FNXBasic

There must be a problem with the RichEdit.Undo function.

Continuing on After "UNDO"ing, it pops up an "Access violation" error window.

This error also shows up on your new FNXEditor.

hi, i`ve tested it on a simple program and found no error, within the fnxeditor the error exists because the program highlights the text between ie a cut and an undo.
I will try to find a workaround to fix it.
best regards

First let me "say" that you are doing a fantastic job! I really like FNX Basic. It is easiest windows programming language I have used. (Me, "C" and "Windows" don`t get allong at all!)

I must be missing some setting in the RichEdit settings.
What am I missing to get the UNDO to work propperly?
If you need me to post the entire listing let me know. 

Below are exerpts from my program.

CODE
-----------------------------------------------------------
object meUndo as menuitem
    Caption = "Undo"
    Shortcut = "CTRL+Z"
    onclick = undo
end object

object editor as richedit
    top=0
    left=0
    width=f.clientwidth
    height=f.clientheight-21
    borderstyle=bssingle
    onkeyup = formkeyup
    scrollbars=ssBoth
end object

sub undo
    editor.undo
end sub
-----------------------------------------------------------

i`ve teststed the program below and it works, the problem could be the onkeydown event. If you somehow change the text of the richedit in this routine undu will fail. Undo has a suspend resume method for it in richedit 3.0 but not in richedit 2.0. So there is a compatebilty problem with it. I`m now busy to write my own routines that work on all richedit versions.
Or write one in fnx basic.

best regards




object f as form
object menu as mainmenu
object meUndo as menuitem
    Caption = "Undo"
    Shortcut = "CTRL+Z"
    onclick = undo
end object
end object
object editor as richedit
    top=0
    left=0
    width=f.clientwidth
    height=f.clientheight-21
    borderstyle=bssingle
   `` onkeyup = formkeyup
    scrollbars=ssBoth
end object
showmodal
end object

sub undo
    editor.undo
end sub

hi, i`ve updatet the update section of the forum, if you use this compiler
the bug of the richedit undo function is gone.
