Hi!
In order to monitor this variable value, do I need to put this variable within a loop?
Thanks.

Hi victor
Make the call to the URL of the service (Look above the workflow for this). Something like this:
In this example I have a folder called Examples with a workflow called Handler in it which is the workflow you can see on the design surface. In the Variables list on the right, I have set the two variables I want to use as Input so they can be accepted by the workflow. After that, I just use them, as in the decision.
Hope that helps.

Run .exe with CMD line
Hello!! I'm trying to run a .exe file, but i can't see the screen! I know that the file is open, the work flow is fine, but i can't see the screen!! where is it??
Thank you very much for you time!

Hi,
So a solution for you given your process will be for you to start the other windows form application after the workflow completes.
So in your process would become:
1. A Windows form in c#, have a textbox to validate a email.
2. The submit button executes the workflow
3. The workflow do all the process and create a file with the result.
4. C# application from step 1 will start the next C# application after the workflow completes
Does this solution work for you? We will discuss your idea for the CMD line tools and possibly add it as an option.
Thanks
