Need a simple code VB .Net

Hi, We are building a software which is on VB .Net It uses a WebBrowser item. We enter the values programmatically through the script, the issue is that we need to "Click" the submit button programmatically which is seems to be ga or something. We need the piece of code script how to send a command to the webbrowser to submit the button. Here's the button script from the website code: <button onmouseover="ga('send', 'event', 'OnMouseover', 'Nav', 'Login');" onclick="ga('send', 'event', 'OnClick', 'Nav', 'Login');" type="submit" class="js-login btn btn-block btn--primary btn--sm btn--block login-panel__login-btn">Login </button> If you're able to provide the piece of script that can do the submit, please apply.
