Information Bar
The information bar is one of the windows of the Validation’s user interface; when the program starts, it is located
above the field source bar (which displays the field’s snippet), but it can be moved around like any another window.
This information bar can be filled by software, in order to display messages to the validation operator. To do so,
there is a class
StatusTextTransporter. Define an object of this class (preferably as a global variable) and use
its
Text property to display a text:
Option Explicit
Public infoBar As New StatusTextTransporter
Private Sub Application_OnProjectLoaded(ByVal App As Application)
infoBar.Text = "Hello InfoBar"
End Sub
While the
Text property displays the text in a standard format and size, the HtmlText property allows you to
format the text individually by using standard HTML tags. The following example will display the text bold,
enlarged, and in italics:
Option Explicit
Public infoBar As New StatusTextTransporter
Public WithEvents DateField As FieldType
Private Function DateField_OnFieldChanging(ByVal Field As Field, ByVal SubField As Field, _
ByVal VerifyEventArgs As VerifyEventArgs) As Boolean
DateField_OnFieldChanging = True
If Not ValidDate(Field.Value) Then
infoBar.HtmlText = "<b> <h1> <i> Invalid Date </i> </h1> </b>"
End If
End Function
Private Function ValidDate(fieldValue As String) As Boolean
'* code to check the format
End Function
The result will look like this:
