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。

Descriptive text for any error code can be obtained using the ErrorText property. Some codes that could encountered (this is not comprehensive) include:

71 – “The maximum number of CAEngine instances allowed are already in use”

72 – “Invalid license code”

73 – “Stale license code”

74 – “Expired license code”

75 – “No ADE license code is present”

76 – “Not an application license code” (from SetApplicationLicenseCode method)

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.
