I want to sort a decimal array (currency with the places). I'm sure that I could find a bubble sort and modify it to suit my needs but it would seem that there would be a clean solution out there so I don't have to reinvient to wheel.
View 3 RepliesI have a datagridview which is bounded to a table m_table constructed in my code. A column named price has decimal type.
DGV.DataSource = m_table
DGV.Columns(columnPrice).ValueType = System.Type.GetType("System.Decimal")
All prices are in decimal. But I found that when clicking the column header of DGV, the price column is sorted like a string. For example:
9.0, 13.5, 8->13.5, 8, 9.0
But I want sort numerically, that is 8,9.0,13.5
I wonder why decimal type cannot be sorted numerically. How to achieve this?
I'm trying to sort an array based on a structure but whenever I do this, it basically erases all the data in the entire array.I have verified that the array is populated correctly, it is when using array.sort that everything returns blank.

I am trouble in sorting 2 dimensions array in vb.net. One row has 5 columns. Original array have 3000 rows.How can I get the effective sorting with pdtId. I tried to find googling, cannot get the right answer to me.
(0, 0) = pdtId "string"
(0, 1) = brand name
(0, 2) = category Id
(0, 3) = url
(0, 4) = date

I'm trying to bubble sort an array then display it in a list box. When I click the button the program crashes.
Here is my code:

If Not TextBox1.Text = "" Then
ListBox1.Items.Add(TextBox1.Text)

I have a 2 column database....looks a little something like this:
Column A Column B
972CL 86.20716105
972CL 58.71034089
972CL 64.15368376[code].....
In column A there are 5 different variables (i have shown 3)....My goal code a macro to sort these by column A, calculate the average of the corresponding values in column B and ultimately end up with 5 variables that are the names of column A. e.g
972CL = average of all the 9721CL variables
972V = average of all the 972V variables
A caveat is that i will not know the names of the variables...i'm not sure if this code below is the right way:
For Row2 = 1 To 100
If Worksheets("Sheet2").Cells(Row2, Col2).Value = Worksheets("Sheet2").Cells(Row2 + 1, Col2 + 1).Value Then
testno = Worksheets("Sheet2").Cells(Row2, Col2).Value[code].....

sorting list of files in a folder. Below is a snipet of code from a program. The logic is dependant on the files coming in in alphapetical order. I did post about this earlier but I got pulled away and did not get a chance to follow the thread all the way through. The code is complete and it works. However I know it is not guarenteed to pull in alphabetical order so as my final step I wanted to sort the list of files. I thoughr using the array.sort command might work but I am not sure how to use it.

I am trying to sort an array of ListViewItems, here is my code for setting is up:

I know I can have the ListView be sorted but I want the item "All" to stay at the top. I have tried sorting the array with:

I also tried:
vb.net
ListViewItemArray.Sort()
But it says there is invalid number of arguments. Is it possible to sort this array or is there an easier way to accomplish what I am trying to do?
