  • Trap error or 'Resume Next'

    - by Craig Johnston
    I realise this is an older programming environment, but I have to clean up some VB6 code and I am finding that most of it uses: Resume Next What is the general consensus about the use of Resume Next? Surely, if there is an error, you would want the app to stop what it was doing, rollback any data changes, and inform the user of the error, rather than just resuming. When is it good idea to use Resume?

  • CFBundleDocumentTypes & UIFileSharingEnabled issues

    - by carloe
    Has anyone gotten UIFileSharingEnabled or CFBundleDocumentTypes to work? I added UIFileSharingEnabled as true to my plist and used Apple's example from the link below for CFBundleDocumentTypes, but can't seem to get it to work. I don't see my app under file sharing in iTunes, and I do not get the option to open documents I registered in my app when I click on them in the mail.app http://developer.apple.com/iphone/library/documentation/General/Conceptual/iPadProgrammingGuide/CoreApplication/CoreApplication.html

  • Exporting Stata results

    - by Max M.
    I'm sure this is an issue anyone who uses Stata for publications or reports has run into: how do you conveniently export your output to something that can be parsed by a scripting language or Excel? There are a few ADO files that to this for specific commands (try findit tabout or findit outreg2). But what about exporting the output of the table command? Or the results of an anova? I'd love to hear about how Stata users address this problem for either specific commands or in general.

  • Simple question about MKMapView and the iPhone

    - by gravityone
    Basically I want to show the users location plus a list of selected location on a map. It can even have the standard iphone annotations. But, I have no idea of the general steps I would take to achieve this. Would I use MKMapView, or Core Location, or both? Could someone give me a simple outline of steps to take, or a link to a good tutorial or sample code. Thanks

  • Finding patterns in source code

    - by trex279
    If I wanted to learn about pattern recognition in general what would be a good place to start (recommend a book)? Also, does anybody have any experience/knowledge on how to go about applying these algorithms to find abstraction patterns in programs? (repeated code, chunks of code that do the same thing, but in slightly different ways, etc.) Thanks Edit: I don't mind mathematically intensive books. In fact, that would be a good thing.

  • Mathematica equivalent of Ruby's inject

    - by Ben Alpert
    Is there a Mathematica function like inject in Ruby? For example, if I want the product of the elements in a list, in Ruby I can write: list.inject(1) { |prod,el| prod * el } I found I can just use Product in Mathematica: Apply[Product, list] However, this isn't general enough for me (like, if I don't just want the product or sum of the numbers). What's the closest equivalent to inject?

  • New to asp.net. Need help debugging this email form.

    - by Roeland
    Hey guys, First of all, I am a php developer and most of .net is alien to me which is why I am posting here! I just migrated over a site from one set of webhosting to another. The whole site is written in .net. None of the site is database driven so most of it works, except for the contact form. The output on the site simple states there was an error with "There has been an error - please try to submit the contact form again, if you continue to experience problems, please notify our webmaster." This is just a simple message it pops out of it gets to the "catch" part of the email function. I went into web.config and changed the parameters: <emailaddresses> <add name="System" value="[email protected]"/> <add name="Contact" value="[email protected]"/> <add name="Info" value="[email protected]"/> </emailaddresses> <general> <add name="WebSiteDomain" value="hoyespharmacy.com"/> </general> Then the .cs file for contact contains the mail function EmailFormData(): private void EmailFormData() { try { StringBuilder body = new StringBuilder(); body.Append("Name" + ": " + txtName.Text + "\n\r"); body.Append("Phone" + ": " + txtPhone.Text + "\n\r"); body.Append("Email" + ": " + txtEmail.Text + "\n\r"); body.Append("Fax" + ": " + txtEmail.Text + "\n\r"); body.Append("Subject" + ": " + ddlSubject.SelectedValue + "\n\r"); body.Append("Message" + ": " + txtMessage.Text); MailMessage mail = new MailMessage(); mail.IsBodyHtml = false; mail.To.Add(new MailAddress(Settings.GetEmailAddress("System"))); mail.Subject = "Contact Us Form Submission"; mail.From = new MailAddress(Settings.GetEmailAddress("System"), Settings.WebSiteDomain); mail.Body = body.ToString(); SmtpClient smtpcl = new SmtpClient(); smtpcl.Send(mail); } catch { Utilities.RedirectPermanently(Request.Url.AbsolutePath + "?messageSent=false"); } } How do I see what the actual error is. I figure I can do something with the "catch" part of the function.. Any pointers? Thanks!

  • Error while attempting to output data onto console in xcode

    - by Michael Amici
    I am trying to output general data (source code) from a website, but it just sits there. Can't figure out if its the interface or the code. Would someone double-check for me? #import "Lockerz_RedemptionViewController.h" @implementation Lockerz_RedemptionViewController -(IBAction)start: (id) sender { while (1) { NSMutableData *mydata = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:@"http://ptzplace.lockerz.com/"]]; NSString *output = [[NSString alloc] initWithData:mydata encoding:NSASCIIStringEncoding]; NSLog(output); } }

  • How to safely use VSS when using a working directory on a thumb drive?

    - by MatthewMartin
    I know putting code into VSS in general is as safe as putting money into a mutual fund run by Bernard Madoff, but I don't have the luxury of ditching it for subversion. That said, I need to be able to write code on two machines, I'm considering checking out code to a flash thumb drive. Anyone know in advance what I should/shouldn't do to avoid loss of work? Do I need to ensure the drive letter stays the same?

  • Which languages are dynamically typed and compiled (and which are statically typed and interpreted)?

    - by Skilldrick
    In my reading on dynamic and static typing, I keep coming up against the assumption that statically typed languages are compiled, while dynamically typed languages are interpreted. I know that in general this is true, but I'm interested in the exceptions. I'd really like someone to not only give some examples of these exceptions, but try to explain why it was decided that these languages should work in this way.

  • How do I move from being a software developer to being a software architect?

    - by Nestor
    I mean... Should I start programming less and designing more? Should I stop reading programming books, and start reading more books about pattern designs, etc? Should I stop focusing primarily on Microsoft technologies and open up my horizons with other technologies (in order to get a broader perspective)? How should I change my mind set in general (perhaps less detail oriented) ? etc I'm looking for concrete advice, especially from your own experience!

  • packaging and distributing Python code as executables

    - by user248237
    How can I compile my python module into an executable, and distribute it in a way that doesn't require the user to download all the external Python packages that the module I wrote uses? Aside from that, is there a general guy on packaging and distributing python code? i.e. going from a script/module to someone that's user-friendly and can be run, ideally cross-platform (at least between unix and mac). thanks.
