  • Choosing between assembler and COBOL

    - by Azares Cob
    I have to rewrite and greatly modify parts of a legacy COBOL application. The COBOL source-code is available (around 100.000 lines of copy & pasted code mixed with GOTOs). Some more details on the system: It is a general management system controlling transactions, bank management, customer data and employees of the company I work for. The COBOL-powered database is about 4 Terabytes distributed over 50 old HDDs. (But messing around with them is the sysadmins job) They are using COBOL85 only. Now I have two options: Rewrite and refactor 50% of the old COBOL system, or use X86 assembly. Should I use X86 assembler or COBOL?

  • Visual Studio - How to use an existing vsproj's project settings as a template for new project?

    - by Jakobud
    There is some software I want to write a plugin for. The software includes some sample plugins. I want to create a new fresh project but I want to use one of the sample plugin vsproj's project settings as a template. It doesn't seem very clear on how to do this. If I do "New Project From Existing Code" that only imports the cpp, h, etc files into the new project. Right now the only way I can see to copy a sample projects settings is to open two instances of VS2005 next to each other and simply mimic the settings... Surely there is a built in method of doing this?

  • Matching a rotated bitmap to a collage image

    - by Dmi
    Hi, My problem is that I have an image of a detailed street map. On this map, there can be a certain small image of a sign (such as a traffic light icon) rotated at any angle, maybe resized. I have this small image in a bitmap. Is there any algorithm or technique by which I can locate this bitmap if a copy of it exists, rotated and maybe resized, in the large collage image? This is similar to the problem with Augmented Reality and locating the marker image, but mine is only 2D with no perspective distortion.

  • Storage drives is causting system crash

    - by Chad
    I'm running Centos 5.4 with 750GB(ntfs) and 2TB drives for storage. Originally I installed the 750, everything seemed fine and then I installed the 2TB drive with NTFS already partitioned. I noticed when I would copy a lot of videos it would crash (no mouse or response from server) about 20min into it. After doing some troubleshooting I noticed the 750 would also crash when doing the same task so I decided that NTFS may be the problem. I unmounted the 2TB drive and tried to partition and format it using ext2 but when using parted it would crash at this point "writing inode tables". Looking at the dmesg logs I believe this is the error "mtrr: type mismatch for e0000000,10000000 old: write-back new: write-combining". Any idea as to what could be causing this?

  • Hashbytes comparison in stored proceduring not matching record

    - by Michael Itzoe
    The password field in my user table (SQL Server 2008) is encrypted using HASHBYTES on insertion. I have a stored procedure with parameters for the username and plain-text password which does a SELECT using that username and the password sent through HASHBYTES, then returns the user record if it finds a match. The SP is always returning an empty recordset, but if I copy and paste just the SELECT from the SP to a new query window, it returns the matched record. There're no other statements in the SP. I'm missing something here; what is it?

  • Why pass by const reference instead of by value?

    - by Maulrus
    From what I understand: when you pass by value, the function makes a local copy of the passed argument and uses that; when the function ends, it goes out of scope. When you pass by const reference, the function uses a reference to the passed argument that can't be modified. I don't understand, however, why one would choose one over the other, except in a situation where an argument needs to be modified and returned. If you had a void function where nothing is getting returned, why choose one over the other?

  • How do you make your Java application memory efficient?

    - by Boune
    How do you optimize the heap size usage of an application that has a lot (millions) of long-lived objects? (big cache, loading lots of records from a db) Use the right data type Avoid java.lang.String to represent other data types Avoid duplicated objects Use enums if the values are known in advance Use object pools String.intern() (good idea?) Load/keep only the objects you need I am looking for general programming or Java specific answers. No funky compiler switch. Edit: Optimize the memory representation of a POJO that can appear millions of times in the heap. Use cases Load a huge csv file in memory (converted into POJOs) Use hibernate to retrieve million of records from a database Resume of answers: Use flyweight pattern Copy on write Instead of loading 10M objects with 3 properties, is it more efficient to have 3 arrays (or other data structure) of size 10M? (Could be a pain to manipulate data but if you are really short on memory...)

  • Copying blocks (ie: copying them to instance variables) in Objective-C

    - by RyanWilcox
    I'm trying to understand blocks. I get how to use them normally, when passed directly to a method. I'm interested now in taking a block, storing it (say) in an instance variable and calling it later. The blocks programming guide makes it sound like I can do this, by using Block_copy / retain to copy the block away, but when I try to run it I crash my program. - (void) setupStoredBlock { int salt = 42; m_storedBlock = ^(int incoming){ return 2 + incoming + salt; }; [m_storedBlock retain]; } I try to call it later: - (void) runStoredBlock { int outputValue = m_storedBlock(5); NSLog(@"When we ran our stored blockwe got back: %d", outputValue); [m_storedBlock release]; } Anyone have any insights? (Or, is there something I'm not getting with blocks?) Thank you very much!

  • Suggestions for a C++ IDE?

    - by AedonEtLIRA
    I know this is is a shifty question and really isn't easy to answer, but bare with me. For a while now I have been using Eclipse and doing Java programming. Now that I reach a point where I'm comfortable in Java, I wish to move on back into C++ and actually make something more than a single class that prints to terminal; and work in OpenGL :). So I wonder if anybody has a recomendation of IDE's that resemble or are as fluid as Eclipse? I am aware that Eclipse has a C++ plugin, but it really doesn't feel user friendly (at least to a pampered java programmer!). I have (I think I still have it?) a copy of Visual Studio 2005, but want to see if anyone has any better ideas. Thanks ~Aedon

  • FileSystemWatcher surpassing Active Directory restrictions

    - by DevexPP
    While experimenting with FileSystemWatcher, I've found out that it somehow surpasses Active Directory's restrictions to files and folders, and will raise change events with information about what has changed in files and folders that you don't even have access to. I have two questions about that: 1) Why does this happen ? 2) Is this a problem in the AD configuration ? how do I fix it ? 3) Is there any way to gather these files, or even create a FileSystemInfo of them to get more info about the files (not only the changes made on them) ? As far as I've tried, only the FileSystemWatcher immune to the restrictions, I can't run any other thing over it, here's a list of what I've tried: File.Exists Directory.Exists FileInfo instance on found files DirectoryInfo instance on found files File.Copy File.Delete

  • Is it possible to disable the iPhone's automatic hyperlinks?

    - by mririgo
    We send out a notification email whenever we have "phishing" emails reported to us. In these emails, we include a copy-paste of the text inside the original phishing email as a sample of what is reported to us. Our code strips all hyperlinks out of the email via PHP, but still includes (in plain text) the link. When users receive this email in their client (Thunderbird, Outlook, Horde/IMP, etc), the hyperlink is removed. However, the iPhone likes to take web addresses in plain text and automatically turn them into hyperlinks. Is there any possible way to stop this action from happening via a HTML tag or by using PHP to replace certain parts of the hyperlink?

  • Problem with running a program from flashdrive

    - by rajivpradeep
    I have a USB drive with two partitions in it, one hidden and one normal. I have an application which swaps the memory and runs the flash application in hidden zone. The problem is that the application works fine on Windows 7 and when run on Win XP, it swaps the partitions but doesn't run the flash applications but just keeps running in the background. I can see it in task manager. But, when I copy the application to desktop and run, it runs with no glitch. I was facing the same problem on Win 7 too, but it was running as required when I ran it using "Run in XP mode" and then I applied a SHIM and is running since then as required. The application is built using VC++ 2008. does anyone know the solution?

  • Another passing variable through function jQuery/JS problem...

    - by dallen
    Here's my code: function mouseOver(variable) { return function() { $(variable).fadeIn(100); }; } function mouseOut(variable) { return function() { $(variable).fadeOut(100); }; } function lawyer(var1, var2, var3, var4) { return function() { $(var1).bind('mouseenter', mouseOver(var2)).bind('mouseleave', mouseOut(var2)).click( function() { $(var1).unbind('mouseenter').unbind('mouseleave'); $(var1).removeClass('off').addClass('on'); $(var3).bind('mouseenter', mouseOver(var4)).bind('mouseleave', mouseOut(var4)); $(var3).removeClass('on').addClass('off'); $(var4).hide(); }); } } lawyer("#group", ".b", "#group2", ".l"); What would be the reason for this not working? It works in that it hides $(var4).hide();, but clicking on the object doesn't seem to do anything. It works if I take the code out of a function and just copy/paste it a few times and change the targets. I'm not seeing it... Any help would be appreciated!

  • Static member object of a class in the same class

    - by Luv
    Suppose we have a class as class Egg { static Egg e; int i; Egg(int ii):i(ii) {} Egg(const Egg &); //Prevents copy-constructor to be called public: static Egg* instance() {return &e} }; Egg Egg::e(47); This code guarantees that we cannot create any object, but could use only the static object. But how could we declare static object of the same class in the class. And also one thing more since e is a static object, and static objects can call only static member functions, so how could the constructor been called here for static object e, also its constructors are private.

  • Generate a collection of changed lines between two revisions of a file using Java

    - by mchr
    I am writing an eclipse plugin which needs to be able to determine which lines of a file have changed compared to a different version of the same file. Is there an existing class or library which I can use for this task? The closest I have found is org.eclipse.compare.internal.merge.DocumentMerger. This can be used to find the information I need but is in an internal package so is not suitable for me to use. I could copy/paste the source of this class and adapt it to my requirements. However, I am hoping there is an existing library to handle textual comparisons.

  • Missing System.Core.dll and others on Visual Studio 2010 Project targeting 3.5 Framework

    - by Mark Struzinski
    I just got Visual Studio 2010 installed and running on my development machine (alongside VS 2008). The first thing I did was make a copy of an existing project and convert it up to the VS 2010 project. I told the conversion wizard to leave the project targeting the 3.5 framework. The project compiles and runs just fine in VS 2008. When I go to build it, several of my references are marked as missing (System.Core, System.Xml.Linq, System.Data.DataSetExtensions). When I go to the Add Reference dialog, they are not present. Yet if I view the GAC at C:\Windows\Assembly, I can see the entries there. I have tried converting the projects to 4.0, then back down to 3.5, and also unloading/reloading the projects. Nothing works. Has anyone else ran across this problem?

  • gvim: Easy copying into system clipboard

    - by Georg Jaehnig
    I am using gVim on Ubuntu 10.10. I want to copy (yank) text to the system clipboard, so that the copied text is available in other applications. This works with "+y. But I want to have it working with y. I have tried to map y to "+y but then yy doesn't work anymore (since it produces "+y"+y). I have also tried :set clipboard=unnamed but this works only the other direction: Text in the system clipboard I can paste with p.

  • Operator Overloading for Queue C++

    - by Josh
    I was trying to use the overload operator method to copy the entries of one queue into another, but I am going wrong with my function. I don't know how else to access the values of the queue "original" any other way than what I have below: struct Node { int item; Node* next; }; class Queue { public: [...] //Extra code here void operator = (const Queue &original); protected: Node *front, *end; } void Queue::operator=(const Queue &original) { //THIS IS WHERE IM GOING WRONG while(original.front->next != NULL) { front->item = original.front->item; front->next = new Node; front = front->next; original.front = original.front->next; } }

  • Subversion post-commit hook

    - by GeoSQL
    I am trying to get SVN to copy files to my htdocs folder on commit. Here is what I have so far in my post-commit.bat: "C:\subversion\bin\svn.exe" update "C:\apache\apache2.2\htdocs" When I look at the log files created by the hook I get the following line: Skipped 'C:\Apache\Apache2.2\htdocs' Does anyone know why this is happening? No matter what directory I choose as a destination, I get the same error. I am running SVN 1.6.4, Tortoise 1.6.8, Apache 2.2, WinXP SP3 I am not using username and password because there is no security set up on the SVN repository. It's just me developing. Thanks

  • How do I gain permissions to a Sql Compact Database?

    - by Quenton Jones
    I have an Sql Compact Database v3.5 that I'm bundling with my application. When the application is installed, the database is copied into the application's Program Files directory. Because of Vista and Win7's security settings, the installed application can't access the database file. It is merely a problem of having the database file reside in the Program Files. The solution I have thought of is to copy the file into Program Data, but does anyone have another solution? I am sure others have come across a similar problem. Thanks in advance for your input.

  • Upload image with Tumblr API in PHP

    - by John
    I'm having trouble uploading a photo from my computer to tumblr using their API. http://www.tumblr.com/docs/en/api photo - Requires either source or data, but not both. If both are specified, source is used. * source - The URL of the photo to copy. This must be a web-accessible URL, not a local file or intranet location. * data - An image file. See File uploads below. * caption (optional, HTML allowed) * click-through-url (optional) I need to use data File uploads can be done in a data parameter where specified above. You may use either of the common encoding methods: multipart/form-data method, like a file upload box in a web form. Maximum size: o 50 MB for videos o 10 MB for photos o 10 MB for audio I would post my code but it's not showing up correctly for me.
