Problems - How to open a new window from a button ?

[eaa13]

Can someone help me by replying this msg about how to open a new window from a button in a form ?
I want to open a new form from the existing form i have created from the button of the existing form.
If I use the method of MDIForm, the form will be created inside the existing form.
I want the new form to be loaded not inside the existing form.
pls..... someone help me ?

Something like this.

Private Sub command1_click()
   'myNewForm is the form that you wish to show.
   myNewForm.Show
End Sub

Private Sub Command1_Click()

Dim newform As Object
Set newform = New Form1
newform.left = 400
newform.Top = 2000
newform.Visible = True


End Sub

Shouldn't you Dim it as a Form ??

[HeSaidJoe]

yes I suppose so, but object works as well..is there
a difference?

[Iain17]

Yep.

1. Dim an object as the correct type, in this case a form, and you will be able to see all of the correct properites and methods with VB's type ahead thingy.

2. If you dim a variable as an object, you get late binding. If you dim it as the correct type, you will get early binding, which is a lot quicker.

..thank you...
I'll adjust my notes......
I'll adjust my thoughts...

When dimensioning as Form versus Object, are not also allocating memory correctly from the start ? Therefore saving memory space and probably execution speed...

A little like declaring a variable as Double versus Variant. The compiler knows immediately how much memory to reserve.

Is that right ?

[Iain17]

No. Not with objects. You are right about variant versus othere types, but objects are diferent.

A Variable that is defined as an object is not actaully the object itself. It is just a 32 bit pointer to the object. As is a variable declared as a form. It is not the form, it is just a pointer to where the form is in memory.
