But is it not strange that this works? I mean when removing with chart.MouseMove -= new MouseEventHandler(chart_MouseMove); it 'removes' an instance created with new and which has not been added yet. I'm confused...

SFSG, but why do you think your sql statement does make a relation between 'Hemil Gandhi' and 'Gandhi Hemil'?

0x01AA 14-Jun-24 13:37pm View

I don't get the point, sorry.
Does 'ORDER BY #' where # is the field number (1...N) works or not? Btw. 'ORDER BY #' can be used in any SELECT in most SQL Servers, also for not UNION SELECT statements.

0x01AA 14-Jun-24 9:22am View

Especally for UNIONS it is sometimes better to simply use the 'field number' in the order statement.

E.g. 'SELCT FA, FB, FC FROM XYZ ORDER BY 2' will order by the field value 'FB'

Most probably you have reasons why you use JS Canvas.

Only as a hint: Using SVG can make your life more easy. With SVG you can define a so called 'viewBox'. This frees you from the constant conversion and rethinking of a Cartesian coordinate (with origin in left bottom) system to screen coordinates (with origin left top). Also for scaling you don't have to bother, once the 'viewBox' is defined.

I hope you can understand my cryptic English ;)

0x01AA 23-Apr-24 9:55am View

I expected this will come ;)

start angle: Math.asin(opposite/hypotenuse)
end angle: pi - start angle

where in the formula above:
opposite is b/4
and hypotenuse is the radius of the circle, therefore b/2

[Edit]
(b/4)/(b/2)= 2/4= 0.5
Start: asin(0.5) = 0.5236
End: pi - 0.5236= 2.618

[Edit1]
Taking into acount the inversed y axis it should than be more:
ctx.arc(100, 75, 50, -0.5236, 0.5236-Math.PI, true);

See here for more background:
Trigonometry - Wikipedia[^]

0x01AA 23-Apr-24 7:51am View

Without guarantee and not verified, but the idea should be ok:
You know the vertical distance from the center of the circle where it crosses the top line: b/4
You know the raduis of the circle: b/2
With this you have the horizontal distance where the circle crosses the top line.
Pyhtagoras: r^2 - (b/4)^2= (b/2)^2- (b/4=^2= b^2/4 - b^2/16= 4b^2/16-b^2/16= 3b^2/16
Horizontal distance of the crossing point from center= Sqrt(3b^2/16)

Nope:
COLREF do have always the byte order BGR (ABGR), and assigning it to and from an int does note change it.

If you have your file open in vs, then have a look at right bottom of the edit window, where you see line number, column etc.
There you should also see 'CR'. Click on 'CR' and change it to 'CRLF' and save the file ;)

FYI, below my ugly approach,at least to determine the Groups with a thing like SetId.

As mentioned, I don't like it. It works, but I assume only by chance. This because it is not possible to have a 'order by' in the select statement for the 'STRING_AGG' and furthermore it is simply ugly and has many restrictions and does not really follows the set theory on which SQL is based.

WITH Bom AS (
SELECT  DISTINCT
	BomId
  FROM BomPositions
),
BomSetId AS (
   SELECT
      Bom.BomId,
	  (SELECT STRING_AGG(BomPos.MaterialId + '_' + FORMAT(BomPos.MaterialQuantity, 'N2'), ',') 
      FROM BomPositions BomPos 
	  WHERE  (BomPos.BomId = Bom.BomId)
	  AS SetId
   FROM Bom 
)

SELECT 
	DISTINCT SetId 
FROM BomSetId
ORDER BY SetId;

Thank you for your interest .
My 5 for your help, it gives me a direction and ideas.

The result is unfortunatelly not what I expect.
It ends in 12 Groups wehere I expect 3 and also 30 reuslt lines instead of 7.
Anyway wow! Without testing, no syntax error in your sql statement ;)

Btw. My current appraoch is to create a 'Set Id' with the help of 'STRING_AGG'. It works, but I don' like it. It is far away from SQL's set approach.

0x01AA 28-Mar-24 16:07pm View

a.) Try to understand the request
b.) Learn about the tool e.g. c++, with which you have to solve it
c.) Abstract and solve it with that tool

I assume in UK it is also dd-MM-yyyy and I assume HackerRank runs on a US system. In case all my assumtptions are correct, then one needs to use DateTime.ParseExact instead of DateTime.Parse.
Now, because of my limited English, I'm not able to answer this in an understandable way :-)

0x01AA 26-Feb-24 13:22pm View

I mean it will show the correct result on your system. On what OS HackerRank runs I dont' know.

To be on the safe side then use explicit format definition for DateTime.Parse(date);

Something like this:
DateTime A = DateTime.ParseExact(date1, "dd-MM-yyyy", null);

0x01AA 26-Feb-24 13:04pm View

I would guess it is maybe something with 'dd-mm-yyyy' vs. 'mm-dd-yyyy'
I'm pretty sure your code will print 5 when you enter "08-02-2025 09-04-2025" ;)

It makes no sense deleting pointers after adding them to the vector. You should only delete the pointers when you no longer need m_vBol. Means, you iterate over all items in m_vBol and delete them

0x01AA 21-Feb-24 15:57pm View

And can you please confirm, same is also in original version and not caused by my addition of 'code tag'...

0x01AA 29-Jan-24 7:02am View

Did you implemented the ButtonClick method I mentioned in the code above?
Then it should be a line series....

In the designer you will see a bar graph by defualt. But you can change that also:
Click the graph
In the property window for the graph there will be a property Series.
Click on that and the series editor will be opened.
Check for the series change the property to 'Line' (SeriesChartType.Line)

Some background from my side: I'm working meanwhile for about 35 years with industrial spectrophotometer from Agilent, Datacolor, XRite, Minolta, Hunterlab, Perking Elmer, ...

Wow! Cool!
If you build this, than a .net winform app would be easy for you ;)

0x01AA 28-Jan-24 9:45am View

I really suggest to switch to .net. It is very simple to do a WinForm application.
You simply put a graph onto a form and set e.g. the properties for the graph series in the vs designer.
Yes you can do scientific graphics. Most examples shows bar graphs (don't ask me why). But as mentioned, set the property of a series from bar graph to line series and you can easely show yoour spectral graph e.g. from 360-750 nm

Btw. may I ask you which brand/model of spectrophotometer you are using?

A brute force solution would be:
You calculate every possible distribution of the M coins into the N bags.

Not nice, but maybe a solution.

0x01AA 28-Dec-23 11:39am View

I need time to think about it. Meanwhile I hope that after clarification of the target, some others here will hook in.

It looks pretty like a optimization request. The brute force solution will be to solve it with a downhill algorithm. But I think it is overkill. As I mentioned I need some time.

And you are very welcome with a question that challenges the brain ;)

0x01AA 28-Dec-23 11:16am View

In my words (keep in mind I'm not native English):
Distribute the M coins with individual values into N (e.g. here N = 4) pots in a way that every of the N pots contain nearly the same quantity.

In other words:
a.) We have M coins with individual values. Let us call the sum of them is SM.
b.) We have N pots
c.) The optimal distribution of the M coins into the N pots is when every pot holds SM/N 'coin values'

Correct?

'raw pixels similar to ByteBuffers in Java' is very general. A ByteBuffer can contain any information, not just bitmaps.

If you like to represent a bitmap in a 'ByteBuffer' - which you can ultimately simply display as a bitmap - you have to put a little more thought into it. In particular about things like bit/pixel, alpha chanel y/n etc. Also, for example, under Windows the native format is BGR...

The pragmatic approach will be: ABGR
An integer (4 bytes) containing the informat about
A: Alpha Chanel (transparency)
B: B RGB Chanel
G: G RGB Chanel
R: R RGB Chanel

How this is related to your question? I mean updateUIBarCode is called in case else if (e.KeyCode == Keys.Enter || e.KeyCode == Keys.Return) but you are claiming that simple numbers are not shown in a way you expect ;)
Maybe you should show also the code for updateUIBarCode even I think this will be out of question...

One easy way (maybe not the cleanest) is to implement a method DoException(string message) which throws then an exception based on the value of m_WithException. At least this way you get rid of all the 'if' in the code.

In c++ there is a 'logic'. The logic is to evaluate parameters from right to left. But of course, I would not rely on, that every compiler does it the same way.

0x01AA 24-May-23 13:45pm View

No problem. But you mentioned you tried TinyExpr. That means, you can use it and write the code to varying the variable in a loop 'in a structured way' and let TinyExpr evaluate. That comes nearly to a solver.
Sorry for my English...

0x01AA 23-May-23 15:10pm View

There are a lot, I'm sure.
But meanwhile I had a closer look to your equation and if '%' means Modulo then of course there will no solution. This because (x+38)%4 has no chance to give a reminder of 30 ;)

0x01AA 23-May-23 14:25pm View

There are a lot of solver examples: Google for "solver c++". Solver in very easy words means for your example to solve the equation (x + 38)%4") - 30 = 0 by varying parameter x (also called root search).

Looks like you mix up the things....
In your main you instanciate parent_class parent; and derived_class derived1; and I think that ends in your confusion.
These two instances are completely unrelated instances and each of these instances hold it's _own_ data.

The instance parent has private1 equals to -1 and private2 equals to -12.
While the instance of derived1 has the values private1 of 20 and private2 of 32 (both stored in base class/in other words members of the base class) and additinal the member private3 of 45, member of the dreived class.

Again: The instances of parent_class parent; and derived_class derived1; are completely unrelated variables.

0x01AA 10-Apr-23 11:21am View

Yes but you don't set it to upwards when last direction was downwards.
And again: You don't start the levator in case it goes downwards.

0x01AA 10-Apr-23 11:12am View

On a first glance:
a.) In button2_Click_1 in case it goes down you don't start the elevator in case if(diff<0)
b.) In the same method make sure to always set the direction upwards to the correct value. This wheter it goes up or down.

0x01AA 10-Apr-23 9:54am View

For this you have the methods
