Open the Solution Explorer pane in Visual Studio, find the EXE project branch and right click it. In the drop down list that appears is "Set as Startup Project". Click that, and the EXE will run when you debug.

But normally, if you got code from an article, then there is a "Add a Comment or Question" button at the bottom of that article, which causes an email to be sent to the author. They are then alerted that you wish to speak to them.
Posting this here relies on them "dropping by" and realising it is for them.

I tried both approaches, "bold Single" and multiple. I get the same error either way. I am using VS2019, is that a problem?

I just tried VS2017 and after I got the original error the following error showed up: "HTTP Error 403.14 - Forbidden
The Web server is configured to not list the contents of this directory."

Any ideas?

Can you tell us which CodeProject example you are using ?

Which article are you talking about?

CP doesn't write the articles. They are written by people who volunteer their time. If you've got a problem with an article, there's a forum at the bottom of the article to ask questions about it.

If you created the projects yourself, it's entirely possible you created one of the projects with the wrong project template.
