Hello i'm making a login program, and I made a error display box which works but it just suddenly stopped working and idk why, it just doesn't work anymore when you fill out the password box but not the username box ..

Any idea's why?

Public Class Form1

    Private User As String
    Private Pass As String

    Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        If Not TextBox1.Text = "" Then
            User = TextBox1.Text
            Label4.Text = ""
        Else
            Label4.Text = "Please input a username!"
        End If
        If Not TextBox2.Text = "" Then
            Pass = TextBox2.Text
            Label4.Text = ""
        Else
            If Not Label4.Text = "Please input a username!" Then
                Label4.Text = "Please input a password!"
            Else
                Label4.Text = "Please input a username, password!"
            End If
        End If
    End Sub
End Class

I dont see any code that shows an error display box. you could use

if password ="" or name ="" then
messagebox.show("Pleese fill out completly")

or

do while name="" or password=""
messgebox.show("pleese fill out")
loop

or somthing like that.

    Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        If Not TextBox1.Text = "" Then
            User = TextBox1.Text
            Label4.Text = ""
        Else
            Label4.Text = "Please input a username!"
        End If
        If Not TextBox2.Text = "" Then
            Pass = TextBox2.Text
        Else
            If Not Label4.Text = "Please input a username!" Then
                Label4.Text = "Please input a password!"
            Else
                Label4.Text = "Please input a username, password!"
            End If
        End If
    End Sub
End Class

Try that. when you cleared label4 in the second if statement, it made the username check pointless as the label was empty
