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。
The error number can be obtained using the ErrorCode 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 ErrorText property -- not the ErrorText property of the CALicense. Use this CALicense::ErrorText only to catch errors during instantiation of the CAEngine.

CALicense lic = new ADE.CALicense();

return
}
