I've tried the following code (C++):

bool bEmpty;

bEmpty = (RichViewEdit1->ItemCount == 0) ||

((RichViewEdit1->ItemCount == 1) &&

(RichViewEdit1->GetItemStyle(0) == 0) &&

(RichViewEdit1->GetItemText(0).Trim() == "") &&

(RichViewEdit1->GetItemStyle(0) >= 0) &&

(RichViewEdit1->GetItemPara(0) == 0));

if(bEmpty == true) Caption = "RichViewEdit is empty";

else Caption = "RichViewEdit isn't empty";

//---------

It doesn't work when I copy an Image, table and text from MS Word with CTRL+C

to RichViewEdit. And then delete the text from RichViewEdit.

What I want is as follow:

I want to save documents automatic. But I don't want to save empty documents.

With empty documents I mean: no visible text, images, tables, etc..

In the past I used RichEdit. I used the following code:

if(RichEdit1->Text.Trim() != "") Bla, Bla, savemyfile...;

Thanks.

>(RichViewEdit->GetItemStyle(0)>=0). It depends on what do you mean by "empty
