• I want to prevent people from accessing my php pages directly using .htaccess

  - by asdasdasd

  I have a site that is made up of php pages, but they are served to the user through includes based on what I think they need. if they can guess the name of a php file, they can access those pages. while this is not a security risk at all, i would rather have a way to catch this and redirect them to somewhere else. i really want everything to go through the index page unless it is a file that exists (exeption being for any file ending with .php). I tried this, didnt work: RewriteEngine on RewriteCond %{REQUEST_URI} !(.*\.php$) [NC] RewriteCond %{REQUEST_FILENAME} !-f [NC] RewriteRule .* /n/index.php [NC]

• Why does Apple use Objective-C for iPhone development? (App Store)

  - by Luca Matteis

  I'm interested to know your opinion on why Apple uses a language such as Objective-C for app development. Does Apple's app store allow apps written only in this language? Does apple even look at your source-code or does it just care of the binary output? I learned that most of their app rejection (in the app store) is based upon apps crashing (probably memory leaks in which Objective-c is not very efficient unless you use a GC). Why not let developers use a safer language, like a scripting language? I think these are important questions for a developer (I don't even use Apple's products) because it seems like Apple's app store is the MOST successful app sale place on the web.

• javascript - Google Chrome cluttering Array generated from .split()

  - by patrick

  Given the following string: var str = "one,two,three"; If I split the string on the commas, I normally get an array, as expected: var arr = str.split(/\s*,\s*/); Trouble is that in Google Chrome (for Mac), it appends extra properties to the array. Output from Chrome's debugger: arr: Array 0: one 1: two 2: three constructor: function Array() index: undefined input: undefined length: 3 So if I iterate over the array with a for/in loop, it iterates over the new properties. Specifically the input and index properties. Using hasOwnProperty doesn't seem to help. A fix would be to do a for loop based on the length of the Array. Still I'm wondering if anyone has insight into why Chrome behaves this way. Firefox and Safari don't have this issue.

• iPhone real memory climbs when interacting with UI

  - by Scott Gress

  I've been using the Activity Monitor to check the memory usage of my iPhone apps. I've noticed that the Real Memory climbs whenever I interact with the UI in any way, even if there's no code being called. For example, I can create a brand new View-Based application and run it, and as I click or drag in the empty window the Real Memory increases even though the app isn't responding in any way. I get that the view controller is doing some stuff in the background to interpret my interactions, but it seems like the memory should go back down after a second or so. Instead, it keeps going up and up and up as long as I keep clicking or dragging. I can wait forever and it never decreases. This is a little disturbing. Am I missing something?

• "Refreshing" an XML feed on iPhone/Mac OSX

  - by Steve

  Hi all, I'm curious for those of you who are building iPhone apps based on REST/SOAP/XML-RPC or simply pulling down a dynamic XML feed, what does it mean exactly to you when a user says 'refresh' the feed? The straight forward way is to populate some collection, say an NSMutableArray, with whatever you bring down from the feed. If a widget on the UI is available to refresh, I typically do something like: [myMutableArray removeAllObjects]; // follow steps to repopulate myMutableArray It seems this is the least efficient algorithm for refreshing an XML feed. For instance many folks who are building Twitter clients, are appending changes to their existing feed, versus bringing down the entire feed in its complete form again. What kind of algorithms are you using to "refresh" your models when speaking to a server-side data source? Thanks all.

• What software or service can I use to programatically make phone calls with?

  - by Jason

  I'm looking to programatically make phone call reminders to customers based upon their opt-in requests. I am NOT a telemarketer. I need to make a phone call, and play a message. I need to leave a message after the beep if an answering machine or voicemail is detected. I need to know if the message was successfully delivered. Ideally, I could offer the user feedback by pressing a button and recording their selection. I prefer Windows and .NET but would consider anything. What do you suggest?

• Changing careers to Software Engineering.... Wise?

  - by Phil

  Hello everyone, I notice this site has a wealth of software professionals and I am investigating a career change to Software Engineering: *Particularly, I would like to know how likely one would be able to work from home or another country over the internet. Is this something that can be done and what does it usually entail? (time?,experience?, specific companies?, etc) *Currently, I am a teacher but always had a passion for tech. I am interested in a MS - Software Engineering program designed for individuals based from another field. Is this a wise degree to obtain? Would I be just wasting my time and money obtaining this degree? (I'm suspicious about this program and the feasibility of obtaining employment without a healthy CS background) Thanks for any assistance you can provide!

• Return from jQuery Ajax Method

  - by Lijo

  I have a button named searchReportButton. On this button click, I need to check session value from server using a ajax web method "Error.aspx/CheckSessionExpiry".This is done in checkSession javascript function. The checkSession is not returning anything now - instead it is handling the required operation based on the result (redirecting to error page). I need to return the result of ajax web method to the Main Caller. How can we do this return? Main Caller searchReportButton.click(function () { checkSession(); //Remainging Code }); Helper function checkSession() { var win = 101; $.ajax( { type: "POST", url: "Error.aspx/CheckSessionExpiry", data: '{"winNumber": "' + win + '"}', contentType: "application/json; charset=utf-8", dataType: "json", success: handleSessionResult } ); } Result Helper function handleSessionResult(result) { if (result.hasOwnProperty("d")) { result = result.d } if (result == "ACTIVE") { window.location.href("Error.aspx"); return false; } //alert(result); }

• C# how to sort a list without implementing IComparable manually?

  - by JL

  I have a fairly complex scenario and I need to ensure items I have in a list are sorted. Firstly the items in the list are based on a struct that contains a sub struct. For example: public struct topLevelItem { public custStruct subLevelItem; } public struct custStruct { public string DeliveryTime; } Now I have a list comprised of topLevelItems for example: var items = new List<topLevelItem>(); I need a way to sort on the DeliveryTime ASC. What also adds to the complexity is that the DeliveryTime field is a string. Since these structs are part of a reusable API, I can't modify that field to a DateTime, neither can I implement IComparable in the topLevelItem class. Any ideas how this can be done? Thank you

• Stand-alone app to enter records through forms?

  - by OverTheRainbow

  Hello I need to find a stand-alone (ie. no OpenOffice-based tools, for instance) Windows application that can present users with forms to enter records into an SQLite database. The goal is to migrate data from Excel sheets into a serverless, single-user database like SQLite. As a bonus, the application would also have a somewhat-protected admin section so that I can also use it to CRUD data with the same app, but it's not a requirement. There are a lot of applications listed on the official SQLite site: Can someone recommend one that is meant for end-users, either open- or closed-source? Thank you.

• Several ways to call a windows batch file from another one or from prompt. Which one in which case?

  - by dim

  A windows batch file (called.bat or called.cmd) can be called from another batch file (caller.bat or caller.cmd) or interactive cmd.exe prompt in several ways: direct call: called.bat using call command: call called.bat using cmd command: cmd /c called.bat using start command: start called.bat I'm quite in trouble to differentiate their intended usage based on their help text: when to use which one? e.g. why I might use 'call' command instead of direct call. What's different? I'm interested on some summary report that analyze all 4 possibilities (and others if any missing) from various point of views: recommended use cases for which they are designed to fit, process spawning, execution context, environment, return code processing. Note: I'm using Windows XP SP3.

• SP: Random Records, Fave Record, Plus Known Record, NO repetition.

  - by Munklefish

  Hi, Thanks to help from a lot of you guys ive been given the following code which works great. However ive realised ive missed an important bit of info out of the question and so have reposted here (with updated code) to clarify. The following code gets 5 random records from a table plus a further single record based on the users favourite as identified in a second table: CREATE PROCEDURE web.getRandomCharities ( @tmp_ID bigint --members ID ) AS BEGIN WITH q AS ( SELECT TOP 5 * FROM TBL_CHARITIES WHERE cha_Active = 'TRUE' AND cha_Key != '1' ORDER BY NEWID() ) SELECT * FROM q UNION ALL SELECT TOP 1 * FROM ( SELECT * FROM TBL_CHARITIES WHERE TBL_CHARITIES.cha_Key IN ( SELECT members_Favourite FROM TBL_MEMBERS WHERE members_Id = @tmp_ID ) EXCEPT SELECT * FROM q ) tc END However, i realised i also need to include the record where "cha_Key == '1'" if it isnt the same as the record returned in the second SELECT statement in the code shown above. HOpe that makes sense? THANKS!!!

• Should I pointer-cast from a private derived class to its base class?

  - by skydoor

  I found this from C++FAQ Generally, No. From a member function or friend of a privately derived class, the relationship to the base class is known, and the upward conversion from PrivatelyDer* to Base* (or PrivatelyDer& to Base&) is safe; no cast is needed or recommended. However users of PrivatelyDer should avoid this unsafe conversion, since it is based on a private decision of PrivatelyDer, and is subject to change without notice. How to understand the above words? I don't think the explanation is correct or accurate. I have a code like this class A{ }; class B: private A{ }; int main(){ B *b = new B(); A *a = new A(); a = b; //wrong a = (A*)b; //right }

• Please help me get my content div to get an auto height from absolutely positioned element

  - by Justin Hollender

  I need some help with a CSS layout. It is set up like this: +--------------------+ | | | header | |-| |--------------| | |nav| content | | | | | | | | | | | | | | footer | +--------------------+ So, the nav is supposed to be floating above all the main page content. That's why I have it set to be absolutely positioned. The issue is that the nav items are dynamic, without a set height. Right now, the nav expands past the content. How can I fix it so that the content will have an auto height based off the nav? Thanks in advance.

• How does windows resolves short names (8.3) into full names

  - by i3anshee

  I have a PC running 64 bit Windows Server 2003. There is a java application which uses cmd file as a launcher. The launcher does this SET JAVA_HOME= C:\Progra~1\Java "%JAVA_HOME%\bin\java" [java program execution line] Java is installed in C:\Program Files\Java. Since it is a x64 windows it also has C:\Program Files (x86)\ folder. Now the actual problem is that from time to time this application fails to start because it fails to find java. So the question is what windows does to resolve such ambiguity? Based on what it makes decisions about which folder to choose?

• A better way of representing File Attachment into a list(c#3.0)

  - by Newbie

  I have written List<Attachment> lstAttachment = new List<Attachment>(); //Check if any error file is present in which case it needs to be send if (new FileInfo(Path.Combine(errorFolder, errorFileName)).Exists) { Attachment unprocessedFile = new Attachment(Path.Combine(errorFolder, errorFileName)); lstAttachment.Add(unprocessedFile); } //Check if any processed file is present in which case it needs to be send if (new FileInfo(Path.Combine(outputFolder, outputFileName)).Exists) { Attachment processedFile = new Attachment(Path.Combine(outputFolder, outputFileName)); lstAttachment.Add(processedFile); } Working fine and is giving the expected output. Basically I am attaching the file to the list based on whether the file is present or not. I am looking for any other elegant solution than the one I have written. Reason: Want to learn differnt ways of representing the same program. I am using C#3.0 Thanks.

• Dynamic themes and custom styles

  - by Lawrence Kesteloot

  I've got an app with two themes (dark and light) that can be selected at runtime. This works. I also have a ListView with rows that can have one of three different layouts, each of which has a style (say, different colors). This also works. But I can't get these two features to work together. I really need six different styles, three for one theme (dark) and three for the other (light), but I can't figure out how to choose a style for a list item based on the current theme, or get that effect any other way by using XML files. My three layouts each point to a custom theme that sets the color, but that overrides whatever theme I've got set. Themes can only contain items that are "styleable", so I can't put my own custom items in there. There may be a way to do this programmatically, but I was hoping to do it declaratively. Any ideas?

• Is it possible to make a TListView search by the caption of a different column in Delphi?

  - by James

  Hi, When you set the Caption of a TListItem it seems to always set the Text for the first column in the row. When you start typing in the ListView it will search & select the closest match based on the caption of the first column. I have a situation where I need the caption of the first row to be empty, but still need the search functionality to work as normal (in this case the data I would be searching for may be in the 2nd/3rd column). Is this possible without using any 3rd party controls?

• JavaScript not changing display type or color in IE

  - by user445359

  I am trying to switch a series of blocks between "none" and "block" based on the OnMouseOver property and to change the title of the selected list to yellow at the same time. The JavaScript code I have for this is: function switchCat(cat) { var uls = document.getElementsByClassName('lower-ul'); var titles = document.getElementsByClassName('lower-cat-title'); for (var i=0;i<uls.length;i++) { uls[i].style.display = 'none'; titles[i].style.color = 'white'; } if (cat != -1) { var wanted = document.getElementById('lower-cat-'+cat); var wantedTitle = document.getElementById('lower-cat-title-'+cat); wanted.style.display = 'block'; wantedTitle.style.color = 'yellow'; } } It works with Chrome, Opera, and Firefox, however, it does not work with IE. When I test it in IE I get the error "Object doesn't support this property or method." Does anyone know what I am doing wrong?

• .NET DB Query Without Allocations?

  - by Michael Covelli

  I have been given the task of re-writing some libraries written in C# so that there are no allocations once startup is completed. I just got to one project that does some DB queries over an OdbcConnection every 30 seconds. I've always just used .ExecuteReader() which creates an OdbcDataReader. Is there any pattern (like the SocketAsyncEventArgs socket pattern) that lets you re-use your own OdbcDataReader? Or some other clever way to avoid allocations? I haven't bothered to learn LINQ since all the dbs at work are Oracle based and the last I checked, there was no official Linq To Oracle provider. But if there's a way to do this in Linq, I could use one of the third-party ones.
