• How can I open another tab in the browser from the Code Behind [duplicate]

  - by Daniel Powell

  This question already has an answer here: Response.Redirect to new window 18 answers I have an ASP.Net project that I am working on that involves opening another tab in the browser from the vb.net (code behind). I have tried to use the WebBrowser control to open the new tab as well as tried to use the Script manager however I have not been able to open the new tab. The button I am using is a custom button in a DevExpress GridView, and I am handling its click with this code: Private Sub ASPxGridView2_CustomButtonCallback(sender As Object, e As DevExpress.Web.ASPxGridView.ASPxGridViewCustomButtonCallbackEventArgs) Handles ASPxGridView2.CustomButtonCallback If e.ButtonID <> "customButton" Then Return End If Dim neededID = ASPxGridView2.GetRowValues(e.VisibleIndex, "target") Dim id = CStr(neededID) Dim url = ("targetPage.aspx" + "?ID=" + id) Dim wb As WebBrowser wb.Navigate(url,True) End Sub I'm not sure why this would not work, any suggestions as to how I should open a new browser tab with or without the WebBrowser works for this project. EDIT: I cannot use javascript with this ASPxGridview So I need an answer that doesn't involve modification to the javascript except through the vb.net code behind

• Why does my UI controls work on iPhone but not iPad?

  - by Andrew

  I have an iPhone app, which consists of a table view containing various custom UITableViewCells, with UISlider and UISwitch controls. When running the app on the iphone, I can move the slider and switches contained in each of the table cells. When I run the same app on the iPad. I can not. None of the controls within the table view will respond to touches. I have checked 'User Interaction Enabled' within the Interface Builder. Anybody got any suggestions of where I should be looking for the cause of different behavior between the iPhone and iPad, in respect to UIControls.

• How can I create a profiler GUI in WPF?

  - by thehan

  I am looking to create a task profiler in WPF with an UI similar to the one of incredibuild. Eg, timed tasks appear as strips on their respective line. Have a look at: http://baoz.net/wp-content/2009/06/ib1.png to see what I mean. I am unsure what the best way to tackle this problem is? Should I override the Panel class creating a custom layout panel for this or might there be an existing control/library out there that can fit my needs. I have so far had a look at various charting controls but am unsure of weither they can be tweaked to achieve this behaviour or not. I am really hoping for someone who has been using WPF for a while to help me narrow down my search. It is not exactly easy to know what to google for either :)

• Is this a secure way to structure a mysql_query in PHP

  - by Supernovah

  I have tried and tried to achieve an SQL injection by making custom queries to the server outside of firefox. Inside the php, all variables are passed into the query in a string like this. Note, by this stage, $_POST has not been touched. mysql_query('INSERT INTO users (password, username) VALUES(' . sha1($_POST['password']) . ',' . $_POST['username'] . ')); Is that a secure way to make a change?

• How can i get the selected option name or id of a select element using jQuery

  - by bill

  Hi All, i have a "questionairre" that is made up of a series of select boxes. i need to use two properties in the options. For each selected option i need the value (which i know how to get and is working fine) but i also need to store an additional value which represents the id of the specific option in a DB. One solution would be to put the two values in the "value" property and parse it out.. but if there is some other property i can use that might be easier and clearer.. can i add a custom property?? like databaseId that could be accessed with jQuery? thanks for ANY suggestions.

• New records added to DataGridView aren't displayed

  - by Ross

  I have a custom Order class, groups of which are stored in List<Order> and a DataGridView. I think the problem is in my implementation so here's how I'm using it: In the form enclosing DataGridView (as OrdersDataGrid): public partial class MainForm : Form { public static List<Order> Orders; public MainForm() { // code to populate Orders with values, otherwise sets Orders to new List<Order>(); OrdersDataGrid.DataSource = Orders; } Then in another form that adds an Order: // Save event public void Save(object sender, EventArgs e) { Order order = BuildOrder(); // method that constructs an order object from form data MainForm.Orders.Add(order); } From what I can tell from the console this is added successfully. I thought the DataGrid would be updated automatically after this since Orders has changed - is there something I'm missing? The DataGrid accepts the class since it generates columns from the members.

• VS 2010 SQL Update for SQL Statement

  - by Mike Tucker

  Please bear with me as I'm just beginning to learn this stuff. I have a VS 2010 Web project up and I'm trying to understand how I can make a custom UpdateCommand (Because I chose to write my own SQL statement, I do not have the option for VS 2010 to auto generate an update command for me.) Problem is: I don't know what the UpdateCommand should look like. Here is my Select: SELECT * FROM Dbo.MainAsset, dbo.Model, dbo.Hardware WHERE MainAsset.device = Hardware.DeviceID AND MainAsset.model = Model.DeviceID Which, VS 2010 turns into: SELECT MainAsset.pk, MainAsset.img, MainAsset.device, MainAsset.model, MainAsset.os, MainAsset.asset, MainAsset.serial, MainAsset.inyear, MainAsset.expyear, MainAsset.site, MainAsset.room, MainAsset.teacher, MainAsset.FirstName, MainAsset.LastName, MainAsset.Notes, MainAsset.Dept, MainAsset.AccountingCode, Model.Model AS Hardware, Model.pk AS Model, Model.DeviceID, Hardware.Computer, Hardware.pk AS Expr3, Hardware.DeviceID AS Expr4 FROM MainAsset INNER JOIN Hardware ON MainAsset.device = Hardware.DeviceID INNER JOIN Model ON MainAsset.model = Model.DeviceID How would I approach updating one column, say "MainAsset.site" if that's changed in the Gridview DDL? Any help constructive help would be appreciated. Thank you.

• Creating a Pop up and setting its view state before it displays

  - by theringostarrs

  Hi, I am a beginner developer in Flex, and I have been using viewstates lately. I had a couple of custom popup titlewindow components that are initialized using: PopUpManager.createPopUp(this, ContentCreate, true); They both contain view states already, and are very similar so I wanted to combione them into one popup titlewindow and change view state on initialisation of the popup to either the Create version of the popup or the Update. I thought I was being smart haha, but I realized soon after refactoring my code that, I as far as I know I can't pass parameters to the popup to indicate which state I want, if it is created using the PopUpManager. Does anyone know how to pass parameters to the PopupManager, or create the ContentCreate component(TitleWindow) in mxml or code so I can specify the view state?

• Global Import/using Aliasing in .NET

  - by Josh Stodola

  Using import aliasing in a single class, we can reference class library namespaces by assigning our own custom alias like this: ' VB Imports Db = Company.Lib.Data.Objects // C# using Db = Company.Lib.Data.Objects; And then we are able to reference the classes inside of Company.Lib.Data.Objects by using the Db alias that we assigned. Is it possible to do this at the global level so that the alias is applied to the entire solution instead of the given file? Currently, we are working with web applications, so I was hoping we could add something to web.config, but I am also interested in whether or not this is possible with windows forms, console apps, and/or class libraries.

• C# new class with only single property : derive from base or encapsulate into new ?

  - by Gobol

  I've tried to be descriptive :) It's rather programming-style problem than coding problem in itself. Let's suppose we have : A: public class MyDict { public Dictionary<int,string> dict; // do custom-serialization of "dict" public void SaveToFile(...); // customized deserialization of "dict" public void LoadFromFile(...); } B: public class MyDict : Dictionary<int,string> { } Which option would be better in the matter of programming style ? class B: is to be de/serialized externally. Main problem is : is it better to create new class (which would have only one property - like opt A:) or to create a new class derived - like opt B: ? I don't want any other data processing than adding/removing and de/serializing to stream. Thanks in advance!

• Can an Oracle user get a list of its own running sessions without access to v$session?

  - by Nick Pierpoint

  I have an application that runs a process and I only want one process to run at a time. Some options are: Use an object lock to prevent subsequent processes running. This would be fine, but I want the calling session to return immediately and not wait for the running session to complete. Use a custom Y/N to set whether a process is running or not. I set a "Y" flag at the start of the process and set it to "N" when it finishes or fails. Also fine but feels like I'm re-inventing the wheel and doesn't feel like the way to go. It also falls short if the running session is killed as the flag stays at "Y". Use dbms_application_info.set_module This approach seems the most robust, but if I'm to know there's an existing running process I think I need to be able to query v$session and I don't want this application to have such wide access. Any ideas?

• Authenticating model - best practices

  - by zerkms

  I come into ASP.NET from php so the reason why i ask my question is because it's totally different nature of how application works and handles requests. well, i have an exists table with user creditians, such as: id, login, password (sha hashed), email, phone, room i have built custom membership provider so it can handle my own database authentication schema. and now i'm confused, because User.Identity.Name contains only user's login, but not the complete object (i'm using linq2sql to communicate with database and i need in it's User object to work). at php applications i just store user object at some static method at Auth class (or some another), but here at ASP.NET MVC i cannot do this, because static member is shared across all requests and permanent, and not lives within only current request (as it was at php). so my question is: how and where should i retrieve and store linq2sql user object to work with it within current and only current request? (after request processed successfully i expect it will be disposed from memory and on next request will be created again). or i'm following totally wrong way?

• embedded wpf textbox does not accept input

  - by pro3carp3

  I put a wpf textbox inside a combobox to allow the user to enter a custom setting. I can read the keypress in the keydown event, but the text in the textbox does not change.

• Chaining Animations (iPhone / MonoTouch)

  - by ifwdev

  I'm trying to slide some (custom) tab-like buttons into view. I don't want them all to move at the same time. Also, they shouldn't move one at at time (where one slides after the other finishes). I want each button to begin sliding slightly after the previous. Preferably it would happen on a curve but just a fixed .1 second offset would be alright too. Monotouch or Obj-C code is fine. I'm thinking there is something in the APIs for animating groups of items like this. Hopefully, at least...

• 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?

• C# Object Array CopyTo links both arrays' values?

  - by Dutchie432

  Okay, I have what I think is a simple question.. or just a case of me being a C# beginner. I have an array of custom objects (clsScriptItem) that I am populating from a database. Once the items are loaded, I want to back them up to "backup" array so I can revert the information back after changing the main array. However, when I use CopyTo to copy the array and then alter the original array, the backup array is also being altered... I though CopyTo merely copied values + structure from one array to another. private void backupItems() { lastSavedItems = new clsScriptItem[items.Length]; items.CopyTo(lastSavedItems, 0); //items[0].nexts[0] is 2 //lastSavedItems[0].nexts[0] is 2 items[0].nexts[0] = "-1"; //items[0].nexts[0] is -1 //lastSavedItems[0].nexts[0] is also -1 } How do I backup this data without having the two arrays be 'linked'??

• Distributing cpu-bound compression jobs to multiple computers?

  - by barnaby

  The other day I needed to archive a lot of data on our network and I was frustrated I had no immediate way to harness the power of multiple machines to speed-up the process. I understand that creating a distributed job management system is a leap from a command-line archiving tool. I'm now wondering what the simplest solution to this type of distributed performance scenario could be. Would a custom tool always be a requirement or are there ways to use standard utilities and somehow distribute their load transparently at a higher level? Thanks for any suggestions.

• Connecting to device behind firewall

  - by tim

  I have a wpf app that needs to communicate(exchange data) with a custom designed device (we can modify the code for the device). Do I have any options to connect to the device if it is behind a firewall via http? I was hoping there would be a method where the admin would not have to forward any specific ports or do anything on his end. I assume the issue is how would I address the device from my app. I know SOAP over SMTP is one option. Is another option where the device could chatter out to my application via http?

• How to raise an event when another event is raised?

  - by WulfgarPro

  Hi, I have an application that handles the OnQuit event of another running application. I would like to raise an additional (custom) event when the OnQuit event is handled. How could I implement such an event? My OnQuit handler is like so: private void StkQuit() { _stkApplicationUi.OnQuit -= StkQuit; Marshal.FinalReleaseComObject(_stkApplicationUi); Application.Exit(); } The reason I require the additional event is so that I can tell my View layer that the application has exited. If this is not the correct way, what would be better? WulfgarPro
