• Window opened from DataGrid is placed in background

  - by 0xddr

  One column in DataGrid looks like that: <DataTemplate> <StackPanel> <Image MouseDown="OpenWindow" /> <Image MouseDown="func2"/> </StackPanel> </DataTemplate> In OpenWindow window is opened: it starts opening in foreground (in front of the window with DataGrid), but when creating UI ends it is placed behind window with DataGrid, which is not expected behavior. When I changed Image to Button and MouseDown to Click everything works as it should (opened window is placed in front of the one with DataGrid).

• How to add the UAC shield icon to program that still must target XP?

  - by bsruth

  I have a program that still must target Windows XP (_WIN32_WINNT 0x501), as most of our customers still use XP. However, we have been shipping Vista for a while, and are now pushing Windows 7 upgrades. For the software to work correctly on the newer OSs, there are a couple operations that require UAC elevation. I have the elevation code working, but would like to have the UAC icon present on the buttons that launch the UAC process. Unfortunately, all of the options defined in Microsoft's UAC UI document require _WIN32_WINNT 0x600 or newer. Is there any way to get the appropriate UAC icon (Vista and 7 use different ones) to show on the button while still being able to target XP (where no icon will be shown)? I'm using C++, but may be able to adapt a .NET solution.

• How can I improve my programming skills with out a computer (or reading material)?

  - by Tom Duckering

  Given the recent and continued chaos with grounded flights and folks stuck in airports, and what not, I'm wondering if anyone has any suggestions for activities that would help sharpen and develop a progammer's mind. The constraints are: Laptop is out of battery and there are no free sockets. You're bored of the book you're reading or you have none with you. Reasonable resources such as a pen and pad of paper are available. Rules can be bent within reason. As daft examples, things I have thought about are: How I might optimise the boarding of a plane. How I might improve the UI of a departure board.

• Anyway to get a value similar to @@ROWCOUNT when TOP is used?

  - by cfeduke

  If I have a SQL statement such as: SELECT TOP 5 * FROM Person WHERE Name LIKE 'Sm%' ORDER BY ID DESC PRINT @@ROWCOUNT -- shows '5' Is there anyway to get a value like @@ROWCOUNT that is the actual count of all of the rows that match the query without re-issuing the query again sans the TOP 5? The actual problem is a much more complex and intensive query that performs beautifully since we can use TOP n or SET ROWCOUNT n but then we cannot get a total count which is required to display paging information in the UI correctly. Presently we have to re-issue the query with a @Count = COUNT(ID) instead of *.

• Capture IP packets on Dialup connection - Windows 7

  - by Assaf Levy

  Our product utilizes (the wonderful) Winpcap to capture ip packets from all devices with an IP address and analyze them in real time. Unfortunately, we discovered that it does NOT capture any packets on dialup (e.g. PPP) connections on Windows 7, and that there are no near-term plans for enabling this (1). So we need something else. Microsoft Network Monitor and Windows Packet Filter are two options that surfaced during a bit of googling, but before delving into research I wanted to ask the experienced: what are out options, given the following requirements: Capture all in/outbound IP packets on the machine. Complete background processing - no UI should be involved. Support Windows Vista / 7. Performance (user should not feel the difference). Thanks in advance.

• c++ - QListWidget

  - by user1889459

  I created a working QListWidget with multiple items, but I can't figure out how to make it user-friendly. It looks like this: 1000 1001 1002 ... But I want it to look like this, where firt 4 numbers have a meaning, while all the rest info is just for user. 1000 Name LastName and some other helpful info 1001 tom jeff smallville 1002 ming vase, 1992 ... For example, this line fotoId = ui->devices->currentItem()->text().toInt(); should give me same result in both cases.

• Apply CSS class to invalid controls on web form

  - by user137639

  I need to apply a css class to invalid controls on a web form. I'd like to make it a resusable class. This is what I have so far: public class Validation { public static void ApplyInvalidClass(Page page, string className) { foreach (System.Web.UI.WebControls.BaseValidator bv in page.Validators) { if (!bv.IsValid) { Control ctrl = page.FindControl(bv.ControlToValidate); if (ctrl != null) { if (ctrl is TextBox) { TextBox txt = ctrl as TextBox; txt.CssClass = "invalid"; } if (ctrl is DropDownList) { DropDownList ddl = ctrl as DropDownList; ddl.CssClass = "invalid"; } if (ctrl is CheckBox) { CheckBox cb = ctrl as CheckBox; cb.CssClass = "invalid"; } if (ctrl is HtmlGenericControl) { HtmlGenericControl html = ctrl as HtmlGenericControl; html.Attributes.Add("class", className); } } } } } } The problem is what I call this on a .Net user control, I guess because I'm passing in Page, page.FindControl(bv.ControlToValidate) is always null. Is there a better way to do this?

• How does the WP7 Pivot control dynamically load pivot items?

  - by mztan

  IIRC, the Pivot control only loads a child PivotItem if it is the currently shown child. I would then guess that the previously seen child is also somehow unloaded, presumably still stored in memory, but hidden from the UI. What I'm wondering is, how does the Pivot control dynamically load/unload a child control, and can that behavior be imitated within a custom UserControl? As for unloading, is it as simple as collapsing the previous child's visibility, or is something trickier going on? That is to say, supposing I use my own UserControl like: <my:CustomUserControl> <TextBlock x:Name="_textBlock" Text="wait for it ..." /> </my:CustomUserControl> Normally, the child TextBlock is instantiated when the surrounding PhoneApplicationPage is instantiated, via InitializeComponent and all that. Is there any way to postpone this behavior and load the child programmatically?

• Creating a System.Windows.Controls.Image throws an exception - how do I use the dispatcher to instan

  - by Scott Whitlock

  I'm running my unit tests on a piece of code that does the following in the test: Assert.IsNotNull(target.Icon); Inside the getter for the Icon property, I'm doing this: System.Windows.Controls.Image img = new System.Windows.Controls.Image(); That's throwing this exception: System.InvalidOperationException : The calling thread must be STA, because many UI components require this. I understand what that means, and I understand that I need to use the Dispatcher, but I'm a bit confused about how or why... this is a property of my ViewModel and I don't get any of these exceptions when running the application. Other info: this only started failing when I upgraded to .NET 4.

• didSelectRowAtIndexPath being called after viewDidLoad of the called view

  - by Serguei Fedorov

  I am trying to pass variables over to the new view. I have the following code: appDelegate *dataCenter = (AppDelegate*)[[UIApplication sharedApplication] delegate]; dataCenter.myVariable = [array objectAtIndex:indexPath.row]; in the didSelectRowAtIndexPath of the calling view. However, the issue that I have is that this variable is empty in the vewDidLoad function of the next view, simply because it fired off BEFORE the didSelectRowAtIndexPath of the calling view. I am using storyboard to link the views together. Both are UITableView. If I hit back and then reselect the table element it is then set, granted that by the time I hit back and then selected again, the variable got set. Is there any way to for the order of execution? I really don't want to do UI view switching on the back end. Any help is greatly appreciated!

• Casting to specific asp.net page type

  - by DEH

  I have an asp.net page with a code-behind class definition as follows: public partial class examplepage : System.Web.UI.Page I'd like to set a public property within the page that I can reference from other classes. My understanding is that if I cast to examplepage then I should be able to get at the public property that is specific to example page, as in: string test=((examplepage)HttpContext.Current.Handler).propertyX; However, when I try casting as above the compiler does not recognise examplepage. Can anyone tell me how I can cast? I have no specific namespaces defined. Thanks

• ANY material writen in/for DELPHI around the graphics topic?

  - by José Eduardo

  Does anyone knows ANY material writen in/for DELPHI around the graphics topic? Planning to build a software for medical imaging processing . Thinking in 3D UI to absorve the power of nvidias GTX graphics card, and some real-time 2D processing integrated with high-end scanners. Please dont take this as a "rant" but, we have zillions of C++ books writen about that kind of topic and nothing for pascal/delphi. If you have some experience could you comment about that? Is it better to learn c++, to have access to that material? Can i go with delphi? I have experience with delphi, but none with graphics... And i have a deadline... Thanks.

• Spring MVC managing multiple views with single controller

  - by Sudhir

  I am trying to implement order management module. There are different order types (approximately about 15). Each order has a seperate view. But the actions performed on UI are same irrespective of order type. Below is the structure of my DTO abstract class Order abstract class SecurityOrder extends Order abstract class TermDepositOrder extends Order ..... ..... ..... I am trying to implement a single controller capable of managing all views. Something similar to the one below: @Controller public class OrderController<F extends Order> { public F validate(F order) { } public F insert(F order) { } } I am not sure how spring mvc would be able to map request parameters properly to the order instance as it doesn't know which order instance to populate. Is it possible to achieve this with single controller or should I go with a controller for each order type and duplicate same code across all controllers?

• How to use condition in a TestGen4Web script for a child popup window?

  - by GotoError

  I have TestGen4Web script for automating testing on a web-based user interface that has a popup window (hey i didn't write that ui..). In order to write a complete test script that branches the flow based on the some presence of some content in the popup window, I need to write a simple if condition that does something like if document.getElementById("xyz").value - that will run on the popup window and not the parent window. Any ideas on how to accomplish this? currently, the condition fails because it runs on the parent window. Also, how to extract some text from the dom and spit it out to a file at the end of the test?

• Emulating Preference look/feel with LinearLayout

  - by colinodell

  I really like the look and feel of the Preference UI items and want to replicate that in my application. Basically I've got an Activity with a couple LinearLayouts set to be focusable. When they are focused, I want them to turn green (like Preferences do). Any idea how to apply that style to my LinearLayouts? Note: The LinearLayouts are essentially going to be clickable 'buttons' to launch a separate activity. They are NOT actual preferences or buttons, although they need to look/act similar to them.)

• How would you code this: Grid-breaking shapes

  - by BeachRunnerJoe

  I'm a person that learns best from example. Currently, I'm diving into the field of Web Development after fifteen years of developing desktop apps. I'm still getting used to all the web technologies used for developing modern web sites and everywhere I look, I see cool little UI elements and question how they're implemented. So I thought I'd ask you, the web experts...the wexperts :) What are some straight forward or creative ways you could code this grid-breaking arrow... The basic layout for this page looks like... What would the html/css code look like? Would you split the image into multiple images or could you use a single image? I'm sure this is a really simple concept and it completely boggles me. I'm sorry if this is a strange question, remember I'm a noob! :) Thanks in advance for all your help! Here's a link to the original tutorial where I found these images

• GWT HTMLTable colaspan feature

  - by Sanjay

  Hello all I am using HTMLTable of import com.google.gwt.user.client.ui.HTMLTable I instantiated it like below: HTMLTable table = new Grid(rows, col); Number of rows and columns are decided by the user input. Now I want to used colspan for the specific rows of the table. One way to this is apply css to the that specific row.But problem with this is that Number of column to span are decided by the user input, i.e It may vary every time. So by using css it is something like making it static. So I want to know the way through which I can do colspan on the rows of the table. and Number of column to span is different every time. Thanks in advance

• Where are good examples of Web applications built for skilled and intense use?

  - by ProfK

  I have spent most of my development career writing backend code, or front-end apps for used as daily business tools, by at least semi-skilled staff, e.g. order-tracking, sales capture, etc. That those I helped build peformed their tasks well is comfort enough, but I am still seeking excellence in the building of these kind of apps, versus the more trendy emphasis on slow and sensual interpersonal relationships with the UI. Can anyone recommend reading on this type of application (LOB?) on the web today? Any available examples to study?

• Assigning data to an <li> element?

  - by user246114

  Hi, I am generating some list items as a result of a search, and I want to attach some data to each list element from the search (possibly a bad idea to merge ui and data), but now curious about it. I am doing this: var element = $("<li>Hello</li>); element.mydata = "foo"; element.appendTo("#panelParent"); so I'm just assigning my stuff to element.mydata. My click handler reports that no such data exists for the element when clicked: $('#panelParent').delegate('li', 'click', function() { // this.mydata is undefined. }); where did it go to? I could keep the data external to the a list item element, was wondering if there's a convenient way like this to just keep it bound though? Thanks

• drupal + i18n - how to send the currently selected locale to javascript?

  - by egarcia

  I've got a multi-lingual Drupal 6 installation. The multi-language is provided by the i18n module. I'm displaying some date pickers using jquery ui's datepicker. I'd like to localize those datepickers too (so when the page being shown is English, they show 'mon tue wed ...' but when the page is in Spanish they show 'lun mar mi ...'). My problem is: I don't know how to send the currently selected locale to javascript. The closest thing I could find was the javascript Drupal.locale object. However that object doesn't seem to have a 'locale name'.

• Converting table based layout into a div/css based one.

  - by nimo9367

  I'm supposed to rewrite the UI for a rather large web application. The thing is that the layout is completely based on tables and if I could somehow, semi automatically, convert the tables into divs it would save me a huge amount of time. What are the best practices when doing something like this? Is this a good idea at all? The application use layout files (containing something similar to helpers) that are parsed into html at runtime and the application itself also output html at specific places. So the work will consist of converting these helpers and the htmloutput code within the application.
