  • Setting up App Engine to receive email addresses with ids in the address

    - by Mark M
    I am writing an App Engine app that is supposed to receive emails in this form: [email protected] (someID is an alphanumeric ID that I generate). I have this in my web.xml thinking it would catch emails that start with 'addcontact.': <servlet> <servlet-name>addNewContactServlet</servlet-name> <servlet-class>com.mycompany.server.AddNewContactServlet</servlet- class> </servlet> <servlet-mapping> <servlet-name>addNewContactServlet</servlet-name> <url-pattern>/_ah/mail/addcontact.*</url-pattern> </servlet-mapping> However, both on my dev machine and on google's servers email is not received. On the dev machine I get this message (I get a similar error in the deployed log) Message send failure HTTP ERROR 404 Problem accessing /_ah/mail/ [email protected]. Reason: NOT_FOUND I can receive email at fully specified addresses or when I use /_ah/mail/* The google documentation made me believe it was possible to include partial email addresses in web.xml. Am I not using the wildcard correctly? Does the period have something to do with it? Can this be done somehow?

  • Storing information for drop-down menus

    - by Mark
    Suppose you're building an HTML form and you want to have 2 or more drop-down menus, where after picking an option from the first, the 2nd menu is populated, and so forth. For example, choosing a country would bring up a list of provinces for that country, which would in turn list the cities. How would you store that sort of information in a database? Would you have a table Countries(id, name), Provinces(id, country_id, name), Cities(id, province_id, name) or would you have just one big denormalized table Entries(country, province, city)? (Why?)

  • How can I initialize a 2d array in Perl?

    - by Mark
    How do I initialize a 2d array in perl? I am trying the following code: 0 use strict; 10 my @frame_events = (((1) x 10), ((1) x 10)); 20 print "$frame_events[1][1]\n"; but it gives the following error: Can't use string ("1") as an ARRAY ref while "strict refs" in use at ./dyn_pf.pl line 20. This syntax only seems to initialize a 1d array as print "$frame_events[1]\n" works. Though perl doesn't give any error during the assignment.

  • std::make_shared as a default argument does not compile

    - by Mark Bryant
    In Visual C++ (2008 and 2010), the following code does not compile with the following error: #include <memory> void Foo( std::shared_ptr< int > test = ::std::make_shared< int >( 5 ) ) { } class P { void Foo( std::shared_ptr< int > test = ::std::make_shared< int >( 5 ) ) { } }; error C2039: 'make_shared' : is not a member of '`global namespace'' error C3861: 'make_shared': identifier not found It is complaining about the definition of P::Foo() not ::Foo(). Does anybody know why it is valid for Foo() to have a default argument with std::make_shared but not P::Foo()?

  • Moving UITableView cells and maintaining consistent data

    - by Mark F
    I've enabled editing mode and moving cells around to allow users to position table view content in the order they please. I'm using Core Data as the data source, which sorts the content by the attribute "userOrder". When content is first inserted, userOrder is set to a random value. The idea is that when the user moves a cell around, the userOrder of that cell changes to accomodate its new position. The following are problems I am running into while trying to accomplish this: Successfully saving the the new location of the cell and adjusting all changed locations of influenced cells. Getting the data to be consistent. For example, the TableView handles the movement fine, but when i click on the new location of the cell, it displays data for the old cell that used to be that location. Data of all influenced cells gets messed up as well. I know I have to implement this in: - (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath {} I just don't know how. The apple docs are not particularly helpful if you are using Core Data, as in my situation. Any guidance greatly appreciated!

  • Book recommendation for project architecture?

    - by Mark
    I already have a solid knowledge of Object-oriented PHP as well as HTML/Javascript/MySQL plus a basis in Java. Now I would like to implement my projects in an efficient way, whether it is a web project in PHP or an Android application. My problem is once my code gets bigger I start messing error handling, with form validation etc, and I guess its because of my poor basis in software architecture. Thanks.

  • Viewing directory containing MIME encoded email messages

    - by Mark
    I have an application which generates and sends MIME encoded messages (javax.mail.internet.MimeMessage) through an SMTP server. As part of the development process only, I'd like to be able to view these messages rather than send them (I know the sending works just fine, but there are restrictions on the domains within the dev environment which makes it a little difficult) I thought the easiest way would be to save the text for each message to a directory, then point "an app" at the directory and check them over. So the question is, what would be a good app to use? Is it as simple as configuring Outlook or another email client to do it? Thanks

  • How to set ItemsSource?

    - by Mark
    This dialog makes no sense to me And I'm having trouble finding good tutorials on it. Most of the examples aren't detailed enough, or do stuff via code, but I'd like to take advantage of the IDE as much as possible. Whats the difference between ItemsSource and DataContext? I'd like to bind it to just a List for starters. I don't need SQL or databases or anything fancy. Where would I declare my list? In MainWindow.xaml.cs? How do I get it to appear in that dialog?

  • Excel I have a .Net object compiled as a tlb but cant not access any methods apart from Dispose.

    - by Mark O'Grady
    Hi This is ongoing issue to something I posted yesterday. I have a .net object that I want to use in Excel. I have an existing VBA script that i need to alter to call this the object from. I have then converted the object to a TLB. I've not really touched on this area before so any help will be appreciated. I have created an interface [Guid("0F700B48-E0CA-446b-B87E-555BCC317D74"),InterfaceType(ComInterfaceType.InterfaceIsDual)] [ComVisible(true)] public interface IOfficeCOMInterface { [DispId(1)] void ResetOrder(); [DispId(2)] void SetDeliveryAddress(string PostalName, string AddressLine1, string AddressLine2, string AddressLine3, string AddressLine4, string PostCode, string CountryCode, string TelephoneNo, string FaxNo, string EmailAddress); } I have also created an class that inherits that object. [ClassInterface(ClassInterfaceType.None), ProgId("NAMESPACE.OfficeCOMInterface"), Guid("9D9723F9-8CF1-4834-BE69-C3FEAAAAB530"), ComVisible(true)] public class OfficeCOMInterface : IOfficeCOMInterface, IDisposable { public void ResetSOPOrder() { } public void SetDeliveryAddress(string PostalName, string AddressLine1, string AddressLine2, string AddressLine3, string AddressLine4, string PostCode, string CountryCode, string TelephoneNo, string FaxNo, string EmailAddress) { try { SalesOrder.AmendDeliveryAddress(PostalName, AddressLine1, AddressLine2, AddressLine3, AddressLine4, PostCode); MessageBox.Show("Delivery address set"); } catch (Exception ex) { throw ex; } } } I can't access the object methods apart from dispose, I guess IDisposable is working fine. Is there anything I need to my Interface?

  • Oracle: what information can I derive from the SCN?

    - by Mark Harrison
    Given an SCN (system change number), and assuming an SCN for which the data is still in the undo logs, what information about the SCN can I derive? of course, SCN_TO_TIMESTAMP() gives an approximate time the data was committed. Is there any other information I can derive? What transaction, what tables, what data were affected? etc?

  • When is `x IS NOT NULL` not the same as `NOT(x IS NULL)`

    - by Mark Hurd
    For what x is The expression x IS NOT NULL is not equal to NOT(x IS NULL), as is the case in 2VL (quote from this answer, which is quoting Fabian Pascal Practical Issues in Database Management - A Reference for the Thinking Practitioner -- near the end of that answer) My guess is when x IS NULL is NULL, but I cannot guess when that would be (i.e. I haven't checked the SQL standard).

  • Customizing Django Form: Required and InputId?

    - by Mark
    I'm trying to customize how my form is displayed by using a form_snippet as suggested in the docs. Here's what I've come up with so far: {% for field in form %} <tr> <th><label for="{{ field.html_name }}">{{ field.label }}:</label></th> <td> {{ field }} {% if field.help_text %}<br/><small class="help_text">{{ field.help_text }}</small>{% endif %} {{ field.errors }} </td> </tr> {% endfor %} Of course, field.html_name is not what I'm looking for. I need the id of the input field. How can I get that? Also, is there a way I can determine if the field is required, so that I can display an asterisk beside the label?

  • How do I write a regex that ignores strings starting with a particular prefix, and captures everythi

    - by Mark Rogers
    Background: I'm trying to come up with a regex for a rewrite rule that will take anything that does not start with a particular prefix, and add that prefix to it. But urls that already have the prefix should be rejected by the regular expression (because they already have the url). Example: If the prefix is s1 a string like home will capture the home part. But a string like s1/home, will not capture anything. This way I can add the capture group onto the prefix, so that 'home' will become 's1/home'. I've tried (^s1/), but I'm missing something here, because that rejected 'home' for some reason.

  • SFTP in Python? (platform independent)

    - by Mark Wilbur
    I'm working on a simple tool that transfers files to a hard-coded location with the password also hard-coded. I'm a python novice, but thanks to ftplib, it was easy: import ftplib info= ('someuser', 'password') #hard-coded def putfile(file, site, dir, user=(), verbose=True): """ upload a file by ftp to a site/directory login hard-coded, binary transfer """ if verbose: print 'Uploading', file local = open(file, 'rb') remote = ftplib.FTP(site) remote.login(*user) remote.cwd(dir) remote.storbinary('STOR ' + file, local, 1024) remote.quit() local.close() if verbose: print 'Upload done.' if __name__ == '__main__': site = 'somewhere.com' #hard-coded dir = './uploads/' #hard-coded import sys, getpass putfile(sys.argv[1], site, dir, user=info) The problem is that I can't find any library that supports sFTP. What's the normal way to do something like this securely? Edit: Thanks to the answers here, I've gotten it working with Paramiko and this was the syntax. import paramiko host = "THEHOST.com" #hard-coded port = 22 transport = paramiko.Transport((host, port)) password = "THEPASSWORD" #hard-coded username = "THEUSERNAME" #hard-coded transport.connect(username = username, password = password) sftp = paramiko.SFTPClient.from_transport(transport) import sys path = './THETARGETDIRECTORY/' + sys.argv[1] #hard-coded localpath = sys.argv[1] sftp.put(localpath, path) sftp.close() transport.close() print 'Upload done.' Thanks again!

  • HTML5: Rendering absolute images using canvas

    - by Mark
    I am experimenting with canvas as part of my HTML5 introduction. This constitutes as assignment work, but I am not asking for any help on the actual coursework at all. I am trying to write a rendering engine, but having no luck because once the image is drawn on canvas it looks very distorted, and not at the right dimensions of the image itself. I have made a animation engine that loads images into an array, and then iterates through them at a certain speed. This is not the problem, and I assume is not causing the issue as this was happening when I drawn an image to the canvas. I think this is natural behaviour for images to be scaled/skewed when the window is resized, so I conquered that by simply redrawing the whole thing once the window is resized. The images I am using are isometric, and drawn at a pixel level. Would this cause the distortion? It seems setting the dimensions on the drawImage() function are not working are all. I am using JavaScript for the manipulation and rendering of the canvas. I would normally try and work it out myself, but I do not have any time to ponder why because I have no idea why it is even scaling/skewing the image once it is drawn on the canvas. I cannot share the code for obvious reasons. I should also mention, the canvas's dimension is the total width of the viewport, as I am developing a game. My question is: Has anyone encountered this and how would I correct it? Thanks for your help.

  • MediaWiki: workaround for watchlist restricted to 7 days?

    - by Mark Robinson
    I'm running MediaWiki 1.13.2. When I go to my watchlist, I'm limited to only viewing the last 7 days (though MediaWiki should permit me to view the last 30 days). I've tried: Clicking the all button Changing the URL Changing the settings under MY PREFERENCES-WATCHLIST. When I save (e.g. 30 days) it resets back to 7 days! Googling for an answer... Anyone heard of this bug before? Is there a workaround? I can't see a setting anywhere for this to be a maximum.
