The EM_STREAMIN message replaces the contents of a rich edit control with the specified data stream.
EM_STREAMIN
wParam = (WPARAM) (UINT) uFormat;
lParam = (LPARAM) (EDITSTREAM FAR *) lpStream;
Parameters
uFormat
One of the following data formats:
| Value | Meaning |
| SF_TEXT | Text |
| SF_RTF | Rich Text Format (RTF) |
Both data formats may be combined with the SFF_SELECTION flag. If the SFF_SELECTION flag is specified, the stream replaces the contents of the current selection. Otherwise, the stream replaces the entire contents of the control.
The SF_RTF format may be combined with the SFF_PLAINRTF flag. If the SFF_PLAINRTF flag is specified, language-specific RTF keywords in the stream are ignored. Only keywords common to all languages are streamed in.
lpStream
Pointer to an EDITSTREAM structure. The control reads (streams in) the data by repeatedly calling the function specified by the structure's pfnCallback member.
Return Values
Returns the number of characters read.
