There is a similar question how can a password -protected PDF file be opened programmatically? I copied some part of that question and put it ... 8. Save the file. The entire TruckServiceDataConnector class is shown in Listing 17-2. Again, keep in mind that the purpose of this class is to store correlated data coming from the various workflow instances. The data is stored in a Dictionary object, the key for which is an amalgam of the workflow instance identifier and the truck identifier. Therefore, the data is keyed in a correlated fashion. The data connector class is a singleton service in the workflow runtime, so we have registration methods the individual workflow instance data services will use to identify themselves and establish their presence as far as data communication is concerned. Note You might wonder why the data being transferred is in XML rather than the data objects themselves. WF doesn t serialize objects when passed between workflow and host, or the reverse. As a result, copies of the objects are not created (undoubtedly to boost performance). Exchanged objects are passed by reference, so both workflow and host continue to work on the same object. If you don t want this behavior, as I did not for this sample application, you can serialize the objects as I have or implement ICloneable and pass copies. If this behavior doesn t affect your design, you don t need to do anything but pass your objects back and forth by reference. Keep in mind, though, that your objects will be shared by code executing on two different threads. remove pdf password c#: Code for making pdf to password protected pdf in c# windows ... how to generate password protected pdf files in c# Itext 7 - PdfReader is not opened with owner password Error - Stack ...
