Any existing uppercase letters and non-alpha characters remain unchanged. StrSubstr = Right$("Visual Basic", 3) ' strSubstr = "sic"Ĭonverts all lowercase letters in a string to uppercase. String expression from which the rightmost characters are returned. The Right$ function syntax has these parts: Returns a substring containing a specified number of characters from the end (right side) of a string. ' Note that the same thing could be accomplished with Mid$: StrSubstr = Left$("Visual Basic", 3) ' strSubstr = "Vis" If greater than or equal to the number of characters in string, the entire string is returned. If 0, a zero-length string ("") is returned. Numeric expression indicating how many characters to return. String expression from which the leftmost characters are returned. The Left$ function syntax has these parts: Returns a substring containing a specified number of characters from the beginning (left side) of a string. In VB6, the Replace$ function was introduced, which can also be used to replace characters within a string. Note: Mid$ can also be used on the left side of an assignment statement, where you can replace a substring within a string.
StrSubstr = Mid$("Visual Basic", 3, 4) ' strSubstr = "sual" If omitted or if there are fewer than length characters in the text (including the character at start), all characters from the start position to the end of the string are returned. If start is greater than the number of characters in string, Mid returns a zero-length string (""). Character position in string at which the part to be taken begins. String expression from which characters are returned. The Mid$ function syntax has these parts: Returns a substring containing a specified number of characters from a string. LngLen = Len("Visual Basic") ' lngLen = 12 Where string is the string whose length (number of characters) is to be returned. Returns a Long containing the length of the specified string

Also there are many other string related tutorials on this site so feel free to browse around.
If you are still confused feel free to post a comment and hopefully we can help get you cleared up. This tutorial will walk you through all the different ways you can us VB to handle strings. The first time I started trying to understand the VB6 string functions I was somewhat confused.
The functions that return strings can be coded with or without the dollar sign ( $) at the end, although it is more efficient to use the version with the dollar sign. Most VB string-handling functions return a string, although some return a number (such as the Len function, which returns the length of a string and functions like Instr and InstrRev, which return a character position within the string). VB has numerous built-in string functions for processing strings. Cleaned up and reformatted for this site.
