We have a Web Forms application made with Activix and itextsharp.dll, framework 4.5.1, signing a PDF document when squeegee the application on my machine works or application runs on the server and access the server remotely also works, however when I publish it Windows Server and access the application via the link only works until the time that the application requests the client's browser certificate but when will display the box to enter the password (pin) token (A3 - USB) does not show. In AClass.cs class has the Itextsharp.dll method that calls the Pin - MakeSignature.SignDetached ();
They can help me? follow what I got so far.
Note: If you want to test is the need to generate a dll AClass.cs class and references the itextsharp.dll do from the command line, we need to put the "itextsharp.dll" and "AClass.cs" class in the folder that the executable "CSC", follows the code.
( \Windows\Microsoft.NET\Framework\v4.0.xxxxx
csc /t:library AClass.cs /r:itextsharp.dll
regasm AClass.dll /tlb /codebase )
