1.list boxes in visual basic .net

I am coding an application in .net using a list box.  I have the listbox 
property set to MultiSimple.  I can click on several different selections (or 
all) in the list box, but only the first one is the "active" one.  What I 
want to do is create an application that someone can order menu items from(I 
am a beginning .net programmer).  Here is my code that can allow one 
selection:
'defines structure
    Structure MenuItems
        Public strItem As String
        Public decPrice As Decimal
    End Structure
    'declare module level array 
    Dim mitmMenuItems(7) As MenuItems
    Private Sub frmsmoke_Load(ByVal sender As Object, ByVal e As 
System.EventArgs) Handles MyBase.Load
        'fills mitmmenuitems array with menu items and prices from 
        'a sequential access file
        'declare variables
        Dim sreStreamReader As IO.StreamReader
        Dim intNumber As Integer

        Try     'turns on error trapping
            'creates a streamreader object by opening text file for input
            sreStreamReader = IO.File.OpenText("smoke.txt")

            'process loop instructions until end of loop is encountered or _
            'no more text to read
            Do Until sreStreamReader.Peek = -1 _
                OrElse intNumber >= mitmMenuItems.Length

                'reads an items price and assign to array with info on 
separate _
                'lines in the file
                mitmMenuItems(intNumber).strItem = sreStreamReader.ReadLine()
                mitmMenuItems(intNumber).decPrice = _
                    Convert.ToDecimal(sreStreamReader.ReadLine())

                'adds item to list box
                Me.lstorder.Items.Add(mitmMenuItems(intNumber).strItem)

                'updates array
                intNumber = intNumber + 1

            Loop

            'closes file
            sreStreamReader.Close()

        Catch ex As Exception
            MessageBox.Show(ex.Message, "Smoke Shack BBQ", _
                MessageBoxButtons.OK, MessageBoxIcon.Information)
        End Try
    End Sub

    Private Sub btnexit_Click(ByVal sender As System.Object, ByVal e As 
System.EventArgs) Handles btnexit.Click
        'closes app
        Me.Close()

    End Sub

    Private Sub btnclear_Click(ByVal sender As System.Object, ByVal e As 
System.EventArgs) Handles btnclear.Click
        'clears controls
        Me.lblsub.Text = ""
        Me.lbltax.Text = ""
        Me.lbltotal.Text = ""
        Me.lstorder.ClearSelected()

    End Sub

    Private Sub btncalc_Click(ByVal sender As System.Object, ByVal e As 
System.EventArgs) Handles btncalc.Click
        'searches array for item selected in lstorder control
        'declares variables
        Dim strSearchFor As String
        Dim intNumber As Integer
        Dim decItemPrice, decTotal As Decimal

        'initialize variable
        strSearchFor = Convert.ToString(Me.lstorder.SelectedItem)

        'add 1 to array subscript until items are located in array
        Do Until mitmMenuItems(intNumber).strItem = strSearchFor
            intNumber = intNumber + 1

        Loop
How can I go about adding multiple selections and adding up all selections 
to get a total price?  Right now, I have changed the .SelectedItem to 
.SelectedItems and it says that my array is out of bounds.

Any help would be appreciated, 
Thanks,
Dave

2.data bound list boxes in visual basic .net

Hey all,

I have a windows form with a list boxes. I have data bound the list boxes
with data from my sql database. I want to use drag and drop to allow users
to choose different options from the list boxes on the form and drag them
into another empty list box that is not bound to any data when the form
loads. I was wondering is it possible to use drag and drop with data bound
list boxes ? If it is possible do you know of  any place on the net that
shows a good example ?

P.S. I can implement drag and drop when the list boxes are not data
binded...

Thanks in advance!

3.drag/drop with data bound list boxes in visual basic .net

Hey All,

I have been trying to implement drag and drop with data bound  list boxes . 
Does any one know if its possible?  I have been getting just the data row 
when ever I do the drag and drop or I have been getting the selected index 
number but I have not been getting the actually data item. I was thinking I 
might have to take the selected index number and use that to retrieve the 
actual data from the data set ?

Any help is much appreciated

Thank You,
Dwayne

4.Excel 2003 Visual Basic (List Box) in English not running in Germa

We developed an application in Excel 2003 with Visual Basic codes in English. 
 Our German prospective user has problem with the List Box.  The user is 
supposed to select chemical ions from the Selection box to the Selected Box.  
The ions could be selected or deselected to/from the list box.  Selected ions 
are then transposed to a Table on the Worksheet.  This is working in the 
English version.  However, the user seem to have problems in selecting & 
deselecting some of the ions.  Is there any special procedure without actual 
translation on our part for the English version to work properly in the 
german version.

The password input box is worikng.

Appreciate any help in this matter.

Thanks.

5.Excel 2003 Visual Basic (List Box) in English not running in G

Joel,,

It seems strange too.  Since I do not have a German version I can not really 
isolate the problem.  We run the program using a Japanese version and there 
was no error.  In fact my first thought was the interpretation of the 
subscript & superscript which I did not use in this case.

The VBs are a simple upload and selections for placement on another 
spreadsheet  where I do all the calculations.

One thought that came into mind is the Reference Library.  I used the Visual 
Basic for Application, MS Office Excel Object Library, Microsoft Forms.  I 
suppose if the version are different, that would cause a problem.

Thanks for your response.
