vb.netqq源码 vb winsock 源码

vb.net中,在sql server2000数据库中插入图片，最好有源码，有懂的朋友可以家我QQ1971951508

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

ExeDMLSQL()

End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

Dim strsql As String = "select * from 产品图片 where 序号=1"

Dim objcommand As New SqlCommand(strsql, New SqlConnection(connection))

objcommand.Connection.Open()

Dim myreader As SqlDataReader = objcommand.ExecuteReader()

If myreader.Read() Then

Dim imgInfo() As Byte = myreader("图片")

Dim memoryStream As New MemoryStream(imgInfo)

PictureBox1.Image = Image.FromStream(memoryStream)

End If

End Sub

Private Sub ExeDMLSQL()

Dim st As New FileStream("D:\1.png", FileMode.Open, FileAccess.Read)

Dim mbr As New BinaryReader(st)

Dim buffer(st.Length) As Byte

mbr.Read(buffer, 0, CInt(st.Length))

st.Close()

InsertImage(buffer)

End Sub

Private Sub InsertImage(ByVal buffer() As Byte)

Dim cn As New SqlConnection(connection)

cn.Open()

Dim cmd As New SqlCommand("SaveImg", cn)

cmd.CommandType = CommandType.StoredProcedure

cmd.Parameters.Add("@name", SqlDbType.VarChar).Value = 1

cmd.Parameters.Add("@image", SqlDbType.Image).Value = buffer

cmd.ExecuteNonQuery()

MsgBox("Image inserted.")

cn.Close()

End Sub

SaveImg是一个存储过程:

ALTER PROCEDURE dbo.SaveImg

@name AS int,

@image AS IMAGE

AS

INSERT INTO 产品图片 (序号, 图片)

VALUES (@name, @image)

相关问答

Q1: VB源码：QQ自动登陆器，关于输入QQ号码位数的修改

If Len(txtQQNumber.Text) 9 Then KeyAscii = 0: 这行才是控制输入位数vb.netqq源码的

Q2: 求vb.net的源代码，最好说明其解决问题，越多越好，满意加50分。

下面这段代码vb.netqq源码，是vb.netqq源码我用来计算每个月存500元进银行，连续30年，最后连本带利能有多少钱。这里面涉及复利计算。界面中右边vb.netqq源码的文本框用来输出每一次计算vb.netqq源码的结果。

  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

      Dim nianxian As Integer '年限变量

      Dim dingcun As Integer '定存变量

      Dim fuli_big As Long '大复利

      Dim fuli_small As Long '小复利

      Dim i As Integer '循环变量

      Dim DATAstring As String '数据字符串

      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

      结果_TextBox.Text = Str(fuli_big) + "元"

  End Sub

Q3: 写一个vb.net代码，关于登陆和关闭Q~程序，窗口如下已经设计好。

vb.netqq源码你设计一个界面vb.netqq源码，让别人来写代码，可能吗vb.netqq源码？

另外根据你的想法，VB.NET没法实现，需要用C++写DLL注入，还要破解QQ的加密函数！
