说用户名是ADMIN
,密码是ADMIN
。它应该是自动登录并且它没有显示FORM 3. Visual Basic的代码是什么。我的正确吗?
我的表单输出:
这是我的示例代码:
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
If TextBox1.Text <> "" And TextBox2.Text <> "" Then
MsgBox("Invalid username and password, Please try again!", +vbExclamation, +vbOK)
ElseIf TextBox1.Text = My.Settings.Username And
TextBox2.Text = My.Settings.Password Then
MsgBox("Login Successfuly! Good day.", +vbInformation, +vbOK)
Form3.Show()
Me.Hide()
Else
MessageBox.Show("Please complete the required fields.", "Authentication Error" + TextBox1.Text + TextBox2.Text, MessageBoxButtons.OK, MessageBoxIcon.Error)
End If
End Sub
下面的代码是简单的登录表单按钮点击事件代码。
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If TextBox1.Text = "rfb" And TextBox2.Text = "reflection" Then
Form2.Show()
Else
MsgBox("Sorry, username or password not found", MsgBoxStyle.OkOnly, "Invalid")
End If
End Sub
根据您的需要更改代码。
您可以在代码中更改用户名和密码,其中用户名为“rfb”,密码为“reflection”。 - 查看更多:http://www.visual-basic-tutorials.com/form/LoginT.htm#sthash.yb1ihiFB.dpuf
