  • Java - Syntax Question: What is <? super T>

    - by aloh
    I'm having trouble understanding the following syntax: public class SortedList< T extends Comparable< ? super T> > extends LinkedList< T > I see that class SortedList extends LinkedList. I just don't know what T extends Comparable< ? super T> means. My understanding of it so far is that type T must be a type that implements Comparable...but what is "< ? super T "?

  • First iPhone App View Position Problem

    - by hytparadisee
    I am closely following the instructions given in the tutorial "Your First iPhone Application" on apple ADC. In the interface builder, I have set up a button positioned on the top according to the Apple Interface Guidelines. It runs without trouble if I simulate the interface in IB. However, if I run the built app, I get what is shown here. If you look at the view clearly, you will see that the entire view has been shifted up. And the magnitude of the shift is exactly the height of the status bar. And that's why the there is blank space at the bottom of the window, which was white instead of red. I have tried turning on the "Simulated Interface Elements", but that doesn't work either. The problem persists on real devices as well. However, using the "Simulate Interface" from IB looks fine. Any help is appreciated. Yun Tao

  • Help with running crontab from root

    - by user242065
    Im using OSX and having trouble getting a cron job to run.

  • Best tool for monitoring Coldfusion interoperability with .Net web service

    - by John Galt
    Is there a tool to see the message sent to webservice hosted on an IIS server? I have a webservice written in .Net and our ColdFusion people are having trouble building a "complex" parameter. This problem is described from a ColdFusion perspective at: adobe forum question It runs when called from a .net client. While hosted on a server inside our LAN, I put it out on a public server so the WSDL could be viewed: please take a quick look at this WSDL here When the CF developer runs her code, she gets: java.lang.IllegalArgumentException: argument type mismatch ...and I am wondering if there is a tool I could run on the server that hosts my webservice to see if it is even entering the WS or is being rejected by Java code that CF uses and is not really even getting to my webservice.

  • Browser not handling exception from AJAX panel, ASP.NET c#

    - by Grant
    Hi, i am having trouble catching errors in an AJAX panel. Even when i throw an exception in the c# code behind the front end completely ignores it. Here is the code i have setup, can anyone see why? I ideally want to show a js alert window on error. Code Behind: protected void btnX_Click(object sender, EventArgs e) { throw new ApplicationException("test"); } protected void ScriptManager_AsyncPostBackError(object sender, AsyncPostBackErrorEventArgs e) { ScriptManager.AsyncPostBackErrorMessage = e.Exception.Message; } Markup: <script type="text/javascript" language="javascript"> Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler); function EndRequestHandler(sender, e) { window.alert(e.get_error().name); } </script> <asp:ScriptManager ID="ScriptManager" runat="server" AllowCustomErrorsRedirect="true" OnAsyncPostBackError="ScriptManager_AsyncPostBackError" />

  • Lua - How to use functions from another script

    - by Person
    I'm wondering how to use functions from another script in Lua. For example, say GameObjectUtilities holds functions that many GameObject scripts will use. The Slime (a GameObject) script wants to use a function in GameObjectUtilities. I'm having trouble getting this to work. I've looked here, but I still don't really fully understand. Do I need to create a module or a table to hold the functions in GameObjectUtilities for the functions in it to be used in other scripts? If so, what is the best way to go about this?

  • Setting a form field's value during validation

    - by LaundroMat
    I read about this issue already, but I'm having trouble understanding why I can't change the value of a form's field during validation. I have a form where a user can enter a decimal value. This value has to be higher than the initial value of the item the user is changing. During clean(), the value that was entered is checked against the item's previous value. I would like to be able to re-set the form field's value to the item's initial value when a user enters a lower value. Is this possible from within the clean() method, or am I forced to do this in the view? Somehow, it doesn't feel right to do this in the view... (To make matters more complicated, the form's fields are built up dynamically, meaning I have to override the form's clean() method instead of using the clean_() method).

  • How do I scope variables properly in jQuery?

    - by safetycopy
    I'm working on a jQuery plugin, but am having some trouble getting my variables properly scoped. Here's an example from my code: (function($) { $.fn.ksana = function(userOptions) { var o = $.extend({}, $.fn.ksana.defaultOptions, userOptions); return this.each(function() { alert(rotate()); // o is not defined }); }; function rotate() { return Math.round(o.negRot + (Math.random() * (o.posRot - o.negRot))); }; $.fn.ksana.defaultOptions = { negRot: -20, posRot: 20 }; })(jQuery); I'm trying to get the private function rotate to be able to see the o variable, but it just keeps alerting 'o is not defined'. I'm not sure what I'm doing wrong.

  • Number distribution

    - by Carra
    Problem: We have x checkboxes and we want to check y of them evenly. Example 1: select 50 checkboxes of 100 total. [-] [x] [-] [x] ... Example 2: select 33 checkboxes of 100 total. [-] [-] [x] [-] [-] [x] ... Example 3: select 66 checkboxes of 100 total: [-] [x] [x] [-] [x] [x] ... But we're having trouble to come up with a formula to check them in code, especially once you go 11/111 or something similar. Anyone has an idea?

  • How can I get Weblogic to connect to a RedBrick database?

    - by Scott
    I am trying to get Weblogic 9.2.3 to talk to a legacy RedBrick database and am having trouble. I have the redbrick.jar file from the software installation and have added to my APP_RUNTIME_CLASSPATH and my MANIFEST_CLASSPATH. This is my jConnect template line: <url>jdbc:rbw:protocol:${DB_LT_SERVER}:${DB_LT_PORT}/${DB_LT_NAME}</url> <driver-name>redbrick.jdbc.RBWDriver</driver-name> (Variables get replaced with good values during build.) When starting up I get this error: weblogic.common.ResourceException: Unknown Data Source jConnectLT weblogic.common.resourcepool.ResourceSystemException: Cannot load driver class: redbrick.jdbc.RBWDriver Do I have to do more to make Weblogic see the RedBrick database? Thanks for any tips or pointers.

  • How to replicate this screenshot in WebForms?

    - by AngryHacker
    I need to replicate the following in ASP.NET WebForms using a GridView. But I am not sure where to start. Basically I need 3 columns. The checkbox (which sometimes needs to be disabled), and 2 standard text columns. I've gone through the tutorial and I can see how to basically dump text data into a GridView, but not clear on how to implement checkboxes, particularly ones that needs to be disabled once in a while. And I have to replicate the style of the screenshot (e.g. border on the bottom). Having trouble with that as well. How do I swing something like that?

  • How to get REALLY fast python over a simple loop

    - by totallymike
    I'm working on a spoj problem, INTEST. The goal is to specify the number of test cases (n) and a divisor (k), then feed your program n numbers. The program will accept each number on a newline of stdin and after receiving the nth number, will tell you how many were divisible by k. The only challenge in this problem is getting your code to be FAST because it k can be anything up to 10^7 and the test cases can be as high as 10^9. I'm trying to write it in python and having trouble speeding it up. Any ideas? import sys first_in = raw_input() thing = first_in.split() n = int(thing[0]) k = int(thing[1]) total = 0 i = 0 for line in sys.stdin: t = int(line) if t % k == 0: total += 1 print total

  • how to convert numbers to alpha numeric system with php

    - by Patrick
    Im not sure what this is called, which is why im having trouble searching for it. What im looking to do, is take numbers, and convert them to some alpha numeric base so that the number say 5000, wouldnt read 5000, but like G4u or something like that. The idea being to save space and also not make it obvious how many records there are in a given system. Im using php, so if there is something like this built into php even better, but even a name for this method would be helpful at this point Again, sorry for not being able to be more clear, im just not sure what this is called.

  • Where does the data model go in a Prism app?

    - by HawkeyeJoeS
    I'm having trouble where to put our data model in our Prism app. Most, if not all or our data will be coming from web services and the web services are unique for each module. Unfortunately, there will be objects that need to be shared (such as a person/user object). I'm really torn about whether to add these services directly to the module, so that each is truly independent, or create a separate project to house the web service proxies and business entities. The modules are being built by different teams, but will all live in the same solution (and source control, of course).

  • StreamTokenizer Iterator Adapter help

    - by alpdog14
    I have this StreamTokenizer Iterator Adapter that is suppose to create a Tokenizer Iterator Index Builder then build the index from a STIA wrapped around a StreamTokenizer.

  • Understanding c++ block of code

    - by kotoko
    I was given a c++ main and have to code it so it works. I am having some trouble understanding the code as I am a bit new to cpp. Here is the code int main(int argc, char *argv[]) { Class::setAtribute("string"); Class(Class::CONSTANT) << "starting up..."; } Some questions: How can the first line work with no variables? Is it static? The second line is really strange for me, what I can make out is a Constructor that takes in a class constante and then prints it out somehow? If someone could explain me this bit of code it would be great! Thanks in advance.

  • Property Scope (Iphone)

    - by Hank
    Hello All. I am having trouble accessing a declared property and I think I am missing something fundamental about the nature of properties and perhaps view controllers. Here's what I'm doing so far: declaring a property "myPhone" in a root view controller called RootViewController. grabbing a phone number from a modally presented people picker setting "myPhone" to the value from the people picker (from within shouldContinueAfterSelectingPerson of ABPeoplePickerNavigationController) trying to access "myPhone" from another modally presented view controller "myPhone" continues to NSLog to null despite trying every permutation of self.myPhone, super, RootViewController, etc. to try and access the value I set. What am I missing?

  • Why does the infobox in my MSN Map not close?

    - by meder
    I'm having a bit of trouble with this map, invoked by the "View our interactive map" button in the middle of the content area. If you double click a point such as 8 which causes a zoom and then afterwards it causes the info box to appear, the hide logic is wrong. If you try to close the x, it will fail. This is probably because the user clicked too fast and the map thinks its in zoom mode when infact it should be in info box mode. Has anyone ran into this issue before? Looks like I have to mess around with window.ero.hide and some other functions.. because map.HideInfoBox doesn't hide the map. EDIT: The script used is here. I did not code it, but the relevant bit has: onclick="EnableEroHide();map.HideInfoBox();changePin();return false;" The map.HideInfoBox() should hide the info box.

  • cross domain gwt ?

    - by jlo
    is there a way to run gwt on a proxy loaded web page ? ex) using proxy script on myexamplesite.com that loads finance.google.com, and running GWT on the newly loaded page. I've been doing the above before I found about GWT, using LAMP stack + Jquery (UI), which quickly turned out to be crap and inefficient. All this trouble to bypass browser's default Single Origin Policy. So, right now, is it possible to overcome this problem with GWT ? Is it possible to some how, run javascript on a html page from finance.google.com loaded into myexamplesite.com's frame with GWT or other solution? I am not looking to do JSON or RSS related topics. What I need is high lighted in bold. Is GWT + Gears what I should be using ? Thank you.

  • SharePoint - Auto-increment dates in new records?

    - by ACal
    Hello, I have a list that's going to be updated with relatively static data weekly, and I wanted to create a workflow to do this automatically. The only field I'm having trouble with is Start Date. I want the new Start Date to be exactly one week after the previous week's (row's) Start Date, but I can't figure out how to capture this. I can't seem to find an easy way to get the value of the previous row. Now, theoretically, I could just have the workflow run once a week on a given day and use [Today] as the value for the field; however, a requirement is that the list can be populated a few weeks in advance if needed. Thanks in advance for any help you can provide!

  • WCF client hangs on response

    - by JohnIdol
    I have a WCF client (running on Win7) pointing to a WebSphere service. All is good from a test harness (a little test fixture outside my web app) but when my calls to the service originate from my web project one of the calls is extremely slow to deserialize (it takes up to 10 times longer) and not just the first time. I can see from fiddler that the response comes back quickly but then the WCF client hangs on the response itself for more than a minute before the next line of code is hit by the debugger, almost if the client was having trouble deserializing. This happens only if in the response I have a given pdf string, base64 encoded chunked. If for example the service raises a fault (this pdf string is not there) then the response is deserialized immediately. Again, If I send the exact same envelope through Soap-UI or from outside the web project all is good. I am at loss - What should I be looking for and is there some config setting that might do the trick? Any help appreciated!

  • Correct folder structure for sites

    - by Francesca
    I've just started tidying up the server for a particular site and am running into some trouble when moving files. I originally had style.css in my main folder, and another folder called images, so paths in the .css went images/myimage.png Now I have moved style.css into another folder called css. So the image links in the CSS no longer work, as it's looking for the folder images from it's own CSS folder. I changed the file path to /images/myimage.png as I thought this would make it climb up a level and then look for the images folder, but this doesn't seem to work. I'm interested to see what solutions people have and also any suggestions on how people organise their folders for a particular site. Thanks!
