Call C# BHO method from javascript
bho, c#, com, internet-explorer, javascript
Solution
I've the same problem. And the following fix seems work in my BHO:
dynamic window = _webBrowser.Document.parentWindow;
var windowEx = (IExpando)window;
PropertyInfo p = windowEx.AddProperty("myExtension");
p.SetValue(windowEx, this);
instead of:
dynamic window = _webBrowser.Document.parentWindow;
var windowEx = (IExpando)window;
PropertyInfo p = windowEx.AddProperty("myExtension");
window.myExtension = this;
Problem
I need to call a C# BHO method from javascript I have followed the solution given in this question I get the error: ``` 'mshtml.HTMLWindow2Class' does not contain a definition for 'myExtension'. ``` I cannot assign: ``` dynamic window = browser.Document.parentWindow; ``` as parentWindow is undefined, I have to cast to (mshtml.IHTMLDocument2) and (mshtml.IHTMLWindow2) Does anyone have a full working example I could refer to or any help or alternative solutions
