  • Generic dataset handling library

    - by Pep.
    Hello, I want to build a generic Perl module for handling and analysing biomedical character separated datasets and which can, most certain, be used on any kind of datasets that contain a mixture of categorical (A,B,C,..) and continuous (1.2,3,881..) and identifier (XXX1,XXX2...). The plan is to have people initialize the module and then use some arguments to point to the data file(s), the place were the analysis reports should be placed and the structure of the data. By structure of data I mean which variable is in which place and its name/type. And this is where I need some enlightenment. I am baffled how to do this in a clean way. Obviously, having people create a simple schema file, be it XML or some other format would be the cleanest but maybe not all people enjoy doing something like this. The solutions I can think of are: Create a configuration file in XML or similar and with a prespecified format. Pass the information during initialization of the module. Use the first row of the data as headers and try to guess types (ouch) Surely there must be a "canonical" way of doing this that is also usable and efficient. Thanks p.

  • Creating one row of information in excel using a unique value

    - by user1426513
    This is my first post. I am currently working on a project at work which requires that I work with several different worksheets in order to create one mail master worksheet, as it were, in order to do a mail merge. The worksheet contains information regarding different purchases, and each purchaser is identified with their own ID number. Below is an example of what my spreadsheet looks like now (however I do have more columns): ID Salutation Address ID Name Donation ID Name Tickets 9 Mr. John Doe 123 12 Ms. Jane Smith 100.00 12 Ms.Jane Smith 300.00 12 Ms. Jane Smith 456 22 Mr. Mike Man 500.00 84 Ms. Jo Smith 300.00 What I would like to do is somehow sort my data so that everythign with the same unique identifier (ID) lines up on the same row. For example ID 12 Jane Smith - all the information for her will show up under her name matched by her ID number, and ID 22 will match up with 22 etc... When I merged all of my spreadsheets together, I sorted them all by ID number, however my problem is, not everyone who made a donation bought a ticket or some people just bought tickets and nothing us, so sorting doesn't work. Hopefully this makes sense. Thanks in advance.

  • Custom Windows GUI library

    - by Luca Matteis
    I always wondered how software such as iTunes, Winamp etc is able to create its own UI. How is this accomplished under the Windows platform? Is there any code on the web explaining how one would create their own custom GUI?

  • Any AOP support library for Python ?

    - by edomaur
    I am trying to use some AOP in my Python programming, but I do not have any experience of the various libs that exists. So my question is : What AOP support exists for Python, and what are the advantages of the differents libraries between them ? Edit : I've found some, but I don't know how they compare : Aspyct Lightweight AOP for Python Edit2 : In which context will I use this ? I have two applications, written in Python, which have typically methods which compute taxes and other money things. I'd like to be able to write a "skeleton" of a functionnality, and customize it at runtime, for example changing the way local taxes are applied (by country, or state, or city, etc.) without having to overload the full stack.

  • Python 3.1 twitter post with installed library,

    - by Andrew
    I'd like to be able to post twitter messages from python 3.0. None of the twitter API I have looked at support python 3.1. Since the post proceedure only requires this : JSON: curl -u username:password -d status="your message here" http://api.twitter.com/1/statuses/update.json I was wondering if it is possible with the standard libraries to format this so a message could be sent. My head says it should be possible.

  • .net: does anyone know a free library to download nntp messages

    - by stighy
    hi folks, i'm using ip*works for download newsgroup message and insert them into a database... ipworks is "comfortable" to use because it automatically split nntp data return into different object (or variable). So i've "author" "date" "topic" "messagge" already splitted to my use. However ipworks isn't free and it cost a lot for my use.. so i'm asking you some component or code snippet to use to download and "manage" nntp messagges. Thanks in advance and regards!

  • Memory Leak from Foundation & CFNetwork Library

    - by Lakshmie
    I am using instruments to resolve memory leak issues for an app in iPhone. I just wanted to know if I have to resolve the leaks coming from Foundation and CFNetwork Libraries. Specifically, the leaks are from: 1. NSCFString 2. NSConcreteData 3. General Block-3584 Since they do not directly point to the code that I have written, how should I resolve them, if I have to? Thanks.

  • How to learn a C++ GUI library effectively?

    - by Chan
    Hello everyone, I have many options for GUI in my head while searching in stackoverflow, but these are what I chose among others: Qt gtkmm GTK+ I used GTK+ couple years ago, and I felt so painful when using C API without string object and containers. I prefer C++ style, I then switched to C++ gtkmm, but the documentation was bad at that time. I found no help when encountering an issue. Now I want to give a hard try for Qt4, but I really want to know how to learn a GUI librarie effectively. With core C++, I usually pick up a problem and try to solve it in different ways using that particular technique, functionality. On the other hand, after skimming through the documentation from Qt site, I don't think this way of studying is applicable, since the GUI classes and APIs are so much bigger. Plus I'm still in school, so I won't have much time to play all the day long with it. How do you guys learn GUI before? Can anyone share some experiences how they learn thing, that would be an invaluable input for me! Best regards, Chan Nguyen

  • P/Invoke or C++/CLI for wrapping a C library

    - by Ian G
    Have a moderate size (40-odd function) C API that needs to be called from a C# project. The functions logically break up to form a few classes that will be API presented to the rest of the project. Are there any objective reasons to prefer P/Invoke or C++/CLI for the interoperability underneath that API, in terms of robustness, maintainability, deployment, ...? The issues I could think of that might be, but aren't problematic are: C++/CLI will require an separate assembly, the P/Invoke classes can be in the main assembly. (We've already got multiple assemblies and there'll be the C dlls anyway so not a major issue). Performance doesn't seem differ noticeable between the two methods. Issues that I'm not sure about are: My feeling is C++/CLI will be easier to debug if there's inter-op problem, is this true? Language familiarity enough people know C# and C++ but knowledge of details of C++/CLI are rarer here. Anything else?

  • std::string.resize() and std::string.length()

    - by dreamlax
    I'm relatively new to C++ and I'm still getting to grips with the C++ Standard Library. To help transition from C, I want to format a std::string using printf-style formatters. I realise stringstream is a more type-safe approach, but I find myself finding printf-style much easier to read and deal with (at least, for the time being). This is my function: using namespace std; string formatStdString(const string &format, ...) { va_list va; string output; size_t needed; size_t used; va_start(va, format); needed = vsnprintf(&output[0], 0, format.c_str(), va); output.resize(needed + 1); // for null terminator?? used = vsnprintf(&output[0], output.capacity(), format.c_str(), va); // assert(used == needed); va_end(va); return output; } This works, kinda. A few things that I am not sure about are: Do I need to make room for a null terminator, or is this unnecessary? Is capacity() the right function to call here? I keep thinking length() would return 0 since the first character in the string is a '\0'. Occasionally while writing this string's contents to a socket (using its c_str() and length()), I have null bytes popping up on the receiving end, which is causing a bit of grief, but they seem to appear inconsistently. If I don't use this function at all, no null bytes appear.

  • Genetic programming in c++, library suggestions?

    - by shuttle87
    I'm looking to add some genetic algorithms to an Operations research project I have been involved in. Currently we have a program that aids in optimizing some scheduling and we want to add in some heuristics in the form of genetic algorithms. Are there any good libraries for generic genetic programming/algorithms in c++? Or would you recommend I just code my own? I should add that while I am not new to c++ I am fairly new to doing this sort of mathematical optimization work in c++ as the group I worked with previously had tended to use a proprietary optimization package. We have a fitness function that is fairly computationally intensive to evaluate and we have a cluster to run this on so parallelized code is highly desirable. So is c++ a good language for this? If not please recommend some other ones as I am willing to learn another language if it makes life easier. thanks!

  • Basic question on retain/release semantics from Apple's reference library

    - by davetron5000
    I have done Objective-C way back when, and have recently (i.e. just now) read the documentation on Apple's site regarding the use of retain and release. However, there is a bit of code in their Creating an iPhone Application page that has me a bit confused: - (void)setUpPlacardView { // Create the placard view -- it calculates its own frame based on its image. PlacardView *aPlacardView = [[PlacardView alloc] init]; self.placardView = aPlacardView; [aPlacardView release]; // What effect does this have on self.placardView?! placardView.center = self.center; [self addSubview:placardView]; } Not seeing the entire class, it seems that self.placardView is also a PlacardView * and the assignment of it to aPlacardView doesn't seem to indicate it will retain a reference to it. So, it appears to me that the line I've commented ([aPlacardView release];) could result in aPlacardView having a retain count of 0 and thus being deallocated. Since self.placardView points to it, wouldn't that now point at deallocated memory and cause a problem?

  • Selecting an area from displayed image using CImg library

    - by sravan
    hi all, i use CImg for my image processing work. I had written a small piece of code which is follows: #include "../CImg.h" #include <iostream> using namespace std; using namespace cimg_library; int main(int argc,char**argv) { CImg<int> img(argv[1]); CImgDisplay disp; disp.assign(img); while(!disp.is_closed) disp.wait(); return 0; } Now i want to select an area from the displayed image. Can some one tell me how to select an area from displayed image and store the selected pixels, and display the selected region in different display window. If some one can provide code, it will be of great help to me. Thank you all

  • (Cpp) 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! :] Thanks

  • Find out why Xcode has decided to link to a particular library

    - by andygeers
    I'm using the Unity 3D engine to build an iPhone app, and when I go to generate my Xcode project for compilation, it includes a few fairly large libraries: Mono.Security.dll.s, System.dll.s, System.Core.dll.s, etc. I don't know if this question is really an Xcode question or a Unity question, but I'm trying to figure out why each of those libraries is being linked - which functions / classes are being referenced - ideally so that I can rewrite my code to remove as many of the dependencies as possible. Does anybody know a way to find this information out?

  • NET Framework Validation Library

    - by Kane
    As I see it most applications have a requirement for some form of validation and a number of fantastic free offerings are available (I.E., Fluent Validation, Validation Block, Spring, Castle Windsor, etc). My question is why does the .NET Framework not include any inbuilt validation libraries? I am aware the .NET Framework allows a developer the ability to build their own validation libraries/methods/etc. and anything provided as part of the .NET Framework would not always meet everyone’s needs. But surely something could have been included? ASP.NET has a minimal set of validators but these have not really been extended since .NET 2.0 was released.

  • Is there a Javascript library for editing PDFs?

    - by Fletcher Moore
    Based on my Google and stackoverflow search I'm guessing no, but it can't hurt to ask. The goal is: store some blank forms on my server. Then present these to the user, who edits the form in the browser with Javascript and submits the form back to the server. The client wants to reuse parts of an old system (the forms) in which users would download an editable PDF, edit it, and email it back to a secretary. Our users aren't very computer savvy and many don't realize they need to email the forms back, assuming instead the forms somehow get submitted when they save their local changes (or something). I haven't seen the forms yet, so I cannot assess the viability of an alternative.

  • Excel isn't reading sql exported csv properly

    - by mhopkins321
    I have a batch file that calls sqlcmd to run a command and then export the data as a csv. When viewed in a cell the trasancted date for example shows 35:30.0 but if you click on it the formula bar shows 1/1/1900 2:45:00 PM. I need the full timestamp to show in the cell. Any ideas? The batch file is the following sqlcmd -S server -U username -P password -d database -i "D:\path\sqlScript.sql" -s "," > D:\path\report.csv -I -W -k 1 The script is the following. Now I currently have them cast as varchars, but that's simply because i've tried to change it a bit. Varchar doesn't work either. SET NOCOUNT ON; select top(10)BO.Status, cast(tradeDate AS varchar) AS Trade_Date, CAST(closingTime AS varchar) AS Closing_Time, CAST(openingTime AS varchar) AS openingTime FROM GIANT COMPLICATED JOINS OF ALL SORTS OF TABLES
