Determine the path of the executing BASH script

- by Atif Aziz

In a Windows command script, one can determine the directory path of the currently executing script using %~dp0. For example: @echo Running from %~dp0 What would be the equivalent in a BASH script?

OK..So John Papa, Nasir Aziz and myself are trying to help Victor Gaudioso figure out why he can’t see the ADO.NET Entity Data Model template in Visual Studio 2010. At first I thought maybe he was using the Pro version and this was one of those oddities. (After all I’m using the Ultimate version and I also see this template in the Express version.) Nope..Vic was also using VS2010 Ultimate. Believe me Vic is a Silverlight and WPF genius and knows his way around in VS. He was working with the latest...(read more)

I have an Excel spreadsheet containing a list of strings. Each string is made up of several words, but the number of words in each string is different.

How do I combine MVCContrib's "Rescue" with Elmah?

- by Chris

I got the Rescue attribute working. It properly serves up the DefaultError view when there is an unhandled exception. However, these exceptions will not get logged or emailed. This SO question is answered by Atif Aziz and it looks pretty solid, but it applies to the built-in HandleErrorAttribute, which Rescue replaces, right? How do I get that to work with Rescue? I want to make sure that if an unhandled exception arises, that the user gets served up the view specified with the Rescue attribute, but the exception is still properly logged, and viewable with elmah.axd.

How can I make Mac OS X Address Book display a person’s home address from an LDAP server?

- by Arcturus

Hi, (I've posted this question on Stack Overflow first, but someone told me it belonged here.) I have a custom LDAP server, which I can customize to generate whichever object class and attributes I need. I'm trying to display people from that server in the Mac OS X address book. Names and organizations display correctly, as well as work-related phone and address. However, I've never been able to have a home address displayed in the address book. This is an example of output from running a ldapsearch: # extended LDIF # # LDAPv3 # base <dc=example,dc=com> with scope subtree # filter: (givenName=Joh*) # requesting: ALL # # 10041, example.com dn: uid=10041,dc=example,dc=com objectclass: top objectclass: person objectclass: organizationalPerson objectclass: inetOrgPerson objectclass: mozillaOrgPerson uid: 10041 cn: John Doe givenName: John sn: Doe o: Acme telephoneNumber: 500 00 00 mobile: 500 00 00 mail: [email protected] street: Baker St postalCode: 10098 l: New York c: US homePostalAddress: White St mozillaHomePostalCode: 10098 mozillaHomeLocalityName: New York mozillaHomeCountryName: US # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 Every piece of information shows up in the address book up to here: homePostalAddress: White St mozillaHomePostalCode: 10098 mozillaHomeLocalityName: New York mozillaHomeCountryName: US Which object class or attribute name should I use to have the home address show up in the Mac OS X address book?

ASP.NET MVC HandleError Attribute

- by Ben Griswold

Last Wednesday, I took a whopping 15 minutes out of my day and added ELMAH (Error Logging Modules and Handlers) to my ASP.NET MVC application. If you haven’t heard the news (I hadn’t until recently), ELMAH does a killer job of logging and reporting nearly all unhandled exceptions. As for handled exceptions, I’ve been using NLog but since I was already playing with the ELMAH bits I thought I’d see if I couldn’t replace it. Atif Aziz provided a quick solution in his answer to a Stack Overflow question. I’ll let you consult his answer to see how one can subclass the HandleErrorAttribute and override the OnException method in order to get the bits working. I pretty much took rolled the recommended logic into my application and it worked like a charm. Along the way, I did uncover a few HandleError fact to which I wasn’t already privy. Most of my learning came from Steven Sanderson’s book, Pro ASP.NET MVC Framework. I’ve flipped through a bunch of the book and spent time on specific sections. It’s a really good read if you’re looking to pick up an ASP.NET MVC reference. Anyway, my notes are found a comments in the following code snippet. I hope my notes clarify a few things for you too. public class LogAndHandleErrorAttribute : HandleErrorAttribute { public override void OnException(ExceptionContext context) { // A word from our sponsors: // http://stackoverflow.com/questions/766610/how-to-get-elmah-to-work-with-asp-net-mvc-handleerror-attribute // and Pro ASP.NET MVC Framework by Steven Sanderson // // Invoke the base implementation first. This should mark context.ExceptionHandled = true // which stops ASP.NET from producing a "yellow screen of death." This also sets the // Http StatusCode to 500 (internal server error.) // // Assuming Custom Errors aren't off, the base implementation will trigger the application // to ultimately render the "Error" view from one of the following locations: // // 1. ~/Views/Controller/Error.aspx // 2. ~/Views/Controller/Error.ascx // 3. ~/Views/Shared/Error.aspx // 4. ~/Views/Shared/Error.ascx // // "Error" is the default view, however, a specific view may be provided as an Attribute property. // A notable point is the Custom Errors defaultRedirect is not considered in the redirection plan. base.OnException(context); var e = context.Exception; // If the exception is unhandled, simply return and let Elmah handle the unhandled exception. // Otherwise, try to use error signaling which involves the fully configured pipeline like logging, // mailing, filtering and what have you). Failing that, see if the error should be filtered. // If not, the error simply logged the exception. if (!context.ExceptionHandled || RaiseErrorSignal(e) || IsFiltered(context)) return; LogException(e); // FYI. Simple Elmah logging doesn't handle mail notifications. }
