• How to prevent a specific directory from running Php, Html, and Javascript languages?

  - by Emily

  Hi, Let's say i have an image uploader script, i want to prevent the upload directory from executing Php or even html by only showing it as plain text, i've seen this trick in many websites but i don't know how they do it. Briefly, if i upload evil.php to that directory, and i try to access it i will only see a plain text source , No html or php is executed. ( but i still want the images to appear normally ofcourse) I know i can do like that by header("content-type:text/plain"); but that's will not be helpful, because what i want, is to set the content-type:text/plain automatically by the server for every thing outputed from the upload directory except images. Note: i'm running php 5.3.2/Cent OS and the latest cPanel. Thanks

• Large static arrays are slowing down class load, need a better/faster lookup method

  - by Visualize

  I have a class with a couple static arrays: an int[] with 17,720 elements a string[] with 17,720 elements I noticed when I first access this class it takes almost 2 seconds to initialize, which causes a pause in the GUI that's accessing it. Specifically, it's a lookup for Unicode character names. The first array is an index into the second array. static readonly int[] NAME_INDEX = { 0x0000, 0x0001, 0x0005, 0x002C, 0x003B, ... static readonly string[] NAMES = { "Exclamation Mark", "Digit Three", "Semicolon", "Question Mark", ... The following code is how the arrays are used (given a character code). [Note: This code isn't a performance problem] int nameIndex = Array.BinarySearch<int>(NAME_INDEX, code); if (nameIndex > 0) { return NAMES[nameIndex]; } I guess I'm looking at other options on how to structure the data so that 1) The class is quickly loaded, and 2) I can quickly get the "name" for a given character code. Should I not be storing all these thousands of elements in static arrays?

• Huge framerate difference between Test and Publish movie in Flash?

  - by Glacius

  Simply put, I am making a flash midi player. I am using ENTER_FRAME for my timings. I set the framerate to 100 to ensure that the timing of each note in milliseconds is accurate. When I test the movie with CTRL + ENTER it works fine. When I publish it and open it in a browser (tested both IE and Chrome), it suddenly plays back a lot slower. I don't think it's a performance issue, since the code is very simple. If this slowdown is consistent then I can perhaps work with it so that the playback speed will be correct. Do browsers make the framerate slower or do they implement a framerate cap of some sort? What is going on?

• Double data entry system using Infopath 2007 how to compare 2 infopath documents for differences ?

  - by bugBurger

  How to compare 2 infopath documents craeted using double data entry system for differences ? We have a small project contains few infopath forms. Client is using double data entry system to reduce the errors. We are maintaining entry number in infopath form to seperate each entry. Note: I know we can compare xml data files of 2 documents. (xml data file has field names like field1,field2 and so on..while on form that field1 represent some meaninngful text) But the question is we want to compare it Visually side by side. Any difference should highlight the field.

• How can I use Object Oriented Javascript to interact with HTML Objects

  - by Steve

  I am very new to object orientated javascript, with experience writing gui's in python and java. I am trying to create html tables that I can place in locations throughout a webpage. Each html table would have two css layouts that control if it is selected or not. I can write all of the interaction if I only have one table. It gets confusing when I have multiple tables. I am wondering how to place these tables throughout a blank webpage and then access the tables individually. I think I am having trouble understanding how inheritance and hierarchy works in javascript/html. NOTE: I am not asking how to make a table. I am trying to dynamically create multiple tables and place them throughout a webpage. Then access their css independently and change it (move them to different locations or change the way the look, independently of the other tables).

• Iterator in Java.

  - by theband

  What is Iterator and collections? Does these two have any relations? // the interface definition Interface Iterator { boolean hasNext(); Object next(); // note "one-way" traffic void remove(); } // an example public static void main (String[] args){ ArrayList cars = new ArrayList(); for (int i = 0; i < 12; i++) cars.add (new Car()); Iterator it = cats.iterator(); while (it.hasNext()) System.out.println ((Car)it.next()); } Does the Interface Iterator has these method names alone predefined or its user defined?. What does these four lines below actually tell? cars.add (new Car()); Iterator it = cats.iterator(); while (it.hasNext()) System.out.println ((Car)it.next()); Thanks i am going through a book in collections.

• Threading Problems in ActionScript 2.0?

  - by yar

  Is it possible to have concurrency problems (thread competition) in an onEnterFrame method in ActionScript 2.0? I have written this cheesy code as a guard: if (!busy) { // I suspect some threading problems: is that even possible in flash busy = true; movePanels(); busy = false; } but this is no assurance against thread competition. If so, how can I do a basic semaphore/lock? Note: I suspect threading problems in my app, but if they're impossible, I'll check my code differently.

• Missing Status Bar in Visual Studio?

  - by Marcel

  Note: This question and answer is a full copy from Kelly Brownsbergers Blog. I do post it as a convenience to others. From time to time, my status bar disappears. I used to believe this was due to a botched install or add-in. I recently upgraded to Team System Test Edition, and my status bar again disappeared. For the last few weeks I’ve been trying to figure out a time to do a full reinstall. To not take rep for this, I have marked it communitiy wiki.

• What are the things Java got right?

  - by hamletdarcy

  What are the things that Java (the language and platform) got categorically right? In other words, what things are more recent programming languages preserving and carrying forward? Some easy answer are: garbage collection, a VM, lack of pointers, classloaders, reflection(?) What about language based answers? Please don't list the things Java did wrong, just right. (note by Mark Harrison) This is an interesting and useful question, especially for those of us who don't use java regularly. I'm voting for reopening. Please don't close as argumentative, as it doesn't seem to be causing any arguments.

• Finding Windows printer driver name using API

  - by Scott Bussinger

  I can't seem to find an API call that returns the driver name for a Windows printer. Note that I'm not talking about the friendly name of the printer in the printer folder, I'm talking about the name of actual driver being used as shown on the "Advanced" tab when you look at the printer properties: I'm trying to detect when I'm printing to the "Generic / Text Only" driver regardless of what name the user chooses for the printer. It doesn't seem like this should be hard, but I can't find it in the DEVMODE structure or anyplace else I've thought to look for it. Thanks for the help!

• g++ doesn't think I'm passing a reference

  - by Ben Jones

  When I call a method that takes a reference, g++ complains that I'm not passing a reference. I thought that the caller didn't have to do anything different for PBR. Here's the offending code: //method definition void addVertexInfo(VertexInfo &vi){vertexInstances.push_back(vi);} //method call: sharedVertices[index]->addVertexInfo(VertexInfo(n1index, n2index)); And here's the error: GLUtils/GLMesh.cpp: In member function 'void GLMesh::addPoly(GLIndexedPoly&)': GLUtils/GLMesh.cpp:110: error: no matching function for call to 'SharedVertexInfo::addVertexInfo(VertexInfo)' GLUtils/GLMesh.h:93: note: candidates are: void SharedVertexInfo::addVertexInfo(VertexInfo&)

• .NET 3.5 SP1 Code from Network - "The system cannot find the file specified."

  - by DaMoose

  This issue has nothing to do with whether the assemblies have been signed or caspol has been run for the shared network folder. Apparently, the location of the files is the issue, but I cannot find what the real problem is. I have one executable that references 5 dll's. I can run the app from a local drive without any problem. When I run the app from a network share, I get an error stating that "Could not load file or assembly 'homer, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified." If all the files are in the same folder, what is the error really telling me? I should note also that the framework used is 3.5 SP1, which does not require changing code access policy. I had tried that anyhow, and I received the same error in both cases. Thanks, DaMoose

• XmlNode.InnerText

  - by Jonathan.Peppers

  We have XML like so: <Example> <Node>Some text here <ChildNode>Child 1</ChildNode> <ChildNode>Child 2</ChildNode> </Node> </Example> We are using XmlDocument to parse this. When we have the XmlNode of the Node element, XmlNode.InnerText returns us this: "Some text hereChild 1Child2" How can we get the inner text of the Node element without the child nodes' inner text? We don't really want to use any Regex or string splitting to accomplish this. Note: We also don't want to switch to using a different set of classes to parse this XML, it would be too much of a code change.

• DOM Level 3 CustomEvents not bubbling on WebKit

  - by Edu Felipe

  I'm observing CustomEvents not bubbling, even though I set bubbling to true. The code below: var evt = document.createEvent("CustomEvent") evt.initCustomEvent("mycustomevent", true, false) var someh1 = document.getElementById("someh1") someh1.addEventListener("mycustomevent", function(){ alert("OMG!"); }) document.getElementsByTagName("body")[0].dispatchEvent(evt) With the HTML below: <html> <head></head> <body> <h1 id="someh1">content!</h1> </body> </html> Never shows the alert, demonstrating that the event is not bubbling down. Am I doing something wrong? Please note that if I do a getElementById("someh1") and run the dispatchEvent on it, the alert is displayed. Thanks!

• Howto get iframe linking to internal document source using javascript/jQuery?

  - by Tom

  Hi there, I have an iframe with id "appframe", the source is page.html and it's on the same server. I want to get the source of the page using jQuery. alert($("#appframe").contents().find("html").html()); returns <head></head><body></body> even though the document does not contain those tags, it only contains "Default page", so that is exactly what it should return. Any idea how to get the right source script of the whole document using jQuery? Eg. if the document would be "test" then that is exactly what it should return. Please note: I did ask this before a few weeks ago. Unfortunately, I got no solving answer. Because of my lower reputation (~85), I can not request a bounty... This doesn't make much sense to me. Anyway, it forced me to repost this question.

• Can you pass parameters for OnAction in MS Project VBA?

  - by Anne Schuessler

  The way I can define a method to be executed with OnAction in VBA with Microsoft Project is as follows (and works correctly): .OnAction = "Macro ""DoSomething""" ... where DoSomething is the method to execute. I would like to pass a parameter to that method but can't find a way to pass it with this syntax. Does anybody have an idea how to do this? I'm getting the feeling that this is an impossible task, but maybe there's some VBA secret I'm not aware of. Please note that VBA in MS Project seems to have its quirks and is slightly different than VBA for Excel or Access. This seems to be the case for the OnAction property which needs the extra Macro keyword to work correctly. If I'm wrong here please enlighten me.

• Can C# make my class look like another class?

  - by Vaccano

  I have a class that look like this: public class BasePadWI { public WorkItem WorkItemReference { get; set; } .... Other stuff ...... } I then have a dictionary that is defined like this: public Dictionary<BasePadWI, Canvas> Pad { get; set; } I would then like to make a call like this: List<WorkItem> workItems = Pad.Keys.ToList(); (Note: WorkItem is a sealed class, so I cannot inherit.) Is there some trickery that I could do in the class to make it look like a WorkItem? I have done this in the mean time: List<WorkItem> workItems = Pad.Keys.ToList().ConvertAll(x=>x.WorkItem);

• Reading bytes from a text file that has the form of machine code in C?

  - by rashid

  I have a text file with machine code in this form: B2 0A 05 B2 1A 01 B3 08 00 17 B2 09 18 where an instruction has this format: OP Mode Operand Note: Operand could be 1 or 2 bytes. Where:(example) OP = B2 Mode = 0A Operand = 05 How can I read the bytes in a variable? As shown in the above example. When i read the file I get individual characters. I have an array of pointers where I read individual line, but still cannot solve the problem of reading a byte. Any ideas,suggestions. I hope I am not confusing anyone here. Thank you.

• PyPy: What is all the buzz about?

  - by sub

  Note: The title is provocating (to make you click on it and want to close-vote the question) and I don't want to look preoccupated. Since some time now I read and heard more and more about PyPy. It's like a linear graph. Why is PyPy so special? As far as I know implementations of dynamic languages written in the languages itself aren't such a rare thing, or am I not getting something? Some even people call PyPy "the future" [of python], or see some sort of deep potential in this implementation. What exactly is the meaning of this?

• custom Filter Android won't show me the results

  - by TiGer

  Hi, I have been implementing a class which class extends ArrayAdapter and implements Filterable. The filtering part (in the performFiltering method()) seems to go ok, it fills the FilterResults object just as expected. But then I think I'm not doing it right on how to publish the results, atm I have : protected void publishResults(CharSequence prefix, FilterResults results) { // NOTE: this function is *always* called from the UI thread. subItems = (Vector)results.values; notifyDataSetChanged(); } But this simply won't "populate" my List with the received data. So now my question is how do I populate my List with the received results ? Do I have to do that programmatically ?

• Best way to set a default button (or trigger its event in javascript) for an input field, not part of a form

  - by Sheldon Pinkman

  I've got a stand-alone input field, not part of any form. I also got a button, that has some onclick event. When I type something in the input field, and press the Enter key, I want it do effectively press the button, or trigger its onclick event. So that the button is "the input field's default button" so to speak. <input id='myText' type='text' /> <button id='myButton' onclick='DoSomething()'>Do it!</button> I guess I can mess around with the input field's onkeypress or onkeydown events and check for the Enter key, etc. But is there a more 'clean' way, I mean something that associated the button with that input field, so that the button is the 'default action' or something for that field? Note that I'm not inside a form, I am not sending, posting, or submitting something. The DoSomething() function just changes some of the HTML content locally, depending on the text input.

• Correct Path for Git Remote Add from Amazon EC2 Instance to OSX Client Machine

  - by filmnut

  I'm trying to do a git remote add from a repository that sits on a remote Amazon AMI back to a cloned copy of the SAME repository that is sitting on my local OSX machine. I'm confused about what file path to use. I assume it's something like: git remote add my_clone <OSX_User_Name>@<OSX_HOST_NAME>:<PATH_TO_CLONED_REPO> I obviously know what my <OSX_User_Name> is, and I can figure out my <PATH_TO_CLONED_REPO>, but I have no idea how to determine a <OSX_HOST_NAME> that would actually work. Can I just put in my external IP address, followed by my machine's internal IP address? (Note that I'm working behind a router.) Is ssh:// the correct protocol? Do I need to set up ssh access from the Amazon EC2 machine to the local OSX machine?

• Will Windows Update modify anything in Visual Studio?

  - by Martin

  (Note: Yes, the technical side of this question seems to be rather SuperUser, but the implications are more relevant for StackOverflow readers.) As the title says, we are wondering if (fully) enabling automated Windows Updates on our developer machines will have implications for MS Visual Studio. That is, will any fixes to any components (be it libraries, UI/IDE, compiler, ...) ever be updated through Windows Update? We want to have 100% exact and reproducible development environments (wrt C++) on all developer machines, and so we are concerned that automated Windows updates may introduce some uncontrolled updates into our development chain.

• WFP Validation & IDataErrorInfo

  - by Jefim

  A note - the classes I have are EntityObject classes! I have the following class: public class Foo { public Bar Bar { get; set; } } public class Bar : IDataErrorInfo { public string Name { get; set; } #region IDataErrorInfo Members string IDataErrorInfo.Error { get { return null; } } string IDataErrorInfo.this[string columnName] { get { if (columnName == "Name") { return "Hello error!"; } Console.WriteLine("Validate: " + columnName); return null; } } #endregion } XAML goes as follows: <StackPanel Orientation="Horizontal" DataContext="{Binding Foo.Bar}"> <TextBox Text="{Binding Path=Name, ValidatesOnDataErrors=true}"/> </StackPanel> I put a breakpoint and a Console.Writeline on the validation there - I get no breaks. The validation is not executed. Can anybody just press me against the place where my error lies?

• python win32api registery key change

  - by user340495

  Hi, I am trying to trigger an event every time a registry value is being modified. import win32api import win32event import win32con import _winreg key = _winreg.OpenKey(_winreg.HKEY_CURRENT_USER,'Control Panel\Desktop',0,_winreg.KEY_READ) sub_key = _winreg.CreateKey(key,'Wallpaper') evt = win32event.CreateEvent(None,0,0,None) win32api.RegNotifyChangeKeyValue(sub_key,1,win32api.REG_NOTIFY_CHANGE_ATTRIBUTES,evt,True) ret_code=win32event.WaitForSingleObject(evt,3000) if ret_code == win32con.WAIT_OBJECT_0: print "CHANGED" if ret_code == win32con.WAIT_TIMEOUT: print "TIMED" my problem is that this is never triggered , the event always time-out. (the reg key I am trying to follow is the wallpaper) [ please note I trigger the event by 1) manually changing the registry value in regedit 2) an automated script which run this : from ctypes import windll from win32con import * windll.user32.SystemParametersInfoA(SPI_SETDESKWALLPAPER, 0,"C:\wall.jpg",SPIF_UPDATEINIFILE | SPIF_SENDWININICHANGE) ] Thanks for any help in advance :) EDIT:: sorry about formatting
