Raise Event and OnClick

I have a button that I need to use twice, the first time I click it, it validates that a string inside a textbox is a certain length. That part works. What I want to do is press the same button again but when I press it the second time it is suppose to popup a hidden label. But when I try to use a raiseevent command it gives me an error saying "the button is not an event in my program" can any tell me what I am doing wrong.

Or tell me how to use the OnClick

If you do that you'll end up with a non-standard UI which will confuse your users.
However, if you just really want to do that a simple way would be to use a static boolean variable in the click event that is already provided.
Each time the event is raised you can respond as per the value of the boolean.
Simply continually change the boolean from true to false to true...each time the button is clicked and then do as you please with the code.

try this:

vb Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Static clicks As Integer = 1
    If clicks = 1 Then
        'check your textbox
        clicks += 1
    Else
        Label1.Visible = True 'or however you're revealing your hidden label
    End If
End Sub

edit: or use a boolean as fourblades suggested

Ok how would I go about doing this

It is a program I am trying to write I have two button a submit button and a reset button. I enter a string into a textbox and press the submit button and if the string isn't the right lenght I get an error an a message box. After I press ok in the message box to get it off the screen I should press the reset button to clear the textbox. But if i don't press the reset button and press the submit button instead thats when the label is suppose to popup saying "please press the reset button".

Well then ignore my previous post.
What you want is different than what I thought.

Ok thanks I have figures out the rest of the program this is the only part that is giving me trouble I guess I will have to try to keep searching

Code:

---

Public Class frm_project
      Dim WarningLabel As Boolean = False

---

then inside your private sub button, check for the boolean value before any other part of your statement. Then check the uservalue

Code:

---

        If WarningLabel = True Then
                    lbl_ClearWarn.Visible = True     
                ElseIf uservalue.Length <> 12 Then
                    WarningLabel = True
                    MessageBox.Show("bla bla bla")

---

then set your Reset button to put the Boolean back to False, as well as your Label.Visible to False

Code:

---

        WarningLabel = False
        txt_UserWords.Text = "Reset Button"
        'Clear the Red/Blue Warning Box
        If lbl_ClearWarn.Visible = True Then
            lbl_ClearWarn.Visible = False
        End If

---

I think this will work:

Code:

---

Public Class Form1

    Private MessageboxAlreadyShown As Boolean

    Private Sub Form1_Shown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shown
        Me.Label1.Visible = False
    End Sub

    Private Sub ButtonSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonSubmit.Click

        If Not Me.TextBox1.Text.Length = 20 Then
            Select Case True
                Case MessageboxAlreadyShown = True
                    Me.Label1.Visible = True
                Case MessageboxAlreadyShown = False
                    MessageBox.Show("Error Message")
                    MessageboxAlreadyShown = True
            End Select
        Else
            'continue processing
            MessageboxAlreadyShown = False
        End If
    End Sub

    Private Sub ButtonReset_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonReset.Click
        Me.TextBox1.Text = String.Empty
        Me.Label1.Visible = False
        MessageboxAlreadyShown = False
    End Sub


End Class

Ooops minor problem. This will work as a user would expect:

Code:

---

Public Class Form1

    Private MessageboxAlreadyShown As Boolean

    Private Sub Form1_Shown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shown
        Me.Label1.Visible = False
    End Sub

    Private Sub ButtonSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonSubmit.Click

        If Not Me.TextBox1.Text.Length = 20 Then
            Select Case True
                Case MessageboxAlreadyShown = True
                    Me.Label1.Visible = True
                Case MessageboxAlreadyShown = False
                    MessageBox.Show("Error Message")
                    MessageboxAlreadyShown = True
            End Select
        Else
            Me.Label1.Visible = False
            'continue processing
        End If
    End Sub

    Private Sub ButtonReset_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonReset.Click
        Me.TextBox1.Text = String.Empty
        Me.Label1.Visible = False
        MessageboxAlreadyShown = False
    End Sub


End Class
