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.
