• PyQt4: Why does Python crash on close when using QTreeWidgetItem?

  - by Rini

  I'm using Python 3.1.1 and PyQt4 (not sure how to get that version number?). Python is crashing whenever I exit my application. I've seen this before as a garbage collection issue, but this time I'm not sure how to correct the problem. This code crashes: import sys from PyQt4 import QtGui class MyWindow(QtGui.QMainWindow): def __init__(self, parent=None): QtGui.QMainWindow.__init__(self, parent) self.tree = QtGui.QTreeWidget(self) self.setCentralWidget(self.tree) QtGui.QTreeWidgetItem(self.tree) # This line is the problem self.show() app = QtGui.QApplication(sys.argv) mw = MyWindow() sys.exit(app.exec_()) If I remove the commented line, the code exits without a problem. If I remove the 'self.tree' parent from the initialization, the code exits without a problem. If I try to use self.tree.addTopLevelItem, the code crashes again. What could be the problem?

• Unable to catch exception from Activator.CreateInstance.

  - by Patrik Hägne

  OK, I admit it this code will just look weird to you, and that's because it is weird. This is just code to reproduce the behavior, not code I want to use. class Program { static void Main(string[] args) { try { Activator.CreateInstance(typeof(Func<int>), new object[] { new object(), IntPtr.Zero }); } catch { Console.WriteLine("This won't print!"); } Console.Write("Actually this will not print either!"); Console.ReadLine(); } } No matter what exception type I try to catch (the actual exception thrown is an ArgumentException as far as I can tell) the code inside the catch block will not execute. Actually execution will just stop at the Activator.CreateInstance-line.

• GEdit/Python execution plugin?

  - by Simon Woods

  Hi I'm just starting out learning python with GEdit plus various plugins as my IDE. Visual Studio/F# has a feature which permits the highlighting on a piece of text in the code window which then, on a keypress, gets executed in the F# console. Is there a similar facility/plugin which would enable this sort of behaviour for GEdit/Python? I do have various execution type plugins (Run In Python,Better Python Console) but they don't give me this particular behaviour - or at least I'm not sure how to configure them to give me this. I find it useful because in learning python, I have some test code I want to execute particular individual lines or small segments of code (rather then a complete file) to try and understand what they are doing (and the copy/paste can get a bit tiresome) ... or perhaps there is a better way to do code exploration? Many thx Simon

• Illegal instruction in Assembly

  - by Natasha

  I really do not understand why this simple code works fine in the first attempt but when putting it in a procedure an error shows: NTVDM CPU has encountered an illegal instruction CS:db22 IP:4de4 OP:f0 ff ff ff ff The first code segment works just fine: .model small .stack 100h .code start: mov ax,@data mov ds,ax mov es,ax MOV AH,02H ;sets cursor up MOV BH,00H MOV DH,02 MOV DL,00 INT 10H EXIT: MOV AH,4CH INT 21H END However This generates an error: .model small .stack 100h .code start: mov ax,@data mov ds,ax mov es,ax call set_cursor PROC set_cursor near MOV AH,02H ;sets cursor up MOV BH,00H MOV DH,02 MOV DL,00 INT 10H RET set_cursor ENDP EXIT: MOV AH,4CH INT 21H END Note: Nothing is wrong with windows config. I have tried many sample codes that work fine Thanks

• SVN Source control issues when merging changes

  - by HollyStyles

  I have seen where changes have been made on one code file by two developers code like this: x++ End up like this: x++ x++ where due to carriage returns being inserted/removed (I think) one line has become silently merged as two lines of the same code (no conflicts) Everything compiles but suddenly tests are failing and weird behaviour ensues. Should this be possible? How do I guard against it?

• Reading numeric Excel data as text using xlrd in Python

  - by Brian

  Hi guys, I am trying to read in an Excel file using xlrd, and I am wondering if there is a way to ignore the cell formatting used in Excel file, and just import all data as text? Here is the code I am using for far: import xlrd xls_file = 'xltest.xls' xls_workbook = xlrd.open_workbook(xls_file) xls_sheet = xls_workbook.sheet_by_index(0) raw_data = [['']*xls_sheet.ncols for _ in range(xls_sheet.nrows)] raw_str = '' feild_delim = ',' text_delim = '"' for rnum in range(xls_sheet.nrows): for cnum in range(xls_sheet.ncols): raw_data[rnum][cnum] = str(xls_sheet.cell(rnum,cnum).value) for rnum in range(len(raw_data)): for cnum in range(len(raw_data[rnum])): if (cnum == len(raw_data[rnum]) - 1): feild_delim = '\n' else: feild_delim = ',' raw_str += text_delim + raw_data[rnum][cnum] + text_delim + feild_delim final_csv = open('FINAL.csv', 'w') final_csv.write(raw_str) final_csv.close() This code is functional, but there are certain fields, such as a zip code, that are imported as numbers, so they have the decimal zero suffix. For example, is there is a zip code of '79854' in the Excel file, it will be imported as '79854.0'. I have tried finding a solution in this xlrd spec, but was unsuccessful.

• Adding an Object to Vector loses Reference using Java?

  - by thechiman

  I have a Vector that holds a number of objects. My code uses a loop to add objects to the Vector depending on certain conditions. My question is, when I add the object to the Vector, is the original object reference added to the vector or does the Vector make a new instance of the object and adds that? For example, in the following code: private Vector numbersToCalculate; StringBuffer temp = new StringBuffer(); while(currentBuffer.length() > i) { //Some other code numbersToCalculate.add(temp); temp.setLength(0); //resets the temp StringBuffer } What I'm doing is adding the "temp" StringBuffer to the numbersToCalculate Vector. Should I be creating a new StringBuffer within the loop and adding that or will this code work? Thanks for the help! Eric

• Documentation generator for Google Closure Javascript

  - by Julius Eckert

  I want to generate a HTML-Documentation for my Javascript code. The comments in my code are written in a format, the Google Closure Compiler can use to optimize my code. Example: /** * Class for handling timing events. * * @param {number=} opt_interval Number of ms between ticks (Default: 1ms). * @param {Object=} opt_timerObject An object that has setTimeout, setInterval, * clearTimeout and clearInterval (eg Window). * @constructor * @extends {goog.events.EventTarget} */ goog.Timer = function(opt_interval, opt_timerObject) { ... } I am looking for something like http://yardoc.org for Javascript. What tools can you recommend? Are there any specific tools for Google Closure code?

• Authenticated Referrals & Server-Side Auth Flow - What is the redirect_uri?

  - by Brian P. Hamachek

  From an authenticated referral (such as from a timeline story) to my website, I am trying to use the server-side authentication flow to obtain an access token for the referred user. I need to pass my app secret, the auth code, and the original redirect URI to the Facebook access token endpoint. Since I did not initiate the authentication request, how do I determine the original redirect_uri? The link from the Facebook timeline looks like: http://www.facebook.com/connect/uiserver.php?app_id=153644678059870&method=permissions.request&redirect_uri=http%3A%2F%2Fwww.wnmlive.com%2Fpost%2F141833948%3Ffb_action_ids%3D10100708033267487%26fb_action_types%3Dwnm-live%253Acomment%26fb_source%3Drecent_activity&response_type=code&display=page&auth_referral=1 So I figure that the redirect URI I need to pass is: http%3A%2F%2Fwww.wnmlive.com%2Fpost%2F141833948%3Ffb_action_ids%3D10100708033267487%26fb_action_types%3Dwnm-live%253Acomment%26fb_source%3Drecent_activity The URI that the user is ultimately redirected to is: http://www.wnmlive.com/post/141833948?fb_action_ids=10100708032119787&fb_action_types=wnm-live%3Apost&fb_source=recent_activity&code=AQALK-Mwb_Nwi4z7FWnFaL6tEXvNtVJiRKrgarG9X73sp22TJyk8v2GWKtuXuevJk4hPSRNnuNpEgZXLFdOS_k-pY-mE15DYytIa8Y7VdSw3VL-XYi-CR9BCqRQGq4uBJvSSdZayCp6MWzDMaNqWd5r8OhKVnOhg_yDlvfoLl21N2SMwkJaOfD5mlPnPb5A-Q4A#_=_ Is it safe to assume that I can just chop off everything starting with the "&code=" and use that as the redirect URI?

• Do you feel underappreciated or resent the geek/nerd stigma?

  - by dotnetdev

  At work we have a piece of A4 paper with the number of everyone in the office. The structure of this document is laid out in rectangles, by department. I work for the department that does all the technical stuff. That includes support—bear in mind that the support staff isn't educated in IT but just has experience in PC maintenance and providing support to a system we resell but don't have source code access to, project manager, team leader, a network administrator, a product manager, and me, a programmer. Anyway, on this paper, we are labelled as nerds and geeks. I did take a little offence to this, as much as it is light hearted (but annoying and old) humour. I have a vivid image that a geek is someone who doesn't go out but codes all day. I code all day at home and at work (when I have something to code...), but I keep balance by going out. I don't know why it is only people who work with computers that get such a stigma. No other profession really gets the same stigma—skilled, technical, or whatever. An account manager (and this is hardly a skilled job) says, "Perhaps [MY NAME HERE] could write some geeky code tomorrow to add this functionality to the website." It is funny how I get such an unfair stigma but I am so pivotal. In fact, if it wasn't for me, the company would have nothing to sell so the account managers would be redundant! I make systems, they get sold, and this is what pays the wages. It's funny how the account managers get a commission for how many systems they sell, or manage to make clients resubscribe to. Yet I built the thing in the first place! On top of that, my brother says all I do is type stuff on a keyboard all day. Surely if I did, I'd be typing at my normal typing speed of 100wpm+ as if I am writing a blog entry. Instead, I plan as I code along on the fly if commercial pressures and time prohibit proper planning. I never type as if I'm writing normal English. There is more to our jobs than just typing code. And my brother is a pipe fitter with no formal qualifications in his name. I could easily, and perhaps more justifiably, say he just manipulates a spanner or something. Does you feel underappreciated or that a geek/nerd stigma is undeserved or unfair?

• Replicating multicolumn lists from the Django admin CSS

  - by mfalcon

  Hi, I'm developing a Django project and I've to show a multicolumn list for the different objects of a table. I like the design of the django-admin for showing list-objects so I looked at the code to see how it works. As I am a CSS begginer the code seemed a bit difficult and extensive to comprehend. Is there a simplier way to make what I want or actually the CSS code of the django-admin is the path to follow?

• Tomcat upgradation

  - by cedar715

  We are planning to upgrade our Tomcat from 4.1.31. Our's is an Axis 1.4 application where we have our web services. Request you to suggest the latest stable version of Tomcat 5 or Tomcat 6 suitable for our application. And the things to consider while upgrading. Will the existing 1.4 Java code base works smoothly on Tomcat 5 or 6? And going further we may write the code in JDK 1.5 as well. So, having Java 1.4 code and Java 1.5 code together, will create any problems? Kindly suggest. Please share your upgradation experiences. Thank You :)

• What to do of exceptions when implementing java.lang.Iterator

  - by Vincent Robert

  The java.lang.Iterator interface has 3 methods: hasNext, next and remove. In order to implement a read-only iterator, you have to provide an implementation for 2 of those: hasNext and next. My problem is that these methods does not declare any exceptions. So if my code inside the iteration process declares exceptions, I must enclose my iteration code inside a try/catch block. My current policy has been to rethrow the exception enclosed in a RuntimeException. But this has issues because the checked exceptions are lost and the client code no longer can catch those exceptions explicitly. How can I work around this limitation in the Iterator class? Here is a sample code for clarity: class MyIterator implements Iterator { @Override public boolean hasNext() { try { return implementation.testForNext(); } catch ( SomethingBadException e ) { throw new RuntimeException(e); } } @Override public boolean next() { try { return implementation.getNext(); } catch ( SomethingBadException e ) { throw new RuntimeException(e); } } ... }

• Resizing image with Python with locked aspect ratio

  - by David Vinklar

  How should I resize an image with Python script so that it would automatically adjust the Height ratio to the Width used? I'm using the following code: def Do(Environment): # Resize App.Do( Environment, 'Resize', { 'AspectRatio': 1.33333, 'CurrentDimensionUnits': App.Constants.UnitsOfMeasure.Pixels, 'CurrentResolutionUnits': App.Constants.ResolutionUnits.PixelsPerIn, 'Height': 1440, 'MaintainAspectRatio': True, 'Resample': True, 'ResampleType': App.Constants.ResampleType.SmartSize, 'ResizeAllLayers': True, 'Resolution': 72, 'Width': 1920, }) Using this code works perfectly if the aspect ratio of an image is the same as the one defined in the code - i.e. 1.33333. But how should I make it work with images that do not have this ratio? For me, what is important is that the new Width is 1920; Height has to be able to adjust automatically. Any ideas which part of my code should be altered and how?

• Trying to run psexec to remote to server and recycle app pool

  - by James

  If I run this from my command prompt it works fine. psexec \ServerName cscript.exe iisapp.vbs /a AppName /r I'm trying to do the same thing with C# console app. I'm using the below code but most of the time the application hangs and doesn't complete, and the few times it does it throws an error code. Am I doing this wrong? Anyone know where I can look up the error or error code? static void RecycleAppPool(string sServer) { Console.Clear(); ProcessStartInfo p = new ProcessStartInfo("psexec.exe", "\\\\" + sServer + " cscript.exe iisapp.vbs /a <AppName> /r"); p.RedirectStandardInput = true; p.UseShellExecute = false; Process.Start(p); } When it completes with error, looks like this "cscript.exe exited with error code -2147024664"

• How do I mock memory allocation failures ?

  - by Andrei Ciobanu

  I want to extensively test some pieces of C code for memory leaks. On my machine I have 4 Gb of RAM, so it's very unlikely for a dynamic memory allocation to fail. Still I want to see the comportment of the code if memory allocation fails, and see if the recover mechanism is "strong" enough. What do you suggest ? How do I emulate an environment with lower memory specs ? How do i mock my tests ? EDIT: I want my tests to be code independent. I only have "access" to return values for different functions in the library I am testing. I am not supposed to write "test logic" inside the code I am testing.

  In Excel 2007 it is possible to scale a pictureLink object (created with the Camera Tool) using the following VBA code. With ActiveWorkbook.Sheets(sht).Pictures(name) .ShapeRange.ScaleWidth scaleValue, msoTrue .ShapeRange.ScaleHeight scaleValue, msoTrue .top = top .left = left End With This code places the picture correctly in 2010, but the scaleValue is ignored. The 2010 Excel documentation is patchy on this subject. The same code works fine in Excel 2007.

The code is in a format like this: QBYQC-Y??T3-W7G4R-QP4HG-2WQPT and they'll give you a hint such as two letters or a number and a letter. The solution to this is easy, brute-forcing it. However, I need the software that will make my browser repeatedly enter a new combination. What software can I use on Mac (and if not, Windows)?
