    Mathematical symbols do not display in RTF file

    My application opens a RTF-file with maths papers which I created with MS Word. The font was Times New Roman and I inserted a couple of symbols like triangles, greater than-, not equal to-, etc. from the "Insert - Symbol" menu.
    When I open the rtf documents with Wordpad, the symbols are correct.
    When I open the rtf documents with my VB application, the symbols are displayed totaly different, like question marks, squares, etc.
    How can I fix this problem?

    Those characters are part of the extended ASCII chart. Maybe the RTF control can't display them?

    On a side note, this would probably be better answered in the General VB forum

    Yes, I know, I tried it, but I could not get a solution in that section.
    The RichTextBox displays the symbols correctly when I use Win XP, but not on PCs with Win 98 and Win ME.

    Check the version of the OCX on each machine. If they're different, try backing up the Win98/ME version and replacing it with the WinXP one.
