  • Change the height of a list item when it's in edit mode

    - by toby
    I have custom list item renderers and editors for a List control. I need for the editor to have a greater height then the renderer, i.e., the row should expand(in height) when it goes into edit mode. However, even when the list's variableRowHeight is set to true, it doesn't do what I want: the height seems to be based on the height of the renderer only, not the editor. Is there any way to do what I want?

  • CODE1 at SPOJ - cannot solve it

    - by VaioIsBorn
    I am trying to solve the problem Secret Code on SPOJ, and it's obviously a math problem. The full problem For those who are lazy to go and read, it's like this: a0, a1, a2, ..., an - sequence of N numbers B - a Complex Number (has both real and imaginary components) X = a0 + a1*B + a2*(B^2) + a3*(B^3) + ... + an*(B^n) So if you are given B and X, you should find a0, a1, ..an. I don't know how or where to start, because not even N is known, just X and B. The problem is not as easy as expressing a number in a base B, because B is a complex number. How can it be solved?

  • How to run unit tests in STAThread mode?

    - by Peter
    I would like to test an app that uses the Clipboard (WindowsForms) and I need the Clipboard in my Unittests also. In order to use it, it should run in STA mode, but since the NUnit Testfixture does not have a main method, I don't know where/how to annotate it... Thanks!

  • 3D effect to distort paper

    - by donpal
    This may be a little hard to describe since I don't have a sample. I'm trying to find a math function or full 3d function in php or a similar language that can help me with the following effect: imagine if you were to take a flat sheet or paper and glue it on a glass of water. It wouldn't be flat any more. It would have a curve, and one of its sides might end up being slightly hidden. Anyone can refer me to a good library or resource on the web where such functions can be found?

  • Are all the system's floating points operations the same?

    - by Jj
    We're making this web app in PHP and when working in the reports we have Excel files to compare our results to make sure our coding is doing the right operations. Now we're running into some differences due floating point arithmetics. We're doing the same divisions and multiplications and running into slightly different numbers, that add up to a notable difference. My question is if Excel is delegating it's floating point arithmetic to the CPU and PHP is also relying in the CPU for it's operations. Or does each application implements its own set of math algorithms?

  • UITableView : detecting click on '-' button in edit mode

    - by synthez84
    Hi all, On my iphone app, I have a UITableView in edit mode, containing custom UITableViewCell. I would like to detect when user has clicked on the left button of each cell (minus circular red button, the one that is animated with a rotation), just before the "Delete" button appears. I would like to be able to change my cell content in that case... Is that possible ? Thanks !

  • The action or event has been blocked by Disabled Mode

    - by mattruma
    I am using Microsoft Access 2007 to move and massage some data between two SQL Servers. Yesterday everything was working correctly, I was able to run queries, update data, and delete data. Today I opened up the Access database to finish my data migration and am now receiving the following message when I try to run some update queries: The action or event has been blocked by Disabled Mode. Any ideas what this is talking about?

  • Explicitly multiplying values as longs

    - by Bill Szerdy
    I understand that all math is done as the largest data type required to handle the current values but when you transverse a loop how do you explicitly multiply longs? The following code returns 0, I suspect, because of an overflow. long result = 0L; List<Long> temp = (List<Long>) getListOfIntegers(); for (int i = 0; i < temp.size(); i++) { result *= temp.get(i).longValue(); } System.out.println(result);

  • What's a better choice for SQL-backed number crunching - Ruby 1.9, Python 2, Python 3, or PHP 5.3?

    - by Ivan
    Crterias of 'better': fast im math and simple (little of fields, many records) db transactions, convenient to develop/read/extend, flexible, connectible. The task is to use a common web development scripting language to process and calculate long time series and multidimensional surfaces (mostly selectint/inserting sets of floats and dong maths with rhem). The choice is Ruby 1.9, Python 2, Python 3, PHP 5.3, Perl 5.12, JavaScript (node.js). All the data is to be stored in a relational database (due to its heavily multidimensional nature), all the communication with outer world is to be done by means of web services.

  • How do you create a formula that has diminishing returns?

    - by egervari
    I guess this is a math question and not a programming question, but what is a good way to create a formula that has diminishing returns? Here are some example points on how I want the curve to look like. f(1) = 1 f(1.5)= .98 f(2) = .95 f(2.5) = .9 f(3) = .8 f(4) = .7 f(5) = .6 f(10) = .5 f(20) = .25 Notice that as the input gets higher, the percentage decreases rapidly. Is there any way to model a function that has a very smooth and accurate curve that says this? Another way to say it is by using a real example. You know in Diablo II they have Magic Find? There are diminishing returns for magic find. If you get 100%, the real magic find is still 100%. But the more get, your actual magic find goes down. So much that say if you had 1200, your real magic find is probably 450%. So they have a function like: actualMagicFind(magicFind) = // some way to reduced magic find

  • How to replicate PS multiply layer mode

    - by Andrew Philpott
    Does anybody know of a good way to replicate Photoshop's multiply layer mode using either an image or CSS? I'm working on a project that has thumbnails that get a color overlay when you hover over them, but the designer used a layer set to multiply and I can't figure out how to produce it on the web. The best thing I've come up with is either using rgba or a transparent png, but even then it doesn't look right.

  • Calculate proportional width of object (proportion: 1600x1080)

    - by Hans Stauden
    Hello, this jquery question: when I set a specific height to a "#div", i want to set the width of a inner object automatically too (cause i need a width to read it out) [ "#div" ["object"] ] example: (object).css(width: [ CALCULATION ], height: ($("#div").height())+'px' ) the original proportion of the image is: 1600x1080 here's the link to the attachment, take a look at it (tinypic): link text the heights "500px", "600px" and "700px" you can see in the attachment are just examples, the heigth could also be "711px", "623px", "998px" etc. cause the "#div" scales with the browser (i can read out the height of window, that works) my math skills aren't really good, would be great if someone could help me out :-)

  • Re-Add tabBarController's view into window and the device is in landscape mode

    - by user285553
    Hello, I have an app that is a tabBarController based app. I have 4 tabs on it and one of these is for logging in/out in my app. The main ideea is that when I logout, I release the tabBarController (this will release the all 4 view controllers too - I have done this becuse I want to refersh all the views after logging out to look just like the first time).After this, I alloc it again and add the view controllers aagin,set the tabBarItem's titles,etc.This work ok. The problem is when I am in landscape mode;my logout view is painted to fit the landscape area,but after disconnect(now I releasse and alloc again the tabbarController) the view is painted in portrait mode but my device is in lanscape. After disconnected, I call the releaseOldTabView and the createNewTabView.After this tabBarController is in portrait insead of landscape. -(void)releaseOldTabView:(BOOL)tabViewEnabled{ if(tabViewEnabled){ [tabBarController.view removeFromSuperview]; [tabBarController release]; } } -(void)createNewTabView{ tabBarController = [[UITabBarController alloc] init]; NSMutableArray *oneArray = [[NSMutableArray alloc] init]; tabBarController.delegate = self; LoginViewController *login= [[LoginViewController2 alloc] initWithNibName:@"LoginViewController" bundle:nil]; SecondViewController *secondController = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil]; ThirdViewController *thirdController = [[ThirdViewController alloc] init]; FourthViewController *fourthController = [[FourthViewController alloc] init]; login.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"Login" image:[UIImage imageNamed:@"connect.png"] tag:0]; secondController.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"TabBar2" image:[UIImage imageNamed:@"tabBar2.png"] tag:1]; thirdController.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"TabBar3" image:[UIImage imageNamed:@"tabBar3.png"] tag:2]; fourthController.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"TabBar4" image:[UIImage imageNamed:@"tabBar4.png"] tag:3]; [oneArray addObject:login]; [oneArray addObject:secondController]; [oneArray addObject:thirdController]; [oneArray addObject:fourthController]; [tabBarController setViewControllers:oneArray]; //[tabBarController.view convertRect:tabBarController.view.frame toView:window]; [window addSubview:tabBarController.view]; [oneArray release]; [login release]; [secondController release]; [thirdController release]; [fourthController release]; } After calling this method, the tabbar view is in portrait,but statusBar(the top bar which says the carrier name) is painted normally(landscape). I also tried the [tabBarController.view convertRect:tabBarController.view.frame toView:window]; but without any succes. Can anyone give a hand of help? Thanks in advance, Alex.

  • Obtain Latitude and Longitude from a GeoTIFF File

    - by Mikee
    Using GDAL in Python, how do you get the latitude and longitude of a GeoTIFF file? GeoTIFF's do not appear to store any coordinate information. Instead, they store the XY Origin coordinates. However, the XY coordinates do not provide the latitude and longitude of the top left corner and bottom left corner. It appears I will need to do some math to solve this problem, but I don't have a clue on where to start. What procedure is required to have this performed? I know that the GetGeoTransform() method is important for this, however, I don't know what to do with it from there.
