There's no PDF support in C# , you need to find a library to do that, probably paid, but free ones exist. Your screen should look like this: You can create some rather complex workflows in this manner. However, it is limited in the following ways. First, although there is a mechanism for executing C# code from within the workflow when invoked in this way, it s far preferable to create custom assemblies that, if nothing else, house the code you want to execute. And second, you can t pass parameters into the workflow without first creating a custom root activity to accept them. At some point in the future that might change, but for now this is how WF operates. We ll create a custom assembly for this purpose later in the chapter. However, an intermediate step is to compile your XAML-based workflow into an assembly you can reference for execution. To compile the XAML-based XML, we ll use the workflow compiler, wfc.exe. 3: merge pdf using c#: How to merge multi pdf files in one pdf ? - CodeProject remove pdf password c# How to read PDFs created with an unknown random owner ... - iText

The CompiledXmlWorkflow application is incomplete, but it only requires the workflow definition. The CompiledXmlWorkflow Completed version is ready to run. If you d like to follow the steps I ve outlined here, open the incomplete version. If you d rather follow along but not type code or drag activities, then open the completed version. To open either version, drag the .sln file onto Visual Studio and it will open it for you. 2. Add a new Workflow1.xml file as you did in step 2 of the preceding sample. Because you ll be compiling the workflow with the workflow compiler, you don t need to change the compiler settings for this file (steps 3 and 4 of the preceding section). 3.
