  • How can I shift html-text in the JButton to the left?

    - by Roman
    I use HTML to put text into a JButton. In this way I can play with colors and text size. What I do not like is the distance from the left border of the button and the text (this separation is too large). Is there a way to decrease this distance? I think it should be some parameter in the style of the HTML code. Sample of the code: JButton btn = new JButton("<html><span style='color:#000000; font-size: 11pt;'>" + label + "</span></html>");

  • Lock HTML select element, allow value to be sent on submit

    - by ILMV
    I have a select box (for a customer field) on a complex order form, when the user starts to add lines to the order they should not be allowed to change the customer select box (unless all lines are deleted). My immediate thought was that I could use the disabled attribute, but when the box is disabled the selected value is no longer passed to the target. When the problem arose a while ago one of the other developers worked around this by looping through all the options and disabling all but the selected option, and sure enough the value was passed to the target and we've been using since. But now I'm looking for a proper solution, I don't want to loop through all the options because are data is expanding and it's starting to introduce performance issues. I'd prefer not to enable this / all the elements when the submit button is hit. How can I lock the input, whilst maintaining the selected option and passing that value to the target script? I would prefer a non-JavaScript solution if possible, but if needed we are running jQuery 1.4.2 so that could be used.

  • Service Application too visible

    - by Tom
    Working on a service application in Delphi 5 that is intended to run on Windows XP - 7. Most of the application is coming together nicely, but I'm running into one issue. Part of this service application is a form that displays data occasionally (similar to the slider box Avast uses to let you know its updated). When the service shows the form, the form displays on the taskbar, but we don't want it to. Does anyone have any suggestions as to how to hide the form's button on the taksbar? None of the standard methods I've found for regular applications have worked so far. Thanks.

  • NavBar displaying back twice when app changed to landscape mode

    - by Graeme
    Hi, Not sure what's going on here, but my iPhone apps nav bar shows back and the title of my detail view controller even when I'm back to the original view. It wasn't happening earlier, it has changed recently (but not sure when exactly). E.g. I click on a row, view the didSelectRow XIB and then click back on the NavBar controller, but it still shows back even though the view does change back to the original table view. I then have to press back again and then it clears. Update: It's as if its trying to go back three times instead of two. Because, if you visit another row without removing the back button, it stores it as if you need to go back twice. It works fine in portrait mode. Any ideas?

  • Radio buttons: Replacing the stock round ones with built in android buttons

    - by Aaron Kapitsk
    Hi all, how do I create a group of radio buttons where the buttons look like nice stock android buttons? This is what I have found so far: * The look of radio button can be replaced with 4 drawables. * There is an example of ^^ on the web. This does not work for me. So I have figured out two bad choices: A) Use stock buttons -do the radio logic in java. //Gross B) Render the buttons to drawables set them at runtime //Blah Any ideas are very appreciated. (This is my first question here. Hope it is well formulated.)

  • Is it possible to convert Gregorian to Hijri date in Vb ?

    - by ahmed
    Hi, I have a table in sql where the date format is stored in Hijri. Now I am working on a vb.net application where I have to let the user update that dateField. So is it possible that if I place a datepicker(which is in Gregorian) and user selects the date and its converts into Hijri date before updating. I mean when the user selects the date and clicks the save button the date should be updated in hijri format in the sql . For now , the user is entering the date manually on a tms AdvEdit. Is there any code available to accomplish this task. Thanking you all in advance for your time and consideration.

  • How to programmatically set a data cell of database in VB.Net?

    - by manuel
    I have a Microsoft Access database file connected to VB.NET. In the database table, I have a 'No.' and a 'Status' column. Then I have a textbox where I can input an integer. I also have a button, which will change the data cell in 'Status' where 'No.' = textbox.Text(), when I click it. Let's say I want the 'Status' cell to be changed to "Low". What codes should I put in the button_Click event handler? Here is the codes I used to retrieve and display the database table. Public Class theForm Dim con As New OleDb.OleDbConnection Dim ds As New DataSet Dim daTitles As OleDb.OleDbDataAdapter Private Sub theForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load con.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=|DataDirectory|\db1.mdb" con.Open() daTitles = New OleDb.OleDbDataAdapter("SELECT * FROM Titles", con) daTitles.Fill(ds, "Titles") DataGridView1.DataSource = ds.Tables("Titles") DataGridView1.AutoResizeColumns() End Sub

  • JavaScript on Android randomly stops working

    - by AndersWid
    Hi! I have an application that uses a WebView and a html-page with javascript functions. Randomly the JavaScript functions doesn't seem to be called. It works up to a random point (I have looked at this bug all day) can only be produced on hardware (HTC Legend) not on emulator. Basicly I'm using callback to javaScript whenever the user presses a button, these callbacks tell the html to redraw using javaScript functions. mHandler.post(new Runnable() { public void run() { mWebView.loadUrl("javascript:getDataLine()"); } }); The first line in this javaScript code is an alert that says that it has started, so that I can see that it's working. Settings alerts or console.log's everywhere won't help as it seems the problem is in the webview or in Android itself. I need a way to see what's going on in the background. Maybe see if a previous call failed and stalled the thread or something.

  • TabBar implementation issue in iphone

    - by iPhoneDev
    Hi, My project is navigation based template and it was running fine until I made changes in some child view. I need to add 4 Tab in some child view. So what I did is create a TabBarController programmatically on ViewDidLoad as: // (void)viewDidLoad { [super viewDidLoad]; helpView = [[HelpView alloc] initWithNibName:@"HelpView" bundle:nil]; settingView = [[SettingView alloc] initWithNibName:@"SettingView" bundle:nil]; tabBarController = [[UITabBarController alloc] init]; tabBarController.viewControllers = [NSArray arrayWithObjects:helpView,settingView,nil]; [self.view addSubview:[tabBarController view]]; } I am able to add two view in tab bar but not Tab Title. Please let me know what I am missing to display Title on tab button. ( Is a NavigationBased project) Thanks

  • [Simple] Beginner AJAX script not working, stuck on opening XMLHttpRequest

    - by Julian H. Lam
    Hopefully, this question isn't too juvenile to ask - but here goes: I'm trying to learn AJAX, and I'm stuck on a simple content-fetch. Here is my code: request = getHTTPObject(); function useHttpResponse() { if (request.readyState == 4) { document.getElementById("p").innerHTML = request.responseText; } } function update_p() { request.open("GET",content.html,true); request.onreadystatechange = useHttpResponse; } getHTTPObject is correctly defined, and returns a proper XMLHttpObject. As you probably guessed from the excerpt, the element I am trying to update is id'd "p". It calls the script correctly when a button is clicked, no problem there. The script seems to stop at line 8, at request.open. There's no error, and the script silently ignores anything afterward. I don't think I've missed anything, but of course, I probably did. Where did I go wrong? Thanks!

  • [grails] attaching multiple files to a domain class

    - by Emyr
    I've seen various Grails plugins which allow easier handling of file uploads, however these tend only to support a single file per form-submit. I'd like a multi-attach form where as soon as you pick one file, an extra field and button is added using JS (various sites do it like this). Do you know of any good plugins which provide elegant uploading of multiple files without excessive coding? A progress bar either per-file of for the whole process would also be very nice. I don't know to what extent I can allow GORM to handle a java.io.File field (or in this case a Collection<File>).

  • How to extract delegates from ViewController class?

    - by adranle
    Hi I have the problem that my view controller class has too many delegates and starts to get big. I want to write the delegates in separate classes to keep the view controller class small. For delegates that are programmatically created (like UIAlertViewDelegate) I could do it easily. The problem is in the delegates assigned in Interface Builder. How can I tell the IB to assign, for example, another class as the UITableViewDelegate or UITableViewDataSource? Or how to choose another IBAction method for a Touch UP inside Event on a button? One solution would be to delete the connections from IB and write them programmatically at ViewDidLoad, but since I have a lot of ViewControllers, this would take a long time. any other ideas?

  • How to show a client-side message with Java JSF/Tobago?

    - by Marcus
    I have a web application created with JSF and Tobago. The user types some date into a sheet and clicks a button (all within one sheet-row). Now my java class checks whether the data is correct or not. In case there are some problems, I would like to show up something like a messagebox containing the errormessage. I cannot use something like JDialog, since this would happen only server side. Every user independently of his location needs to get the message. I thought about setting the error information into a databean and having my jsp show up the message after reloading. But how can I achieve this? Is there something like a tag which can be used for this? Or can I use the "confirmation" facet for this? But how would I start it without having the user to do something? Thanks in advance!

  • Enable editing does not call didSelectRowAtIndexPath ??

    - by elementsense
    Hi I have a UITableViewController where the user should be able to edit the items. In order to enable editing i use this : self.navigationItem.rightBarButtonItem = self.editButtonItem; And for everyone, how does not know where self.editButtonItem comes from, it is predefined by the SDK. So, now when I press on any item, this method is called : - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath but as soon as I hit the edit button and while editing is active, this method does not seemed to be called. Any idea what I missing ? This is the rest of the code that is related to editing : // Override to support conditional editing of the table view. - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath { // Return NO if you do not want the specified item to be editable. return YES; } - (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath { return UITableViewCellEditingStyleNone; } - (BOOL)tableView:(UITableView *)tableView shouldIndentWhileEditingRowAtIndexPath:(NSIndexPath *)indexPath { return NO; } Thanks for the help. mcb

  • Losing NSManaged Objects in my Application

    - by Wayfarer
    I've been doing quite a bit of work on a fun little iPhone app. At one point, I get a bunch of player objects from my Persistant store, and then display them on the screen. I also have the options of adding new player objects (their just custom UIButtons) and removing selected players. However, I believe I'm running into some memory management issues, in that somehow the app is not saving which "players" are being displayed. Example: I have 4 players shown, I select them all and then delete them all. They all disappear. But if I exit and then reopen the application, they all are there again. As though they had never left. So somewhere in my code, they are not "really" getting removed. MagicApp201AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; context = [appDelegate managedObjectContext]; NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *desc = [NSEntityDescription entityForName:@"Player" inManagedObjectContext:context]; [request setEntity:desc]; NSError *error; NSMutableArray *objects = [[[context executeFetchRequest:request error:&error] mutableCopy] autorelease]; if (objects == nil) { NSLog(@"Shit man, there was an error taking out the single player object when the view did load. ", error); } int j = 0; while (j < [objects count]) { if ([[[objects objectAtIndex:j] valueForKey:@"currentMultiPlayer"] boolValue] == NO) { [objects removeObjectAtIndex:j]; j--; } else { j++; } } [self setPlayers:objects]; //This is a must, it NEEDS to work Objects are all the players playing So in this snippit (in the viewdidLoad method), I grab the players out of the persistant store, and then remove the objects I don't want (those whose boolValue is NO), and the rest are kept. This works, I'm pretty sure. I think the issue is where I remove the players. Here is that code: NSLog(@"Remove players"); /** For each selected player: Unselect them (remove them from SelectedPlayers) Remove the button from the view Remove the button object from the array Remove the player from Players */ NSLog(@"Debugging Removal: %d", [selectedPlayers count]); for (int i=0; i < [selectedPlayers count]; i++) { NSManagedObject *rPlayer = [selectedPlayers objectAtIndex:i]; [rPlayer setValue:[NSNumber numberWithBool:NO] forKey:@"currentMultiPlayer"]; int index = [players indexOfObjectIdenticalTo:rPlayer]; //this is the index we need for (int j = (index + 1); j < [players count]; j++) { UIButton *tempButton = [playerButtons objectAtIndex:j]; tempButton.tag--; } NSError *error; if ([context hasChanges] && ![context save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } UIButton *aButton = [playerButtons objectAtIndex:index]; [players removeObjectAtIndex:index]; [aButton removeFromSuperview]; [playerButtons removeObjectAtIndex:index]; } [selectedPlayers removeAllObjects]; NSError *error; if ([context hasChanges] && ![context save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } NSLog(@"About to refresh YES"); [self refreshAllPlayers:YES]; The big part in the second code snippet is I set them to NO for currentMultiPlayer. NO NO NO NO NO, they should NOT come back when the view does load, NEVER ever ever. Not until I say so. No other relevant part of the code sets that to YES. Which makes me think... perhaps they aren't being saved. Perhaps that doesn't save, perhaps those objects aren't being managed anymore, and so they don't get saved in. Is there a lifetime (metaphorically) of NSManaged object? The Players array is the same I set in the "viewDidLoad" method, and SelectedPlayers holds players that are selected, references to NSManagedObjects. Does it have something to do with Removing them from the array? I'm so confused, some insight would be greatly appreciated!!

  • Graceful DOS Command Error-Handling w/PHP popen()

    - by Captain Obvious
    PHP 5.2.13 on Windows 2003 I am using the DOS Start /B command to launch a background application using the PHP popen() function: popen("start /B {$_SERVER['HOMEPATH']}/{$app}.exe > {$_SERVER['HOMEPATH']}/bg_output.log 2>&1 & echo $!", 'r'); The popen() function launches a cmd.exe process that runs the specified command; however, if the command fails (e.g. the {$app}.exe doesn't exist or is locked in the above example), the cmd.exe process never returns, and PHP hangs indefinitely as a result. Calling the failing DOS command directly using the Command Prompt results in an Error prompt that requires clicking the OK button. I assume this error confirmation requirement is what's preventing the cmd.exe process from returning to PHP both from the Command Prompt (using both CGI and CLI) and the web (using Apache 2.0 handler w/Apache 2.2). Is there a way to configure PHP, Apache, and/or Win 2003 to return the DOS error to the originating call rather than waiting for confirmation?

  • Making span clickable after prepend in jQuery

    - by Saif Bechan
    I have a DIV where some code is presented. When I hover on this DIV I want to present a button that toggles the comments inside the code block. So far I have this: $('.code-block').hover( function(){ $(this).prepend('<span class="code-block-control">toggle comments</span>'); }, function(){ $('.code-block-control',this).remove(); } ); $('.code-block-control').click( function(){ $('.comment').toggle(); } ); The span is presented when I hover over the code block. But when I click the span that is created nothing happens. Even if I change the click function to a simple alert nothing happens. Anyone have any idea on how to fix this.

  • C# GridView dynamically built columns with textboxes ontextchanged

    - by tnriverfish
    My page is a bulk order form that has many products and various size options. I've got a gridview that has a 3 static columns with labels. There are then some dynamically built columns. Each of the dynamically built columns have a textbox in them. The textbox is for quantity. Trying to either update the server with the quantity entered each time a textbox is changed (possibly ontextchanged event) or loop though each of the rows column by column and gather all the items that have a quantity and process those items and their quantities all at once (via button onclick). If I put the process that builds the GridView behind a if(!Page.IsPostBack) then the when a textchanged event fires the gridview only gets the static fields and the dynamic ones are gone. If I remove the if(!Page.IsPostBack) the process to gather and build the page is too heavy on processing and takes too long to render the page again. Some advice would be appreciated. Thanks

    I'm not really familiar with PHP exporting to excel or csv, but I'm using PHP MySQL for a local point of sale. According to the code below, this actually works..But not in the way it should be ! All records are placed as 1 row inside the csv file, how can i fix that ? Also, How would I stop overwriting the same file...I mean When I click on a Button to export the csv, it should check if there is an existing csv file, If there is--Create new one ! Thank You require_once('connect_db.php'); $items_array = array(); $result = mysql_query("SELECT * FROM sold_items"); while($row = mysql_fetch_array($result)) { $items_array[] = $row['item_no']; $items_array[] = $row['qty']; } $f = fopen('C:/mycsv.csv', 'w'); fputcsv($f, $items_array); fclose($f);
