• How do I deploy a utility with ocx dependency to a test machine without registering the ocx?

  - by Brandon

  I have a test utility that depends upon an ocx file that is installed/registered on my development machine. We'd like to run this tool on a test machine without polluting the machine with any unnecessary files. Nothing should be installed except the target machine software. Running the tool on a network drive or from a stand-alone directory copied to the test machine would be ideal. But, registering the ocx on the test machine is out of the question. Placing the ocx file in the same directory as the exe doesn't work. No matter what it still gives me this error--"The application has failed to start because the application configuration is incorrect. Reinstalling the application may fix the problem." What else can I try?

• Python in AWS Elastic Beasntalk: Private package dependencies

  - by Adam Matan

  I would like to deploy a Python Flask application on beanstalk. The application depends on external packages (e.g. geopy) and internal packages (e.g. adam_geography). The manual Create a requirements.txt file and place it in the top-level directory of your source bundle. This would probably fetch geopy and its dependencies, but would not fetch adam_geography which is available from a custom repo inside my VPC. How do I specify/upload private, internal Python package dependencies in a Beanstalk application?

• EPOC EMOTIV cognitive suite is user dependent or independent

  - by Varun Malhotra

  After working a bit with EPOC EMOTIV, i suspect that its cognitive suite is user dependent, though its other suites are not and work absolutely well in all cases. It's use in cognitive area is wide and many such applications have also been developed. BCI CAD 3D geometry shapes are also a good example. But the main issue i want to highlight is that is it's cognitive suite depends on a particular set of data( same set always). I want to work more deeper with cognitive suite so any help(suggestions, research papers, EEG data processing), anything which can be a great source to deal with. Thanks!

• Whats are basic things you should kept in mind while writing functional tests?

  - by piemesons

  Hello, what kind of functionality should be covered in functional test? How to prioritize what are the functionality that must be covered in functional test. I can understand it depends upon on the project, whats the functionality present the project. Lets take a example of stackoverflow. Suppose we are developing a basic working model of this. What kind of functional test must be covered in this. Just brief what the key points while writing functional tests. (taking any basic functionality from this site just to understand the reference) Still its platform independent question.I am using ruby on rails developer, but keeping ruby on rails as mind will be preferable.

• How to color a mesh with values at the vertices in WPF 3D?

  - by Christo

  We've got a sphere which we want to display in 3D and color given a fuction that depends on spherical coordinates. The sphere was triangulated using a regular grid in (theta, phi), but this produced a lot of small triangles near the poles. In an attempt to reduce the number triangles at the poles, we've changed out mesh generation to produce more evenly sized triangles over the surface. The first triangulation method had the advantage that we could easily create a texture and drape it over the surface. It seems that in WPF it isn't possible to assign colors to vertices the way one would go about in OpenGL or Direct3D. With the second triangulation method it isn't apparent how to go about generating the texture and setting the texture coordinates, since the vertices aren't aligned to a grid anymore. Maybe it would be possible to create a linear texture containing a color for each vertex, but then how will that effect the coloring? Will it still render smoothly over the triangle surfaces as one would expect by applying per vertex coloring?

• How can I compile an autotools project with statically linked dependancies?

  - by flyx

  There's an open source library I want to use. As I want to spread my software as binary package, I do not want the library to have dependancies on other libraries, so I need to link the dependancies statically. Now as the library is open source and there are no binaries provided, I compile it myself. The library uses autotools, and I didn't find any useful documentation on how to link dependancies statically. What I did try is to call the configure script with --enable-static, but this apparently only tells configure to compile a static version of the library - but what I need is a dynamic library that includes all the libraries it depends on. So, I need a way to either tell configure to link against dependancies statically, or a way to post-process the built library to include all dependancies. Can anyone tell me how to do this? Oh, and if it matters: I'm on 64bit Snow Leopard.

• rewrite image URLs

  - by Don

  Hi, I'm writing a Maven plugin that merges CSS files together. So all the CSS files that match /foo/bar/*.css might get merged to /foo/merged.css. A concern is that in a file such as /foo/bar/baz.css there might be a property such as: background: url("images/pic.jpg") So when the file is merged into /foo/merged.css this will need to be changed to background: url("bar/images/pic.jpg") The recalculated URL obviously depends on 3 factors: original URL original CSS file location merged CSS file location Assuming that the original and merged CSS files are both on the same filesystem, is there a general formula (or Java library) that can be used to calculate the new url given these 3 inputs? Thanks, Don

• What happens when a computer program runs?

  - by gaijinco

  I know the general theory but I can't fit in the details. I know that a program resides in the secondary memory of a computer. Once the program begins execution it is entirely copied to the RAM. Then the processor retrive a few instructions (it depends on the size of the bus) at a time, puts them in registers and executes them. I also know that a computer program uses two kinds of memory: stack and heap, which are also part of the primary memory of the computer. The stack is used for non-dynamic memory, and the heap for dynamic memory (for example, everything related to the new operator in C++) What I can't understand is how those two things connect. At what point is the stack used for the execution of the instructions? Instructions go from the RAM, to the stack, to the registers?

• C++ : size of int, long, etc...

  - by Jérôme

  I'm looking for detailed informations regarding the size of basic C++ types. I know that it depends on the architecture (16 bits, 32 bits, 64 bits) and the compiler. But are there any standards ? I'm using Visual Studio 2008 on a 32 bit achitecture. Here is what I get : char : 1 byte short : 2 bytes int : 4 bytes long : 4 bytes float : 4 bytes double : 8 bytes I tried to find, without much success, reliable informations telling the sizes of char, short, int , long, double, float (and other types I don't think of) under different architecture and compiler.

• Environment Variable to determine the OS type (Windows XP, Windows 7)

  - by Santhosh

  I want to differrntiate between Windows XP and Windows 7 in a XML file. Thought i will use an environment variable for it inside the XML. However I could not find any system environment variable defined in windows that gives this information. I see the %OSTYPE% variable but it is only available in Windows 7. It is not defined in XP. Is there anyway i could do this? Note that i would like a solution which purely depends on system environment variables. I do not want to create new variables based on executing some command, because i want to use this variable in a XML file.

• How do I get the path of the current executed file in python?

  - by Sorin Sbarnea

  This may seam a newbie question but it is not. It looks that common approaches are not always working: Currently I know only two options but none of them looks to work an all cases. sys.argv[0] This means using path = os.path.abspath(os.path.dirname(sys.argv[0])) but this does not work if you are running from another python script from another directory, and this can really happen in real life. __file__ this means that path = os.path.abspath(os.path.dirname(__file__)) but I found that this doesn't work: py2exe that doesn't have a __file__ attribute but there is an workaround. when you run from IDLE with execute() there is no __file__ attribute OS X 10.6 where I get NameError: global name '__file__' is not defined Related questions with incomplete answers: http://stackoverflow.com/questions/1296501/python-find-path-to-file-being-run http://stackoverflow.com/questions/1483827/python-path-to-current-file-depends-on-how-i-execute-the-program http://stackoverflow.com/questions/2259503/how-to-know-the-path-of-the-running-script-in-python http://stackoverflow.com/questions/509742/python-chdir-to-dir-the-py-script-is-in

• Question about OOP and objects.

  - by loddn

  I have a school assignment, a Dog Show. My assignment is to create a website where vistors can display results and Judges and Secretary can admin, crud. I have a small problem one part of the assignment. The result should be based on two protokols from different judges and after that checked by the secretary before the result is displayed for the user. I have to say i'm fairly new to programming and so i need some smart suggestions on how to design and implement this. The assignment should cover both a db and c# (.net mvc). Q1: How do i create a object (result)that depends on two other objects(protocol)? Is that even needed? Q2: How to solve this in a relational db?

• pass custom environment variables to System.Diagnostics.Process

  - by Mike Ruhlin

  I'm working on an app that invokes external processes like so: ProcessStartInfo startInfo = new ProcessStartInfo(PathToExecutable, Arguments){ ErrorDialog = false, RedirectStandardError = true, RedirectStandardOutput = true, UseShellExecute = false, CreateNoWindow = true, WorkingDirectory = WorkingDirectory }; using (Process process = new Process()) { process.StartInfo = startInfo; process.Start(); process.BeginErrorReadLine(); process.BeginOutputReadLine(); process.WaitForExit(); return process.ExitCode; } One of the processes I'm calling depends on an environment variable that I'd rather not require my users to set. Is there any way to modify the environment variables that get sent to the external process? Ideally I'd be able to make them visible only to the process that's running, but if I have to programmatically set them system-wide, I'll settle for that (but, would UAC force me to run as administrator to do that?) ProcessStartInfo.EnvironmentVariables is read only, so a lot of help that is...

• Maven - add dependency on artifact source

  - by Jacob Hansson

  I have two maven modules, one that ends up as a jar, and one war that depends on that jar. I want the jar module to package it's source code together with the compiled classes in the jar, so that the second module is able to access it. I have tried using the maven-source-plugin, but I am confused as to how to add a dependency on the output of that. It seems that the dependency by default goes to the compiled jar, and not the source-code jar (ending with "-source.jar") that maven-source-plugin creates. How do I add the "-source.jar" as a dependency, while still preserving the dependency on the compiled sources?

• Dll only loads correctly via LoadLibrary?

  - by Steve

  I'm trying to use dbghelp.dll. If I set it up in the VS2008 properties to point to the correct library and header file, and put dbghelp.dll in the same directory as the executable, one of the functions in the dll fails. If I LoadLibrary the dll, everything that function works. I've looked at the header that gets included via the VS option, and the right one is being pulled in. The correct lib is being pulled in (checked via /verbose option), and depends.exe shows the correct dll is loaded. Does anyone know why I can't get this to work? I'll probably just go with LoadLibrary, but I'm genuinely stumped on this one. EDIT: SymfromAddr fails with an "error 87", whatever that is. If I load the dll via LoadLibrary, it works.

• Oracle - Determine maximum supported size for regular expression

  - by FrustratedWithFormsDesigner

  I have a regular expression that throws ORA-12733, "regular expression is too long". How do I determine what the maximum supported size is? FYI: the offending regex is 892 characters. It's a generated regex, so I could change how I generate and execute it, but I would like to know what the limits to the max size are before I change how I am generating and executing. (running Oracle 10.2g) UPDATE: If it depends on the actual regex, here's the begining of it (the rest is just the same thing repeated, with different values between ^ and $): (^R_1A$|^R_2A$|^R_3A$|^R_4A$|^R_4B$|^R_5A$|^R_5B$...

• Using Linq to SQL change events with attribute-based mapping

  - by R Mene

  I'm writing a new ASP.NET MVC2 application using Linq to SQL. This application depends on an existing SQL database. I am using attribute-based mapping to map my database fields to my Linq to SQL entities. I also need to make use of Linq to SQL's On[Property]Changed methods so I can perform change-auditing of database tables within my application. Whereas the documentation explains how to do this when using Linq to SQL's ORM and dbml files (i.e. by writing partial classes), it is not clear how to do with when using attribute-based mapping or when using XML-based mapping. It would be very helpful if someone could describe how to do this.

• Is there a way to fix the width of drop down list?

  - by Harry Pham

  Here is what I got: <select id="box1"> <option>ABCDEFG</option> </select> <select id="box2"> <option>ABCDEFGHIJKLMNO</option> </select> I have 2 different Drop Down lists. Since the width of a drop down list depends on the width of the longest text in the option, I end up with 2 drop down lists with 2 different widths. This makes my webpage look goofy. What I want is to set it so that both of my drop down lists will have the same width (I'd prefer the width to be very long, so that even the longest item won't be truncated).

• How do I prevent JAXB from generating Java from imported schema?

  - by Mark

  I've got two Java projects, both generate Java classes based on a schema definition, I'm using xjc to create the classes. My second project depends on a class from the first project, and in particular, one of the classes I'd like to generate in my second project needs to use one of the types from the first project. To accomplish this dependency at the schema level, I'm using a simple xsd:import to map the namespace to a particular schema. JAXB works just fine with this condition, except it also generates the first project's types in the second project. So after running have something like this: Project A +-- com.foo.bar +-- TypeA Project B +-- com.foo.asdf +-- TypeB +-- com.foo.bar +-- TypeA The second "TypeA" is undesirable, and I'd like to never generate it in the first place. How do I instruct JAXB not to generate the classes for "TypeA" that it finds as a result of the import statement?

• C++ conditional compilation

  - by Shaown

  I have the following code snippet #ifdef DO_LOG #define log(p) record(p) #else #define log(p) #endif void record(char *data){ ..... ..... } Now if I call log("hello world") in my code and DO_LOG isn't defined, will the line be compiled, in other words will it eat up the memory for the string "hello world"? P.S. There are a lot of record calls in the program and it is memory sensitive, so is there any other way to conditionally compile so that it only depends on the #define DO_LOG? Thanks in advance.

• select from multiple tables with different columns

  - by Qaiser Iftikhar

  Say I got this sql schema. Table Job: id,title, type, is_enabled Table JobFileCopy: job_id,from_path,to_path Table JobFileDelete: job_id, file_path Table JobStartProcess: job_id, file_path, arguments, working_directory There are many other tables with varying number of columns and they all got foreign key job_id which is linked to id in table Job. My questions: Is this the right approach? I don't have requirement to delete anything at anytime. I will require to select and insert mostly. Secondly, what is the best approach to get the list of jobs with relevant details from all the different tables in a single database hit? e.g I would like to select top 20 jobs with details, their details can be in any table (depends on column type in table Job) which I don't know until runtime. Thanks in advance. Regards,

• Where does ASP.Net get its rendered IDs from?

  - by NeilD

  Hi, I've inherited a project with some nasty JavaScript that depends on hard coded object ids. i.e. There are lots of places where it does things like this var magazine = document.getElementById('repModuleDisplay__ctl3_chkCats_0'); When the page renders in my UAT environment, the HTML looks like this, and everything works OK. <input id="repModuleDisplay__ctl3_chkCats_0" type="checkbox" name="repModuleDisplay:_ctl3:chkCats:0" ... etc However, when I put it on my Production environment, the HTML is suddenly rending like this: <input id="repModuleDisplay_ctl03_chkCats_0" type="checkbox" name="repModuleDisplay$ctl03$chkCats$0" ... etc The difference in ids means that the JavaScript can't find the Element, and fails. In an ideal world, I'd scrap the buggy JavaScript and do it again properly, but for a quick fix, I'd like to know what is causing the difference in rendering between the two environments. Does anyone have any ideas? Thanks, Neil

• Not able to generate correct build.xml for android test project

  - by user338656

  Hi, I have created a main android project using "android" utility. e.g. android create project --target 1 --name MyApp --path C:\testandroid\myui --activity LaunchActivity --package com.myui.activity build.xml got generated fine (has ant targets like debug, release etc) I generated a test android project (which depends on main project). I used "android" utility to do that. e.g. android create test-project --path C:\testandroid\myuitest --main ..\myui --name MfAppTest build.xml got generated but incorrect (does not have targets like run-tests). It has same targets as main project. Can someone help as where is the problem? Thx. Ashley

• Can I safely move my project to .NET 4.0?

  - by Decker

  I've migrated my project to VS2010 but have not yet targeted .NET 4.0. It's currently targeting 3.5 SP1 (and CLR 2). The project relies on several third party components -- mostly open source -- that were presumably built against the 2.0 CLR. Can I simply retarget my project to the 4.0 runtime? Or do I have to get new versions of all the referenced assemblies on which it depends? I've read a little about the new in-process side-by-side feature of .NET 4.0, but I don't think it applies here (the example I read was about two different .NET plug ins to an office application). My situation is different. My solution directly references assemblies and I wouldn't think side-by-side applies -- unless I don't understand its purpose. TIA
