• How to use LINQ for CRUD with a simple SQL table?

  - by Rob Ferno

  Every LINQ blog I found there seemed around 2 years old, I understand the syntax but need more direction on creating the SQL mapping and context classes. I just need to use LINQ for 2 SQL tables I have, nothing complicated. Do folks write the SQL mapping classes by hand for such cases or is there a decent tool for this? Can someone point me in the right direction?

Can anyone point me to some good tutorials that maybe helped you understand? I'm hoping to "Get it" once and for all. Many many thanks for your help! =]

• HTML5 Offline Storage on iPad and iPhone BUG

  - by scaraveos

  Hello everyone, I created a manifest file with 1000 items. Safari, Mozilla browsers are saving the files offline successfully and even Android saves the files correctly offline. On iPad and iPhone when I am trying to save more than 300 items in some point the applicationCache returns "error". When I am trying to save less (e.x.: 200) it saves the files correctly and the applicationCache returns "cached". Any ideas? Thank you.

(Noob question,I know but it has been irritating me for quite sometime now) -Aby

• Can I set a timeout for a InputStream's read() function?

  - by Zombies

  I have a DataInputStream that I obtained from a Socket. Is there any way I can set a timeout for dis.read(...)? Currently I spawn a new thread to do the read. While the parent thread does a thread.join(timeout) to wait before interrupting it. I am aware of nio, but I don't think I want to refactor that much at this point. Thanks.

• Google Maps API v3 show local businesses/points of interest

  - by julio

  I know at some point I'd come across a Google service built into their API that would provide local information as markers on the viewport (schools, hospitals, etc.)-- I believe this was a simple control that could be added just like the normal map controls, to allow users to turn it on or off with a checkbox or button. I can't seem to find this feature documented anywhere in the v3.0 API docs. Can anyone provide some information on this, or let me know if it was deprecated? Thanks

• initialize a const array in a class initializer in C++

  - by Nathan Fellman

  I have the following class in C++: class a { const int b[2]; // other stuff follows // and here's the constructor a(void); } The question is, how do I initialize b in the initialization list, given that I can't initialize it inside the body of the function of the constructor, because b is const? This doesn't work: a::a(void) : b([2,3]) { // other initialization stuff } Edit: The case in point is when I can have different values for b for different instances, but the values are known to be constant for the lifetime of the instance.
