  • Providing lat/long AND title in iOS Maps URL seems to cause zoom level to be ignored

    - by Ian Howson
    I'm writing an iOS app that shows a location in Maps upon a user action. I'd like to drop a pin with a description and zoom in to show map detail. If I invoke Maps with the url http://maps.google.com/maps?q=-33.895851,151.18483+(Some+Description)&z=19 I get a pin with 'Some Description', but the zoom level is ignored. This does work on the Google Maps website. If I use http://maps.google.com/maps?q=-33.895851,151.18483&z=19 the zoom works, but I get no pin. I've tried a few combinations of ?q=, ?ll= and ?sll=, but so far, nothing will change zoom and show a description. Any clues? Just so we're really clear, here are some screenshots. I want this to work on a real device (i.e. with iOS Maps). The simulator uses Google Maps through Safari. Here's what I see with URL 1 ([[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://maps.google.com/maps?q=-33.895851,151.18483+(Some+Description)&z=19"]];) This is URL 2 ([[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://maps.google.com/maps?q=-33.895851,151.18483&z=19"]];): This is relikd's suggestion ([[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://maps.google.com/maps?z=19&q=-33.895851,151.18483+(Some+Description)"]];): I want the image I see in screenshot 2, but with a pin and a description.

  • Unit testing authorization in a Pylons app fails; cookies aren't been correctly set or recorded

    - by Ian Stevens
    I'm having an issue running unit tests for authorization in a Pylons app. It appears as though certain cookies set in the test case may not be correctly written or parsed. Cookies work fine when hitting the app with a browser. Here is my test case inside a paste-generated TestController: def test_good_login(self): r = self.app.post('/dologin', params={'login': self.user['username'], 'password': self.password}) r = r.follow() # Should only be one redirect to root assert 'http://localhost/' == r.request.url assert 'Dashboard' in r This is supposed to test that a login of an existing account forwards the user to the dashboard page. Instead, what happens is that the user is redirected back to the login. The first POST works, sets the user in the session and returns cookies. Although those cookies are sent in the follow request, they don't seem to be correctly parsed. I start by setting a breakpoint at the beginning of the above method and see what the login response returns: > nosetests --pdb --pdb-failure -s foo.tests.functional.test_account:TestMainController.test_good_login Running setup_config() from foo.websetup > /Users/istevens/dev/foo/foo/tests/functional/test_account.py(33)test_good_login() -> r = self.app.post('/dologin', params={'login': self.user['username'], 'password': self.password}) (Pdb) n > /Users/istevens/dev/foo/foo/tests/functional/test_account.py(34)test_good_login() -> r = r.follow() # Should only be one redirect to root (Pdb) p r.cookies_set {'auth_tkt': '"4c898eb72f7ad38551eb11e1936303374bd871934bd871833d19ad8a79000000!"'} (Pdb) p r.request.environ['REMOTE_USER'] '4bd871833d19ad8a79000000' (Pdb) p r.headers['Location'] 'http://localhost/?__logins=0' A session appears to be created and a cookie sent back. The browser is redirected to the root, not the login, which also indicates a successful login. If I step past the follow(), I get: > /Users/istevens/dev/foo/foo/tests/functional/test_account.py(35)test_good_login() -> assert 'http://localhost/' == r.request.url (Pdb) p r.request.headers {'Host': 'localhost:80', 'Cookie': 'auth_tkt=""\\"4c898eb72f7ad38551eb11e1936303374bd871934bd871833d19ad8a79000000!\\"""; '} (Pdb) p r.request.environ['REMOTE_USER'] *** KeyError: KeyError('REMOTE_USER',) (Pdb) p r.request.environ['HTTP_COOKIE'] 'auth_tkt=""\\"4c898eb72f7ad38551eb11e1936303374bd871934bd871833d19ad8a79000000!\\"""; ' (Pdb) p r.request.cookies {'auth_tkt': ''} (Pdb) p r <302 Found text/html location: http://localhost/login?__logins=1&came_from=http%3A%2F%2Flocalhost%2F body='302 Found...y. '/149> This indicates to me that the cookie was passed in on the request, although with dubious escaping. The environ appears to be without the session created on the prior request. The cookie has been copied to the environ from the headers, but the cookies in the request seems incorrectly set. Lastly, the user is redirected to the login page, indicating that the user isn't logged in. Authorization in the app is done via repoze.who and repoze.who.plugins.ldap with repoze.who_friendlyform performing the challenge. I'm using the stock tests.TestController created by paste: class TestController(TestCase): def __init__(self, *args, **kwargs): if pylons.test.pylonsapp: wsgiapp = pylons.test.pylonsapp else: wsgiapp = loadapp('config:%s' % config['__file__']) self.app = TestApp(wsgiapp) url._push_object(URLGenerator(config['routes.map'], environ)) TestCase.__init__(self, *args, **kwargs) That's a webtest.TestApp, by the way. The encoding of the cookie is done in webtest.TestApp using Cookie: >>> from Cookie import _quote >>> _quote('"84533cf9f661f97239208fb844a09a6d4bd8552d4bd8550c3d19ad8339000000!"') '"\\"84533cf9f661f97239208fb844a09a6d4bd8552d4bd8550c3d19ad8339000000!\\""' I trust that that's correct. My guess is that something on the response side is incorrectly parsing the cookie data into cookies in the server-side request. But what? Any ideas?

  • Transactional NTFS (TxF) on Process.Start()

    - by Ian
    Consider the following code: try { using(TransactionScope) { Process.Start("SQLInstaller.EXE"); throw new Exception(); Commit(); } } catch(Exception ex) { //Do something here } Will the changes made by SQLInstaller.exe be rollback in this scenario? More specifically, will the changes made by an external process launched through Process.Start() be handled by TxF? Thanks!

  • XSLT: Transforming into non-xml content?

    - by Ian Boyd
    Is it possible to use XSLT to transform XML into something other than XML? e.g. i want the final non-xml content: <HTML> <BODY> <IMG src="file1.png"><BR> <IMG src="file2.png"><BR> ... <IMG src="filen.png"><BR> </BODY> </HTML> You'll notice this document is HTML, because in HTML IMG and BR tags are forbidden from having a closing tag. This constrasts with xhtml, the reformulation of HTML using xml, where all elements are required from having a closing tag (because in xml every tag must be closed). Is it possible, using XSLT, to generate non-xml output? Another example of non-xml output might be: INSERT INTO Documents (Filename) VALUES ('file1.png') INSERT INTO Documents (Filename) VALUES ('file2.png') ... INSERT INTO Documents (Filename) VALUES ('file3.png') The reason i ask is that as soon as my XSLT contains an <IMG>, the stylesheet contains an error; no closing </IMG>.

  • UITableView with dynamic cell heights -- what do I need to do to fix scrolling down?

    - by Ian Terrell
    I am building a teensy tiny little Twitter client on the iPhone. Naturally, I'm displaying the tweets in a UITableView, and they are of course of varying lengths. I'm dynamically changing the height of the cell based on the text quite fine: - (CGFloat)heightForTweetCellWithString:(NSString *)text { CGFloat height = Buffer + [text sizeWithFont:Font constrainedToSize:Size lineBreakMode:LineBreakMode].height; return MAX(height, MinHeight); } - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { NSString *text = // get tweet text for this indexpath return [self heightForTweetCellWithString:text]; } } I'm displaying the actual tweet cell using the algorithm in the PragProg book: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"TweetCell"; TweetCell *cell = (TweetCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [self createNewTweetCellFromNib]; } cell.tweet.text = // tweet text // set other labels, etc return cell; } When I boot up, all the tweets visible display just fine. However, when I scroll down, the tweets below are quite mussed up -- it appears that once a cell has scrolled off the screen, the cell height for the one above it gets resized to be larger than it should be, and obscures part of the cell below it. When the cell reaches the top of the view, it resets itself and renders properly. Scrolling up presents no difficulties. Here is a video that shows this in action: http://screencast.com/t/rqwD9tpdltd I've tried quite a bit already: resizing the cell's frame on creation, using different identifiers for cells with different heights (i.e. [NSString stringWithFormat:@"Identifier%d", rowHeight]), changing properties in Interface Builder... If there are additional code snippets I can post, please let me know. Thanks in advance for your help!

  • Signed and RequireAdministrator manifested executable being run from temp folder?

    - by Ian Boyd
    i manifested my executable as require administrator: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <!-- Disable Windows Vista UAC compatability heuristics --> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2"> <security> <requestedPrivileges> <requestedExecutionLevel level="requireAdministrator"/> </requestedPrivileges> </security> </trustInfo> </assembly> And then i digitally signed it. But then when i run the executable i noticed something odd: the name of the executable on the Consent dialog changed from PingWarning.exe to pinxxxx.tmp; as though a temp copy was made, and that is being run: i dug out Process Montior, to see if anyone is creating a *.tmp file when i launch my executable, and there is: The Application Information service inside this particular svchost container is intentionally copying my executable to the Windows temp folder, and asking for user "Consent" from there; giving an invalid filename. Once consent has been granted, the executable is run from its original location: link text The file is not copied to the temp folder if i do not digitally sign it: So my problem is the invalid filename appearing on the consent dialog when i digitally sign my executable which has been manifested as requireAdministrator. What do?

  • Uninstalling demo/trial of Visual Studio 2008 Team System

    - by Ian Ringrose
    I wish to uninstall the trail copy of VS 2008 Team System, as the trial is coming to its end. I had VS 2008 Professional Edition installed on the machine to start with and it still shows up in Add/Remove Problems. I am hoping that when I uninstall VS 2008 Team System I will be left with a working VS 2008 Professional Edition. When I try to uninstall VS 2008 Team System, I very quickly get an error dialog that says: A problem has been encountered while loading the setup components. Canceling setup. Help! Progress or lack there of so fare I have done dir %temp%*.log in a command prompt and can see any log files that are recent I am going to read http://en.wikipedia.org/wiki/Windows_Installer#Diagnostic_logging to see if I can get any logging Aaron Stebner's WebLog has a post on where VS put's is log files, he also has a post on were some other products put there log files gives some info about where VS setup puts it's logs etc Aaron Ruckman provided me with the solution after I sent him the log files.

  • Possible to get the line number of the currently executing sproc in SQL Server?

    - by Ian Kemp
    A few years back I worked in a Sybase/Delphi environment, using the BDE to connect to the DB server. We had a little Delphi app that, given the name of a currently executing stored procedure, could tell you what line of that sproc was currently being executed. This was exceptionally useful for debugging sprocs that seemed to be hanging. I'd like to use this functionality in SQL Server, but I can't remember whether it was a Sybase or a BDE feature. Is this functionality available in SQL Server and if so, what command(s) do I need to use to view this information?

  • Automatically number items in a wpf listbox

    - by evan
    I have a person class with two properties, Name an Age. I know how to use databinding to display a collection of person in a wpf list box and how to modify the listitemtemplate to customize how each person is displayed. Now I'd like to number each person on the list according to the order they appear on the list (which could change as the the items were sorted via name or age in the display). Is there a way to do that with the item template so instead of having a list like Rob - 14 John - 56 Suzy - 32 it would be 1) Rob - 14 2) John - 56 3) Suzy - 32 Basically i'd like to do something like: <ListView.ItemTemplate> <DataTemplate> <WrapPanel> **<TextBlock Text="{Binding CurrentPositionInList}" />** <TextBlock Text="{Binding Path=Name}" /> <TextBlock Text="{Binding Path=Age}" /> </WrapPanel> </DataTemplate> Thanks in advance!

  • PHP - Frameworks, ORM, Encapsulation.

    - by Ian
    Programming languages/environments aside, are there many developers who are using a framework in PHP, ORM and still abide by encapsulation for the DAL/BLL? I'm managing a team of a few developers and am finding that most of the frameworks require me to do daily code inspection because my developers are using the built in ORM. Right now, I've been using a tool to generate the classes and CRUD myself, with an area for them to write additional queries/functions. What's been happening though, is they are creating vulnerabilities by not doing proper checks on data permission, or allowing the key fields to be manipulated in the form. Any suggestions, other than get a new team and a new language (I've seen Python/Ruby frameworks have the same issues).

  • [Design Question] When to open a link on a new window?

    - by Ian
    Hi All, When designing a web application/web site, is there an accepted practice on when to open a link on a new window? Currently, if the site being linked to is outside the domain (say Google.com), I am always launching it on a new window. If the page being linked is within the same domain, I open it on the current active window. I've read somewhere the opening links on a new window explicitly is being frowned upon. Thanks!

  • How can I capture a multiline pattern using a regular expressions in java?

    - by lampShade
    I have a text file that I need to parse using regular expressions. The text that I need to capture is in multiline groups like this: truck zDoug Doug's house (123) 456-7890 [email protected] 30 61234.56 8/10/2003 vehicle eRob Rob's house (987) 654-3210 [email protected] For this example I need to capture truck followed by the next seven lines.In other words, in this "block" I have 8 groups. This is what I've tried but it will not capture the next line: (truck)\n(\w). NOTE: I'm using the program RegExr to test my regex before I port it to Java.

  • MySQL Locking Up

    - by Ian
    I've got a innodb table that gets a lot of reads and almost no writes (like, 1 write for every 400,000 reads approx). I'm running into a pretty big problem though when I do INSERT into the table. MySQL completely locks up. It uses 100% cpu, and every single other table (in other databases even) have their statuses set to "Locked" until the INSERT is done. This is a big problem because MySQL stays locked up for up to 4 minutes. I'm using version 5.1.47 (rpm from mysql.com). Any ideas?

  • Thread management advice - Is TPL a good idea?

    - by Ian
    I'm hoping to get some advice on the use of thread managment and hopefully the task parallel library, because I'm not sure I've been going down the correct route. Probably best is that I give an outline of what I'm trying to do. Given a Problem I need to generate a Solution using a heuristic based algorithm. I start of by calculating a base solution, this operation I don't think can be parallelised so we don't need to worry about. Once the inital solution has been generated, I want to trigger n threads, which attempt to find a better solution. These threads need to do a couple of things: They need to be initalized with a different 'optimization metric'. In other words they are attempting to optimize different things, with a precedence level set within code. This means they all run slightly different calculation engines. I'm not sure if I can do this with the TPL.. If one of the threads finds a better solution that the currently best known solution (which needs to be shared across all threads) then it needs to update the best solution, and force a number of other threads to restart (again this depends on precedence levels of the optimization metrics). I may also wish to combine certain calculations across threads (e.g. keep a union of probabilities for a certain approach to the problem). This is probably more optional though. The whole system needs to be thread safe obviously and I want it to be running as fast as possible. I tried quite an implementation that involved managing my own threads and shutting them down etc, but it started getting quite complicated, and I'm now wondering if the TPL might be better. I'm wondering if anyone can offer any general guidance? Thanks...

  • Python modules not updating after restarting the main module.

    - by Ian
    I've recently come back to a project having had to stop for about 6 months, and after reinstalling my operating system and coming back to it I'm having all kinds of crazy things happen. I made sure to install the same version(2.6) of python that I was using before. It started by giving me strange tkinter error that I hadn't had trouble with before, the program is relatively simple and the 2 or 3 bugs that were left when i quit, I had documented and weren't related to the interface. Things got even weirder when the same error would pop up even after I had removed the offending section of code. In fact, the traceback pointed to a line that didn't even exist in the module it was referencing, eg: line 262 when the module was only 200 lines long. After just starting a completely new file for the main module and copy/pasting it finally recognized that the offending code was gone and I stopped getting the error only to find that any updates to the code I made in another module didn't show up when I restarted the program through the shell. (I didn't forget to save.) After fiddling with this, of course, the old interface error came back, only in a different section of code that had been working previously. In fact, if I revert back to the files I had six months ago, the program works fine. As soon as I change anything in the main module, however, the interface bug comes back. Here's the original error: Exception in Tkinter callback Traceback (most recent call last): File "C:\Python26\lib\lib-tk\Tkinter.py", line 1410, in __call__ return self.func(*args) File "C:\PyStuff\interface.py", line 202, in dispOne __main__.top.destroy() File "C:\Python26\lib\lib-tk\Tkinter.py", line 1938, in destroy self.tk.call('destroy', self._w) TclError: can't invoke "destroy" command: application has been destroyed I'm guessing something else is going on here other than my own poor programming. Anyone have any ideas?

  • What is it about Fibonacci numbers?

    - by Ian Bishop
    Fibonacci numbers have become a popular introduction to recursion for Computer Science students and there's a strong argument that they persist within nature. For these reasons, many of us are familiar with them. They also exist within Computer Science elsewhere too; in surprisingly efficient data structures and algorithms based upon the sequence. There are two main examples that come to mind: Fibonacci heaps which have better amortized running time than binomial heaps. Fibonacci search which shares O(log N) running time with binary search on an ordered array. Is there some special property of these numbers that gives them an advantage over other numerical sequences? Is it a density quality? What other possible applications could they have? It seems strange to me as there are many natural number sequences that occur in other recursive problems, but I've never seen a Catalan heap.

  • Dynamic positioning inside relative div

    - by ian
    I'm trying to get a color picker javascript widget working in a page with a bunch of "stuff" in it that I can't change. Some of the "stuff" is causing the color picker to appear well below the link when clicked. I've reduced it to a simple example below. <html> <head> <script type="text/javascript"> function setPos(aname,dname) { var o=document.getElementById(aname); var ol=o.offsetLeft; while ((o=o.offsetParent) != null) { ol += o.offsetLeft; } o=document.getElementById(aname); var ot=o.offsetTop + 25; while((o=o.offsetParent) != null) { ot += o.offsetTop; } document.getElementById(dname).style.left = ol + "px"; document.getElementById(dname).style.top = ot + "px"; } </script> <style> h1 {height: 50px;} #divMain {position: relative;} </style> </head> <body> <h1></h1> <div id="divMain"> <a href="#" onClick="setPos('link1','div1');return false;" name="link1" id="link1">link 1</a> <div id="div1" style="position:absolute;border-style:solid;left:200px;top:200px;">div 1</div> </div> </body> </html> What's supposed to happen is when you click "link 1", "div1" should move directly below "link 1". What actually happens is that "div 1" appears well below "link 1". If you remove position: relative; from the CSS definition for divMain, "div 1" is positioned correctly. How can I position "div 1" directly beneath "link 1" without removing position: relative;?

  • Visual Studio Config File Editor - Not Formatting

    Hi All, My VS 2008 seems to be acting a bit weird and the solution is eluding me. The problem is that if I open a config file; app.config or web.config, this looks and behaves as a plain text document. I have no formatting, no coloring, no intellisense and no collapsible or expandable regions. I have reset all setting and restored default file associations. If I go into the setting menu, Text Editor, XML, formatting I see an error "An error occurred loading this property page" Has any one seen this before and have you go a solution. Thanks

  • Accessing localhost via IIS 6.1 on Windows 7 very slow

    - by Ian Devlin
    (I've checked here already for similiar questions, and haven't found one that's exactly the same - hence I'm posting a new question) I'm currently running an ASP.NET application on IIS 7.0 on Windows 7. When I access this application on Internet Explorer (either 6, 7 or 8) it is incredible slow and often fails to load at all. There are messages at the bottom saying: Waiting for http://localhost/....... or sometimes waiting for about:blank (I've read that this can be a virus, but I've run all the usual checks and it's not). constantly, but it returns with the usual: "Internet Explorer cannot display the webpage" I've also tried this by using 127.0.0.1 and the machine name, with the same results. I've tried the same application on the latest Firefox, Safari, Chrome and Opera and they all work fine. I've also installed the same application on a Windows Server 2003 machine, and it all works fine via Internet Explorer. Soes anyone have any ideas why this doesn't work with Internet Explorer and yet does with other browsers?

  • Drupal and Login Toboggan -- infinite redirect loop

    - by Ian Silber
    I'm getting a redirect loop when using Login Toboggan. It doesn't happen all of the time and I think I've narrowed it down to something with the session, specifically the active-tabs[last-active-href] value. Since it's intermittent, I was able to print out a session of a working copy and a non-working copy. Here are both: WORKS -- Array ( [active-tabs] = Array ( [last-active-href] = index ) ) toboggan/denied DOESN'T WORK -- Array ( [active-tabs] = Array ( [last-active-href] = user/register [user] = user/register ) [wantsEvents] = [wantsResources] = [wantsSupport] = ) toboggan/denied I've also noticed that if I comment out the following line the redirection loop stops (although no page loads): $return = menu_execute_active_handler('user/register'); Any ideas? I'm at my wits end.

    How do you change the font face and font size used by the Windows Ribbon Framwork? Background The user can configure Windows to use their preferred font size, e.g.: 8pt 9pt 12pt and their preferred font face, e.g.: MS Sans Serif Microsoft Sans Serif Tahoma Segoe UI Calibri but the Windows Ribbon Framework by default uses a font that is not the user's preference. Additionally, the user could have specified their font preference in my application, which i want the Ribbon hosted in my application to honor.
