Question

我遇到的问题是，当我在vb.net中开发我的应用程序的安装文件时，数据库文件将不会附加到它，作为一个解决方案，我希望创建数据库@首次运行应用程序通过以下代码

Dim myCommand As String
Dim myConnectionString As SqlConnection = New SqlConnection("Data Source=(local)\SQLEXPRESS;Initial Catalog=soft_billing;Integrated Security=True;Pooling=False")
        myCommand = "CREATE database soft_billing"
        Dim cmd As SqlCommand = New SqlCommand(myCommand, myConnectionString)
        Try
           cmd.Connection.Open()
           cmd.ExecuteNonQuery()
           cmd.Connection.Close()
        Catch
            MsgBox(" Already installed database", MsgBoxStyle.Critical, " MaS InfoTech- Warning")

        End Try

它不会生成所需的数据库，请帮助我，谢谢你的推荐
