International dayNames

International dayNames

Cool example although, it would have been a good idea to include comments in your code so users could know how to use the code and what it happening.

here it is with comments. HTH:

vb Code:

Imports System.Globalization
 
Public Class Form1
 
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    'create new datatable
    Dim dt As New DataTable
    'add 7 columns for dayNames() (0 to 6 = sunday to saturday)
    dt.Columns.Add("0")
    dt.Columns.Add("1")
    dt.Columns.Add("2")
    dt.Columns.Add("3")
    dt.Columns.Add("4")
    dt.Columns.Add("5")
    dt.Columns.Add("6")
    'add a column for the EnglishName of the culture
    dt.Columns.Add("cultureName")
 
    'for each individual culture
    For Each ci As CultureInfo In CultureInfo.GetCultures(CultureTypes.SpecificCultures)
        'create a new list + add DayNames() + EnglishName
        Dim fields As New List(Of String)(New CultureInfo(ci.Name).DateTimeFormat.DayNames)
        fields.Add(ci.Parent.EnglishName)
        'add a new row to the datatable containing the contents of the fields list
        Dim dr As DataRow = dt.NewRow
        dr.ItemArray = fields.ToArray
        dt.Rows.Add(dr)
    Next
 
    'select distinct rows from the datatable
    dt = dt.DefaultView.ToTable(True, New String() {"cultureName", "0", "1", "2", "3", "4", "5", "6"})
    'remove unwanted rows from the datatable
    For x As Integer = dt.Rows.Count - 1 To 0 Step -1
        If dt.Rows(x).Item("cultureName").ToString = "Invariant Language (Invariant Country)" Then
            dt.Rows.Remove(dt.Rows(x))
        End If
    Next
 
    'setup the databindings
    ComboBox1.DisplayMember = "cultureName"
    ComboBox1.DataSource = dt
 
    TextBox1.DataBindings.Add("Text", dt, "0") 'sunday
    TextBox2.DataBindings.Add("Text", dt, "1") 'monday
    TextBox3.DataBindings.Add("Text", dt, "2") 'tuesday
    TextBox4.DataBindings.Add("Text", dt, "3") 'wednesday
    TextBox5.DataBindings.Add("Text", dt, "4") 'thursday
    TextBox6.DataBindings.Add("Text", dt, "5") 'friday
    TextBox7.DataBindings.Add("Text", dt, "6") 'saturday
 
End Sub

hi .paul, i hope that your program run flawlessly, i haven't checked yet. Actually i am not understanding the code instead of your comments. now what i do?

The only relevant bit is the CultureInfo.DateTimeFormat.DayNames property (line 22), which returns a string array with the names of the days in the language corresponding to that culture. Besides that, there is a loop through all cultures (line 20). The rest is just databinding to get the days into the textboxes.

By the way paul, thanks for this. I didn't know this information was available this easily. I'm using it for a month calendar control I'm creating, so now I can make it culture specific. The DateTimeFormat also specifies other things such as month names, abbreviated day and month names, first day of the week, etc. All very useful for a calendar control :)
