  • FileUpload ASP.NET control not working under Windows 7

    - by YourMomzThaBomb
    I have a User Control that contains a System.Web.UI.WebControls.FileUpload control as well as a button to 'Submit'. When the button is clicked code similar to the following is executed: If FileUploadControl.HasFile Then 'Save the file and do some other stuff End If This code works just fine with Windows XP. However, if I run it from a Windows 7 64-bit machine using IE8 32-bit the HasFile property always returns false and nothing is saved?! Any suggestions/ideas would be greatly appreciated.

  • How to split HTML code with javascript or JQuery

    - by Dean
    Hi I'm making a website using JSP and servlets and I have to now break up a list of radio buttons to insert a textarea and a button. I have got the button and textarea to hide and show when you click on the radio button it shows the text area and button. But this only appears at the top and when there are hundreds on the page this will become awkward so i need a way for it to appear underneath. Here is what my HTML looks like when complied: <form action="addSpotlight" method="POST"> <table> <tr><td><input type="radio" value="29" name="publicationIDs" ></td><td>A System For Dynamic Server Allocation in Application Server Clusters, IEEE International Symposium on Parallel and Distributed Processsing with Applications, 2008</td> </tr> <tr><td><input type="radio" value="30" name="publicationIDs" ></td><td>Analysing BitTorrent's Seeding Strategies, 7th IEEE/IFIP International Conference on Embedded and Ubiquitous Computing (EUC-09), 2009</td> </tr> <tr><td><input type="radio" value="31" name="publicationIDs" ></td><td>The Effect of Server Reallocation Time in Dynamic Resource Allocation, UK Performance Engineering Workshop 2009, 2009</td> </tr> <tr><td><input type="radio" value="32" name="publicationIDs" ></td><td>idk, hello, 1992</td> </tr> <tr><td><input type="radio" value="33" name="publicationIDs" ></td><td>sad, safg, 1992</td> </tr> <div class="abstractWriteup"><textarea name="abstract"></textarea> <input type="submit" value="Add Spotlight"></div> </table> </form> Now here is what my JSP looks like: <form action="addSpotlight" method="POST"> <table> <%int i = 0; while(i<ids.size()){%> <tr><td><input type="radio" value="<%=ids.get(i)%>" name="publicationIDs" ></td><td><%=info.get(i)%></td> </tr> <%i++; }%> <div class="abstractWriteup"><textarea name="abstract"></textarea> <input type="submit" value="Add Spotlight"></div> </table> </form> Thanks in Advance Dean

  • One click to trigger several search forms?

    - by Christian
    Hello, I have 1 main search form with a submit button and several secondary search forms with submit buttons. What I would like to do is when I enter text and click on the submit button of the main search form, the same text gets copied in all of the secondary search forms and all the submit buttons of the secondary search forms get automatically hit. The HTML code for the mains earch form is shown below: <form action="query.php" method="get"> Search: <input type="text" name="item" size="30"> <input type="submit" value="send"> </form> One of the several secondary search forms is shown below: <FORM action="http://www.dpbolvw.net/interactive" method="GET" target="_blank"> <div style="float: left; padding: 0 3px 0 0;"> <INPUT type="text" name="src" size="9" value="<?php $input = $_GET['item']; echo $input;?>" style="width: 110px; height: 22px;margin:0; padding: 0; font-size:140%;"> </div> <div style="float: left; padding: 0 3px 0 0;"> <input type="image" name="submit" value="GO" src="http://images.guitarcenter.com/Content/GC/banner/go.gif" alt="Search" style="font-size:140%"> /div> <input type="hidden" name="aid" value="1234"/> <input type="hidden" name="pid" value="1234"/> <input type="hidden" name="url" value="http://www.guitarcenter.com/Search/Default.aspx"/> </form> Notice the php code that I put in the "value" field of the secondary search form: <?php $input = $_GET['item']; echo $input;?> This automatically copies the text that I entered in the main search form into the secondary search form. I thus figured out how to do that. The problem is to "simulate" an "Enter" keystroke or a click on the "GO" button with the mouse on the secondary search form when the user hits the Enter key or hits the "SEND" button with the mouse on the main search form. Thank you for your insight!

  • C#/.NET: TextBox is not 'focused' after a process was initiated

    - by eibhrum
    Hi, I am having a problem after opening the notepad once I click the button "btnSearch". The idea is that once I clicked the button 'btnSearch', the textbox 'txtSearch' should be 'focused' even after a process was initiated/opened outside the main window. Here's my code: private void btnSearch_Click(object sender, RoutedEventArgs e) { System.Diagnostics.Process.Start("notepad"); txtSearch.Focus(); // not working } Any suggestions?

  • Canceling BackgroundWorker within the Thread

    - by Mike Wills
    I have a longer running multi-step process using BackgroundWorker and C#. I need to be sure that each step is completed successfully before moving on to the next step. I have seen many references to letting the BackgroundWorker catch errors and canceling from clicking on a Cancel button, but I want to check for an error myself and then gracefully end the process. Do I treat it just like someone clicked the cancel button, or is there another way?

  • How can I make the text of a UIBarButtonItem wrap to two lines?

    - by bio18
    Some of the titles of view controllers in my UINavigationController are quite long, which makes the back button in the navigation bar of the next view controller in the hierarchy miss out some of the text, with a "..." instead. How could I make the text of the back button wrap onto two lines, as with "Now Playing" in the navigation bar of iPod.app? Thanks!

  • current location too slow for view

    - by Christian
    Hi, I make an App with a Map in the App and a button to change to the google.Map-App. The code for my position is: -(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { float avgAccuracy = (newLocation.verticalAccuracy + newLocation.horizontalAccuracy)/2.0; if (avgAccuracy < 500) { [locationManager stopUpdatingLocation]; locationManager.delegate = nil; } storedLocation = [newLocation coordinate]; The code for the view is: - (void)viewDidLoad { [super viewDidLoad]; UIImage *image = [UIImage imageNamed: @"LogoNavBar.png"]; UIImageView *imageview = [[UIImageView alloc] initWithImage: image]; UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithCustomView: imageview]; self.navigationItem.rightBarButtonItem = button; [imageview release]; [button release]; locationManager=[[CLLocationManager alloc] init]; locationManager.delegate = self; locationManager.desiredAccuracy = kCLLocationAccuracyBest; locationManager.distanceFilter = kCLDistanceFilterNone; [locationManager startUpdatingLocation]; mapView.showsUserLocation = YES; NSLog(@"storedLocation-latitude für MKregion: %f", storedLocation.latitude); MKCoordinateRegion region; region.center.latitude = (storedLocation.latitude + 45.58058)/2.0; region.center.longitude = (storedLocation.longitude - 0.546835)/2.0; region.span.latitudeDelta = ABS(storedLocation.latitude - 45.58058); region.span.longitudeDelta = ABS(storedLocation.longitude + 0.546835); [mapView setRegion:region animated:TRUE]; MKCoordinateRegion hotel; hotel.center.latitude = 45.58058; hotel.center.longitude = -0.546835; HotelPositionMarker* marker = [[HotelPositionMarker alloc] initWithCoordinate:hotel.center]; [mapView addAnnotation:marker]; [marker release]; } My problem: when the "viewDidLoad" start, the "storedLocation" is still 0.0000 it takes a bit longer to get the own position than to start the view. The Log for the "storedLocation" in the "viewDidLoad"-section is 0 while the Log of the "storedLocation" in the "-(IBAction)" when the map is visible contains the right values. How can I manage it to have my coordinates before the view load? I need them to center the view concerning the own position and the position given by me. MKCoordinateRegion region; region.center.latitude = (storedLocation.latitude + 45.58058)/2.0; region.center.longitude = (storedLocation.longitude - 0.546835)/2.0; region.span.latitudeDelta = ABS(storedLocation.latitude - 45.58058); region.span.longitudeDelta = ABS(storedLocation.longitude + 0.546835); [mapView setRegion:region animated:TRUE];

  • ASP.Net Checkbox value at postback is wrong?

    - by Duracell
    We have a checkbox that is initially disabled and checked. It is then enabled on the client side through javascript. If the user then unchecks the box and presses the button to invoke a postback, the state of the checkbox remains as checked on the server side. This is obviously undesirable behaviour. Here is an example. <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="testcb.aspx.cs" Inherits="ESC.testcb" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <script type="text/javascript"> function buttonClick() { var cb = document.getElementById('<%= CheckBox1.ClientID %>'); cb.disabled = false; cb.parentNode.disabled = false; } </script> <div> <asp:CheckBox ID="CheckBox1" runat="server" Checked="true" Enabled="false" /> <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="buttonClick(); return false;" /> <asp:Button ID="Button2" runat="server" Text="Button2" OnClick="button2Click" /> </div> </form> </body> </html> And the Server-side code: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace ESC { public partial class testcb : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void button2Click(object sender, EventArgs e) { string h = ""; } } } So we break at the "string h" line and check the value of CheckBox1.Checked. It is true, even if it is unchecked on the form.

  • ASP.NET RadioButtonList help. If I set a selectedItem, that item doesn't react to SelectedIndexChang

    - by Hcabnettek
    Hi Guys, I have a RadioButtonList on my web form. I have tried two different means to set the selected item. I have tried in the markup, and in code, like the Page_Load event. It sets and displays correctly. My problem is that the selected radio button no longer responds to the SelectedIndexChanged event. The other items works as expected and if I remove the code that sets the selectedItem, then the radio button works as expected. Is there any way I can set a radio button through code, and it still behaves as I would expect. I am guessing, if u force a button to be selected, then it doesn't change. Does anyone know how to rememdey this so I can default select it, but still have it behave the way I want? <asp:RadioButtonList ID="rblPaymentType" runat="server" AutoPostBack="True" RepeatDirection="Horizontal" RepeatLayout="Flow"> <asp:ListItem Value="benefit" Text="Benefit" Selected="True"/> <asp:ListItem Value="expense" Text="Expense" /> </asp:RadioButtonList> This lives inside an ascx which I have an event for public delegate void SwitchBenefitTypeHandler(object sender, EventArgs e); public event SwitchBenefitTypeHandler SwitchedBenefit; protected void Page_Load(object sender, EventArgs e) { WireEvents(); } private void WireEvents() { rblPaymentType.SelectedIndexChanged += (sender, args) => SwitchedBenefit(sender, args); } Then on the aspx, I wire a handler function to that event. if (header is PaymentHeader) (header as PaymentHeader).SwitchedBenefit += (paymentForm as PaymentBaseControl).Update; Finally the handler function public override void Update(object sender, EventArgs e) { if (sender is RadioButtonList) { IsExpense = (sender as RadioButtonList).SelectedValue == "expense"; UpdateCalcFlag(); UpdateDropDownDataSources(); UpdatePaymentTypeDropDown(); ResetBenefitLabels(); FormatAmountTextBox(); } } I hope that's enough code. Everything works great when I don't set the SelectedItem in the RadioButtonList but I need it set. Here's a link to someone with the same problem. It is ASP.NET AJAX related.

  • OpenGL suppresses exceptions in MFC dialog-based application

    - by Mikhail
    Hello. I have an MFC-driven dialog-based application created with MSVS2005. Here is my problem step by step. I have button on my dialog and corresponding click-handler with code like this: int* i = 0; *i = 3; I'm running debug version of program and when I click on the button, Visual Studio catches focus and alerts "Access violation writing location" exception, program cannot recover from the error and all I can do is to stop debugging. And this is the right behavior. Now I add some OpenGL initialization code in the OnInitDialog() method: HDC DC = GetDC(GetSafeHwnd()); static PIXELFORMATDESCRIPTOR pfd = { sizeof(PIXELFORMATDESCRIPTOR), // size of this pfd 1, // version number PFD_DRAW_TO_WINDOW | // support window PFD_SUPPORT_OPENGL | // support OpenGL PFD_DOUBLEBUFFER, // double buffered PFD_TYPE_RGBA, // RGBA type 24, // 24-bit color depth 0, 0, 0, 0, 0, 0, // color bits ignored 0, // no alpha buffer 0, // shift bit ignored 0, // no accumulation buffer 0, 0, 0, 0, // accum bits ignored 32, // 32-bit z-buffer 0, // no stencil buffer 0, // no auxiliary buffer PFD_MAIN_PLANE, // main layer 0, // reserved 0, 0, 0 // layer masks ignored }; int pixelformat = ChoosePixelFormat(DC, &pfd); SetPixelFormat(DC, pixelformat, &pfd); HGLRC hrc = wglCreateContext(DC); ASSERT(hrc != NULL); wglMakeCurrent(DC, hrc); Of course this is not exactly what I do, it is the simplified version of my code. Well now the strange things begin to happen: all initialization is fine, there are no errors in OnInitDialog(), but when I click the button... no exception is thrown. Nothing happens. At all. If I set a break-point at the *i = 3; and press F11 on it, the handler-function halts immediately and focus is returned to the application, which continue to work well. I can click button again and the same thing will happen. It seems like someone had handled occurred exception of access violation and silently returned execution into main application message-receiving cycle. If I comment the line wglMakeCurrent(DC, hrc);, all works fine as before, exception is thrown and Visual Studio catches it and shows window with error message and program must be terminated afterwards. I experience this problem under Windows 7 64-bit, NVIDIA GeForce 8800 with latest drivers (of 11.01.2010) available at website installed. My colleague has Windows Vista 32-bit and has no such problem - exception is thrown and application crashes in both cases. Well, hope good guys will help me :) PS The problem originally where posted under this topic.

  • Linking buttion to jQuery through service

    - by Ruddy
    I have a small problem that should be very easy to overcome. For some reason I cant work this out. So the problem is I cannot get a button to link to some jquery. My set-up is as follows (showing the relevant code): Default.aspx jQuery: function getContent() { var data = { numberID: 1 }; $.jsonAspNet("ContentService.asmx", "GetContent", data, function (result) { $('#content').html(result); }); } jQuery(document).ready(function () { getContent(); } HTML: <div id="content"></div> ContentService.vb Public Function GetContent(number As Integer) As String Dim sb = New StringBuilder sb.AppendLine("<table>") sb.AppendLine("<tr>") sb.AppendLine("<td class='ui-widget-header ui-corner-all'>Number</td>") sb.AppendLine("</tr>") sb.AppendLine("<tr>") sb.AppendLine("<td>" & number & "</td>") sb.AppendLine("<td><a href='#' id='test' class='fg-button ui-state-default ui-corner-all'><img src='" & Context.Request.ApplicationPath & "/images/spacer.gif' class='ui-icon ui-icon-pencil' /></a></td>") sb.AppendLine("</tr>") sb.AppendLine("</table>") Return sb.ToString End Function So that's the basics of what I have everything works but I'm not sure how to get the button (id='test') to get linked to some jQuery. I want it to be pressed and bring up a popup. I have tried to put the jQuery on default.aspx but this doesn't seem to work unless the button is place in the HTML on that page. $('#test').unbind('click').click(function () { alert('Working'); }); I'm sure this is easy to be able to do but I have been trying for a while and cannot seem to get it to work.

  • jQuery; combine user click and :checked

    - by user275074
    I have two blocks of code which basically check for 1) a click event on a radio button e.g. $("input[id='frmSkill']").click(function(){ //do something }); And 2) a block of code to check if a radio button is :checked, if so, then perform some actions e.g. if($("input[id='frmSkill']:checked").val()){ //do something }); What I'd like to do is combine the two in order to reduce the code as the actions performed under each are the same.
