EM_GETLINE
An application
sends an EM_GETLINE message to copy a line of text from an edit control and
place it in a specified buffer.
EM_GETLINE
wParam = (WPARAM) line; // line number to retrieve
lParam = (LPARAM) (LPCSTR) lpch; // address of
buffer for line
Parameters
line
Value of wParam.
Specifies the zero-based index of the line to retrieve from a multiline edit
control. A value of zero specifies the topmost line. This parameter is ignored
by a single-line edit control.
lpch
Value of lParam.
Points to the buffer that receives a copy of the line. The first word of the
buffer specifies the maximum number of characters that can be copied to the
buffer.
Return Values
The return
value is the number of characters copied. The return value is zero if the line
number specified by the line parameter is greater than the number of
lines in the edit control.
Remarks
The copied
line does not contain a terminating null character.
