VB / Excel Question
Greetings,
I am able to read the data from an xlsx file into textboxes into vb. What I would like to do is read the .xlsx file into a listview so that the data could be sorted by highest value to lowest value. Then have it export it back out to a new excel file, is this possible? Could someone help me with code, it's the only part im stuck on. I currently have the .xlsx data goign into textboxes, but think it might not be the greatest method.

Wouldn't it be easier to load the data into a List(Of Integer)? Then call the Sort method on the List and send the data back.

Yeah, im a newb so I started the hard way i guess. If you could help with that I would be so releaved. Having 125 textboxes is not fun lol.
Dim myInts As New List(Of Integer)
When looping thru your range you simply use the add method. Then after the loop you use myInts.Sort
If your going from highest to lowest then iterate backwards thru your List
For I As Integer = myInts.Count - 1 To 0 Step - 1
Excel cell = myInts(i)
Next

Yep im totally lost, not sure even what the above does sadly.
How are you currently looping thru the excel file?

Just haveing vb read 1 cell at a time, and then putting it's value inside of a textbox.

after opeinging the excel file do this
drosiond1.Text = oSheet.Range("Z3").Value
drosiond2.Text = oSheet.Range("Z4").Value
drosiond3.Text = oSheet.Range("Z5").Value
drosiond4.Text = oSheet.Range("Z6").Value
drosiond5.Text = oSheet.Range("Z7").Value
drosiond6.Text = oSheet.Range("Z8").Value
drosiond7.Text = oSheet.Range("Z9").Value
drosiond8.Text = oSheet.Range("Z10").Value
drosiond9.Text = oSheet.Range("Z11").Value
drosiond10.Text = oSheet.Range("Z12").Value
drosiond11.Text = oSheet.Range("Z13").Value
drosiond12.Text = oSheet.Range("Z14").Value
drosiond13.Text = oSheet.Range("Z15").Value
drosiond14.Text = oSheet.Range("Z16").Value
drosiond15.Text = oSheet.Range("Z17").Value
For Each n In Range("Z
myInts.Add(n.Value)
Next n

Cool, how would I then take the integers and put them into this datalist. Trying to word this the best I can and thaks for taking the time to help a nub lol.
I guess you have already got the Excel data to Listview now. Can you not use ADO.NET to read from Excel and then display the results in a DataGridView? Let me know if interested.
In my example I am adding each interger into the List(Of Integer) which is a collection. After you fill it with the loop you call the Sort method. Now you have a collection of Integers that are sorted from lowest to highest. Now loop thru this List and place them into your excel range.
Dim k As Integer
For Each j As Integer In myInts
oSheet.Range(COL + k, ROW).Value = j
k += 1
Next
Dim k As Integer
For Each j As Integer In myInts
oSheet.Range(COL + k, ROW).Value = j
k += 1
Next
Why not use ADO???

I am interested in this ADO, but not sure how it works or even to code it. I made it this far using other solutions that were solved to get this far.
