Open a cutsom chm file ribbon button

[warrenjbarnes]

I am new to the Revit API. I have gone through the first tutorials and created a button in the revit ribbon that opens the "helloworld" task dialogue. I have created a custom chm help file and would like the button to open this file instead but cannot find the code. Can anyone help?

Thanks. Warren

Try System.Diagnostics.Process.Start(filename)

Hi Warren,

You need to use ContextualHelp class to associate custom help.

ContextualHelp

contextHelp = newContextualHelp(ContextualHelpType.ChmFile, @"C:\Demo.chm");

pushButtonHello.SetContextualHelp(contextHelp);

I have posted the relevant code snippet in our AEC DevBlog -

Thanks, exactly what I was looking for

Not exactly what I was after as far as I can see. I just wanted to open the chm file by pressing the button. Thanks anyway
