Does your application support gif images? See here: http://www.trichview.com/forums/viewtopic.php?t=89

Well, I can see that the problem is not in gif, but in invalid file name. Obviously, D:\Project\http:\<site>\logo.gif is not a valid file name.
Please send me these files, I'll try to see what's wrong.

1. What page (URL) do you copy from?
2. What browser do you use for copying?
3. Do you paste in HTML format using TrvHtmlImporter, or RTF (without using it)?

IE 7, FF3

I copy directly from page to clipboard and than paste to RichViewEdit

I don't know how to make it, but I just want to save HTML page with copy-paste operations
I don't care about styles and CSS. I just want pictures and text saved to RV

thanks

I cannot reproduce this problem when copying from www.trichview.com.
When I copy from IE7 to to RichViewEdit without assigned events, it attempts to load pictures from their original locations (such as "http://www.trichview.com/images/headers/news.gif"). Of course it fails because images need to be downloaded.

Or may be you paste into ActionTest demo with Indy support turned on?
What version of TRichView do you use?

In order to help you, I need a detailed instructions how to reproduce this problem, because all works fine on my side.

ok, can you advise me what actions should I do to download images, save them in temporary files and than paste in RV as it looks on web-page?
may be there is an example somewhere?

I thik that main issue is "it fails because images need to be downloaded"

If the problem was because images not downloaded, the error message would be like 'Cannot open file http://www.somesite.com/logo.gif', i.e. picture name would be a correct URL...
I recommend to update to TRichView 11. It has some fixes when importing documents with external images.

As for downloading.
If you use RichViewActions, they do this work automatically. Just enable support for Indy: http://www.trichview.com/help-actions/indy.htm

If you do not use RichViewActions, process RichViewEdit.OnImportPicture event. In this event, if the path parameter is a http location, download the image in a temporal location (using TIdHttp component, for example), then insert this picture. I currently only have an example with TrvHtmlImporter ( http://trichview.com/resources/html/rvhtml_indy.zip ) This example uses TrvHtmlImporter's event, so it needs to be corrected to use RichViewEdit.OnImportPicture.
