The PackDDElParam function packs a DDE lParam value into an internal structure used for sharing DDE data between processes.
LONG PackDDElParam(
UINT msg, |
// DDE message to be posted |
UINT uiLo, |
// low-order word of lParam of message |
UINT uiHi |
// high-order word of lParam of message |
); |
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
The return value must be posted as the lParam parameter of a DDE message; it must not be used for any other purpose. Once the application posts a return value, it need not perform any action to dispose of the lParam parameter.
PackDDElParam eases the porting of 16-bit DDE applications to 32-bit DDE applications.
An application should call this function only for posted DDE messages.
