[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
CHString throw(CHeap_Exception) Mid(
int nFirst
);
Parameters
nFirst
The zero-based index of the first character in this CHString string that is be included in the extracted substring.
Return value
Returns a CHString object that contains a copy of the specified range of characters. The returned CHString object may be empty.
Remarks
The Mid method is similar to the Basic MID$ function except in the Basic MID$ function, indexes are zero-based.
Examples
The following code example shows the use of CHString::Mid.
CHString s( L"abcdef" );
assert( s.Mid( 2, 3 ) == L"cde" );
