Public variable

Hi Experts,

How to create a public variable which can be used only in the form. Suppose I have form1.aspx. How can I define a public variable which can be used only in form1 .no other form should able to access it.

Just declare it in the class module of Form1, and mark it Private:

Private MyVariable As Integer

Thank you for your reply. When it is private is it shared by only one instance or multiple instance? I think it for one instance only, just want to conform.

A private variable is not shared at all. If you are wanting to *Share* a variable (in VB terms and .NET definitions), then you would mark it as Shared. Methods, Properties and Fields defined within Modules are inherently Shared.

That being said, if you instantiate a form (which is a Class object); e.g. -

Dim frm As New Form1

Open in new window

Then the object that instantiated frm has access to frm. If frm, by definition of Form1, contains a public field/property called someRandomThing, then the object that instantiated frm has access to this field/property.

Hi,

When I declare as "Private MyVariable As Integer" still I can not access it in all the sub of that class. But When I declared as
"Private Shared MyVariable As Integer" then I can access it from all the subs. Is that the right way?

Thanks.
