  • C# System.Diagnostics.Debugger.Debug() stopped working

    - by Andrew Miner
    I'm working on a program which uses the System.Diagnostics.Debugger.Break() method to allow the user to set a breakpoint from the command-line. This has worked fine for many weeks now. However, when I was working on fixing a unit test today, I tried to use the debug switch from the command-line, and it didn't work. Here's what I've tried: I've confirmed that the Debug() method is really being called (by putting a System.Console.WriteLine() after it) I've confirmed that the build is still in Debug I've done a clean build I've restarted Product Studio A quick Google search didn't reveal anything, and the API documentation for .Net doesn't mention anything about this function not performing correctly. So... any ideas?

  • Easy way to parse a url in C++ cross platform?

    - by Andrew Bucknell
    I need to parse a url to get the protocol host path and query in an application I am writing in c++. The application is intended to be cross platform. Im surprised I cant find anything that does this in boost or poco libraries. Is it somewhere obvious Im not looking? Any suggestions on appropriate open source libs? Or is this something I just have to do my self? Its not super complicated but it seems such a common task I am surprised there isnt a common solution.

  • Faking Fixed Position in IE6

    - by Andrew
    I have a site that utilizes a bottom fixed position masthead here: http://www.entheospartners.com/newsite/ This setup works great in all browsers except IE6, which doesn't support fixed positioning in the least, so here's what I've done: When an IE6 user comes to the page, I make the determination if scrolling is necessary using this bit of code: var windowHeight = $(window).height(); var totalHeight = windowHeight - 100; // where 100 is the sum of the top nav height + footer height var contentHeight; if($('#subpage-content-small').length) { // main content div for a three column layout contentHeight = $('#subpage-content-small').height(); }; if($('#subpage-content-wide').length) { // main content div for a two column layout contentHeight = $('#subpage-content-wide').height(); }; if(contentHeight > totalHeight) { $('#container-container').css({ 'overflow-y' : "scroll", 'height' : totalHeight }); }; ...which calculates everything correctly, puts the scrollbars where they need to be (flush right), and sets them to the appropriate height. The problem is that the scrollbars don't move the content. I can't say that I've ever seen anything quite like this before, so I'm hoping someone else on here has. Thanks in advance! PS - Obviously, this needs to be looked at in IE6 for troubleshooting, which I know will be as painful for you as it is for me.

  • Multiple Questions per page using Drupal Quiz

    - by Andrew
    I'm using the Drupal Quiz module, and have setup some basic quizzes and stuff like that. However some further customization is required, involving more than 1 question per page, and a multi-type answer in this type of format: Question 1: Describe 4 things you did last summer a) [ short answer space - text field ] b) "I wept" c) "My whole family died so I learned self reliance" d) "I got another xbox" Question 2: Describe 2 things you hate about yourself a) "My arms are way shorter than my legs" b) "I was born without human emotion" So I guess in two parts, how to show multiple questions per page, and then how to allow multiple text fields for answers. Oh and this quiz is not graded, it's like a self assessment. Thanks!

  • C++ Numerical truncation error

    - by Andrew
    Hello everyone, sorry if dumb but could not find an answer. #include <iostream> using namespace std; int main() { double a(0); double b(0.001); cout << a - 0.0 << endl; for (;a<1.0;a+=b); cout << a - 1.0 << endl; for (;a<10.0;a+=b); cout << a - 10.0 << endl; cout << a - 10.0-b << endl; return 0; } Output: 0 6.66134e-16 0.001 -1.03583e-13 Tried compiling it with MSVC9, MSVC10, Borland C++ 2010. All of them arrive in the end to the error of about 1e-13. Is it normal to have such a significant error accumulation over only a 1000, 10000 increments?

  • P/Invoke a Function Passed a StringBuilder

    - by andrew
    in a C# file i have a class Archiver { [DllImport("Archiver.dll")] public static extern void archive(string data, StringBuilder response); } string data is an input, and StringBuilder response is where the function writes something the archive function prototype (written in C) looks like this: void archive(char * dataChr, char * outChr); and it receives a string in dataChr, and then does a strcpy(outChr,"some big text"); from C# i call it something like this: string message = "some text here"; StringBuilder response = new StringBuilder(10000); Archiver.archive(message,response); this works, but the problem, as you might see is that i give a value to the StringBuilder size, but the archive function might give back a (way) larger text than the size i've given to my StringBuilder. any way to fix this?

  • remote_addr problem

    - by Andrew Kolvik
    I am using xampp on localhost and when I use _SERVER["REMOTE_ADDR"] it returns ::1 (also does this in phpinfo()). Why does it do this? I want it to return a normal ip address like 127.0.0.1. My operating system is windows vista.

  • how to determine if a character vector is a valid numeric or integer vector

    - by Andrew Barr
    I am trying to turn a nested list structure into a dataframe. The list looks similar to the following (it is serialized data from parsed JSON read in using the httr package). myList <- list(object1 = list(w=1, x=list(y=0.1, z="cat")), object2 = list(w=2, x=list(y=0.2, z="dog"))) unlist(myList) does a great job of recursively flattening the list, and I can then use lapply to flatten all the objects nicely. flatList <- lapply(myList, FUN= function(object) {return(as.data.frame(rbind(unlist(object))))}) And finally, I can button it up using plyr::rbind.fill myDF <- do.call(plyr::rbind.fill, flatList) str(myDF) #'data.frame': 2 obs. of 3 variables: #$ w : Factor w/ 2 levels "1","2": 1 2 #$ x.y: Factor w/ 2 levels "0.1","0.2": 1 2 #$ x.z: Factor w/ 2 levels "cat","dog": 1 2 The problem is that w and x.y are now being interpreted as character vectors, which by default get parsed as factors in the dataframe. I believe that unlist() is the culprit, but I can't figure out another way to recursively flatten the list structure. A workaround would be to post-process the dataframe, and assign data types then. What is the best way to determine if a vector is a valid numeric or integer vector?

  • How to handle concurrency control in dynamic data?

    - by Andrew
    I've been quite impressed with dynamic data and how easy and quick it is to get a simple site up and running. I'm planning on using it for a simple internal HR admin site for registering people's skills/degrees/etc. I've been watching the intro videos at www.asp.net/dynamicdata and one thing they never mention is how to handle concurrency control. It seems that DD does not handle it right out of the box (unless there is some setting I haven't seen) as I manually generated a change conflict exception and the app failed without any user friendly message. Anybody know if DD handles it out of the box? Or do you have to somehow build it into the site?

  • Monitor resolution changes look of website

    - by Andrew
    I have a website that looks fine in my resolution and even in the more common 1024 x 768. Yet, in someone else's browser in 1024 x 768, it's too wide and the website doesn't even center correctly. Is there a way to have a proper width layout that doesn't change when the resolution is changed?

  • Problems with .net and toolbar, menu & status bar rendermode (blue) and standard form (grey)

    - by Andrew White
    Hiya, I'm a bit of a newbie to .NET so please ignore my ignorance. If you look at the above image (a complete prototype, ignore black bits :)) you will see lovely menus, toolbars & statusbars all using windows XP render mode and in a funky blue. Look at the form, labels, checkboxes and other buttons and you see horrible old school windows grey. These components don't have a render mode. My question: is there any way to show everything in XP style or do I have to chose new components? Thx. A.

  • Incremement Page Hit Count in Django

    - by Andrew C
    I have a table with an IntegerField (hit_count), and when a page is visited (ie. http://site/page/3) I want record id 3 'hit_count' column in the database to increment by 1. The query should be like: update table set hit_count = hit_count + 1 where id=3 Can I do this with the standard Django Model conventions? Or should I just write the query by hand? I'm starting a new project, so I am trying to avoid hacks. We'll see how long this lasts! Thanks!

  • How do I get the server hostname from a mounted directory with cocoa/obj-c?

    - by Andrew
    Currently when I open a file with my program I can select files on a server by clicking on the server name in the sidebar in an NSOpenPanel and then selecting the file. No problem, this works fine for using the file as long as the shared directory is mounted. I get a path like "/Volumes/SHARENAME/filename.bla". My question is how do I get the server hostname of the computer it came from. For instance, if I clicked on the device with name SERVERNAME under "Shared" in the NSOpenPanel how do I get SERVERNAME from "/Volumes/SHARENAME/filename.bla". I have looked at quite a bit of documentation and have been unable to find a solution for this problem. Any help toward this will be greatly appreciated. Thank you.

    Hi, Weird question, but I have a dictionary created with StringComparer.OrdinalIgnoreCase, looks something like this AaA, 10 aAB, 20 AAC, 12 I then use myDictionary["AAA"] to find the value associated with the key, but what I also need to know is what the actual spelling of the key is in myDictionary, e.g. in this case I want it to return AaA. Any way to do this without a loop? Thx.

  • Doing a join across two databases with different collations on SQL Server and getting an error.

    - by Andrew G. Johnson
    I know, I know with what I wrote in the question I shouldn't be surprised. But my situation is slowly working on an inherited POS system and my predecessor apparently wasn't aware of JOINs so when I looked into one of the internal pages that loads for 60 seconds I see that it's a fairly quick, rewrite these 8 queries as one query with JOINs situation. Problem is that besides not knowing about JOINs he also seems to have had a fetish for multiple databases and surprise, surprise they use different collations. Fact of the matter is we use all "normal" latin characters that English speaking people would consider the entire alphabet and this whole thing will be out of use in a few months so a bandaid is all I need. Long story short is I need some kind of method to cast to a single collation so I can compare two fields from two databases. Exact error is: Cannot resolve the collation conflict between "SQL_Latin1_General_CP850_CI_AI" and "SQL_Latin1_General_CP1_CI_AS" in the equal to operation.

  • Can't correctly stream x264 video to mobile via RTSP

    - by Andrew
    Hello! I'm trying to stream video compressed with x264 and NeroAAC and hinted with MP4Box. When i'm playing it with VLC player streaming works fine, as expected. When i'm trying to open URL with my HTC Hero, it switches to player mode, then starts "loading video" animation, then after some time it shows "unable to connect to server". Sample movies provided with DSS streamed fine regardless bitrate. I tried few encoding options, but always the same result. I suspect nocabac and level=11 but it didn't changed nothing. Is there some more specific encoding options for such type? Thank You!

  • MySQL GROUP_CONCAT + IN() = missing data :-(

    - by Andrew Heath
    Example: Table: box boxID color 01 red 02 blue 03 green Table: boxHas boxID has 01 apple 01 pear 01 grapes 01 banana 02 lime 02 apple 02 pear 03 chihuahua 03 nachos 03 baby crocodile I want to query on the contents of each box, and return a table with each ID, color, and a column that concatenates the contents of each box, so I use: SELECT box.boxID, box.color, GROUP_CONCAT(DISTINCT boxHas.has SEPARATOR ", ") AS contents FROM box LEFT JOIN boxHas ON box.boxID=boxHas.boxID WHERE boxHas.has IN ('apple','pear') GROUP BY box.boxID ORDER BY box.boxID and I get the following table of results: boxID color contents 01 red apple, pear 02 blue apple, pear My question to you is: why isn't it listing ALL the has values in the contents column? Why is my WHERE statement also cropping my GROUP_CONCAT? The table I thought I was going to get is: boxID color contents 01 red apple, banana, grapes, pear 02 blue apple, lime, pear Although I want to limit my boxID results based upon the WHERE statement, I do not want to limit the contents field for valid boxes. :-/ Help?
