刚听了SMART CLIENT部署的讲座,里面详细讲述了如果在.NET安装工程里运行自定义的DLL或者EXE,以后在自定义的工程中如何得到安装工程的传递过来的参数。下面大致说一下自己的心得：
首先，是制作一个类工程。然后添加一个安装类文件，并添加一个SQL.TXT文件,当作嵌入的资源,类的代码如下,在后面再做说明:
Dim Cn As SqlConnection
'得到SQL脚本字符串
Private Function GetSql(ByVal Name As String) As String
Try
'通过反射取到程序集
Dim Asm As [Assembly] = [Assembly].GetExecutingAssembly()
'读取资源文件资料,要将资源文件在编译时设成嵌入的资源
Dim Sm As Stream = Asm.GetManifestResourceStream(Asm.GetName().Name + "." + Name)
Dim Rr As New StreamReader(Sm)
Return Rr.ReadToEnd
Catch ex As Exception
MsgBox(Err.Description, MsgBoxStyle.OKOnly, "出错提示")
Throw ex
End Try
End Function
'得到数据库备份文件路径
Private Function GetBakFilePath(ByVal DatFileName As String) As String
Try
'通过反射取到程序集
Dim Asm As [Assembly] = [Assembly].GetExecutingAssembly()
'读取资源文件资料,要将资源文件在编译时设成嵌入的资源
Dim Sm As Stream = Asm.GetManifestResourceStream(Asm.GetName().Name + "." + DatFileName)
If File.Exists("c:\" & DatFileName) Then
File.Delete("c:\" & DatFileName)
End If
Dim Fs As New FileStream("c:\" & DatFileName, FileMode.Create)
Dim Sw As New BinaryWriter(Fs)
Dim recbyte(Sm.Length - 1) As Byte
Dim strread As New BinaryReader(Sm)
strread.Read(recbyte, 0, recbyte.Length)
Sw.Write(recbyte, 0, recbyte.Length)
Sw.Close()
Fs.Close()
Return "C:\" & DatFileName
Catch ex As Exception
MsgBox(Err.Description, MsgBoxStyle.OKOnly, "出错提示")
Throw ex
End Try
End Function
Private Sub ExecuteSql(ByVal DbName As String, ByVal SqlText As String, ByVal uid As String, ByVal pwd As String, ByVal servername As String)
Dim cmd As New SqlCommand(SqlText, Cn)
If Cn.State = ConnectionState.Closed Then Cn.Open()
Try
Cn.ChangeDatabase(DbName)
cmd.ExecuteNonQuery()
Catch ex As Exception
MsgBox("运行SQL脚本出错!", MsgBoxStyle.OKOnly, "提示")
Throw ex
End Try
Cn.Close()
End Sub
Protected Sub AddDBTable(ByVal DBName As String, ByVal uid As String, ByVal pwd As String, ByVal servername As String)
'判断数据库是否存在
Try
Cn = New SqlConnection("Persist Security Info=False;User ID=" & uid & ";Initial Catalog=master;Data Source=" & servername & ";password=" & pwd & ";Max Pool Size=75000")
Dim Dt As New DataTable()
Cn.Open()
Dim cmd As New SqlDataAdapter()
cmd.SelectCommand = New SqlCommand("exec sp_helpdb", Cn)
cmd.Fill(Dt)
Dim i As Int16
For i = 0 To Dt.Rows.Count - 1
If DBName.ToLower = CType(Dt.Rows(i).Item(0), String).ToLower Then
'数据库存在
cmd = Nothing
Cn.Close()
Exit Sub
End If
Next
Catch ex As Exception
MsgBox(Err.Description & "连接数据库出错,请检查所输入的参数是否正确!", MsgBoxStyle.OKOnly, "出错提示")
Exit Sub '如已存在则跳出
End Try

Try
'========方法一:运行SQL脚本创建数据库
' ExecuteSql("Master", "Create DataBase " & DBName, uid, pwd, servername)
'ExecuteSql(DBName, GetSql("mySql.txt"), uid, pwd, servername)
'==
