User Controls basic question

[Kristian Frost]

Hi,
Say I wanted to store a variable on my main form, then display it, or
react to it, on a User Control I'd made.
How would I go about getting the variable from my main form to the User
Control?
Perhaps I want to put this variable in a textbox on the User Control and
send the data back to the main form when the user changes it. How would I
get the message of the change back to the main form?

Sorry if these are strange or hilariously basic questions, but the book
I'm using doesn't really deal with User Controls, so I have to ask here.

Re: User Controls basic question

A usercontrol can have a property, which is:-
Private MyString as String
Public Property MyProperty() as String
Get
Return myString
End Get
Set(byval Value as String)
myString=Value
End Set
End Property

or you could have
Public Sub ChangeMyString( byval value as string)
mtString=value
End Sub

then to return the string
Public Event ReturnString(by val value as string)

and in the textxchanged event
RaiseEvent ReturnString(my string)

Heh.
When I read that, I thought you were giving me a silly answer.
Turns out that, deciding that you were giving me a serious answer, and
then deciding that your way was the accepted way of accessing User
Controls, I had enough information for to work the other mysteries of User
Controls I had been having trouble with for myself.

Cheers.
