  • How do I open iPhone camera and restrict to a frame?

    - by Thomas
    Hello All: I'd like to know how to open the camera inside of a pre-defined frame (not the entire screen). When the view loads, I have a box, and inside it, I want to display what the camera sees. I don't want to snap a picture, just basically use the camera as a viewfinder. I have searched this site and have not yet found what I'm looking for. Please help. Thanks! Thomas

  • Divide and conquer method to compute roots [SOLVED]

    - by hellsoul153
    Hello, Knowing that we can use Divide-and-Conquer algorithm to compute large exponents, for exemple 2 exp 100 = 2 exp(50) * 2 exp(50), which is quite more efficient, is this method efficient using roots ? For exemple 2 exp (1/100) = (2 exp(1/50)) exp(1/50) ? In other words, I'm wondering if (n exp(1/x)) is more efficient to (n exp(1/y)) for x < y and where x and y are integers.

  • MSDN about stored procedure default return value

    - by Ilya
    Hello, Could anyone point exactly where MSDN says thet every user stored procedure returns 0 by default if no error happens? In other words, could I be sure that example code given below when being a stored procedure IF someStatement BEGIN RETURN 1 END should always return zero if someStatement is false and no error occurs? I know that it actually works this way, but I failed to find any explicit statement about this from Microsoft.

  • Pylons error handling

    - by TJ Huffington
    Hello, I am just getting started with Pylons and am confused as to how to account for exceptions. What is the proper way to error check user input (ensure a correct email address, check that it doesn't yet exist in the database, etc ...)? Should these checks go inside the model classes or somewhere else? Sample code would be great.

  • Webcam service for a website: user to user, directly, is it possible?

    - by user293224
    Hello everyone I wonder wether on a website like chatroulette for example, the streaming video is going directly from user to user or wether it is going through a server. In other words I wonder wether it is possible to offer a webcam service on a website, so that the streaming video goes directly from user to user, without overloading the system. If it is possible, what technology makes it possible? Flash? Thank you ;)

  • Regex to extract a string between two delimeters WITHOUT also returning the delimeters?

    - by CSharp Noob
    Hello, I want to just extract the text between the brackets -- NOT the brackets, too! My code looks currently like this: var source = "Harley, J. Jesse Dead Game (2009) [Guard]" // Extract role with regex m = Regex.Match(source, @"[(.*)]"); var role = m.Groups[0].Value; // role is now "[Guard]" role = role.Substring(1, role.Length-2); // role is now "Guard" Can you help me to simplify this to just a single regex, instead of the regex, then the substring?

  • Advantages/disadvantages of browser-based interface vs. graphics

    - by Josh
    Hello everyone, I'm in the design phase for a desktop-based application. Because of the nature of this particular application, I believe it would benefit greatly from a web-based approach (i.e., allowing a user to interface with the application through a browser running in kiosk mode) in order to leverage the simplicity of HTML/CSS/JS and the availability of many great JS interface plugins. Does taking this approach (rather than coding in a native or cross-platform graphics library) come with any gotchas?

  • C array assignment and indexing with similar variable.

    - by Todd R.
    Hello! I apologize if this has been posted before. Compiling under two separate compilers, BCC 5.5 and LCC, yields 0 and 1. #include <stdio.h> int main(void) { int i = 0, array[2] = {0, 0}; array[i] = ++i; printf("%d\n", array[1]); } Am I to assume not all compilers evaluate expressions within an array from right to left?
