Writing RTF control words

[longtrails]

I'm trying to create a header with page numbering in an RTF file. Using a text editor I can enter '{header Page chpgn}' and get my page numbering. If I use _GUICtrlRichEdit_AppendText to add it characters are escaped and it is displayed as simple text (which makes sense). Looking at the source for _GUICtrlRichEdit_AppendText and the ReadBmpToRtf example I tried enclosing that with '{rtf }' or '{rtf1 }' but nothing gets written to the RTF file and @error is 0 coming out of _SendMessage. I'm a bit stumped.

Welcome to the forum

This borders upon being brute-force, but works:

$sFileName = @ScriptDir &  "\test.rtf"

$sData = FileRead($sFileName)
$sData = StringReplace($sData, "\pard", "{\header Page \pard\qr\chpgn\par}\pard", 1)

$hFile = FileOpen($sFileName, 2)
FileWrite($hFile, $sData)
FileClose($hFile)

Thank you for the welcome and for the snippet of magic. I am still at a loss as to how the ReadBmpToRtf example found in the AutoIt help will work but my approach won't but your brute-force approach is better than a punch in the mouth!
