  • UIAlertView won't rotate to landscape even with applicationDidFinishLaunching call

    - by Joey
    I am trying to use UIAlertView on my landscape right (home button on the right) app but it is showing up in portrait orientation. I have tried putting: [[UIApplication sharedApplication] setStatusBarOrientation: UIInterfaceOrientationLandscapeRight animated: NO ]; in applicationDidFinishLaunching, but it doesn't work. Are there any other usual suspects to what might be causing this? I am setting the orientation through my plist file currently.

  • Again, user config files C#

    - by George
    Hey guys. I have a large config file (user) that i needed to go to the right location and have some default values. Since i have a installer class, i added some parameter setting to the config file in it, but created the config files in the installers folder. What is the best way to ensure these default parameters will be written only once, and in the right location?

  • Turtle Graphics as a Haskell Monad

    - by iliis
    I'm trying to implement turtle graphis in Haskell. The goal is to be able to write a function like this: draw_something = do fordward 100 right 90 forward 100 ... and then have it produce a list of points (maybe with additional properties): > draw_something (0,0) 0 -- start at (0,0) facing east (0 degrees) [(0,0), (0,100), (-100,100), ...] I have all this working in a 'normal' way, but I fail to implement it as a Haskell Monad and use the do-notation. The basic code: data State a = State (a, a) a -- (x,y), angle deriving (Show, Eq) initstate :: State Float initstate = State (0.0,0.0) 0.0 -- constrain angles to 0 to 2*pi fmod :: Float -> Float fmod a | a >= 2*pi = fmod (a-2*pi) | a < 0 = fmod (a+2*pi) | otherwise = a forward :: Float -> State Float -> [State Float] forward d (State (x,y) angle) = [State (x + d * (sin angle), y + d * (cos angle)) angle] right :: Float -> State Float -> [State Float] right d (State pos angle) = [State pos (fmod (angle+d))] bind :: [State a] -> (State a -> [State a]) -> [State a] bind xs f = xs ++ (f (head $ reverse xs)) ret :: State a -> [State a] ret x = [x] With this I can now write > [initstate] `bind` (forward 100) `bind` (right (pi/2)) `bind` (forward 100) [State (0.0,0.0) 0.0,State (0.0,100.0) 0.0,State (0.0,100.0) 1.5707964,State (100.0,99.99999) 1.5707964] And get the expected result. However I fail to implement this as an instance of Monad. instance Monad [State] where ... results in `State' is not applied to enough type arguments Expected kind `*', but `State' has kind `* -> *' In the instance declaration for `Monad [State]' And if I wrap the list in a new object data StateList a = StateList [State a] instance Monad StateList where return x = StateList [x] I get Couldn't match type `a' with `State a' `a' is a rigid type variable bound by the type signature for return :: a -> StateList a at logo.hs:38:9 In the expression: x In the first argument of `StateList', namely `[x]' In the expression: StateList [x] I tried various other versions but I never got it to run as I'd like to. What am I doing wrong? What do I understand incorrectly?

  • Sysadmin 101: How can I figure out why my server crashes and monitor performance?

    - by bflora
    I have a Drupal-powered site that seems to have neverending performance problems. It was butt-slow about 5 months ago. I brought in some guys who installed nginx for anonymous visitors, ajaxified a few queries so they wouldn't fire during page load, and helped me find a few bottlenecks in the code. For about a month, the site was significantly faster, though not "fast" by any stretch of the word. Meanwhile, I'm now shelling out $400/month to Slicehost to host a site that gets less than 5,000/uniques a day. Yes, you read that right. Go Drupal. Recently the site started crashing again and is slow again. I can't afford to hire people to come in, study my code from top to bottom, and make changes that may or may not help anymore. And I can't afford to throw more hardware at the problem. So I need to figure out what the problem is myself. Questions: When apache crashes, is it possible to find out what caused it to crash? There has to be a way, right? If so, how can I do this? Is there software I can use that will tell me which process caused my server to die? (e.g. "Apache crashed because someone visited page X." or "Apache crashed because you were importing too many RSS items from feed X.") There's got to be a way to learn this, right? What's a good, noob-friendly way to monitor my current apache performance? My developer friends tell me to "just use Top, dude," but Top shows me a bunch of numbers without any context. I have no clue what qualifies as a bad number or a good number in Top, or which processes are relevant and which aren't. Are there any noob-friendly server monitoring tools out there? Ideally, I could have a page that would give me a color-coded indicator about how apache is performing and then show me a list of processes or pages that are sucking right now. This way, I could know when performance is bad and then what's causing it to be so bad. Why does PHP memory matter? My apparently has a 30MB memory foot print. Will it run faster if I bring that number down? Thanks for any advice. I spent a year or so trying to boost my advertising income so I could hire a contractor to solve my performance woes. I didn't want to have to learn all this sysadmin voodoo. I'm now resigned to the fact that might not have a choice.

  • Bitwise Operations -- Arithmetic Operations..

    - by RBA
    Hi, Can you please explain the below lines, with some good examples. A left arithmetic shift by n is equivalent to multiplying by 2n (provided the value does not overflow), while a right arithmetic shift by n of a two's complement value is equivalent to dividing by 2n(2 to the power n) and rounding toward negative infinity. If the binary number is treated as ones' complement, then the same right-shift operation results in division by 2n and rounding toward zero. Thankx..

  • How to call a JavaScript function from one frame to another in Chrome/Webkit with file protocol

    - by bambax
    I have developed an application that has a list of items in one frame; when one clicks on an item it does something in another frame (loads an image). This used to work fine in all browsers, including Chrome 3; now it still works fine in Firefox but in recent versions of Chrome (I believe since 4) it throws this error: Unsafe JavaScript attempt to access frame with URL (...) from frame with URL (...). Domains, protocols and ports must match. This is obviously a security "feature" but is it possible to get around it? Here is a simple test: index.html: <html> <frameset cols="50%,50%"> <frame src="left.html" name="left"/> <frame src="right.html" name="right"/> </frameset> </html> left.html: <html> <body> <a href="javascript:parent.right.test('hello');">click me</a> </body> </html> right.html: <html> <body> <script> function test(msg) { alert(msg); } </script> </body> </html> The above works in Firefox 3.6 and Chrome 3 but in Chrome 5 it throws the above error... Edit: added the @cols attribute to the frameset element in fact it works in Chrome if and only if the pages are served with the http protocol (and from the same domain) but my problem is when pages are local and served from a file:// protocol. Then it works in Firefox (all versions) and Chrome 3 but not Chrome 5 (I don't have Chrome 4 so I'm not shure about that specific version (and don't know if it's even possible to download a specific Chrome version?) -- but for Chrome 5 I'm very sure it doesn't work).

  • prgramming a windows service

    - by xarzu
    I have started prgramming a windows service. I have added a notify icon from the toolbox. It has the small notify icon that appears in the systray as a member of those icons. It works so far. So far I have a blank form. I have used the DoubleClick for the notifyIcon to bring up the form (I will use the form for something later). Now I have a list of things I want to accomplish to make this work like a true windows service. First of all, if possible, I owuld like to remove the maximize and cancel button on the form. Most windos service apps that I have seen offer the ability to close the app by right-mouse-button clicking on the notify icon which brings up a menu of options. I see in the properties of the form under Misc there is an CancelButton. But I do not see how do deactivate it. In the Properties of the forum I see under Window Style there is a ControlBox option that, if I turn to false, all three buttons, (minimize, maximize and cancel) go away. These are not what i am looking for. I would not like the option for them to resize, maximize or close the form here. I suspect people will close the box intending to make the box go away while still wanting the app to run. Under the "Focus" caption in Properties, there id "Deactivate". I have created my own event/method/function for this and in debug I noticed that when you click on the x-box in the upper right corner, this function is called. The problem is that after the function is over, the app closes anyway. How do I over-ride this function? Secondly, how do you catch the right button click event on the notify icon in the systray? I can see how to create events for "Click" and "MouseClick" etc. but how so I determine which button was click? Using the right buton click is how such programs know when to pull up a menu. So I would like to know how to do this as well.

  • What happened to the "Run" and "Run On" commands in Visual Studio 2010 Database Projects?

    - by Steve Elmer
    Hello, I have migrated a database project from VS2008 to VS2010. While in VS08, I used to be able to right-click on a .sql or .cmd file and select a "Run" or "Run On" command from the context menu. In VS2010, though, these menu items seem to have gone away. I have a number of .sql and .cmd scripts that I am used to being able to run directly from the Visual Studio IDE. Can someone point me in the right direction? Thanks, Steve

  • Ajax problem not displaying data using multiple javascript calls...

    - by Ronedog
    I'm writing an app that uses ajax to retrieve data from a mysql db using php. Because of the nature of the app, the user clicks an href link that has an "onclick" event used to call the javascript/ajax. I'm retrieving the data from mysql, then calling a separate php function which creates a small html table with the necessary data in it. The new table gets passed back to the responseText and is displayed inside a div tag. The tables only have around 10-20 rows of data in them. This functionality is working fine and displays the data in html form exactly as it needs to be on the page. The problem is this. the HREF "onclick" event needs to run multiple scripts one right after the other. The first script updates the "existing" data and inside the "update_existing" function is a call to refresh a section of the page with the updated HTML from the responseText. Then when that is done a "display_html" function is called which also updates a different section of the page with it's newly created HTML table. The event looks like this: Update This string gets built dynamically using php with parameters supplied, but for this example I simply took the parameters out so it didn't get confusing. The "update_existion() function actually calls the display_html() function which updates a section of the page as needed. I need to update a different section of the page on the same click of the mouse right after the update, which is why I'm calling the display_html() again, right after it. The problem is only the last call is being updated on my screen. In other words, the 2nd function call "display_html()" executes and displays the refreshed data just fine, but the previous call to update_existing() runs and updates the database properly, but doesn't display on the screen unless I press the browsers "refresh" button, which of course displays the new data exactly how I want it to, but I don't want the users to have to press the "refresh" button. I tried adding multiple "display_html() calls one right after the other, separating all of them with the semicolon and learned that only the very last function call actually refreshed the div element on the html page with the table information, although all the previous display_html() calls worked, they couldn't be seen on the page without a refresh of the browser. Is this a problem with javascript, or the ajax call, or is this a limitation in the DOM that only allows one element to be updated at a time. The ajax call is asynchroneous, but I've tried both, only async works period. This is the same in both Firefox and Internet Explorer Any ideas what's going on and how to get around it so I can run these multiple scripts?

  • Javascript ContextMenu on a TD

    If I attach a context menu to a td, it fires okay for text in the TD, but if I add a div to the TD, the context menu will not fire when right clicking on the div. How can I make the context menu fire when anything, data or divs, are right clicked in the td?

  • Gui's with Win32 API

    - by user146780
    I'm wondering what the correct way of creating Gui's in with Win32 API. Right now I just call the CreateWindowEx in my WM_CREATE event, but I don't think this is the right way to do it. Just as an example, what would be the correct way of adding a 100x20 EditField and getting text from it? Would you create it on WM_Create then use GetText()? Thanks

  • Sanitizing input for display in view when using simple_format

    - by Eric
    Hi, I'm trying to figure out the right way to display comments such that newlines and links are displayed. I know that usually, you should display user-inputs only when escaping html with h(). That of course won't display newlines or links, so I found the simple_format and auto_link methods. What I am now doing is: simple_format(santize(auto_link(comment.text))) Is this the right way to do this, and is it still safe from XSS attacks? Thanks! Eric

  • any ideas how to make checked treeview inside multiselect jqeury?

    i planned to make checked treeview inside a multiselect jquery. The left side was the checked treeview, if we choose the child, the one moving to the right side was the child and the parent title, and if we choose the parent, all of the child will be moving right. I found some of the example, but they're in vb, can jqeury make something like this?

  • iPhone platform: endianness (detection & swapping)

    - by quixoto
    Hi all, I'm doing some endian-sensitive file manipulation on iPhone. Are there standard macros or #defines in that environment that indicate native endianness and offer swapping if necessary? I know I can check in advance and just do the right thing for this particular architecture, but wondering if there are cleaner ways of doing the right thing. (The file format is little endian; if it were big-endian, I'd probably just use the htons/htonl family.) Thanks.

  • Reverting a single file to a previous version in git

    - by georgeliquor
    Is there a way to go through different commits on a file. Say I modified a file 5 times and I want to go back to change 2, after I already committed and pushed to a repository. In my understanding the only way is to keep many branches, have I got that right? If I'm right I'm gonna have hundreds of branches in a few days, so I'm probably not understanding it really. Could anyone clear that up please?

  • Choose variable based on users choice from picklist.

    - by Kelbizzle
    I have this form. Basically what I want is to send a auto-response with a different URL based on what the user picks in the "attn" picklist. I've been thinking I could have a different variable for each drop down value. It will then pass this variable on to the mail script that will choose which URL to insert inside the auto response that is sent. It gives me a headache thinking about it sometimes. What's the easiest way to accomplish this? Am I making more work for myself? I really don't know because I'm no programmer. Thanks in advance!

  • Is there an easy way to compare if 2 XDocuments are equal ignoring element/attribute order?

    - by Davy8
    Unit testing my serialization code I found one failed because I had attributes listed in a different order (I'm just comparing the XDocument.ToString() values) and while I could fix that, it really doesn't matter to me in what order the elements or attributes appear as long as they're all there with the right name at the right level of hierarchy. I could probably write a method do this, but I'm wondering if there's an easy built in way I'm not aware of.
