捕获嵌入winform的网站上发生的事件

Question

I have a web page that is embedded in my winform.

When i click a button on my application the form shows up and navigates to a settings page.

What i want is to catch an event fired on the website. eg if the user changes some settings on the webpage and clicks OK then i should catch that even and close my form automatically.

Is this even possible?

Here is the JS code for the OK click event

if (statusOK) {
Ext.Msg.show({
title : '',
buttons : Ext.Msg.OK,
msg : 'Default settings saved.',
 icon : Ext.Msg.INFO
}); 

Any help will be appreciated.

Thanks

Answer 1

In your web page, you can do a redirect to some specialy crafted URL, like myapp://doStuff.

And in the web browser control, you can subscribe to Navigating event that will be fired when page tries to go to another URL. In that handler you can detect your specially crafted URLs and execute needed actions.

You can do the following in javascript

 window.external.MyFunction();

That will call the MyFunction() function in winforms.

In your cs file you need:

[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]
[System.Runtime.InteropServices.ComVisibleAttribute(true)]

before your class definition. And MyFunction() needs to be public. In that function you can do to your form whatever you want.
