• UIView fine for iPhone 4in, but squashed in iPhone 3.5in

  - by coopersita

  I started a new project in the new Xcode, and I see that my default the main window is set to 320x548. I'm fine with that, but when I test my app, a view I added to my main xib, which is supposed to be 280x280, looks more like 280x200 when testing on 3.5in devices. I've tried changing the settings for that view in the xib, but nothing seems to affect it. How do I ensure background compatibility so that in older devices the view is the same size?

• jQuery AJAX functions

  - by sundowatch

  I am using jQuery's load() function when getting a page to a div like that: content.php page is : <script type="text/javascript"> $(".content").load("asd.php"); </script> and asd.php is: <script type="text/javascript"> alert("Hello World"); </script> When load ajax finished alert() message appears 3 times. Actually it must appears only 1 time. So load() function get page 3 times. How can I get the page a time?

• Python 3.1: Syntax Error for Everything! (Mac OS X)

  - by Nathan G.

  I updated to Python 3.1.3 (I've got OS X 10.6). If I type python in Terminal, I get a working 2.6.1 environment. If I type python3 in Terminal, I get a 3.1.3 environment. Everything looks fine until I do something. If I try to run print "hello", I get a syntax error. This problem is the same in IDLE. I tried deleting everything for 3.1 and then reinstalling, but it hasn't worked. Ideas? Thanks in advance!

• Algorithm of JavaScript "sort()" Function

  - by Knowledge Craving

  Recently when I was working with JavaScript "sort()" function, I found in one of the tutorials that this function does not sort the numbers properly. Instead to sort numbers, a function must be added that compares numbers, like the following code:- <script type="text/javascript"> function sortNumber(a,b) { return a - b; } var n = ["10", "5", "40", "25", "100", "1"]; document.write(n.sort(sortNumber)); </script> The output then comes as:- 1,5,10,25,40,100 Now what I didn't understand is that why is this occurring & can anybody please tell in details as to what type of algorithm is being used in this "sort()" function? This is because for any other language, I didn't find this problem where the function didn't sort the numbers correctly. Any help is greatly appreciated.

• allignment issue of div tag

  - by Quasar the space thing

  I am trying to create a web page where on click of a button I can add div tags. What I thought to do was that I'll create two div tags within a single div so that over all presentation will be uniform and similar to a table having two columns and multiple rows and the first column contains only label's and second column will contain textbox. Here is the JS file : var counter = 0; function create_div(type){ var dynDiv = document.createElement("div"); dynDiv.id = "divid_"+counter; dynDiv.class="main"; document.body.appendChild(dynDiv); question(); if(type == 'ADDTEXTBOX'){ ADDTEXTBOX(); } counter=counter+1; } function question(){ var question_div = document.createElement("div"); question_div.class="question"; question_div.id = "question_div_"+counter; var Question = prompt("Enter The Question here:", ""); var node=document.createTextNode(Question); question_div.appendChild(node); var element=document.getElementById("divid_"+counter); element.appendChild(question_div); } function ADDTEXTBOX(){ var answer_div = document.createElement("div"); answer_div.class="answer"; answer_div.id = "answer_div_"+counter; var answer_tag = document.createElement("input"); answer_tag.id = "answer_tag_"+counter; answer_tag.setAttribute("type", "text"); answer_tag.setAttribute("name", "textbox"); answer_div.appendChild(answer_tag); var element=document.getElementById("divid_"+counter); element.appendChild(answer_div); } Here is the css file : .question { width: 40%; height: auto; float: left; display: inline-block; text-align: justify; word-wrap:break-word; } .answer { padding-left:10%; width: 40%; height: auto; float: left; overflow: auto; word-wrap:break-word; } .main { width: auto; background-color:gray; height: auto; overflow: auto; word-wrap:break-word; } My problem is that the code is working properly but both the divisions are not coming in a straight line. after the first div prints on the screen the second divisions comes in another line. How can I make both the div's come in the same line ? Thank You. PS : should I stick with the current idea of using div or should I try some other approach ? like tables ?

• Get info about Http Post field order

  - by Eugene

  Is it possible to get information about post field order in ASP.NET? I need to know whether some field was the last one or not. I know I can do it through Request.InputStream, but I’m looking for a more high level solution without manually stream parsing. Generally I’m doing testing of http post sent by my application and there is no practical usage for this in ASP.NET.

• assembly.GetTypes() does not return all types

  - by meta

  I try to lead the types from an .dll (which is also referenced in the executing project). I call: public static void LoadPlugin(string pluginFile) { Assembly assembly = Assembly.LoadFrom(pluginFile); foreach (Type type in assembly.GetTypes()) { // play with it } } It loads just a few of them: public partial class Mathematics : UserControl, IMathematics, IPortable and public partial class Welcome : UserControl but the next one, and some others, are ignored: public partial class Test : UserControl, ITest, IPortable They all stand in the same assembly, under the same namespace. The public static void LoadPlugin(string pluginFile) method is located in other assembly that is also referenced in the executing project. No exceptions are thrown. What could be the issues for not loading all the types? Any ideas?

• Stringly typed values table in sql, is there a better way to do this? (we're using MSSQL)

  - by Jason Hernandez

  We have have a table layout with property names in one table, and values in a second table, and items in a third. (Yes, we're re-implementing tables in SQL.) We join all three to get a value of a property for a specific item. Unfortunately the values can have multiple data types double, varchar, bit, etc. Currently the consensus is to stringly type all the values and store the type name in the column next to the value. tblValues DataTypeName nvarchar Is there a better, cleaner way to do this?

• Take a string to a byte[]

  - by Vaccano

  I have a string in my database that represents an image. It looks like this: 0x89504E470D0A1A0A0000000D49484452000000F00000014008020000000D8A66040.... <truncated for brevity> When I load it in from the database it comes in as a byte[]. How can I convert the string value to a byte array myself. (I am trying to remove the db for some testing code.)

• How to check null element if it is integer array in Java?

  - by masato-san

  I'm quite new to Java and having an issue checking null element in integer array. I'm using Eclipse for editor and the line that checks null element is showing error: Line that complains: if(a[i] != null) { Error msg from Eclipse: The operator != is undefined for the argument type(s) int, null In PHP, this works without any problem but in Java it seems like I have to change the array type from integer to Object to make the line not complain (like below) Object[] a = new Object[3]; So my question is if I still want to declare as integer array and still want to check null, what is the syntax for it? Code: public void test() { int[] a = new int[3]; for(int i=0; i<a.length; i++) { if(a[i] != null) { //this line complains... System.out.println('null!'); } } }

• Outlook 2007 plugin

  - by JL

  I am about to embark on my first outlook 2007 plugin. I would like to create a new tool bar that will have a button that will initially be disabled. When the user selects a message the button should be enabled... but only if the email is of a certain type of email... This is where I need your expert advice, is there a way to quickly flag an email in outlook, so that in the email select event you can look for a property of that email... for example... on_select if mail.type = "FromISP" then I would prefer not to use the from field.... the other thing is during the send process I need to set the flag, I am doing this again using .net so I have full control over how the mail is created. Any ideas would help... Thanks

• Function Composition in Haskell

  - by Watts

  I have a function that takes 3 functions and switches the types and combine to make a new function. For example a test case call would be : (chain init tail reverse ) "Haskell!" the output should be lleksa I've tried to do this problem a few different ways including using the map function but I kept getting association problems. so i did chain :: Ord a => [a] -> a chain f g h x = f.g.h$x my error is Couldn't match expected type[t0->t1->t2->a0] When I type the problem directly into prelude like replacing f, g, h, x with the values it comes out right Is there even a way to do three functions, I've only seen two in examples

• C# Why does calling an interface member from a class generate an error?

  - by Jack

  So I have an interface: interface IFoo { int Bar(); int this[int i] {get; set;} } And a class that derives from it class Foo : IFoo { public int IFoo.Bar() { //Implementation { public int IFoo.this[int i] { //Implementation } } Now, I try to do this: var fooey = new Foo(); int i = Fooey.Bar(); or this: int i = Fooey[4]; I would expect these to work properly. However, the compiler generates an error as if such members don't exist. Why is that? I am aware I can cast Foo as IFoo, but I am also aware that casting is costly to performance, which is often the reason to use interfaces in the first place. EDIT 1: These are the errors generated 'Foo' does not contain a definition for 'Bar' and no extension method 'Bar' accepting a first argument of type 'Foo' could be found (are you missing a using directive or an assembly reference?) "Cannot apply indexing to an expression of type 'Foo'"

• Should I share UI for objects that use common fields?

  - by wb

  I have a parent class that holds all of the fields that are common between all device types. From that, I have a few derived classes that each hold their unique fields. Say I have device type "Switch" and "Transformer". Both derived classes only have 2-3 of their own unique fields. When doing the UI design (windows forms) in this case. Should I create two separate forms for each device type or create a user control with all fields that are shared among all devices? Thank you.

• Elegant way to search for UTF-8 files with BOM?

  - by vog

  For debugging purposes, I need to recursively search a directory for all files which start with a UTF-8 byte order mark (BOM). My current solution is a simple shell script: find -type f | while read file do if [ "`head -c 3 -- "$file"`" == $'\xef\xbb\xbf' ] then echo "found BOM in: $file" fi done Or, if you prefer short, unreadable one-liners: find -type f|while read file;do [ "`head -c3 -- "$file"`" == $'\xef\xbb\xbf' ] && echo "found BOM in: $file";done It doesn't work with filenames that contain a line break, but such files are not to be expected anyway. Is there any shorter or more elegant solution? Are there any interesting text editors or macros for text editors?

• What is wrong with the below statement(C#3.0 / Lambda)

  - by Newbie

  what is wrong in the below Enumerable.Range(0, objEntityCode.Count - 1).Select(i => { options.Attributes[i] = new EntityCodeKey { EntityCode = objEntityCode[i].EntityCodes , OrganizationCode = Constants.ORGANIZATION_CODE }; }) .ToArray(); Throwing error The type arguments for method 'System.Linq.Enumerable.Select(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly. But this works Enumerable.Range(0, objEntityCode.Count - 1).ToList().ForEach(i => { options.Attributes[i] = new EntityCodeKey { EntityCode = objEntityCode[i].EntityCodes , OrganizationCode = Constants.ORGANIZATION_CODE }; } ); Using C#3.0. Purpose: I am learning LINQ / LAMBDA and trying to do the same program in different way. Thanks.
