Click event in an If to check if already clicked...

[AwesomeNexus]

Hello,

I have a custom maximize box made for my application. I want it to be so that when I click it once then it maximizes, but if I click it again, it returns to the previous size. My code:

    Private Sub PictureBox3_Click(sender As Object, e As EventArgs) Handles PictureBox3.Click
        Me.WindowState = FormWindowState.Maximized
        If WindowState = FormWindowState.Maximized Then
            If PictureBox3.click() Then Close()
        End If
    End Sub

Error: is an event handler and cannot be called directly, use "raiseevent" instead.

Ok, i put if event and it seems ok but says expression expected. WTH?

I don't think you can do:

If PictureBox3.click() then Close

First off PictureBox3.click is a method and it does not return a boolean.
Second - calling Picturebox3.click inside PictureBox3_click (which handles Picutebox3.click) is recursive and bound to just get you into trouble...
Instead try...

Private Sub PictureBox3_Click(sender As Object, e As EventArgs) Handles PictureBox3.Click
        Static bClicked as Boolean = False
        if bClicked = False then
            bClicked = True
            Me.WindowState = FormWindowState.Maximized
        End if
    End Sub
 

Of course you have no way to then minimize or normalize the form. Instead I would recommend you set it up as a toggle...

Private Sub PictureBox3_Click(sender As Object, e As EventArgs) Handles PictureBox3.Click
        If Me.WindowState = FormWindowState.Maximized Then
            Me.WindowState = FormWindowState.Normal
        Else
            Me.WindowState = FormWindowState.Maximized
        End If
End Sub
 

This sets up a nice toggle between normal and maximized.
