ZeeGrid Control Message



An application sends a ZGM_UNLOCK message to authenticate the users ZeeGrid development license.

wParam = 0;                          //not used; must be zero
lParam = (LPARAM)(int) iUnlockCode;  //license authentication code


The value of lParam. The unlock code supplied with your ZeeGrid license and registration.

Return Values

This message does not return a value.


The ZGM_UNLOCK message should be sent to the first ZeeGrid window created in your application. This message should be sent before the ZeeGrid is displayed.

This message only needs to be sent once per application instance.

Failure to send the ZGM_UNLOCK message will cause the ZeeGrid to operate in the unlicensed evaluation mode.

Obviously, since ZeeGrid is now released freely, this message no longer does anything and is obsolete.
