Be aware that all is does is change to True whenever any change is made to the contents of the control since the last time Modified was set to False. So, after loading text in the control, you need to do Modified:=False. When you save the contents to a file and continue editing, you will probably reset Modified also.

I'm writing a program to modify text files. What I do is load the file in a RichEdit control (set to plain text only), and modify the data. Then I plan on saving it back out, if there were changes made. Unless I missed something, I can't find a property that flags this (e.g. RichEdit1.<whatever>). Then, on top of this, let's say the RichEdit control had "ZZZ" added to it, then I used CTRL-Z to remove it, which put it back to the way it was originally loaded. If there is such a property, will it figure out what it is still the same, since the CTRL-Z removed the "ZZZ"? Thanks in advance.
