Re: How to convert pounds(Lb) to ounce(Oz) and Ounce(Oz) to Pounds(Lb) in C#.Net code

There's no real "logic part" in the operation: it's all about identifying what the conversion factor is.
I'm just guessing that you're a beginner and this is homework - so I won't explain how I'd do it (it probably involves some bits you haven't got to yet) and suggest that you pick a "base unit" and provide each possible "convertable unit" with a value which converts to that base unit. For example, if you select the kilogram as your base unit, then the conversion factor for 1lb would be 2.20462, and the conversion factor for 1oz would be 35.274
So to convert from "unit a" to "unit b" you multiply the number of items by the "unit b" conversion factor, divide that by the "unit a" convertion factor, and round it to perhaps 2 decimal places.
If the number of lb is 6.0, then you would convert to oz by:

6.0 * 35.274 / 2.20462 = 96.0002177246

Rounded, that's 96.00 oz.
So all you need to do is write a method which takes the selected unit text, and returns the conversion factor. Then call that twice, and you're pretty much there!

Try it: it's simpler than it sounds!

If you are really "working on unit of measure", you should take a moment to consider the longer term; e.g. a "weight structure / class".

The weight could have a "native" value, but would have methods for returning different UOMs: all ounces or grams; or pound / kilogram fractions; etc.

public class MyWeight {

   public decimal Weight { get; set; }
   public UnitOfMeasure Units { get; set; }

   public MyWeight( decimal weight, UnitOfMeasure units = UnitOfMeasure.Pounds ) {
      this.Weight = weight;
      this.Units = units;
   }

   public decimal InPounds( int decimalPlaces = 0 ) {

      decimal qty = 0M;

      switch ( this.Units ) {
         case UnitOfMeasure.Pounds:
            qty = Weight;
            break;
         case UnitOfMeasure.Ounces:
            qty = Weight * 0.0625M;
            break;
         case UnitOfMeasure.Kilograms:
            qty = Weight * 2.20462M;
            break;
         case UnitOfMeasure.Grams:
            qty = Weight * 0.00220462M;
            break;
         default:
            throw new NotImplementedException( string.Format( "{0} to Pounds.", Units ) );
      }  // end switch:

      qty = RoundUp( qty, decimalPlaces );

      return qty;
   }

   // Etc.

Hello engineers
 I'm Alireza Ketabdari,
I need a component for design of UI(user interface) with C# language that has a 2 main feature:
1- draw polygon and points and lines by setting location of these in code.
2- change location of these when program is running by click then moving the mousse(main feature).
 I could draw polygon and lines and points in panel component but Its locations couldn't change by click then move mousse.
If you know the component that provide me these two feature, you can help me very much and I appreciate you about your help and your attention.
 
      Tank You

It's called a "frame".

You "change locations" by "redrawing" the shapes and lines each time you have new coordinates.

Simply changing a "coordinate" usually has no "visual" affect unless you consider how the particular type of window you are working with "renders" its UI (i.e. measuring; layout; updates).

There is rarely a component that does all you require out of the box, and in the few cases it does, it is often rather expensive.

I'd recommend using a Panel

Member 12560979 wrote:

In that case, you can also create a new Panel (or PictureBox or whatever) and put it in that location, right? You'd need the coordinates (which you got), and add the thing to the controls-property of the panel. Things are easier if you give them different colors.

Something like;

var p = new Panel { BackColor = Blue, Location = new Location(x,y), Size = new Size(10, 10) };
Form1.MainPanel.Controls.Add(p);

This would give you a non-transparent panel on top of another. You could override the painting-event in the panel you added, only drawing the desired line. Moving the panel can be done by hooking the mouse-events of the child.

You could take a look at Paint.NET, Google for such examples and/or post more here if stuck Thumbs Up | :thumbsup:

Test Methods Are Grayed out

I have been banging my head for quite sometime over my unit test problem (MSTest VS2012). For some reason all of my test methods are grayed out with white exclamation points in front of them and they can not be selected.

When I do a Clean then Rebuild, the test methods could be selected again. However, when I click Run All, it hangs without crashing or giving me any errors. Eventually I just had to hit cancel.

Please suggest how to fix this issue, thanks.

Show message box on top from windows tray application.

Hi,

I have developed a RESTful windows tray application in C#. I access the public functions of this application from javascript via ajax call to http://localhost:8888/....

In the tray application i have referenced to a vb6 dll.

Now my query...
During the application's execution process, the vb dll shows a message box. Since I am calling the process from web browser, the message box appears behind the browser. Hence, The user has to press alt+tab to see the message, which is costing lot of time.

I want this message box to show up on top of all application all the time.

There is no form element in the tray application and vb6 dll.

Please help me to solve this issue.

Regards

Hi,

I have an requirement where we have some project under Target folder.. for these corrosponding target there will be .cs file in Unittest Folder(which will be created using tool).. based on no of count i can check whether unit test is done for that target.. but I want to check whether logic is implemented or not.

Thanks,
Amit Patel

well, you either need to

a) parse the .cs file to see if it contains the logic/whatever you're looking for (if its 'simple' you could perhaps use Regexes) or

b) compile the .cs file and use reflection to get the method signatures and compare those to a reference list

(there may be other ways, they strike me as the most obvious)

Also take a look at tools for calculating code coverage of tests. Though they won't tell you if your tests are useful, they will at least show you which lines of your code were reached during the execution of the tests.

Still not seeing a question in there. I see things you want to happen but no question as to what code you need help with, and by help I mean that you already have some code in place that isn't working that you need help with. Remember, we don't write entire sections of code for you.

on seeing all the articles I just had a thought of asking you guys for an article which crops the image before it is uploaded. You can see this example while uploading linkedin profile picture it will ask for crop before uploading. Many people will be grateful if any of you could work on it.
