How to change the date format of a DateTimePicker in vb.net
提问by Failed_Noob
How can I change the date format of a DateTimePicker in vb.net so that the date is shown in the format dd/mm/1990, without any time value? I have tried changing the format to "short", and while this provides the date formatting I require it does not remove the time.
如何更改 vb.net 中 DateTimePicker 的日期格式，以便日期以 dd/mm/1990 格式显示，没有任何时间值？我尝试将格式更改为“短”，虽然这提供了我需要的日期格式，但它不会删除时间。

You need to set the Format of the DateTimePicker to Custom and then assign the CustomFormat.
您需要将DateTimePicker 的Format 设置为Custom，然后分配CustomFormat。
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
DateTimePicker1.Format = DateTimePickerFormat.Custom
DateTimePicker1.CustomFormat = "dd/MM/yyyy"
End Sub

Try this code it works:
试试这个代码它的工作原理：
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim CustomeDate As String = ("#" & DOE.Value.Date.ToString("d/MM/yyyy") & "#")
MsgBox(CustomeDate.ToString)
con.Open()
dadap = New System.Data.OleDb.OleDbDataAdapter("SELECT * FROM QRY_Tran where FORMAT(qry_tran.doe,'d/mm/yyyy') = " & CustomeDate & "", con)
ds = New System.Data.DataSet
dadap.Fill(ds)
Dgview.DataSource = ds.Tables(0)
con.Close()
Note : if u use ddfor date representation it will return nothing while selecting 1 to 9 so use dfor selection
注意：如果您dd用于日期表示，则在选择 1 到 9 时将不返回任何内容，因此d用于选择
'Date time format
'MMM Three-letter month.
'ddd Three-letter day of the week.
'd Day of the month.
'HH Two-digit hours on 24-hour scale.
'mm Two-digit minutes.
'yyyy Four-digit year.
The documentationcontains a full list of the date formats.
