I have explained these points using an example. My example uses a WebBrowser control of a Windows Forms application.

"File" -> "New" -> "Project..." then select "Windows" -> "Windows Forms Application".

Step 2: Then drag and drop a WebBrowser control to the Windows Forms form and also drag and drop a Print Dialog Control onto the form.

Step 3: Then go to "Application" => "Add New Item" => "Add HTML page" to add a page to the debug folder of the application.

Step 4: Create a JavaScript function in the HTML page. Here I need to write two functions, one function without a parameter and another one with a parameter.
