Overflow when minimizing!

There are times when I have a Form floating above another form (vbmodeless).  The floating form does not have minimize/maximize/close enabled... (it's borderstyle is 0 / none).

When I attempt to minimize my application and keep the floating form visible, I get an overflow ('6') error.  Is there a way around this?

Please show your main (minimized) form_Resize event code

it's not the resize code that is the error... it's the Form_Activate code that is probably the culprit.  There are a number of fixed size forms in the application... when Form1 is closed and Form2 is shown, I want it to appear in the same screen co-ordinates.  So I save the current coordinates into 2 variables.. (SetTop & SetLeft) ... which are then called on FormLoad / FormActivate.

Form Activate()
    Me.Top = SetTop
    Me.Left = SetLeft
End Sub

Check form state:
Form Activate()
 If Me.WindowState = vbNormal Then
    Me.Top = SetTop
    Me.Left = SetLeft
 End If
End Sub

But i think the problem is that SetTop or SetLeft have illegal data.
Form's property Top defined As Single, are you sure that SetTop returns Single?

if windowstate=vbnormal on
Form Activate

and on Form Deactivate (Where it sets SetTop and SetLeft)

works fine... thank you!

This error occured since vbMinimized form can not resize (while vbMaximized can). IMHO, better solution is:
If Me.WindowState = vbMinimized Then Exit Sub
