DdeCmpStringHandles info  Overview  Group

The DdeCmpStringHandles function compares the values of two string handles. The value of a string handle is not related to the case of the associated string.

int DdeCmpStringHandles(

    HSZ hsz1,

// handle to first string

    HSZ hsz2 

// handle to second string

   );

Parameters

hsz1
Identifies the first string.
hsz2
Identifies the second string.

Return Values

The return value can be one of the following values:

Value

Meaning

-1

The value of hsz1 is either 0 or less than the value of hsz2.

0

The values of hsz1 and hsz2 are equal (both can be 0).

  1

The value of hsz2 is either 0 or less than the value of hsz1.

Remarks

An application that must do a case-sensitive comparison of two string handles should compare the string handles directly. An application should use DdeCmpStringHandles for all other comparisons to preserve the case-insensitive nature of dynamic data exchange (DDE).

DdeCmpStringHandles cannot be used to sort string handles alphabetically.
