_EdSendKey( ) API Library Routine
Simulates the key press associated with the ASCII character number specified by charNum.
void _EdSendKey(WHANDLE wh, int charNum)
WHANDLE wh; /* Handle of editing window. */
int charNum; /* Number of character. */
Example
The following example opens for editing a file specified by a parameter. It inserts a line of text, "Hello, World", by sending the individual characters with _EdSendKey( ). It then uses _EdSendKey( ) to send a carriage return and linefeed and to insert an ASCII escape character. Notice that the escape character isn't interpreted as "discard editing session."
