UID = Me.TextBox1.Text

Paw = Me.TextBox2.Text

If UID <> "" And Paw <> "" Then
If MainConfig.ExcuteLong("select * from UserID Where UserID = '" + UID + "' AND PASSWORD = '" + Paw + "'") >= 1 Then
Me.Close()

MessageBox.Show("密码不正确")
PASS = False
Return

这个是登录界面的代码，请教下如何在系统设置菜单中建立一个密码修改界面，求代码

[解决办法]
添加一个窗体，添加各种空间后，在设置菜单命令的代码中用form.showdialog来显示添加的那个窗体就行啦
[解决办法]
UPDATE UserID SET PASSWORD = '" & NEWPASSWORD & "' WHERE UserID = '" & USERID &"' AND PASSWORD = '" & OLDPASSWORD &"'"
