EM_SCROLL Overview  Group

An application sends an EM_SCROLL message to scroll the text vertically in a multiline edit control. This message is equivalent to sending a WM_VSCROLL message to the edit control.


wParam = (WPARAM) (INT) nScroll;    // scroll action 

lParam = 0;                         // not used; must be zero 



Value of wParam. Specifies the action the scroll bar is to take. This parameter may be one of the following values:




Scrolls down one line.


Scrolls up one line.


Scrolls down one page.


Scrolls up one page.

Return Values

If the message is successful, the high-order word of the return value is TRUE, and the low-order word is the number of lines that the command scrolls. The number returned may not be the same as the actual number of lines scrolled if the scrolling moves to the beginning or the end of the text. If the nScroll parameter specifies an invalid value, the return value is FALSE.


An application should use the EM_LINESCROLL message to scroll to a specific line or character position.

An application should use the EM_SCROLLCARET message to scroll the caret into view.
