Search in RichEdit 5

[Natter]

Hi,

Search in RichEdit5. I need to find in it all the positions of underlined characters on a white background.
Is it possible to do this ?

hi Natter,

i "think" that "commdlg_FindReplace" also work with RTF

Problem : Fivewin have "only" CLASS TDlgFind ( c:\fwh\source\classes\dlgfind.prg )

---

have "begin" to re-write HMG for FiveWin to REDIFEINE "commdlg_FindReplace"

Hi Jimmy,

Thanks for the help. I think to do so:
1. Open an RTF document via OLE and do a search (via VBA) for all underlined characters to get an array of their positions.
2. Upload an RTF document to RichEdit5 and color it according to the parsing of its structure. At the same time, I also get an array of colorized characters
3. Compare these 2 arrays
