• Pointer Implementation Details in C

  - by Will Bickford

  I would like to know architectures which violate the assumptions I've listed below. Also I would like to know if any of the assumptions are false for all architectures (i.e. if any of them are just completely wrong). sizeof(int *) == sizeof(char *) == sizeof(void *) == sizeof(func_ptr *) The in-memory representation of all pointers for a given architecture is the same regardless of the data type pointed to. The in-memory representation of a pointer is the same as an integer of the same bit length as the architecture. Multiplication and division of pointer data types are only forbidden by the compiler. NOTE: Yes I know this is nonsensical. What I mean is - is there hardware support to forbid this incorrect usage? All pointer values can be casted to a single integer. In other words, what architectures still make use of segments and offsets? Incrementing a pointer is equivalent to adding sizeof(the pointed data type) to the memory address stored by the pointer. If p is an int32* then p+1 is equal to the memory address 4 bytes after p. I'm most used to pointers being used in a contiguous, virtual memory space. For that usage, I can generally get by thinking of them as addresses on a number line. See (http://stackoverflow.com/questions/1350471/pointer-comparison/1350488#1350488).

• Side by side madness - running binaries on different computer (with a twist)

  - by sbk

  Here's my configuration: Computer A - Windows 7, MS Visual Studio 2005 patched for Win7 compatibility (8.0.50727.867) Computer B - Windows XP SP2, MS Visual Studio 2005 installed (8.0.50727.42) My project has some external dependencies (prebuilt DLLs - either build on A or downloaded from the Internet), a couple of DLLs built from sources and one executable. I am mostly developing on A and all is fine there. At some point I try to build my project on computer B, copying the prebuilt DLLs to the output folder. Everything builds fine, but trying to start my application I get The application failed to initialize properly (0xc0150002).... The event log contains two of those: Dependent Assembly Microsoft.VC80.CRT could not be found and Last Error was The referenced assembly is not installed on your system. plus the slightly more amusing Generate Activation Context failed for some.dll. Reference error message: The operation completed successfully. At this point I'm trying my Google-Fu, but in vain - virtually all hits are about running binaries on machines without Visual Studio installed. In my case, however, the executables fail to run on the computer they are built. Next step was to try dependency walker and it baffled me even more - my DLLs built from sources on the same box cannot find MSVCR80.DLL and MSVCP80.DLL, however the executable seems to be alright in respect to those two DLLs i.e. when I open the executable with dependency walker it shows that the MSVC?80.DLLs can be found, but when I open one of my DLLs it says they cannot. That's where I am completely out of ideas what to do so I'm asking you, dear stackoverflow :) I admit I'm a bit blurry on the whole side-by-side thing, so general reading on the topic will also be appreciated.

• Smarty multiple random numbers list

  - by Heinrich

  Hey Stackoverflow-Folks, is there any smart way to post random numbers (e.g. 1-4) in a list by using the smarty tpl-engine? standart list sorted 1-5: <ul> <li>1</li> <li>2</li> <li>3</li> <li>4</li> <li>5</li> </ul> Here's my solution (PHP): <ul> {foreach from=randomNumbers} <li>{smarty.randomNumbers}</li> {/foreach} </ul> modified list sorted 1-5 (random): <ul> <li>3</li> <li>2</li> <li>5</li> <li>1</li> <li>4</li> </ul> I've really tested nearly everything, but I do only need a smart & small solution for this :-) Kind Regards, Heinrich

• Can I use POSIX signals in my Perl program to create event-driven programming?

  - by Shiftbit

  Is there any POSIX signals that I could utilize in my Perl program to create event-driven programming? Currently, I have multi-process program that is able to cross communicate but my parent thread is only able to listen to listen at one child at a time. foreach (@proc) { sysread(${$_}{'read'}, my $line, 100); #problem here chomp($line); print "Parent hears: $line\n"; } The problem is that the parent sits in a continual wait state until it receives it a signal from the first child before it can continue on. I am relying on 'pipe' for my intercommunication. My current solution is very similar to: http://stackoverflow.com/questions/2558098/how-can-i-use-pipe-to-facilitate-interprocess-communication-in-perl If possible I would like to rely on a $SIG{...} event or any non-CPAN solution. Update: As Jonathan Leffler mentioned, kill can be used to send a signal: kill USR1 = $$; # send myself a SIGUSR1 My solution will be to send a USR1 signal to my child process. This event tells the parent to listen to the particular child. child: kill USR1 => $parentPID if($customEvent); syswrite($parentPipe, $msg, $buffer); #select $parentPipe; print $parentPipe $msg; parent: $SIG{USR1} = { #get child pid? sysread($array[$pid]{'childPipe'}, $msg, $buffer); }; But how do I get my the source/child pid that signaled the parent? Have the child Identify itself in its message. What happens if two children signal USR1 at the same time?

• Destroy process-less console windows left by Visual Studio debug sessions

  - by jon hanson

  A known bug with security update KB978037 can occur with Visual Studio 2003 (and 2008) where sometimes if you restart a debugging session on a console app then the console window doesn't get closed even though the owner process no longer exists. The problem is discussed further here: http://stackoverflow.com/questions/2402875/visual-studio-debug-console-sometimes-stays-open-and-is-impossible-to-close These zombie windows then can not be closed via the Taskbar or via the TaskManager, and typically require a power off/on to get rid of them. Over the period of even a single day you can accumulate quite a few of them, which clog up your TaskBar and are generally annoying. I thought I would knock up a simple C++ Win32 utility to attempt to call DestroyWindow() on these windows by passing the windows handle as a cmd-line argument and converting it to a HWND. I'm converting the handle from a string by parsing it as a DWORD then casting the DWORD to a HWND. This appears to be working as if I call GetWindowInfo() on the handle it succeeds. However calling DestroyWindow() on the handle fails with error 5 (access denied), presumably because the caller process (i.e. my app) doesn't own the window in question. Any ideas as to how I might get rid of the zombie windows, either via the above approach or any other alternative short of rebooting? I'm in a corporate environment so installing/uninstalling updates/service-packs etc isn't an option.

• PySide Qt script doesn't launch from Spyder but works from shell

  - by Maxim Zaslavsky

  I have a weird bug in my project that uses PySide for its Qt GUI, and in response I'm trying to test with simpler code that sets up the environment. Here is the code I am testing with: http://stackoverflow.com/a/6906552/130164 When I launch that from my shell (python test.py), it works perfectly. However, when I run that script in Spyder, I get the following error: Traceback (most recent call last): File "/home/test/Desktop/test/test.py", line 31, in <module> app = QtGui.QApplication(sys.argv) RuntimeError: A QApplication instance already exists. If it helps, I also get the following warning: /usr/lib/pymodules/python2.6/matplotlib/__init__.py:835: UserWarning: This call to matplotlib.use() has no effect because the the backend has already been chosen; matplotlib.use() must be called *before* pylab, matplotlib.pyplot, or matplotlib.backends is imported for the first time. Why does that code work when launched from my shell but not from Spyder? Update: Mata answered that the problem happens because Spyder uses Qt, which makes sense. For now, I've set up execution in Spyder using the "Execute in an external system terminal" option, which doesn't cause errors but doesn't allow debugging, either. Does Spyder have any built-in workarounds to this?

• Regular expression either/or not matching everything

  - by dwatransit

  I'm trying to parse an HTTP GET request to determine if the url contains any of a number of file types. If it does, I want to capture the entire request. There is something I don't understand about ORing. The following regular expression only captures part of it, and only if .flv is the first int the list of ORd values. (I've obscured the urls with spaces because Stackoverflow limits hyperlinks) regex: GET.?(.flv)|(.mp4)|(.avi).? test text: GET http: // foo.server.com/download/0/37/3000016511/.flv?mt=video/xy match output: GET http: // foo.server.com/download/0/37/3000016511/.flv I don't understand why the .*? at the end of the regex isnt callowing it to capture the entire text. If I get rid of the ORing of file types, then it works. Here is the test code in case my explanation doesn't make sense: public static void main(String[] args) { // TODO Auto-generated method stub String sourcestring = "GET http: // foo.server.com/download/0/37/3000016511/.flv?mt=video/xy"; Pattern re = Pattern.compile("GET .?\.flv."); // this works //output: // [0][0] = GET http :// foo.server.com/download/0/37/3000016511/.flv?mt=video/xy // the match from the following ends with the ".flv", not the entire url. // also it only works if .flv is the first of the 3 ORd options //Pattern re = Pattern.compile("GET .?(\.flv)|(\.mp4)|(\.avi).?"); // output: //[0][0] = GET http: // foo.server.com/download/0/37/3000016511/.flv // [0][1] = .flv // [0][2] = null // [0][3] = null Matcher m = re.matcher(sourcestring); int mIdx = 0; while (m.find()){ for( int groupIdx = 0; groupIdx < m.groupCount()+1; groupIdx++ ){ System.out.println( "[" + mIdx + "][" + groupIdx + "] = " + m.group(groupIdx)); } mIdx++; } } }

• Jquery Show Fields depending on Select Menu value but on page load

  - by Tim

  Hello, This question refers to the question http://stackoverflow.com/questions/835259/jquery-show-hide-fields-depening-on-select-value <select id="viewSelector"> <option value="0">-- Select a View --</option> <option value="view1">view1</option> <option value="view2">view2</option> <option value="view3">view3</option> </select> <div id="view1"> <!-- content --> </div> <div id="view2a"> <!-- content --> </div> <div id="view2b"> <!-- content --> </div> <div id="view3"> <!-- content --> </div> $(document).ready(function() { $.viewMap = { '0' : $([]), 'view1' : $('#view1'), 'view2' : $('#view2a, #view2b'), 'view3' : $('#view3') }; $('#viewSelector').change(function() { // hide all $.each($.viewMap, function() { this.hide(); }); // show current $.viewMap[$(this).val()].show(); }); }); When I select the 2nd item in the menu it shows the corresponding field. The exception to this is when the on page load the select menu already has the 2nd menu item selected, the field does not show. As you may be able to tell, I am new to jquery and could definetly use some help with adjusting this code so that the selected item's field is shown on page load. Thanks, Tim

• Using Silverlight for Views in ASP.Net MVC - a bad idea?

  - by bplus

  I'm currently writing a small application for use internally at my office. I started out teaching myself some MVC (I've been a C# dev for 3 years). One of the main requirements is editable grids - I quickly realised that silverlight (i have zero silverlight experience) could be a big help in this. I've managed to create a proof of concept of getting MVC and silverlight to talk back an forth by combining these two techniques: Creating a Rest API using MVC MVC SilverLight I also got some help on stackoverflow: silverlight-grids-mvc-http-post Essentially all I'm doing is embedding a silver light object in a view. Serializing the Model data as JSON and passing it to silverlight(using intit params written into the response). The silverlight object can post data back to the controller as JSON. So far this seems like it could work quite well. However I am a bit concerned that I could be painting myself into a corner with this approach, as in I don't have much experience with either technology so I'm worried I'm going get hit with something further down the line that I won't be able to work around. Has anybody else tried doing this? Any advice would be much appreciated!

• Why does this data YYYY-MM-DD regex fail in Java?

  - by ProfessionalAmateur

  Hello StackOverFlow, My first question and Im excited... I've lurked since go-live and love the site, however I apologize for any newbie errors, formatting, etc... I'm attempting to validate the format of a string field that contains a date in Java. We will receive the date in a string, I will validate its format before parsing it into a real Date object. The format being passed in is in the YYYY-MM-DD format. However I'm stuck on one of my tests, if I pass in "1999-12-33" the test will fail (as it should with a day number 33) with this incomplete pattern: ((19|20)\\d{2})-([1-9]|0[1-9]|1[0-2])-([12][0-9]|3[01]) However as soon as I add the characters in bold below it passes the test (but should not) ((19|20)\\d{2})-([1-9]|0[1-9]|1[0-2])-(0[1-9]|[1-9]|[12][0-9]|3[01]) *additional note, I know I can change the 0[1-9]|[1-9] into 0?[1-9] but I wanted to break everything down to its most simple format to try and find why this isn't working. Here is the scrap test I've put together to run through all the different date scenarios: import java.util.regex.Matcher; import java.util.regex.Pattern; public class scrapTest { public scrapTest() { } public static void main(String[] args) { scrapTest a = new scrapTest(); boolean flag = a.verfiyDateFormat("1999-12-33"); } private boolean verfiyDateFormat(String dateStr){ Pattern datePattern = Pattern.compile("((19|20)\\d{2})-([1-9]|0[1-9]|1[0-2])-(0[1-9]|[1-9]|[12][0-9]|3[01])"); Matcher dateMatcher = datePattern.matcher(dateStr); if(!dateMatcher.find()){ System.out.println("Invalid date format!!! -> " + dateStr); return false; } System.out.println("Valid date format."); return true; } } Ive been programming for ~10 years but extremely new to Java, so please feel free to explain anything as elementary as you see fit.

• Creating search functionality with Laravel 4

  - by Mitch Glenn

  I am trying to create a way for users to search through all the products on a website. When they search for "burton snowboards", I only want the snowboards with the brand burton to appear in the results. But if they searched only "burton", then all products with the brand burton should appear. This is what I have attempted to write but isn't working for multiple reasons. Controller: public function search(){ $input = Input::all(); $v= Validator::make($input, Product::$rules); if($v->passes()) { $searchTerms = explode(' ', $input); $searchTermBits = array(); foreach ($searchTerms as $term) { $term = trim($term); if (!empty($term)){ $searchTermBits[] = "search LIKE '%$term%'"; } } $result = DB::table('products') ->select('*') ->whereRaw(". implode(' AND ', $searchTermBits) . ") ->get(); return View::make('layouts/search', compact('result')); } return Redirect::route('/'); } I am trying to recreate the first solution given for this stackoverflow.com problem The first problem I have identified is that i'm trying to explode the $input, but it's already an array. So i'm not sure how to go about fixing that. And the way I have written the ->whereRaw(". implode(' AND ', $searchTermBits) . "), i'm sure isn't correct. I'm not sure how to fix these problems though, any insights or solutions will be greatly appreciated.

• Best ways to copyright protect your work for example Myows

  - by Saif Bechan

  Recently I have read about Myows, they say its: "The universal copyright management and protection app for smart creatives" It is used to protect your application from copyrights and more. Do you think this will be a good idea for large application, or are there better ways to achieve such a thing. url: Myows Update Referencing: http://stackoverflow.com/questions/2618015/has-anyone-tried-myows-to-copyright-protect-your-work/2618628#2618628 Wow there is no better person to have answered this question like the creator himself. Currently I am working on a large web application which is in late testing phase. Because of the complexity of the app there are not many versions of it online so copyright will be a huge issue for me as much of the code is in JavaScript and is easy copyable. I was glad to see that there is some company out there that provide such services, and naturally I wanted to know if there were people using it. I did not know that this type of concept was so 'new'. There were some nice points made in the answer, and I think it will be a good service for people like me. In the next couple of weeks I will be looking further into the subject and start uploading my code and see how it will works out. I will leave this question up because I do want some more suggestions on this topic.

• SWT TabFolder: Weird Drawing Behaviour

  - by JesperGJensen

  Hello StackOverflow Experts Description I have an SWT Page with a TabFolder with a number of dynamically created TabItems. On each TabItem i crate a Composite and set the TabItem.setControl() to the Composite. I then use this Composite as the page on which i draw my items. I draw a set of Controls, including Textbox's and Labels. For the First, Default Tab, this works fine. No problems. Problem On tabs that is not the first tab i have the following problems: I am unable to visually alter then Edited/Enabled state of my Controls. I am unable to visually set the Text content of my elements My Controls look disabled and have a Greyed out look. But i am able to Select the content with my mouse and use CTRL+C to copy it out. So the text contet is there and they are Editable. Visually it is just not updated. Any comments are appeciated, Any requests for code, examples will be supplied and help Welcommed. Updates I tried added the suggest debug loop to the code, where i attempt to enable my Controls. This was the result: [main] INFO [dk.viking.controller.LayerController] - f038.stklok is now Editable [true] and enabled [true] [main] INFO [dk.viking.controller.LayerController] - true Text {} [main] INFO [dk.viking.controller.LayerController] - true Composite {} [main] INFO [dk.viking.controller.LayerController] - true TabFolder {} [main] INFO [dk.viking.controller.LayerController] - true Shell {Viking GUI}

• DOS Batch file to echo a specific line number

  - by Lee

  So for the second part of my current dilemma, I have a list of folders in "c:\file_list.txt". I need to be able to extract them (well, echo them with some mods) based on the line number because this batch script is being called by an iterative macro process. I'm passing the line number as a parameter. @echo off setlocal enabledelayedexpansion set /a counter=0 set /a %%a = "" for /f "usebackq delims=" %%a in (c:\file_list.txt) do (if "!counter!"=="%1" goto :printme & set /a counter+=1) :printme echo %%a which gives me an output of "%a". Doh! So, I've tried echoing !a! (result: "ECHO is off."); I've tried echoing %a (result: a) I figured the easy thing to do would be to modify the "head.bat" code found here: http://stackoverflow.com/questions/130116/dos-batch-commands-to-read-first-line-from-text-file except rather than echoing every line - I'd just echo the last line found. Not as simple as one might think. I've noticed that my counter is staying at zero for some reason; I'm wondering if the "set /a counter+=1" is doing what I think it's doing.

• When is someone else's code I use from the internet "mine"?

  - by robault

  I'm building a library from methods that I've found on the internet. Some are free to use or modify with no requirements, others say that if I leave a comment in the code it's okay to use, others say when I use the code I have to attribute the use of someone's code in my application (in the credits for my app I guess). What I've been doing is reorganizing classes, renaming methods, adding descriptions (code comments), renaming the parameters and names inside the methods to something meaningful, optimizing loops if applicable, changing return types, adding try/catch/throw blocks, adding parameter checks and cleaning up resources in the methods. For example; I didn't come up with the algorithm for blurring a Bitmap but I've taken the basic example of iterating through the pixels and turned it into a decent library method (applying the aforementioned modifications). I understand how to go about building it now myself but I didn't actually hit the keystrokes to make it and I couldn't have come up with it before learning from their example. What about code people get in answers on Stackoverflow or examples from Codeproject? At what point can I drop their requirements because at n% their code became mine? FWIW I intend on using the libraries to create products that I will sell.

• What is the performance penalty of XML data type in SQL Server when compared to NVARCHAR(MAX)?

  - by Piotr Owsiak

  I have a DB that is going to keep log entries. One of the columns in the log table contains serialized (to XML) objects and a guy on my team proposed to go with XML data type rather than NVARCHAR(MAX). This table will have logs kept "forever" (archiving some very old entries may be considered in the future). I'm a little worried about the CPU overhead, but I'm even more worried that DB can grow faster (FoxyBOA from the referenced question got 70% bigger DB when using XML). I have read this question http://stackoverflow.com/questions/514827/microsoft-sql-server-2005-2008-xml-vs-text-varchar-data-type and it gave me some ideas but I am particulairly interrested in clarification on whether the DB size increases or decreases. Can you please share your insight/experiences in that matter. BTW. I don't currently have any need to depend on XML features within SQL Server (there's nearly zero advantage to me in the specific case). Ocasionally log entries will be extracted, but I prefer to handle the XML using .NET (either by writing a small client or using a function defined in a .NET assembly).

• Could you please provide me with comments on a Java game of mine?

  - by Peter Perhác

  Hello there. I have marked this question as community wiki, so no rep points are thrown around. I made this game, Forest Defender, a proof-of-feasibility little project, which I would like to share with you and collect your constructive comments, first impressions, etc. It is a the first playable (and enjoyable) game I have released to the public, so I am, naturally, very eager to get some recognition by you, as my peers. I read in a StackOverflow blog, that One of the major reasons we created Stack Overflow to give every programmer a chance to be recognized by their peers. Recognized for their knowledge, their passion, [...] It comes in the form of a Java applet, I used an animation framework called PulpCore and I must say that it's been extremely enjoyable to work with it. I do recommend to people interested in Java game development.

• Where do I input a piece of code in Emacs?

  - by Vivi

  Hi there, I have just started using Emacs for the specific purpose of editing latex documents. I was attracted to Emacs because I want to be able to customize syntax highlighting even to the point of defining the colors of specific words. I am new to Emacs and not a programmer, so I having an extreme difficulty in doing what I want to do because most help I find assume too much knowledge for my level (it took me days just to be able to install emacs + auctex and change the first face color). I found something that I think will help me but I don't know how to do it. The post below is what I want to do, but what I am supposed to do with this code? Where should I insert it or where should I type it? I am using GNU Emacs in Windows. Thank you so much for you help :) M-x what-face will print the face found at the current point. And the code for that is: (defun what-face (pos) (interactive "d") (let ((face (or (get-char-property (point) 'read-face-name) (get-char-property (point) 'face)))) (if face (message "Face: %s" face) (message "No face at %d" pos)))) By the way, I found this in another post that can be found here: http://stackoverflow.com/questions/1242352/get-font-face-under-cursor-in-emacs

• Git as mercurial client? Why no git-hg?

  - by aapeli

  This is a question that's been bothering me for a while. I've done my homework and checked stackoverflow and found at least these two topics about my question: Git for Mercurial like git-svn and Git interoperability with a Mercurial repository I've done some serious googling to solve this issue, but so far with no luck. I've also read the Git Internals book, and the Mercurial Definitive Behind the Scenes to try to figure this out. I'm still a bit puzzled why I haven't been able to find any suitable git-hg type of a tool. From my perspective hg-svn is one of the main features, why I've chosen to use git over mercurial also at work. It allows me to use a workflow I like, and nobody else needs to bother, if they don't care. I just don't see the point in using the intermediate hg repo to convert back and forth, as suggested in one of the chains. So anyway, from what I've read hg and git seem very similar in conceptual design. There are differences under the hood, but none of those should prevent creating a git client for hg. As it seems to me, remote tracking branches and octopus merges make git even more powerful than hg is. So, the real question, is there any real reason why git-hg does not exist (or at least is very hard to find)? Is there some animosity from git users (and developers) towards their hg counterparts that has caused the lack of the git-hg tool? Do any of you have any plans to develop something like this, and go public with it? I could volunteer (although with very feeble C-skills) to participate to get this done. I just don't possess the full knowledge to start this up myself. Could this be the tool to end all DVCS wars for good?

• Visual Studio 2010 Professional - Problem Unit-Testing Web Services

  - by Ben

  Have created a very simple Web Service (asmx) in Visual Studio 2010 Professional, and am trying to use the auto-generated unit test cases. I get something that seems quite familiar on this site: The web site could not be configured correctly; getting ASP.NET process information failed. Requesting http://localhost:81/zfp/VSEnterpriseHelper.axd return an error: The remote server returned an error: (500) Internal Server Error. http://stackoverflow.com/questions/260432/500-error-running-visual-studio-asp-net-unit-test I have tried: 1. Running the tests on IIS rather than ASP.NET Development Server 2. Adding and then removing the XML fragment to my Web Service's .config file 3. Giving the MACHINE\ASPNET account Full control to the local folder My current questions: 1. Why am I being bothered with this instrumentation / code coverage DLL, when this doesn't seem to be something that ships with Visual Studio 2010 Professional? Is there any way I can turn it off? 2. I'm placing the node under in Web.config - is that the correct node? 3. Is it possible to bind to a web service without using the webby test attributes? I've seen other people advising making the Web Service as light-weight as possible. I'm trying to call it with jQuery / AJAX / JSON, so being able to debug the actual web service would be really helpful. Best wishes, Ben

  My input file is as below : HEADER {ABC|*|DEF {GHI 0 1 0} {{Points {}}}} {ABC|*|DEF {GHI 0 2 0} {{Points {}}}} {ABC|*|XYZ:abc:def {GHI 0 22 0} {{Points {{F1 1.1} {F2 1.2} {F3 1.3} {F4 1.4}}}}} {ABC|*|XYZ:ghi:jkl {JKL 0 372 0} {{Points {}}}} {ABC|*|XYZ:mno:pqr {GHI 0 34 0} {{Points {}}}} { ABC|*|XYZ:abc:pqr {GHI 0 68 0} {{Points {{F1 11.11} {F2 12.10} {F3 14.11} {F4 16.23}}}} } TRAILER I want to extract the file into an array as below : $array[0] = "{ABC|*|DEF {GHI 0 1 0} {{Points {}}}}" $array[1] = "{ABC|*|DEF {GHI 0 2 0} {{Points {}}}}" $array[2] = "{ABC|*|XYZ:abc:def {GHI 0 22 0} {{Points {{F1 1.1} {F2 1.2} {F3 1.3} {F4 1.4}}}}}" .. .. $array[5] = "{ ABC|*|XYZ:abc:pqr {GHI 0 68 0} {{Points {{F1 11.11} {F2 12.10} {F3 14.11} {F4 16.23}}}} }" Which means, I need to match the first opening curly brace with its closing curly brace and extract the string in between. I have checked the below link, but this doesnt apply to my question. http://stackoverflow.com/questions/413071/regex-to-get-string-between-curly-braces-i-want-whats-between-the-curly-braces I am trying but would really help if someone can assist me with their expertise ... Thanks Sri ...

• .Net System.Mail.Message adding multiple "To" addresses

  - by Matt Dawdy

  I just hit something I think is inconsistent, and wanted to see if I'm doing something wrong, if I'm an idiot, or... MailMessage msg = new MailMessage(); msg.To.Add("[email protected]"); msg.To.Add("[email protected]"); msg.To.Add("[email protected]"); msg.To.Add("[email protected]"); Really only sends this email to 1 person, the last one. To add multiples I have to do this: msg.To.Add("[email protected],[email protected],[email protected],[email protected]"); I don't get it. I thought I was adding multiple people to the "To" address collection, but what I was doing was replacing it. I think I just realized my error -- to add one item to the collection, use .To.Add(new MailAddress("[email protected]")) If you use just a string, it replaces everything it had in its list. Ugh. I'd consider this a rather large gotcha! Since I answered my own question, but I think this is of value to have in the stackoverflow archive, I'll still ask it. Maybe someone even has an idea of other traps that you can fall into.

• iPad width in viewport settings overflowing past device width

  - by user1327771

  I am at my wit's end here, and I beseech the fine folks here at stackoverflow for help. I am working on a design for a blog for a friend of mine, and I'm working in HTML5. I am trying to get the width of the page to span the width of an iPad. So, in my document head, I have the following: <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0"> Now, if you go to the index page, on an iPad, it looks just fine. The width of the page spans the width of the iPad in portrait mode, as I expect it to: http://www.alanreuterart.com/femmegamers/index.html It also looks fine on any individual blog posts as well. However, on the "about" and "join" pages, the width does not do this. It's actually overflowing past the length of the iPad to the right. View the following page on an iPad to see what I mean: http://www.alanreuterart.com/femmegamers/about.html I've tried everything. I cannot, for the life of me, figure out how to get it those two pages to correctly span the device width of the iPad. One important note, though: before anyone tells me to set my viewport width to 960, I cannot do that because the pages have media queries in them to convert to a mobile layout for the iPhone and other mobile phones. (I am not making a special unique layout for the iPad.) Can ANYONE help out here? Thanks in advance! —Me.

• NOT A DUPLICATE! VS2010 - How to automatically stop compile on first compile error

  - by Ben Robbins

  {rant}First I'd like to say that this IS NOT A DUPLICATE. I've asked this question previously but it got closed as a duplicate when it isn't. This question is SPECIFIC to VS 2010 and the answers to the so-called duplicate work in VS 2008 but not in VS 2010 (at least not for me or anyone I know). So before you go closing something as a duplicate how about you read the question carefully and try the answer for yourself and see if it actually works. Apologies for the rant but there is no obvious way to contact the SO police that closed the issue or get it reopened. {/rant} At work we have a C# solution with over 80 projects. In VS 2008 we use a macro to stop the compile as soon as a project in the solution fails to build (see this question for several options for VS 2005 & VS 2008: http://stackoverflow.com/questions/134796/how-to-automatically-stop-visual-c-build-at-first-compile-error). Is it possible to do the same in VS 2010? What we have found is that in VS 2010 the macros don't work (at least I couldn't get them to work) as it appears that the environment events don't fire in VS 2010. The default behaviour is to continue as far as possible and display a list of errors in the error window. I'm happy for it to stop either as soon as an error is encountered (file-level) or as soon as a project fails to build (project-level). Answers for VS 2010 only please. If the macros do work then a detailed explanation of how to configure them for VS 2010 would be appreciated. Thanks.

• Add Ellipsis to a Path in a WinForms Program without Win32 API call (revisited)

  - by casterle

  I was searching for a way to insert an ellipsis in a C# path, and found an answer here on stackoverflow: http://tinyurl.com/y6rmdfr Using the RTM versions of VS2010 and .Net 4.0, I was unable to get the suggested method to work. I searched the 'Net and found example code that uses the same method, but it failed in the same way. You can see the string I'm trying to shorten in my code below. After calling the MeasureText method, both the input string (OriginalName) and the output string (ellipsisedName) look like this: d:\abcd\efgh\ijkl\mnop\qrst\...\test.txt\0F\GHIJ\KLMN\OPQR\STIV\WXYZ\test.txt Two problems: 1) The resulting string is narfed (the path is truncated as expected, but is followed by what looks like a C-style terminating null and a chunk of the original path). 2) My original string is changed to be identical to the output string. Am I doing something wrong? namespace WindowsFormsApplication2 { public partial class Form1 : Form { public Form1() { InitializeComponent(); string OriginalPath = @"d:\abcd\efgh\ijkl\mnop\qrst\uvwx\yzAB\CDEF\GHIJ\KLMN\OPQR\STIV\WXYZ\test.txt"; string ellipsisedPath = OriginalPath; Size proposedSize = new Size(label1.Width, label1.Height); TextRenderer.MeasureText(ellipsisedPath, label1.Font, proposedSize, TextFormatFlags.ModifyString | TextFormatFlags.PathEllipsis); } } }
