  • django + xmppy: send a message to two recipients

    - by Agrajag
    I'm trying to use xmpppy for sending jabber-messages from a django-website. This works entirely fine. However, the message only gets sent to the -first- of the recipients in the list. This happens when I run the following function from django, and also if I run it from an interactive python-shell. The weird part though, is that if I extract the -body- of the function and run that interactively, then all the recipients (there's just 2 at the moment) get the message. Also, I do know that the inner for-loop gets run the correct count times (2), because the print-statement does run twice, and return two different message-ids. The function looks like this: def hello_jabber(request, text): jid=xmpp.protocol.JID(settings.JABBER_ID) cl=xmpp.Client(jid.getDomain(),debug=[]) con=cl.connect() auth=cl.auth(jid.getNode(),settings.JABBER_PW,resource=jid.getResource()) for friend in settings.JABBER_FRIENDS: id=cl.send(xmpp.protocol.Message(friend,friend + ' is awesome:' + text)) print 'sent message with id ' + str(id) cl.disconnect() return render_to_response('jabber/sent.htm', locals())

  • Problem with averaging corrupted images to eliminate the noise in MATLAB

    - by Mertie Pertie
    I want to average some .jpg images which are corrupted by zero-mean Gaussian additive noise. After searching around, I figured out to add the image matrices and divide the sum by the number of matrices. However, the resultant image is totally black. Normally when the number of image increases then the resultant image gets better. But when I use more images it gets darker. I am using 800x600 black and white .jpg images. Here is the script I used: image1 = imread ('PIC1.jpg'); image2 = imread ('PIC2.jpg'); image3 = imread ('PIC3.jpg'); image4 = imread ('PIC4.jpg'); sum = image1 + image2 + image3 + image4; av = sum / 4; imshow(av);

  • How do I stop server control attributes being HTML encoded?

    - by Billious
    I'm trying to alter the onmouseover attribute of a HyperLink server control, but when I do so the JavaScript call I'm entering gets HTML encoded. For example: linkBooks.Attributes("onmouseover") = "changeImages(""books"", ""/images/common/books-dark.png""); return true;" Gets converted to: onmouseover="changeImages(&quot;books&quot;, &quot;/images/common/books-dark.png&quot;); return true;" How do I prevent this? The same code worked fine under VS2005 and .NET 2.0, I'm currently using VS2010RC and .NET 4.0.

  • MasterPage Page_Load hits before Grid_ItemCommand

    - by Raheel Khan
    I am using the session object to store success/error messages based on user actions. On each postback, the message is set on ItemCommend and retrieved on the Page_Load of the master page. Once retrieved, the message is deleted from the session. The problem is that the master page's Page_Load gets called before the ItemCommand gets called so the message does not show up until the next refresh or postback. How is this situation normally handled? Is there some other event we can code against?

  • How to observe NSScroller changes?

    - by Paperflyer
    I have an NSScrollView subclass and I would like to update another NSView based on the current scroll position. I tried KVC-observing the value of [self horizontalScroller] but that never gets called. // In awakeFromNib [[self horizontalScroller] addObserver:self forKeyPath:@"value" options:NSKeyValueObservingOptionNew context:NULL]; // Later in the file - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { if (object == [self horizontalScroller] && [keyPath isEqualToString:@"value"]) { // This never gets called } } Do you see an error in my reasoning or know a better method of how to observe the scrolling of an NSScrollview?

  • one primary key column foreign key to 2 other table columns.How to resolve data entry issue.

    - by Rohit
    I have a requirement according to which I have to create a central Login system.We have 2 things Corporate and Brand each represented by tables "Corporate" and "Brand". When a corporate gets registered,corporateID is given,When a user under that corporate gets registered there is a table corporateuser in which corporateID is a foreign key and CorporateUserID is a primary key.Similarly in the case of a brand. So we have CorporateUserId and BrandUserID. Now i have a table called RegisteredUsers in which i want to have corporate as well as brand users.UserID is a primary key in this table which is a foreign key to both corporateuser as well as Branduser. now when i enter a corporateuser,I do an entry to corporateuser as well as RegisteredUsers.When i enter CorporateUserID in userID for RegisteredUsers.It gives foreign key violation error. I fully understand this error.How can i achieve this.This requirement is very rigid.Please tell a workaround

  • Html dynamically repeated border-image

    - by Clox
    I have a table which border I want to have a sort of zig-zag shape. I want the table to have an automatic size; resizing depending on how big the browser is. But rrathe than just having an image that gets stretched I want a seamless image that gets repeat instead. I found out this can be done with CSS3's Border-image but by looking and Browser Statistics I can see than only about half of all the viewers will be able to see it since no version of IE does yet support it. So I'm looking for an alternate method. What would be the best way of doing it? Thanks in advance!

  • R: simple and short if clauses for combind statements

    - by jorgusch
    Hello, TRUE/FALSE if clauses are easily and quickly done in R. However, if the argument gets more complex, it also gets ugly very soon. For instance: I might want to execute different operations for a row(foo) dependent on the value in one cell (foo[1]). Let the intervals be 0:39 and 40:59 and 60:100 Something like does not exit: (if foo[1] "in" 40:60){... In fact, I only see ways of at least two if clauses and two else statements and the action for the first interval somewhere at the bottom of the code. With more intervals(or any other condition) it is getting more complex. Is there a best practice (for this purpose or others) with a simple construction and nice design to read? Thanks a lot!

  • Java Archtecture Decision !!

    - by santiagobasulto
    Hi everybody! I'm developing a medium Java app, and i'm facing a small problem due to my lack of expirience. I've a custom DAO, which gets "Article" objects from the DataBase. I've the Article class, and the DAO has a method called getArticle(int id), this method returns an Article. The Article has a Category object, and i'm using lazy loading. So, when i request for an Article Category (Article a = new Article(); a.getCategory();) the Article class gets the Category from the DAO and then returns it. I'm now thinking to cache it, so when i request multiple times to an Article's category, the database is only queried one time. My question is: where should i put that cache? I can put it on the Article class (in the DTO), or i can put it on the DAO class. What do you say? Thanks!

  • mocking command object in grails controller results in hasErrors() return false no matter what! Plea

    - by egervari
    I have a controller that uses a command object in a controller action. When mocking this command object in a grails' controller unit test, the hasErrors() method always returns false, even when I am purposefully violating its constraints. def save = { RegistrationForm form -> if(form.hasErrors()) { // code block never gets executed } else { // code block always gets executed } } In the test itself, I do this: mockCommandObject(RegistrationForm) def form = new RegistrationForm(emailAddress: "ken.bad@gmail", password: "secret", confirmPassword: "wrong") controller.save(form) I am purposefully giving it a bad email address, and I am making sure the password and the confirmPassword properties are different. In this case, hasErrors() should return true... but it doesn't. I don't know how my testing can be any where reliable if such a basic thing does not work :/ Here is the RegistrationForm class, so you can see the constraints I am using: class RegistrationForm { def springSecurityService String emailAddress String password String confirmPassword String getEncryptedPassword() { springSecurityService.encodePassword(password) } static constraints = { emailAddress(blank: false, email: true) password(blank: false, minSize:4, maxSize: 10) confirmPassword(blank: false, validator: { confirmPassword, form -> confirmPassword == form.password }) } }

  • Wizard based feature install in sharepoint 2007?

    - by JL
    I have a feature that gets installed using a WSP package, when the feature is activated, I would like the following to happen: The feature will contain a list definition. When the feature gets activated by an end user (the user physically clicks the feature activation button in site features admin) - I would like a modal dialog to appear then ask the user to provide some additional details. 3.1 The additional details will be supplying a certain number of names. For example Mary, John, Peter. Form logistics I can handle. Once the form is complete that information needs to somehow get back to the feature reciever, so that I can then take the base list definition, and use it as a template to create list instances for all the names supplied - so if user had supplied Mary and Peter, then 2 list instances will be created when this feature is activated. Is any of this possible with MOSS 2007? Thank you

  • Internet Explorer 8 EmulateIE7 Mode not working

    - by Ryu
    I've set up IIS6 to send the following headers Custom Header Name: X-UA-Compatible Custom Header Value: IE=EmulateIE7 that supposed to force IE 8 into IE 7 Compatibility mode. You can read more about it on MSDN . I have noticed by looking in the Developer toolbar that if I have a DTD defined the document mode correctly gets set to IE 7, but the browser mode is IE 8. If the page doesn't have a DTD the document mode gets set to Quirks and Browser Mode once again IE 8. Am I doing something wrong. How do I force IE 8 to set IE 7 Browser mode. Thanks

  • Visual C++ 2008 doesn't recognize Windows declared types

    - by David Thornley
    I have a program that doesn't seem to recognize declared types in the latest U3D software. There's a line typedef BOOL (WINAPI* GMI)(HMON, LPMONITORINFOEX); which gets the error: Error 1 error C2061: syntax error : identifier 'LPMONITORINFOEX' c:\Projects\U3D\Source\RTL\Platform\Common\Win32\IFXOSRender.cpp 28 and a line MONITORINFOEX miMon; which gets Error 5 error C2065: 'miMon' : undeclared identifier c:\Projects\U3D\Source\RTL\Platform\Common\Win32\IFXOSRender.cpp 49 Error 3 error C2065: 'MONITORINFOEX' : undeclared identifier c:\Projects\U3D\Source\RTL\Platform\Common\Win32\IFXOSRender.cpp 49 The program's first non-comment statement is #include <windows.h>, which includes winuser.h, which defines these identifiers. In Visual Studio, I can right-click on them and go to the definition (a typedef) and from the typedef to the struct. WINAPI is defined in WinDef.h, so that seems to be working. There are no redefinitions of LPMONITORINFOEX or MONITORINFOEX in any other file. So, how can this be happening, and what can I do about it?

  • convert from physical path to virtual path

    - by user710502
    I have this function that gets the fileData as a byte array and a file path. The error I am getting is when it tries to set the fileInfo in the code bewlo. It says 'Physical Path given, Virtual Path expected' public override void WriteBinaryStorage(byte[] fileData, string filePath) { try { // Create directory if not exists. System.IO.FileInfo fileInfo = new System.IO.FileInfo(System.Web.HttpContext.Current.Server.MapPath(filePath)); //when it gets to this line the error is caught if (!fileInfo.Directory.Exists) { fileInfo.Directory.Create(); } // Write the binary content. System.IO.File.WriteAllBytes(System.Web.HttpContext.Current.Server.MapPath(filePath), fileData); } catch (Exception) { throw; } } When debugging it, is providing the filePath as "E:\\WEBS\\webapp\\default\\images\\mains\\myimage.jpg" . And the error message is 'E:/WEBS/webapp/default/images/mains/myimage.jpg' is a physical path, but a virtual path was expected. Also, what it is triggering this to happen is the following call properties.ResizeImage(imageName, Configurations.ConfigSettings.MaxImageSize, Server.MapPath(Configurations.EnvironmentConfig.LargeImagePath));

  • reloadData not working - suspect cell's reuseIdentifier

    - by retailevolved
    I have a view controller that gets presented modally and changes some data that effects the data in a uitableview in the modal's parent view controller (a table view). I call the tableview's reloadData method when the parent view reappears. I have confirmed that this code gets hit with a break point. My trouble is, reloadData isn't working. Here's the kicker - if I don't use reuseIdentifiers in the - (UITableViewCell *)cellForRowAtIndexPath:(NSIndexPath *)indexPath method, the data reloads correctly. It looks like the reuseIdentifier is to blame. I really want to continue to use the reuseIdentifier for my cells - how do I make this work?

  • Frame skipping with OpenGL and WinAPI?

    - by user146780
    Here is my situation. I'm creating a drawing application using OpenGL and WinAPI. My OpenGL frame has scrollbars which renders the screen and modifies GlTranslatef when it gets a scroll message. The problem is wen I get too many shapes the scrollbar is less responsive since it cannot rerender it each and every time it gets a scroll message. How could I make it so the scrollbar has priority. I want it to skip drawing if it would compromise the smoothness of the scrolling. I thought of doing rendering on a separate thread but I was told all UI things should stay on the same thread. Thanks

  • Postgresql sequences

    - by Dylan
    When I delete all records from a Postgresql table and then try to reset the sequence to start a new record with number 1 when it is inserted, i get different results : SELECT setval('tblname_id_seq', (SELECT COALESCE(MAX(id),1) FROM tblname)); This sets the current value of the sequence to 1, but the NEXT record (actually the first because there are no records yet) gets number 2! And I can't set it to 0, because the minimum value in the sequence is 1! When I use : ALTER SEQUENCE tblname_id_seq RESTART WITH 1; the first record that is inserted actually gets number 1 ! But the above code doesn't accept a SELECT as a value instead of 1. I wish to reset the sequence to number 1 when there are no records, and the first record then should start with 1. But when there ARE already records in the table, I want to reset the sequence so that the next record that is inserted will get {highest}+1 Does anyone have a clear solution for this?

  • boolean type for while loop in bash?

    - by user151841
    I have a cron script on a shared web host that occasionally gets killed. I'd like to make a loop in bash that tries again if it gets killed, because most of the time it will make it. I'm having trouble with the syntax for storing a boolean value :P #!/bin/bash VAR=0; while [ $VAR ]; do if nice -19 mysqldump -uuser -ppassword -h database.hostname.com --skip-opt --all --complete-insert --add-drop-table database_name > ~/file/system/path/filename.sql; then VAR=1; fi done So the script recovers from a killed process okay, but once it's run properly, the new VAR value doesn't kill the while loop. What am I doing wrong?

  • Averaging corrupted images to eliminate the noise

    - by Mertie Pertie
    Hi all As you can get it from the title, I want to average some .jpg images which are corrupted by zero-mean Gaussian additive. After searching over internet, I figured out to add image matrices and divide the sum by the # of matrices. However the resultant image is totally black. Normally when the number of image increases then the resultant image gets better. But When I use more images it gets darker. I am using 800x600 black and white images with .jpg ext Here is the script I used; image1 = imread ('PIC1.jpg'); image2 = imread ('PIC2.jpg'); image3 = imread ('PIC3.jpg'); image4 = imread ('PIC4.jpg'); sum = image1 + image2 + image3 + image4; av = sum / 4; imshow(av); Thanks in advance
