iphone - Code not executing as expected when loading URL into UIImageView -

iphone - Code not executing as expected when loading URL into UIImageView -

I'm having trouble with my code, it seems that it never gets right.

I have tried many things from UIActivity, Slider, UITextViewer ... but it never changes,

The code runs from xCode using a Navigation based application LoadingTview is a text view,

The problem is, see what the method of loading is, which never works, it always hangs, the user presses a button, and this code executes is. LoadingTueview is a textview that is saying "loading", with alpha of 0.4, so that it will be loaded while downloading the website originally, people know its loading.

Even I tried the ideas but there was only one problem.

How can I make progress?

  loadingTview.hidden = false; Today = [NSDT Date]; DateFormat = [[NSDateFormatter alloc] init]; [DateFormat setDateFormat: @ "dd-MM-yyyy"]; Date string = [datefirm string string: today]; If (pageand == @ "page 1") {NSString * url = [NSString stringWithFormat: @ "http://www.imagegoeshere.com/%@.jpg", date string]; ImageURL = [NSURL URLWithString: url]; ImageData = [NSData Datatyh content of URL: URL]; Image = [UIImage imageWithData: imageData]; Fullscreen Image Image = image; LoadingTview.hidden = true; [Navigation controller Push ViewController: Animated vFullscreen: Yes]; }

I'm not completely sure what the problem is, but I think that When you look at scene 2 to 3 it looks at 3, until the image loads before actually opening View3 to show the loading screen, okay?

If this is the case, what do you want to do is load your image in a different thread so that the loading screen can not be stopped by showing the loading screen.

Take a look (though there are cleaner / better ways to do this).

Actually do this in the controller of 3:

  - (zero) viewDidoadload {// & lt; First, show your 'Loading ...' screen here & gt; // Then create a thread to load the image: [NSThread detachNewThreadSelector: @selector (loadImage) toTarget: self withObject: zero]; } // Then define the loading method anywhere in the same class: - (zero) load image {// Remember to create a new autorovet pool for this thread //

  If you do not have a problem, please provide more details about what is actually happening and what the problem is. 
  Good luck.

Unable to get a fresh ASP.NET MVC project running with Visual Studio
2008 -



    This is a very basic question. I'm asking this silly about this, but I'm stuck something else and hopefully That something here can save me some time. So I open VS2008, to download the new ASP.NET MVC web application and click OK I want to prepare a test project. I debug my new MVC project to hit F5 then I enable the debugging to the web. I choose to modify the config file. It goes where I get a page load error.   Firefox can not establish a connection to the server on the local host: 57323.   Do I have to do something special for Vista? Or I should do something with IIS   Thanks for helping a noob   6/30/2009 update   OK, I think that I VS2008 may need to be reinstalled with the ASP.NET Development Server port. I have tried to do everything that I have suggested. I've marked Default.aspx as the start page. I tried to open it in Firefox / IE 8 / and Chrome. I tried to uninstall / reinstall ASP.NET MVC, which was not working. I tried telnetting with Putin with a local ho...






delphi - Mouseover hint for TChart series value -



    I am using a TChart in Delphi 7, and I want to display charts sometime. I am using the following code to set the chain value to a database query:    chart1.FreeAllSeries; Chart1.SeriesList.Clear; Chart1.AddSeries (TBarSeries.Create (self)); TBarSeries (chart1.Series [0]) BarStyle :. = BsRectGradient; Stop starting with Query 1; Executed; While EOF does not start chart1.Series [0]. Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End;    Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar.   Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...?      This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you:    Process TForm...






sql - Incorrect syntax near the keyword 'table' -



    I'm getting this error what I'm doing is trying to get data from a table and a db and Keep it in another DB and table. The tables are not exactly the same, I am using a FETCH cursor, so I get the first line from the DB1 table and then keep each column value in the declared variable. Then I run an assembly statement in db2 table and get the next value. All of these are working properly because it runs properly, but in the end I get this error,   Wrong syntax near the keyword 'table'.   In the entire transaction details, an attempt / catch with the error of expression in the Cat block, apart from this, I do not know what is the reason for it.   Here is the code    added to prevent additional result set at SET NOCOUNT - Interfering with the SELECT statement.
