The following constants define all the possible error code values that Xceed Encryption control methods can produce. The error codes also apply to methods in the Xceed Hashing and the Xceed Signing control.
The declarations for these error codes are built into the library's "Type Library" (see the EXEError enumeration) and should automatically be accessible by your code.
Visual Basic users should use the Err object in their error handling code. It provides a textual description of the error code when needed.
Delphi users can trap the EOleException exception (include "comobj" in your unit’s Uses clause) and access any of the exception object's properties for information about the error.
| Enum | Value | Description |
|---|---|---|
| S_OK | 0 | The method call completed successfully. |

| Enum | Value | Description |
|---|---|---|
| eerNotLicensed | 0x80045001 | The license key required to use Xceed Encryption Library was not found, is invalid or is an expired trial license key.

| eerInvalidFileProcessing | 0x8004501D | Invalid file processing action for this method call. |
| eerInvalidAction | 0x8004501E | The file processing action is not supported for this method. |
| eerOpenFileForReading | 0x8004501F | Unknown error when trying to open the source file for reading. |
| eerOpenFileForWriting | 0x80045020 | Unknown error when trying to open destination file for writing. |
| eerRandomNotGenerated | 0x80045021 | The random number has not been generated. |
| eerInsufficientEntropy | 0x80045022 | The random number generated is not secure enough (insufficient entropy) because some of the system's parameters cannot be read. Please note down the operating system type and version and contact Xceed support at support@xceedsoft.com. |
