  • Long key press handling in android 1.5

    - by Kaillash
    Hi, I want to handle key press and long key press for the key code KEYCODE_BACK(back button). can any one suggest me how to do this in android 1.5(API level 3). Here is the code. public boolean onKeyDown(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_BACK) { if(event.getRepeatCount()==0) { // normal key press // But problem is, this code is hitting for long press also, how to avoid this } else { // Long key press //Do something here } // Always consume back key event by returning true //so that default behavior of back is overrided return true; } return super.onKeyDown(keyCode, event); }

  • How to force Maven to download maven-metadata.xml from the central repository?

    - by Alceu Costa
    What I want to do is to force Maven to download the 'maven-metadata.xml' for each artifact that I have in my local repository. The default Maven behaviour is to download only metadata from remote repositories (see this question). Why I want to do that: Currently I have a remote repository running in a build machine. By remote repository I mean a directory located in the build machine that contains all dependencies that I need to build my Maven projects. Note that I'm not using a repository manager like Nexus, the repository is just a copy of a local repository that I have uploaded to my build machine. However, since my local repository did not contain the 'maven-metadata.xml' files, these metadata files are also missing in the build machine repository. If I could retrieve the metadata files from the central repository, then it would be possible to upload a working remote repository to my build machine.

  • Use desktop widget to run corporate web application

    - by jonny
    So the question is simple: is it possible to set windows desktop to corporate application page (anybody remembers that active desktop thing?) and use it instead of browser (sic!). My thoughts: Windows 7: I can create giant full-screen widget that will show my page. Still have no idea if I will be able to navigate inside it though. Windows Vista: ???. I know there is still a side bar gadget that hosts a browser. Windows XP: create static html page with iframe pointing to corporate app home page. Problem: clicking links on page still opens default browser.

  • SQL tables using VARCHAR with UTF8 (with respect to multi byte character length)

    - by Elius
    Like in Oracle VARCHAR( 60 CHAR ) I would like to specify a varchar field with variable length depending on the inserted characters. for example: create table X (text varchar(3)) insert into X (text) VALUES ('äöü') Should be possible (with UTF8 as the default charset of the database). On DB2 I got this Error: DB2 SQL Error: SQLCODE=-302, SQLSTATE=22001 (Character data, right truncation occurred; for example, an update or insert value is a string that is too long for the column, or a datetime value cannot be assigned to a host variable, because it is too small.) I'm looking for solutions for DB2, MsSql, MySql, Hypersonic.

  • Struts. Go back to same page after an action

    - by framara
    Hi there, my situation is the following: I have a project with JSP, Struts and a lot of actions. Lets say that I have these 3 main groups {contacts.do, calendar.do and notes.do} with lot of actions in each of them. I have an action unrelated to all of them but since I didn't know where to put it I just chose contacts. My aim is after the action, to go back to the page I was but since the action is place in contacts it returns to the default action of contacts. Is there anything I could do for this purpose? Thank you.

  • are Hierarchical SIngletons in Java possible?

    - by Zach H
    I've been toying with an interesting idea (No idea if I'll include it in any code, but it's fun to think about) Let's say we have a program that requires a large number of classes, all of a certain subclass. And those classes all need to be singletons. Now, we could write the singleton pattern for each of those classes, but it seems wasteful to write the same code over and over, and we already have a common base class. It would be really nice to create a getSingleton method of A that when called from a subclass, returns a singleton of the B class (cast to class A for simplicity) class A{ public A getSingleton(){ //Wizardry } } class B extends A{ } A blargh = B.getSingleton() A gish = B.getSingleton() if(A == B) System.out.println("It works!") It seems to me that the way to do this would be to recognize and call B's default constructor (assuming we don't need to pass anything in.) I know a little of the black magic of reflection in Java, but i'm not sure if this can be done. Anyone interested in puzzling over this?

  • Set plugin’s version on the command line in maven 2

    - by larry cai
    I generate default quickstart maven example, and type mvn checkstyle:checkstyle, it always try to use the lastest SNAPSHOT version, probably it is wrong in my nexus server, but How can I set plugin's version on the command line in maven2, like 2.5 for checkstyle instead of 2.6-SNAPSHOT C:\HelloWorld>mvn checkstyle:checkstyle [INFO] Scanning for projects... [INFO] Searching repository for plugin with prefix: 'checkstyle'. [INFO] ------------------------------------------------------------------------ [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] Error building POM (may not be this project's POM). Project ID: org.apache.maven.plugins:maven-checkstyle-plugin Reason: Error getting POM for 'org.apache.maven.plugins:maven-checkstyle-plugin' from the repository: Failed to resolve artifact, possibly due to a repository list that is not appropriately equipped for this artifact's metadata. org.apache.maven.plugins:maven-checkstyle-plugin:pom:2.6-SNAPSHOT from the specified remote repositories: nexus (http://localhost:9081/nexus/content/groups/public) for project org.apache.maven.plugins:maven-checkstyle-plugin I guess it could be "mvn checkstyle:2.5:checkstyle", unfortunately it is not. Surely if I set build dependance in pom.xml, it will work, but I want to see how command line can works

  • Compiler error while compiling the RAPID library on VS2008

    - by Demi
    I've downloaded the RAPID library and tried to compile it on Microsoft Visual Studio 2008. However, I'm getting the following compiler error: C4430 missing type specifier - int assumed. Note: C++ does not support default-int at this code segment (the exact line that produces the error is int flag): class RAPID_model { public: box *b; int num_boxes_alloced; tri *tris; int num_tris; int num_tris_alloced; int build_state; int build_hierarchy(); friend RAPID_Collide(double R1[3][3], double T1[3], double s1, RAPID_model *RAPID_model1, double R2[3][3], double T2[3], double s2, RAPID_model *RAPID_model2, int flag); Can anyone please help me with this? Thank you

  • Loop on enumeration values

    - by Rachel
    How awful is it - or is it perfectly acceptable - to index a loop on an enumeration? I have an enumeration defined. The values of the literals are default values. The assigned values do not have any significance, will not have any significance, and the values of any literals added in the future will also not have any significance. It's just defined to limit the allowed values and to make things easier to follow. Therefore the values will always start at 0 and increase by 1. Can I set up a loop like so: enum MyEnum { value1, value2, value3, maxValue } for(MyEnum i = value1; i < maxValue; i = static_cast<MyEnum>(i+1)){}

  • Is the XML processing instructions node mandatory ?

    - by ereOn
    I had a discussion with a colleague of mine about the XML processing instructions node (I'm talking about this = <?xml version="1.0" encoding="UTF-8"?>). I believe that for something to be called "valid XML", it requires a processing instructions node. My colleague states that the processing instruction node is optionnal, since the default encoding is UTF-8 and the version is always 1.0. This make sense, but what does the standard says ? In short, given the following file: <books> <book id="1"><title>Title</title></book> </book> Can we say that: It is valid XML ? It is a valid XML node ? It is a valid XML document ? Thank you very much.

  • Updating .net 4.0 machine.config seems to have no effect

    - by Jon P
    I'm feeling stupid. I've just created my first ASP.net 4.0 site after working my way though over the years from 1.1 upwards. We have several settings at the machine.config level that I need to migrate to the new 4.0 machine.config. I though I had be adding the required connection strings to the connection string section of the following two files: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\machine.config C:\Windows\Microsoft.NET\Framework\v4.0.30319\machine.config When I created a new website in IIS and assigned it to the ASP.net 4.0 Application pool I only get the default LocalSqlServer connection string. I tried editing the name of this in the two files above to indicate which file it was in, but there was no change. Are there machine.config files in other locations I should be looking at?

  • Form submission and hyperlinks using GET and POST

    - by Jon
    I have a search resource, the user can perform searches by filling out a form and submitting it, the create action is called, the Search is saved, the show action is called, and the results are displayed. This all happens with the default POST, and all works fine. The user may want to save his search in the saved_search table (i don't use the Search table for this purpose as this table stores all searches for the purpose of compiling statistics, and gets cleared on a regular basis). Once the Search is saved, it can be re-run by clicking a hyperlink, this is where i start to get problems. I see no way of getting my hyperlink to run the create action of Search, with a POST request, and the necessary data. I then decided to try to get both form submission and the hyperlink to perform a search using a GET request, i was unable to get form_for to run my Search create action using a GET request, it always seems to get routed to my index action. Can someone suggest a good restful solution to this problem please. Many thanks

  • Signed and unsigned, and how bit extension works in C

    - by hatorade
    unsigned short s; s = 0xffff; int i = s; How does the extension work here? 2 larger order bytes are added, but I'm confused whether 1's or 0's are extended there. This is probably platform dependent so let's focus on what Unix does. Would the two bigger order bytes of the int be filled with 1's or 0's, and why? Basically, does the computer know that s is unsigned, and correctly assign 0's to the higher order bits of the int? So i is now 0x0000ffff? Or since ints are default signed in unix does it take the signed bit from s (a 1) and copy that to the higher order bytes?

  • C Newbie, ascii control function

    - by user570607
    Hey there, I have written a program that works well in C that converts non-readable ASCII to their character values. I would appreciate if a C master? would show me a better way of doing it that I have currently done, mainly this section: if (isascii(ch)) { switch (ch) { case 0: printControl("NUL"); break; case 1: printControl("SOH"); break; .. etc (32 in total) case default: putchar(ch); break; } } Is it normal to make a switch that big? Or should I be using some other method (input from an ascii table?)

  • Is there a need for zero-out DIV's margin and padding?

    - by ssg
    I wonder if on any browser div element comes with a preset margin/padding value other than zero. As far as I know, div and span come with zero padding and margin values by standard to make them suitable canvas for style decoration. Even better, is there a definite standard for default styles for all elements that is cross-browser which we can make assumptions upon? For instance FORM comes with top/bottom margins, OL/UL come with padding-left's. I occasionally see a * { margin: 0; padding: 0; } and this just looks like a dirty hack without knowing the reasons or consequences. Anyone has any better approach to this?

  • Need help with cURL and POSTing in PHP

    - by alex
    I need to post to a payment gateway. The example PHP script for the gateway simply sets the XML like this curl_setopt($ch, CURLOPT_POSTFIELDS, $xmlRequest); // $xmlRequest is just a string of XML In all of my experience, generally you need to use an array with key/values or a string similar to GET params. I am using Kohana, and tracked down a cURL module. It accepts the POST key/values as an array only. Now, I could ditch the module and throw some cURL straight in, but I am using this module fine all throughout the site, so would prefer to use it here. So, my question is, how does that first one work? Does it just POST the whole thing without any named key? Is there a default key I could use for an array to get the module to work?

    My search server 2008 express crawls 3 sharepoint servers and 1 windows file server. The file server and 2 other sharepoint server crawl all content and master and sub sites just fine. On the 3rd sharepoint server the default site crawl just fine...The second web application site (content database) crawls the top site and crawls all sub sites BUT The subsites get the below error in the crawl log. Deleted by the gatherer (The start address or content source that contained this item was deleted and hence this item was deleted.) I have checked the security rights (OK) I have checked the setting to crawl a SharePoint site (if wrong the top site would not work)... ???? Last part = I can crawl 3 other sharepoint sites (web applications/other content databases) on the same server...It seems to be just this one site...

  • How do I clear MVC client side validation errors when a cancel button is clicked when a user has inv

    - by Sci-fi
    I have a partial view that is rendered within a main view. The partial view takes advantage of System.ComponentModel.DataAnnotations and Html.EnableClientValidation(). A link is clicked, and div containing the partial view is displayed within a JQuery.Dialog(). I then click the save button without entering any text in my validated input field. This causes the client side validation to fire as expected, and display the '*required' message beside the invalid field. When the cancel button is clicked, I want to reset the client side MVC validation back to it's default state and remove any messages, ready for when the user opens the dialog again. Is there a recommended way of doing this?

  • C# Possible to partial class "program" class for a console application?

    - by JL
    I was wondering if its possible to change the default "program" class that gets created for any console application to a partial class. I want to do this because I want better organisation rather than have all methods in 1 file categorized by region. It would make more sense for me to have certain method categories sitting in separate files. My understanding of a partial class is that it is a class definition in multiple files that during a compile merges the class files into 1 class unit. I could be wrong, or there could be a better way for me to achieve better organisational structure. Any suggestions would help, and thanks

  • How do I cancel a text selection after the initial mousedown event?

    - by cwillu-gmail
    I'm trying to implement a pop-up menu based on a click-and-hold, positioned so that a (really) slow click will still trigger the default action, and with the delay set so that a text-selection gesture won't usually trigger the menu. What I can't seem to do is cancel the text-selection in a way that doesn't prevent text-selection in the first place: returning false from the event handler (or calling $(this).preventDefault()) prevents the user from selecting at all, and the obvious $().trigger('mouseup') doesn't doesn't do anything with the selection at all. This is in the general context of a page, not particular to a textarea or other text field. e.stopPropogation() doesn't cancel text-selection. I'm not looking to prevent text selections, but rather to veto them after some short period of time, if certain conditions are met.
