  • Click events not working in Rails view

    - by Fdr
    I have following view (html.erb): <h3>My view</h3> <script> function test() { alert("hello"); } </script> <input type="button" onClick="test();" value="test" /> For reasons I cannot understand the onClick event never gets fired when I access the view through rails(tried static apache hosting - no problems there). Here is rendered html: http://pastebin.com/LmGysgUG I feel quite stupid, is this something to do the way Rails renders views?

  • Add up values from a text file

    - by Stanley
    Hi Guys I have a text file that contains Amounts at Substring (34, 47) of each line. I need to sum Up all the Values to the End of the File. I have this code that I had started to build but I do not know how to proceed from here: public class Addup { /** * @param args the command line arguments */ public static void main(String[] args) throws FileNotFoundException, IOException { // TODO code application logic here FileInputStream fs = new FileInputStream("C:/Analysis/RL004.TXT"); BufferedReader br = new BufferedReader(new InputStreamReader(fs)); String line; while((line = br.readLine()) != null){ String num = line.substring(34, 47); double i = Double.parseDouble(num); System.out.println(i); } } } The output is like this: 1.44576457E4 2.33434354E6 4.56875685E3 The Amount is in two decimal Places and I need the result also in the Two decimal Places. What Is the Best way to achieve this?

  • Explicitly typing variables causes compiler to think an instance of a builtin type doesn't have a pr

    - by wallacoloo
    I narrowed the causes of an AS3 compiler error 1119 down to code that looks similar to this: var test_inst:Number = 2.953; trace(test_inst); trace(test_inst.constructor); I get the error "1119: Access of possibly undefined property constructor through a reference with static type Number." Now if I omit the variable's type, I don't get that error: var test_inst = 2.953; trace(test_inst); trace(test_inst.constructor); it produces the expected output: 2.953 [class Number] So what's the deal? I like explicitly typing variables, so is there any way to solve this error other than not providing the variable's type?

    - by Code Smack
    Hello, I am using VS 2008 C# Windows Application. I have this DLL Import I am trying to use. [DllImport("Mapi32.dll", PreserveSig = true)] private static extern void WrapCompressedRTFStream( [MarshalAs(UnmanagedType.Interface)] UCOMIStream lpCompressedRTFStream, uint ulflags, [MarshalAs(UnmanagedType.Interface)] out UCOMIStream lpUncompressedRTFStream ); public const uint MAPI_MODIFY = 0x00000001; public const uint STORE_UNCOMPRESSED_RTF = 0x00008000; I have a compressed string that is in CompressedRFTFormat. How do I pass the string into the WrapCompressedRTFStream? I do not understand what the method is expecting. I am trying to use it on a button. RichText1.text = WrapCompressedRTFStream(_CompressedRichText.ToString(),something,somethingelse); The first error I get is "cannot convert from 'string' to 'System.Runtime.InteropServices.UCOMIStream" I hope someone who understands this posts an answer that helps!

  • Downloading files in ASP.Net MVC web applications

    - by kingrichard2005
    Hello, I'm working on a project that requires the ability to let a user download a pdf from a static location on the server. I'm reading the instructions from this website, it's an old post and I notice they specify in an update that Microsoft's MVC framework has long since included and Action Result that allows the same functionality they discuss thus rendering it obsolete, I've looked a bit online but haven't been able to find any resources that discuss this built-in functionality. If anyone has any links or other information that discuss this it would be very helpful. Thanks.

  • Custom constructors for models in Google App Engine (python)

    - by Nikhil Chelliah
    I'm getting back to programming for Google App Engine and I've found, in old, unused code, instances in which I wrote constructors for models. It seems like a good idea, but there's no mention of it online and I can't test to see if it works. Here's a contrived example, with no error-checking, etc.: class Dog(db.Model): name = db.StringProperty(required=True) breeds = db.StringListProperty() age = db.IntegerProperty(default=0) def __init__(self, name, breed_list, **kwargs): db.Model.__init__(**kwargs) self.name = name self.breeds = breed_list.split() rufus = Dog('Rufus', 'spaniel terrier labrador') rufus.put() The **kwargs are passed on to the Model constructor in case the model is constructed with a specified parent or key_name, or in case other properties (like age) are specified. This constructor differs from the default in that it requires that a name and breed_list be specified (although it can't ensure that they're strings), and it parses breed_list in a way that the default constructor could not. Is this a legitimate form of instantiation, or should I just use functions or static/class methods? And if it works, why aren't custom constructors used more often?

  • Output of System.out.println(object)

    - by Shaarad Dalvi
    I want to know what exactly the output tells when I do the following : class data { int a=5; } class main { public static void main(String[] args) { data dObj=new data(); System.out.println(dObj); } } I know it gives something related to object as the output in my case is data@1ae73783. I guess the '1ae73783' is a hex number. I also did some work around and printed System.out.println(dObj.hashCode()); I got number 415360643. I got an integer value. I don't know what hashCode() returns, still out of curiosity, when I converted 1ae73783 to decimal, I got 415360643! That's why I am curious that what exactly is this number?? Is this some memory location of Java's sandbox or some other thing? Any light on this matter will be helpful..thanks! :)

  • What is the right method for parsing a blog post?

    - by Zedwal
    Hi guys, Need a guide line .... I am trying to write a personal blog. What is the standard structure for for input for the post. I am trying the format like: This is the simple text And I am [b] bold text[/b].

And What is the right method to parse this kind of post? Shall I use regular expression to parse this or there is another standard for this. If the above mentioned format is not the right way for storage, then what it could be? Thanks

  • Extension method not working if I set controller property in Action, works in OnExecuting

    - by Blankman
    I have a class MyController that inherits from Controller, so all my controllers inherit from MyController. I have a property in MyController: public class MyController : Controller { public string SomeProperty {get;set;} } if I set this property in MyController's OnExecuting method, my HtmlHelper extension method works fine: public static string SomeExtension(this HtmlHelper htmlHelper) { StringBuilder sb = new StringBuilder(); string result = ""; var controller = htmlHelper.ViewContext.Controller as MyController; if (controller != null) { result = controller.SomeProperty; } return result; } it doesn't work if I set 'SomeProperty' in my controllers action method. I guess because I am doing 'as MyController' in the extension method? is there a way for it to work in both situations? I am using the value of SomeProperty to be outputted on my view pages.

  • Custom nib UITableViewCell height

    - by Chuck
    I've created a custom UITableViewCell in IB, linked it to the root view controller's property for it, and set it up in CellForRowAtIndexPath. But the height of my drawn cells doesn't match what I setup in IB, advice? Here's some screenshots and the code. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *AddressCellIdentifier = @"AddressCellIdent"; UITableViewCell *thisCell = [tableView dequeueReusableCellWithIdentifier:AddressCellIdentifier]; if (thisCell == nil) { [[NSBundle mainBundle] loadNibNamed:@"AddressCell" owner:self options:nil]; thisCell = addressCell; self.addressCell = nil; } return thisCell ; } addressCell is a @property (nonatomic, assign) IBOutlet UITableViewCell *addressCell;, and is linked up in IB to the file's owner (the table view controller). I'm using the example from Apple's table view programming guide.

  • Get address using Geocoder in android

    - by user264953
    Hi, I tried to get the address of a particular location by giving static geocordinates. I was not able to fetch the address. Can someone please help. I just need to check whether this function works for me. Here is my snippet. Geocoder geocoder = new Geocoder(AddressSimulator.this, Locale.getDefault()); List<Address> addresses = geocoder.getFromLocation(1.352566007, 103.78921587, 1); System.out.println("Addresses size"+addresses.size()); Address size is obtained as zero. I tried with few other geocordinates also, but address size is always returned as 0. Experts, kindly help me resolve this. Looking forward for your valuable help/suggestions, Best Regards, Rony

  • SVG Using Adobe in IE doesn't work when loading page, but saving the page and then loading it works.

    - by Nick
    So I'm trying to get a SVG document to load in IE. I can see it fine, but all calls to .getSVGDocument() fail, the svg onload="onload()" function never gets called and the right-click Adobe SVG Viewer context menu doesn't show up when right-clicking on the svg. It seems as though I'm managing to crash the adobe SVG viewer or something before it is able to call the onload function but after it has drawn the SVG document. As a test I saved the html page to my hard drive and loaded it up and walla - it works! Right-click, onload, and .getSVGDocument() all work. Very curious. For some reason getting the page from the server makes the adobe plugin crap out but loading up static HTML is fine. Any thoughts?

  • Threading errors with Application.LoadComponent (key already exists)

    - by Kellls
    MSDN says that public static members of System.Windows.Application are thread safe. But when I try to run my app with multiple threads I get the following exception: ArgumentException: An entry with the same key already exists. at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource) at System.Collections.Generic.SortedList`2.Add(TKey key, TValue value) at System.IO.Packaging.Package.AddIfNoPrefixCollisionDetected(ValidatedPartUri partUri, PackagePart part) at System.IO.Packaging.Package.GetPartHelper(Uri partUri) at System.IO.Packaging.Package.GetPart(Uri partUri) at System.Windows.Application.GetResourceOrContentPart(Uri uri) at System.Windows.Application.LoadComponent(Uri resourceLocator, Boolean bSkipJournaledProperties) at System.Windows.Application.LoadComponent(Uri resourceLocator) The application works fine on a single thread and even on two or three. When I get up past 5 then I get the error every time. Am I doing something wrong? What can I do to fix this?

  • passing string literal to std::map::find(..)

    - by ra170
    I've got a std::map. I'm passing string literal to find method. Obviously, I can pass a string literal such as .find("blah"); However, I wanted to declare it upfront, instead of hardcoding the string, so I have couple of choices now: const std::string mystring = "blah"; const char mystring[] = "blah"; static const char * mystring = "blah"; They all work. (or at least compile). My question is, which one should I use? what's the advantage/distavantage over of the other?

  • Problems using jQuery $.ajax to pass data

    - by iboeno
    I'm using ASP.NET and attempting to call a method with a signature of [WebMethod] public static string GetInfo(string id){...} using the following javascript: var elementValue = $("#element").attr('id'); var d = "{id : " + elementValue + "}"; $.ajax({ type: "POST", url: "../WebPage.aspx/GetInfo", data: d, contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { //do this } }); And this is not working. If instead I set elementValue = 2; it works fine. If I try to hardcode in a string value for testing purposes e.g. elementValue = "nameToLookUp"; It fails. Why is this happening, and how do I resolve it? On a side not, why is type: required to be POST instead of a GET? In the end I just want to pass a string value I want to look up in a DB and retrieving some json data.

  • Passenger, Apache and avoiding page caching

    - by Michael Guterl
    I'm hosting a rack application with passenger and apache. The application is setup to cache the content of each request to the public directory after each request. This allows apache to serve the content directly as a static page for future requests. I would like to tell Apache, presumably through some rewrite rules that any requests with query parameters should not be cached, but instead passed down to the rack application. With a mongrel setup I would just redirect it to the balancer if it meets my rewrite conditions. How do you do the same with passenger?

  • How do I marshal a pointer to an array of pointers to structures?

    - by Daniel Stutzbach
    I have a C function with the following signature: int my_function(int n, struct player **players) players is a pointer to an array of pointers to struct player objects. n is the number of pointers in the array. The function does not modify the array nor the contents of the structures, and it does not retain any pointers after returning. I tried the following: [DllImport("mylibary.dll")] static extern int my_function(int n, [In, MarshalAs(UnmanagedType.LPArray, SizeParamIndex = 0)] player_in []players); However, that marshals the data as a pointer to an array of structures, not a pointer to an array of pointers to structures.

  • C++ template parameter/class ambiguity

    - by aaa
    hello. while testing with different version of g++, the following problem came up template<class bra> struct Transform<bra, void> : kernel::Eri::Transform::bra { static const size_t ni = bra::A::size; bra::A is interpreted as kernel::Eri::Transform::bra::A, rather than template argument by g++ 4.1.2. on the other hand, g++ 4.3 gets it right. what should be correct behavior according to standard? Meanwhile, I refactor slightly to make problem go away.

  • library interposition with dlsym

    - by ZeeGeek
    I'm writing an interposition library to track the usage of some library functions in libc, such as open(), close(), connect(), etc. It works generally well on most of the applications. However, when I try it with PHP, using PHP's MySQL module in particular, none of the function calls to libc inside this module is been tracked (so no connect(), no socket(), etc.). 'strace' told me that the system calls socket(), connect(), etc., took place. Running 'file' on the module and libmysqlclient.so.16.0.0 said that they are all dynamically linked. So it shouldn't be a problem caused by static linkage. What might be the problem? I'm using Fedora 11 64-bit version. Thank you.

  • FindBugs and CheckForNull on classes vs. interfaces

    - by ndn
    Is there any way to let FindBugs check and warn me if a CheckForNull annotation is present on the implementation of a method in a class, but not on the declaration of the method in the interface? import javax.annotation.CheckForNull; interface Foo { public String getBar(); } class FooImpl implements Foo { @CheckForNull @Override public String getBar() { return null; } } public class FindBugsDemo { public static void main(String[] args) { Foo foo = new FooImpl(); System.out.println(foo.getBar().length()); } } I just discovered a bug in my application due to a missing null check that was not spotted by FindBugs because CheckForNull was only present on FooImpl, but not on Foo, and I don't want to spot all other locations of this problem manually.

  • Parantheses around method invokation: why is the compiler complaining about assignment?

    - by polygenelubricants
    I know why the following code doesn't compile: public class Main { public static void main(String args[]) { main((null)); // this is fine! (main(null)); // this is NOT! } } What I'm wondering is why my compiler (javac 1.6.0_17, Windows version) is complaining "The left hand side of an assignment must be a variable". I'd expect something like "Don't put parantheses around a method invokation, dummy!", instead. So why is the compiler making a totally unhelpful complaint about something that is blatantly irrelevant? Is this the result of an ambiguity in the grammar? A bug in the compiler? If it's the former, could you design a language such that a compiler would never be so off-base about a syntax error like this?

  • Importing a spreadsheet, but having trouble.

    - by Chris Phelps
    I have a form that allows a user to import a spreadsheet. This spreadsheet is generally static when it comes to column headers, but now the users want to be able to include an optional column (called Notes). My code crashes when I try to read the column from the spreadsheet if it doesn't exist. Dim objCommand As New OleDbCommand() objCommand = ExcelConnection() 'function that opens spreadsheet and returns objCommand Dim reader As OleDbDataReader reader = objCommand.ExecuteReader() While reader.Read() Dim Employee As String = Convert.ToString(reader("User")) Dim SerialNUM As String = Convert.ToString(reader("serialno")) **Dim Notes As String = Convert.ToString(reader("notes"))** If the spreadsheet contains a Notes column, all goes well. If not, crash. How can I check to see if the Notes column exists in the spreadsheet to avoid the crash?
