VS 2010 Reverse Alphabetize A List?
Mar 11, 2011I have this coding for alphabetizing a list of the 50 states, but how would I reverse the process?
Private Sub btnAlphabetic_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAlpha.Click
lstOutput.Sorted = True
Dim highestIndex As Integer = lstStates.Items.Count - 1
For i As Integer = 0 To highestIndex
lstOutput.Items.Add(lstStates.Items(i))
Next
End Sub
Can't Get Number From List Box To Display In Reverse In Text Box
Mar 10, 2012Build a small application that fills a collection (list) with 10 sequential numbers, and then prints the collection(list) in reverse order, skipping every other member, until the entire collection has been displayed. For example, if the collection contained the numbers 1 through 10, they would print as:
10, 8, 6, 4, 2, 9, 7, 5, 3, 1 The print out should be in that order no matter what sequential numbers are in the collection (list). If it were 21 through 30, output would be 30,28,26,24,22,29,27,25,23,21 and so forth.
Note: you must use a collection - do not write down the numbers directly to produce the output. Loops should be employed but the loop control variable should be used as an index or subscript number. Your code should work even if I change the list of sequential numbers to something else. Remember that indexes count from 0 first -- the first item in a collection has index 0, the second item in a collection has index 1, and so forth.
I've got the first part of the problem, getting the numbers in the list box, done with no problem. It's the second part I am struggling with. I cannot get the numbers (I am using 1-10) from the list box to display in reverse order in an adjacent text box.[code]...

Exporting To Excel - Get Excel To Return Down A Row And Display The Next Product Within The List Box?
Apr 16, 2011I am building an ordering system for my job. The idea is that the customer will put in a stage name for an item. That stage name is then interpreted by the program.The product id and the amount the customer wants to order is placed in a list box on the form. There are a couple of buttons, ADD, REMOVE, CLEAR, and EXPORT. The user input is handled by input boxes. When the user pushes the EXPORT button, excel should open and list out the interpreted product codes with the corresponding amount to order. I can get excel to open, but I can not get excel to display more than one line. It will display the first product, but then it comes up with an unhandled exception.I can not figure out how to get excel to return down a row and display the next product within the list box.

View 1 RepliesAdding Data To List In Excel Without Inserting Row?
Aug 9, 2011I want to add data to a column in excel but I need to do it without inserting a row. I want to type the data in the top cell, execute an event, have all of the data shift down, and then clear the cell that I typed the data in. I can't insert a row because I have calculations that are based on each individual cell in the list in adjoining columns. I can get this to work by inserting a row but can't get the loop quite right without doing it this way.

View 3 RepliesList From OpenXML Excel Column Headers
Jun 22, 2010I am using VB.net 2008 express edition. I have figured out how to use some of the code snippets for the open xml sdk to create a drop down list of all the sheets in an excel file. I can also use the code snippet to get the value of an individual column header. What I want is a drop down list of all column headers. I could create an array containing the alphabet and loop through each column based on the alphabet letter in the array. I would then just exit the loop on the first column with no value returned for column header...but there must be an easy way to return all headers in one query of the xml.

Excel Scatterplot Chart From List (Of Decimal) Values - .NET?
