Question webbrowser and javascript vb.net ? - D3ath_GuN - Oct 9, 2019

Hello,

I would like to know how to make javascript scripts work with the webbrowser.
Because, I made a small program under vb.net to infect via a web page that mine "jsecoin" + "Pop up"

I would like to know how I make it work?

I used this code to block JavaScript error messages.

Code 
WebBrowser1.ScriptErrorsSuppressed() = True

May I ask a few questions?
What do you mean by "to make javascript scripts work with the webbrowser" ?
As far as I know, the Webbrowser control is actually IE. And if your IE supports/ JS enabled then you should be fine.
And for the code :

Code 
WebBrowser1.ScriptErrorsSuppressed() = True

Try inserting that line on the program's load event.

Are you asking how to inject JavaScript in websites using the default browser of a user or how to use JavaScript in the Webbrowser control? I can't quite tell from your post. Either way, the default Webbrowser control duplicated the Internet Explorer web browsing functionality which is not something you'd want in this day and age. The reasoning behind this is that JavaScript has evolved since Internet Explorer last released and modern versions of JS simlply won't work or display various error messages for which you'd have to transpile your JavaScript to work with older webbrowsers. Besides that, the WebBrowser control is a very resource-hungry control.

I would suggest that you look at other libraries to get up-to-date webbrowsing functionality or instead utilize the power of already existing browsers, in which case I suppose that what you're doing may be considered illegal, depending on what you'd use this for, so I'm not going to provide any more assistance than this.

IE may have some settings in a registry key for this

Not possible.

I can recommend you looking in to Selenium for .NET instead.
