We have implemented PDF Signing using functions - NewSignProcessFromFile() and EndSignProcessToFile() and we get the result of the signing with GetSignProcessResult(). 

The problem we ran into is this: 
A user is trying to sing a PDF File. 
The certificate he chooses ha s a password so Windows shows a dialog to enter the password. 
If the user at this time chooses to not enter the password, he click on [X] or Cancel - The password dialog shows again. The user cancels again. 
After the second cancel the function EndSignProcessToFile() returns but the output file has a new signature (invalid signature) and the function GetSignProcessResult() returns 1 (succesfull signing). Here is the problem. 

Is there a bug in the GetSignProcessResult()? 
And is there a way to find out if the user entered his password or not?
