  • iphone facebook framework

    - by satyam
    i'm able to successfully integrate facebook into my iphone application. but just before publishing, it will show a dialog which is an instance of "FBStreamDialog". I'm only setting "userMessagePrompt" which is "Share the app with Facebook and follow the link to obtain the app" and "attachment" with "Share the app". When the app is run and when FBStreamDialog is shown, I'm seeing only "attachment" and not "userMessagePrompt". Why?

  • Creating a Desktop Shortcut Using a Web Page

    - by cmessier
    I am trying to create something on a webpage that allows my users to create a desktop shortcut. Because my users are NOT technically savvy, I would like to avoid having them try to drag and drop. Is there a way that I could create a button on a webpage (either using JavaScript or .Net) that automatically creates a desktop shortcut for the user? If you have follow up questions, please let me know. Thanks

  • List files recursively in linux with path relative to the current directory

    - by Darryl Hein
    This is similar to this question, but I want to include the path relative to the current directory in unix. If can do the following: ls -LR | grep .txt But it doesn't include the full paths. For example, I have the follow dir structure: test1/file.txt test2/file1.txt test2/file2.txt The code above will return: file.txt file1.txt file2.txt How can I get it to include the paths relative to the current directory using standard nix commands?

  • Consistency vs Design Guidelines

    - by Adrian Faciu
    Lets say that you get involved in the development of a large project that is already in development for a long period ( more than one year ). The projects follows some of the current design guidelines, but also has a few different, that are currently discouraged ( mostly at naming guidelines ). Supposing that you can't/aren't allowed to change the whole project: What should be more important, consistency, follow the existing ones and defy current guidelines or the usage of the guidelines, creating differences between modules of the same project ? Thanks.

  • Can I create an ASP.NET MVC 2 project with multiple areas without referencing each Child in the pare

    - by No Refunds No Returns
    This is a follow-up question to my original query: http://stackoverflow.com/questions/1791605/how-can-i-use-multiple-projects-to-separate-a-large-asp-net-mvc-site-into-departm Now that I have this working, is there a way to still have multiple project but not have to reference each child area from the parent project? Ideally I'd like to be able to have multiple, separate and distinct projects that only come together on the production/test machines. I should be able to build and test each "area" separately.

  • Designing a database file format

    - by RoliSoft
    I would like to design my own database engine for educational purposes, for the time being. Designing a binary file format is not hard nor the question, I've done it in the past, but while designing a database file format, I have come across a very important question: How to handle the deletion of an item? So far, I've thought of the following two options: Each item will have a "deleted" bit which is set to 1 upon deletion. Pro: relatively fast. Con: potentially sensitive data will remain in the file. 0x00 out the whole item upon deletion. Pro: potentially sensitive data will be removed from the file. Con: relatively slow. Recreating the whole database. Pro: no empty blocks which makes the follow-up question void. Con: it's a really good idea to overwrite the whole 4 GB database file because a user corrected a typo. I will sell this method to Twitter ASAP! Now let's say you already have a few empty blocks in your database (deleted items). The follow-up question is how to handle the insertion of a new item? Append the item to the end of the file. Pro: fastest possible. Con: file will get huge because of all the empty blocks that remain because deleted items aren't actually deleted. Search for an empty block exactly the size of the one you're inserting. Pro: may get rid of some blocks. Con: you may end up scanning the whole file at each insert only to find out it's very unlikely to come across a perfectly fitting empty block. Find the first empty block which is equal or larger than the item you're inserting. Pro: you probably won't end up scanning the whole file, as you will find an empty block somewhere mid-way; this will keep the file size relatively low. Con: there will still be lots of leftover 0x00 bytes at the end of items which were inserted into bigger empty blocks than they are. Rigth now, I think the first deletion method and the last insertion method are probably the "best" mix, but they would still have their own small issues. Alternatively, the first insertion method and scheduled full database recreation. (Probably not a good idea when working with really large databases. Also, each small update in that method will clone the whole item to the end of the file, thus accelerating file growth at a potentially insane rate.) Unless there is a way of deleting/inserting blocks from/to the middle of the file in a file-system approved way, what's the best way to do this? More importantly, how do databases currently used in production usually handle this?

  • When should I use temporary variables?

    - by Kyle
    Specifically, I'm wondering which of these I should write: shared_ptr<GuiContextMenu> subMenu = items[j].subMenu.lock(); if (subMenu) subMenu->setVisible(false); or: if (items[j].subMenu.lock() items[j].subMenu.lock()->setVisible(false); I am not required to follow any style guidelines. After optimization, I don't think either choice makes a difference in performance. What is generally the preferred style and why?

    I have free-rein over what I do on a final assignment for school, with respect to modifying a simple direct-x game that currently just has the camera follow some rollercoaster rails.

  • Is PyOpenGL a good place to start learning opengl programing?

    - by Isaiah
    I want to start learning OpenGL but I don't really want to have to learn another language to do it. I already am pretty proficient in python and enjoy the language. I just want to know how close it is to the regular api? Will I be able to pretty easily follow tutorials and books without too much trouble? I know C++ gives better performance, but for just learning can I go wrong with PyOpenGL? Thanks alot
