek
    I have been searching for a tool to debug unreleased COM references, that usually cause e.g. Word/Outlook processes to hang in memory in case the code does not call Marshal.ReleaseCOMObject on all COM instances correctly. (Outlook 2007 partially fixes this for outlook addins, but this is a generic question). Is there a tool that would display at least a list of COM references (by type) held by managed code? Ideally, it would also display memory profiler-style object trees helping to debug where the reference increment occured. Debugging at runtime is not that important as being able to attach to a hung process - because the problem typically occurs when the code is done with the COM interface and someone forgot to release something - the application (e.g. winword) hangs in memory even after the calling managed application quits. If such tool does not exist, what is the (technical?) reason? It would be very useful for debugging a lot of otherwise very hard to find problems when working with COM interop.

  • JavaScript replace with callback - performance question

    - by Tomalak
    In JavaScript, you can define a callback handler in regex string replace operations: str.replace(/str[123]|etc/, replaceCallback); Imagine you have a lookup object of strings and replacements. var lookup = {"str1": "repl1", "str2": "repl2", "str3": "repl3", "etc": "etc" }; and this callback function: var replaceCallback = function(match) { if (lookup[match]) return lookup[match]; else return match; } How would you assess the performance of the above callback? Are there solid ways to improve it? Would if (match in lookup) //.... or even return lookup[match] | match; lead to opportunities for the JS compiler to optimize, or is it all the same thing?

  • "Primary Filegroup is Full" in SQL Server 2008 Standard for no apparent reason

    - by Anton Gogolev
    Our database is currently at 64 Gb and one of our apps started to fail with the following error: System.Data.SqlClient.SqlException: Could not allocate space for object 'cnv.LoggedUnpreparedSpos'.'PK_LoggedUnpreparedSpos' in database 'travelgateway' because the 'PRIMARY' filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. I double-checked everything: all files in a single filegroup are allowed to autogrow with a reasonable increments (100 Mb for a data file, 10% for a log file), more than 100 Gb of free space is available for the database, tempdb is set to autogrow as well with plenty of free HDD space on its drive. To resolve a problem, I added second file to the filegroup and the error has gone. But I feel uneasy about this whole situation. Where' the problem here, guys?

  • WPF, Image MouseDown Event

  • Setting a session variable in Global.asax causes AJAX errors

    - by Fly_Trap
    I'm getting a very peculiar problem with my asp.net application, it took me an age to track down but I still don't know what is causing this behaviour. If I set a session variable in the Application_PreRequestHandlerExecute event, then my external JavaScript files are ignored, and therfore causing a raft of errors. I have simplified the problem below. E.g. I have file called JScript.js containing the code: function myAlert() { alert("Hi World"); } And in my Default.aspx file I reference the js with the code: <script src="JScript.js" type="text/javascript"></script> And in the body onload event I call the myAlert() function: <body onload="myAlert()"> And finally in the Global.asax file: Private Sub Application_PreRequestHandlerExecute(ByVal sender As Object, ByVal e As EventArgs) HttpContext.Current.Session("myVar") = "MyValue" End Sub If you run the Default.aspx file you will see the js function isnt called, however, if you comment out the line of code Global.asax then the external js is called and the function executed when the page loads. Why is this?

  • Cross-Page communication in firefox extension

    - by OzBarry
    I have two tabs that my extension uses and I wanted to pass events back and forth between them. I've already developed a Google Chrome extension that does this via the background page api, but there doesn't seem to be an equivalent in firefox. I thought message-manager in the firefox extension docs would do the trick, but the documentation on the object is quite poor. I'd be just as happy with using one of the tabs to control the other if I can't directly import the ideas of a background page from google chrome api. Any help/guidance would be great.

  • FileNotFound exception when trying to write to a file

    - by Chris Knight
    OK, I'm feeling like this should be easy but am obviously missing something fundamental to file writing in Java. I have this: File someFile = new File("someDirA/someDirB/someDirC/filename.txt"); and I just want to write to the file. However, while someDirA exists, someDirB (and therefore someDirC and filename.txt) do not exist. Doing this: BufferedWriter writer = new BufferedWriter(new FileWriter(someFile)); throws a FileNotFoundException. Well, er, no kidding. I'm trying to create it after all. Do I need to break up the file path into components, create the directories and then create the file before instantiating the FileWriter object?
