  • passing parameter to view in IOS after a button is pressed

    - by ghostrider
    I am new to IOS programming. So far I have been programming in android. So in android when pressing a button code for passing an argument would be like that: Intent i = new Intent(MainScreen.this,OtherScreen.class); Bundle b = new Bundle(); b.putString("data_1",data); i.putExtras(b); startActivity(i); and on the activity that opens, i would write something like this: Bundle b = getIntent().getExtras(); ski_center=b.getString("data_1"); what methods should I need to change in MainScreen and in OtherScreen in IOS to achieve the above. Basically I will have 3 buttons lets say in my MainScreen and each of it will open the Otherview but each time a different parameter will be passed. Foe example for each button i have code like these in MainScreen.m @synthesize fl; -(IBAction) ifl:(id) sender { } So I need your help in where to place the "missing" code, too.

  • How do I programmatically nullify a File Attachment in InfoPath Forms

    - by Doctor Zinda
    Howdy all, I'm running into a problem with some InfoPath C# code while trying to remove an attachment from a form. Basically the process is: User opens form User clicks button File attachment is cleared I've tried adding a blank attachment to my schema that never becomes populated, then setting the original field's value equal to that value by the method below. When debugging the form I catch an error: Schema validation found non-data type errors. Any tips here would be appreciated. public void BTN_ClearAttachment_Clicked(object sender, ClickedEventArgs e) { try { _OriginalAttachment.SetValue(_BLANK_ATTACHMENT.Value); } catch (Exception ex) { _ErrorField.SetValue(ex.Message + " : " + ex.StackTrace); } } Thanks, Dr Z Edit - P.S. I should clear up that both _OriginalAttachment & _ErrorField are both XPathNavigators, pointing at different schema elements. I've verified that these XPathNavigators are both pointing at valid schema elements.

  • Error safe/correcting resource identifier

    - by Martin
    The receiver is my website, the sender is the same but the medium is noisy, a user. He will read an alphanumeric code of length 6 and later input the same code to identify a resource. A good use for a error correcting code, I thought, and rather than do the research I thought I'd just put the question out there. Or I might be going about it the wrong way, since the situation is rather like sending a perfect dictionary along with every transmission. The requirements on the code are simply: 6 alphanumeric digits, to start with until I run out, anyway. If the user gets it wrong I should still be able to identify the right resource. No resource is preferable to the wrong one. Easy to code or have free libraries for .net Any suggestions?

  • Task.wait not working as I imagined

    - by user2357446
    I am trying to download a file, wait for the file to finish downloading, and then read the file afterwards. I have the following methods to do this: private async Task startDownload(string link, string savePath) { WebClient client = new WebClient(); client.DownloadProgressChanged += new DownloadProgressChangedEventHandler(client_DownloadProgressChanged); client.DownloadFileCompleted += new AsyncCompletedEventHandler(client_DownloadFileCompleted); await client.DownloadFileTaskAsync(new Uri(link), savePath); } private void checkUpdateButton_Click(object sender, EventArgs e) { Task task = Task.Factory.StartNew(() => startDownload(versionLink, versionSaveTo)); task.Wait(); if (task.IsCompleted) { checkVersion(); } } The checkVersion() method reads the file that was downloaded. This is throwing an IOException saying that the file is in use by something else and cannot be read. I thought that having task.Wait would prevent the rest of the method from executing until the task was finished?

  • how use ASP.NET_SessionId cookies to check timeout for 2 different web applications

    - by user553858
    Hi All I am developing 2 web applications based on "ASP.NET_SessionId" cookies to check session timeout and also to logout : protected void Session_Start(object sender, EventArgs e) { if (Context.Session != null) { //check the IsNewSession value, this will tell us if the session has been reset if (Session.IsNewSession) { string cookie = Request.Headers["Cookie"]; // Code that runs when a new session is started if ((null != cookie) && (cookie.IndexOf("ASP.NET_SessionId") >= 0)) { if (Request.QueryString["timeout"] == null || !Request.QueryString["timeout"].ToString().Equals("yes")) Session.Abandon(); Session.Clear(); Response.Redirect("Login.aspx?timeout=yes"); } } } } This works fine for my first application. When implementing the same logic for the 2nd application when I press logout in one application, the second application is redirected to the login page. How can I fix this? Best regards

  • navigation between screens Iphone programming

    - by Sephy
    Hi, I don't know if my question will be clear or not, but i'm starting basic stuff with iphone programming, and i'm trying to understand how to go from a screen to another. lets say i have a screen with a "next page" button and another page with a "return" button. I have a general idea of how to do this, but I don't know how to put it together. I think I need an IBAction method for each button, and in each method a navigation controller with pushViewController. So far, i've tried the following code, but even if it compiles properly and runs when i push the button, there is no change of screen... -(IBAction) toNext(id)sender{ NSLog(@"before code"); NextViewController *nvc = [[NextViewController alloc] initWithNibName:@"NextView" bundle:nil]; [self.navigationController pushViewController:nvc animated:YES]; [nvc release]; NSLog(@"after code"); } If someone had a nice tuto for me, it could be of some help... thx
