  • Python - removing double quotation marks " so that script runs

    - by andrew k
    I am using Python scripts to edit the table of many shape files. The following script runs fine, but if there are any " marks in the SIT_FULL_S field, the script errors and shuts down. gp.CalculateField_management(fc + "\\Parcels.shp","SIT_FULL_S", "!SIT_FULL_S!.lstrip('0')", "PYTHON") arcgisscripting.ExecuteError: ERROR 000539: Error running expression: "9030 W SR 2 HWY "A"".lstrip('0') <type 'exceptions.SyntaxError'>: invalid syntax (<string>, line 1) Failed to execute (CalculateField).

Can anyone help ?

  • Why does System.Threading.Timer callback successfully update UI?

    - by Geo P
    I have several System.Threading.Timers on my form application with callbacks that update the UI...successfully - i.e. without throwing errors. I had built these earlier, before I knew that UI should not be updated on any thread other than the UI thread. Now I am confused as to why it does not throw cross-thread exceptions when I am updating UI on these separate threading.timer threads? I will be changing these callbacks so that the UI updates are invoked on UI thread, but I am curious as to why this works. Edit: My application is a WinForms Application.

  • Ninject caching an injected DataContext? Lifecycle Management?

    - by awrigley
    I had a series of very bizarre errors being thrown in my repositories. Row not found or changed, 1 of 2 updates failed... Nothing made sense. It was as if my DataContext instance was being cached... Nothing made sense and I was considering a career move. I then noticed that the DataContext instance was passed in using dependency injection, using Ninject (this is the first time I have used DI...). I ripped out the Dependency Injection, and all went back to normal. Instantly. So dependency injection was the issue, but I still don't know why. I am speculating that Ninject was caching the injected DataContext. Is this correct? Is there a way of configuring the lifecycle management of injected parameters? If so, what would be the best configuration to use to have the DataContext behave like a normal DataContext, ie, no caching across requests?

  • Hibernate deletion issue

    - by muffytyrone
    I'm trying to write a Java app that imports a data file. The process is as follows Create Transaction Delete all rows from datatable Load data file into datatable Commit OR Rollback if any errors were encountered. The data loaded in step 3 is mostly the same as the data deleted in step3. The deletion is performed using the following DetachedCriteria criteria = DetachedCriteria.forClass(myObject.class); List<myObject> myObjects = hibernateTemplate.findByCriteria(criteria); hibernateTemplate.deleteAll(myObjects); When I then load the datafile, i get the following exception nested exception is org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: The whole process needs to take place in transaction. And I don't really want to have to compare the import file / data table and then perform an insert/update/delete to get them into sync. Any help would be appreciated.

  • Problems trying to format currency with Python (Django)

    - by h3
    I have the following code in Django: import locale locale.setlocale( locale.LC_ALL, '' ) def format_currency(i): return locale.currency(float(i), grouping=True) It work on some computers in dev mode, but as soon as I try to deploy it on production I get this error: Exception Type: TemplateSyntaxError Exception Value: Caught ValueError while rendering: Currency formatting is not possible using the 'C' locale. Exception Location: /usr/lib/python2.6/locale.py in currency, line 240 The weird thing is that I can do this on the production server and it will work without any errors: python manage.py shell >>> import locale >>> locale.setlocale( locale.LC_ALL, '' ) 'en_CA.UTF-8' >>> locale.currency(1, grouping=True) '$1.00' I .. don't get it.i

  • Can I detect unused extra parameters passed to javascript methods?

    - by Pablojim
    In Javascript I can call any method with more than the necessary amount of parameters and the extra parameters are silently ignored. e.g. letters = ['a','b','c'] //correct letters.indexOf('a') //This also works without error or warning letters.indexOf('a', "blah", "ignore me", 38) Are there ways to detect cases where this occurs? My motivation is that in my experience cases where this occurs are usually bugs. Identification of these by code analysis or at runtime would help track these errors down. These cases are especially prevalent where people are expecting alterations to base types which may not have occurred. Logging a warning where this happens e.g. Date.parse('02--12--2012', 'dd--MM--YYYY') Notes: To be clear I would like a solution that doesn't involve me sprinkling checks all over my code and other peoples' code.

  • How to make flyspell bypass some words by context?

    - by manu
    Hi, I use Emacs for writing most of my writings. I write using reStructuredText, and then transform them to LaTeX after some preprocessing since I write my citations á-la LaTeX. This is an excerpt of one of my texts (in Spanish): En \cite[pp.~XXVIII--XXIX]{Crnkovic2002} se brindan algunos riesgos que se pueden asumir con el desarrollo basado en componentes, los This text is processed by some custom scripts that deals with the \cite part so rst2latex can do its job. When I activate flyspell-mode it signals most of the citation keys as spelling errors. How can I tell flyspell not to spellcheck things within \cite commands. Furthermore, how can I combine rst-mode and flyspell, so that rst-mode would keep flyspell from spellchecking the following? reST comments reST code literal reST directive parameters and arguments reST raw directive contents Any ideas?

  • Android Source code download error

    - by user351850
    Hi all I have followed the instructions on the Android website on how to download the latest android source code files but it gives errors when i run this command: repo init -u git://android2.git.kernel.org/platform/manifest.git It gives the following error: Getting repo ... from git://android.git.kernel.org/tools/repo.git android.git.kernel.org[0: 199.6.1.176]: errno=Connection refused android.git.kernel.org[0: 130.239.17.12]: errno=Connection refused fatal: unable to connect a socket (Connection refused) On checking forums for its resolution, i was told that port 9418 was being blocked. I use Ubuntu 10.04 and ensured that the firewall wasnt blocking the port and also enabled the port and the above IP addresses. I also spoke to the networking peeps who ensured that no traffic from the internet is being blocked. I would be glad if i could get directions on how to proceed next. Many thanks as you respond.

  • Code won't exit foreach block

    - by Matt
    I've got the following C# code segment that takes a list, finds objects that are ready to update, then shoves them into a temp list, deletes from the main list, and then goes on its merry way. My issue is that the foreach block, which cycles through my main list, won't exit. TempLog.Clear(); //Ensure TempLog is empty foreach (CLogger ready in PlayerLog) { if (ready.UpdateReady == true) // Record is ready to be updated in database { TempLog.Add(ready); // Add record to templog PlayerLog.Remove(ready); // Remove from playerlog } } <---- Never reaches this point if (TempLog.Count > 0) // Just check that templog isn't empty { new Thread(Update).Start(); // Run update code } I've put heaps of debugging in, and I can watch PlayerLog start at 1, TempLog at 0, then it enters the foreach loop, picks up that the record UpdateReady flag is on, TempLog goes to 1, PlayerLog goes to 0, then it just stops.. No errors, just stops.. Thanks for the help :)

  • Is it kEatSpeed or kSpeedEat?

    - by bobobobo
    I have a bunch of related constants that are not identical. What's the better way to name them? way #1 kWalkSpeed kRunSpeed kEatSpeed kDrinkSpeed Or, way #2 kSpeedWalk kSpeedRun kSpeedEat kSpeedDrink If we evaluate these based on readability understandability not bug prone with subtle errors due to using wrong variable name I think way #1 wins readability, they tie for understandability, and way #2 wins for not bug prone. I'm not sure how often it happens to others, but when variable names like this get long, then its easy to write kSpeedEatingWhenInAHurry when you really meant kSpeedEatingWhenInHome, especially when using autocomplete. Any perspectives?

  • problems, custum wrap (class) around PDO, doesn't work

    - by Knarf
    DB::construct(); $STH = DB::prepare('INSERT INTO users (username, password, email, activationkey) VALUES (?, UNHEX(?), ?, ?)'); var_dump($STH); $result = $STH->execute(array('test', 'nils', '[email protected]', '227a038fe9c81515b514cb152188e95c')); echo "working? <br />"; if($result == false) echo 'noooo...'; It outputs and doesn't put anything in the database. Works with a similare code with DPO just without my DB class. But I doesn't get any errors. Anyone have an idea what the problem could be? object(PDOStatement)#2 (1) { ["queryString"]=> string(87) "INSERT INTO users (username, password, email, activationkey) VALUES (?, UNHEX(?), ?, ?)" } working? <br /> noooo...

  • Casting to global variable from LPVOID - C

    - by Jamie Keeling
    I am trying to cast data to a struct from a parameter passed into my method, I need the data to be passed to a global variable as it is needed elsewhere in my application. I have tried the following but I get errors saying that diceResult is an undeclared identifier Here is the code itself: //Structure to hold dice data typedef struct diceData { int dice1; int dice2; }; struct diceResult; DWORD WINAPI UnpackDiceData(LPVOID sentData) { //Unpack data struct diceData unpackedData = *((struct diceData*)sentData); diceResult.dice1 = unpackedData.dice1; diceResult.dice2 = unpackedData.dice2; } I don't understand why it won't recognise it being there when it's clearly global.

  • Django Inherited Field Access

    - by Rick
    As of the most current version, Django does not allow a subclass to have a variable with the same name as a variable in its superclass, if that variable is a Field instance. I need a subclass to modify this variable, which I call 'department'. Calling my classes super and sub, I need sub to modify the department variable it inherits from super. If I redeclare it, Django throws a field error. Of course, if I don't, department is not in scope for reassignment. If super has no department I get database errors. I get weird behaviour when I try rewriting init: def __init__(self): super(theSuperClass, self).__init__() TypeError: super(type, obj): obj must be an instance or subtype of type Anyone have any idea how to do this?

  • Can't run the ActionBarCompat sample

    - by David Miler
    I am having trouble compiling and running the ActionBarCompat sample of Android 16. I have API level 16 as the build target selected, which seems to build fine, but when I try to debug these errors pop up. Of course I could change the min API level in the manifest, but what would be the point of that? I have made no changes to the sample, so how come it is not working properly? Class requires API level 14 (current min is 3): android.view.ActionProvider SimpleMenuItem.java /ActionBarCompat/src/com/example/android/actionbarcompat line 129 Android Lint Problem Class requires API level 14 (current min is 3): android.view.ActionProvider SimpleMenuItem.java /ActionBarCompat/src/com/example/android/actionbarcompat line 134 Android Lint Problem Class requires API level 14 (current min is 3): android.view.MenuItem.OnActionExpandListener SimpleMenuItem.java /ActionBarCompat/src/com/example/android/actionbarcompat line 155 Android Lint Problem I am thoroughly confused, any help would be appreciated.

  • Unsigneds in order to prevent negative numbers

    - by Bruno Brant
    let's rope I can make this non-sujective Here's the thing: Sometimes, on fixed-typed languages, I restrict input on methods and functions to positive numbers by using the unsigned types, like unsigned int or unsigned double, etc. Most libraries, however, doesn't seem to think that way. Take C# string.Length. It's a integer, even though it can never be negative. Same goes for C/C++: sqrt input is an int or a double. I know there are reasons for this ... for example your argument might be read from a file and (no idea why) you may prefer to send the value directly to the function and check for errors latter (or use a try-catch block). So, I'm assuming that libraries are way better designed than my own code. So what are the reasons against using unsigned numbers to represent positive numbers? It's because of overflow when we cast then back to signed types?

  • casting between sibling classes, AS3

    - by felix-gasca
    I have two classes, derivedClassA and derivedClassB which both extend parentClass I'm declaring var o:parentClass and then, depending on what's going on, I want to cast o as either being of type derivedClassA or derivedClassB. Essentially, this: var o:parentClass ... if(shouldUseA) o = new derivedClassA(); else o = new derivedClassB(); o.doSomething(); But it's not working, I'm getting all sorts of errors. Isn't this how class inheritance works? I feel like I'm missing something really fundamental, but I can't figure out what. Am I supposed to be using interfaces instead? Is there another way of doing what I want?

  • Python If Statement Defaults to an elif

    - by Brad Carvalho
    Not sure why my code is defaulting to this elif. But it's never getting to the else statement. Even going as far as throwing index out of bound errors in the last elif. Please disregard my non use of regex. It wasn't allowed for this homework assignment. The problem is the last elif before the else statement. Cheers, Brad if item == '': print ("%s\n" % item).rstrip('\n') elif item.startswith('MOVE') and not item.startswith('MOVEI'): print 'Found MOVE' elif item.startswith('MOVEI'): print 'Found MOVEI' elif item.startswith('BGT'): print 'Found BGT' elif item.startswith('ADD'): print 'Found ADD' elif item.startswith('INC'): print 'Found INC' elif item.startswith('SUB'): print 'Found SUB' elif item.startswith('DEC'): print 'Found DEC' elif item.startswith('MUL'): print 'Found MUL' elif item.startswith('DIV'): print 'Found DIV' elif item.startswith('BEQ'): print 'Found BEQ' elif item.startswith('BLT'): print 'Found BLT' elif item.startswith('BR'): print 'Found BR' elif item.startswith('END'): print 'Found END' elif item.find(':') and item[(item.find(':') -1)].isalpha(): print 'Mya have found a label' else: print 'Not sure what I found'

  • Codeigniter Template library, add_js() method

    - by Karl
    using This Template Library when i try and use the add_js() function it errors out. I add the regions $_scripts to the template header file but when i load the page it says undefined variable _scripts. any thoughts? changed <?= $_scripts ?> to <?= (isset($_scripts)) ? $_scripts : “”; ?> and obviously i lose the error but the js file still isnt loading. I did an echo at each step though the add_js() method and the output is correct. I also did an output of $this-js and they both had the corret output. So it gets through the get_js method fine and sets the class variable fine but i dont get anything added to the actual page.

  • Generate "Finder.h" for a SIMBL plugin

    - by user1204395
    I'm trying to create a SIMBL plugin for Finder to add icon overlay over some files. I have this code: @implementation NSObject (FAIconOverlay) - (void)FAIconOverlay_TIconAndTextCell_drawIconWithFrame:(struct CGRect)arg1 { [self FAIconOverlay_TIconAndTextCell_drawIconWithFrame:arg1]; if (![self respondsToSelector:@selector(node)]) { return; } NSLog(@"%@", [[[NSClassFromString(@"FINode") nodeWithFENode:[(TNodeIconAndNameCell *)self node]] fullPath] lastPathComponent]); // Draw the icon overlay } - (void)FAIconOverlay_TDesktopIcon_drawIconInContext:(struct CGContext *)arg1 { [self FAIconOverlay_TDesktopIcon_drawIconInContext:arg1]; } @end I can draw the icon overlay but, when I try to get the path of the file I get a "Use of undeclared identifier TNodeIconAndNameCell". Looking this link < How to Write OS X Finder plugin I see that is neccessary to generate a Finder.h file... My question is: How to generate this file?? I tried running "class-dump -H Finder.app" but I get too more compiling errors Thank you very much!

  • mootools 1.1.1 scrollto element with class name ... anything like jquery?

    - by dtour
    I get the impression mootools will do this, but in a roundabout way. I am working with livevalidation script. What I want to achieve is when the from runs and errors are generated then the page will scroll to the first error found. This will be outputted as: <span class=" LV_validation_message LV_invalid">Can't be empty!</span> with jquery I could do the following: $.scrollTo($('span.LV_invalid:1')); I get the feeling in mootools I have to first find the position of the first span with class LV_invalid then pass this to the scrollTo function or is there a much simpler solution?

  • Adding nodes to a global linked-list

    - by Zack
    I am attempting to construct my first linked list, and having read a basic introduction, have done the following. Firstly, declare a linked list node as: struct errorNode { uint8 error; struct errorNode* next; }; Secondly, define the first node globally as: struct errorNode errorList = {0, NULL}; This has been done to allow each of the libraries that make up my current project to insert errors into a common list. The function to do this is: void errorListWrite(uint8 error) { struct errorNode* newNode = malloc(sizeof(struct errorNode)); newNode->error = error; newNode->next = &errorList; errorList = *newNode; } Whilst this compiles without error, it does not function as expected. I thnk the problem is with the last two statements of the list write function, but I am unsure. A hint as to what I am doing wrong would be most appreciated.

  • Trick to getting initWithNibFile to be invoked?

    - by PhazeZero
    I've implemented a View Controller, and I'm trying to do some very basic initialization in initWithNibFile...which I understand to be the designated initializer for View Controller objects. I've tried to put breakpoints on the code, and have put very simple NSLog statements into it as well. Regardless...I'm not seeing it be executed (and the object i'm attempting to alloc/init inside the function is also not being allocated - so I'm about 99% sure I'm not hitting the code. Is there something I need to do elsewhere to cause this method to be invoked? I'm getting a clean build, no warnings or errors. And the app successfully loads up the View, and I can invoke a ButtonClick method I've coded and connected to this same View Controller. Any suggestions would be appreciated. TC
