Variable/String assignment

How can I save/assign a string so that I can recall it in different windows? Dim doesn't work and I can't find anything else. Thanks

Second part of thread split into its own thread here

Dim does what it does and nothing else. Dim declares a variable. Passing data to a form is just like passing data to any other object. You would generally need the data assigned to a variable first, and that variable would need to be declared with the Dim key word.

There's a link in my signature that provides information on passing data between forms.

And therefore there's absolutely no reason to post it in this thread. One thread per topic and one topic per thread please. In future please take the extra 10 seconds required to create a new thread for a new question.

Use Public in place of Dim.

For instance, use Public MyString As String

And if that was called in Form1, you'd refer to it in other forms as Form1.MyString.

Beaten to it... :P

thanks but i get an error saying that public is not valid on a local variable declaration

In a procedure you can only use Dim or Static to declare a variable. If you're wanting to 'save' it's value then you would have to declare it at the class level.

vb.net Code:

Public Class Form1
'Declare here
Public s As String
 
   Public Sub SomeMethod()
 
    End Sub
 
 
End Class

Edit: here's a link to Access Modifiers since they tie together.

ok thanks, but is there a command like that which i can enter into a private sub?

EDIT: The error i keep getting is: '...' is not valid on local variable declaration. so what i'm looking for is a valid local variable declaration besides Dim which I can use/recall in multiple forms

you can't ... it's a LOCAL variable... if you need to use it outside the sub, then it needs to be declared out side the sub.... further, if it is needed outside the form,, then you need to use Public so that it can be used outside the form....

i tried that but it doesnt work for what i want to do. i want to make it so that when the user presses a button it saves whatever is in textbox1.text to a variable or string which can be recalled in another form. but i cant do what youre proposing for an action of a button

Did you read the link I gave you?

vb.net Code:

Public Class Form1
      Public MyAccessibleVariable As String = String.Empty
      Public Sub ButtonClick(sender blah blah...) Handles blah
          MyAccessibleVariable = MyButton1.Text
      End Sub
End Class
 
Public Class Form1
      Public Sub SomeMethod()
          'Assuming Form1 is instantiated
          MessageBox.Show(Form1.MyAccessibleVariable)
      End Sub
End Class
