vb.net2008教程 vb2010教程

急高手幫忙教下怎么用VB.NET2008做個(gè)查詢學(xué)生課程信息的資料庫啊???

我用vb做了一個(gè)程序?qū)?shù)據(jù)庫中的數(shù)據(jù)進(jìn)行排序,程序如下:

我們提供的服務(wù)有:做網(wǎng)站、成都做網(wǎng)站、微信公眾號(hào)開發(fā)、網(wǎng)站優(yōu)化、網(wǎng)站認(rèn)證、貢覺ssl等。為1000多家企事業(yè)單位解決了網(wǎng)站和推廣的問題。提供周到的售前咨詢和貼心的售后服務(wù),是有科學(xué)管理、有技術(shù)的貢覺網(wǎng)站制作公司

標(biāo)準(zhǔn)模塊:

Type nas

custno As Integer

last_name As String

first_name As String

vip_status As String

address1 As String

assress2 As String

city As String

state As String

post_code As String

country As String

phone As String

fax As String

email As String

remarks As String

End Type

窗體模塊:

Option Base 1

Dim aa(30) As nas

Dim t As nas

Private Sub Command1_Click()

Open "e:\vbb\custoly.db" For Random As #1

For i = 1 To 30

Get #1, i, aa(i)

i = i + 1

Next i

For j = 1 To 29

For k = j + 1 To 30

If aa(j).last_name aa(k).last_name Then

t = aa(j)

aa(j) = aa(k)

aa(k) = t

End If

Next k

Next j

For p = 1 To 30

print aa(p).last_name

Next p

End Sub

vb.net 2008 怎樣進(jìn)入調(diào)試模式?怎樣逐語句運(yùn)行?怎樣添加監(jiān)視?

在VB環(huán)境中執(zhí)行源代碼,本身就是調(diào)試模式

按F8即可逐語句運(yùn)行

點(diǎn)擊語句左端空白處,將其背景色變?yōu)樯罴t,就是添加斷點(diǎn),運(yùn)行到該語句會(huì)停下來

可以在變量、對(duì)象等語句上點(diǎn)擊右鍵,選擇“添加監(jiān)視”即可

怎樣用vb.net2008讀寫注冊(cè)表?

(1)添加項(xiàng)

Dim reg As RegistryKey

reg = Registry.CurrentUser

reg = reg.OpenSubKey("Software\Microsoft\Internet Explorer\Main", True)

reg.SetValue("Window Title", Me.TextBox1.Text)

(2)讀取項(xiàng)

Dim reg As RegistryKey

Dim regStr As String

reg = Registry.CurrentUser

reg = reg.OpenSubKey("Software\Microsoft\Internet Explorer\Main", True)

regStr = reg.GetValue("Window Title")

Me.TextBox1.Text = regStr

(3)刪除項(xiàng)

Dim reg As RegistryKey

reg = Registry.CurrentUser

reg = reg.OpenSubKey("Software\Microsoft\Internet Explorer\Main", True)

reg.DeleteValue("Window Title")

VB.net 2008如何寫用戶控件?

參考:

Public Class UserControl1

#Region "變量"

Dim Down_Color As Color = Color.Blue

Dim UP_Color As Color = Color.Gray

Dim Mode As Short = 0

Dim flag As Boolean

Dim offset_X As Integer

Dim offset_Y As Integer

Dim Mouse_P As Point

#End Region

#Region "屬性"

'按下顏色

Public Property _DownColor As Color

Get

Return Down_Color

End Get

Set(ByVal value As Color)

Down_Color = value

End Set

End Property

'彈起顏色

Public Property _UpColor As Color

Get

Return UP_Color

End Get

Set(ByVal value As Color)

UP_Color = value

End Set

End Property

'滑動(dòng)模式 0-橫 1-豎

Public Property _Mode As Short

Get

Return Mode

End Get

Set(ByVal value As Short)

Mode = value

End Set

End Property

#End Region

Private Sub UserControl1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Me.BackColor = UP_Color

End Sub

'鼠標(biāo)按下

Private Sub UserControl1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown

Me.BackColor = Down_Color

Mouse_P = e.Location

flag = True

End Sub

'鼠標(biāo)移動(dòng)

Private Sub UserControl1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove

If flag = False Then Exit Sub

Select Case Mode

Case 0 '橫向·

offset_X = e.X - Mouse_P.X

If Me.Location.X + offset_X + Me.Width = Me.ParentForm.Width Or Me.Location.X + offset_X = 0 Then

flag = False

Else

Me.Location = New Point(Me.Location.X + offset_X, Me.Location.Y)

End If

Case 1 '豎向·

offset_Y = e.Y - Mouse_P.Y

If Me.Location.Y + offset_Y + Me.Height + 30 = Me.ParentForm.Height Or Me.Location.Y + offset_Y = 0 Then

flag = False

Else

Me.Location = New Point(Me.Location.X, Me.Location.Y + offset_Y)

End If

End Select

End Sub

'鼠標(biāo)彈起

Private Sub UserControl1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseUp

Me.BackColor = UP_Color

flag = False

End Sub

End Class

vb.net2008如何操作FTP服務(wù)器?比如登錄并保持登錄狀態(tài),然后遍歷根目錄及指定的目錄,以獲

具體方法如下:”、打開Serv-U的配置管理界面puzb在“全局用戶”或者“域用戶”中選擇“創(chuàng)建cgko修改和刪除用戶帳戶”; 2、在“創(chuàng)建,修改和刪除用戶帳戶”的界面,選擇“添加”。;3、在“用戶屬性“對(duì)話框,“用戶信息”下的用戶名為:Anonymous,密碼為空,為其指定FTP的根目錄?!?、然后在“目錄訪問“選項(xiàng),點(diǎn)擊“添加”,為其指定訪問權(quán)限和目錄?!?、最后點(diǎn)擊“保存”6這樣我們就成功添加了匿名用戶。
