    - by H4mm3rHead
    He, I have this page where i have checkboxes next to every item in a table, and want to allow the user to select some of them and press my delete button. I just cant come up with the jquery for making the confirm window and submitting only if 'yes' is pushed - this is my page <%Html.BeginForm(); %> <%List<ShopLandCore.Model.SLGroup> groups = (List<ShopLandCore.Model.SLGroup>)Model; %> <%Html.RenderPartial("AdminWorkHeader"); %> <table width="100%" id="ListTable" cellpadding="0" cellspacing="0"> <tr> <td colspan="5" class="heading"> <input type="submit" name="closeall" value="Close selected" /> <input type="submit" name="deleteall" value="Delete selected" /> </td> </tr> <tr> <th width="20px"> </th> <th> Name </th> <th> Description </th> <th width="150px"> Created </th> <th width="150px"> Closed </th> </tr> <%foreach (ShopLandCore.Model.SLGroup g in groups) { %> <tr> <td> <%=Html.CheckBox(g.Id.ToString()) %> </td> <td> <%=g.Name %> </td> <td> <%=g.Description %> </td> <td> <%=g.Created %> </td> <td> <%=g.Closed %> </td> </tr> <%} %> </table> <%Html.EndForm(); %> Please note that its only for the delete that it should confirm, and not necessarily for the close button.

  • How to show Iplmage format on the GUI of C++ instead of showing it in another windows?

    - by Darren
    I'm trying to display the output image onto the C++ interface instead of creating another window to display the image. For example: cvNameWindow("Window A",0); cvShowImage("Window A", imgA); This will create an window and display the imgA on it. My question is that can i display my imgA onto my C++ interface together with all my other button and textbox. I'm using Borland C++ Builder 6 and OpenCV.

  • Local and global variables in javascript

    - by caramel1991
    Today,I started to code a page that prompt the user to choose their PC spec,and the code is as follow <html> <title>Computer Specification Chooser</title> <head> <script type="text/javascript"> var compSpec = document.compChooser; function processorUnavailable_onclick() { alert("Sorry that processor speed is currently unavailable"); compSpec.processor[2].checked = true; } </script> </head> <body> <form name="compChooser"> <p>Tick all components you wan included on your computer</p> <p> DVD-ROM <input type="checkbox" name="chkDVD" value="DVD-ROM" /> <br /> CD-ROM <input type="checkbox" name="chkCD" value="CD-ROM" /> <br /> Zip Drive <input type="checkbox" name="chkZIP" value="ZIP DRIVE" /> </p> <p> Select the processor speed you require <br /> <input type="radio" name="processor" value="3.8" /> 3.8 GHZ <input type="radio" name="processor" value="4.8" onclick="processorUnavailable_onclick()" /> 4.8 GHZ <input type="radio" name="processor" value="6" /> 6 GHZ </p> <input type="button" name="btnCheck" value="Check Form" /> </form> </body> </html> The problem I'm facing is on the function that I've tie to the event handler,when I try to choose the radio button of the processor value 4.8 GHZ,yes it alert me with the message inside the function,but after that,it doest not execute the next statement inside the function,that is to check the next processor value 6 GHZ. I've try my effort to change it and test on it,and find out when I set the var compSpec = document.compChooser as a local variable inside the function instead of a global variable,the next statement could be executed. But I thought for a global variable,it is accessible in everywhere on the page and also inside a function.But why now I can't accesses it inside my function??Any idea?? Besides,I stumble upon a weird article while googling,it says that when a global variable is created,it is added to window object.I just curious why this happen??And what's the benefits and uses of it?? THANK YOU

  • Javascript: move the "view point" of the browser

    - by ArchJ
    I have a page with many out-of-bounds contents and since I set body{overflow:hidden}, they are not outside the viewport. So I want to attach a function to a button which would move the PoV of the browser so that the out-of-bounds contents would come into the viewport. What I can think of now is to set body{position:relative} and use jQuery to animate() the body instead. But in terms of performance, is there a better way to achieve that?

  • WPF application in a one window

    - by lukas
    I would like to make an application in a one window using XAML. It should be like a slideshow with next and back button. One idea is to make 4 panels and have just one enable at the time. Is there any other way to do this? Like dynamic loading of other XAML? is it the BackgroundWorker mandatory to use with WPF (hence is DirectX rendered there's almost no GUI lags) ?

  • Should I use ICommand or Expression.Interactions InvokeCommand for MVVM in Silverlight 4?

    - by phejndorf
    I'm about to embark on a new project in Silverlight 4, and definitely want to take advantage of the MVVM pattern, now I've finally grasped the basics. For implementing commands in Silverlight 4 it seems there are rather a lot of options ranging from the new built-in Command/ICommand option on the Button, over the InvokeCommand defined in the Microsoft.Expressions.Interactivity namespace and on to the range of assisting MVVM frameworks (Prism, MVVMlight etc). Does anyone here have gotcha's, experience and wisdom to share on this subject?

  • How to sleep computer via batch file?

    - by Saebin
    So I want to make a batch file that will sleep my computer after a period of time. The closest thing I have found is placing it in standby, but seems to work differently then the sleep button on my keyboard (longer bootup, doesn't wake on mouse click). Any ideas? Would it be easier in python or c#?

  • Android imageButton reset

    - by Dorin Rusu
    I have an app in which I need to use ImageButtons.The app has tabs, and when I click on a tab the ImageButton should be calling setBackgroundResource(), and when I click on another tab the imageButton should call setBackgroundColor() instead. The problem is that once the resource has been set (in my case a shape with round corners, a stroke and a transparent background), any use of setBackgroundColor() will just recolor the shape, and not the whole button. Is there a way to reset/clear the resource of an ImageButton?
