do you people know the algorithm or in vb.net language ??
the number in array not always the same and so the total is. that is just an example.

Parameter name: length."This happens at "dblYearly Income." Also, how do I find out the number of occurrences of an item in an array? For instance, I have a Race combobox and need to find out how many occurrences there are for each race.Also, is there a way to count the number of occurrences of an array itself, I guess the upper index value?

View 7 RepliesI am trying to program a noise reduction algorithm that works with a set of datapoints in a VB.NET DataTable after being helped with my other question. Basically, I want to take two integers, a coordinate value (yCoord for example) and a threshold smoothing value (NoiseThresh), and take the average of the values in the range of (yCoord - NoiseThresh, yCoord + NoiseThresh) and store that number into an array. I'd repeat that process for each column (in this example) and end up with a one-dimensional array of average values. My questions are:
1) Did anything I just say make any sense ;), and
2) Can anyone help me with the code? I've got very little experience working with databases.

I need to write a program that requests a high number and a low number from the user, then the program searches the array and finds all elements within the two numbers. The program is used to search for past presidents, so if I type 43 for low number and 44 for high number, the program will display:
George Walker Bush
Barack Hussein Obama
I think I have an idea of how to search up to a certain point, but not to stop at a certain point....Here is the code that I have for that particular sub procedure:
Quote:
Private Sub btnDisplayRqst_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplayRqst.Click
Dim sr As IO.StreamReader = IO.File.OpenText("PRESIDENTS.TXT")

When i port it over to VB.NET, i encountered error message 'ReDim' cannot change the number of dimensions of an array. for the line highlighted in red. And I suspect that VB.NET need to always define the exact dimension of the array during the declaration. But for the function above, for the array of 'MyMat()', I do not know what is the exact dimension every time it runs, and that is why i need to check the dimension of the array.My question is do we have any solution in dealing unknown dimension array in VB.NET? As in VB6, we can just define Array() instead of Array (,) in VB.NET.

View 1 RepliesI am creating an application and I have the numbers 1 - 20. Each number represents a location. They are continuous. I need a way to find the closest number to a given location. For example if the event is in location 8 and there are 2 people who can attend who are in locations 6 and 10. Then zone 6 would be chosen as its closest and also the lowest. If I needed the next highest closest number then I could pull all of the numbers into an array and sort them and then pull out the one which is the next highest zone. However as I need to find the closest number which could be lower, im not sure how to achieve this.
