  • Store #VALUE! #NUM! #REF! in variable.

    - by Ommit
    So a simple version of what I'm trying to do. Say I know there is an error in cell(1,1), furthermore I know it is either #num!, #ref! or #value!, I want to be able to store the respective error message in a variable, so I can print it to a different sheet. This is what I tried and it clearly failed. Sub FindAndPrintErrors dim Store as string If IsError(Range("A1"))) = True Then Store = Range("A1").value 'it breaks here' end if range("B1") = Store end sub I know I can do this but I wonder if there is a better way. Sub FindAndPrintErrors2 dim Store If IsError(Range("A1"))) = True Then temp = Range("A1").value 'it breaks here' if temp = "error 2029" then store = "#num!" ' and so on' end if range("B1") = Store end sub

  • Javascript, problem with binding an event to a div-tag

    - by Patrick
    Hello, i am trying to bind an event to a dynamically created div. function GameField(playerNumber) { this.fields = new Array(); this.player = playerNumber; this.isPlayerActive = false; this.currentRound = 0; } GameField.prototype.InitField = function(fieldNumber) { var newField = document.createElement("div"); if (fieldNumber == 0 || fieldNumber == 6 || fieldNumber == 8 || fieldNumber == 17) newField.className = 'gameCellSmall borderFull gameText gameTextAlign'; else newField.className = 'gameCellSmall borderWithoutTop gameText gameTextAlign'; newField.onclick = function() { this.DivClick('a'); } this.fields[fieldNumber] = newField; return newField; } GameField.prototype.DivClick = function(fieldNumber) { alert('Nummer: ' + fieldNumber); } Everything works perfectly, but when you click on one of the created divs, i end up with the following error message: Error: Object doesn't support this property or method. If i replace the onclick function with this, then it works: newField.onclick = function() { alert('Nummer: ' + fieldNumber); } How can i get the onclick event to fire my DivClick function instead?

  • Why can't I write just a try with no catch or finally?

    - by Camilo Martin
    Sometimes I do this and I've seen others doing it too: VB: Try DontWannaCatchIt() Catch End Try C#: try { DontWannaCatchIt(); } catch {} I know I should catch every important exception and do something about it, but sometimes it's not important to - or am I doing something wrong? Is this usage of the try block incorrect, and the requirement of at least one catch or finally block an indication of it?

  • Exception handling pattern

    - by treefrog
    It is a common pattern I see where the error codes associated with an exception are stored as Static final ints. when the exception is created to be thrown, it is constructed with one of these codes along with an error message. This results in the method that is going to catch it having to look at the code and then decide on a course of action. The alternative seems to be- declare a class for EVERY exception error case Is there a middle ground ? what is the recommended method ?

  • C# Performance on Errors

    - by pm_2
    It would appear that catching an error is slower that performing a check prior to the error (for example a TryParse). The related questions that prompt this observation are here and here. Can anyone tell me why this is so - why is it more costly to catch an error that to perform one or many checks of the data to prevent the error?

  • Methods in Customized View did not get invoke in AppDelegate, Why?

    - by NorthKyut
    I want the methods pauseGame in customized UIView - MyGameView get invoked when the phone is locked or interrupted. So I have a pauseGame method but it can't stop the timer when user lock screen (command+L). The lock screen did appear but the game still running at the background. So I added the testPause method to MyGameView and MyGameAppDelegate and and put a breakpoint to debug it. When screen locked it, the screen lock appeared and the code did stop at the breakpoint. But when I tried to step into the testPause method, it didn't take me to the method in MyGameView (it just passed it, not skipped) and no message was printed on terminal by NSLog. Why? What did I miss? // // MyGameAppDelegate.h // MyGame // #import <UIKit/UIKit.h> @class MyGameViewController; @class MyGameView; @interface MyGameAppDelegate : NSObject { UIWindow *window; MyGameViewController *viewController; MyGameView *view; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet MyGameViewController *viewController; @property (nonatomic, retain) IBOutlet MyGameView *view; @end // // MyGameAppDelegate.m // MyGame // #import "MyGameAppDelegate.h" #import "MyGameViewController.h" #import "MyGameView.h" @implementation MyGameAppDelegate @synthesize window; @synthesize viewController; @synthesize view; - (void)applicationWillResignActive:(UIApplication *)application { /* Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state. Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game. */ [view pauseGame]; [view testPause]; } @end // // MyGameView.h // MyGame @interface MyGameView : UIView { - (void)pauseGame; - (void)testPause; @end // // MyGameView.m // MyGame // #import "MyGameView.h" #import "AtlasSprite.h" #import "MyGameViewController.h" #import "SecondViewController.h" @implementation MyGameView - (void)pauseGame { [theTimer invalidate]; theTimer = nil; } - (void)testPause{ NSLog(@"TestPause"); } @end

  • Whether to check for null

    - by coffeeaddict
    I know that you should always check incoming params to a method for null. But what if I have this scenario with a try/catch referring to a local variable. Do I really need to check for null below? Because it's gonna catch it anyway if it's null and the next line of code tries to use the refundResponse variable: public string DoRefund(...) { try { ...... string refundTransactionID = string.Empty; ...... RefundTransactionResponseType refundResponse = transaction.DoRefund(...); if (refundResponse != null) refundTransactionID = refundResponse.RefundTransactionID; ..... } catch (Exception ex) { LogError(ex); return ex.ToString(); } }

  • Handling out of memory errors in iPhone

    - by hgpc
    I would like to handle out of memory errors in iPhone to execute logic with lesser memory requirements in case I run of of memory. In particular, I would like to do something very similar to the followin pseudo-code: UIImage* image; try { image = [UIImage imageNamed:@"high_quality_image.png"]; } catch (OutOfMemoryException e) { image = [UIImage imageNamed:@"low_quality_image.jpg"]; } First I attempt to load a high-quality image, and if I run out of memory while doing it, then I use a lower quality image. Would this be possible?

  • Google Anlytics event not firing

    - by yar1
    I am not getting and event data in GA. I installed Google Analytics Debugger Chrome extension and I see nothing happening (same goes when looking at Network panel in developer tools). I Googled it and read many (many) other answers and it looks like I'm doing things right. Page views, etc. are registering correctly... I have this code as the last thing before my closing tag: <script> (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){ (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o), m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m) })(window,document,'script','//www.google-analytics.com/analytics.js','ga'); ga('create', 'UA-MYREALCODE', 'mybna.net'); ga('send', 'pageview'); var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-MYREALCODE']); _gaq.push(['_trackPageview']); </script> My event handlers are done using jQuery, all inside an external js file, loaded before the closing tag. For example: $(function () { $('#show-less').click(function (e) { pbr.showHideMore(e); _gaq.push(['_trackEvent', 'ShowMore', 'Hide', 'top button']); }); }); Any ideas anyone?

  • PHP Postgres constraint violation - can I get the constraint name somehow?

    - by RnR
    We have a web application talking to a Postgres SQL database at work - I've set up many constraints on the server to keep data consistent but we have problems with reporting nicely what it is that prevents the user from entering his (invalid) data at a given moment. The only thing we can get is "Constraint violation" but that isn't very descriptive, from perl or directly from PGAdmin we get nice info as to which constraint caused the failure (the constraint's name) - is there a way to do the same in PHP? We're able to upgrade PHP or use a different db access module if it would help so I'm interested in knowing if it's possible to do using any way that you could safely recommend.

  • Handling a colon in an element ID in a CSS selector

    - by sblundy
    JSF is setting the ID of an input field to search_form:expression. I need to specify some styling on that element, but that colon looks like the beginning of a pseudo-element to the browser so it gets marked invalid and ignored. Is there anyway to escape the colon or something? input#search_form:expression { ///... }

  • Which of the two exceptions was called?

    - by Rob
    If I have a routine that can throw an ArgumentException in two places, something like... if (Var1 == null) { throw new ArgumentException ("Var1 is null, this cannot be!"); } if (Val2 == null) { throw new ArgumentException ("Var2 is null, this cannot be either!"); } What’s the best way of determining in my calling procedure which of the two exceptions was thrown? Or Am I doing this in the wrong fashion?

  • handling matrix data in python

    - by Ovisek
    I was trying to progressively subtract values of a 3D matrix. The matrix looks like: ATOM 1223 ZX SOD A 11 2.11 -1.33 12.33 ATOM 1224 ZY SOD A 11 -2.99 -2.92 20.22 ATOM 1225 XH HEL A 12 -3.67 9.55 21.54 ATOM 1226 SS ARG A 13 -6.55 -3.09 42.11 ... here the last three columns are representing values for axes x,y,z respectively. now I what I wanted to do is, take the values of x,y,z for 1st line and subtract with 2nd,3rd,4th line in a iterative way and print the values for each axes. I was using: for line in map(str.split,inp): x = line[-3] y = line[-2] z = line[-1] for separating the values, but how to do in iterative way. should I do it by using Counter.

  • try except block in Delphi

    - by Nik
    Do you guys know a way to trap log and re-raise exception in Delphi code. A simple example: procedure TForm3.Button1Click(Sender: TObject); begin try raise Exception.Create('Bum'); except on E: Exception do begin MyHandleException(E); end; end; end; procedure TForm3.MyHandleException(AException: Exception); begin ShowMessage(AException.Message); // raise AException; - this will access violate end; So I need to re-raise it in the except block but I was wondering is there a better way to write my own method to handle and (on specific conditions) to re-raise exceptions?

  • I set a global bug catcher in my application for unhandled exceptions and it is picking up all exceptions

    - by user1632018
    I am trying to figure out why this is happing. In my vb.net application I set a global handler in the ApplicationEvents.vb which I thought would only pick up any unhandled exceptions, although it is picking up every exception that happens in my application whether or not they are handled with try catch blocks. Here is my code in applicationevents Private Sub MyApplication_UnhandledException(ByVal _ sender As Object, ByVal e As _ Microsoft.VisualBasic.ApplicationServices.UnhandledExceptionEventArgs) _ Handles Me.UnhandledException e.ExitApplication = _ MessageBox.Show(e.Exception.Message & _ vbCrLf & "The application has encountered a bug, would you like to Continue?", "An Error has occured.", _ MessageBoxButtons.YesNo, _ MessageBoxIcon.Question) _ = DialogResult.No End Sub In the rest of my application I set normal try catch blocks like this: Try Catch ex as exception End Try Can anyone tell me why this is happening?

  • Handling multiple post-defined datasource connections based on user

    - by choudeshell
    How should I handle multiple user-connection defined datasource connection in my .NET application? To illustrate this better; the user provides three (3) pieces of information, username, password and data source name. This data source name is then looked-up in a central database telling that application which main database this user should connect to. My question is, in the DataAccess layer, should we only pass down enough information to uniquely identify that user, and query the central database each time in the DAL; or, should we provide another way to pass the datasource connection down to the DAL?
