EM_LINESCROLL message

Scrolls the text in a multiline edit control.

Parameters

wParam

Edit controls: The number of characters to scroll horizontally.

Rich edit controls: This parameter is not used; it must be zero.

lParam

The number of lines to scroll vertically.

Return value

If the message is sent to a multiline edit control, the return value is TRUE.

If the message is sent to a single-line edit control, the return value is FALSE.

Remarks

The control does not scroll vertically past the last line of text in the edit control. If the current line plus the number of lines specified by the lParam parameter exceeds the total number of lines in the edit control, the value is adjusted so that the last line of the edit control is scrolled to the top of the edit-control window.

Edit controls: The EM_LINESCROLL message scrolls the text vertically or horizontally in a multiline edit control. The EM_LINESCROLL message can be used to scroll horizontally past the last character of any line.

Rich Edit: Supported in Microsoft Rich Edit 1.0 and later. The EM_LINESCROLL message scrolls the text vertically in a multiline edit control. For information about the compatibility of rich edit versions with the various system versions, see About Rich Edit Controls.
