iphone - create UIImageView with portion of image file -

-

I am subclassing UIImageView to create a tile-based application. Basically, I have a single I am taking the image file and breaking it into pieces, and then I declare pieces in my tile ( UIImageViews ) so that they can be freely manipulated.

What is the best way to capture the part of an image and use it to attract UIImageView ? I thought of overriding the drawRect and using the CGAffineTransform , but it seems that there should be an easy way to do this, possibly a CGRect UIImage is sent to UIImageView , but I do not see the API for this.

here we go: 

  UIImage * img = [UIImage imageNamed : @ "MyImage.jpg"]; CGRTEMFframe = CGRAtech (X, Y, Tile Wide, Tile High); CGImageRef imageRef = CIMMage Crete with ImageInRect ([IMG CIMMGE], IMG Frame); UIImage * All Image = [UIImage imageWithCGImage: imageRef]; CGImageRelease (imageRef);

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...

How to Create Master-Details view using Asp.Net MVC framework -

-
I am evaluating the Asp.Net MVC framework for my enterprise application for the past few weeks. The one thing I'm trying to achieve is the master-detail view. As it is very clear that there is no vivestate and there is no postback. For example, now I am using the product, customer, order and order details table from the Northwind database and I am using the especial MVC. I want to make master-detail view. Basically I do not have to have separate ideas (pages of other words) for order and order details. View order and order details should be included. How should I design my controller and see how to get this functionality. Thanks & amp; Regards, Burhanuddin Ghee You want to write a domain-specific view-model class Adds an order and details from its order (I'm assuming that order-> order details are 1-> n relation, not familiar with Northwind): public class command view model (Public order order); Set;} public inenemable & lt; Order deletate & gt; ...
