  • How to know when a download has finished?

    - by Eric
    Hello, Is there a way to tell if when a download has finished? That is, we allow users to download a report in PDF format. It takes about 3 - 5 seconds to start downloading and in this time, from click to end of download, show a wait state icon so that the user doesn't click multiple times. Thanks! Eric

  • Nintendo DS homebrew with Ada?

    - by TraumaPony
    Note: I know very little about the GCC toolchain, so this question may not make much sense. Since GCC includes an Ada front end, and it can emit ARM, and devKitPro is based on GCC, is it possible to use Ada instead of C/C++ for writing code on the DS? Edit: It seems that the target that devKitARM uses is arm-eabi.

  • Activity Indicator not displaying based on whether the UIWebView is loading or not...

    - by Jack W-H
    Hi folks Sorry if this is an easy one. Basically, here is my code: MainViewController.h: // // MainViewController.h // Site // // Created by Jack Webb-Heller on 19/03/2010. // Copyright __MyCompanyName__ 2010. All rights reserved. // #import "FlipsideViewController.h" @interface MainViewController : UIViewController <UIWebViewDelegate, FlipsideViewControllerDelegate> { IBOutlet UIWebView *webView; IBOutlet UIActivityIndicatorView *spinner; } - (IBAction)showInfo; @property(nonatomic,retain) UIWebView *webView; @property(nonatomic,retain) UIActivityIndicatorView *spinner; @end MainViewController.m: // // MainViewController.m // Site // // Created by Jack Webb-Heller on 19/03/2010. // Copyright __MyCompanyName__ 2010. All rights reserved. // #import "MainViewController.h" #import "MainView.h" @implementation MainViewController @synthesize webView; @synthesize spinner; - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { // Custom initialization } return self; } // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { NSURL *siteURL; NSString *siteURLString; siteURLString=[[NSString alloc] initWithString:@"http://www.site.com"]; siteURL=[[NSURL alloc] initWithString:siteURLString]; [webView loadRequest:[NSURLRequest requestWithURL:siteURL]]; [siteURL release]; [siteURLString release]; [super viewDidLoad]; } - (void)flipsideViewControllerDidFinish:(FlipsideViewController *)controller { [self dismissModalViewControllerAnimated:YES]; } - (void)webViewDidFinishLoad:(UIWebView *)webView { [spinner stopAnimating]; spinner.hidden=FALSE; NSLog(@"viewDidFinishLoad went through nicely"); } - (void)webViewDidStartLoad:(UIWebView *)webView { [spinner startAnimating]; spinner.hidden=FALSE; NSLog(@"viewDidStartLoad seems to be working"); } - (IBAction)showInfo { FlipsideViewController *controller = [[FlipsideViewController alloc] initWithNibName:@"FlipsideView" bundle:nil]; controller.delegate = self; controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } - (void)viewDidUnload { // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } - (void)dealloc { [spinner release]; [webView release]; [super dealloc]; } @end Unfortunately nothing is ever written to my log, and for some reason the Activity Indicator never seems to appear. What's going wrong here? Thanks folks Jack

  • Should Application_End fire on an automatic App Pool Recycle?

    - by Laramie
    I have read this, this, this and this plus a dozen other posts/blogs. I have an ASP.Net app in shared hosting that is frequently recycling. We use NLog and have the following code in global.asax void Application_Start(object sender, EventArgs e) { NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger(); logger.Debug("\r\n\r\nAPPLICATION STARTING\r\n\r\n"); } protected void Application_OnEnd(Object sender, EventArgs e) { NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger(); logger.Debug("\r\n\r\nAPPLICATION_OnEnd\r\n\r\n"); } void Application_End(object sender, EventArgs e) { HttpRuntime runtime = (HttpRuntime)typeof(System.Web.HttpRuntime).InvokeMember("_theRuntime", BindingFlags.NonPublic | BindingFlags.Static | BindingFlags.GetField, null, null, null); if (runtime == null) return; string shutDownMessage = (string)runtime.GetType().InvokeMember("_shutDownMessage", BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.GetField, null, runtime, null); string shutDownStack = (string)runtime.GetType().InvokeMember("_shutDownStack", BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.GetField, null, runtime, null); ApplicationShutdownReason shutdownReason = System.Web.Hosting.HostingEnvironment.ShutdownReason; NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger(); logger.Debug(String.Format("\r\n\r\nAPPLICATION END\r\n\r\n_shutDownReason = {2}\r\n\r\n _shutDownMessage = {0}\r\n\r\n_shutDownStack = {1}\r\n\r\n", shutDownMessage, shutDownStack, shutdownReason)); } void Application_Error(object sender, EventArgs e) { NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger(); logger.Debug("\r\n\r\nApplication_Error\r\n\r\n"); } Our log file is littered with "APPLICATION STARTING" entries, but neither Application_OnEnd, Application_End, nor Application_Error are ever fired during these spontaneous restarts. I know they are working because there are entries for touching the web.config or /bin files. We also ran a memory overload test and can trigger an OutOfMemoryException which is caught in Application_Error. We are trying to determine whether the virtual memory limit is causing the recycling. We have added GC.GetTotalMemory(false) throughout the code, but this is for all of .Net, not just our App´s pool, correct? We've also tried var oPerfCounter = new PerformanceCounter(); oPerfCounter.CategoryName = "Process"; oPerfCounter.CounterName = "Virtual Bytes"; oPerfCounter.InstanceName = "iisExpress"; logger.Debug("Virtual Bytes: " + oPerfCounter.RawValue + " bytes"); but don't have permission in shared hosting. I've monitored the app on a dev server with the same requests that caused the recycles in production with ANTS Memory Profiler attached and can't seem to find a culprit. We have also run it with a debugger attached in dev to check for uncaught exceptions in spawned threads that might cause the app to abort. My questions are these: How can I effectively monitor memory usage in shared hosting to tell how much my application is consuming prior to an application recycle? Why are the Application_[End/OnEnd/Error] handlers in global.asax not being called? How else can I determine what is causing these recycles? Thanks.

  • Updating Checked Checkboxes using CodeIgniter + MySQL

    - by Tim
    Hello I have about 8 check boxes that are being generated dynamically from my database. This is the code in my controller //Start Get Processes Query $this->db->select('*'); $this->db->from('projects_processes'); $this->db->where('process_enabled', '1'); $data['getprocesses'] = $this->db->get(); //End Get Processes Query //Start Get Checked Processes Query $this->db->select('*'); $this->db->from('projects_processes_reg'); $this->db->where('project_id', $project_id); $data['getchecked'] = $this->db->get(); //End Get Processes Query This is the code in my view. <?php if($getprocesses->result_array()) { ?> <?php foreach($getprocesses->result_array() as $getprocessrow): ?> <tr> <td><input <?php if($getchecked->result_array()) { foreach($getchecked->result_array() as $getcheckedrow): if($getprocessrow['process_id'] == $getcheckedrow['process_id']) { echo 'checked'; } endforeach; }?> type="checkbox" name="progresscheck[]" value="<?php echo $getprocessrow['process_id']; ?>"><?php echo $getprocessrow['process_name']; ?><br> </td> </tr> <?php endforeach; ?> This generates the checkboxes into the form and also checks the appropriate ones as specified by the database. The problem is updating them. What I have been doing so far is simply deleting all checkbox entries for the project and then re-inserting all the values into the database. This is bad because 1. It's slow and horrible. 2. I lose all my meta data of when the check boxes were checked. So I guess my question is, how do I update only the checkboxes that have been changed? Thanks, Tim

  • Is DiskDrive Signature unique?

    - by Ananth
    I am currently using WMI to query various details about the underlying hardware in order to uniquely identify a machine. To this end, I came across a field called "Signature" under "Win32_DiskDrive". Is this signature unique across machines (globally)? Can this be used reliably to identify the machine? Thanks, Ananth

    How do I use regular expressions and search and replace to turn this [UserID] = <UserID, int,> [UserID] = 123123 [UserID] = asd123123 into [UserID] = [UserID] [UserID] = [UserID] [UserID] = [UserID] In other words I want to take everything from left side of the line up to the '=' character and replace everything on the right side of the '=' with the match from the left side. We can assume a line break at the end of each line. What are my Find what: and Replace with: values?

  • One-Click Application Moving from WinForms to WPF

    - by Tyler
    I have a WinForms app that I recently re-wrote in WPF and I need to release to my end users. I'd like to be able to have the users go to the ClickOnce install point for the WPF application and have their WinForm application removed so they don't have both on their machine What's the best way (read: easiest for users) of accomplishing this? I have thought about creating an prereq command line app to detect the old version and uninstall, but would like to avoid having to write an something like that where it only get's run once.

  • Strange WndProc bug in .Net. VB.Net more specifically.

    - by Jules
    ETA: I use visual studio 2008 express edition. If I override WndProc and mess up somehow, I'll usually backtrack by commenting out code until it works again. The strange thing with WndProc though is you can strip it down to: Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message) MyBase.WndProc((m)) End Sub and it still throws the error. I have to remove the code and retype it in to reset the error. Anyone else experienced this?

  • Multiple constructors in C

    - by meepz
    Hello, I am making a string class in C as a homework and I was wondering how I can make multiple constructors with the same name given the parameter. The commented out area is what I tried to do with results from a few searches but that gives me errors. Pretty much I have some cases where I want to create my new string without any parameter then in other cases create a string with a pointer to character. Here is mystring.h #include <stdio.h> #include <stdlib.h> typedef struct mystring { char * c; int length; int (*sLength)(void * s); char (*charAt)(void * s, int i); int (*compareTo)(void * s1, void * s2); struct mystring * (*concat)(void * s1, void * s2); struct mystring * (*subString)(void * s, int begin, int end); void (*printS)(void * s); } string_t; typedef string_t * String; String newString(char * c); String newString2(); int slength(void * s); char charat(void * S, int i); int compareto(void * s1, void * s2); String concat(void * s1, void * s2); String substring(void * S, int begin, int end); void printstring(void * s); And here is mystring.c #include "mystring.h" String newString(){ } String newString(char * input){ //String newString::newString(char * input) { String s; s = (string_t *) malloc(sizeof(string_t)); s->c = (char *) malloc(sizeof(char) * 20); int i = 0; if (input == NULL){ s->c[0] = '\0'; return s; } while (input[i] != '\0') { s->c[i] = input[i]; i++; } //functions s->sLength = slength; s->charAt = charat; s->compareTo = compareto; s->concat = concat; s->subString = substring; s->printS = printstring; return s; }

  • matlab's phi symbol

    Not that significant, but annoying to no end. Why does matlab has no small phi (\varphi) symbol ? It has pretty much all other symbols LaTeX offers, but not this one. Why ? I may be wrong of course, in which case would be delighted if someone could prove me wrong...
