Hi Sergey,

  I have overriden rvActionPasteExecute method in my application and added

this code. This is mainly to support "paste" of HTML content.

    cf := RegisterClipboardFormat('HTML Format');

    if not IsClipboardFormatAvailable(cf) then

      rvActionPaste.ExecuteTarget(RichViewEditContent)

    else

    begin

      if Clipboard.HasFormat(CF_TEXT) then

      begin

        FStatusUpdateSplashFrm := TStatusUpdateSplashFrm.Create(Self);

        FStatusUpdateSplashFrm.lblStatus.Caption := 'Downloading images from

the internet... Please wait till we Parse the HTML and get all the

content...';

        FStatusUpdateSplashFrm.Show;

        FStatusUpdateSplashFrm.Refresh;

        try

          RvHtmlImporter.LoadFromClipboard;

          NormalizeRichView(RichViewEditContent.RVData);

          ClearCache;

        finally

          RichViewEditContent.Format;

          FStatusUpdateSplashFrm.Free;

        end;

      end;

    end;

I notice that if I use existing rvActionPasteExecute and click on menu item

paste, and if I have a content with some pictures it does not do anything

and I have to use Paste Special feature. But here we don't have option to

paste HTML content.

So I did the above code, but I see one problem. If it is normal text it's

fine, if it is an HTML content and I need to download the imgaes from some

site that is also fine. Problem is if I have a RTF content (with embedded

images) it goes in the first part of the if condition and inside

TrvActionPaste.Create method it throws an exception.

I was wondering if any one knows how to know different formats from

Clipboard content being pasted? Any link or tutorial is appreciated
