  • Can't access dojo object property using string variable

    - by Kareem
    I am retrieving a json associative array using a dojo xhrGet request. The data comes back just fine, however I need the app to be able to display the keys and their properties (or values) without knowing the keys beforehand. So, I do the following: function getData() { dojo.xhrGet( { url: "ytd_process.php", handleAs: "json", load: function(response) { for (var key in response) { dojo.byId("boxes").innerHTML+="<div id=\"box\">"+key+":"+response.key+"</div>"; } console.dir(response); // Dump it to the console } }); }; The keys are retrieved and displayed on the page, but the response.key returns undefined. I know the syntax is correct because if I replace .key with an actual key value it will display correctly. It appears it doesn't like a string as the key. Any help or advice would be greatly appreciated. Thank you.

  • Having difficulty add a custom icon to a JFrame

    - by Oliver
    Hi, I have been trying to change the icon in the frame. I have virtually tried everything: The icon is 16x16 which is the right size ....doesn't work I've trying PNG,GIF and JPG formats none of them work. Tried different way of setting the icon....doesn't work. I've tried relative (local paths) e.g. "icon.gif" and absolute paths e.g. "c:\work\java\icon.gif" ...doesn't work Here is my code and see if you can figure it out Thanks Oli import javax.swing.*; public class androidDriver { public static void main(String[] args) throws IOException { JFrame f = new JFrame("Android Data Viewer"); f.setResizable(false); f.setSize(300,300); f.setLocationRelativeTo(null); f.setVisible(true); f.setIconImage(new ImageIcon("androidIcon2.gif").getImage()); } }

  • Call function under object from string

    - by sam
    I have a script which creates a drag-and-drop uploader on the page from a div. My DIV will look something like <div class="well uploader" data-type="image" data-callback="product.addimage" data-multi="1"></div> Then I'll have a function something like var product = new function(){ /* Some random stuff */ this.addimage = function(image){ alert('W00T! I HAZ AN IMAGE!'); } /* More random stuff */ } When the upload is complete, I need to call the function in data-callback (In this example, product.addimage). I know with global functions you can just do window[callback]() but I'm not sure the best way to do this with functions under objects. My first thought was to do something like* var obj = window; var parts = callback.split('.'); for(part in parts){ obj = obj[parts[part]]; } obj(); but that seems a bit dirty, is there a better way without using eval because eval is evil? I haven't tested this so I have no idea if it will work

  • Placing & deleting element(s) from a object (stack)

    - by Chris
    Hello, Initialising 2 stack objects: Stack s1 = new Stack(), s2 = new Stack(); s1 = 0 0 0 0 0 0 0 0 0 0 (array of 10 elements wich is empty to start with) top:0 const int Rows = 10; int[] Table = new int[Rows]; public void TableStack(int[] Table) { for (int i=0; i < Table.Length; i++) { } } My question is how exactly do i place a element on a stack (push) or take a element from the stack (pop) as the following: Push: s1.Push(5); // s1 = 5 0 0 0 0 0 0 0 0 0 (top:1) s1.Push(9); // s1 = 5 9 0 0 0 0 0 0 0 0 (top:2) Pop: int number = s1.Pop(); // s1 = 5 0 0 0 0 0 0 0 0 0 0 (top:1) 9 got removed Do i have to use get & set, and if so how exactly do i implent this with a array? Not really sure what to exactly use for this. Any hints highly appreciated. The program uses the following driver to test the Stack class (wich cannot be changed or modified): public void ExecuteProgram() { Console.Title = "StackDemo"; Stack s1 = new Stack(), s2 = new Stack(); ShowStack(s1, "s1"); ShowStack(s2, "s2"); Console.WriteLine(); int getal = TryPop(s1); ShowStack(s1, "s1"); TryPush(s2, 17); ShowStack(s2, "s2"); TryPush(s2, -8); ShowStack(s2, "s2"); TryPush(s2, 59); ShowStack(s2, "s2"); Console.WriteLine(); for (int i = 1; i <= 3; i++) { TryPush(s1, 2 * i); ShowStack(s1, "s1"); } Console.WriteLine(); for (int i = 1; i <= 3; i++) { TryPush(s2, i * i); ShowStack(s2, "s2"); } Console.WriteLine(); for (int i = 1; i <= 6; i++) { getal = TryPop(s2); //use number ShowStack(s2, "s2"); } }/*ExecuteProgram*/ Regards.

  • Custom keys with NERDComment plugin and remapped Leader?

    - by Paul Wicks
    I'm trying to set up the NERDComment plugin in vim, but I'm having some trouble with the keys. I'd like to set the basic toggle functionality (comment a line if it's uncommented, uncomment if it's commented) to be c. The problem is that I've remapped the Leader to be ,, which is the same key that NERD wants for all of it's hotkeys. Anyone have any idea as to how to set this up?

  • Access custom label property at didSelectRowAtIndexPath.

    - by Mr. McPepperNuts
    I have a UILabel for each cell at cellForRowAtIndexPath. UILabel *cellLabel = [[UILabel alloc] initWithFrame:frame]; cellLabel.text = myString; I want to access that string "myString" at didSelectRowAtIndexPath using indexpath. NSString *anotherString = cell.textLabel.text; returns null. Now if at cellForRowAtIndexPath, I did something like cell.textLabel.text = theString; then the didSelectRowAtIndexPath returns the appropriate cell. My question is, how can I access the text in the UILabel I apply to the cell, at didSelectRowAtIndexPath? Also, logging the cell in didSelectRowAtIndexPath returns cell: <UITableViewCell: 0x5dcb9d0; frame = (0 44; 320 44); autoresize = W; layer = <CALayer: 0x5dbe670>> Edit: NSString *myString = [[results objectAtIndex:indexPath.row] valueForKey:@"name"]; //cell.textLabel.text = myString; CGFloat width = [UIScreen mainScreen].bounds.size.width - 50; CGFloat height = 20; CGRect frame = CGRectMake(10.0f, 10.0f, width, height); UILabel *cellLabel = [[UILabel alloc] initWithFrame:frame]; cellLabel.text = myString; cellLabel.textColor = [UIColor blackColor]; cellLabel.backgroundColor = [UIColor whiteColor]; cellLabel.textAlignment = UITextAlignmentLeft; cellLabel.font = [UIFont systemFontOfSize:14.0f]; [cell.contentView addSubview:cellLabel]; [cellLabel release]; return cell;

  • using the data-custom="" to bind to events

    - by Dean Peterson
    I'm pretty sure I'm gonna get slammed on this. I love using the data-whatever attribute to bind events to. It feels very clean to me and helps reserve my class attribute for just styling. I know this selector is among the slowest, so I don't use it when there are a lot of elements. Would love to hear compelling arguments against this. $("body").delegate("[data-action]", "click", function(){ var action = $(this).attr("data-action"); //route action to appropriate function });

  • Implementing "Generator" support in a custom language

    - by Roger Alsing
    I've got a bit of fettish for language design and I'm currently playing around with my own hobby language. (http://rogeralsing.com/2010/04/14/playing-with-plastic/) One thing that really makes my mind bleed is "generators" and the "yield" keyword. I know C# uses AST transformation to transform enumerator methods into statemachines. But how does it work in other languages? Is there any way to get generator support in a language w/o AST transformation? e.g. Does languages like Python or Ruby resort to AST transformations to solve this to? (The question is how generators are implemented under the hood in different languages, not how to write a generator in one of them)

  • Processing file uploads before object is saved

    - by Dominic Rodger
    I've got a model like this: class Talk(BaseModel): title = models.CharField(max_length=200) mp3 = models.FileField(upload_to = u'talks/', max_length=200) seconds = models.IntegerField(blank = True, null = True) I want to validate before saving that the uploaded file is an MP3, like this: def is_mp3(path_to_file): from mutagen.mp3 import MP3 audio = MP3(path_to_file) return not audio.info.sketchy Once I'm sure I've got an MP3, I want to save the length of the talk in the seconds attribute, like this: audio = MP3(path_to_file) self.seconds = audio.info.length The problem is, before saving, the uploaded file doesn't have a path (see this ticket, closed as wontfix), so I can't process the MP3. I'd like to raise a nice validation error so that ModelForms can display a helpful error ("You idiot, you didn't upload an MP3" or something). Any idea how I can go about accessing the file before it's saved? p.s. If anyone knows a better way of validating files are MP3s I'm all ears - I also want to be able to mess around with ID3 data (set the artist, album, title and probably album art, so I need it to be processable by mutagen).

    Hi, In the aspx code view, we can code like this: <asp:ListBox runat="server"> <asp:ListItem Text="Item1" /> <asp:ListItem Text="Item2" /> </asp:ListBox> However, the ListItem class is not a server control. How could we do that? Is there some attributes being consumed by the visual studio? Thanks:)

  • DriverManager always returns my custom driver regardless of the connection URL

    - by JGB146
    I am writing a driver to act as a wrapper around two separate MySQL connections (to distributed databases). Basically, the goal is to enable interaction with my driver for all applications instead of requiring the application to sort out which database holds the desired data. Most of the code for this is in place, but I'm having a problem in that when I attempt to create connections via the MySQL Driver, the DriverManager is returning an instance of my driver instead of the MySQL Driver. I'd appreciate any tips on what could be causing this and what could be done to fix it! Below is a few relevant snippets of code. I can provide more, but there's a lot, so I'd need to know what else you want to see. First, from MyDriver.java: public MyDriver() throws SQLException { DriverManager.registerDriver(this); } public Connection connect(String url, Properties info) throws SQLException { try { return new MyConnection(info); } catch (Exception e) { return null; } } public boolean acceptsURL(String url) throws SQLException { if (url.contains("jdbc:jgb://")) { return true; } return false; } It is my understanding that this acceptsURL function will dictate whether or not the DriverManager deems my driver a suitable fit for a given URL. Hence it should only be passing connections from my driver if the URL contains "jdbc:jgb://" right? Here's code from MyConnection.java: Connection c1 = null; Connection c2 = null; /** *Constructors */ public DDBSConnection (Properties info) throws SQLException, Exception { info.list(System.out); //included for testing Class.forName("com.mysql.jdbc.Driver").newInstance(); String url1 = "jdbc:mysql://server1.com/jgb"; String url2 = "jdbc:mysql://server2.com/jgb"; this.c1 = DriverManager.getConnection( url1, info.getProperty("username"), info.getProperty("password")); this.c2 = DriverManager.getConnection( url2, info.getProperty("username"), info.getProperty("password")); } And this tells me two things. First, the info.list() call confirms that the correct user and password are being sent. Second, because we enter an infinite loop, we see that the DriverManager is providing new instances of my connection as matches for the mysql URLs instead of the desired mysql driver/connection. FWIW, I have separately tested implementations that go straight to the mysql driver using this exact syntax (al beit only one at a time), and was able to successfully interact with each database individually from a test application outside of my driver.

  • Object C casting

    - by ct2k7
    Hi, I'm trying to cast this statement: [self handError:noConnectionError]; basically, this statement is in a class, which is not the app delegate, but is the .m file of a view, specifically a view after uitableview, which contains its own uiviewtable. The warning that statement gives me is that the error produced may not be apparent to the UIView (view control container).

  • How to display custom processing message in JQuery datatables

    - by Sukhi
    i am using datatables api to display data in my asp.net4.0 application; datatables I have one column [ Delete ] to delete the row data.when i click on this link i send a jquery ajax request to delete the row from database. I want to display a message such as [ Deleting record... ] to the end user until data deleted by server side processing. I put a div on my page and write a message [ Deleting record... ] in a div when i click on delete link i display that message but when delete operation complete it also display a message [ Processing... ](which is inbuilt message of datatables) which looks like odd as two message are displaying. What can i do better to display message to the end user. JSCode $('#tblVideoList .delete').live('click', function (e) { e.preventDefault(); var oTable = $('#tblVideoList').dataTable(); var aPos = oTable.fnGetPosition(this.parentNode); var aData = oTable.fnGetData(aPos[0]); if (confirm('Are you sure want to delete the record.')) { $("#divDelete").show(); var today = new Date(); $.ajax({ type: "GET", cache: false, url: "samplepage.aspx", success: function (msg) { $("#divDelete").hide(); oTable.fnDraw(); } }); } return false; }); Thanks

  • Browser Helper Object doesnot get loaded in IE8

    - by velusbits
    I have a BHO, which i can see it as enabled in Add On's list. But it does not get loaded when i start my IE on the Win2k8 R2 machines(64 bit). I have disabled IE Enhanced security as well but no help. The same BHO gets loaded in other machines. The registry details under (HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects & HKEY_CLASSES_ROOT\Wow6432Node\CLSID) seem to be fine. Is there any setting that disables BHO from actually getting loaded?

  • Problem displaying Vertex Buffer Object (OpenGL and Obj-C)

    - by seaworthy
    Hey, I am having a problem displaying or loading a buffer with an array of vertices. I know that array works fine because I am able to render it using a loop and a glVertex command. I can't figure out what's wrong. Your insight is highly appreciated. GLuint vboId; glGenBuffers( 1, &vboId ); glBindBuffer( GL_ARRAY_BUFFER, vboId); glBufferData( GL_ARRAY_BUFFER, count*sizeof( GLfloat ),array,GL_STATIC_DRAW_ARB ); glBindBuffer( GL_ARRAY_BUFFER, 0 ); printf("%d\n",count); glEnableClientState( GL_VERTEX_ARRAY ); glBindBuffer( GL_ARRAY_BUFFER, vboId ); glVertexPointer( 3, GL_FLOAT, 0, 0 ); glDisableClientState( GL_VERTEX_ARRAY ); printf("vboId: [%hd]",vboId); glDeleteBuffers(1, &vboId); Help?
