What's new in sVB v2 ?

1. Each project can contain a Global.sb file. You can create it just by double-clicking the Global.sb item in the project explorer.
   In this file, you can declare global variables, subroutines and functions that you can use in any form in the project via the Global type, such as Global.DoSomething()
   See the Show Random Buttons 3 and Show Dialogs apps in the samples folders.

2. The toolbox got a new ComboBox control.

3. Controls got RightToLeft, ToolTip and Errors properties.
   The Error property sets the error message to display in the tooltip of the control while its borders becomes red. You can restore the normal state of the control by setting the Error
   property to an empty string.

4. Controls also got the OnGotFocus and OnLostFocus events, so, you can use the OnLostFocus event with the Error property to provide a validation logic for input controls. Each control also has the Validate method that fires the OnLostFocus event to execute your validation logic (if exists), then checks the Error property and returns True if it is empty. And to make things easier for you, the Validate method of the form calls the Validate method of each control on the form. If any controls has errors, the process stops and the focus goes to this contols with a beep sound. So, you should call Me.Validate before you execute you app logic. Ex:

Sub Button1_OnClick()
   If Me.Validate() Then
      Me.ShowMessage("OK", "")
   EndIf
EndSub

But if you want to do anything else when a control input is not valid, you can validate each control your self:

Sub Button1_OnClick()
   ForEach control1 In Me.Controls
      If control1.Validate() = False Then
         Sound.PlayBellRing()
         control1.Focus()
         ' Do more things here if you want
         Return
      EndIf
   Next
   
   Me.ShowMessage("OK", "")
EndSub

For a full example, see the Validation app in the samples folder.

1. sVB now tries to infer the type of an expression, and the type of the function return value.
