  • iPhone: image in table cell - wrong position & not scaled correctly in iPhone 3.0

    - by Karsten Silz
    Hi, I have a custom table cell in an iPhone 3.x app to show basketball player data, including a picture. Here's my code from the table controller: UIImageView *theImage = (UIImageView *) [cell viewWithTag:0]; theImage.image = [manager getSmallImageForPlayer: data.number]; theImage.frame = CGRectMake(14, 0, 30, 44); theImage.clipsToBounds = YES; theImage.contentMode = UIViewContentModeScaleAspectFit; theImage.autoresizingMask = UIViewAutoresizingFlexibleHeight && UIViewAutoresizingFlexibleWidth; theImage.autoresizesSubviews = YES; Here's what it looks like in the iPhone SDK 3.0 simulator: Here's what it looks like in the iPhone SDK 3.1.3 simulator: So I have two problems: In both versions, the image view starts at position (0,0) in the table cell, even though I set the frame to start at (14,0). In the 3.0 simulator (and 3.0 device), the image is not shrunk down correctly, even though I set the image view content mode to "UIViewContentModeScaleAspectFit". But the same code works fine in the 3.1.3 simulator / device. Who can help me with either of these two problems?

  • Sharing a session between vBulletin forum and status.net microblogging platform

    - by jaz
    Hello, I need to integrate vBulletin 4.0.3 Publishing Suite with status.net microblogging platform. The first thing I need to do is make these 2 to share 1 session so a user logged in vBulletin forums will also be logged in to status.net and vice versa. I have installed different vBulletin components under different subdomains: forums.sample.com - vBulletin forums blogs.sample.com - vBulletin blogs sample.com - vBulletin content management All of these point to the same place (.../public_html/index.php) which includes the respective php file (content.php for sample.com | blog.php for blogs.sample.com | forum.php for forums.sample.com) depending on the $_SERVER['HTTP_HOST'] I have configured vBulletin to use a single cookie.domain (.sample.com) for all of these 3 domains so visiting different domains doesn't break the session. I also have status.sample.com, which is the subdomain where status.net is installed. The subdomain configuration is different so the document_root is actually a subfolder (.../public_html/status/) in sample.com Now, can you please give me some pointers on how to make all these subdomains share a single session? I'm not sure if it helps, but as I understand, status.net does no custom session handling by default, but it is possible to turn it on so it will start storing session data in a database table called "session". Any tips will be appreciated. Thank you.

  • Date formatting using data annotations for a dataform in Silverlight

    - by Aim Kai
    This is probably got a simple answer to it, but I am having problems just formatting the date for a dataform field.. <df:DataForm x:Name="Form1" ItemsSource="{Binding Mode=OneWay}" AutoGenerateFields="True" AutoEdit="True" AutoCommit="False" CommitButtonContent="Save" CancelButtonContent="Cancel" CommandButtonsVisibility="Commit" LabelPosition="Top" ScrollViewer.VerticalScrollBarVisibility="Disabled" EditEnded="NoteForm_EditEnded"> <df:DataForm.EditTemplate> <DataTemplate> <StackPanel> <df:DataField> <TextBox Text="{Binding Title, Mode=TwoWay}"/> </df:DataField> <df:DataField> <TextBox Text="{Binding Description, Mode=TwoWay}" AcceptsReturn="True" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" Height="" TextWrapping="Wrap" SizeChanged="TextBox_SizeChanged"/> </df:DataField> <df:DataField> <TextBlock Text="{Binding Username}"/> </df:DataField> <df:DataField> <TextBlock Text="{Binding DateCreated}"/> </df:DataField> </StackPanel> </DataTemplate> </df:DataForm.EditTemplate> </df:DataForm> I have bound this to a note class which has the annotation for field DateCreated: /// <summary> /// Gets or sets the date created of the noteannotation /// </summary> [Display(Name="Date Created")] [Editable(false)] [DisplayFormat(DataFormatString = "{0:u}", ApplyFormatInEditMode = true)] public DateTime DateCreated { get; set; } Whatever I set the dataformatstring it comes back as: eg 4/6/2010 10:02:15 AM I want this formatted as yyyy-MM-dd HH:mm:ss I have tried the custom format above {0:yyyy-MM-dd hh:mm:ss} but it remains the same output. The same happens for {0:u} or {0:s}. Any help would be gratefully received. :)

  • 500.19 error in IIS7 when an error occurs

    - by Joel
    Setup: windows 7, IIS7. I am working on an app that is being viewed through the local IIS server, not the built in debugging web server. There is NO <customErrors> section in my web.config. When an error occurs, i see the following message: HTTP Error 500.19 - Internal Server Error Absolute physical path "C:\inetpub\custerr" is not allowed in system.webServer/httpErrors section in web.config file.

  • WPF - Binding an ObservableCollection Dependency Property within a UserControl

    - by John
    I have a control class DragGrid : Grid { ... } which inherits from the original grid and enables dragging and resizing its child elements. I need to bind a custom DP named WorkItemsProperty to an observable collection of type WorkItem (implements INotifyPropertyChanged). Each element in the grid is bound to a collection item. Whenever the user adds a new item dynamically at runtime (the items cannot be declared in XAML!), or deletes an item from that collection, the WorkItems DP on the DragGrid should be updated, and the children in the grid (where each child represents a WorkItem collection item). My question is how does the DP notify the control about which child element in the grid must be removed, changed ('change' means user dragged an element, or resized it with the mouse) or added, and how would I identify which one of the existing children is the one that needs to be deleted or changed. I understand that this is where the DependencyPropertyChangedCallback comes in. But that only gets called when the DP property is set anew, not when something inside the collection changes (like add, remove item). So in the end, does the DragGrid control somehow need to subscribe to the CollectionChanged event? At what point would I hook up the event handler for that?

  • Getting data from UITableView

    - by Tejaswi Yerukalapudi
    Hi, I have a few custom UITableViewCells - http://img11.imageshack.us/i/customfacilitiescell.png/ which are added to this UIViewController - http://img189.imageshack.us/i/facilitycontroller.png/ Now, on clicking a button in the controller, I'd like to get the on/off status of all the UISwitches in the controller. Thanks, Teja Edit: I've made a few edits, but I still can't figure out how to do this. My program structure currently - A CustomCell.xib that looks like this - http://img11.imageshack.us/i/customfacilitiescell.png/ A CustomCellController that a subclass of UITableViewCell that has the IBOutlets for the labels and switches from above. Now I have a UIViewController<UITableViewDataSource, UITableViewDelegate> (Say, Screen1Controller) which looks like - http://img189.imageshack.us/i/facilitycontroller.png/ The tableviewcell is being created like this - - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *Id= @"CustomFacilitiesCell"; CustomFacilitiesCellController *cell = (CustomFacilitiesCellController *)[tableView dequeueReusableCellWithIdentifier:Id]; if(cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomFacilitiesCell" owner:self options:nil]; for (id oneObject in nib) { if([oneObject isKindOfClass:[CustomFacilitiesCellController class]]) cell = (CustomFacilitiesCellController *) oneObject; } } NSUInteger row = [indexPath row]; CustomFacilitiesCellController *rowData = (CustomFacilitiesCellController *)[self.facilities objectAtIndex:row]; cell.facname.text = rowData.facname.text; cell.FacID.text = rowData.FacID.text; cell.facSwitch = [(CustomFacilitiesCellController *)rowData facSwitch]; UISwitch *temp = cell.facSwitch; [(UISwitch *)[cell facSwitch] addTarget:self action:@selector(facSwitchOptionChanged:) forControlEvents:UIControlEventValueChanged]; cell.facSwitch.on = NO; //cell.facSwitch.enabled = FALSE; cell.accessoryType = UITableViewCellAccessoryNone; return cell; } - (IBAction) facSwitchOptionChanged:(id) sender { int i=0; } In particular, my problem is that the facSwitchOptionChanged() isn't getting called. Thanks again for the help, Teja.

  • Unable to debug WCF service in VS2008 after UserNamePasswordValidator fault

    - by lsb
    Hi! I have a WCF service that I secure with a custom UserNamePasswordValidator and Message security running over wsHttpBinding. The release code works great. Unfortunately, when I try to run in debug mode after having previously used invalid credentials (the current credentials ARE valid!) VS2008 displays an annoying dialog box (more on this below). A simplified version of my Validate method from the validator might look like the following: public override void Validate(string userName, string password) { if (password != "ABC123") throw new FaultException("The password is invalid!"); } The client receives a MessageSecurityException with InnerException set to the FaultException I explictly threw. This is workable since my client can display the message text of the original FaultException I wanted the user to see. Unfortunately, in all subsequent service calls VS2008 displays an "Unable to automatically debug..." dialog. The only way I can stop this from happening is to exit VS2008, get back in and connect to my service using correct credentials. I should also add that this occurs even when I create a brand new proxy on each and every call. There's no chance MY channel is faulted when I make a call. Its likely, however, that VS2008 hangs on to the previously faulted channel and tries to use it for debugging purposes. Needless to say, this sucks! The entire reason I'm entering "bad" credentials is to test the "bad-credential" handling. Anyway, if anyone has any ideas as to how I can get around this bug (?!?) I'd be very very appreciative....

  • How to change theme for AlertDialog.

    - by Min Soo Kim
    Hello everyone, I was wondering if someone could help me out. I am trying to create a custom AlertDialog. In order to do this, I added the following line of code in styles.xml @drawable/color_panel_background color_panel_background.9.png is located in drawable folder. This is also available in Android SDK res folder. The following is the main activity. package com.customdialog; import android.app.Activity; import android.app.AlertDialog; import android.app.Dialog; import android.content.DialogInterface; import android.os.Bundle; public class CustomDialog extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); this.setTheme(R.style.CustomAlertDialog); AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setMessage("HELLO!"); builder .setCancelable(false) .setPositiveButton("Yes", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { //MyActivity.this.finish(); } }) .setNegativeButton("No", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { //dialog.cancel(); } }); AlertDialog alertdialog = builder.create(); alertdialog.show(); } } In order to apply the theme to an AlertDialog, I had to set the theme to the current context. However, I just can't seem to get the app to show customized AlertDialog. Can anyone help me out with this, and thank you very much in advance!

  • Strange Behaviour WPF TreeView ItemContainerStyle and ItemTemplate

    - by Matze
    I just noticed some strange behaviour of WPF's TreeView. I added both ItemContainerStyle to bind to "IsSelected" of my ViewModel and an ItemsTemplated for custom display of my data. But now the user cannot change the selected node anymore. For testing purposes I created a similar UI using ListView and Expander. This version works as excepted. Any tips why TreeView does fail? <TreeView ItemsSource="{Binding ElementName=frame, Path=list}"> <TreeView.ItemContainerStyle> <Style TargetType="{x:Type TreeViewItem}" > <Setter Property="IsSelected" Value="{Binding Mode=TwoWay, Path=IsSelected}"/> </Style> </TreeView.ItemContainerStyle> <TreeView.ItemTemplate> <HierarchicalDataTemplate> <TreeViewItem Header="{Binding}"> <TextBlock Text="{Binding Path= Item.SomeData}"/> </TreeViewItem> </HierarchicalDataTemplate> </TreeView.ItemTemplate> </TreeView>

  • How can I sort a DataGridTemplateColumn on a WPF Toolkit DataGrid?

    - by Kilhoffer
    I have a WPF Toolkit DataGrid with one DataGridTemplateColumn. I've specified in a grid attribute that I wish all columns to be sortable, but the DataGridTemplateColumn won't allow it. All other columns do allow sorting. I've even tried explicitly setting CanUserSort to true for that column, but no luck. Is it even possible to sort a template column? I've provided a custom sorter that works for all columns, but the header won't allow a sort click. <Controls:DataGrid ItemsSource="{Binding Events}" AutoGenerateColumns="False" CanUserSortColumns="True" CanUserReorderColumns="False" Sorting="DataGrid_Sorting" x:Name="EventsGrid"> <Controls:DataGrid.Columns> <Controls:DataGridTemplateColumn Header="Type" Width="42" CanUserResize="False"> <Controls:DataGridTemplateColumn.CellTemplate> <DataTemplate> <Image Source="{Binding EventTypeImage, Mode=OneWay}" HorizontalAlignment="Center" Width="16"/> </DataTemplate> </Controls:DataGridTemplateColumn.CellTemplate> </Controls:DataGridTemplateColumn> <Controls:DataGridTextColumn Header="Source" Binding="{Binding Source, Mode=OneWay}" /> <Controls:DataGridTextColumn Header="Details" MinWidth="175" Binding="{Binding Details, Mode=OneWay}" /> <Controls:DataGridTextColumn Header="Timestamp" MinWidth="175" Binding="{Binding Timestamp, Mode=OneWay}" IsReadOnly="True"/> </Controls:DataGrid.Columns> </Controls:DataGrid>

  • UIScrollView frame size issue in Landscape Mode

    - by viper15
    I'm trying to make UIScrollView auto-resize and appear correctly in Landscape mode. Portrait mode works fine. Here's my code: - (void)viewDidLoad { [super viewDidLoad]; //=== load all the custom view NSMutableArray *controllers = [[NSMutableArray alloc] init]; int page = 0; [controllers addObject:[self loadScrollView:[[Page1ViewController alloc] initWithNibName:@"Page1ViewController" bundle:nil] withPage:page++]]; [controllers addObject:[self loadScrollView:[[Page2ViewController alloc] initWithNibName:@"Page2ViewController" bundle:nil] withPage:page++]]; [controllers addObject:[self loadScrollView:[[Page3ViewController alloc] initWithNibName:@"Page3ViewController" bundle:nil] withPage:page++]]; self.viewControllers = controllers; [controllers release]; //=== automaticaly define number of pages _numberOfPages = [self.viewControllers count]; // a page is the width of the scroll view scrollView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; scrollView.pagingEnabled = YES; scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * _numberOfPages, scrollView.frame.size.height); scrollView.showsHorizontalScrollIndicator = NO; scrollView.showsVerticalScrollIndicator = NO; scrollView.scrollsToTop = NO; scrollView.delegate = self; // First, set the number of pages pageControl.numberOfPages = _numberOfPages; pageControl.currentPage = 0; } Then, I went into each view controller nib file and set the background to different color to test if it's working. Unfortunately, when in Landscape mode, the width and height remains the same as in Portrait Mode. I'm not sure how to fix this problem. Hope anyone can help me. Many thanks in advance.

  • jQuery UI dialog on ASP.NET page (inside user control)

    - by marc_s
    I have a really odd behavior here: I created a little popup dialog in jQuery UI, and in my test HTML page, it works flawlessly. When I click on the button, the popup comes up, covers the background, and remains on screen until I click on one of the two buttons (OK or Cancel) provided. So now I wanted to add this into my ASP.NET 3.5 app. I wanted to add it to a GridView inside a user controls (ASCX), which is on a page (ASPX) contained inside a master page. The jQuery 1.4.2 and jQuery UI 1.8.1 scripts are referenced on the master page: <body> <form id="XXXXXX" runat="server"> <Ajax:ScriptManager ID="masterScriptManager" runat="server" ScriptMode="Auto"> <Scripts> <asp:ScriptReference Path="~/Scripts/jquery-1.4.2.min.js" /> <asp:ScriptReference Path="~/Scripts/jquery-ui-1.8.1.custom.min.js" /> </Scripts> </Ajax:ScriptManager> I had to change this to use the Ajax script manager, since adding them to the as never worked. So in my gridview, I have a column with image buttons, and when the user clicks on those, I am calling a little javascript function to show the jQuery UI dialog: function showDialog() { $("#dlg-discount").dialog('open'); $("#txtAmount").focus(); } When I run this page in MS IE 8, I get a separate page, and at the top of the page, I get the contents of my , with proper background color and all. In Firefox 3.5.6, I do get the dialog as a popup. In both cases, the dialog page/popup disappears again after a second or less - without me clicking anything! It seems similar to this question but the solution provided there doesn't work in my case. This one here also seems similar but again: the solution presented doesn't seem to work in my case... Any ideas / hints / tips on what the h** is going on here?? Thanks!

  • How to create a MVC 2 DisplayTemplate for a field whose display format is dependent on another field

    - by Glenn
    If I have a property whose display format is dependent on the value of another property in the view model how do I create a display template for it? The combination of field1's display being dependent on field2's value will be used throughout the app and I would like to encapsulate this in a MVC 2 display template. To be more specific, I've already create a display template (Social.ascx) for custom data type Social that masks a social security number for display. For instance, XXX-XX-1234. [DataType("Social")] public string SocialSecurityNumber { get; set; } All employees also have an employeeID. Certain companies use the employee's social security number as either the whole employee id or as part of it. I need to also mask the employeeID if it contains the social. I'd like to create another display template (EmpID.ascx) to perform this task. [DataType("EmpID")] public string EmployeeID { get; set; } The problem is that I don't know how to get both properties in the "EmpID" template to be able to perform the comparison. Thanks for the help.

  • Using QTDesigner with PyQT and Python 2.6

    - by PyNewbie27
    Hi. I'm fairly new to Python and trying to work with the latest versions of QTDesigner, PyQT 4.7 and QT4.7 (I downloaded the whole package from PyQT4.7 website). I can't figure out how to make QTDesigner integrate closely with Python: ie. If I select "Form" View Code in QTDesigners menu, it errors saying "Unable to launch C:/Python26/Lib/site-packages/PyQT4/bin\uic." If I look in that directory there is a pyuic.py but not "uic". From searching online it seems this doesn't exist because it's expecting a C++ install instead of the python version. Is there anyway to make QTDesigner use/call pyuic.py to generate the code, then open an IDE or text editor of my choice to show me the PYTHON code generated by the QTDesigner-PyUIC chain? I'd like Designer to integrate closely with python, so I can make custom slots/signals in Designer while designing, then tweak the python code directly in my IDE later. If it is not possible to code directly inside QTDesigner using python, does that mean I have to hand code my programs entire UI directly in my PythonIDE? Using Designer directly would seemingly be nearly very very nice for a newbie such as myself, since I can see what properties each widget has and visually edit them while still learning the QT syntax without constantly having to use web resources to see what properties each widget should have and helps with boilerplate code generation, and what their defaults are, etc. I've googled and nobody seems to be using QTDesigner and Python in this manner together. It seems most are either handcoding all the QT code in their Python IDE of choice, or have found an obvious/easy method of doing what I want, therefore not really producing up to date tutorials on making this work together. Please enlighten me if you can. Thanks in advance for your time. Please include any suggestions you might have to a newbie trying to use Python with QT and QTDesigner. Thank you.

  • ExtJS GridPanel Scrollbar does not appear in IE7 but it does in Firefox, etc

    - by Snowright
    Setup I have an accordion layout containing a "properties" panel that nests two inner panels. The first inner panel holds a Ext.DataView, while the second panel is the Ext.grid.GridPanel in question. In the screenshot below, the white space containing the folder icon is the dataview, and below that is the gridpanel. Problem In Firefox, Chrome, and Opera, there is a scrollbar that appears when my gridpanel has an overflow of properties. It is only in Internet Explorer that it does not appear. I am, however, able to scroll using my mouse scroll button in all browsers, including IE. I've also tried removing our custom css file in case it was affecting it somehow, but there was no change in doing so. I'm not sure exactly what code I should show as I don't know where the exact problem is coming from but here is the code for the mainpanel and gridpanel. var mainPanel = new Ext.Panel({ id : 'main-property-panel', title : 'Properties', height : 350, autoWidth : true, tbar : [comboPropertyActions], items : [panel1] //panel1 holds the DataView }); var propertiesGrid = new Ext.grid.GridPanel({ stripeRows : true, height : mainPanel.getSize().height-iconDataView.getSize().height-mainPanel.getFrameHeight(), autoWidth : true, store : propertiesStore, cm : propertiesColumnModel }) //Add gridpanel to mainPanel mainPanel.add(propertiesGrid); mainPanel.doLayout(); Any help into the right direction would be greatly appreciated. Thank you.

  • jQuery autocomplete - update options on dynamically created elements

    - by Ian Robinson
    Background The user enters values into multiple inputs on the page. Think of entering a list of widgets for sale. The user would select the type of a widget from a drop down. Then enter the name of the Widget vendor, and then the actual name of the widget. These UI elements would all appear as one row. The user is able to click an "add another widget" link and a new row is created. The two input elements have autocomplete functionality attached to them using the DevBridge jQuery plugin. It suggests the name of the vendor and the name of the widget. I have recently wired up the logic to filter the name of the widget based on the name of the vendor you entered. This means setting the (custom) vendorName parameter when attaching the autocomplete plugin so it can be passed to the server side to retrieve the widget names for that vendor that match the name the user entered. To achieve this functionality I'm dynamically attaching the autocomplete functionality to the second element (the widget name text box) when it receives focus. Here is an example: $('.autocomplete-widget').live('focus', function () { $(this).autocomplete({ serviceUrl: '/something.ashx', params: { type: 'widget', vendorName: $(this).parent().prev().find('.autocomplete-vendor').val()} }); }); Problem At first glance, this looks to function quite well. However I started noticing some inconsistencies, and upon inspection, I found out that the call to the server is actually happening several times in some cases. Each time the widget name input element receives focus the autocomplete functionality is attached. And what I'm seeing is that the call to the server is made in proportion to how many times the input element has gained focus. I'd like to avoid making the call more than once, but retain the ability to attach (or update) the autocomplete functionality "on focus". I've tried to use the autocomplete 'setOptions' method but have only been able to get it to work with the static elements, not the dynamically created elements. Question Is there a way I can clear out the autocomplete functionality before I attach another one?

  • ASP.Net MVC2 (RTM) breaks response filtering - "Filtering is not allowed"

    - by womp
    I've just done a test run of upgrading a project to ASP.Net MVC 2 (RTM) in anticipation of the full official .Net 4.0 release coming later this month. Our application is using a minimizer for our CSS and javascript. To do so, it is making use of the HttpResponse.Filter property to set a custom filter. With the upgrade, the setter for this property is throwing an HttpException saying "Filtering is not allowed." Looking that the HttpResponse.Filter property in reflector shows this: set { if (!this.UsingHttpWriter) { throw new HttpException(SR.GetString("Filtering_not_allowed")); } ... private bool UsingHttpWriter { get { return ((this._httpWriter != null) && (this._writer == this._httpWriter)); } } Clearly something has changed in the way the HttpResponse is writing to the output stream in MVC2. Does anyone know what the change is, or at least a workaround for this? EDIT: This seems pretty radical. Some further investigation shows that ASP.Net MVC 2 RTM is using a System.Web.Mvc.ViewPage.SwitchWriter as the Output property of an HttpResponse, whereas MVC 1 was using a plain old HttpWriter. That explains why the exception is being thrown. But that doesn't explain why they've chosen to completely break this functionality. This thread seems to indicate that this is just temporary... but this makes me pretty nervous... this is the RTM after all. Any further comments appreciated on this.

  • jqGrid Coloring an entire line in Grid based upon a cells value

    - by Thomas
    Hi all, i know it's been asked before but i cant get it to run and i'm out of things to try. So i want to colorize a row in a Grid if its value is not 1 - i use a custom formatter for this. The formatter itself works, thats not the problem. I've tried multple ways I've found so far on the web - adding a class, directly adding css code, using setRowData, using setCell.... Here are my examples - none of them worked for me (linux, ff363) - any pointer would be gratly appreciated. 27.05.2010_00:00:00-27.05.2010_00:00:00 is my row id <style> .state_inactive { background-color: red !important; } .state_active { background-color: green !important; } </style> function format_state (cellvalue, options, rowObject) { var elem='#'+options.gid; if (cellvalue != 1) { jQuery('#list2').setRowData(options.rowID,'', {'background-color':'#FF6F6F'}); jQuery('#list2').setRowData('27.05.2010_00:00:00-27.05.2010_00:00:00', '',{'background-color':'#FF6F6F'}); for (var cnt=0;cnt<rowObject.length;cnt=cnt+1) { jQuery(elem).setCell(options.rowId,cnt,'','state_inactive',''); jQuery(elem).setCell('"'+options.rowId+'"',cnt,'','state_inactive'); jQuery(elem).setCell('"'+options.rowId+'"',cnt,'5', {'background-color':'#FF6F6F'},''); } } else { for (var cnt=0;cnt<rowObject.length;cnt=cnt+1) { jQuery(elem).setCell(options.rowId,cnt,'','state_active',''); } } <!-- dont modify, we simply added the class above--> return cellvalue; } Thanks, Thomas

Instead of passing datatables around, I am thinking about using custom objects so that I am loosely coupled to my data layer and can take advantage of intellisense in VS. I assume these objects would be considered DTOs? First, where do these objects reside in my layers? BLL, DAL, other? Second, when populating from SQL, should I loop through a data reader to populate the list or first fill a data table, then loop through the table to populate the list? I know you should close the database connection as soon as possible, but it seems like even more overhead to populate the data table and then loop through that for the list. Third, everything I see these days says use Linq2SQL. I am planning to learn Linq2SQL, but at this time I am working with a legacy database that doesn't have foreign keys setup and I do not have the ability to fix it atm. Also, I want to learn more about c# before I start getting into ORM solutions like nHibernate. At the same time I don't want to type out all the connection and SQL plumbing for every query. Is it ok to use the Enterprise DAAB for now?

  • Using RabbitMQ (Java client), is there a way to determine if network connection is closed during con

    - by MItch Branting
    I'm using RabbitMQ on RHEL 5.3 using the Java client. I have 2 nodes (machines). Node1 is consuming messages from a queue on Node2 using the Java helper class QueueingConsumer. QueueingConsumer consumer = new QueueingConsumer(channel); channel.basicConsume("MyQueueOnNode2", noAck, consumer); while (true) { QueueingConsumer.Delivery delivery = consumer.nextDelivery(); ... Process message - delivery.getBody() } If the interface is brought down on Node1 or Node2 (e.g. ifconfig eth1 down), the client (above) never knows the network isn't there anymore. Does RabbitMQ provide some type of configuration on the Java client that can be used to determine if the connection has gone away. Shutting down the RabbitMQ server on Node2 will trigger a ShutdownSignalException, which can be caught and the app can go into a reconnect loop. But bringing down the interface doesn't cause any type of exception to happen, so the code will be waiting forever on consumer.nextDelivery(). I've also tried using the timeout version of this call. e.g. QueueingConsumer consumer = new QueueingConsumer(channel); channel.basicConsume("MyQueueOnNode2", noAck, consumer); int timeout_ms = 30000; while (true) { QueueingConsumer.Delivery delivery = consumer.nextDelivery(timeout_ms); if (delivery == null) { if (channel.isOpen() == false) // Seems to always return true { throw new ShutdownSignalException(); } } else { ... Process message - delivery.getBody() } } but appears that this always returns true (even though the interface is down). I assume registering for the ShutdownListener on the connection will yield the same results, but haven't tried that yet. Is there a way to configure some sort of heartbeat, or do you just have to write custom lease logic (e.g. "I'm here now") in order to get this to work?

  • Python Image Library, Close method

    - by DNN
    Hello, I have been using pil for the first time today. And I wanted to resize an image assuming it was larger than 800x600 and also create a thumbnail. I could do either of these tasks separately but not together in one method (I am doing a custom save method in django admin). This returns a "cannot identify image file" error message. The error is on the line "image = Image.open(self.photo)" after "#if image is size is greatet than 800 x 600 then resize image." I thought this may be because the image is already open, but if i remove the line I still get issues. So I thought I could try closing after creating a thumbnail and then reopening. But I couldn't find a close method.... This is my code: def save(self): #create thumbnail Thumb_Size = (75, 75) image = Image.open(self.photo) if image.mode not in ('L', 'RGB'): image = image.convert('RGB') image.thumbnail(Thumb_Size, Image.ANTIALIAS) temp_handle = StringIO() image.save(temp_handle, 'jpeg') temp_handle.seek(0) suf = SimpleUploadedFile(os.path.split(self.photo.name)[-1], temp_handle.read(), content_type='image/jpg') self.thumbnail.save(suf.name+'.jpg', suf, save=False) #if image is size is greatet than 800 x 600 then resize image. image = Image.open(self.photo) if image.size[0] > 800: if image.size[1] > 600: Max_Size = (800, 600) if image.mode not in ('L', 'RGB'): image = image.convert('RGB') image.thumbnail(Max_Size, Image.ANTIALIAS) temp_handle = StringIO() image.save(temp_handle, 'jpeg') temp_handle.seek(0) suf = SimpleUploadedFile(os.path.split(self.photo.name)[-1], temp_handle.read(), content_type='image/jpg') self.photo.save(suf.name+'.jpg', suf, save=False) #enter info to database super(Photo, self).save()

  • How do I make an ellipse blink?

    - by MedicineMan
    I am trying to make a custom control in WPF. I want it to simulate the behavior of a LED that can blink. There are three states to the control: On, Off, and Blinking. I know how to set On and Off through the code behind, but this WPF animation stuff is just driving me nuts!!!! I cannot get anything to animate whatsoever. The plan is to have a property called state. When the user sets the value to blinking, I want the control to alternate between green and grey. I'm assuming I need a dependency property here, but have no idea. I had more xaml before but just erased it all. it doesn't seem to do anything. I'd love to do this in the most best practice way possible, but at this point, I'll take anything. I'm half way to writing a thread that changes the color manually at this point. <UserControl x:Class="WpfAnimation.LED" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300"> <Grid> <Ellipse x:Name="MyLight" Height="Auto" Width="Auto"/> </Grid> </UserControl>

  • MVCContrib ActionFilter PassParametersDuringRedirect still passes reference type in querystring

    - by redsquare
    I am attempting to use the PRG pattern in an asp.net mvc 2 rc application. I found that the MVCContrib project has a custom action filter that will auto persist the parameters in TempData In an action I have the following return this.RedirectToAction(c => c.Requested(accountAnalysis)); however this is adding a querystring param to the request e.g http://mysite.com/account/add?model=MyProject.Models.AccountAnalysisViewModel Can anyone explain how I can use the PassParametersDuringRedirect filter attribute from MVCContrib to not pass the ViewModel type in the querystring. I see a patch was issued to fix this however in the latest MvcContrib that supports MVC 2 RC it is commented out as follows public static RedirectToRouteResult RedirectToAction<T>(this Controller controller, Expression<Action<T>> action) where T : Controller { /*var body = action.Body as MethodCallExpression; AddParameterValuesFromExpressionToTempData(controller, body); var routeValues = Microsoft.Web.Mvc.Internal.ExpressionHelper.GetRouteValuesFromExpression(action); RemoveReferenceTypesFromRouteValues(routeValues); return new RedirectToRouteResult(routeValues);*/ return new RedirectToRouteResult<T>(action); } Any help much appreciated. Thanks

  • Android - Using PreferenceScreen to display and save settings to/from ContentProvider

    - by Donal Rafferty
    I have my own custom Content Provider that loads a datasbase which contains the settings information for my application. I load the settings from the ContentProvider on the creation of my Settings activity. My Settings activity is made up of a PreferenceScreen and Dialog based EditText's. The following code shows how I use the preference screen and edit texts. So as you can see from the first image this works and displays the menu with the information underneath. The problem is in image two, when I click on a choice in the menu the dialog pops up but it is empty, I would like to be able to load the data from my content provider into the edit text in the dialog, so in image one it shows "Donal" as the user name so in image two "Donal" should also appear in the edit text in the dialog. I would also like to be able to listen to the OK button in the dialog so when a user changes a setting I can update the data in my content provider. Can anyone help me with what I'm trying to do? Code // Root PreferenceScreen root = getPreferenceManager().createPreferenceScreen(this); // Dialog based preferences PreferenceCategory dialogBasedPrefCat = new PreferenceCategory(this); dialogBasedPrefCat.setTitle(R.string.dialog_based_preferences); root.addPreference(dialogBasedPrefCat); // Edit text preference EditTextPreference editTextPref = new EditTextPreference(this); editTextPref.setDialogTitle(R.string.dialog_title_edittext_preference); editTextPref.setKey("edittext_preference"); editTextPref.setTitle(R.string.title_edittext_preference); editTextPref.setSummary(name); dialogBasedPrefCat.addPreference(editTextPref); Image One Image Two
