In this lesson, you learned how to use the Trim method to remove space characters from both the beginning and end of a string. You can also use the Trim method to remove other characters. The syntax for doing this is string.Trim[(trimChars)]. The optional trimChars argument is a comma-separated list of characters that you want removed (trimmed). For example, if the txtInput control contains the string “#$456#”, you can remove the number signs and dollar sign from the control’s Text property using the statement txtInput.Text = txtInput.Text.Trim("#"c, "$"c). When processing the Trim method, the computer makes a temporary copy of the string in memory; it then removes the characters in the copy only. Open the VB2015\Chap08\ Trim Method Solution\Trim Method Solution (Trim Method Solution.sln) file. The btnTrim_Click procedure should remove any leading or trailing dollar signs, spaces, or percent signs. Test the application appropriately.
