Using InvokeScript with a WPF browser application

Can someone explain why I'm encountering the error (Exception from HRESULT: 0x80020006 (DISP_E_UNKNOWNNAME)) when trying to call a javascript function in a WPF application (.Net 4)?

The application hosts a browser control and utilizes local html files, for example:

C:\Users\XXXX\AppData\Roaming\XXXX\Books\XXXX_revision_1_1\html\1\med-9780198569244-chapter-4

Within this file, there is a javascript include called 'script/scripts.js'

Is it feasible to use C# to trigger a javascript function through the InvokeScript method on the browser control when the URL points to a local file?

c#javascriptwpfwebbrowser-control

Answer №1

The reason why I was mistaken is because I was making the call too early. It should actually be done after the page is fully loaded.

Referencing MSDN - http://msdn.microsoft.com/en-us/library/cc491132.aspx

'InvokeScript(String) should not be called before the document that implements it has finished loading. You can detect when a document has finished loading by handling the LoadCompleted event.'
