The substring.
If the substring is not present, or if you specify wStart as zero, MBSubstr2() returns a NULL_STRING.
Parameters
- cMBTarget
- Type: String
The string from which to extract a substring. - wStart
- Type: DWord
The starting position relative to the leftmost character in cMBTarget.
Return Value
Type: StringThe substring.
If the substring is not present, or if you specify wStart as zero, MBSubstr2() returns a NULL_STRING.
Remarks
MBSubstr2() is a typed version of MBSubstr().
The third argument of MBSubstr() which counts the number of characters is not allowed. Instead, this function starts at the specified location and extracts to the end of the string.
Also, because wStart cannot be negative, MBSubstr2() cannot extract a substring relative to the rightmost character of cMBTarget as can MBSubstr().
