  • Java: separating JAR versions

    - by Chris
    I'm developing a Java plugin for an existing Java program. The existing program uses a specific version of eclipse.uml2.* and my plugin does too. Unfortunately I need a newer version for my plugin. In order to run the plugin, I need to export it into a Jar file (with all jars packed). Then the program executes it. But somehow the new eclipse.uml2.* seem to interfere with the program - it crashes. Is there a way to "separate" both versions of the jar files?

  • Factory Pattern: Determining concrete factory class instantiation?

    - by Chris
    I'm trying to learn patterns and I'm stuck on determining how or where a Factory Pattern determines what class to instanciate. If I have a Application that calls the factory and sends it, say, an xml config file to determine what type of action to take, where does that logic for interpreting the config file happen? THE FACTORY using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace myNamespace { public abstract class SourceFactory { abstract public UploadSource getUploadSource(); } public class TextSourceFactory : SourceFactory { public override UploadSource getUploadSource() { return new TextUploadSource(); } } public class XmlSourceFacotry : SourceFactory { public override UploadSource getUploadSource() { return new XmlUploadSource(); } } public class SqlSourceFactory : SourceFactory { public override UploadSource getUploadSource() { return new SqlUploadSource(); } } } THE CLASSES using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace myNamespace { public abstract class UploadSource { abstract public void Execute(); } public class TextUploadSource : UploadSource { public override void Execute() { Console.WriteLine("You executed a text upload source"); } } public class XmlUploadSource : UploadSource { public override void Execute() { Console.WriteLine("You executed an XML upload source"); } } public class SqlUploadSource : UploadSource { public override void Execute() { Console.WriteLine("You executed a SQL upload source"); } } }

  • How to delete a user in MSCRM 4.0

    - by Chris Richner
    Do you know of a way to get rid of CRM User accounts in MSCRM 4.0? After some user accounts have been deleted in AD we're faced a lot of issues while importing the organisation to another server stating that there are issues with the user mapping. What kind of idea is behind the fact that no user accounts can be deleted from the crm installation? Is there any tool or undocumented Webservice API call to get rid of crm users? Thanks for sharing yours insights

  • Sharing output streams through a JNI interface

    - by Chris Conway
    I am writing a Java application that uses a C++ library through a JNI interface. The C++ library creates objects of type Foo, which are duly passed up through JNI to Java. Suppose the library has an output function void Foo::print(std::ostream &os) and I have a Java OutputStream out. How can I invoke Foo::print from Java so that the output appears on out? Is there any way to coerce the OutputStream to a std::ostream in the JNI layer? Can I capture the output in a buffer the JNI layer and then copy it into out?

  • qtableview (libqt) how do I correctly create a QModelIndex

    - by Chris Camacho
    I'm trying to enter edit mode on a specific cell like this void MainWindow::on_addButton_released(void) { tm->addRow(); tableView->scrollToBottom(); int ec=tm->firstWritableColumn(); int r=tm->rowCount(QModelIndex()); QModelIndex id = tm->index(r, ec, QModelIndex()); tableView->setCurrentIndex(id); tableView->edit(id); qDebug() << "row:" << r << " col:" << ec << "index:" << id; } my model creates an index like this QModelIndex TableModel::index(int row,int column,QModelIndex parent) const { Q_UNUSED(parent); return createIndex(row,column,0); } the debug output looks like this row: 9 col: 1 index: QModelIndex(9,1,0x0,TableModel(0xbf3f50) ) I'm fairly sure that the index is somehow invalid as setCurrentIndex doesn't seem to be working

  • Dynamically pixelate an html image element

    - by Chris Armstrong
    I'm to take an image on a webpage, and then use javascript (or whatever would be best suited) to dynamically 'pixelate' it (e.g. into 20px squares). Then, as the user scrolls down the page, I need the image to gradually increase in resolution, till it is no longer pixelated. Any ideas how I could go about doing this? I realise I could use php to resize an image and several times and just switch out the image, but that would require loading several extra images. Also, I know I could probably do the effect with flash & pixelbender, but I want to achieve it within the limitations of HTML5, CSS & Javascript if possible. Appreciate any thoughts!

  • How much of the "Objective-C" I'm learning is universal Objective-C, and not Apple's frameworks?

    - by Chris Cooper
    This question is related to one of my others about C: What can you do in C without “std” includes? Are they part of “C,” or just libraries? I've become curious lately as to what is really contained the the core Objective-C language, and what parts of the Objective-C I've done for iPhone/OS X development is specific to Apple platforms. I know that things like syntax are the same, but for instance, is NSObject and its torrent of NS-subclasses actually part of "standard" Objective-C? Could I use them in, say, Windows? What parts are universal for the most part, and what parts would I only find on an Apple platform? If you want, giving an example of Objective-C used elsewhere as an example of what is more "universal" would help me as well. Thanks! =)

  • Representing Sparse Data in PostgreSQL

    - by Chris S
    What's the best way to represent a sparse data matrix in PostgreSQL? The two obvious methods I see are: Store data in a single a table with a separate column for every conceivable feature (potentially millions), but with a default value of NULL for unused features. This is conceptually very simple, but I know that with most RDMS implementations, that this is typically very inefficient, since the NULL values ususually takes up some space. However, I read an article (can't find its link unfortunately) that claimed PG doesn't take up data for NULL values, making it better suited for storing sparse data. Create separate "row" and "column" tables, as well as an intermediate table to link them and store the value for the column at that row. I believe this is the more traditional RDMS solution, but there's more complexity and overhead associated with it. I also found PostgreDynamic, which claims to better support sparse data, but I don't want to switch my entire database server to a PG fork just for this feature. Are there any other solutions? Which one should I use?

  • Get remote image using cURL then resample.

    - by Chris
    I want to be able to retrieve a remote image from a webserver, resample it, and then serve it up to the browser AND save it to a file. Here is what I have so far: $ch = curl_init(); // set URL and other appropriate options curl_setopt($ch, CURLOPT_URL, "$rURL"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HEADER, 0); // grab URL and pass it to the browser $out = curl_exec($ch); // close cURL resource, and free up system resources curl_close($ch); $imgRes = imagecreatefromstring($out); imagejpeg($imgRes, $filename, 70); header("Content-Type: image/jpg"); header("Content-length: ".filesize($filename)); header("Content-Transfer-Encoding: binary"); header("Content-Length: ".filesize($filename)); readfile("$filename"); exit(); Update Updated code to include imjpeg step to save the image as lower quality. But how do I then, efficiently, serve this up to the browser. I currently, later in the code, do this readfile("$filename"); along with some header information but that means I'm reading the file back in again which seems inefficient.

  • IE8 Debugger: how to load external javascript files?

    - by Chris Barnhill
    I have downloaded and installed IE8. I was playing around with the debugger, but I could not figure out how to load external javascript files. It displays the javascript from the main page, but I need to debug the script in the external files. I have googled various articles that show a screenshot of an IE8 debugger with a drop-down for selecting which script to debug, but my debugger does not feature this. Can anyone help me with this? Thanks.

  • How to determine the data type of a CvMat

    - by Chris
    When using the CvMat type, the type of data is crucial to keeping your program running. For example, depending on whether your data is type float or unsigned char, you would choose one of these two commands: cvmGet(mat, row, col); cvGetReal2D(mat, row, col); Is there a universal approach to this? If the wrong data type matrix is passed to these calls, they crash at runtime. This is becoming an issue, since a function I have defined is getting passed several different types of matrices. How do you determine the data type of a matrix so you can always access its data? I tried using the "type()" function as such. CvMat* tmp_ptr = cvCreateMat(t_height,t_width,CV_8U); std::cout << "type = " << tmp_ptr->type() << std::endl; This does not compile, saying "term does not evaluate to a function taking 0 arguments". If I remove the brackets after the word type, I get a type of 1111638032 EDIT minimal application that reproduces this... int main( int argc, char** argv ) { CvMat *tmp2 = cvCreateMat(10,10, CV_32FC1); std::cout << "tmp2 type = " << tmp2->type << " and CV_32FC1 = " << CV_32FC1 << " and " << (tmp2->type == CV_32FC1) << std::endl; } Output: tmp2 type = 1111638021 and CV_32FC1 = 5 and 0

  • StructureMap resolve dependency through injection instead of service location

    - by Chris Marisic
    In my project I register many ISerializers implementations with the assembly scanner. FWIW this is the code that registers my ISerializers Scan(scanner => { scanner.AssemblyContainingType<ISerializer>(); scanner.AddAllTypesOf<ISerializer>().NameBy(type => type.Name); scanner.WithDefaultConventions(); }); Which then correctly registers ISerializer (...ISerializer) Scoped as: Transient JsonSerializer Configured Instance of ...JsonSerializer BsonSerializer Configured Instance of ...BsonSerializer And so forth. Currently the only way I've been able to figure out how to resolve the serializer I want is to hardcode a service location call with jsonSerializer = ObjectFactory.GetNamedInstance<ISerializer>("JsonSerializer"); Now I know in my class that I specifically want the jsonSerializer so is there a way to configure a rule or similar that says for ISerializer's to connect the named instance based on the property name? So that I could have MySomeClass(ISerializer jsonSerializer, ....) And StructureMap correctly resolve this scenario? Or am I approaching this wrong and perhaps I should just register the concrete type that implements ISerializer and then just specifically use MySomeClass(JsonSerializer jsonSerializer, ....) for something along these lines with the concrete class?

  • Java Future and infinite computation

    - by Chris
    I'm trying to optimize an (infinite) computation algorithm. I have an infinte Sum to calculate ( Summ_{n- infinity} (....) ) My idea was to create several threads using the Future < construct, then combine the intermediate results together. My problem hoewer is that I need a certain precision. So I need to constantly calculate the current result while other threads keep calculating. My question is: Is there some sort of result queue where each finished thread can put its results in, while a main thread can receive those results and then either lets the computation continues or terminate the whole ExecutorService? Any Help would really be appreciated! Thanks!

  • Why do multiline cells in my CSV file appear with a question mark at the end of each line in Excel?

    - by Chris Lindsay
    I'm currently working on a project where we'd like to allow a user to export their data to CSV. Some of the data we present has multiple values for a single cell, and so we use the standard CSV method of putting each value on its own line: Column A, Column B, Column C Value A, "Value B1 Value B2", Value C Most of the time this works fine, but some people are reporting seeing a small question mark in a box character appear at the end of each line when they load the file in Excel. Why is this happening?

  • Javafx - Clipview to a Group?

    - by Chris-NTA
    Can I apply clipview to a vertical expanding Group? Time to time I'm appending text to a group and want to use scrollbar to navigate in that group. The scrollbar part is working when I assign it to the group itself but want to limit the size of the group by using clipview. Anyone having experience in this?

  • Shortest-path algorithms which use a space-time tradeoff?

    - by Chris Mounce
    I need to find shortest paths in an unweighted, undirected graph. There are algorithms which can find a shortest path between two nodes, but this can take time. There are also algorithms for computing shortest paths for all pairs of nodes in the graph, but storing such a lookup table would take lots of disk space. What I'm wondering: Is there an algorithm which offers a space-time tradeoff that's somewhere between these two extremes? In other words, is there a way to speed up a shortest-path search, while using less disk space than would be occupied by an all-pairs shortest-path table? I know there are ways to efficiently store lookup tables for this problem, and I already have a couple of ideas for speeding up shortest-path searches using precomputed data. But I don't want to reinvent the wheel if there's already some established algorithm that solves this problem.

  • Lazy Loading wpf Combobox items

    - by Chris McGrath
    I have an IEnumerable< which lazy loads it's data. I want to just set a Combobox's ItemsSource to the IEnumerable, but when I do it goes and loads all the data anyway (which removes the point of lazy loading). I've tried it with Linq-To-Sql as well since it seems to be a similar theory and it also loads all the data. Is there an easy way to do this?

  • Silverlight solution builds in VS2008 but fails with MSBuild

    - by Chris Nicola
    I have a Silverlight solution that I want to create a build script for. I have a simple script that looks like this call "c:\Program Files\Microsoft Visual Studio 9.0\VC\bin\vcvars32.bat" msbuild %CD%\V1\Incentive.sln /target:Rebuild /property:Configuration=DEBUG;WarningLevel=2 msbuild %CD%\UI\IncentiveUI.sln /target:Rebuild /property:Configuration=DEBUG;WarningLevel=2 pause However when I run this I get a failure, with some complaints about classes that are in a project with linked files: http://pastebin.com/JRE3tWfh This solution compiles fine in VS2008 so I can't figure out what the problem is. I have to guess something is wrong with the way I am using msbuild here.

  • strange redefined symbols

    - by Chris H
    I included this header into one of my own: http://codepad.org/lgJ6KM6b When I compiled I started getting errors like this: CMakeFiles/bin.dir/SoundProjection.cc.o: In function `Gnuplot::reset_plot()': /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.4/include/g++-v4/new:105: multiple definition of `Gnuplot::reset_plot()' CMakeFiles/bin.dir/main.cc.o:project/gnuplot-cpp/gnuplot_i.hpp:962: first defined here CMakeFiles/bin.dir/SoundProjection.cc.o: In function `Gnuplot::set_smooth(std::basic_string, std::allocator const&)': project/gnuplot-cpp/gnuplot_i.hpp:1041: multiple definition of `Gnuplot::set_smooth(std::basic_string, std::allocator const&)' CMakeFiles/bin.dir/main.cc.o:project/gnuplot-cpp/gnuplot_i.hpp:1041: first defined here CMakeFiles/bin.dir/SoundProjection.cc.o:/usr/include/eigen2/Eigen/src/Core/arch/SSE/PacketMath.h:41: multiple definition of `Gnuplot::m_sGNUPlotFileName' I know it's hard to see in this mess, but look at where the redefinitions are taking place. They take place in files like /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.4/include/g++-v4/new:105. How is the new operator getting information about a gnuplot header? I can't even edit that file. How could that ever even be possible? I'm not even sure how to start debugging this. I hope I've provided enough information. I wasn't able to reproduce this in a small project. I mostly just looking for tips on how to find out why this is happening, and how to track it down. Thanks.
