• linking the EF 4.0 context to the WCF call context

Any idea how is the best way for implement this?

• Why can’t GridView extract child control’s values directly?

  - by SourceC

  Hello using Bind in a GridView control template enables the control to extract values from child controls in the template and pass them to the data source control. The data source control in turn performs the appropriate command for the database. For this reason, the Bind function is used inside the EditItemTemplate or InsertItemTemplate of a data-bound control. Why is Bind() needed to extract values and pass them to GridView. Why isn’t GridView able to extract child control’s values directly? thanx

• PHP bitwise left shifting 32 spaces problem and bad results with large numbers arithmetic operations

  - by Victor Stanciu

  Hello, I have the following problems: First: I am trying to do a 32-spaces bitwise left shift on a large number, and for some reason the number is always returned as-is. For example: echo(516103988<<32); // echoes 516103988 Because shifting the bits to the left one space is the equivalent of multiplying by 2, i tried multiplying the number by 2^32, and it works, it returns 2216649749795176448. Second: I have to add 9379 to the number from the above point: printf('%0.0f', 2216649749795176448 + 9379); // prints 2216649749795185920 Should print: 2216649749795185827

• Clarification on recaptcha

  - by luckytaxi

  Um so I was in for a little bit of a surprise tonight. I spent a good 20 mins trying to figure out why I was able to submit a form knowing that what I entered into the recaptcha field was invalid. Is it true that you don't need to input the exact words it displays? If it shows me two words and I misspelled one of the words, I still pass validation? Same goes if "hello world" and I input "hell man" it still works.
