PackDDElParam info  Overview  Group

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



Specifies the DDE message to be posted.
Specifies a value that corresponds to the Windows 3.x low-order word of an lParam parameter for the DDE message being posted.
Specifies a value that corresponds to the Windows 3.x high-order word of an lParam parameter for the DDE message being posted.

Return Values

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.
