Answer 1

What you report is not the whole story. Take the following steps:

1. Create a new VCL forms project.
2. Add a TWebBrowser component to the automatically generated form.
3. Double click on the form to create an OnCreate event handler named FormCreate that is associated with the OnCreate event.
4. Put your call to WebBrowser1.Navigate into the body of the FormCreate method.
5. Run your application and observe that the browser control displays your page.

In other words, something else in your application is blocking this. Perhaps the OnCreate event handler is not assigned to FormCreate . Or perhaps something else is wrong. However, you can follow the steps above to prove to yourself that navigating from OnCreate works. Then all the remains is to diagnose where your application differs.

The bottom line is that calling Navigate from an OnCreate event is sufficient to show a web page on form startup.
