请教：下面的代码，把加密代码：password = MD5Encrypt("password") 放在什么 地方

Dim UserName As String = e.Form.Controls("UserName").Value
Dim dr As DataRow
If UserName = ""  Then
    Messagebox.show("请选择用户!","提示",MessageBoxButtons.OK,MessageBoxIcon.Information)
    Return
End If
dr = _UserTable.SQLFind("[Name] = \'" & UserName & "\'")
If dr Is Nothing Then
    Messagebox.show("此用户不存在!","提示",MessageBoxButtons.OK,MessageBoxIcon.Information)
    Return
End If
If e.Form.Controls("PassWord").Value = dr("Password") Then
    _UserName = UserName
    _UserGroup = dr("Group")
    e.Form.Close
Else
    Messagebox.show("密码错误!","提示",MessageBoxButtons.OK,MessageBoxIcon.Information)
End If

If e.Form.Controls("PassWord").Value = dr("Password") Then

改成

If dr("Password") = MD5Encrypt(e.Form.Controls("PassWord").Value) Then
