CALicense::ErrorText

ADE User Guide > ADE Server Class Reference > CALicense

property string CALicense::ErrorText

来自前面CALicense方法调用失败原因的的状态代码。尤其是，在调用NewCAEngine方法后，这提供了关于失败原因的信息。

错误代码能通过使用ErrorCode属性获取。一些代码可能会遇到（不全面）：

71 – “使用的CAEngine实例数量已达到允许的上限”

72 – “无效注册码”

73 – “过期注册码”

74 – “到期注册码”

75 – “没有安装ADE注册码”

76 – “非应用程序注册码” （来自SetApplicationLicenseCode方法）

The CAEngine object has property with the same name (and it uses a consistent set of error codes with this one). Once you have a CAEngine instance, you will need to check its ErrorText property -- not the ErrorText property of the CALicense. Use this CALicense::ErrorText only to catch errors during instantiation of the CAEngine.
