hi,
I worked around to modifying regular expression below but i could't get what I need. I google it, many things found but not for what i want.
Dim valid AS Boolean = Regex.IsMatch(TextBox1.Text, "^(,?\d+){0,20}$")
Allow numbers exactly like 32,1,6,32,12,21,21,54,675,8,4,3,2,9,0,21,21,21,43,744 in TextBox1. Perfect.
NOW i want 20 numbers as but this time "real numbers" (of type double), separated by commas in TextBox2 like
(32.43343,1.43,6.0,32.434334,12.43432,21.8776,21.89,54.22,675.1232,8.453,4.5454,3.87,2.00,9.65,0.0,21.12,21.2,21.1,43.5,744.3633).
Please help me out.
thanks ...
