CHString::Mid(int, int) method

[The CHString class is part of the WMI Provider Framework which is now considered in final state, and no further development, enhancements, or updates will be available for non-security related issues affecting these libraries. The MI APIs should be used for all new development.]

The Mid method extracts a substring of length nCount characters from a CHString string, starting at position nFirst (zero-based). The method returns a copy of the extracted substring.

Syntax


void Mid(
   int nFirst,
   int nCount
) const throw (CHeap_Exception);

Parameters

nFirst

nCount

The number of characters to extract form this CHString string. If this parameter is not supplied, then the remainder of the string is extracted.

The Mid method is similar to the Basic MID$ function except in the Basic MID$ function, indexes are zero-based.
