• How do I include 2 tables in one LocalStorage item?

  - by Noor

  I've got a table that you can edit, and I've got a simple code saving that list when you're done with editing it. (the tables have the contenteditable on) The problem I've stumbled upon is that if I double click on enter, the table gets divided into two separate tables with the same ID. This causes the code I'm using to set the localStorage to only store one of the tables (I assume the first).. I've thought of different solutions and I wonder if someone could point out the pro's and con's (if the solutions even works that is). Make a loop that checks the page after tables and stores them into an array of localStorage-items.. I'd have to dynamically create a localStorage item for each table. Take the whole div that the tables are in, and store that in the localStorage, when a user revisits the page, the page checks after the items in storage and displays the whole divs. Any suggestions you have that can beat this :).. (but no cache, it has to be with the localStorage!) Thanks

• Question regarding built-in type variable is returned from a function

  - by Chan

  Hello, If a local object is returned in a function call, it has to do at least three steps: 1. Copy constructor is called to hold a copy. 2. Destroy local object. 3. A copy is return. For example: x = y + z If x is an integer object. A copy of y + z should be returned, then a new object is created, then assignment operator of x will take this object as parameter. So my question is: Is the same process used for built-in type such as int, double...? If they're not the same, how's it done? Thanks, Chan

• The system cannot find the path specified with FileWriter

  - by Nazgulled

  Hi, I have this code: private static void saveMetricsToCSV(String fileName, double[] metrics) { try { FileWriter fWriter = new FileWriter( System.getProperty("user.dir") + "\\output\\" + fileTimestamp + "_" + fileDBSize + "-" + fileName + ".csv" ); BufferedWriter csvFile = new BufferedWriter(fWriter); for(int i = 0; i < 4; i++) { for(int j = 0; j < 5; j++) { csvFile.write(String.format("%,10f;", metrics[i+j])); } csvFile.write(System.getProperty("line.separator")); } csvFile.close(); } catch(IOException e) { System.out.println(e.getMessage()); } } But I get this error: C:\Users\Nazgulled\Documents\Workspace\Só Amigos\output\1274715228419_5000-List-ImportDatabase.csv (The system cannot find the path specified) Any idea why? I'm using NetBeans on Windows 7 if it matters...

• Compile Error Using MutableClassToInstanceMap with Generics

  - by user298251

  I am getting the following compile error "The method putInstance(Class, T) in the type MutableClassToInstanceMap is not applicable for the arguments (Class, Number)" on the putInstance method call. Does anyone know what I am doing wrong?? Thanks! public class TestMutableClassToInstanceMap { public final MutableClassToInstanceMap<Number> identifiers = MutableClassToInstanceMap.create(); public static void main(String[] args) { ArrayList<Number> numbers = new ArrayList<Number>(); numbers.add(new Integer(5)); TestMutableClassToInstanceMap test = new TestMutableClassToInstanceMap(numbers); } public TestMutableClassToInstanceMap(Collection<Number> numbers){ for (Number number : numbers) { this.identifiers.putInstance(number.getClass(), number); //error here } this.identifiers.putInstance(Double.class, 5.0); // This works } }

• How can I make XOR work for logical matrix in MATLAB?

  - by Runner

  >> XOR(X,X) ??? Undefined function or method 'XOR' for input arguments of type 'logical'. Why XOR can't be used for logical matrix? And I tried a more simple example: >> A=[1 0;1 0]; >> B=[1 1;0 0]; >> XOR(A,B) ??? Undefined function or method 'XOR' for input arguments of type 'double'. How can I properly use XOR?

• WPF DependencyProperty event before content changed

  - by morsanu

  First I will explain the context of the problem, because you might be able to point me in a better direction. I need to implement a undo-redo like system on an object. The object has a series of dependency properties. Some are double, int, string but some are also of DependencyObject type. I need to save the value of the property before it is changed, and for this I added the CoerceValueCallback. public static readonly DependencyProperty MyBackgroundProperty = DependencyProperty.Register("MyBackground", typeof(MyCustomizableBackground), typeof(MyComponent), new UIPropertyMetadata(default(MyCustomizableBackground), null, new CoerceValueCallback(OnPropertyChanged))); In OnPropertyChanged I save the value before it's changed. MyCustomizableBackground is the DependencyObject that has also some dependency properties. The problem is that in this case, where I have a custom object as a property, the OnPropertyChanged method isn't triggered, but when I have a common type, it is triggered.

• Permanent remove of logo in Windows Scripting Host (WSH() scripts.

  - by antonio

  I know two ways to remove the logo permanently. The "official" one: cscript //Nologo //S Will save current command line options for current user. A ftype approach with admin privileges: ftype wsffile="%SystemRoot%\System32\CScript.exe" //nologo "%%1" %%* ftype jsfile="%SystemRoot%\System32\CScript.exe" //nologo "%%1" %%* ftype vbsfile="%SystemRoot%\System32\CScript.exe" //nologo "%%1" %%* Double-%'s are needed only if you use the lines in a batch file. The latter will all users via affect the reg key HKEY_CLASSES_ROOT\<file>\Shell\Open\Command, where <file> can be wsffile, jsfile or vbsfile. Do you know where are stored the cscript //Nologo //S settings?

• Visual Studio 2008. MFC event wizard broken

  - by G Forty

  OK, so it's almost a programming question - The VS2008 dialog event wizard has stopped working. Double-clicking on a button in an MFC dialog project does not fire the wizard as usual and a right-click to get to the 'Add Event Handler...' shows a dialog with no message types. Further to this the MFC message mapping and virtual class listing that generally appears in the properties window (Alt + Enter) is now empty. Has anyone elese seen this and if so, how'd they fix it? I have 'repaired' my VS08 installation ... Thx++ Jerry

• How do I get a Mac ".command" file to automatically quit after running a shell script?

  - by LOlliffe

  In my shell script, my last lines are: ... echo "$l" done done exit I have Terminal preference set to "When the shell exits: Close the window". In all other cases, when I type "exit" or "logout", in Terminal, the window closes, but for this ".command" file (I can double-click on my shell script file, and the script runs), instead of closing the window, while the file's code says "exit", what shows on the screen is: ... $l done logout [Process completed] ...and the window remains open. Does anyone know how to get a shell script to run, and then just automatically quit the Terminal window on completion? Thanks!

• How do I check the validity of the Canadian Social Insurance Number in C#?

  - by user518307

  I've been given the assignment to write an algorithm in C# that checks the validity of a Canadian Social Insurance Number (SIN). Here are the steps to validate a SIN. Given an example Number: 123 456 782 Remove the check digit (the last digit): 123456782 Extract the even digits (2,4,6,8th digith): 12345678 Double them: 2 4 6 8 | | | | v v v v 4 8 12 16 Add the digits together: 4+8+1+2+1+6 = 22 Add the Odd placed digits: 1+3+5+7 = 16 Total : 38 Validity Algorithm If the total is a multiple of 10, the check digit should be zero. Otherwise, Subtract the Total from the next highest multiple of 10 (40 in this case) The check digit for this SIN must be equal to the difference of the number and the totals from earlier (in this case, 40-38 = 2; check digit is 2, so the number is valid) I'm lost on how to actually implement this in C#, how do I do this?

• Devision in c# not going the way i expect

  - by Younes

  Im trying to write something to get my images to show correctly. I have 2 numbers "breedtePlaatje" and "hoogtePlaatje". When i load those 2 vars with the values i get back "800" and "500" i expect "verH" to be (500 / 800) = 0,625. Tho the value of verH = 0.. This is the code: int breedtePlaatje = Convert.ToInt32(imagefield.Width); int hoogtePlaatje = Convert.ToInt32(imagefield.Height); //Uitgaan van breedte plaatje if (breedtePlaatje > hoogtePlaatje) { double verH = (hoogtePlaatje/breedtePlaatje); int vHeight = Convert.ToInt32(verH * 239); mOptsMedium.Height = vHeight; mOptsMedium.Width = 239; //Hij wordt te klein en je krijgt randen te zien, dus plaatje zelf instellen if (hoogtePlaatje < 179) { mOptsMedium.Height = 179; mOptsMedium.Width = 239; } } Any tips regarding my approach would be lovely aswell.

• Custom control in DataViewGrid

  - by Winston

  I'm trying to embed a custom control in a Datagridview. I've looked at the Calendar (http://msdn.microsoft.com/en-us/library/7tas5c80.aspx) example but i just cant get it working for a custom control. I need the control to show for each object in the grid. Not just when the user edits the content. I need to do this so that i can bind my dataviewgrid to a datasource and have it create the required forms in the grid for each my object list. So that the user can do inline editing in the grid without having to double click the row and have a new dialog pop up. Any help would be greatly appreciated.

• Chipmunk warning still present with --release

  - by Kaliber64

  I'm using Python27 on Windows 7 64-bit. I downloaded the source for Chipmunk 6.2.x and compiled Pymunk with --release and -c ming32. Almost zero problems. Lots of path not found cause I'm bad. All prints seem to have disappeared but I get spammed with EPA iteration warnings. I've seen a couple discussions but no solutions. Possible chipmunk betas to fix the float errors causing the double truths causing the warning. I picked the latest stable version I think. My program is seriously bogged down with all the prints. class NullDevice(): def write(self, s): pass sys.stdout=NullDevice() Does not disable the C prints .< Any help?

• Flex Datagrid File Download old value

  - by Vish

  Hi, We use a AIR client and WAMP server. Got a weird issue with Flex datagrid. When I download an image by double clicking on a datagrid row, the file gets downloaded correctly. But when I go on to select another row for download, even though the correct parameters are being passed, it again prompts download of old file. Upon cancelling that and trying again, it picks up the selected row. Not sure how to fix this issue, below is the datagrid code I am using, <mx:DataGrid x="10" y="10" id="ourDataGrid" visible="true" enabled="true" dataProvider="{fileList}" verticalScrollPolicy="on" selectionColor="#B7C6E7" itemClick="downloadFile(event)"> <mx:columns> <mx:DataGridColumn headerText="Name" dataField="@name" /> <mx:DataGridColumn headerText="LastName" dataField="@lastname" /> <mx:DataGridColumn headerText="FirstName" dataField="@firstname" /> </mx:columns> </mx:DataGrid>

• negative precision values in ostream

  - by daz-fuller

  This is more of a question of curiosity but does anyone know how negative precision values are handled in C++? For example: double pi = 3.14159265; cout.precision(-10); cout.setf(ios::fixed, ios::floatfield); cout << pi << endl; I've tried this out and using GCC and it seems that the precision value is ignored but I was curious if there is some official line on what happens in this situation.

• Why aren't Admob click callback delegate methods getting called?

  - by executor21

  I'm integrating the latest version of the admob sdk (version 20100412) into my app. The ads get displayed, but I need the app to make some changes when an ad is clicked and admob displays a full-screen browser. However, none of the callback methods (willPresentFullScreenModal, didPresentFullScreenModal, willDismissFullScreenModal, and didDismissFullScreenModal) are called, even though other delegate methods are. Why aren't these callbacks being made? They were in the previous versions of the SDK, and the sample app doesn't use them, so it's no help. EDIT: removed the double negative from the question title

• .NET Process.Start() on an executable on a remote system - security warning?

  - by BrettRobi

  I've created a Windows Service that accepts commands from remote machines via WCF. One of those commands is to run a specified executable (let's ignore the security implications of such functionality). In my Service I am using Process.Start() to run the executable. All works well if the executable is local to the machine, but if it is on a remote file share it is failing with no error (or more accurately just hanging). I suspect the problem is that it is triggering the standard Windows 'Unverified Publisher' warning that one would see if they double click an exe on a remote system. Is there any way I can bypass this from my service so that I can truly run any executable? As I said I understand the security implications of allowing it to run any executable, but this is really what I need. I would have thought this warning was only a user mode concept, but it really does seem to be getting in the way of my Service. Ideas?

• Naming convention in Objective C /C , start with "_"?

  - by Tattat

  Something I see ppl define the variable like this: b2World *_world; b2Body *_body; CCSprite *_ball; instead of b2World *world; b2Body *body; CCSprite *ball; I familiar with the second one, but not the first one. So, I checked the Wikipedia about naming convention: Names beginning with double underscore or an underscore and a capital letter are reserved for implementation (compiler, standard library) and should not be used (e.g. __reserved or _Reserved). So, is that any special meaning which is start with "_"? The wiki page.

• Zero division does not throw exception in nunit

  - by Boris

  Running the following C# code through NUnit yields Test.ControllerTest.TestSanity: Expected: <System.DivideByZeroException> But was: null So either no DivideByZeroException is thrown, or NUnit does not catch it. Similar to this question, but the answers he got, do not seem to work for me. This is using NUnit 2.5.5.10112, and .NET 4.0.30319. [Test] public void TestSanity() { Assert.Throws<DivideByZeroException>(new TestDelegate(() => DivideByZero())); } private void DivideByZero() { // Parse "0" to make sure to get an error at run time, not compile time. var a = (1 / Double.Parse("0")); } Any ideas?

• How do you keep yourself and your co-workers from creating huge classes

  - by PieterG

  Stackoverflow users, How do you keep yourself from creating large classes with large bodied methods. When deadlines are tight, you end up trying to hack things together and it ends up being a mess which would need to be refactored. For me, the one way was to start with test driven development and that lends itself to good class design as well as the SRP (Single Responsibility Principle). I also see developers just double clicking on controls and typing out line after line in the event method that gets fired. What are your suggestions?

• Mac OS X: How to change word separator characters?

  - by avetis.kazarian

  Depending on your system, the word separator characters change the way you can select/delete a word (e.g. by double clicking on it or using a key combination with your keyboard). The fact is that I hate the default behavior of OSX. For example: Take the following line of code: obj.attr1.innerAttr. If my cursor is at the end of the line and I press alt + backspace, it will delete everything and not just innerAttr. I only found some apps (like iTerm) which let you change the word separator characters. Is there a way to change it for the whole system?

• What useful macros have you created in Netbeans?

  - by Richard Poirier

  I use Netbeans (nightly build) for Ruby on Rails development and I'm looking to beef up my macros. I've created a few myself: copy identifier: select-identifier copy-to-clipboard paste clipboard over identifier: select-identifier paste-from-clipboard double quote element select-element-next "\"" single quote element: select-element-next "'" But I'm looking for other useful ones and Google is giving me nothing. The record macro feature usually doesn't work too well so I'd rather just "write" the macros myself but I can't even find a reference that lists what commands (like "select-identifier") are actually available. Any Netbeans macro gurus out there?

• formatting NSArray

  - by califguy

  So from the code below, I have managed to get the string *tempstring into an array chunk. Now chunk[0] contains 'a' while chunk[1] contains 'aa'. I am trying to format chunk[0] to '0a' which I can using the replaceObjectAtIndex method. Here's my question: How do I detect that chunk[0] is formatted as 'a' and not '0a'. I want to check all the indexes and make sure they have double digits and if not use a 0 to prefix it. NSString *tempstring = @"a-aa-bb"; NSMutableArray *chunk = [tempstring componentsSeparatedByString: @"-"]; NSLog(@"%@",[chunk objectAtIndex:0]);

• What is the most EVIL code you have ever seen in a production enterprise environment?

  - by Registered User

  What is the most evil or dangerous code fragment you have ever seen in a production environment at a company? I've never encountered production code that I would consider to be deliberately malicious and evil, so I'm quite curious to see what others have found. The most dangerous code I have ever seen was a stored procedure two linked-servers away from our core production database server. The stored procedure accepted any NVARCHAR(8000) parameter and executed the parameter on the target production server via an double-jump sp_executeSQL command. That is to say, the sp_executeSQL command executed another sp_executeSQL command in order to jump two linked servers. Oh, and the linked server account had sysadmin rights on the target production server.

• Why am I getting "Enter Parameter Value" when running my MS Access query?

  - by DanM

  In my query, I use the IIF function to assign either "Before" or "After" to a field named BeforeOrAfter using AS. When I run this query, however, the "Enter Parameter Value" dialog appears, requesting a value for BeforeOrAfter. If I remove BeforeOrAfter DESC from the ORDER BY clause, I don't get the dialog. Here is the offending query: SELECT d.Scenario, e.Event, IIF(d.LogTime < e.Time, 'Before','After') AS BeforeOrAfter, d.HeartRate FROM Data d INNER JOIN Events e ON d.Scenario = e.Scenario WHERE e.Include = Yes ORDER BY d.Scenario, e.Id, BeforeOrAfter DESC Question: Why is my AS BeforeOrAfter not being recognized by the ORDER BY clause? Why does it ask me to enter a parameter value for "BeforeOrAfter" when I run this query? Note: I tried using brackets, single quotes, double quotes, etc., but none of that made any difference.
