| Name | Description |
|---|---|
| GeneratePassword(Integer, Boolean) | Generates and returns a password string of length 'l'. If 'alpha' is True the string can contain both digits and letters, if False the string can only contain digits. The generated password string is a random combination of letters and digits, or just digits, depending on 'alpha'. |
| If(Boolean, Generic, Generic) | Returns 'true_return' if 'value' is True, otherwise returns 'false_return'. The return data type of the function is the type of 'true_return' unless there's an implicit convertion from 'true_return' type to 'false_return' type. When there's no implicit type conversion an invalid data type error will occur. |
| IsLoadingScreen() | Returns true only when invoked within a screen Preparation execution and only if the screen is loading its content. Otherwise, if the screen is just being redrawn, i.e. posted back, it returns False. |
| CurrentThemeIsMobile() | Returns true when the current web screen is using a mobile theme. |
