Set Backcolor

Question

Hello

Need to set a page back color for RTF files, seems that RichTextBox of Visual Studio cannot set document back color.

My RTF files are parsed from Outlook Msg files' RTF bodypart, so I saved 2 messages with and without back color and compared:

After this common command in both versions: ilfomacatclnup0

This is added to the back colored version:

"{\*\background {\shp{\*\shpinst\shpleft0\shptop0\shpright0\shpbottom0\shpfhdr0\shpbxmargin\shpbxignore\shpbymargin\shpbyignore\shpwr0\shpwrk0\shpfblwtxt1\shpz0\shplid1025{\sp{\sn shapeType}{\sv 1}}{\sp{\sn fFlipH}{\sv 0}}{\sp{\sn fFlipV}{\sv 0}}{\sp{\sn fillColor}{\sv 3506515}}{\sp{\sn fFilled}{\sv 1}}{\sp{\sn lineWidth}{\sv 0}}{\sp{\sn fLine}{\sv 0}}{\sp{\sn bWMode}{\sv 9}}{\sp{\sn fBackground}{\sv 1}}{\sp{\sn fLayoutInCell}{\sv 1}}}}}\"

The problem is that when I want to insert this back color string to other RTF files, mostly cannot find "ilfomacatclnup0" so don't know where to String.Insert the back color part to?

Also editing RTF files as text using string manipulation and File.ReadAllText / File.WriteAllText is OK or not?

Thanks :)

I think that it can be inserted just before the last “}” that closes the RTF. The sequence to be inserted is:

\viewbksp1 {\*\background {\shp{\*\shpinst\shpleft0\shptop0\shpright0\shpbottom0\shpfhdr0\shpbxmargin\shpbxignore\shpbymargin\shpbyignore\shpwr0\shpwrk0\shpfblwtxt1\shpz0\shplid1025{\sp{\sn shapeType}{\sv 1}}{\sp{\sn fFlipH}{\sv 0}}{\sp{\sn fFlipV}{\sv 0}}{\sp{\sn fillColor}{\sv 3506515}}{\sp{\sn fFilled}{\sv 1}}{\sp{\sn lineWidth}{\sv 0}}{\sp{\sn fLine}{\sv 0}}{\sp{\sn bWMode}{\sv 9}}{\sp{\sn fBackground}{\sv 1}}{\sp{\sn fLayoutInCell}{\sv 1}}}}}

Maybe it can be simplified.

The background seems to be recognized by the RichTextBox control, Word and WordPad editors.
