Question

finaly i could do the following
dim str as string = "RAJ"

Answer 1

i never worked on VB.NET but i can guess.

textbox1.select(int x, int y)

selects the string in textbox1 starting from x upto y.

x = starting character
y = end character

.........new answer ................

x = starting character
y = number of chars to be selected ..

is it ok now .. ?
