• How to subtract dates in YYYYMMDD format?

  - by NinjaBomb

  I have 2 integer fields that represent dates in the YYYYMMDD format. What is the best way to subtract 2 of these fields to get the correct # of days between them? For instance, if I take the difference between 20100511 and 20100428 I would like the result to be 13 and not 83. I know I need to convert the integer fields into date formats but everything I have tried either throws an exception or doesn't work correctly. What am I missing? Answers in vb.net please

• Creating Synch Point In TFS Source Tree Development Cycle

  - by Rob G

  Our development cycle rarely requires a branch so we have what tfs appears to consider a single, never-ending development cycle. Our problem is that each build includes an ever increasing long "Generating list of changesets and updating work items" step that includes all changesets/work items back to day 1. What is the proper step that we need to perform to formally lock and label (wrong terms I'm sure) the source tree so that a new cycle of changesets and work items can begin. Thanks!

• Is it possible to create a FIPS 140-2 compliant server in Perl?

  - by Nayruden

  The question is pretty simple, is it possible to create a FIPS 140-2 compliant server in Perl? Especially, is it possible without modifying any of the C code for the modules? If it's not possible in straight Perl, what would be the easiest way to go about it from a C perspective? I'm basically creating a mini-httpd that only serves up a single file, but due to security restrictions it needs to be served up on SSL under FIPS compliance.

• Stateless singleton VS Static methods

  - by Sebastien Lorber

  Hey, Don't find any good answer to this simple question about helper/utils classes: Why would i create a singleton (stateless) rather than static methods? Why an object instance could be needed while the object has no state? Sometimes i really don't know what to use...

• Why does every third party control set rewrite the basics of ASP.Net?

  - by Earlz

  Of the control sets I've seen for ASP.Net they all exhibit a strange property. They rewrite everything in the ASP.Net control set. For instance both DevExpress and Telerik have their own Panel, Label, and UpdatePanel controls among others. Why do vendors do this? Is it just to create a form of lock in or is it actually necessary?

• Shopping Cart with multiple orders in ASP

  - by Joao Heleno

  I'm building an e-commerce website in ASP.Net/C# and I'm having some difficulties with my shopping cart... I want my costumers to be able to say "I want X boxes, and each box carries Y items". Let's say, for instance, my website sells flowers. A client logs in and then chooses X bouquets and then for each bouquet he adds flowers from the catalog. Can you point me out some links or tips in order to achieve this behaviour? Thanks

• Tomcat Load Balalncing - Programatic Parameter Based ??

  - by Gala101

  Here's the scenario: Many users access an application (running on tomcat), the user's data is segmented into multiple databases, say each db containing 1000 user's data. Now is it somehow possible to have 100s of tomcat servers running on 'inexpensive' PC class machines with each connecting to a single db, with user's session getting passed to appropriate tomcat and becoming 'Sticky' there. Can have some sort of 'gateway' deciding which user goes where and doing the load-balancing appropriately. Would make a great scalability solution :)

• Can I enable/diable groups of breakpoints in C++ Builder?

  - by mawg

  The title says it all. One specific instance, I want to set a BP on every switch(msg) handled in WndProc() - but not until my app has initialized and is 'stable'. Of course, it receives a lot of windows messages when it starts up. I can't see a way to toggle a group of breakpoints, or to save them for later, use other BPs then restore the first set.

• Validate HTML entities in JavaScript

  - by Eduard Luca

  I have a small JavaScript validation script that validates inputs based on Regex. I want to allow certain characters that are not exactly common (not sure if they're UTF8). For example I want to allow the following character ’, which looks like a single quote, but isn't. I got the HTML code for this which is &#8217;, but I'm not sure how to put this into the Regex. I've tried just inputting [&#8217]* but it doesn't validate.

• Merging .NET assemblies on Windows Store / Phone 8 / Portable Class Library

  - by Gabriel S.

  Is there a way to embed multiple dependent assemblies into a single one for projects written on the following platform types: Windows Store Apps, Windows Phone 8, Portable Class Library? I know that for regular .Net projects there is ILMerge, but on the aforementioned project types it doesn't work. Embedding assemblies as resources and then manually resolving the references using AppDomain.CurrentDomain.AssemblyResolve is not possible either, since AppDomain is not available in these types of project.

• Can the same DLL data be shared by 2 different processes ?

  - by Jelly Amma

  I have two different C# applications that are running at the same time. I would like both of them to be able to access the same "instance" of a DLL (also in C#). The DLL holds some data that I'd like to return to whichever of the two applications is asking for it. My DLL is thread-safe so I was hoping this would be possible but I'm not sure how. Any help or advice would be much appreciated.

• arbitrary input from stdin to shell

  - by python_noob

  So I have this existing command that accepts a single argument, but I need something that accepts the argument over stdin instead. A shell script wrapper like the following works, but as I will be allowing untrusted users to pass arbitrary strings on stdin, I'm wondering if there's potential for someone to execute arbitary commands on the shell. #!/bin/sh $CMD "`cat`" Obviously if $CMD has a vulnerability in the way it processes the argument there's nothing I can do, so I'm concerned stuff like this: Somehow allow the user to escape the double quotes and pass input into argument #2 of $CMD Somehow cause another arbitary command to run
