[RESOLVED] Form Minimum Size

I'm trying to limit the size of the form. Basically, i have a form which i don't want to be smaller than 5000 by 3000 twips. So the basic thing which you can think of in a millisecond is this:

Code:

---

Private Sub Form_Resize()
  If Me.Width < 5000 Then Me.Width = 5000
  If Me.Height < 3000 Then Me.Height = 3000
End Sub

---

But if you try that it looks REALLY nasty when you go smaller as it flashes like crazy. How can i accomplish the same thing except doing it much cleaner like lots and lots of other programs which have a minimum size?

Normally I don't have a lot of use for PSC, but here is an article that lays out the issues and your options from simple to complex fairly well:

The easiest uses a Timer control to assist with resizing.

Here is a boiled down and cleaned up example of his approach you can test quickly by creating a new project with one Form and adding one Timer to it:

Code:

---

Option Explicit
'Relies on a Timer named tmrResizeHelp.

Private Const FORM_MINWIDTH = 3600
Private Const FORM_MINHEIGHT = 3300

Private Declare Function GetKeyState Lib "user32" ( _
    ByVal nVirtKey As KeyCodeConstants) As Integer

Private Sub Form_Load()
 With tmrResizeHelp
    .Enabled = False
    .Interval = 100
 End With
End Sub

Private Sub Form_Resize()
    If WindowState <> vbMinimized Then
        'Min size control logic:
        If Width < FORM_MINWIDTH Or Height < FORM_MINHEIGHT Then
            Refresh
            tmrResizeHelp.Enabled = True
            Exit Sub
        End If
        'Your control resizing and moving goes here:
        '...
    End If
End Sub

Private Sub tmrResizeHelp_Timer()
    If GetKeyState(vbKeyLButton) < 0 Then Exit Sub
    tmrResizeHelp.Enabled = False
    If WindowState = vbMinimized Then Exit Sub
    If Width < FORM_MINWIDTH Then Width = FORM_MINWIDTH
    If Height < FORM_MINHEIGHT Then Height = FORM_MINHEIGHT
End Sub

---

Test it to be sure the results are something that works for you.

Thanks for the reply. That works pretty well with a timer, maybe i'll do that. I went to the website and kinda got lost in the more complicated code... Anyway, there really is no way of making it completely stop when it's too small? While toying around with VB2010 i noticed that minimum form size was a property so i was hoping that the same could be done with apis or something. The timer thing will do though so my question has been answered. Thanks a lot for your help!
