EM_GETLINE Overview  Group

An application sends an EM_GETLINE message to copy a line of text from an edit control and place it in a specified buffer.


wParam = (WPARAM) line;          // line number to retrieve 

lParam = (LPARAM) (LPCSTR) lpch; // address of buffer for 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.
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.


The copied line does not contain a terminating null character.
