• Framework for adding users/groups/permissions functionality to an application (possibly integrating

  - by vfilby

  I am looking to see if there is a good library or framework that I can use to simplify adding user/group/permission management to a .Net application (4.0 VS2010). If the framework can work on it's own or integrate with Active Directory that would be a huge bonus. So far I have found Visual Guard, if you have any experience using Visual Guard to provide user/group/permission functionality I definitely want to hear your feedback on how you liked working with it, pitfalls and benefits

  - by jcyang

  According to this page,it seems that Perl,PHP,Python is 50 times slower than C/C++/Java. Thus,I think Perl,PHP,Python could not handle critical application(such as 100 million user,xx million request every second) well.But exceptions are exist,e.g. facebook(it is said facebook is written with PHP entirely),wikipeida.Moreover,I heard google use Python extensively. So why?Is it the faster hardware fill the big speed gap between C/C++/Java and Perl/PHP/Python? thanks.

• Iframe Facebook application and cookies [Internet Explorer]

  - by Joe P

  I have downloaded the IBM P3P editor, created files and uploaded them to my server. And cookies are still not recognized in Internet Explorer. I've checked the P3P validation tool and it seems to validate. The application can be viewed here: apps.facebook.com/naplesnews and the iframe points to www.naplesnews.com/facebook/app/. Again www.naplesnews.com/facebook/app/ seems to validate with no issues as well. Any idea what I'm missing here?

• Including FFMPEG with a Java application on Mac

  - by James Skidmore

  I'm writing a Java program that will be used on both Windows and Mac. In the program, I'm using FFMPEG to convert a MOV file to an FLV. On Windows, it's no problem -- simply call the command. But on Mac, I'm not quite sure what to do. Does the user really have to install FFMPEG on their machine, or can it somehow be included in the Java application? Thanks for any help/guidance!

• Qwt setAxisScale() seems to lock up application when given numbers with greater precision than 2e-07

  - by Dane Larsen

  I'm using Qwt for some scientific graphing, and I'm working with some fairly small numbers, the smallest being around 1.0e-22. I'm trying to call setAxisScale(xaxis, xmin, xmax) //xmin = 0, xmax = 2.0e-10 But when I do, the application locks up. I haven't found anything in the documentation that refers to a minimum value. Xmin and xmax are both doubles, so that shouldn't be a problem. Is this a bug in Qwt, or am I doing something wrong? Thanks in advance

• Including SQL Server Express with Application

  - by Echilon

  I'm bundling an application for distribution and SQL Server is a prequisite so we're including SQL Server Express. What's the easiest way to include SQL server in a point and click installer? In the past I've used NSIS, but it was always flaky when installing the .NET Framework, so .NET, SQL Server and our app seems like an impossible task. It needs to be free, which probably cuts back my options a tad. Any suggestions or recommendations?
