C# Winforms -> How to have execution wait until page load complete?

[Shaareable Apps]

Greetings,

I'm writing an app for my wife that has to spends countless hours everyday struggling with a primitive, ugly website designed in the 90's.(consultant page for Usborne's kids books).

The goal is to automate much of the drudgery. Everything is going smoothly so far, I can scrape the sucker, but there's one key thing I'm missing.

How do we know when the page load is finished?

I once code an excel vba app and that ie programming was simple enough.

Please tell me we have a way here to get the status 200! :)

Thank you kindly from Vancouver, :)

Here's what I do.  I setup the LoadingStateChanged event:
_browser.LoadingStateChanged += BrowserLoadingStateChanged;

Then in the handler, I notify that the page as finished loading:

private static void BrowserLoadingStateChanged(object sender, LoadingStateChangedEventArgs e)

{

if (!e.IsLoading)

{

_tcs?.TrySetResult(true);

}

}

tcs is a TaskCompletionSource that both the handler and my code and see:

private static TaskCompletionSource<bool> _tcs = null;

Then in the code, once I call EvaluateScriptAsync, I then do:

_tcs = new TaskCompletionSource<bool>();

await _tcs.Task;

which will cause the main thread to wait.

Hope this helps.
