  • Python try/except: Showing the cause of the error after displaying my variables

    - by NealWalters
    I'm not even sure what the right words are to search for. I want to display parts of the error object in an except block (similar to the err object in VBScript, which has Err.Number and Err.Description). For example, I want to show the values of my variables, then show the exact error. Clearly, I am causing a divided-by-zero error below, but how can I print that fact? try: x = 0 y = 1 z = y / x z = z + 1 print "z=%d" % (z) except: print "Values at Exception: x=%d y=%d " % (x,y) print "The error was on line ..." print "The reason for the error was ..."

  • C++/MFC: Handling multiple CListCtrl's headers HDN_ITEMCLICK events

    - by raph.amiard
    I'm coding an MFC application in which i have a dialog box with multiple CListCtrls in report view. I want one of them to be sortable. So i handled the HDM_ITEMCLICK event, and everything works just fine .. Except that if i click on the headers of another CListCtrl, it does sort the OTHER CListCtrl, which does look kind of dumb. This is apparently due to the fact that headers have an ID of 0, which make the entry in the message map look like this : ON_NOTIFY(HDN_ITEMCLICK, 0, &Ccreationprogramme::OnHdnItemclickList5) But since all the headers have an id of zero, apparently every header of my dialog sends the message. Is there an easy way around this problem ?

  • Counting words in a collection using LINQ

    - by icemanind
    Guys, I have a StringCollection object with 5 words in them. 3 of them are duplicate words. I am trying to create a LINQ query that will count how many unique words are in the collection and output them to to the console. So, for example, if my StringCollection has 'House', 'Car,'House','Dog', 'Cat', then it should output like this: House -- 2 Car -- 1 Dog -- 1 Cat -- 1 any ideas on how to create a LINQ query to do this?

  • Missing features in Visual Studio?

    - by Sean Kearon

  • jquery get the index of a row?

    - by KnockKnockWhosThere
    I'm trying to write a function that will do something if the the row index is 0, and then something else if the row index is greater than 0. The zero part is working, but I can't figure out the syntax for rows that have an index greater than 0. For the tr[0] row, I'm doing this: if($("#mytable > tbody > tr ").index(0)) { ... I tried: if($("#mytable > tbody > tr ").index() > 0 ) { But, that didn't work?

    i have a repeater inside a dynamic control, i am trying to get the items of the repeater in a postback prior to databinding. this seems to work when i have a static repeater where the items are still intact, but when my repeater is inside a dynamic control and i try to get "repeater.Items", the count is always 0. is this normal behavior for repeaters when being placed inside a dynamic control?

  • Difference between BOOST_CHECK_CLOSE and BOOST_CHECK_CLOSE_FRACTION?

    - by Rhys Ulerich
    Can anyone describe the difference in behavior between BOOST_CHECK_CLOSE and BOOST_CHECK_CLOSE_FRACTION? The documentation implies the that both macros treat their third parameter identically, which makes me suspect the documentation is wrong. In particular, BOOST_CHECK_CLOSE_FRACTION gives me some odd looking results: error in "...": difference between *expected{0} and *actual{-1.7763568394002506e-16} exceeds 9.9999999999999995e-07 Is there a gotcha because I expect a zero result? I've not been successful at reading through the underlying macro declarations. Please note BOOST_CHECK_SMALL isn't appropriate for my use case (comparing two vectors after a linear algebra operation).

  • What is faster in MySQL? WHERE sub request = 0 or IN list

    - by Nicolas Manzini
    Hello I was wondering what is better in MySQL. I have a SELECT querry that exclude every entry associated to a banned userID currently I have a subquerry clause in the WHERE statement that goes like AND (SELECT COUNT(*) FROM TheBlackListTable WHERE userID = userList.ID AND blackListedID = :userID2 ) = 0 Which will accept every userID not present in the TheBlackListTable Would it be faster to retrieve first all Banned ID in a previous request and replace the previous clause by AND creatorID NOT IN listOfBannedID Thank you!

    Kind of hard to explain, but when I run something like this: fruits = ['apple', 'orange', 'banana', 'strawberry', 'kiwi'] for fruit in fruits: print fruit.capitalize() It gives me this, as expected: Apple Orange Banana Strawberry Kiwi How would I edit that code so that it would "count" the amount of times it's performing the for, and print this? 1 Apple 2 Orange 3 Banana 4 Strawberry 5 Kiwi

  • Sort/Group XML data with PHP?

    - by Volmar
    I'm trying to make a page using data from the discogs.com (XML)-API. i've been parsing it with simpleXML and it's working pretty well but there is some things i'm not sure how to do. Here is part of the XML: <releases> <release id="1468764" status="Accepted" type="Main"> <title>Versions</title> <format>12", EP</format> <label>Not On Label</label> <year>1999</year> </release> <release id="72246" status="Accepted" type="Main"> <title>The M.O.F Blend</title> <format>LP</format> <label>Blenda Records</label> <year>2002</year> </release> <release id="890064" status="Accepted" type="Main"> <title>The M.O.F Blend</title> <format>CD</format> <label>Blenda Records</label> <year>2002</year> </release> <release id="1563561" status="Accepted" type="TrackAppearance"> <title>Ännu En Gång Vol. 3</title> <trackinfo>Backtrack</trackinfo> <format>Cass, Comp, Mix</format> <label>Hemmalaget</label> <year>2001</year> </release> </releases> What i want to achieve is something similair to how discogs presents the releases: http://www.discogs.com/artist/Mics+Of+Fury where diferent versions of the same release are sorted together. (see. The M.O.F Blend in my link) This is done on discogs with having a master release that features the other releases. unfortunately this information isn't present in the API data, so i want to do the same thing by grouping the <release>-nodes with the same <title>-tags, or add a flag to the <releases> that don't have a unique <title>? any good ideas on the best way of doing this? i also like to know if it's possible to count the <release>-nodes (child of releases) that have the same type-attribute? like in this example count the releases with the type "Main"? maybe it's better to do this things with XMLReader or XPath?

  • Excel - check if row contains ANY value *more than once*

    - by user2536778
    I am doing data analysis and sometimes I need to check and to make sure each row in excel does not have any repeated value. I hope that there is a formula where each time if there's a repeated value in the same row, the value will be highlighted and it doesn't matter what value it is, as long as it's repeated in the same row. I try to search it everywhere but the closest I can find is below question & answer ( which couldn't apply to me as I need a formula that can highlight any value that's repeated and not only zero): I have rows which contain grades for students (numerical values), where the number 0 means they missed a class. I want the row to be highlighted in one color if they have "0" 3 or 4 times, and in another color if they have "0" 5 times or more. =COUNTIF(1:1,0)=5 Anyone can help me? Thanks in advance!

  • PHP regular expression

    such text: $text = ' href="http://yahoo.com" target="_blank"> link text </a> text... text... <br> text...'; // $text = ' text... <a href="http://yahoo.com" target="_blank"> link text </a> text... text... <br> text...'; and such regular expression: preg_match_all('/^(.*)(<.+>)(.*)(<\/.+>)(.*)$/',$text,$matches); what I want, - to check if text matches the regular expression. If yes, then $matches should contain parts of string above, if not (as I guess) it should contain four zero-length arrays. something is wrong, but I can't find, what actually is?

  • pushScene and popScene or replaceScene . which should we use and when ?

    - by srikanth rongali
    I am using push scene to get the next scene. But, I read that for each PushScene the scene is stored in stack. The memory usage is more. So, I am using the replaceScene in place of pushScene. But, with replace scene I am getting the memory-bad-access message in debugger. So, I want to popScene after using it, so that the retain count is zero. But, I am confused in using popScene. If I have a Scene1 and Scene2. I used the following to go in to Scene2. Now I need to remove Scene1 from stack. [[CCDirector sharedDirector] pushScene:Scene2]; Where should I write the popScene to popScene1. How to get the previous scene in current running scene ? Thank you/
