SignExternal Method
Signs the document using an external signing facility.
Syntax
ANSI (Cross Platform) int SignExternal(); Unicode (Windows) INT SignExternal();
- (void)signExternal;
#define MID_OFFICEQUICKSIGNER_SIGNEXTERNAL 7 SECUREBLACKBOX_EXTERNAL int SECUREBLACKBOX_CALL SecureBlackbox_OfficeQuickSigner_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);
Remarks
Call this method to delegate the low-level signing operation to an external, remote, or custom signing engine. This method is useful if the signature has to be made by a device accessible through a custom or non-standard signing interface.
When all preparations are done and hash is computed, the class fires ExternalSign event which allows to pass the hash value for signing.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
