DdeCmpStringHandles function (ddeml.h)
Compares the values of two string handles. The value of a string handle is not related to the case of the associated string.
Syntax
int DdeCmpStringHandles(
[in] HSZ hsz1,
[in] HSZ hsz2
);
Parameters
[in] hsz1
Type: HSZ
A handle to the first string.
[in] hsz2
Type: HSZ
A handle to the second string.
Return value
Type: int
The return value can be one of the following values.
| Return value | Description |
|---|---|
|
The value of hsz1 is either 0 or less than the value of hsz2. |
|
The values of hsz1 and hsz2 are equal (both can be 0). |
|
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.
