How do I make a variable available to another form?

  One option is to stored your variable in the session cache.

  ' This method does not require navigation between the two pages

  ' and will persist the object in the cache until removed

  ' add an item to the session cache on page one

  Dim myObj As Integer

  Session.Add("myItem", myObj)

  ' retrieve on a different page

  Dim retrievedObj As Integer

  retrievedObj = Session.Item("myItem")

  If Not Nothing = retrievedObj Then

  ' do page logic based on available variable

  ' remove from cache

  Session.Remove("myItem")

  End If

  Almost any variable you can make you can use with Settings. Use Configuration Settings (go to the application's properties, then the settings tab) to store variables such as integers, boolean variables, strings, whatever...and you can choose to save it forever or just for the lifetime of the current application instance. They are very convenient. Try it out.
  
  Edit 1: I forgot this was Visual Basic. You can access settings by going to My.Settings

  declare the variable global (in a module) you can access it every where.

  or else you can make the variable in the form as public and access it in another form as <form name>.<variable name>

  or else creating property you can access all the variable in the form.

  Another way I guess would be to make a class/module static so you can set variable as required and let other forms access it without passing references. There are a couple of ways to go about it but hope the above link will help you at least

  Could you elaborate on the Public methood I have tried this and I'm getting a warning stating that the variable is not part of the user control.

  As per the example provided if you are actually using an type of integer you would actually check for non zero value as the integer will be initilaised as zero.

  If retrievedObj > 0 Then

  End If

  winforms dont act/have webform features - Session() is for webforms, not winforms
