  • Why does this textbox binding example work in WPF but not in Silverlight?

    - by Edward Tanguay
    Why is it in the following silverlight application that when I: change the default text in the first textbox move the cursor to the second text box (i.e. take focus off first textbox) click the button that inside the button handler, it still has the old value "default text"? What do I have to do to get the binding to work in Silverlight? The same code works fine in WPF.

  • Navbar Menu Trouble shoot

    - by Nabeel M
    So I wanted to create the fixed nav bar on top of the page. Instead of creating nav bar with ordered list, I used the following approach: <header> <div class="nav"> <img src="images/logo_ab.png" alt="AurinBioTech Logo"/> <a href="index.html">Home</a> <a href="#">About</a> <a href="#">Team</a> <a href="#">Science</a> <a href="#">Need</a> <a href="#">Pipeline</a> <a href="#">Contact</a> </div> </header> CSS: header .nav { margin-top:100px; width:100%; height:10%; text-align:center; padding-top:2%; margin:0 auto; position:fixed; top:0; } header .nav a { font-size: 2em; padding-left: 15px; padding-right: 15px; color:rgb(1, 1, 1); text-decoration: none; font-family: 'Bebas'; } header .nav a:hover { color:white; background-color: #404040; border-radius:5px; padding:0 auto; } header .nav a:active{ background-color: #404040; border-radius:5px; text-decoration:overline; } header .nav img { width:260px; height:65px; padding-right:4em; } The reason I used this approach is because I wanted to use logo image next to the nav bar so it would align properly in the same line. Now the problem is that I need to add sub-menus under Science and Pipeline heading. Since I didn't use UL or LI, how can I add sub-menus under those heading. OR, can you tell me any other way to create a NAV bar that shows the logo as well. so it would be LOGO and MENUS on the same line. Great thanks in advance.

  • Two loops speeds drawing in a Jframe

    - by noahn567
    I have a program that requires two classes. The player-Names class, and the Player-Model class. I want the player-Names class to repaint every half second, and the Player-Model class to repaint 60 times per second because i want the movement to be smooth. The problem that i am having is that i want all of this to be done on one J-frame. How would i go about doing this? If you could lead me in the right direction or give me a little example that would be great! Thank you :). for some reason it wont let me post so i'm going to put in some random code import java.awt.Color; import java.awt.Font; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.RenderingHints; import javax.swing.JComponent; import javax.swing.JFrame; public class PlayerNames extends JFrame { static int connectionTimer = 0; static int connectionTimer2 = 0; static int reconnect = 0; static int reconnectValue = 1; static int x = 0; static int reconnectWait = connectionTimer + reconnectValue; private static final long serialVersionUID = 1L; public graph gg = new graph(); public graph g = new graph(); private static GameClient socketClient; private GameServer socketServer; public static void main(int width, int height) { PlayerNames tt = new PlayerNames(); // PlayerGraphics t = new PlayerGraphics(); tt.setSize(width, height); if (Game.ServerOwner == 1) { tt.setTitle("Server: " + Game.username); } else { tt.setTitle("Username: " + Game.username); } tt.setVisible(true); tt.getContentPane().add(tt.gg); tt.getContentPane().add(tt.g); tt.setDefaultCloseOperation(EXIT_ON_CLOSE); tt.setResizable(false); }

  • How to get unique values when using a UNION mysql query

    - by Roland
    I have 2 sql queries that return results, both contain a contract number, now I want to get the unique values of contract numbers HEre's the query (SELECT contractno, dsignoff FROM campaigns WHERE clientid = 20010490 AND contractno != '' GROUP BY contractno,dsignoff) UNION (SELECT id AS contractno,signoffdate AS dsignoff FROM contract_details WHERE clientid = 20010490) So for example, if the first query before the union returns two results with contract no 10, and the sql query after the union also returns 10, then we have 3 rows in total, however because contractno of all three rows is 10, I need to have only one row returned, Is this possible?

  • cellForRowAtIndexPath not being called, but rowsInSections is and it's delegate is set

    - by Jhorra
    I searched around prior to posting this and made sure I hadn't missed anything obvious, though I have a feeling I am missing something basic. I'm using this as a sidebar navigation view. I tried making them static cells and pre-populating them, but they were blank that way as well. When I do it this way I can see everything gets called except that. I've tried deleting it and re-adding it. #import "acxSideBarController.h" @interface acxSideBarController () @end @implementation acxSideBarController @synthesize sidebarDelegate = _sidebarDelegate; - (id)initWithStyle:(UITableViewStyle)style { self = [super initWithStyle:style]; if (self) { // Custom initialization } return self; } - (void)viewDidLoad { [super viewDidLoad]; if ([self.sidebarDelegate respondsToSelector:@selector(lastSelectedIndexPathForSidebarViewController:)]) { NSIndexPath *indexPath = 0; [self.tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone]; } self.tableView.backgroundColor = [UIColor underPageBackgroundColor]; self.tableView.dataSource = self; self.tableView.delegate = self; } - (void)viewDidUnload { [super viewDidUnload]; } - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationPortrait); } #pragma mark - Table view data source - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 3; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if(section == 0) return 2; else if(section == 1) return 1; else return 1; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"linkCell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } NSString *name = @""; if(indexPath.section == 1) name = @"Inbox"; else if(indexPath.section == 2) name = @"Logout"; else { if(indexPath.row == 0) name = @"Roster"; else if(indexPath.row == 1) name = @"Environmental Variables"; } cell.textLabel.text = name; cell.textLabel.textColor = [UIColor darkTextColor]; return cell; } - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { if(section == 0) return @"Students"; else if(section == 1) return @"Communication"; else return @" "; } #pragma mark - Table view delegate - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (self.sidebarDelegate) { [self.sidebarDelegate acxSideBarController:self atIndexPath:indexPath]; } } @end If it's helpful here's the header file #import <UIKit/UIKit.h> @protocol acxSideBarControllerDelegate; @interface acxSideBarController : UITableViewController @property (nonatomic, assign) id <acxSideBarControllerDelegate> sidebarDelegate; @end @protocol acxSideBarControllerDelegate <NSObject> - (void)acxSideBarController:(acxSideBarController *)acxSideBarController atIndexPath:(NSIndexPath *)indexPath; @optional - (NSIndexPath *)lastSelectedIndexPathForacxSideBarController:(acxSideBarController *)acxSideBarController; @end

  • div "top" bug IE and everything else. Big problem

    - by Victor
    Hi everyone. I am new in CSS so please help me in this problem. I hope to describe it wright. I am making div named content where my site content is. I made it with z-index:-1; so an image to be over this div. But in Chrome, FF and safari, content became inactive. I cant select text , click on link and write in the forms. So I tried with positive states in the z-index but IE don't know what this means. Damn. So I decided to make conditional div. Here is the code: .content { background:#FFF; width:990px; position:relative; float:left; top:50px; } .content_IE { background:#FFF; width:990px; position:relative; float:left; top: 50px; z-index:-1; } and here is the HTML: <!--[if IE 7]> <div class="content_IE" style="height:750px;"> <![endif]--> <div class="content" style="height:550px;"> Everything is fine with the z-index but the problem is that if there is no top in .content class everything looks fine in IE but there is no space in the other browsers. If i put back the top:50px; there onother 50px like padding in the .content_IE class. I mean that the page looks like I've put top:50px; and padding-top=50px;. I've try everything like margin-top:-50px; padding-top:-50px; and stuff like this but I am still in the circle. It look fine only if there is no top option in .content class. Please help.
