What is app.helpfile in vbnet?

Answer 1

For providing context-sensitive help to VB5 and Vb6 applications, we can set the property called App.helpfile and hook-up the helpfile with the application.

For VB 5 and above one can use .hlp files as help files. For Vb6 and above one can use .chm files as application help files.

In VB.NET this property is not used for providing F1 help to the applications. Instead a control named - Helpprovider is dropped on the form and configured for associating help topics frm the .chm file to the form controls.
