O que é adcjavas.inc?
Este arquivo contém constantes do ADO que são usadas para scripts do lado do cliente com o Microsoft JScript.
Microsoft JScript does not support type libraries, so you do not need to reference ADO in your project. Consequently, no associated features such as command line completion are supported. Also, by default, ADO enumerated constants are not defined in JScript.
However, ADO provides you with two include files containing the following definitions to be used with JScript:
For server-side scripting use Adojavas.inc, which is installed in the c:\Program Files\Common Files\System\ado\ folder by default.
For client-side scripting use Adcjavas.inc, which is installed in the c:\Program Files\Common Files\System\msdac\ folder by default.
