WebView2WebView->Navigate requires full URL?

[douglas-jordan]

It seems in the sample and in my own code when calling WebView2WebView->Navigate the URL must be a full URL such as "https://www.whatismybrowser.com". If you specify a string like "www.whatismybrowser.com" the function fails with an invalid arguments error. In the WebBrowser control you can specify any sort of string for the URL and the control parses and resolves it correctly.

Will the release version add this partial URL resolve functionality to WebView2WebView->Navigate?
Without this it is a severe drawback to existing code where the WebBrowser IE control works easily.

After further study, I see there are differences with URL and URI. I needed backwards compatibility for existing stored urls so I created a simple check that can append the http:// as needed with this routine. See below for reference. If you use this code you may need to change the size value for the url var, my stored urls will always be less than 500 characters.

HRESULT NavigateURLWebView2(IWebView2WebView* webview, LPCWSTR uri)
{
	WCHAR url[500];
	LPCWSTR purl = uri;
	// Check string for :// because webview needs a complete URL or URI
	// we care about http:// or https:// or file:// anything else should have the protocol specified
	if (wcsstr(uri, L"://") == 0)
	{
		// check for local file with a colon as the second character as in C:\path\to.html
		// else its a URL and add http and most sites will redirect to https
		if (uri[1] == L':') wsprintfW(url, L"file://%s", uri);
		else wsprintfW(url, L"http://%s", uri);

		purl = url;
	}
	return(webview->Navigate(purl));
}
