I am using a rich text box.
Rich text box displays the contents from a text file.
I want user to write in the rich text box but no new character. Already displayed content should be over written and if he types correctly then it's color should be blue otherwise red.
In text box following contentx are displayed
ad sdf dfg
now first two characters ad are correctly types so they should appear in blue.
At 4th position instead of 's' he types 'd' so 'd' should be displayed in red and it should over write the 's'.
Now if user presses back space then original contents should appear
How to perform this?
Give the logic
I want to do this in VB6.0
