Text |
When a typed text is sent by a SetPoint, it first tries to convert that value to the configured type (Word, String, Double, etc.). If this conversion is not possible, that is, the typed value is not valid for the selected type, no value is sent (for example, if users type "-1", and type is Byte). When this property's value is 0 - stCurrentType, a data type sent by this SetPoint comes from the previous value available in that object. If that previous value is Empty or Null, no conversion is performed and the typed value is sent as text. Example:
Sub Combobox1_Change()
Screen.Item("Text1").SetPointDataType = CInt(Left(Value, 2))
End Sub
