PackDDElParam
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 |
|
); |
|
Parameters
msg
Specifies the
DDE message to be posted.
uiLo
Specifies a
value that corresponds to the Windows 3.x low-order word of an lParam
parameter for the DDE message being posted.
uiHi
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.
Remarks
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.
