Xceed Zip for COM/ActiveX on x86/x64 Documentation
Sets the callback function that will handle an XceedZip instance's triggered events. In order to use this event notification technique, you must implement the callback function.
| Declaration | |
|---|---|
void XzSetXceedZipCallback( HXCEEDZIP hZip, LPFNXCEEDZIP lpfnCallback ) | |
| Parameter | Description |
|---|---|
| hZip | Handle to the instance you want to receive events from. |
| lpfnCallback | Pointer to your callback function that will handle events. See the remarks below for a declaration of this callback. |
Your callback function must be declared as follows:
void CALLBACK YourXceedZipEventProc( WPARAM wXceedMessage, LPARAM lParam )
The wXceedMessage parameter will contain the Xceed Zip event index, and lParam a pointer to an event parameter structure. In your callback function, you must typecast the lParam parameter to the correct structure, depending on the value of wXceedMessage.
