Hi,
1. In IE I can get the web page document so oIE:GetProp("Document"). Can I do this in WebView ?
2/ There is a Navigate method in the WebView class. Is it possible to use it to download HTML text from a file ?
3. When I launch WebView, a standard window opens. Is it possible to change its type to PopUp ?
4. Is it possible to embed this window in a window with an FW application (in the specified coordinates) ?

2. Simply use this code in your HTML:
<a href="test.txt" download>Click here</a>

3 and 4.:
Class TWebView provides a Method SetParent( oWnd ) so you can make it child of any window, dialog or control

In I create a WebView and in the script I open a new page
var pdg= new URL('MyPage') ;
I need to return some data to the FW on the page URL change event. How can I do this?

Dear Yuri,
When you use this code:
viewtopic.php?p=255632&sid=1d500740664e0671278e8d3f3076d61a#p255632
you can call SendToFWH( params... ) from the web HTML javascript and your FWH app will get it on the oWebView:bOnBind codeblock

1. Is it possible to ask for an example script in the method :Eval() of several lines
2. Why the method is needed :setHtml if you can't write a JS script in it ?

Dear Yuri,
> 1. Is it possible to ask for an example script in the method :Eval() of several lines
Call a function from inside the codeblock where you can easily use multiple lines of code
> 2. Why the method is needed :setHtml if you can't write a JS script in it ?
Of course that you can use JS script in the cHtml that you provide to Method SetHtml(). I am going to provide you an example

A good example !
What is the method for :oWebView:SetUserAgent(), the program also works without it ?

Dear Yuri,
Method SetUserAgent() is a workaround to be able to login into your goggle account.
Without it you can't login into gmail, etc

Can I use WebView to do the following:
a) Open a page
b) find an item on this page
c) click on this item
All this is easy to do via IE (Activex), but it does not work on WebView
