Looking at that, I had to wonder if you were trying C#6 property syntax and just forgot the => instead of =.

how to get the longest distance between equal number in the array using c#
|
|
|
|
|
Do you expect other's to write the code for you? It ain't work so here.
But it is quite simple. Give it a try:
Iterate over the array items using another iteration for each item looking for equal numbers. With equal numbers get the distance and check if it is larger than the previously detected maximum distance.

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.
Try it yourself, you may find it is not as difficult as you think!
But without giving you any code, I'll tell you how I'd do it: I'd create a struct to hold each distinct value and a sorted list of indexes in the array. I'd then fill out a collection of such structs - one for each distinct value in the array - and traverse the collection when complete to find the largest difference in indexes.
If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!

We do not do your HomeWork.
HomeWork is not set to test your skills at begging other people to do your work, it is set to make you think and to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.
Any failure of you will help your teacher spot your weaknesses and set remedial actions.
So, give it a try, reread your lessons and start working. If you are stuck on a specific problem, show your code and explain this exact problem, we might help.
As programmer, your job is to create algorithms that solve specific problems and you can't rely on someone else to eternally do it for you, so there is a time where you will have to learn how to. And the sooner, the better.
When you just ask for the solution, it is like trying to learn to drive a car by having someone else training.
Creating an algorithm is basically finding the maths and make necessary adaptation to fit your actual problem.

Hi, I'm creating a custom VScrollBar and I have problem getting the exact Y position of the thumb like the Windows.Forms.VScrollBar, I have searched online and I found some examples of custom scrollbars like:
How to skin scrollbars for Panels, in C#[^]
Custom Drawn Scrollbar[^]
The problem with these examples are that they don't get the exact top position of the thumb comparing to the windows scrollbar. I am getting a Top position that while scrolling becomes less than the real position
Doesn't anyone know how to calculate this?

How are you calculating it?
|
|
|
|
|
I'm calculating it like this
decimal ratio = (decimal)((ClientRectangle.Height) - 2 * topButton.Height - ThumbSize()) / (Maximum - Minimum);
int thumbTopPosition = (int)((Value - Minimum) * ratio) + topButton.Height;
|
|
|
|
|
And what is wrong with the result?
|
|
|
|
|
the problem is that the Y position I get is smaller than the position of the Windows Scrollbar.
I tested my custom scrollbar with the Windows scrollbar with the same Maximum, Minimum, LargeChange and SmallChange, and when I get a Y position of 45 the other has a Y position little bit bigger than 45. The difference between the Y positions gets bigger as a set the Maximum value bigger.
|
|
|
|
|
I can only assume that your calculation is missing or adding something that Windows includes/excludes.
|
|
|
|
|
I'm thinking exactly the same. I'm missing something that windows includes. I hope I can figure it out.
|
|
|
|
|
and what is in the ThumbSize method?
I would avoid the decimal type, what you need is either float or double, since ratio could be a very small number; decimal is fine for monetary amounts, not for arbitrary scaling. Have you ever looked at the actual values while debugging?

Hi Richard, all is fine, except for the scrollbar never reaching the bottom...
|
|
|
|
|
|
this is what is inside thumbSize. it works pretty well.
int trackHeight = (Height - (2 * topButton.Height));
int thumbHeight = (LargeChange / Maximum) * trackHeight;
I changed the values from decimal to float I'm still getting the same result. the thumb never reaches the bottom. I think there must be something else to add to the thumb position than I'm not adding.
|
|
|
|
|
If you can't reach the scroll's bottom, it means ratio is too small. As your math seems OK, I can imagine only two reasons:
1. a rounding down error, probably caused by a bad choice of data type (such as decimal only offering two fractional digits);
2. ThumbSize() returing too large a value; so please check and/or provide the exact code for that method.
Suggestion: take one example, note all the numbers, compare what they are (from logging or interactive debug session) with what they should be (manual calculation), you then should be able to see the error right away!
PS: ClientHeight isn't always the right value, e.g. when a HScrollBar appears, it reduces the VScrollBar's height!
