• plotting results of hierarchical clustering ontop of a matrix of data in python

  - by user248237

  How can I plot a dendrogram right on top of a matrix of values, reordered appropriately to reflect the clustering, in Python? An example is in the bottom of the following figure: http://www.coriell.org/images/microarray.gif I use scipy.cluster.dendrogram to make my dendrogram and perform hierarchical clustering on a matrix of data. How can I then plot the data as a matrix where the rows have been reordered to reflect a clustering induced by the cutting the dendrogram at a particular threshold, and have the dendrogram plotted alongside the matrix? I know how to plot the dendrogram in scipy, but not how to plot the intensity matrix of data with the right scale bar next to it. Any help on this would be greatly appreciated.

• Is using value converters to generate GUI-friendly strings a misuse of value converters?

  - by tempy

  Currently, I use value converters to generate user-friendly strings for the GUI. As an example, I have a window that displays the number of available entities in the status bar. The Viewmodel simply has an int dependency property that the calling code can set, and then on the binding for the textbox that displays the number of entities, I specify the int dependency property and a value converter that changes "x" into "x entities available". My code is starting to become littered with these converters, and I have a large number of annoying resource declarations in my XAML, and yet I like them because all the GUI-specific string formatting is being isolated in the converters and the calling code doesn't have to worry about it. But still, I wonder if this is not the purpose that value converters were made for.

• Visual Web Developer 2005 Express loads very slowly

  - by d03boy

  I admit that I am not a guru of Visual Studio products at all. I am using Visual Web Developer 2005 Express Edition and I'm trying to load someone else's project. This project happens to be a website with many pages. After loading VWD, it asks for a project to open and I select the solution file. It then proceeds to take an extremely long time to load. The status bar indicates that references are being loaded, many of which are in the System.Web.* area it seems. It seems like it's going back and forth between some different packages. The loading time is upwards of 20 to 30 minutes or more. Some others have stated that their projects open fine when they go to File Open Website... and choose the project directory from there. Any ideas what the problem could be and how to fix it? Edit: It finally completed loading after an hour approximately.

• Installshield 2009 Premier Basic MSI: Not show a warning message window during uninstall

  - by Samir

  Installshield 2009 Premier Basic MSI: When I uninstall there is a Message Box saying that explorer has to be closed: [Title] My-Product-Name [List] Explorer [radio button 1, Selected by default] Automatically close applications and attempt to restart them after setup is complete [radio button 2] Do not close applications. (A Reboot will be required) [Ok Button] [Cancel Button] If I click OK [with radio button 1 selected] all opened folders are closed !!! How to get rid of this, I don't want any warning message box to show and not close explorer either? More info: I have a dll which is used to show explorer context menu with icons when we right click on any file/folder. This dll is registered during installation and unregistered during uninstall. When we uninstall WinRAR we don't see any such messages, do we?

• Triggering shouldStartLoadWithRequest with multiple window.location.href calls

  - by AlBeebe

  Im trying to pass multiple things from a webpage inside a UIWebView back to my iPhone app via the shouldStartLoadWithRequest method of the UIWebView. Basically my webpage calls window.location.href = "command://foo=bar" and i am able to intercept that in my app no problem. Now if i create a loop and do multiple window.location.href calls at once, then shouldStartLoadWithRequest only appears to get called on once and the call it gets is the very last firing of window.location.href at the end of the loop. The same thing happens with the webview for Android, only the last window.location.href gets processed.

• Right clicking on QHeaderView inside of QTreeView

  - by taynaron

  I've written a descendant of QTreeView with multiple columns. I want to create a popup menu that appears whe nthe user right-clicks over the column headers. I have tried catching signals from QTreeView for this, but QTreeView doesn't seem to emit signals on the headers. QTreeView.header() does. I therefore believe I must either: 1: connect one of QHeaderView's signals to a popup function - I have been unable to find a signal that is triggered on a single right click - I have tried sectionClicked, sectionHandleDoubleClicked, sectionDoubleClicked, sectionPressed (not surprised the double click functions didn't catch a single right click - but they do catch a double right click) self.header().sectionClicked.connect(self.headerMenu) self.header().sectionHandleDoubleClicked.connect(self.headerMenu) self.header().sectionDoubleClicked.connect(self.headerMenu) self.header().sectionPressed.connect(self.headerMenu) or, 2: write a descendant of QHeaderView with my own MousePressEvent function, and use that for my headers. I have so far been unsuccessful in connecting the new header class to the QTreeView descendant. I keep getting a Segmentation Fault on runtime, with no more explanation. #in DiceView's init, where DiceHeaders is the QHeaderView descendant self.setHeader(DiceHeaders()) Any ideas?

• "Method definition not in @implementation context"?

  I put this in X-code: - (void)viewDidLoad { [super viewDidLoad]; NSString *path = [[NSBundle mainBundle] pathForResource:@"DrinkArray" ofType:@"plist"]; NSMutableArray* tmpArray = [[NSMutableArray alloc] initWithContentsOfFile:path]; self.drinks = tmpArray; [tmpArray release]; // Uncomment the following line to display an Edit button in the navigation bar for this view controller. // self.navigationItem.rightBarButtonItem = self.editButtonItem; } And it says this on the first line: "Method Definition not an @implementation context" Could anyone help?

• jquery Cycle plugin conflicing with custom script

  - by jeerose

  I have a site in development here: http://bit.ly/diWSgT Scenario: My custom script looks at the viewport size and if the menu and logo are not in view, animates them up into view (just re-size your browser window to test if you like). That works fine. I also have the every wonderful jQuery cycle plugin in use via WP-Cycle for Wordpress. The problem: As you can see by checking out the site, using my slide up/down button buggers with the cycle function, particularly when you click the button while on the second image. Any thoughts as to why this is happening would be great. Thanks.

• Sharepoint - Navigation.QuickLaunch has missing items

  - by linqmonkey

  The following code generates an ASCII art tree view of a sharepoint site structure based on the items in the quick launch menu. But some are missing. From googling i've found suggestions that this may be because QuickLaunch only contains items that have been customised. Any idea how to fix this? I want to use the QuickLaunch items as many of the sites have subsites and pages that need to be displayed in a specific order. RecurseNavigation(SPWeb web) { depth++; foreach (SPNavigationNode node in web.Navigation.QuickLaunch) { Console.Write(new String('-', depth)); Console.WriteLine(node.Title + " ("+node.Url+")"); RecurseNavigation(root.OpenWeb(node.Url)); } depth--; }

• php cURL POST how to follow location

  - by webfac

  Hi Guys, I am in a bit of a rut with a cURL issue. The post works greate, the data is POSTED just fine and received ok, but the url of the posted page never appears in the browser after the cURL session is executed, for example look at the following code: $ch = curl_init("http://localhost/eterniti/cart-step-1.php"); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, "error=1&em=$em&fname=$fname&lname=$lname&email1=$email1&email2=$email2&code=$code&area=$area&number=$num&mobile=$mobile&address1=$address1&address2=$address2&address3=$address3&suburb=$suburb&postcode=$postcode&country=$country"); curl_exec($ch); curl_close($ch); The post works fine and I am taken to the cart-step-1.php where I can process the posted data, HOWEVER the location in the URL address bar of the browser remains that of the script page, in this case proc_xxxxxx.php Any ideas how to get the URL address to reflect the page I am actually POSTED to? Thanks a mill

• Checking for any lowercase letters in a string

  - by pcampbell

  Consider a JavaScript method that needs to check whether a given string is in all uppercase letters. The input strings are people's names. The current algorithm is to check for any lowercase letters. var check1 = "Jack Spratt"; var check2 = "BARBARA FOO-BAR"; var check3 = "JASON D'WIDGET"; var isUpper1 = HasLowercaseCharacters(check1); var isUpper2 = HasLowercaseCharacters(check2); var isUpper3 = HasLowercaseCharacters(check3); function HasLowercaseCharacters(string input) { //pattern for finding whether any lowercase alpha characters exist var allLowercase; return allLowercase.test(input); } Is a regex the best way to go here? What pattern would you use to determine whether a string has any lower case alpha characters?

• Securing Files over Web: Fine Grained Authorization Based File Access

  - by Nishant

  I have a system where employees can upload files. There are three ways Upload to my account in public, private or protected mode Upload to department account in public, private or protected mode Upload to organization account in public, private or protected mode where public is visible to anyone, private to the group or person only and protected to anyone in the organization. All the files for an organization are stored in a directory say, /files/<organizationId>/, on file server like files +-- 234809 | +img1.jpg | +doc1.pdf +-- 808234 | +doc2.pdf I am storing file-path and privacy level in DB. So, I can control whether to show link to a file URL to an user -- on a given page. The problem is, I do not have any control over file's URL... so, if some one types the URL to img1.jpg in his browser's address bar, there is no way to know whether a logged in user is eligible to see img1.jpg. Any suggestion? Thanks Nishant

• Iterator for boost::variant

  - by Ivan

  Hy there, I'm trying to adapt an existing code to boost::variant. The idea is to use boost::variant for a heterogeneous vector. The problem is that the rest of the code use iterators to access the elements of the vector. Is there a way to use the boost::variant with iterators? I've tried typedef boost::variant<Foo, Bar> Variant; std::vector<Variant> bag; std::vector<Variant>::iterator it; for(it= bag.begin(); it != bag.end(); ++it){ cout<<(*it)<<endl; } But it didn't work.

• WPF: KeyboardNavigationMode.Contained doesn't work to suppress focus wrap

  - by codymanix

  I want to navigate in my window with the arrow key. It works so far but if I reach the end of my window, focus wraps to the first main menu item. But I want that focus stops at the last control in my window. private void Window_PreviewKeyDown(object sender, KeyEventArgs e) { if (e.Key == Key.Down) { elem.MoveFocus(FocusNavigationDirection.Next); } } "elem" is indirect child control of "stackPanel". MoveFocus always returns true and I already tried: KeyboardNavigation.SetTabNavigation(stackPanel, KeyboardNavigationMode.Contained); KeyboardNavigation.SetDirectionalNavigation(stackPanel,KeyboardNavigationMode.Contained); KeyboardNavigation.SetControlTabNavigation(stackPanel, KeyboardNavigationMode.Contained); Nothing helped.

• DRUPAL: Spamspan module... how does it work ?

  - by Patrick

  hi, I've installed http://drupal.org/project/spamspan module for Drupal (drupal.org/project/spamspan), in order to obfuscate the e-mail addresses on my website. However I'm not sure it is working. I can see the email url from source html and I think the module is not filtering anything. I've added some e-mails in the text editor CKEditor. Is it automatically detecting these emails written in text editor ? I haven't find any settings menu, after I installed the module. I guess there is not. thanks

• Sound not working in iPhone Simulator?

  - by pix0r

  Somehow my iPhone Simulator is unable to play sounds. First an app I'm working on using AudioServicesPlaySystemSound() stopped working.. I spent a while debugging this but sound is still working on the iPhone when I run the app on the device. I get the same results with other iPhone apps such as the sample Crash Landing app. I can't find a sound setting anywhere in the simulator or Xcode preferences. I've tried resetting the simulator through "Reset Content and Settings" menu item to no avail.

• Jquery AJAX and figuring out how NOT to nest callbacks for multiple reloads.

  - by David H

  I have a site with a few containers that need to load content dynamically via AJAX. Most of the links inside of the containers actually load new data in that same container. I.E: $("#navmenu_item1").click(function() { $("#navmenu").load(blah); }); When I click on a link, lets say "logout," and the menu reloads with the updated login status, none of the links now work because I would need to add a new .click into the callback code. Now with repeated clicks and AJAX requests I am not sure how to move forward from here, as I am sure nested callbacks are not optimal. What would be the best way to do this? Do I include the .click event inside the actual AJAX file being pulled from the server, instead of within index.php? Or can I somehow reload the DOM? Thanks for the help!

• Adding js to a drupal node form

  - by googletorp

  In Drupal you can create your own nodetype in a custom module. Doing this you get to create your own form which is all very nice. However if you want to add js the form things get a bit more tricky. If you add the js in the form, the js will only be added form the form when it is loaded. If the user would post the form with validation errors, the form function is not run again and thus the js is not added. Normally you would just create a menu callback and add the js there, but for the node add form, this wont be a possible solution. So what is the best solution for adding js in a node add form, to keep it persistant when the form doesn't validate?

• Visual Studio Extensions

  - by John Maloney

  I have a project that generates text (representing an interface and a class) based on metadata. I would like to take this generated code and insert it as a new class and interface directly into the currently opened solution under a specific project and directory. I will create the menu tool that will generate the class but what I don't know how to do is gain access to the following items from within my custom Visual Studio Extension: Iterate the current solution and find a project to dump the generated code into. Open a new file window within Visual Studio and inject the generated text that comes from my tool directly into that window. Create a new folder in a specific project within the current solution from within my custom extension. EDIT - To clarify I need to open a new file (e.g. Right Click on a Project - Add - New Class) and insert text into it from within my custom Visual Studio Extension. Thanks

• Cut and paste out of/ into text fields in a separate window doesn't work

  - by Brian Postow

  I have a Macintosh Mozilla plugin which puts up a separate window for login information. It seems to work fine, it gets keyboard events like typing and hitting return to hit the default button. HOWEVER, it doesn't seem to get cut and paste events. When I hit Cmd-v, the edit menu flashes, but nothing happnes. Is this a problem with my responder chain? Do I have to specially tell Mozilla that I want these events? or am I likely to have some other problem that I haven't even thought of? thanks.
