You can convert RichInk data that contains embedded drawings, bitmaps, or sound recordings, into Rich Text Format using a RichInk control.

To convert RichInk data into RTF

  1. Instantiate a RichInkwindow using the richink.dll library found in the your desktop computer's ActiveSync folder.

  2. Instantiate a COOKIEstructure (e.g., named "Cookie"), and an EDITSTREAMstructure (e.g., named "es").

    Copy Code 
    // Create a handle to the.pwi file.
Cookie.hFile   = hSrc;

es.dwCookie	= (DWORD)&Cookie;
es.dwError	 = 0;
es.pfnCallback = ReadCallback;

  3. Call EM_STREAMINon the ink window, with the read callback (see below) sourcing the data.

    Copy Code 
    // Load richink with the *.PWI file.
SendMessage (hwndInk, EM_STREAMIN, SF_UNKNOWN, (LPARAM)&es);

  4. Convert the data to RTF.

    Copy Code 
    // Create a handle to the output *.RTF file.
Cookie.hFile   = hDst;

// Zero-out the cookie.
es.dwCookie	= (DWORD)&Cookie;
es.dwError	 = 0;
es.pfnCallback = WriteCallback;

SendMessage (hwndInk, EM_STREAMOUT, SF_RTF, (LPARAM)&es);

Code Example

The following code example demonstrates the ReadCallback function.

Copy Code 
DWORD CALLBACK ReadCallback(DWORD dwCookie, LPBYTE pbBuff, LONG cb,
LONG *pcb)
{
	PCOOKIE pCookie = (PCOOKIE)dwCookie;
	*pcb			= 0;

	if (ReadFile(pCookie->hFile, pbBuff, cb, pcb, 0) == 0)
		return (pCookie->dwError = GetLastError());

	return 0;
}

Code Example

The following code example demonstrates the WriteCallback function.

Copy Code 
DWORD CALLBACK WriteCallback(DWORD dwCookie, LPBYTE pbBuff, LONG
cb, LONG *pcb)
{
	PCOOKIE pCookie = (PCOOKIE)dwCookie;

	if (WriteFile(pCookie->hFile, pbBuff, cb, pcb, 0) == 0)
		return (pCookie->dwError = GetLastError());

	return 0;
}
