ExtractAsyncData Method
Extracts user data from the DC signing service response.
Syntax
ANSI (Cross Platform) char* ExtractAsyncData(const char* lpszAsyncReply); Unicode (Windows) LPWSTR ExtractAsyncData(LPCWSTR lpszAsyncReply);
- (NSString*)extractAsyncData:(NSString*)asyncReply;
#define MID_PDFSIGNER_EXTRACTASYNCDATA 3 SECUREBLACKBOX_EXTERNAL int SECUREBLACKBOX_CALL SecureBlackbox_PDFSigner_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);
Remarks
Call this method before finalizing the asynchronous signing process to extract the data passed to the ExternalCrypto.Data property on the pre-signing stage.
The Data parameter can be used to pass some state or document identifier along with the signing request from the pre-signing to completion async stage.
Error Handling (C++)
This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its 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.
