The Write SF function allows a client application to write structured field data to the host application.

Note:

The client must call the Set Structured Field Service Condition function before invoking the Write SF function.

The client sends the following message to write structured field data.

PostMessage( hServerWnd,
             WM_DDE_POKE,
             hClientWnd,
             MAKELONG(hData, aSF) );

where:

hData	Identifies a handle to a Windows global memory object containing: `typedef struct tagWRITESF { unsigned unused:12, // unsigned fRelease:1, // unsigned fReserved:3; // int cfFormat; // Always CF_DSPTEXT WORD uSFLength; // Length of SF data char Work[8]; // Work area char szSFData[1]; // SF data } WRITESF, FAR *lpWRITESF;`
aSF	Identified structured field as the item.
