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
);
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. |
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.
