  • how to set flex combobox cursor position

    - by crazy horse
    I have a combobox implementation as follows - Based on user input (min 2 chars) in the editable combobox, the data provider is refreshed and drop-down opened, showing different data sets as user input varies. Problem is that after drop-down opens, the cursor moves back to the beginning. So for instance, the user types in "ab", and wants to type in "c" to form the search string "abc". Due to the cursor re-setting its position to 0, the search string instead ends up as "cab". Here's what I tried already (doesn't work) : textInput.mx_internal::getTextField().setSelection(index, index); where index = length of user input. This selects text from index to index (which effectively un-selects text) and is supposed to place the cursor at the end. Any thoughts?

  • Refresh Windows Explorer in Win7

    - by Paja
    My program sets "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" value "Hidden". Hovewer I'm not able to refresh the explorer to take into account this change. I've tried: 1) SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, IntPtr.Zero, IntPtr.Zero);` 2) SHELLSTATE state = new SHELLSTATE(); state.fShowAllObjects = (uint)1; SHGetSetSettings(ref state, SSF.SSF_SHOWALLOBJECTS, true); 3) SendMessageTimeout(HWND_BROADCAST, WM_SETTINGCHANGE, SPI_SETNONCLIENTMETRICS, 0, SMTO_ABORTIFHUNG, 5000, ref dwResult); 4) SendMessage(HWND_BROADCAST, WM_COMMAND, 28931 /* Refresh */, 0); Nothing works. So what should I do? If I refresh Explorer myself with F5, then it works. Hovewer I would like some elegant solution, so it would refresh the display everywhere, even in OpenFile/SaveFile dialogs, which are currently open. I'm using C# .NET, Win7.

  • Scintilla custom syntax highlighting not working

    - by Nilbert
    I have a Scintilla control that I create in C#, and the syntax highlighting doesn't work. It sets the font correctly which tells me that the file is being loaded, but the syntax highlighting doesn't work at all: Scintilla r = new Scintilla(); r.Dock = DockStyle.Fill; r.ConfigurationManager.IsUserEnabled = true; r.ConfigurationManager.CustomLocation = "langs.xml"; r.ConfigurationManager.Language = "rb"; r.Margins[0].Width = 40; r.Indentation.UseTabs = true; r.Indentation.IndentWidth = 4; r.Indentation.ShowGuides = true; r.Indentation.TabIndents = true; r.Indentation.TabWidth = 4; r.Indentation.SmartIndentType = SmartIndent.Simple; and the configuration file is this: http://codepad.org/DAjCrlPT in langs.xml. (The code won't fit here.) Can someone tell me why this is not working?

  • Problem using Hibernate-Search

    - by KCore
    Hi, I am using hibernate search for my application. It is well configured and running perfectly till some time back, when it stopped working suddenly. The reason according to me being the number of my model (bean) classes. I have some 90 classes, which I add to my configuration, while building my Hibernate Configuration. When, I disable hibernate search (remove the search annotations and use Configuration instead of AnnotationsConfiguration), I try to start my application, it Works fine. But,the same app when I enable search, it just hangs up. I tried debugging and found the exact place where it hangs. After adding all the class to my AnnotationsConfiguration object, when I say cfg.buildSessionfactory(), It never comes out of that statement. (I have waited for hours!!!) Also when I decrease the number of my model classes (like say to half i.e. 50) it comes out of that statement and the application works fine.. Can Someone tell why is this happening?? My versions of hibernate are: hibernate-core-3.3.1.GA.jar hibernate-annotations-3.4.0.GA.jar hibernate-commons-annotations-3.1.0.GA.jar hibernate-search-3.1.0.GA.jar Also if need to avoid using AnnotationsConfiguration, I read that I need to configure the search event listeners explicitly.. can anyone list all the neccessary listeners and their respective classes? (I tried the standard ones given in Hibernate Search books, but they give me ClassNotFound exception and I have all the neccesarty libs in classpath) Here are the last few lines of hibernate trace I managed to pull : 16:09:32,814 INFO AnnotationConfiguration:369 -

  • IPhone SDK Default NSUserDefaults...

    - by Harry
    I have set up the user defaults to record a integer for a UISlider, the problem is that, if the user has only just installed the app then the integer is zero or NULL. Is there a way to detect if it = NULL with a integer? heres my code i have so far: -(void)awakeFromNib { NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; senset = [prefs integerForKey:@"senset"]; senset = sensitivity.value; } - (IBAction) setSens { senset = sensitivity.value; } - (IBAction) goBackopt { { NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; [prefs setInteger:senset forKey:@"senset"]; [prefs synchronize]; } } senset is the integer. i have tried this code, and it sets it to 25 on the first time, but then if i try and overwrite it, it wont work and keeps setting it to 25. :( if ( [prefs integerForKey:@"senset"] == NULL ) { senset = 25; } Please help :P Harry

  • Error connecting to online fossil repository after changing password.

    - by Toby Allen
    I set up a fossil repository on a shared hosting account I have. I created a perl script fossil.pl that points to a cloned repository that I put up on the webspace. I set all the correct permissions (755). When I go to fossil.pl I get the web ui. Everythings cool. However I'm having a problem with pushes and hoping someone could point me to a solution. When I clone a repository it sets a new password for me (Toby) in the new cloned repository. If I push to this repository online without changing the password it works fine, I can push up changes from my local machine to the online repository. However once I change the password for Toby (to something more easily remembered by me) I get the following error. Bytes Cards Artifacts Deltas Send: 1810 9 0 2 1Server Error: not authorized to write fossil: server says: not authorized to write Anyone know why this is happening? Anyone know how to fix it?

  • When would ShowDialog() return null?

    - by Joe White
    WPF's Window.ShowDialog method returns a nullable boolean. So does CommonDialog.ShowDialog. Now, I understand cases where these would return false (user clicked Cancel or pressed Esc), and when they would return true (code sets Window.DialogResult to true, probably in response to OK being clicked). But null? My first thought is that clicking the title bar's Close button might return null. But the docs state (and I confirmed by testing) that the title-bar Close button is treated as a Cancel. So when would Window.ShowDialog or CommonDialog.ShowDialog ever return null?

  • location.hash in an iframe scrolls the parent window

    - by Ben Clayton
    Hi all. I have a page with an iframe. Inside the iframe is code (that I can't change) that sets location.hash to the id of an element in the iframe window. This has the unwanted effect of scrolling my outermost browser window so that the top of the window touches the top of the iframe. This is quite annoying as I have a toolbar above the iframe that is vital to my app. Is there any way of preventing the setting of location.hash affecting the scroll position of the main window? Will preventDefault help me out here? Thanks!

  • Diophantine Equation

    - by lakshmi
    Show that it is possible to buy exactly 50, 51, 52, 53, 54, and 55 McNuggets, by finding solutions to the Diophantine equation. You can solve this in your head, using paper and pencil, or writing a program. However you chose to solve this problem, list the combinations of 6, 9 and 20 packs of McNuggets you need to buy in order to get each of the exact amounts. Given that it is possible to buy sets of 50, 51, 52, 53, 54 or 55 McNuggets by combinations of 6, 9 and 20 packs, show that it is possible to buy 56, 57,..., 65 McNuggets. In other words, show how, given solutions for 50-55, one can derive solutions for 56-65.python

  • Fastest way to calculate an X-bit bitmask?

    - by Virtlink
    I have been trying to solve this problem for a while, but couldn't with just integer arithmetic and bitwise operators. However, I think its possible and it should be fairly easy. What am I missing? The problem: to get an integer value of arbitrary length (this is not relevant to the problem) with it's X least significant bits sets to 1 and the rest to 0. For example, given the number 31, I need to get an integer value which equals 0x7FFFFFFF (31 least significant bits are 1 and the rest zeros). Of course, using a loop OR-ing a shifted 1 to an integer X times will do the job. But that's not the solution I'm looking for. It should be more in the direction of (X << Y - 1), thus using no loops.

  • What are jQuery best practices regarding Ajax convenience methods and error handling?

    - by JonathanHayward
    Let's suppose, for an example, that I want to partly clone Gmail's interface with jQuery Ajax and implement periodic auto-saving as well as sending. And in particular, let us suppose that I care about error handling, expecting network and other errors, and instead of just being optimistic I want sensible handling of different errors. If I use the "low-level" feature of $.ajax() then it's clear how to specify an error callback, but the convenience methods of $.get(), $.post(), and .load() do not allow an error callback to be specified. What are the best practices for pessimistic error handling? Is it by registering a .ajaxError() with certain wrapped sets, or an introspection-style global error handler in $.ajaxSetup()? What would the relevant portions of code look like to initiate an autosave so that a "could not autosave" type warning is displayed if an attempted autosave fails, and perhaps a message that is customized to the type of error? Thanks,

  • Disable selected automated tests at runtime

    - by squig
    Is is posable to disable selected automated tests at runtime? I'm using VSTS and rhino mocks and have some intergation tests that require an external dependancy to be installed (MQ). Not all the developers on my team have this installed. Currently all the tests that require MQ inherit from a base class that checks if MQ is installed and if is not sets the test result to inconclusive. This works as it stops the tests from running, but marks the test run as unsuccseessful and can hide other failures. Any ideas?

  • How to add flags to RC.EXE through QMake .pro makefiles

    - by Hernán
    I've the following definition in my .pro file: RC_FILE = app.rc This RC file contains a global include at the top: #include "version_info.h" The version_info.h header is on a common header files directory. Since RC.EXE takes INCLUDE environment variable in consideration, according to MS documentation, my build process batch sets up that accordingly: SET INCLUDE=%PROJECTDIR%\version;%INCLUDE% ... QMAKE project.pro -spec win32-msvc2008 -r CONFIG += release This works perfect as RC seems to read that INCLUDE var so the "version_info.h" file is including on every RC file properly. The problem is when I generate a VS solution (or Import it through the VS Addin). The RC invocation does not contain any /I flag (as I expect) but does not read any INCLUDE variable, even when I've setup through system 'environment variables' dialog in XP. So I'm stuck with this problem, with two alternatives I could not get to work: Make VS RC.exe invocation honour the INCLUDE variable (didn't work either as user or system variable). Force QMAKE to pass /I flag to RC invocation, and get that /I flag imported into the project settings (Resource Compiler properties). Thanks in advance.

  • Cross domain cookie reading/setting cross browsers

    - by Rac123
    I know there are already a few threads available here on this subject but I want others' opinion on this. There are two ways to set/read the cross domain cookies: Creating IFrame on A.com pointing to a page on B.com which creates the cookie and pass that information by creating another IFrame on B.com side pointing to A.com, either using window.name or in location.href.hash A.com page makes a XHR/JSONP call to B.com web service/page that has the following headers and it also sets up the cookie and returns the value. AddHeader("p3p", "CP=\"IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT\"") As we don't have postMessage available across all the browsers, I believe we have to go with one of the cases mentioned above. My question is which is a better way (cleaner) and why to implement for cross browser. Using any other JS framework is out of scope of this discussion. If there's another better way, please mention here! Thank you for your intelligent input in advance! :)

  • Navigation bar's buttons tint color sometimes not set

    - by Felipe
    Refer to the following, short video: http://screencast.com/t/cmnsqVTh The problem is with the color of a navigation bar's back button. The first time I load the app, the navigation bar + its buttons have the default color. I then push a view controller on the stack, and when the new view loads (in the viewDidLoad method), it sets the navigation bar's tint color to pink. The nav bar's buttons are also pink as expected. I then press the back button, and the view is popped from the stack. On the root view controller's viewWillAppear method I set the tint color back to nil so that it's the default color again. The navigation bar looks as expected. However if I push the view controller on the stack yet again, the navigation bar's tint color is pink, but the back button's color is the default light blue. Hope that was understandable. So what's the cause of the problem?

  • gwt rounded panel (standards based widget akin to DecoratorPanel)

    - by brad
    I'm trying to write an app that uses rounded corners for framing the app. I've found a package on google code that has a RoundedLinePanel and it seems to work... kind of. I'm wondering a few things. Is this what people are using for creating divs with round corners in GWT? The release notes say it hasn't changed in almost a year. Also, I can't seem to set a fixed height of this div (setHeight sets it on the wrapper div, not the inner one). so it's not useful to me as I have a fixed height app. Finally, if anyone can suggest a better mechanism for creating rounded corner divs in GWT I'm all ears.

  • Manual testing Vs Automated testing

    - by mgj
    Respected all, As many know testing can be mainly classified into manual and automated testing. With regard to this certain questions come to mind. Hope you can help... They include: What is the basic difference between the two types of testing? What are the elements of challenges involved in both manual and automated testing? What are the different skill sets required by a software tester for manual and automated testing respectively? What are the different job prospects and growth opportunities among software testers who do manual testing automated testing respectively? Is manual testing under rated to automated testing in anyway(s)? If yes, kindly specify the way. How differently are the manual testers treated in comparison to automated testers in the corporate world?( If they truly are differentiated in any terms as such ) I hope you can share your knowledge in answering these questions..

  • TelerikProfileProvider with custom Membership Provider

    - by Larsenal
    I've setup two membership providers: my custom provider and the Sitefinity provider. My custom membership provider is set as the default. I want to use Sitefinity's Profile provider for both sets of users. However, the profile provider only seems to work for the users that I pull out of the Sitefinity membership provider. After poking around with Reflector a bit, it seems that the Telerik Profile Provider assumes that the username exists in its own DB. User userByName = this.Application.GetUserByName(userName); if (userByName != null) { // magic happens here... } All the magic only happens if it was able to retrieve the user locally. Seems to violate the principles of the providers. Shouldn't I be able to arbitrarily add properties to any user regardless of the membership provider? (I've also posted this on the Sitefinity forum, but haven't got a response yet. SO has spoiled me. I've come to expect an answer in minutes, not days.)

  • SVN problems after migration with CVS2SVN

    - by Bjorn C
    We´ve migrated from CVS on AIX to SVN on Linux via CVS2SVN. The migration seems to have went well but when working in SVN we get a lot of Tree Conflicts that doesn´t seem to be conflicts at all? Looking at the revision graphs, one can see that the graph for e.g. trunk and a branch isn´t the same, i.e. they contain different sets of revisions of the file. Either of the 3 ways to resolve this conflict when merging in TortoiseSVN leaves the revision graphs separate, they cannot be "melted" together. Could it be that CVS2SVN didn´t understand that a file in different branches is the same even if the file system path is the same? Anyone who has experienced this? Thanks, Bjorn

  • How to model "target day" in UML Classdiagrams

    - by Tobiask
    Hi there, I want to describe the following situation in an UML Classdiagram: A day, on which a newspaper is send to a customer. This day could be sth. like "every friday" or "every first day of a month". My idea to represent this in a UML Classdiagram: -targetDay:Integer -targetDayGrid:Enumeration targetDay would be sth. like "1" (for monday) oder "5" (for friday) or it could be "1" for the first day of the month or "10" for the 10th day of the month. targetDayGrid is an enum: weekly, monthly. So the enum sets the semantic meaning of the number in targetDay. I´m not happy with this, do you know any other solution to represent my problem? Or do you think my solution is okay?

  • Better Alternative to Case Statement

    - by Kyle Rozendo
    Hi All, I currently have a switch statement that runs around 300 odd lines. I know this is not as giant as it can get, but I'm sure there's a better way to handle this. The switch statement takes an Enum that is used to determine certain properties that pertain to logging. Right now the problem sets in that it is very easy to leave out an enumeration value and that it will not be given a value as it is not in the switch statement. Is there an option one can use to ensure that every enumeration is used and given a custom set of values it needs to do its job? Thanks, Kyle

  • Comparison of Code Review Tools/Systems

    - by SytS
    There are a number of tools/systems available aimed at streamlining and enhancing the code review process, including: CodeStriker Review Board, code review system in use at VMWare Code Collaborator, commercial product by SmartBear Rietveld, based on Modrian, the code review system in use at Google Crucible, commercial product by Atlassian These systems all have varying feature sets, and differ in degrees of maturity and polish; the selection is a little bewildering for someone who is evaluating code review systems for the frist time. Some of these tools have already been mentioned in other questions/answers on StackOverflow, but I would like to see a more comprehensive comparison of the more popular systems, especially with respect to: integration with source control systems integration with bug tracking systems supported workflow (reviews pre/post commit, review or contiguous/non-contigous revision ranges, etc) deployment/maintenance requirements

  • CruiseControl failing view compilation with Asp.net MVC 2 RTM

    - by Robert Koritnik
    Tehnologies: - CruiseControlNet - Asp.net MVC 2 RTM - enabled view compilation The problem is UrlParameter.Optional setting. I can't seem to make it work when I use this setting inside a view. When I compile inside Visual Studio, everything works fine, but when CCNet uses MSBuild to compile it it fails with following error: errorCS0103: The name 'UrlParameter' does not exist in the current context pointing to the line inside my view where this parameter is set on: Html.RenderAction(...) that sets certain route parameter(s) to optional. I tried adding <%@ Assembly name="System.Web.Mvc" %> at the top of my view, but it didn't work either. It works of course when I disable view compilation, but that's not really an option. And I also don't want to set my optional parameters to string.Empty. Anyone has any hint on this?

  • Enum.values() vs EnumSet.allOf( ). Which one is more preferable?

    - by Alexander Pogrebnyak
    I looked under the hood for EnumSet.allOf and it looks very efficient, especially for enums with less than 64 values. Basically all sets share the single array of all possible enum values and the only other piece of information is a bitmask which in case of allOf is set in one swoop. On the other hand Enum.values() seems to be a bit of black magic. Moreover it returns an array, not a collection, so in many cases it must be decorated with Arrays.asList( ) to be usable in any place that expects collection. So, should EnumSet.allOf be more preferable to Enum.values? More specifically, which form of for iterator should be used: for ( final MyEnum val: MyEnum.values( ) ); or for ( final MyEnum val: EnumSet.allOf( MyEnum.values ) );
