c# - Why does Decimal.Divide(int, int) work, but not (int / int)? -

-

How two split 32 bit int numbers (int / int) gives me 0 , But if I use decimals Dive () I get the right answer? I'm not the AC # man in any way.

int is an integer type; Splitting of two ints causes an integer partition, i.e. partial part is deducted because it can not be stored in the result type (also int !) By contrast, decimals , a partial piece is found. By introducing decimals. Divided , your int arguments is converted into a decimal s.

You can apply a non-integer 

  int a = 42; For the floating point type, explicitly casting at least one argument, the partition on the  int  argument. Int b = 23; Double result = (double) A / B;

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; ...
