Basically what the title says
I have several Buttons which redirect me to a 2nd form using me.Hide and Form2.show
However, what I would like is that when Button1 is clicked, x=1 in the recently opened form. When Button2 is clicked -> x=2, etc.
Does anyone know how to do this?
An alternative method is to pass a variable into the constructor of a form, such as:
Public Class Form2
Dim_value As Integer
Public Sub New(ByVal value As Integer)
_value = value
End Sub
End Class
Which you would call like this:
Dim f As New Form2(12345)
f.Show()
You can then use _value
(or whatever you want to call it) throughout Form2.
The difference here is this is that your value cannot be changed by any other form once Form2 is instantiated; this may be an advantage or disadvantage depending on your requirements but it does keep things nicely separated and easier to maintain. You could also make _value
a read-only property which will let others forms read the value but not set (change) it.
There are several ways you can do this, but for the sake of simplicity I suggest that you define and use a public method in Form2. Here's a small example which you can use for inspiration:
Public Class Form2
Private variableX As Integer = 0
Public Sub SetVariableX(value As Integer)
variableX = value
End Sub
End Class
and when you reveal Form2:
Form2.show
Form2.SetVariableX(9999)
Have fun.
