OnDocumentComplete - EmbeddedWB

Alfred · 11-10-2009, 06:21 PM

Why does TEmbeddedWB fire an OndocumentComplete upon startup without anything loaded ?

If I have a form with just the TEmbeddedWB on it, it fires an OnDocumentComplete when starting the application.

Now when I want to load a local file it fires the event twice, giving me errors because during the first event firing the file isn't actually loaded, only during the second event firing....

Can't put my finger on this....

[Edit]
I just checked, but TWebBrowser does not have this behaviour..

I have the same behaviour with the latest build. Seems like the TEmbeddedWb autonavigate to about:blank during creation.

Yeah, my program was suddenly broken...
Can't remember any problems with previous builds either.

1. Open EmbeddedWB.pas

2. Go to

Code:

 
procedure TEmbeddedWB.HTMLCodeChanged(Sender: TObject);

3. Replace

Code:

 
      LoadFromStrings(HTMLCode);

with

Code:

 
      if HTMLCode.Count <> 0 then
        LoadFromStrings(HTMLCode);

Hope that helps
