Exactly what you've posted is correct. You simply use the "=" operator to compare two strings. Note that that will use the default behaviour with regard to character casing. You can also use the String.Compare method to force either a case-sensitive or -insensitive comparison.

The Compare method compares two strings and returns an integer value. The return value of Compare method can be less than zero, greater than zero or equals to zero.

[COLOR=#0000ff]Dim[/COLOR] str1 [COLOR=#0000ff]As[/COLOR] [COLOR=#0000ff]String[/COLOR] = "ppp"
[COLOR=#0000ff]Dim[/COLOR] str2 [COLOR=#0000ff]As[/COLOR] [COLOR=#0000ff]String[/COLOR] = "ccc"
[COLOR=darkgreen]'*declare a new variable that will hold the value *[/COLOR]
[COLOR=#0000ff]Dim[/COLOR] res [COLOR=#0000ff]As[/COLOR] [COLOR=#0000ff]Integer[/COLOR] = [COLOR=#0000ff]String[/COLOR].Compare(str1, str2)
MessageBox.Show("First result:" + res.ToString())
str2 = "ttt"
res = [COLOR=#0000ff]String[/COLOR].Compare(str1, str2)
MessageBox.Show("Second result:" + res.ToString())
str1 = "ttt"
res = [COLOR=#0000ff]String[/COLOR].Compare(str1, str2)
MessageBox.Show("Third result:" + res.ToString())
