Protect images in RichViewEdit

Hi,
I'm using a RichViewEdit to add text and images in it. I'd like to know how I can protect images that I paste in it.
Currently, I use this code to protect the whole text I have in the RichViewEdit and that works fine.
Code: Select all
SRichViewEdit.RichViewEdit.Controls[iNbControls]).SelectAll;
SRichViewEdit.RichViewEdit.Controls[iNbControls].GetSelectionBounds(mStartItemNo, mStartItemOffs, mEndItemNo, mEndItemOffs, True);
while ( mStartItemNo <= mEndItemNo ) do
begin
SRichViewEdit.RichViewEdit.Controls[iNbControls].RVData.GetItem(mStartItemNo).StyleNo := 6;
mStartItemNo := mStartItemNo + 1;
end;
The problem is when I run this function, the image I pasted in the RichViewEdit becomes invisible and I can't save this image anymore.
I'd like to know if there's any solution to my problem.
Regards,
- Charles

I do not understand what is "Controls[iNbControls])." in your code.
But apart from that, the main problem in your code is assigning a text style (6) to non-text items (items having StyleNo<0, that must not be changed).
The simplest solution for applying the 6th text style is
Code: Select all
SRichViewEdit.RichViewEdit.SelectAll;
SRichViewEdit.RichViewEdit.ApplyTextStyle(6);
This code protects all text, but does not protect non-text objects like pictures. For non-text objects, call
Code: Select all
SRichViewEdit.RichViewEdit.SetItemExtraIntProperty(i, rvepDeleteProtect, 1);
SRichViewEdit.RichViewEdit.SetItemExtraIntProperty(i, rvepResizable
, 0);

If you need to protect the whole document, you can assign SRichViewEdit.ReadOnly := True;

I've tried what you told me and that works fine except for one thing.
I apply a protected text style to the whole RichViewEdit and I protect every images and that works fine, but when I put my cursor on the right or left of an image, I can still enter some text...
Is there a way to prevent this as the property ReadOnly is not something I want to use in this specific project.

You can protect the whole paragraph by including rvpaoReadOnly, rvpaoStyleProtect, rvpaoDoNotWantReturns in Options of its paragraph style.

Those paragraph style properties work fine to prevent inserting before and after an image, but now I can't add some text to the end of that paragraph.
When I apply a textstyle without the property StickToBottom, that allows me to add some text at the end of the item, but when I apply the paragraph style I lose that possibility.
Is there a way to prevent user from inserting text before and after an image while allowing him to add some text at the end of the paragraph?

I am afraid no, the current version does not allow it.
(you can exclude rvpaoDoNotWantReturns, and the user will be able to add new lines by pressing Enter while at the beginning/end of the paragraph, but modifying the paragraph is still not possible)
