  • 64-bit integers in Cython

    - by Homayoon
    I'm trying to interface a C++ library (pHash) with Python using Cython, but I have trouble with some of the types. The library functions use "unsigned long long" and I can't find a way to declare variables and parameters with this type. I searched for a list of the types that I can use with cdef but I found nothing. Can anyone point me to such a list (if it exists) or otherwise suggest a way to use 64 bit types in Cython? Thanks.

  • ASP.NET Hosting and routing

    - by V-Man
    Is it possible to host 2 asp.net projects off one ip address? I don't have a domain name just an ip number. I'm running IIS7. The first project runs and displays fine over the web by simply typing in the ip address into the browser but I'm having trouble accessing the second. Currently both projects have virtual directories in IIS7. Help is greatly appreciated. Thx

  • Why does Mercurial only have one level of rollback?

    - by Nick Pierpoint
    I understand the restrictions of rollback and the care required in its use (for example, http://www.selenic.com/mercurial/hg.1.html#rollback), but I just wondered why there is only 1 level of rollback. My guess it's a design decision and that the hassle of storing multiple previous transactional states to handle multiple levels of rollback is more trouble than its worth.

  • How do I get all the calendar entries for a particular time range using Google Calendar API

    - by BeWarned
    I want to view events over specific time range for a specific calendar, but am having trouble using the API, It is a generic API, and it reminds me of using the DOM. The problem is that it seems difficult to work with because much of the information is in generic base classes. How do I get the events for a calendar using Groovy or Java? Does anybody have an example of passing credentials using curl? Example code would be appreciated.

  • Secure automated SSH/SFTP after reboot

    - by mozillalives
    I need to give a daemon ssh access to a particular server. Currently I have it setup to use ssh keys and a keychain, but the trouble with this method is if a reboot occurs. Unless I'm missing something, I would need to login after a system reboot and add the key to the keychain. Is there a way I could avoid/automate this? I'm considering using expect if I can't find any other way.

  • void foo(int &x) -> Ruby? Passing integers by reference?

    - by Earlz
    Hello, as a way to spice up my C++ programming homework, I've decided to instead of typing the C++ from the book onto my computer, instead reforming it in Ruby. Yes it's a bit silly, but I'm bored. Anyway, I'm having trouble converting this kind of function to Ruby void swap(int &a,int &b){ int c=b; b=a; a=c } What would the equivalent ruby code looking inside a function ?

  • What's the simplest way to make a scrollable list of controls with labels?

    - by Jon Cage
    Using C++/CLI and Windows Forms, I'm trying to make a simple scrollable list of labelled text controls as a way of displaying some data fields. I'm having trouble making a TableLayoutPanel scrollable - every combination of properties I've tried seems to result in some really peculiar side effects. So I have two questions: Is this the best way to do it. If it is a reasonable approach, what magic combination of settings should I apply to the table layout panel to make it play ball?

  • How do I stop cropping of a transformed (scaled) image in a grid (silverlight)

    - by Jeremy
    I have a grid with an image in it. Initially, the image is larger than the grid, so it gets cropped which is fine, but if I apply a scaling transform to causing the image to shrink, the portion that was initally cropped remains cropped, but I want it displayed now, because it would fit in the grid. I concidered putting my image in a canvas, but I want it centered vertically and horizontally, which is giving me trouble, so I switched to a grid.

  • Outlook Contact Export to CSV format differences

    - by Jeffsline
    Outlook 2003 and Outlook 2007 allow you to export your contacts to CSV format. Is there a difference between the two or is this in fact the same format; in other words, are they backward compatible or did Outlook 2007 create some new fields that Outlook 2003 would have trouble importing?

  • How do I access the enumerated item with an indexer and assign array string to it for display?

    - by g00p3k
    EDITED: Updated 3/23/09. See rest of post at bottom. I'm still having trouble with the indexer. Anymore help or examples would really help me out. Write a class, MyCourses, that contains an enumeration of all the courses that you are currently taking. This enum should be nested inside of your class MyCourses. Your class should also have an array field that provides a short description (as a String) of each of your courses. Write an indexer that takes one of your enumerated courses as an index and returns the String description of the course. Write a class MyFriends that contains an indexer that provides access to the names of your friends. namespace IT274_Unit4Project { public class MyCourses { // enumeration that contains an enumeration of all the courses that // student is currently enrolled in public enum CourseName {IT274= 0,CS210 = 1} // array field that provides short description for each of classes, // returns string description of the course private String[] courseDescription = {"Intermediate C#: Teaches intermediate elements of C# programming and software design", "Career Development Strategies: Teaches principles for career progression, resume preparation, and overall self anaylsis"}; // indexer that takes one of the enumerated courses as an index // and returns the String description of the course public String this[CourseName index] { get { if (index == 1) return courseDescription[0]; else return courseDescription[1]; } set { if (index == 1) courseDescription[0] = value; else courseDescription[1] = value; } } } }//end public class MyCourses I'm working on this homework project and having trouble understanding the text explaining how to correctly take the accessed value of the enumeration and then apply the string array value to it. Can you please help me understand this? The text we are using is very difficult and poorly written for a beginner to understand, so I'm kind of on my own here. I've got the first parts written, but need some help on the accessing of the enumeration value and assigning, i think i'm close, but don't understand how to properly get and set the values on this. Please do not provide me with direct code answers, unless a MSDN style explanation that is generalized and not specific to my project. ie: public class MyClass { string field1; string field2; //properties public string Value1 get etc... Thanks!

  • Using build with a has_one association in rails.

    - by espinet
    This is a really noob question but im having trouble finding the answer, is there a way in rails to have 0 or 1 association? For example, I create a user with no objects, than later on create an object for that user. I tried using build with a 'has_one' association but that blew up... The only way I see this working is using 'has_many'. The user is suppose to only have at most one of these objects, is there any way to do this?

  • How to move value from the stack to ST(0)?

    - by George Edison
    I am having trouble believing the following code is the most efficient way to move a value from the stack to ST(0): .data var dd 4.2 tmp dd ? .code mov EAX, var push EAX ; top of stack now contains a value ; move it to ST(0) pop EAX mov tmp, EAX fld tmp Is the temporary variable really necessary? Further, is there an easier way to get a value from the stack to ST(0)?
