其中若MACHINE.m_bVisionEnable为true时，选中BST_CHECKED表示为1.BST_UNCHECKED为0.表示没有选中

2 CString /Compare

//引自MSDN

int Compare( LPCTSTR lpsz ) const;

Return Value

Zero if the strings are identical, < 0 if this CString object is less thanlpsz, or > 0 if this CString object is greater than lpsz.

Example

The following example demonstrates the use of CString::Compare.

// example for CString::CompareCString s1( "abc" );CString s2( "abd" );ASSERT( s1.Compare( s2 ) == -1 ); // Compare with another CString.ASSERT( s1.Compare( "abe" ) == -1 ); // Compare with LPTSTR string.
