Ⅰ 跪求VB.net的小作品源代碼,要完整的
不管什麼代碼都可以嗎?我倒是有一個小的不能再小的代碼,是把窗體上的內容生成一個word文檔
Ⅱ 用vb.net編寫記事本源代碼

Text1.SetFocus '文本框獲得焦點,以顯示所找到的內容Search = InputBox("請輸入要查找的字詞:")
Where1 = InStr(Text1.Text, Search) '在文本中查找字元串
If Where1 Then
'若找到則設置選定的起始位置並使找到的字元串高亮
Text1.SelStart = Where1 - 1
Text1.SelLength = Len(Search)
' Me.Caption = Where1 '測試用
'否則給出提示
Else: MsgBox "未找到所要查找的字元串。", vbInformation, "提示"
End If
End Sub

Ⅲ vb.net排課程序源碼,必有高分報答。
Dim cnstr As String = "連接字串"
Using cnn As New SqlClient.SqlConnection(cnstr)
cnn.Open()
Using da As New SqlClient.SqlDataAdapter("select * from tb where id <@id order by id", cnn), tb As New DataTable
' @id是查詢傳遞的參數。order BY ID 就是排序了。
da.SelectCommand.Parameters.Add("@id", SqlDbType.Int).Value = 10
da.Fill(tb)
'以下為顯示數據
Dim dgv As New DataGridView
dgv.DataSource = tb
dgv.Dock = DockStyle.Fill
Me.Controls.Add(dgv)
End Using
End Using
Ⅳ 求vb.net的源代碼,最好說明其解決問題,越多越好,滿意加50分。
下面這段代碼,是我用來計算每個月存500元進銀行,連續30年,最後連本帶利能有多少錢。這裡面涉及復利計算。界面中右邊的文本框用來輸出每一次計算的結果。
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim nianxian As Integer '年限變數
Dim dingcun As Integer '定存變數
Dim fuli_big As Long '大復利
Dim fuli_small As Long '小復利
Dim i As Integer '循環變數
Dim DATAstring As String '數據字元串
nianxian = Val(年限_TextBox.Text)
dingcun = Val(定存_TextBox.Text)
DATAstring = ""
For i = 1 To nianxian
fuli_small = dingcun * (1 + 0.1875)
dingcun = fuli_small
fuli_big = fuli_big + fuli_small
DATAstring = DATAstring + "[" + Trim(Str(i)) + "]" + Str(fuli_big) + Chr(13) + Chr(10)
'DATAstring = DATAstring + "[" + Trim(Str(i)) + "]" + Str(fuli_small) + Chr(13) + Chr(10)
Next
'fuli_big = fuli_small
TextBox1.Text = DATAstring
結果_TextBox.Text = Str(fuli_big) + "元"
End Sub

Ⅵ 如何用vb.net獲得網頁的源代碼
Dim url As String=" 網址"
Dim httpReq As System.Net.HttpWebRequest
Dim httpResp As System.Net.HttpWebResponse
Dim httpURL As New System.Uri(url)
httpReq = CType(WebRequest.Create(httpURL), HttpWebRequest)
httpReq.Method = "GET"
httpResp = CType(httpReq.GetResponse(), HttpWebResponse)
httpReq.KeepAlive = False ' 獲取或設置一個值,該值指示是否與
Internet資源建立持久連接。
Dim reader As StreamReader = _
New StreamReader(httpResp.GetResponseStream,
System.Text.Encoding.GetEncoding(-0))
Dim respHTML As String = reader.ReadToEnd() 'respHTML就是網頁源代碼
