I need to be able to press the source Listen button and the Listen button of the translated language.

There's no element ID.

What I have tried:

try
            {
                foreach (HtmlElement h in webBrowserGoogleTranslate.Document.All)
                {
                    

                    if (h.InnerHtml == @"<div class=""jfk-button-img""></div>")
                    {
                        h.InvokeMember("MouseDown");
                        h.InvokeMember("MouseUp");
                        h.InvokeMember("Click");
                    }
                    
                }
            }
            catch { }

Solution 1

There are two Listen buttons (source language and destination language). The unique characterisation of these buttons is that they are a div element with src-tts as class for the source and res-tts for the result (amongst other classes). So loop over the elements and check for said class:

C#

HtmlElement sourceListenButton = null;
foreach (HtmlElement h in webBrowserGoogleTranslate.Document.GetElementsByTagName("div"))
{
    if (h.GetAttribute("class").Contains("src-tts")) // or res-tts; Contains because there are other classes too
    {
        sourceListenButton = h;
        break;
    }
}

if (sourceListenButton == null)
{
    // not found
}

listenButtons remains an empty list...

I posted an alternative that you can try, but currently I don't have the chance to actually test it myself.

Sorry still 0.

Are the buttons already visible in the control at the time you call this code?

john1990_1 2-Jan-19 11:41am

Yes

I'm out of ideas then, for now. Perhaps I'm able to test it tonight...

I think I may have found the cause. The value isn't "Listen" of your Google interface is not English. Please try my current code.

john1990_1 2-Jan-19 12:07pm

It's English.
Still null...

I wanted to test it but unfortunately I couldn't even fully render the document. All I got was a "Translate" header and a bunch of script errors...
