• Why isnt int pow(int base, int exponent) in the standard C++ libraries?

  - by Dan O

  I feel like I must just be unable to find it. Is there any reason that the c++ pow function does not implement the "power" function for anything except floats and doubles? I know the implementation is trivial, I just feel like I'm doing work that should be in a standard library. A robust power function (ie handles overflow in some consistent, explicit way) is not fun to write.

• What's the difference between Render and RenderControl in WebControl creation?

  - by Michael Itzoe

  I've recently learned to write my own WebControls, but I'm still hazy on the difference between Render and RenderControl. I started out using Render, but at some point I started using RenderControl, which I now use exclusively. If I'm forming a bad habit I'd like to nip it in the bud now before I get set in my ways.

• Tools to update tables in SQL server 2000/2005

  - by Stan

  Is there any handy tool that can make updating tables easier? Usually I got an Excel file with the original value in one column and new value in another column. Then I write a formula in Excel to create the 'update' statement. Is there any way to simplify the updating task? I believe the approach in SQL server 2000 and 2005 would be different, so could we discuss them both? Thanks.

  I am trying to write a pre-qualification programming exam, hopefully using Google Forms... however they seem to be unable to do new-lines in both the questions and the section headers... My current format is new page for each question, with a "section header" as the main question (because it has a textarea for the "code snippet") and a "multiple choice question" as the ummm... question answer... Help much appreciated...

• Remove leading zero's from alphanumeic text

  - by cedar715

  I've seen questions to prefix zeros here in SO. But not the other way !! Can you guys suggest me how to remove the leading zeros in alphanumeric text. Are there any built-in APIs or do I need to write a method to trim the leading zero's? Example: 01234 converts to 1234 0001234a converts to 1234a 001234-a converts to 1234-a 101234 remains as 101234 2509398 remains as 2509398 123z remains as 123z 000002829839 converts to 2829839

• Is using project:permissions in a symfony project safe in a production environment?

  - by mhughes

  As the question states, is this task safe for a production environment? I find the permissions rather permissive, the cache directory is the one i find particularly suspicious. Write and execution permission on a code directory is somewhat suspicious. Cheers

• Is there way to determine if a file has been executed or not in C#?

  - by Shane

  I'm looking for a way to determine if a file has been executed or not. I've looked a bit into FileInfo's LastAccessTime but this doesn't seem to change when a file is executed. I've also looked into FileSystemWatcher but this also doesn't seem to offer a solution. Is there such a thing as a file execution listener or is there another way? If it helps, i'm looking to write a folder listener that renames an .avi file within it after it has been watched/executed.

• Conditional Join In LINQ?

  - by Soo

  I am trying to write a query that grabs information from one database and joins it to information in a different database. TableA idA valueA idB TableB idB valueB The tricky part is that in TableA, idB isn't always defined, so when I do a normal join, I only get results where TableA has a idB value. What I want is to be able to grab all of the information from TableA even if it doesn't have a corresponding idB value.

  Several questions: How do I get my C# WCF service to use Protocol Buffers? How do I write a C++ client for a WCF service? How do I get that C++ client to use Protocol Buffers when talking to the WCF service.

• Why is "int + string" possible in statically-typed C# but not in dynamically-typed Python?

  - by Salvador Dali

  While studying C# I found it really strange, that dynamically typed Python will rise an error in the following code: i = 5 print i + " " whereas statically typed C# will normally proceed the similar code: int i = 5; Console.Write(i + " "); I would expect other way around (in python I would be able to do this without any casting, but C# would require me to cast int to string or string to int). Just to highlight, I am not asking what language is better, I am curious what was the reason behind implementing the language this way.
