There are 2 methods to store file location on database .
Use below codes just before saving to database.
You can assign converted Textbox value to itself, or any other string variable.
1. Just replace \ in file location value with \\
txtLocation.Text = Replace(txtLocation.Text, "\", "\\")
Note:- While retrieving data from Database, you did not need to convert \\ to \
2. Just replace \ in file location value with *(star symbol)
txtLocation.Text = Replace(txtLocation.Text, "\", "*")
Note:- While retrieving data from Database, you should convert * to \ before showing in Label or Textbox.
txtLocation.Text = Replace(txtLocation.Text, "*", "\")
