我有一個excel工作表,其中包含我想用datetimepicker(僅需要日期)的日期。我只想點擊datetimepicker,選擇一個日期,並且它必須向我顯示數據網格視圖中的信息。這是我的按鈕代碼。如何讓datetimepicker工作
我有一個txt框,我已經嘗試過,但無法獲得日期,我現在把一個datetimepicker框,但無法讓ii工作。
對此有幫助。
這裏是我的主要代碼
Imports System.Data.OleDb
Public Class Tapes_info
Private dtGlobal As New DataTable
Private Sub Tapes_info_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
dtGlobal.Clear()
Using cn As New OleDb.OleDbConnection
Dim Builder As New OleDbConnectionStringBuilder With {.DataSource = IO.Path.Combine(Application.StartupPath, "Backuptapes.xls"), .Provider = "Microsoft.ACE.OLEDB.12.0"}
Builder.Add("Extended Properties", "Excel 12.0; IMEX=1;HDR=No;")
cn.ConnectionString = Builder.ConnectionString
cn.Open()
Using cmd As OleDbCommand = New OleDbCommand With {.Connection = cn}
cmd.CommandText = "SELECT TOP 5130 F1 As Tapes, F2 As Containere, F3 as ContainerRef, F4 as DateOut FROM [Tapese$]"
Dim dr As System.Data.IDataReader = cmd.ExecuteReader
dtGlobal.Load(dr)
LstTape.DisplayMember = "Tapes"
LstTape.DataSource = dtGlobal
txtContainer.DataBindings.Add("Text", dtGlobal, "Containere")
txtContainerRef.DataBindings.Add("Text", dtGlobal, "ContainerRef")
txtDateOut.DataBindings.Add("Text", dtGlobal, "Dateout")
End Using
End Using
End Sub
這裏是我的按鈕的代碼,我要顯示我想要的任何日期。
Private Sub BtnSearchDateOut_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnSearchDateOut.Click
For i As Integer = 0 To dtGlobal.Rows.Count - 1
If IsDBNull(dtGlobal.Rows(i)("Dateout")) Then
dtGlobal.Rows(i)("Dateout") = ""
End If
Next
Dim query = From item In dtGlobal.AsEnumerable() Where item.Field(Of String)("Dateout").StartsWith(txtSearchDateOut.Text) Select item
If query.Count > 0 Then
Dim newDT As DataTable = query.CopyToDataTable()
MsgBox(newDT.Rows.Count.ToString() & " Date out found.")
Dim frm As New Form()
Dim dgv As New DataGridView()
dgv.DataSource = newDT
dgv.Refresh()
frm.Controls.Add(dgv)
dgv.Dock = DockStyle.Fill
frm.Size = New Size(1400, 700)
frm.Show()
Else
MsgBox("There is no Date for this found.") 'message
End If
哪種語言? –
我正在使用的程序是vb.net 2010 – Hendrik
那麼你應該標記有問題的語言。讓我爲你做。否則你將無法得到答案 –
