  • Good C++ Debugging/IDE Environment for Linux?

    - by Brandon Pelfrey
    I have a friend who is trying to make the switch to Linux, but is hung up on the apparent lack of debugging/IDE environments for C++, especially as they relate to template programming. He has been using visual studio for years and is maybe a little spoiled by their awesome IDE. Does anyone have any good suggestions for an environment where he can, under Linux, develop and debug with all of the usual things (Breakpoints, line highlighting for compilation errors, step in/over/out/etc, etc) that he's accustomed to? Thanks!

  • Eclipse + AppEngine =? autocomplete

    - by Brandon Watson
    I was doing some beginner AppEngine dev on a Windows box and installed Eclipse for that. I liked the autocompletion I got with the objects and functions. I moved my dev environment over to my Macbook, and installed Eclipse Ganymede. I installed the AppEngine SDK and Eclipse plug in. However, when I am typing out code now, the autocomplete isn't functioning. Did I miss a step? UPDATE Just to add to this: the line: import cgi appears to give me what I need. When I type "cgi." I get all of the auto complete. However, the lines: from google.appengine.api import users from google.appengine.ext import webapp from google.appengine.ext.webapp.util import run_wsgi_app from google.appengine.ext import db don't give me any auto complete. If I type "users." there is no auto complete.

  • Attempting to load a 64-bit application, how this CPU is not compatible with 64-bit mode

    - by Brandon Michael Hunter
    I have a Dell Studio 540, 64 bit OS Windows Home Premium. My CPU is supports Intel's virtualization technology, but I don't know how to enabled it on my machine. I saw that you can do it via the bios, but I didn't see this option when going through my BIOS. Is there another way to enabled this feature? Please let me know. I'm trying to installed Windows Server 2008 via Vircutal PC 2007. Thank You,

  • How do I view executed queries within SQL Server Management Studio?

    - by Brandon
    I am new to SQL Server Management Studio and am wondering if there is a way to see what queries have been ran against a database. Surely there is a way to see these. In the Activity monitor, there is a "Recent Expensive Queries" but I'm guessing that isn't all of the queries since I'm not seeing the ones I have ran. I am running SQL Server 2008 v 10.0.1600.22.

  • Is it possible to write a database view that encompasses one-to-many relationships?

    - by Brandon Linton
    So I'm not necessarily saying this is even a good idea if it were possible, since the schema of the view would be extremely volatile, but is there any way to represent a has-many relationship in a single view? For example, let's say I have a customer that can have any number of addresses in the database. Is there any way to list out each column of each address with perhaps a number as a part of the alias (e.g., columns like Customer Id, Name, Address_Street_1, Address_Street_2, etc)? Thanks!

  • Hibernate Exception Fixed By Alt+Tab

    - by Lee Theobald
    Hi all, I've got a very curious problem in Hibernate that I would like some opinions on. In my code if I do the following: Go to page A Click a link on page A to be taken to page B Click on data item on page B Exception thrown I get an error telling me: failed to lazily initialize a collection of role: XYZ, no session or session was closed Fair enough. But when I do the same thing but add an alt+tab in the middle, everything is fine. E.g. Go to page A Click a link on page A to be taken to page B Hit ALt+Tab to switch to another application Hit ALt+Tab to switch back to the web browser Click on data item on page B Everything is fine. I'm a little confused as to how switching focus from my application makes it act as I want it to. Does anyone have any light to shine on the subject? I don't think it's a locking issue as even if I do the second set of steps quicker than the first, still no error. It's a Seam application using Hibernate 3.3.2.GA & 3.4.0.GA.

  • space in url; did browser got smarter or server?

    - by Xah Lee
    It looks like today you no longer to have to encode spaces by %20 in your html links or image links. For example, suppose you have this image at ?http://example.com/i/my house.jpg?. Notice the space there. In your html code, you can just do this: <img src="http://example.com/i/my house.jpg" alt="my house"> It work in all current version of browsers. Though, what i'm not sure is that whether the browser encodes it before requesting the url, or a particular server will do the right with with paths with space? (apache)

  • PHP Path issue running backticks/exec()

    - by Lee
    Hey all I'm trying to run a java jar file from the command line and within the the execution it gives a path. Withing this path their are spaces and this is causing the issue. ie $f = `java -jar /OCR/ocr.jar /Folder/Sub Folder/filetoocr.pdf /ocr/output.txt`; echo "<pre>$output</pre>"; If you can see the space in between the Sub Folder name causes the issue.

  • Segmentation fault on certain inputs and not others

    - by Brandon Schwandt
    Heres a function I wrote that has some debugging elements in it already. When i enter either a "y" or a "Y" as the input I get a segmentation fault during runtime. When I enter any other value the code runs. The seg fault kicks out after it scans and gives me the response but before the "scan worked" line is output. DOn't know why it would act like this only on these values. If anyone needs the function call I have that as well. query_user(char *response [10]) { printf("response after query call before clear=%s\n",response); strcpy(response,""); printf("response after clearing before scan=%s\n",response); printf("Enter another person into the line? y or n\n"); scanf("%s", response); printf("response after scan=%s\n",response); printf("scan worked"); } main() { char response [10]; strcpy(response,"y"); printf("response=%s\n",response); printf("When finished with program type \"done\" to exit\n"); while (strcmp(response,"done") != 0) { printf("response after while loop and before query call=%s\n",response); query_user(&response); } } output on error: response after query call before clear=y response after clearing before scan= Enter another person into the line? y or n y response after scan=y Segmentation Fault (core dumped) output on non-error: response after query call before clear=y response after clearing before scan= Enter another person into the line? y or n n response after scan=n scan worked Cycle number 0 (program continues to run outside this function)

  • MySQL Locking table from Stored FUNCTION

    - by Brandon
    I have a function in a MySQL Database that determines some sync parameters for a mobile device. The function determines the last date/time the user synchronized with the database. During my sync operation I call this server side function twice. As soon as I call it the second time - the entire Sync_Records table is locked. I cannot write to it from any other connection anywhere (note, after first call, the table is not locked). I changed the function to a Procedure - and all is fine - no locking after the second call. The entire sync operation (including both calls to the function/procedure) is within a transaction. This is an InnoDb table. The function/procedure simply does two select statements. They are storing results in local variables and then returning the date time variable. I don't understand why the tables are locked. Does anyone have any ideas?

  • Program is not displaying output correctly

    - by Dave Lee
    My program is suppose to display information from a text file. The text file is here http://pastebin.com/qB6nX2x4 I cant find the problem in my program. I think it has to deal with the looping but im not sure. My program runs correctly but only displays the first line of text. Any help would be appreciated. #include <iostream> #include <string> #include <cstdlib> #include <fstream> using namespace std; int buildArrays(int A[],int B[],int C[]) { int i=0,num; ifstream inFile; inFile.open("candycrush.txt"); if(inFile.fail()) { cout<<"The candycrush.txt input file did not open"<<endl; exit(-1); } while(inFile) { inFile>>num; A[i]=num; inFile>>num; B[i]=num; inFile>>num; C[i]=num; i++; } inFile.close(); return i; } void printArrays( string reportTitle, int levelsArray[], int scoresArray[], int starsArray[], int numberOfLevels ) { cout<<endl; cout<<reportTitle<<endl; cout<<"Levels\tScores\tStars"<<endl; cout<<"---------------------"<<endl; for(int i=0;i<numberOfLevels;i++) { cout<<levelsArray[i]<<"\t"<<scoresArray[i]<<"\t"; for(int j=0;j<starsArray[j];j++) { cout<<"*"; } cout<<endl; } } void sortArrays( int levelsArray[], int scoresArray[], int starsArray[], int numberOfLevels ) { for(int i=0;i<numberOfLevels;i++) { for(int j=0;j<numberOfLevels;j++) { if(levelsArray[i]<levelsArray[j]) { int temp1=levelsArray[i]; int temp2=scoresArray[i]; int temp3=starsArray[i]; levelsArray[i]=levelsArray[j]; scoresArray[i]=scoresArray[j]; starsArray[i]=starsArray[j]; levelsArray[j]=temp1; scoresArray[j]=temp2; starsArray[j]=temp3; } } } } int main() { const int MAX=400; int levelsArray[MAX]; int scoresArray[MAX]; int starsArray[MAX]; int numberOfLevels=buildArrays(levelsArray,scoresArray,starsArray); printArrays( "Candy Crush UNSORTED Report", levelsArray, scoresArray, starsArray, numberOfLevels ); sortArrays( levelsArray, scoresArray, starsArray, numberOfLevels); printArrays( "Candy Crush SORTED Report", levelsArray, scoresArray, starsArray, numberOfLevels ); system("pause"); }

  • Dash surrounding text

    - by Brandon Hansen
    Given the above dynamically generated text (meaning that I can't just use an image), I am trying to recreate the design using just html and css selectors. I would like to just use a single h4 with the containing text, but am open to other solutions. I would prefer to not use absolute positioning, but again, if that is the only way, then so be it. I have tried surrounding with span tags, but those are inline elements that don't have an inherent width. The h4 will be nested within a div, though not always of the same class or id. Any ideas or resources to get me started?

  • Why are controls within custom panel (C# winforms) disappearing in designer?

    - by Brandon
    I have been able to create a custom C# winforms control that is basically a panel with a fixed banner (header/footer). I want to base other user controls on this "banner panel". I've gotten past the problem with the designer here. I can successfully add controls to the inner content panel. Everything looks fine while designing. However, when I recompile, the controls I added to the content panel disappear. They are still there (in code) but aren't displayed in the designer. Is there any thing that I need to do to set the drawing order of the controls?

  • Generic that takes only numeric types (int double etc)?

    - by brandon
    In a program I'm working on, I need to write a function to take any numeric type (int, short, long etc) and shove it in to a byte array at a specific offset. There exists a Bitconverter.GetBytes() method that takes the numeric type and returns it as a byte array, and this method only takes numeric types. So far I have: private void AddToByteArray<T>(byte[] destination, int offset, T toAdd) where T : struct { Buffer.BlockCopy(BitConverter.GetBytes(toAdd), 0, destination, offset, sizeof(toAdd)); } So basically my goal is that, for example, a call to AddToByteArray(array, 3, (short)10) would take 10 and store it in the 4th slot of array. The explicit cast exists because I know exactly how many bytes I want it to take up. There are cases where I would want a number that is small enough to be a short to really take up 4 bytes. On the flip side, there are times when I want an int to be crunched down to just a single byte. I'm doing this to create a custom network packet, if that makes any ideas pop in to your heads. If the where clause of a generic supported something like "where T : int || long || etc" I would be ok. (And no need to explain why they don't support that, the reason is fairly obvious) Any help would be greatly appreciated! Edit: I realize that I could just do a bunch of overloads, one for each type I want to support... but I'm asking this question because I want to avoid precisely that :)

  • How do I bypass GUI in MFC app if command line options exist?

    - by Brandon
    I've got an existing simple MFC app that the user specifies the input file, output file, and then a "Process" button. I'd like to just add the capability so that the input/output files are command line parameters. But, if they exist, I don't want the GUI to show up. I just want the "Process" to execute. I see where I can get the command line parameters (m_lpCmdLine) but how can I bypass the displaying of the GUI? If I step into the app, it goes directly to winmain.cpp and displays the GUI without stepping into any of my code.

  • Whats the API Key for in Google Maps API V3?

    - by Brandon
    In the older version of the API, I'd have to insert the javascript into the page using something like this for just basic functionality to work: http://maps.google.com/maps?file=api&v=2&key=GoogleMapsAPIKey Where I had to configure the API key for each individual site. Looking at the documentation, it says to get a basic map working I just need this: http://maps.google.com/maps/api/js?sensor=true/false Where does the API key fit in? Do I need to worry about it if I just plan on using a basic map and marker and none of the more advanced functions?

  • RewriteRule to store thousands of files in subdirectories

    - by Brandon
    I have a website that will have millions of pages in a directory. I'd like to store those files on-disk in a bunch of subdirectories based on the first characters of the page name. For example http://mysite.com/hugedir/somefile.html would be stored in /var/www/html/hugedir/s/o/m/e/f/ile.html That is fairly trivial to do with a RewriteRule like so: RewriteRule ^hugedir/(.)(.)(.)(.)(.)(.*).html /hugedir/{$1}/{$2}/{$3}/{$4}/{$5}/$6.html RewriteRule ^hugedir/(.)(.)(.)(.)(.*).html /hugedir/{$1}/{$2}/{$3}/{$4}/{$5}.html RewriteRule ^hugedir/(.)(.)(.)(.*).html /hugedir/{$1}/{$2}/{$3}/{$4}.html RewriteRule ^hugedir/(.)(.)(.*).html /hugedir/{$1}/{$2}/{$3}.html RewriteRule ^hugedir/(.)(.*).html /hugedir/{$1}/{$2}.html RewriteRule ^hugedir/(.*).html /hugedir/{$1}.html However, the file name may contain hyphens or other non-standard characters and I'd really like to avoid having a directory named with a strange character. Ideally, I'd like to have a list of 'approved' characters and either eliminate or transform the unapproved characters to an underscore. Can anybody think of a way to do that? Or something else equivalent? Part of the requirement is that these be physical files on disk and it not be parsed with a scripting language.

  • Android 2.1 How to get Phone Numbers of contacts.

    - by Brandon Delany
    Hi, I am new to Android and have been working on an app that needs to get all of the user's contact's phone numbers. Apparently the code I have does not work with the 2.1 SDK. So far here is the code I am using: String[] projection = new String[] { Phone.NUMBER }; Cursor c = managedQuery( Phone.CONTENT_URI, projection, null, null, null ); int colIndex = -1; try { colIndex = c.getColumnIndexOrThrow( Phone.NUMBER ); } catch( Exception e ) { print( e.getMessage() ); } print( "Column Index = " + colIndex ); //count is equal to 3 for( int i = 0; i < count; i++ ){ try { print( c.getString( 2 ) ); //the 2 used to be colIndex } catch ( Exception e ) { print( e.getMessage() ); } } It seems that no matter what I pass into c.getString() it keeps telling me that I passed in -1. But I even hardcoded the 2, and it says the same thing. Any help would be much appreciated.

  • How do I get the Mac OS X 'quick look' feature to be more programmer-friendly?

    - by Lee
    There are numerous text files that are always included in common downloads such as rails plugins: LICENSE, ChangeLog, Rakefile, etc. I know these files are plain-text, but Mac OS X refuses to acknowledge this automatically. If I hit the spacebar in Finder to activate "quick look", the icon becomes huge but the contents of the file are not shown, presumably because they have no file extension. How do I stop this madness so I can quickly look at READMEs just by hitting the spacebar? I've already got a ton of text editors installed on my mac: this question is purely about efficiency and making simple files accessible as quickly as possible.

  • jQuery toggle menu dropdown

    - by Seong Lee
    I am working on a menu navigation that has parent horizontal bar as static and a vertical accordion child menu that interacts with the parent. I have them working fine except one part where I want to toggle show() and hide() child menu when clicked on the same parent menu item. I've looked at toggle() jQuery API but couldn't get it working properly. The following is only a script for parent part which I got rid of toggle() for now. $(function () { $('#mainMenu > ul > li > a').click(function () { $('#mainMenu li').removeClass('active'); $(this).closest('li').addClass('active'); if ($(this).text() == "1st click") { $('#subMenu > ul').siblings().hide(); $('#subMenu > ul:nth-child(1)').show(); } else if ($(this).text() == "2nd click") { $('#subMenu > ul').siblings().hide(); $('#subMenu > ul:nth-child(2)').show(); } }); }); The Full code that isolates the problem is available here

  • How can I (from a script) add something to the zsh command history?

    - by Brandon
    I'd like to be able to look through my command history and know the context from which I issued various commands--in other words, "what directory was I in?" There are various ways I could achieve this, but all of them (that I can think of) would require manipulating the zsh history to add (for instance) a commented line with the result of $(pwd). (I could create functions named cd & pushd & popd etc, or I could use zsh's preexec() function and maybe its periodic() function to add the comment line at most every X seconds, just before I issue a command, or perhaps there's some other way.) The problem is, I don't want to directly manipulate the history file and bypass the shell's history mechanism, but I can't figure out a way (with the fc command, for instance) to add something to the history without actually typing it on the command line. How could I do this?

  • Why are my margins still collapsing?

    - by Brandon Dorsey
    My code in this "Fiddle" shows that I have adjacent elements which vertical margins are collapsing on one another. I understand that due to the nature of vertical margins in css, the largest of the two is chosen, In my case the p tag. What I am having trouble with is trying to break the margins by using a 1px border or 1px padding. I've seen it work with other workarounds such as position:absolute or float method. I am not understanding why using 1px border or padding is not working properly to give me 15px of space.
