  • Simple javascript problem in ie6 and ie7

    - by Jeff Lamb
    I have a very simple function that takes a list of comma separated (x,y) points and imports them into a graph. I have FF, Chrome and IE8 installed. I use IETester to test for IE6 and IE7. // Import Data this.Import = function(data) { alert("Data in: "+data); var d; // Make sure the first and the last are start/ending parenthesis if ( (data[0] != '(') || (data[data.length-1] != ')') ) { alert("After if: "+data[0]+" "+data[data.length-1]); return false; } ... In Chrome, FF and IE8, I don't see the "After if:" alert. In IE6 and IE7, I see the following two alerts: Data in: (52,16),(100,90) After if: undefined undefined The "Data in" alert matches in all browsers. Any ideas?

  • IIS 6.0: what is the WMI equivalent of "Convert Folder To Application"?

    - by Richard Berg
    Basically, imagine you need to automate these steps: Open Internet Information Services. Find the web site, find the folder, right click the folder and select properties. Click the Directory folder. Under Applications settings, click the Create button. The application is now created. Click OK to finish. (click for a pictoral walkthru) My end goal is Powershell, but answers that use JScript or VB.NET or whatever are fine too. Bonus points if the same code works against an IIS7 application running in 6.0 Compatibility Mode.

  • Actionscrips/Flex4: Display cut-off datapoints differently in LineChart

    - by Limited Atonement
    Dear Sirs, The issue arises when the user selects a range on the linechart that cuts off datapoints. When this happens, I would like the chart to tell the user somehow that there are data points three, just outside the range, perhaps by drawing a straight line across the top or bottom of the graph. How can I get Flex to do this for met? Let me know if you understand the question, or if you need more information, and of course, let me know the answer! Thanks! Sincerely, Aaron

  • How do I draw part of parabola using iText ? Or how do I create quadratic bezier curves from cubic b

    - by drasto
    I need to draw a shape whose boundaries are parts of parabola (that is quadratic bezier curves) using iText. I have found only method for drawing cubic bezier curves in PdfContentByte class. So how do I draw quadratic bezier curves using iText ? One way would be to use method for cubic bezier curves. Is it possible to draw quadratic bezier curves as a cubic bezier curves (with 2 control points). I gues it is but I cannot make up the formula. If somebody states the formula tu "translate" cubic bezier curves to quadratic that would solve the problem. Any other ways to draw quadratic bezier(parts of parabola) curves in iText (and filled shapes made of them) is also the solution. Thanks

  • Hidden features of CSS

    - by alex
    I have definitely picked up some useful tips in the hidden features style questions concerning PHP and XHTML. So here is one to cover CSS. While easy to pick up, it takes a little while to learn about everything, their default behaviors, properties etc Here are some to start the ball @charset "UTF-8"; /* set the character set. must be first line as Gumbo points out in comments */ .element { /* takes precedence over other stylings */ display: block !important; /* mozilla .... rounded corners with no images */ -moz-border-radius: 10px; /* webkit equivalent */ -webkit-border-radius: 10px } These are not so much hidden, but their use is not often widespread. What tips, tricks, rare features have you discovered with CSS?

  • How to use DoG Pyramid in SIFT

    - by Ahmet Keskin
    Hi all, I am very new in image processing and pattern recognition. I am trying to implement SIFT algorithm where I am able to create the DoG pyramid and identify the local maximum or minimum in each octave. What I don't understand is that how to use these local max/min in each octave. How do I combine these points? My question may sound very trivial. I have read Lowe's paper, but could not really understand what he did after he built the DoG pyramid. Any help is appreciated. Thank you

  • Allowing optional variables with Rewrite Cond

    - by James Doc
    I currently have the following code: RewriteCond %{REQUEST_URI} !assets/ RewriteCond %{REQUEST_URI} !uploads/ RewriteRule ^([a-z|0-9_&;=-]+)/([a-z|0-9_&;=-]+) index.php?method=$1&value=$2 [NC,L] This works perfectly to redirect 'page/home' to 'index.php?method=page&value=home. However at some points I need to add an extra variable or two to the query string such as 'admin/useraccounts/mod/2'. When I simply tack on bits to the end of the rewrite rule it works if all the variables are 'page/home/rand/rand' or 'admin/useraccounts/mod/2', but if anything is missing such as 'page/home' I get a 404. What am I doing wrong? Many thanks.

  • Django file uploads - Just can't work it out

    - by phoebebright
    OK I give up - after 5 solid hours trying to get a django form to upload a file, I've checked out all the links in stackoverflow and googled and googled. Why is it so hard, I just want it to work like the admin file upload? So I get that I need code like: if submitForm.is_valid(): handle_uploaded_file(request.FILES['attachment']) obj = submitForm.save() and I can see my file in request.FILES['attachment'] (yes I have enctype set) but what am I supposed to do in handle_uploaded_file? The examples all have a fixed file name but obviously I want to upload the file to the directory I defined in the model, but I can't see where I can find that. def handle_uploaded_file(f): destination = open('fyi.xml', 'wb+') for chunk in f.chunks(): destination.write(chunk) destination.close() Bet I'm going to feel really stupid when someone points out the obvious!

  • How do I include full PartCover results with TeamCity 5?

    - by Jim Geurts
    Hi, I'm trying to get PartCover reports to generate correctly in TeamCity 5.0. When I click the Code Coverage tab in the build details, the reports are empty. I'm using the sln2008 build agent and my PartCoverage settings are as follows: Include Patterns: [*]* Report XSLT: C:\Program Files\PartCover .NET 2.3\xslt\Report By Assembly.xslt=>ByAssembly.html C:\Program Files\PartCover .NET 2.3\xslt\Report By Class.xslt=>ByClass.html Bonus points if you can describe how to include those reports (or just the important parts) with the email that TeamCity sends for successful/failed builds. I would like to continue using the sln2008 build agent, if possible, and not a different build agent.

  • How to get IzPack tocheck for an existing version of the software?

    - by bguiz
    Hi, I have an application for which we use IzPack to create the installer. The installer is working fine in its current state, however, I need to add functionality that enables it to check whether an existing version of the software has been installed. I understand IzPack supports this out of the box using its CheckedHelloPanel, unfortunately that only works for Windows, as it appears to depend on the windows registry. Is there a way to configure IzPack such that it is able to detect existing installations? I need to be able to detect whether there is one and merely display a message notifying the user... Bonus points for how to give the user the option to trigger the uninstaller of the existing installation. Assume that the software will only be installed using the new installer IzPack only: please do not suggest alternatives, as we cannot change that now If you suggest using <validator>, please include a code sample of the validator class, because I have considered this, but don't know where to start

  • Obfuscating Geocode results to protect privacy?

    - by Kevin
    I have an app that finds other users within a 20 mile radius on a google map and associates an icon with each of them. However, I do not want their exact points to be given but rather an approximation. I've wrestled with a few ideas on how to do this: Only Geocode the Zip Code, make graphic icons for 1-99, use the icon to represent how many results are within the zip code, and use the info window to show hyperlinks to the individual results. The only problem is, I'd like each individual icon to be shown because it just looks a lot better. Add/Subtract a random number to the lat/lng values stored with each user and add a translucent circle around the icon. What do you guys suggest?

  • How to design this class hierarchy?

    - by devoured elysium
    I have defined an Event class: Event and all the following classes inherit from Event: AEvent BEvent CEvent DEvent Now, with the info I gather from all these Event classes, I will make a chart. With AEvent and BEvent, I will generate points for that chart, while with CEvent and DEvent I will paint certain regions of the chart. Now, how should I signal this in my class hierarchy? Should I make AEvent and BEvent inherit from PointEvent while CEvent and DEvent inherit from RegionEvent, being that both RegionEvent and PointEvent inherit from Event? Should I add a field with an Enum to Event with 2 values, Point and Region, and each of the child classes set their value to it? Should I use some kind of pattern here? Which one? Thanks.

  • Pointer initialization doubt

    - by Jestin Joy
    We could initialize a character pointer like this in C. char *c="test"; Where c points to the first character(t). But when I gave code like below. It gives segmentation fault. #include<stdio.h> #include<stdlib.h> main() { int *i=0; printf("%d",*i); } Also when I give #include<stdio.h> #include<stdlib.h> main() { int *i; i=(int *)malloc(2); printf("%d",*i); } It worked(gave output 0). When I gave malloc(0), it worked(gave output 0). Please tell what is happening

  • Iphone SDK array initlised at viewdidload and released at dealloc is causing leak?

    - by Skeep
    Hi All, I am new to iphone development and i am getting ready to submit my first app. I have an array initlised at viewdidload and released at dealloc, however it is causing a leak. My question is why would this happen is it because the dealloc has not run? My Code is as follows the NSMutableArray called listOfItems is referenced in my .h file for the UITableView. The listOfItems array is used to populate the table. In the viewDidLoad method i have this code listOfItems = [[NSMutableArray alloc] init]; and in the dealloc i have: [listOfItems release]; When watching leaks in instruments I get a NSArray leak which when I drill down points to the line: listOfItems = [[NSMutableArray alloc] init]; Am i putting all this in the right place? Thanks

  • How to get all visible markers on current zoom level

    - by nefo_x
    Here are some points: 1) I have some markers on the map and records associated with it on the right panel besides the map. They are connected via numeric id, which is stored as a property of marker. 2) All the markers are stored in an array. 3) When the user zooms in the map, records, associated to only visible markers should be shown on the right panel. So, how to get the list of all visible markers on the current zoom level? I've searched over the internet and didn't find something useful. Some kind of what I'm trying to achieve could be found here

    - by melis
    i have two cartesian coordinates. There are xyz and BIG XYZ. I want to make these are paralel each other.forexample , x paralel to X ,y paralel to Y and z paralel to Z. I use rotation matris but I have a lot of different rotation matris . for example I have 3D point in xyz cartesien coordinates and its called A. and I want to change cartesien coordinate to BIG XYZ and find the same 3D point in this coordinates its called B.Until now it is okay. But when I used different rotational matris , points were changed.what can I do? Which Euler rotations can i use?

  • comparing two angles

    - by Elazar Leibovich
    Given four points in the plane, A,B,X,Y, I wish to determine which of the following two angles is smaller ?ABX or ?ABY. I'd rather not use cos or sqrt, in order to preserve accuracy. In the case where A=(-1,0),B=(0,0), I can compare the two angles ?ABX and ?ABY, by calculating the dot product of the vectors X,Y, and watch it's sign. What I can do in this case is: Determine whether or not ABX turns right or left If ABX turns left check whether or not Y and A are on the same side of the line on segment BX. If they are - ?ABX is a smaller than ABY. If ABX turns right, then Y and A on the same side of BX means that ?ABX is larger than ?ABY. But this seems too complicated to me. Any simpler approach?

  • Good .NET based CMS?

    - by rAm
    For many projects we had to choose a CMS platform. I came across a few CMS platforms based on .NET. I want to know your experience. Community Server (cannot be called a true CMS) DotNetNuke (DNN) Umbraco Kentico Sitefinity Can you please touch upon the following points: UI customization. Feature extension. Third party extensions Support And most important: how much time it takes to learn, as a programmer and someone who manages the application with little or no programming knowledge. Update: thanks for all the responses, I have seen the other thread but did not get a satisfactory reply addressing the Support and Time? (which I forgot to add earlier).

  • How do languages handle side effects of compound operators?

    - by Kos
    Hello, Assume such situation: int a = (--t)*(t-2); int b = (t/=a)+t; In C and C++ this is undefined behaviour, as described here: Undefined Behavior and Sequence Points However, how does this situation look in: JavaScript, Java, PHP... C# well, any other language which has compound operators? I'm bugfixing a Javascript - C++ port right now in which this got unnoticed in many places. I'd like to know how other languages generally handle this... Leaving the order undefined is somehow specific to C and C++, isn't it?

  • wcf class implementing two operation contracts in different service contracts with same name

    - by Archie
    Hello, I have declared two service contracts as follows: [ServiceContract] public interface IContract1 { [OperationContract] double Add(int ip); } [ServiceContract] public interface IContract2 { [OperationContract] double Add(double ip); } I have a class which implements these two contracts. I have created two end points for both the contracts. But I'm not able to access the service from client code. It displays a big error when i try to update the service reference as: Metadata contains an error that cannot be resolved.... There was no endpoint listening at ... etc. I know that you can't have two OperationContracts with the same name but is it possible to have two operation contracts in different service contracts with same name but different signature? Thanks.

  • Plot smooth line with PyPlot

    - by Paul
    I've got the following simple script that plots a graph: import matplotlib.pyplot as plt import numpy as np T = np.array([6, 7, 8, 9, 10, 11, 12]) power = np.array([1.53E+03, 5.92E+02, 2.04E+02, 7.24E+01, 2.72E+01, 1.10E+01, 4.70E+00]) plt.plot(T,power) plt.show() As it is now, the line goes straight from point to point which looks ok, but could be better in my opinion. What I want is to smooth the line between the points. In Gnuplot I would have plotted with smooth cplines. Is there an easy way to do this in PyPlot? I've found some tutorials, but they all seem rather complex.
