Linker, Libraries & Directories Information

- by m00st

I've finished both my C++ 1/2 classes and we did not cover anything on Linking to libraries or adding additional libraries to C++ code. I've been having a hay-day trying to figure this out; I've been unable to find basic information linking to objects. Initially I thought the problem was the IDE (Netbeans; and Code::Blocks). However I've been unable to get wxWidgets and GTKMM setup. Can someone point me in the right direction on the terminology and basic information about #including files and linking files in a Cpp application? Basically I want/need to know everything in regards to this process. The difference between .dll, .lib, .o, .lib.a, .dll.a. The difference between a .h and a "library" (.dll, .lib correct?) I understand I need to read the compiler documentation I am using; however all compilers (that I know of) use linker and headers; I need to learn this information. Please point me in the right direction! :] So far on my quest I've found out: Linker links libraries already compiled to your project. .a files are static libraries (.lib in windows) .dll in windows is a shared library (.so in *nix) Thanks

JSF Templating without RAD

- by Jeffrey Knight

I have a set of jsp's based off a jtpl template. The template (jtpl file) looks like this: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <%-- tpl:metadata --%> <%-- jsf:codeBehind language="java" location="/JavaSource/pagecode/my.java" --%> <%-- /jsf:codeBehind --%> <%-- /tpl:metadata --%> <%@taglib uri="http://www.ibm.com/jsf/html_extended" prefix="hx"%> <%@taglib uri="http://java.sun.com/jsf/html" prefix="h"%> <HTML> <%@taglib uri="http://java.sun.com/jsf/core" prefix="f"%> <%@page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <f:view> <HEAD> ... Without using RAD, how can I change the jtpl (template) and regenerate jsp? I'm looking for a command line solution. Related question: is the jsp intended to be rendered from the template design-time in the IDE, or runtime on the server?

How do you fix issues with the debugger for the Android plug-in for Eclipse not attaching?

- by user279112

I have been trying to program something for the Android mobile phone, using Eclipse and the Android plug-in for that IDE, and my debugger used to attach just fine. But then it has suddenly started having consistent issues attaching. I just get that message about how the process is waiting for the debugger attach, and then it just won't. What determines whether the attachment glitches so seems to have something to do with what the code is that I'm trying to debug, as it seems to be drastically more of an issue with some versions of my code than with others (on the same app). How do I fix this? Now before you answer, please understand that I have researched this issue already. I have found a couple of solutions that have worked with other people, but which do not work for me. One of which is setting the debuggable property in the main manifest file as true, and the other is going into Dev Tools and into some settings menu, and from there selecting the process and essentially saying to the fake phone, "Debug this process". Neither has really worked. Any other ideas? And just in case...I've run into one blasted technical issue like this after another trying to program for that stupid phone. And I'm not the only one who's having these issues; when I go online to research these issues, it is always very easy for me to find many people who have the same issues, and who are having to use the shottiest, sloppiest, most "ghetto" solutions to work around these issues. I know that many people have created good applications for that phone, but I don't see how I'm supposed to do that when the SDK and the plug-in just don't work half the time. Does anybody know how I may put all this trash behind me, once and for all? Thanks for your answers to either question!

Cant run application (C#) through cmd

- by user301639

Hey, I cant execute application through cmd, when the application trying to read the argument which was sent to it (text file), it fails... when i'm truing to execute it through the IDE (vs2008), it works ok... that's what i did in the main method : static void Main(string[] args) { int choice = 0; if (args.Length == 0) choice = 1; else choice = 2; switch(choice) { case 1: { string[] text = Directory.GetFiles("allText"); Console.WriteLine(DateTime.Now.ToString()); foreach (string fileName in text) { string substring = fileName.Substring(8); ReadData_Logic rd_l = new ReadData_Logic(substring); rd_l.runThreadsAndDecrypt(); rd_l.printKey(substring.Substring(0, fileName.Length - 15).Insert(0, "encryptedKey\\") + "_result.txt"); } Console.WriteLine(DateTime.Now.ToString()); } break; case 2: { Console.WriteLine(DateTime.Now.ToString()); string fileName = args[0]; Console.WriteLine(fileName); **<--- for debug, here i do see the correct file name** ReadData_Logic rd_l = new ReadData_Logic(fileName); rd_l.runThreadsAndDecrypt(); rd_l.printKey(fileName + "_result.txt"); Console.WriteLine(DateTime.Now.ToString()); } break; } } what wrong with the code ? thanks

Extension methods for encapsulation and reusability

- by tzaman

In C++ programming, it's generally considered good practice to "prefer non-member non-friend functions" instead of instance methods. This has been recommended by Scott Meyers in this classic Dr. Dobbs article, and repeated by Herb Sutter and Andrei Alexandrescu in C++ Coding Standards (item 44); the general argument being that if a function can do its job solely by relying on the public interface exposed by the class, it actually increases encapsulation to have it be external. While this confuses the "packaging" of the class to some extent, the benefits are generally considered worth it. Now, ever since I've started programming in C#, I've had a feeling that here is the ultimate expression of the concept that they're trying to achieve with "non-member, non-friend functions that are part of a class interface". C# adds two crucial components to the mix - the first being interfaces, and the second extension methods: Interfaces allow a class to formally specify their public contract, the methods and properties that they're exposing to the world. Any other class can choose to implement the same interface and fulfill that same contract. Extension methods can be defined on an interface, providing any functionality that can be implemented via the interface to all implementers automatically. And best of all, because of the "instance syntax" sugar and IDE support, they can be called the same way as any other instance method, eliminating the cognitive overhead! So you get the encapsulation benefits of "non-member, non-friend" functions with the convenience of members. Seems like the best of both worlds to me; the .NET library itself providing a shining example in LINQ. However, everywhere I look I see people warning against extension method overuse; even the MSDN page itself states: In general, we recommend that you implement extension methods sparingly and only when you have to. So what's the verdict? Are extension methods the acme of encapsulation and code reuse, or am I just deluding myself?

NetBeans parameter fill after code completion

- by byte

This is a particularly annoying problem I'm having, and I can't be the only one to have issue with it. In NetBeans, when you type part of a method, then hit CTRL-SPACE, it displays the code-completion popup, whereupon you can hit tab to finish out the word. This is great, and pretty much how all IDE's operate. Example: Thread.sl < CTRL-SPACE Thread.sleep Yay! Problem is that in this context, once you type in a paren, it auto-fills the parameters for the method with their default names, and inserts a closing paren (regardless of whether you have disabled the option to automatically close them on the preferences page for code completion). This behavior is NOT present if you had manually typed out the full name. How is this helpful to anyone? You've got to type over it your actual variable that you will be passing, and NetBeans gives you no option to prevent the closing paren on code-completion. Does anyone have a way to solve this issue, without having to dive into the netbeans source and build it just for this minor of an issue?

Send HTTPService Request in flex 3 with '-' in the URl Paramerters to get Google Feeds

- by Goysar

I am developing application in flex 3 which interacts with the Google feeds to produce my results. The URL to which i want to send request is something like this http://books.google.com/books/feeds/volumes?q=football+-soccer&start-index=11&max-results=10 Now i can send and receive results with q parameter, but in the next two parameters has a '-' (start-index and max-results). I am using HTTPService to send the requeset like this. SearchService.url = "http://books.google.com/books/feeds/volumes"; SearchService.method = "GET"; SearchService.contentType = "application/x-www-form-urlencoded" Here SearchService is the HTTPService var params:Object = new Object(); params.q = searchText; params.start-index = 11; params.max-results = 100; service.SearchService.send(params); Now my flex IDE throws me a error stating 'Cannot assign a non-reference value'. Only if i send the request with this parameters, i could put pagination in my application. So how can i send HTTPService request with '-' in the URL parameters?

Passing Multiple values Through Query String?

- by Googler

Hi all, I tried to pass more than one value through Query String from page1.aspx to page2.aspx. This is my Query string in the Grid View <a href="javascript:void(0);" onclick='javascript:window.open("Update.aspx?Regno= <%#Eval ("ID") %>'+ ","'&Fn=<%#Eval ("FIRSTNAME") %>' +", "'&Ln=<%#Eval ("LASTNAME") %>'")';> Edit</a> On My Page2.aspx, my code behind on PageLoad is: if (Page.IsPostBack) return; string id = Request.QueryString["ID"]; string Firstname = Request.QueryString["FIRSTNAME"]; string LastName = Request.QueryString["LASTNAME"]; My Visual Studio IDE shows a syntax error on this query string. I dont know the exact way to pass multiple values through Query String. How to make it work? Can anyone pls help me on this.. Which is the right syntax to pass multiple query string?

how could application installations/configurations be easier in linux? [closed]

- by ajsie

although you can do anything in linux it tends to require a lot of tweaking in config files and reading a lot of manuals/tutorials before you can have it running in your way. i know that it gets a lot easier by time, and the apt-get installations with ubuntu/debian is heading the right way. but how can linux be more userfriendly for us in the future? i thought that if more is automated like an IDE environment, eg. typing svn will give us all the commands and description about each command when you move between commands with your keyboard. that would be great. but that's just one example. another is the navigation in the terminal between folders. now you have to type a lot just to jump from/to different folders. would be great with some more automatization here too. i know that these extra features will slow down the server, but its 2010 now, and these features are not that heavy for the cpu, but makes it more userfriendly and encourage maintainance of a server, not frighten u off. what do you think about this? should/could we have more user friendly linux environment in servers, something that has annoyed you a lot? a lot of things are done in the unix way, but maybe we should reinvent the wheel in some areas, cause apparently, its so...repeatingly today and difficult to do easy tasks. it should be easier i think..

Visual Studio macro to navigate to T4MVC link

- by shannon

I use T4MVC and I'm happy with it and want to keep it - it keeps down run time defects. Unfortunately, it makes it harder to navigate to views and content (a.k.a. Views and Links in T4MVC) though. Even using Resharper, I can't navigate to the referenced item: T4MVC and Resharper Navigation Can I get a hand building a macro to do this? Never having built a VS IDE macro before, I don't have a grasp on how to get at some things, like the internal results of the "Go To Definition" process, if that's even possible. If you aren't familiar with T4MVC, here's generally what the macro might do to help: Given the token: Links.Content.Scripts.jQuery_js in the file MyView.cshtml, '(F12) Go To Definition'. This behaves properly. Having arrived at the the related assignment: public readonly string jQuery_js = "~/Content/Scripts/jQuery.js"; in a file generated by T4MVC (which is very nice, thank you David, but we really don't ever need to see), capture the string assigned and close the file. Navigate in Solution Explorer to the PhysicalPath represented by the captured string. This process would also work for views/layouts/master-pages/partials, etc. If you provide a macro or link to a macro to do this, or have another solution, wonderful. Otherwise, hints on how to do step 3 simply in a VS macro would be especially appreciated and receive upvote from me. I'd post the macro back here as an answer when done. Thanks!

Mixing JSP/HTML any new features or suggestions

- by Maglebolia

Hi all, I have a Web-Application, which is mainly JSP (file extension) and is including some HTML. It seems to me that the "general" way is "old" and not always well red by some IDE like Eclipse: Is there no other way to include jsp expression with "<% ... %". There is no need for a framework to resolve this, since we only have like 60 pages. I run through examples and see that we can seperate the code with blockquotes "< script < /script ". I'm really wondering which is the better method for understanding and easier reading of the code. Any formatting, syntax coloring, plugin or new code style suggestions would help. Here an example <%} %> <%if(condition) { %> <tr> <td class="label"><%=method()%></td> <td class="text"><%=method()%></td> </tr> <%} %> <tr>

Eclipse - Import existing mult-rep CVS project folder

- by iQ

Hey guys, Wondering if anyone can help me out with eclipse in terms of importing an existing CVS managed project. I am currently trying to shift my work on to the eclipse IDE. Some details about my project and environment below. I'm working in Linux Ubuntu, the project folder is located on a mounted shared network drive, I have installed the "Eclipse CVS Client" plug-in for my version of eclipse (helios). I've tried many ways for eclipse to use my existing folder as a project and recognize the CVS data in the CVS folders. I have done the following options: Created a new project, selected existing source, located my project folder and clicked OK to finish creating. In the end the CVS files weren't automatically read. Did the same as above and after project creation I wen to the option "project menu-team-share project", it asks me to choose a repository and doesn't automatically find the CVS information in the subfolders. If your wondering I have set-up both repositories in my eclipse and can browse the repositories through the CVS browser. My project directory layout is like this: +-Project Folder (no CVS folder at this level) +---Repo A folder +-----CVS meta-info folder is INSIDE, along with all checked out files from Repo A + +---Repo B folder +-----CVS meta-info folder is INSIDE, along with all checked out files from Repo B + +-(couple of random files, not in CVS) Thanks for the help

visual studio macro - copy a definition or declaration from/to .h to/from .cpp

- by Michael

Is it possible to do a macro that copies a definition of a function to a declaration, and also the opposite? For instance class Foo { Foo(int aParameter, int aDefaultParameter = 0); int someMethod(char aCharacter) const; }; from the .h file would be: Foo::Foo(int aParameter, int aDefaultParameter){ // } int Foo::someMethod(char aCharacter) const { return 0; } in the .cpp file. The opposite wouldn't work with the default value, but it would still be cool if it copied the declaration into the class in the header file. Also if it could return a default value as in someMethod (based on the return value from the declaration). Personally I tried to do macrocoding some year ago (I think it was around 2005) but the tutorials and documentation of macros was thin (or I hadn't searched enough). I ended up going through the examples that they had in the IDE but gave up when I figured it would take too long to learn. I would however like to give it a try again. So if there are anyone with knowledge of good tutorials or documentation that aims at Visual Studio .Net (and maybe also covers the above problem) I would probably accept that as an answer as well :)

Consulting a Prolog Source Code from within a VS2008 Solution File

- by Joshua Green

I have a Prolog file (Hanoi.pl) containing the code for solving the Hanoi Towers puzzle: hanoi( N ):- move( N, left, middle, right ). move( 0, _, _, _ ):- !. move( N, A, B, C ):- M is N-1, move( M, A, C, B ), inform( A, B ), move( M, C, B, A ). inform( X, Y ):- write( 'move a disk from ' ), write( X ), write( ' to ' ), writeln( Y ). I also have a C++ file written in VS2008 IDE: #include <iostream> #include <string> #include <stdio.h> #include <stdlib.h> using namespace std; #include "SWI-cpp.h" #include "SWI-Prolog.h" predicate_t phanoi; term_t t0; int main(int argc, char** argv) { long n = 5; int rval; if ( !PL_initialise(1, argv) ) PL_halt(1); PL_put_integer( t0, n ); phanoi = PL_predicate( "hanoi", 1, NULL ); rval = PL_call_predicate( NULL, PL_Q_NORMAL, phanoi, t0 ); system( "PAUSE" ); } How can I consult my Prolog source code (Hanoi.pl) from within my C++ code? Not from the Command Prompt - from the code, something like include or consult or compile? It is located in the same folder as my cpp file. Thanks,

String Length Evaluating Incorrectly

- by Justin R.

My coworker and I are debugging an issue in a WCF service he's working on where a string's length isn't being evaluated correctly. He is running this method to unit test a method in his WCF service: // Unit test method public void RemoveAppGroupTest() { string addGroup = "TestGroup"; string status = string.Empty; string message = string.Empty; appActiveDirectoryServicesClient.RemoveAppGroup("AOD", addGroup, ref status, ref message); } // Inside the WCF service [OperationBehavior(Impersonation = ImpersonationOption.Required)] public void RemoveAppGroup(string AppName, string GroupName, ref string Status, ref string Message) { string accessOnDemandDomain = "MyDomain"; RemoveAppGroupFromDomain(AppName, accessOnDemandDomain, GroupName, ref Status, ref Message); } public AppActiveDirectoryDomain(string AppName, string DomainName) { if (string.IsNullOrEmpty(AppName)) { throw new ArgumentNullException("AppName", "You must specify an application name"); } } We tried to step into the .NET source code to see what value string.IsNullOrEmpty was receiving, but the IDE printed this message when we attempted to evaluate the variable: 'Cannot obtain value of local or argument 'value' as it is not available at this instruction pointer, possibly because it has been optimized away.' (None of the projects involved have optimizations enabled). So, we decided to try explicitly setting the value of the variable inside the method itself, immediately before the length check -- but that didn't help. // Lets try this again. public AppActiveDirectoryDomain(string AppName, string DomainName) { // Explicitly set the value for testing purposes. AppName = "AOD"; if (AppName == null) { throw new ArgumentNullException("AppName", "You must specify an application name"); } if (AppName.Length == 0) { // This exception gets thrown, even though it obviously isn't a zero length string. throw new ArgumentNullException("AppName", "You must specify an application name"); } } We're really pulling our hair out on this one. Has anyone else experienced behavior like this? Any tips on debugging it?

Vim step-by-step: How do you line up arbitrary text by arbitrary delimiter?

- by dreftymac

Background: There are a lot of great tutorials and "tricks" pages for Vim, but one thing that is very difficult is to find specific instructions on how to do some arbitrary thing that one can easily do in one's own familiar text editor IDE. Therefore I am asking for step by step instructions on how you I would do something in Vim that I already know how to do in other text editors. I like Vim and the great built-in help and numerous on-line tutorials, but sometimes a human has to break down and ask another human. Question: Suppose I have the following code in my file, how can I use Vim to get from BEFORE, to AFTER? BEFORE: Lorem ipsum dolor | sit amet, consectetur | adipisicing elit, sed do eiusmod | tempor incididunt | ut labore et | dolore magna aliqua. | Ut enim ad minim veniam, quis nostrud | exercitation ullamco | laboris nisi ut | aliquip ex ea commodo | consequat.

How Does One Make Scala Control Abstraction in Repeat Until?

Hi I am Peter Pilgrim. I watched Martin Odersky create a control abstraction in Scala. However I can not yet seem to repeat it inside IntelliJ IDEA 9. Is it the IDE? package demo class Control { def repeatLoop ( body: = Unit ) = new Until( body ) class Until( body: = Unit ) { def until( cond: = Boolean ) { body; val value: Boolean = cond; println("value="+value) if ( value ) repeatLoop(body).until(cond) // if (cond) until(cond) } } def doTest2(): Unit = { var y: Int = 1 println("testing ... repeatUntil() control structure") repeatLoop { println("found y="+y) y = y + 1 } { until ( y < 10 ) } } } The error message reads: Information:Compilation completed with 1 error and 0 warnings Information:1 error Information:0 warnings C:\Users\Peter\IdeaProjects\HelloWord\src\demo\Control.scala Error:Error:line (57)error: Control.this.repeatLoop({ scala.this.Predef.println("found y=".+(y)); y = y.+(1) }) of type Control.this.Until does not take parameters repeatLoop { In the curried function the body can be thought to return an expression (the value of y+1) however the declaration body parameter of repeatUntil clearly says this can be ignored or not?

how can a Win32 App plugin load its DLL in its own directory

- by Jean-Denis Muys

My code is a plugin for a specific Application, written in C++ using Visual Studio 8. It uses two DLL from an external provider. Unfortunately, my plugin fails to start because the DLLs are not found (I put them in the same directory as the plugin itself). When I manually move or copy the DLLs to the host application directory, then the plugin loads fine. This moving was deemed unacceptably cumbersome for the end user, and I am looking for a way for my plugin to load its DLLs transparently. What can I do? Relevant details: the host Application plugins are located in a directory mandated by the host application. That directory is not in the DLL search path and I don't control it. The plugin is itself packaged as a subdirectory of the plugin directory, holding the plugin code itself, but also any resource associated with the plugin (eg images, configuration files…). I control what's inside that subdirectory, called a "bundle", but not where it's located. the common plugin installation idiom for that App is for the end user to copy the plugin bundle to the plugin directory. This plugin is a port from the Macintosh version of the plugin. On the Mac there is no issue because each binary contains its own dynamic library search path, which I set as I needed to for my plugin binary. To set that on the Mac simply involves a project setting in the Xcode IDE. This is why I would hope for something similar in Visual Studio, but I could not find anything relevant. Moreover, Visual Studio's help was anything but, and neither was Google. A possible workaround would be for my code to explicitly tell Windows where to find the DLL, but I don't know how, and in any case, since my code is not even started, it hasn't got the opportunity to do so. As a Mac developer, I realize that I may be asking for something very elementary. If such is the case, I apologize, but I have run out of hair to pull out.

ASP.NET MVC 2 - How do I use an Interface as the Type for a Strongly Typed View

- by Rake36

I'd like to keep my concrete classes separate from my views. Without using strongly typed views, I'm fine. I just use a big parameter list in the controller method signatures and then use my service layer factory methods to create my concrete objects. This is actually just fine with me, but it got me thinking and after a little playing, I realized it was literally impossible for a controller method to accept an interface as a method parameter - because it has no way of instantiating it. Can't create a strongly-typed view using an interface through the IDE either (which makes sense actually). So my question. Is there some way to tell the controller how to instantiate the interface parameter using my service layer factory methods? I'd like to convert from: [Authorize] [AcceptVerbs(HttpVerbs.Post)] [UrlRoute(Path = "Application/Edit/{id}")] public ActionResult Edit(String id, String TypeCode, String TimeCode, String[] SelectedSchoolSystems, String PositionChoice1, String PositionChoice2, String PositionChoice3, String Reason, String LocationPreference, String AvailableDate, String RecipientsNotSelected, String RecipientsSelected) { //New blank app IApplication _application = ApplicationService.GetById(id); to something like [Authorize] [AcceptVerbs(HttpVerbs.Post)] [UrlRoute(Path = "Application/Edit/{id}")] public ActionResult Edit(String id, IApplication app) { //Don't need to do this anymore //IApplication _application = ApplicationService.GetById(id);

Whatfor Visual Studio?! ml, cl, and link exe-cutables would suffice

- by AntonIO

It says in /library article /9s7c9wdw : "You can start this tool [cl.exe] only from the Visual Studio command prompt. You cannot start it from a system command prompt or from Windows Explorer." The corresponding (v=VS.80) page geared towards Visual Studio 2005 makes no such mention. Moreover, there is this Q&A. Thing is: Why should anybody spend anything on VS? ml is provided free of charge- necessarily so since it poses no value addition. The combined size of the other two is 895kb. Uncompressed. The GUI is a disservice. I myself have found half a dozen bugs. However, if the above is true, you'd need the IDE. MSFT fanboys, please step up. Background is that I have the 2008 Pro ed. The official Firefox builds use VS 2005 which I have on another system. To me no redundancy is acceptable. That's when I started pondering about boiling down VS and merely copying over the essential binaries. Then extended the thought to synthetically updating V$.

Qt4Dotnet on Mac OS X

- by Tony

Hello everyone. I'm using Qt4Dotnet project in order to port application originally written in C# on Linux and Mac. Port to Linux hasn't taken much efforts and works fine. But Mac (10.4 Tiger) is a bit more stubborn. The problem is: when I try to start my application it throws an exception. Exception states that com.trolltech.qt.QtJambi_LibraryInitializer is unable to find all necessary ibraries. QtJambi library initializer uses java.library.path VM environment variable. This variable includes current working directory. I put all necessary libraries in a working directory. When I try to run the application from MonoDevelop IDE, initializer is able to load one library, but the other libraries are 'missing': An exception was thrown by the type initializer for com.trolltech.qt.QtJambi_LibraryInitializer --- java.lang.RuntimeException: Loading library failed, progress so far: No 'qtjambi-deployment.xml' found in classpath, loading libraries via 'java.library.path' Loading library: 'libQtCore.4.dylib'... - using 'java.library.path' - ok, path was: /Users/chin/test/bin/Debug/libQtCore.4.dylib Loading library: 'libqtjambi.jnilib'... - using 'java.library.path' Both libQtCore.4.dylib and libqtjambi.jnilib are in the same directory. When I try to run it from the command prompt, the initializer is unable to load even libQtCore.4.dylib. I'm using Qt4Dotnet v4.5.0 (currently the latest) with QtJambi v4.5.2 libraries. This might be the source of the problem, but I'm neither able to compile Qt4Dotnet v4.5.2 by myself nor to find QtJambi v4.5.0 libraries. Project's page states that some sort of patch should be applied to QtJambi's source code in order to be compatible with Mono framework, but this patch hasn't been released yet. Without this patch application crashes in a strange manner (other than library seek fault). I must note that original QtJambi loads all necessary libraries perfectly, so it might be issues of IKVM compiler used to translate QtJambi into .Net library. Any suggestions how can I overcome this problem?

Using ZLib unit to compress files vs using ZipForge

- by user193655

There are many questions on zipping in Delphi, anyway this is not a duplicate. I am using ZipForge for zip/unzip capability in my application. Currently I use 2 features of ZipForge: 1) zip and unzip (!) 2) password protect the archives Now I am removing the password from all the archives so I need only to zip and unzip files. I zip them just for minimizing bandwith when uploading/downloading files from the server. So my idea is to process all files once for unzipping them (with password) and rezipping them without password. I have nothing against ZipForge, anyway it is an extra component, every time I upgrade to a newest Delphi version I have to wait for the new IDE support and moreover the more components the more problems during the installation. So since what I do is very simple I'd like to replace ZipForge with 2 simple functinos using the ZLib unit. I found (and tested) the functions here on Torry's. What do you think of using Zlib unit? Do you see any potential problem that I would not have with ZipForge? Can you comment on speed?

Why PHPUnit test doesn't fail?

- by JohnM2

I have a test method which looks like that: $row = $this->GetRowFromUserTable($id); $this->asserLessThan(time(), time($row['last_update'])); When $row is null access to $row['last_update'] should trigger a NOTICE and this test should fail, but it doesn't. This code fails on first assert, so I know $db_row is null (fixture is the same): $row = $this->GetRowFromUserTable($id); $this->asserNotNull($row); $this->asserLessThan(time(), time($row['last_update'])); When I write this: $row = $this->GetRowFromUserTable($id); $this->assertEquals(E_ALL, error_reporting()); $this->asserLessThan(time(), time($row['last_update'])); it successes, so I am also sure that error_reproting is right and this situation must have something to do with PHPUnit. I use PHPUnit 3.5.6 I read this question: Can I make PHPUnit fail if the code throws a notice? but the answer suggests to use newer version of PHPUnit, but that answer is from 2009, so it's not it. EDIT: I use NetBeans IDE 6.9.1 to run my test.

Xlib.h and Xutil.h not found in Eclipse, how can I fix this?

Hi, I'm a newbie to Eclipse IDE for C/C++ development. I just installed MingW and set it up as my system's environment variable. I am trying to make an application that uses the X library but eclipse cant seem to find it. Eclipse works with any other simple standard library functions but it cant find the X library. Please Help! Here's a sample code snippet that's failing: #include <stdio.h> #include <X11/Xlib.h> // Can't find this #include <X11/Xutil.h> // Or this... int main() { printf("Hello"); return 0; } Do I have to download the X library from somewhere? If so then from where and where do I paste it to? Please tell me what to do in order for me to start coding using the Xlib in Eclipse. If you find any useful links, please dont hesitate to post. Thanks.

Strange build issue using Flex Mojo. Looking for troubleshooting suggestions.

- by WeeJavaDude

I have ran into a strange issue and I was hoping for some suggeestion on how to attack the problem. Here is the environment. 1) We develop locally using Flex Builder. 2) We use QuickBuild with FlexMojo 3.4.2 for test builds and production 3) In both cases we don't believe optimization is enabled. What we are seeing is some strange behavior relating to the Ctrl-Enter key when doing testing on IE only in our test environment but not locally. By copying some files over locally I have narrowed the issue down to swf files differences. We do see a difference in the size of swf files in our test environment vs our local environments. Couple things that would help me in troubleshooting would be. 1) Is there a way to know what exactly is in the SWF file? What SWCs are included. 2) How does one compare compile settings between a maven mojo configuration and Flex IDE envioronment? Any thoughts or opinions would be very helpful.
