• Removing $_SESSION['layout']['action'] globally from all users!

  - by sologhost

  Ok, I am storing a session variable like so to load up users layouts faster if it's set instead of calling the database. But since the layout can be changed via the Administrator, I'd like to be able to globally remove all sessions where $_SESSION['layout']['action'] is set for all users. $_SESSION['layout']['action'] = array(a ton of indexes and mulit-dimensional arrays); Now, I know it's being stored into my database sessions table, there's a column for session_id, last_update, and data. So, question I have is how to remove that session array key ['action'] from all users. Using $_SESSION = array(); session_destroy(); Does not work. Basically, session_start() is being loaded on every page load, so I just want to remove all ['action'] keys from ['layout']. Is this possible to do? Thanks

• Access DoCmd.OpenForm Not Working

  - by user961743

  Looking for a second set of eyes to figure out my problem with an Access form filter. I created a search form, when filled in, appends search criteria to a string variable (strQuery) that is put in place to the [WhereCondition] for opening a form. However, when the script is ran, nothing comes up except for a filtered form with no records. Here is the line that opens the form: DoCmd.OpenForm "ADD_NEW_NCMR", , , strQuery Before the line is ran, strQuery equals: 1=1 AND [NCMR].[NCMR_NUM] = '12-129' The form name, and table.column combination are all correct. In fact, using the DCount function returns the result of 1, which is correct for this query, and returns the correct number for other queries as well. This makes me think that there is nothing wrong with the where condition. DCount("[NCMR_NUM]", "NCMR", strQuery)

• When should I use static methods in a class and what are the benefits?

  - by NAVEED

  I have concept of static variables but what are the benefits of static methods in a class. I have worked on some projects but I did not make a method static. Whenever I need to call a method of a class, I create an object of that class and call the desired method. Static variable in a method holds it's value even when method is executed but accessible only in its containing method but what is the best definition of static method? Is calling the static method without creating object of that class is the only benefit of static method? What is the accessible range for static method? What is the syntax to create and calling static method in php? Thanks

• Compilation error on a user control

  - by MikeP

  I'm stumped! We have a user control for managing account information. We use this particular control on two pages. On one page, everything works perfectly and meets our expectation. On the second page however we receive compilation errors stating that: "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\lrpcentral\0e987bea\6719c8b6\App_Web_PageThatFails.aspx.f3d462c1.oi52bvii.0.cs(172): error CS0433: The type 'xxxx_ascx' exists in both 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\APPLICATIONNAME\0e987bea\6719c8b6\App_Web_xxxx.ascx.cdcab7d2.xbnvt2za.dll' and 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\APPLICATIONNAME\0e987bea\6719c8b6\App_Web_eix7xllr.dll' My problem is similar to Cyril's but the "delete everything from Temp" is not an option for me, and Cyril's solution does not apply since the only variable we have is contained in the designer file, which is not deployed to our production environment (we pre-compile). After reading David's answer (here) I examined my directories for circular dependency and was unable to find any. Structure: Top Level Page that works Control Directory A Page that causes the error

• Dynamically formatting a string

  - by TofuBeer

  Before I wander off and roll my own I was wondering if anyone knows of a way to do the following sort of thing... Currently I am using MessageFormat to create some strings. I now have the requirement that some of those strings will have a variable number of arguments. For example (current code): MessageFormat.format("{0} OR {1}", array[0], array[1]); Now I need something like: // s will have "1 OR 2 OR 3" String s = format(new int[] { 1, 2, 3 }); and: // s will have "1 OR 2 OR 3 OR 4" String s = format(new int[] { 1, 2, 3, 4 }); There are a couple ways I can think of creating the format string, such as having 1 String per number of arguments (there is a finite number of them so this is practical, but seems bad), or build the string dynamically (there are a lot of them so this could be slow). Any other suggestions?

• Public property List needs to Concat 2 types with inheritance

  - by Bernard

  I have 2 lists: one of type A and one of type Aa. type Aa is inherited from type A. So: List<A> listA = new List<A>(); List<Aa> listAa = new List<Aa>(); with class Aa : A I have: public property Lists<A> { get { List<A> newList = new List<A>(); //return concat of both lists foreach(List l in listA) { newList.Add(l); } foreach(List l in listAa) { newList.Add(l); } } Can I somehow use Concat instead of the foreach loop? i.e. get { return listA.Concat(listAa); } // this doesn't work And secondly, how do I do the set part of the property? set { //figure out the type of variable value and put into appropriate list? }

• Use LINQ and C# to make a new List from an old List

  - by Addie

  This should be pretty simple, but I am new at LINQ. I have a List of FillList structs. I'd like to use LINQ to create a new List where instead of having the number of buys and sells, I would have one variable containing the sum. For example, if the FillStruct structure has buy = 4 and sell = 2 then the NewFillStruct structure will have numlong = 2. If the FillStruct structure has buy = 2 and sell = 4 then the NewFillStruct structure will have numlong = -2. Here are the structures. struct FillStruct { int buy; int sell; string date; } struct NewFillStruct { int numlong; string date; }

• Issues using ivy

  - by Almas

  Hi, I am new bie to ivy. I am using packager resolver and that packager resolver resolves the zip file, unzip it, extracts the jar file from it in temp build file, but it stays temporarily and only the jar file which i specified as a module name gets copied to destination rest of all are ignored. Is there a way i can get all the jar files? I use preseverBuildDirectories but is there a better way to do it? Also is it possible for me to publish an artifact to svn using normal ivy? I got error while i was trying to use ivy 2.1.0 on XP using ant 1.8.0 java.illegalArguementException saying authorization failed. Is there a way i can work through ivy:publish? Is there a way i can use ivy variable in packager.xml? Thanks in advance, Almas

• How to convert a gi-normous integer (in string format) to hex format? (C#)

  - by eviljack

  Given a potentially huge integer value (in c# string format), I want to be able to generate it's hex equivalent. Normal methods don't apply here as we are talking arbitrarily large numbers, 50 digits or more. The techniques I've seen which use a technique like this: // Store integer 182 int decValue = 182; // Convert integer 182 as a hex in a string variable string hexValue = decValue.ToString("X"); // Convert the hex string back to the number int decAgain = int.Parse(hexValue, System.Globalization.NumberStyles.HexNumber); won't work because the integer to convert is too large. For example I need to be able to convert a string like this: 843370923007003347112437570992242323 to it's hex equivalent. these don't work: http://stackoverflow.com/questions/1139957/c-convert-int-to-hex-and-back-again http://stackoverflow.com/questions/74148/how-to-convert-numbers-between-hex-and-decimal-in-c

• Admin section in CakePHP

  - by Nicklas Ansman

  I'm having a hard time understanding how the CakePHP admin system works. Should all controllers who has an action which requires login include AuthComponent or just the one who handles the login/logout? Let's say I want to protect the add action of a controller. First I create admin_add() in the controller and then in the beforeFilter() method I check if $this->Session->check('Auth.User') is set a redirect based on this? Turns out it was better to just controll this with $this->Auth->allow() What is the easiest way to return to the URL the user was trying to access? Is there a better way than setting a session variable? Turns out it does this automagically :) If someone has a good tutorial for this I would happily read it :) I've already read this tutorial but I found it to be a little to basic and the CakePHP-docs are not that great on this topic either.

• a java applet question

  - by Robert

  Hello there. I have a question on the java applet.I've created a java applet,which is a board game,that can have a 2*2 array with row number and column number both set to 9 by default. Now I want to extend my applet a bit,that the user can specify the size they want on the command-line,then the applet class will create an applet with correspoding size. I try to add a constructor in the applet class,but the Eclipse complains,I also tried another class,which will create an instance of this applet with size as an instance variable,but it is not working. Could anyone help me a little bit on where to put a main() method that can take care of user-specified board sized,then create an array in my applet class accordingly? Thanks a lot. Rob

• Flex 4.6 Mobile - Scrolling to the last added item in a dataGrid with variableRowHeight

  - by user1305331

  I'm trying to set the scroll vertical position of a spark dataGrid to show the items as I add them to the grid. I know you can set the scroll position like this: dataGrid.scroller.viewport.verticalScrollPosition = itemPosition*rowHeight; The problem is that the dataGrid have variableRowHeight, as each row word wraps their name labels, and I don't know how to get each row height. I though of getting the itemRenderer associated with every item as I add it to the grid, and keep the total row height value in a variable, but don't know how to achieve that. Is there any way to set the scroll position of a dataGrid with variableRowHeight to show the last added item?

• Master report and subreport communication

  - by Dave Jarvis

  How do you determine whether the content for the detail page being displayed is filled by a specific subreport? For example, consider two subreports on the same master report, using different detail bands: Detail 1 Detail 2 The header on the master report should show certain fields on pages where the subreport in the Detail 2 band is printed. A Return Value from the subreport in the Detail 2 band only seems to be set after the report has finished, even though the Reset type for the variable (in both the master and the subreport) is set to Page. (Setting it to Report also does not help.)

• conditional operator in C question

  - by Seephor

  I just have a quick question about the conditional operator. Still a budding programmer here. I am given x = 1, y = 2, and z = 3. I want to know, why after this statement: y += x-- ? z++ : --z; That y is 5. The values after the statement are x = 0, y = 5, and z = 4. I know the way the conditional operator works is that it is formatted like this: variable = condition ? value if true : value if false. For the condition, y += x-- , how does y become 5? I can only see 2 (2 += 0) and 3 (2 += 1)(then x-- becomes zero) as possibilities. Any help is much appreciated. :)

• MovieClip.onResize event? how?

  - by Phil

  I have a an swf, called 'controls' that I created with flash cs4. I upload the controls.swf to my web server. I create an application in flex and it loads the external swf controls into itself. So far I can manipulate the controls.swf via my flex app. I created a class in my external swf, but I need to add some onResize event/check to my scroll bar. For example, if my scrollbar size increases/decreases, I want it to change variable values. Is there some movieClip.onResize event?

• Cannot call scalar-valued CLR UDF from select ... from table statement

  - by Henrik B

  I have created a scalar-valued CLR UDF (user defined function). It takes a timezone id and a datetime and returns the datetime converted to that timezone. I can call it from a simple select without problems: "select dbo.udfConvert('Romance Standard Time', @datetime)" (@datetime is of course a valid datetime variable) But if I call it passing in a datetime from a table it fails: "select dbo.udfConvert('Romance Standard Time', StartTime) from sometable" (column StartTime is of course a column of type datetime) The error message is: "Cannot find either column "dbo" or the user-defined function or aggregate "dbo.udfConvert", or the name is ambiguous." This message is really for beginners that has misspelled something, but as it works in one case and not in the other, I don't think I have done any misspellings. Any ideas?

• abandon session in asp.net on browser close..kill session cookie

  - by Tuviah

  So I have a website where I use session start and end events to track and limit open instances of our web application, even on the same computer. On page unload i call a session enabled page method which then called session.abandon. This triggers session end event and clears the session variable but unfortunately does not kill the session cookie!! as a result if other browser instances are open there are problems because their session state just disappeared...and much worse than this when I open the site again with the zombie session still not expired, I get multiple session start and session end events on any subsequent postbacks. This happens on all browsers. so how do I truly kill the session (force the cookie to expire)

• "dynamic" keyword and JSON data

  - by Peter Perhác

  An action method in my ASP.NET MVC2 application returns a JsonResult object and in my unit test I would like to check that the returned JSON object indeed contains the expected values. I tried this: 1. dynamic json = ((JsonResult)myActionResult).Data; 2. Assert.AreEqual(JsonMessagesHelper.ErrorLevel.ERROR.ToString(), json.ErrorLevel); But I get a RuntimeBinderException "'object' does not contain a definition for 'ErrorLevel'". However, when I place a breakpoint on line 2 and inspect the json dynamic variable (see picture below), it obviously does contain the ErrorLevel string and it has the expected value, so if the runtime binder wasn't playing funny the test would pass. What am I not getting? What am I doing wrong and how can I fix this? How can I make the assertion pass?

• How do I keep the width of a table constant when it has dynamic content?

  - by Lincoln Bergeson

  How do I keep the width of a table constant, even when the content of that table is interactively changing? Old Post: How do I insert a variable length tab in HTML? I want certain dynamic fields in my table to line up but they're changing width constantly. EDIT: What I mean is this: in any text editor I can press tab to align certain bits of text, and not care about how many spaces there are. In fact, the number of spaces there needs to be for the leftmost part of the text can change, and I still won't care, as long as the text lines up. How do I do this is in HTML?

• Django: accessing session variables from within a template?

  - by AP257

  Hi all If I set a session variable in Django, like: request.session["name"] = "name" Is there a way I can access it from within a template, or do I have to retrieve it from within a view, and then pass it to a template? Asking because I have around 10 little session variables that I'd like to access within a template, and passing all 10 from the view to the template could get a bit messy. (I have to use session variables because it's a HttpResponseRedirect, but storing the variables in a database is overkill for my purposes.) So - any way to grab session variables directly within a template?

• How do you move html from one div to another with Jquery without breaking javascript

  - by KallDrexx

  I have two divs for different sections of my webpage, a working and a reference section. One is fixed size, the other is variable sized and they are vertically stacked. I am trying to design it so that if you want to work on something in the reference pane, you click a link and it swaps all the data between the two panes. My idea was to do the following: var working = $("#working_pane").html(); var ref = $("#reference_pane").html(); $("#working_pane").html(ref); $("#reference_pane").html(working); The problem with this, is it seems that any javascript referenced inside of these panes (for example, in place editors) get broken upon switching. No javascript errors occur, it's just that nothing happens, like the javascript ties are broken. Is there any to move the html without breaking the javascript contained?

• When do you trust the data / variables

  - by Wizzard

  We all know that all user data, GET/POST/Cookie etc etc needs to be validated for security. But when do you stop, once it's converted into a local variable? eg if (isValidxxx($_GET['foo']) == false) { throw InvalidArgumentException('Please enter a valid foo!'); } $foo = $_GET['foo']; fooProcessor($foo); function fooProcessor($foo) { if (isValidxxx($foo) == false) { throw Invalid...... } //other stuff } To me thats over the top. But what if you load the value from the database... I hope I make sense :)
