• What are the rules about using an underscore in a C++ identifier?

  - by Roger Lipscombe

  It's common in C++ to name member variables with some kind of prefix to denote the fact that they're member variables, rather than local variables or parameters. If you've come from an MFC background, you'll probably use "m_foo". I've also seen "myFoo" occasionally. C# (or possibly just .NET) seems to recommend using just an underscore, as in "_foo". Is this allowed by the C++ standard?

• How do I diagnose a failure in the Membership service on an ASP.NET remote site?

  - by ProfK

  Yesterday I added a custom MembershipProvider to an ASP.NET web application, but when I deployed the application to its remote host server, it failed. I know I had the login info correct, and I also know that for nearly any exception in the login process, the Login control displays the standard error message, "Your login failed", so I assume something is wrong in the code/config. What can I do to diagnose what is wrong on the server?

• Correct way to create a menu with shortcuts in WPF

  - by mattdekrey

  What is the correct/best way to create a menu with hotkey shortcuts? I simply want a File menu like Visual Studio's that has New, Open, Save, Save All, Exit, and a few other standard shortcuts. It seems that InputGestureText displays the appropriate text, but since it's called "Text" and doesn't seem to trigger events, I'm going to assume that isn't the right way to do it. The Command architecture also seems fairly bulky, so I don't want to head down that path if there is a better way.

• What business implications are there working with a foreign consultant?

  - by Chris Marisic

  For a US business does anything occur differently for employing a foreign consultant as a opposed to a standard 1099 consultant that is a legal resident? There would be no relocation of the consultant so I believe that would rule out any visa considerations (unless you need a workers visa to work as a consultant?).

• Issuing multiple requests using HTTP/1.1 Pipelining

  - by Robert S. Barnes

  When using HTTP/1.1 Pipelining what does the standard say about issuing multiple requests without waiting for each request to complete? What do servers do in practice? I ask because I once tried writing a client which would issue a batch of GET requests for multiple files and remember getting errors. I wasn't sure if it was due to me incorrectly issuing the GET's or needing to wait for each individual request to finish before issuing the next GET.

• Extend Javascript Date Object

  - by jAndy

  Hi Folks, I'm curious what would be the best practice to extend the Date constructor. The problem I'm facing is, that the Internet Explorer (< 7+8) can't parse a date like new Date('2010-05-11'); I have to admit that this is not a standard method to parse, anyways FireFox and Chrome perform well on that kind of date string. Now I'm wondering, should I just split/parse/rebuild the string before calling new Date() or is there a more elegant solution ?

• Is it possible to make an alarm using NSTimer and UIDatepicker?

  - by user557425

  I have an app which plays some ambient noises. I have fitted it with a sleep timer and a local notifier which work fine, but the notifier will only fire when the app is in the background. I would like to be able to fit a standard alarm clock that the user can set using the date picker, ie, the user picks 07:15 am on the date picker and this triggers a sound being played at this time. Can this be done?

• Cannot get Request.Form by name in ASP.NET

  - by Nissan Fan

  I have an ASP.NET page which utilizes jQuery for an autocomplete-type scenario. The jQuery tucks the actual selected values into a hidden field it creates on the fly, but for some reason I cannot get the value of that standard HTML field on postback by calling Request.Form["HiddenFieldName"]. I can see it by ordinal in the Request.Form object, but if I add/remove controls it will break. Any suggestions?

• .NET - alpha-numeric representation of numbers

  - by mack369

  I'm implementing serial key functionality in my application. User needs to enter at least 64bit number in order to register the application. Because typing number like 9,223,372,036,854,775,807 will take a while I want to compress it a bit. The first guess was to code this number hexadecimally but it still is quite long (0x7FFF FFFF FFFF FFFF). Is there any standard method in .NET to code this number alphanumerically using for example: digits, upper-case and lower-case characters?
