  Hi,
  
  Can you give an example of what you're trying to do?
  A possibility...
  In Base Form declare a Protected Boolean variable
  
  Protected bLoading As Boolean
  
  This variable will be accessible in the base form and in the inherited form
  
  : How do I get a true boolean value from an inherited form to my main form?
  : What function do i use???????

  : Thx

  Hey,
  Well I was making a program and an options menu, so that is another form. And i want the user to check a checkbox to say if he wants to clear a box every time a math problem is solved... I am making a calculator. For now i have just made the checkbox in the same form as the main form, so its no problem. Help?????

  Hi,
  
  One method to save and retrieve application settings is by storing them in the registry by using GetSetting and SaveSetting.
  
  For example,
  
  'On the Close/Save of your options form...
  Private Sub btnClose_Click('Arguments) Handles btnClose.Click
  Dim sValue as string
  
  If chkClearBox.Checked then
  sValue = "TRUE"
  else
  sValue = "FALSE"
  end if
  'Save to Registry
  SaveSetting(sAppName, "Options", "ClearBox", sValue)
  End Sub
  --
  'Somewhere in the Main Form code
  Dim sValue as string
  
  'Retrieve From Registry
  sValue = GetSetting(sAppName, "Options", "ClearBox")
  If sValue = "TRUE" then
  'Code to Clear Box
  else
  'Do not clear box
  end if
  
  ***Please note that sAppName refers to the name of the application that you're running. You can retrieve the name of the application with the following code.
  
  Dim s as string
  
  s = System.Reflection.Assembly.GetExecutingAssembly.GetName.ToString
  sAppName = s.Substring(0, s.IndexOf(","))
  
  ***Another option might be to research the capabilites of adding an App.Config file and store values there rather than the registry.
  
  Hope this helps,
  
  Chris

  Hi, Thanx for that code but i just used a public boolean in a module then i just used that value to see if i could triffer. But i'm kinda new to all this .net stuff. Still 12 years old. I started about 3-4 weeks ago. I just happen to know the basic stuff. From the GUI to a litte bit of coding.
  
  Thanx anyway,
