• Maven copy project output into other project resources

  - by Thomas

  There are two projects: 1) applet project that outputs jar file 2) web app project that should host the jar file. After (1) finished building, the applet jar file should be copied into the webapp folder of (2). The purpose is that (2) will host the applet (1) on the Internet. A lot of examples explain how to use another project as a library dependency. Other examples, show how to use ant plugin to copy files. I am unsure on how to properly set this up, so that 'mvn install' on the parent project will do the copying at the right time.

• WPF MVVM Pattern - References

  - by KroaX

  Hi everyone I wanted to know if some of you guys can post some articles, blog posts etc. that explain the MVVM Pattern in detail. There are not much explainations out there I think ( except Tutorials). I'm going to write my exam about WPF and also want to build in the MVVM Pattern. So I need some good references that are also digging a little deeper. I think I already have read a lot of texts about MVVM, but maybe you guys got some I didn't read yet. Would really appreciate if you would share your links to good and worth reading articles and explanations

• Dynamically creating a member ID card as pdf using PHP?

  - by aefxx

  I need to code a PHP script that would let me generate a pdf file which displays a member ID card (something like a credit card used to identify oneself) at a certain resolution. Let me explain: I do have the basic blueprint of the card in png file format. The script needs to drop in a member's name and birthday along with a serial. So far, no problem - there are plenty of good working PHP libraries out there. My problem is to ensure that the resulting pdf (the generated image of the card, to be precise) meets a certain resolution (preferably 300dpi), so that printing it would look right. Any ideas? EDIT I solved it using the TCPDF library which lets you scale images at a certain resolution. Get it here: http://www.tecnick.com/public/code/cp_dpage.php?aiocp_dp=tcpdf

  Been working my * off on this for a few days trying to keep updating it to make it most efficient with everything I learn... I'm quite proud of it so far considering I'm not actually the best coder lol most JS and PHP confuses the crap outa me unless I do it from scratch. So anyways here is the link. Tell me what you think. Suggestions would be amazing. I'd love to know what I screwed up as long as you explain in detail as to why and how to fix it. I really hate when people hand me a huge snippet and expect me to understand it -_- Thanks Shelby LINK http://opentech.durhamcollege.ca/~in...rittains/labs/

• How to write a virtual conditional breakpoint in java

  - by Phuong Nguyen de ManCity fan

  I'm sorry if the question title may mis-inform you, but I cannot find a proper word to explain that. If you ever working with .NET, you would know that there is Assert class that will automatically wake up and attach debugger if necessary and then have debugger (Visual Studio) pausing at the Assert command, given the Assert command failed. Given I'm running a java program and having debugger connected, then how can I have debugger to break on certain condition without manually setup a break point? I'm expecting something like that: void doSomeThing(String x){ if (x==null) breakDebuggerNow(); }

• Fixing warning from git

  - by japancheese

  I've been doing a workflow of making a git repository on a remote central repository, cloning that repo on my local dev machine, doing some work, and then pushing the changes back to the same repo on the remote server. However, and I believe this was after an update I did to git recently, after pushing up a change, I'm getting the following warning: Counting objects: 2724, done. Delta compression using up to 2 threads. Compressing objects: 100% (2666/2666), done. Writing objects: 100% (2723/2723), 5.90 MiB | 313 KiB/s, done. Total 2723 (delta 219), reused 0 (delta 0) warning: updating the currently checked out branch; this may cause confusion, as the index and working tree do not reflect changes that are now in HEAD. Can someone explain to me exactly what this warning means, and what I'm doing wrong in my workflow to not receive this warning?

• EndpointNotFoundException when working through tutorials in Learning WCF

  - by Nicholas

  I am working through the book Learning WCF and on the first tutorial lab HelloIndigo I am receiving the following error. Could not connect to http://localhost:8000/HelloIndigo/HelloIndigoService. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:8000. It appears in the Client project on the line string s = proxy.HelloIndigo(); EndpointAddress ep = new EndpointAddress("http://localhost:8000/HelloIndigo/HelloIndigoService"); IHelloIndigoService proxy = ChannelFactory<IHelloIndigoService>. CreateChannel(new BasicHttpBinding(), ep); string s = proxy.HelloIndigo(); Console.WriteLine(s); Console.WriteLine("Press <ENTER> to terminate Client"); Console.ReadLine(); I have intensively googled on this but I am none the wiser. Can anyone explain the issue and how to remedy?

• Can I set a property on an object that is only declared on the instance type, when I don't know the

  - by WilberBeast

  Let me explain. I have a List into which I am adding various ASP.NET controls. I then wish to loop through the list and set a CssClass, however not every Control supports the property CssClass. What I would like to do is test if the underlying instance type supports the CssClass property and set it, but I'm not sure how to do the conversion prior to setting the property since I don't know the type of each Control object. I know that I can use typeof or x.GetType(), but I'm not sure how to use these to convert the controls back to the instance type in order to test for and then set the property. Actually I seem to have solved this, so I thought that I would post the code here for others. foreach (Control c in controlList) { PropertyInfo pi = c.GetType().GetProperty("CssClass"); if (pi != null) pi.SetValue(c, "desired_css_class", null); } I hope that this helps someone else as I has taken me hours to research these 2 lines of code. Cheers Steve

• Why are alloc and init called separately in Objective-C?

  - by André Hoffmann

  Note: I'm relatively new to Objective-C and am coming from Java and PHP. Could someone explain to me why I always have to first allocate and then initialize an instance? Couldn't this be done in the init methods like this: + (MyClass*)init { MyClass *instance = [MyClass alloc]; [instance setFoo:@"bla"]; return instance; } + (MyClass*)initWithString:(NSString*)text { MyClass *instance = [MyClass init]; [instance setFoo:text]; return instance; } ... Is this just a relict from the old C days or is there something that I'm not seeing? I know this isn't a problem as I could as well always call alloc and init, but since it's a bit tedious I'd like to at least know why I'm doing it. I'm liking the expressiveness of the language so far, but this is something that I want to fully understand in order to think the Objective-C way. Thank you!

• How do i use RVM w/ Hudson CI server on Debian?

  - by JoshReedSchramm

  I'm trying to setup an automated "build" server for my rails projects using Hudson CI. SO far it's able to run specs and do metrics on the code but I have 2 different projects dependent on 2 different versions of ruby. So i'm trying to use RVM to run multiple copies of ruby then switch back and forth in a pre-build step. I found a couple posts like this one that try and explain how to make this work, but I'm not running a startup script for hudson, it starts on boot which is how it worked out of the box when i installed it via the debian instructions. The problem seems to be that even though hudson runs under the "hudson" account and that account has rvm installed (and working) when it tries to run a shell based prebuild step to call rvm switch 1.8.7 it fails with the error "rvm: command not found" Not sure what I'm doing wrong. Hudson is using SH as its shell but i also tried using bash. no luck. Has anyone gotten this working before in this setup?

• How is conversion of float/double to int handled in printf?

  - by Sandip

  Consider this program int main() { float f = 11.22; double d = 44.55; int i,j; i = f; //cast float to int j = d; //cast double to int printf("i = %d, j = %d, f = %d, d = %d", i,j,f,d); //This prints the following: // i = 11, j = 44, f = -536870912, d = 1076261027 return 0; } Can someone explain why the casting from double/float to int works correctly in the first case, and does not work when done in printf? This program was compiled on gcc-4.1.2 on 32-bit linux machine.

• Height of tableHeaderView seems to be 0

  - by gabac

  I tried to override the second tableHeaderView. But it seems that the height of it in the method heightForHeaderInSection seems to be 0. Can't explain it, do I have to put it in a iVar because in the viewForHeaderInSection I can set the view without any problems. - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { if(section == 0) return @"Adding a new list"; else return @"Other lists"; } - (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section { if(section == 0) { return tableView.tableHeaderView; } else { UIView *view = [[[UIView alloc] initWithFrame:CGRectMake(10, 10, 100, 50)] autorelease]; view.backgroundColor = [UIColor redColor]; return view; } } - (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section { if(section == 0) return tableView.tableHeaderView.frame.size.height; else return 30; }

• Why would I do an inner join on a non-distinct field?

  - by froadie

  I just came across a query that does an inner join on a non-distinct field. I've never seen this before and I'm a little confused about this usage. Something like: SELECT distinct all, my, stuff FROM myTable INNER JOIN myOtherTable ON myTable.nonDistinctField = myOtherTable.nonDistinctField (WHERE some filters here...) I'm not quite sure what my question is or how to phrase it, or why exactly this confuses me, but I was wondering if anyone could explain why someone would need to do an inner join on a non-distinct field and then select only distinct values...? Is there ever a legitimate use of an inner join on a non-distinct field? What would be the purpose? And if there's is a legitimate reason for such a query, can you give examples of where it would be used?

• .NET: What is the purpose of the ProhibitDtd property in XmlReaderSettings? Why is DTD a security i

  - by Cheeso

  The documentation says: When set to true, the XmlReader throws an XmlException when any DTD content is encountered. Do not enable DTD processing if you are concerned about Denial of Service issues or if you are dealing with untrusted sources. If you have DTD processing enabled, you can use the XmlSecureResolver to restrict the resources that the XmlReader can access. You can also design your application so that the XML processing is memory and time constrained. For example, configure time-out limits in your ASP.NET application. Can someone please explain the issue? Why would a reader application want to prohibit the retrieval of a DTD? Where is the denial-of-service issue, if it is a reading application? What is the "trust" issue that is mentioned? Thanks

• Git pre-receive hook

  - by Ralphz

  Hi When you enable pre-receive hook for git repository: It takes no arguments, but for each ref to be updated it receives on standard input a line of the format: < old-value SP < new-value SP < ref-name LF where < old-value is the old object name stored in the ref, < new-value is the new object name to be stored in the ref and is the full name of the ref. When creating a new ref, < old-value is 40 0. Does anyone can explain me how do I examine all the files that will be changed in the repository if i allow this commit? I'd like to run that files through some scripts to check syntax and so on. Thanks.

• Objectdatasource and Gridview : Sorting, paging, filtering

  - by Simon

  Hi there, Im using entity framework 1.0 and trying to feed out a Gridview with a objectdatasource that have access to my facade. The problem is, that it seems to be particulary difficult and haven't seen anything that realy do what i want it to do on the internet. For those who know, a gridview feeded with an objectdatasource, it can't sort automaticaly then you must do it manually. It's not that bad. Where it becomes a nightmare, its when we add paging and filter settings to a gridview's datasource. After many hours searching on the internet, i'm asking you, guys, if anyone knows a link that can explain me how to mix Pagging, Sorting and filtering for a gridview and an objectdatasource! Thanks in advance and sorry for my english.

• Difference between mutableArrayValueForKey and calling insertObject:inEmployeesAtIndex: directly

  - by jasonbogd

  I have a question regarding using KVO-compliant methods to insert/remove objects from an array. I'm working through Aaron Hillegass' Cocoa Programming for Mac OS X and I saw the following line of code (in the insertObject:inEmployeesAtIndex: method: [[undoManager prepareWithInvocationTarget:self] removeObjectFromEmployeesAtIndex:index]; Correct me if I'm wrong, but I always thought it was better to call mutableArrayValueForKey: and then removeObjectAtIndex:...so I tried changing the above line to this: [[undoManager prepareWithInvocationTarget:[self mutableArrayValueForKey:@"employees"]] removeObjectAtIndex:index]; And it didn't work. Can someone explain the difference and why the first line works but the second line doesn't?

• I cant really wrap my head around BOOLEAN logic when I use NOT together with AND and OR

  - by Bq

  Im trying to understand how boolean logic works when I use NOT. To give an example using awk I have a text file containing CORE PORT CORE PORT COREPORT CORE COREPORT And I would like to remove all COREPORT lines. The way I thought I would do it was with (NOT CORE) AND (NOT PORT) eg awk '/!CORE/&&/!PORT/{print}' But when I try it out Im actually supposed to use OR instead of AND awk '/!CORE/||/!PORT/{print}' I would be really glad if some one could explain where my thinking is wrong and super glad if it could be visualized with a venn diagram or something like the boolean machine at kathyschrock

StdOut : StdErr ).WriteLine(msg); When I have this code, I get the following exception at runtime: System.ObjectDisposedException: Cannot write to a closed TextWriter Can you explain why this happens? Can I avoid it and have more concise code like I wanted?

• Dotnetopenauth oAuth Service provider explanation

  - by ria

  I am a total newbie in the oAuth area and have set up DotNetOpenAuth to set up an oAuth Service provider. The sample provided in the DotNetOpenAuth download is quite confusing for me...maybe cos i am new to this stuff. There is one default page that creates a database and populates the database. Now I browse to the login.aspx and it asks me to put an openid, actually I want to use DNN (which implements DotNetOpenAuth) and i want to use those credentials on another site which will be the oAuth consumer. Can someone explain how to test the oAuth Service provider in the samples of DotNetOpenAuth?
