Convert A Double X To A Decimal Y?
Oct 5, 2011Let's say I want to convert a Double x to a Decimal y. There's a lot of ways to do that:
1. var y = Convert.ToDecimal(x); // Dim y = Convert.ToDecimal(x)
2. var y = new Decimal(x); // Dim y = new Decimal(x)
3. var y = (decimal)x; // Dim y = CType(x, Decimal)
4. -- no C# equivalent -- // Dim y = CDec(x)
Functionally, all of the above do the same thing (as far as I can tell). Other than personal taste and style, is there a particular reason to choose one option over the other?
EDIT: This is the IL generated by compiling the three C# options in a Release configuration:
1. call valuetype [mscorlib]System.Decimal [mscorlib]System.Convert::ToDecimal(float64)
--> which calls System.Decimal::op_Explicit(float64)

C# - Convert MBF Single And Double To IEEE?
Jun 4, 2010Follow-Up available: There's a follow-up with further details, see Convert MBF to IEEE.
I've got some legacy data which is still in use, reading the binary files is not the problem, the number format is. All floating point numbers are saved in MBF format (Single and Double). I've found a topic about that on the MSDN boards but that one only deals with Single values. I'd also would like to stay away from API-Calls as far as I can.
Edit: Just in case somebody needs it, here is the VB.NET Code (it's Option Strict compliant) I ended up with (feel free to convert it to C# and edit it in):
''' <summary>Converts a MBF Single to an IEEE Single</summary>
''' <param name="src">The MBF Single value</param>
''' <returns>The converted IEEE Single value</returns>

Convert Double To A Timespan (date)
Sep 23, 2009Let just say I have an Integer like 10,000 (that's the VALUE in want to reach). So, I have another integer like 2500 (that's my current VALUE). Third I have another Integer about 350 PER HOUR. To reach 10,000 I need 7,500 (well I already have 2,500). How long must I wait to reach the 10,000 when the increase is about 350 a Hour. Okay, that's easy: 7,500 / 350 = 21,428571 Hours. BUT how can I convert this double to a timespan? Or how is it possible to add this double value to the current Date to get the Date + Time when I reach the Value?

Flickering - Double Buffered Picturebox - Not Double Buffere - Black Screen With The White Lines
Nov 17, 2010I have a htpc project that I am working on. The main program loads dll plugins which are basically other win forms. On each of these forms, including the main program, I use a picturebox (a double buffered picturebox) for the background image and then draw everything on it by hand. Whenever I load the form from the dll and show it, I get a weird flicker. It looks like it is the previously used double buffer. Is there any way to clear the background double buffer before the flicker? Or am I going in the wrong direction?
Here's a couple of videos of the problem:
