EM_LINESCROLL
An application sends an EM_LINESCROLL message to scroll the text vertically or
horizontally in a multiline edit control.
EM_LINESCROLL
wParam = (WPARAM) cxScroll; // characters to scroll horizontally
lParam = (LPARAM) cyScroll; // lines to scroll vertically
Parameters
cxScroll
Value of wParam. Specifies the number of characters to scroll horizontally.
cyScroll
Value of lParam. Specifies the number of lines to scroll vertically.
Return Values
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 edit 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 cyScroll 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.
The EM_LINESCROLL message can be used to scroll horizontally past the last
character of any line.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
