CALicense::ErrorCode
ADE User Guide > ADE Server Class Reference > CALicense
property int CALicense::ErrorCode
来自前面方法调用的状态代码(失败原因)。尤其是,在调用NewCAEngine方法后,这提供了关于失败原因的信息。
任何错误代码的描述性文本都能通过使用ErrorText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 ErrorCode property -- not the ErrorCode property of the CALicense. Use this CALicense::ErrorCode only to catch errors during instantiation of the CAEngine.
