How to automatically add lines and scroll in CEdit?

Rostfrei29-Jan-06 21:42

Hello!

I want to implement some kind of history log with CEdit controll. But here is the problem; CEdit only have SetWindowText method. Is there a way to add just one line of text? Now I do multiple lines with text in string buffer separated by "\r\n". To add some line, I add text to this buffer and separate it with "\r\n" and after it I call SetWindowText on CEdit control. Here I have a problem how many srolls to do when I get ower the edit control visible lines limit.

Is there any better way? Just to add line of text and if out of visible lines srcoll just one line?

Best regards,

Rostfrei

I can think of two ways to add a line:
- Call GetWindowText, tack on the new line then call SetWindowText. This is somewhat inefficient.
- Use EM_SETSEL and EM_REPLACESEL messages which are wrapped by CEdit::SetSel and CEdit::ReplaceSel respectively.

I use this code:

m_EditRcvdMsg.SetSel(-1, 0); //select no text
m_EditRcvdMsg.ReplaceSel(pMsg);
m_EditRcvdMsg.SetSel(-1, 0); //select no text
m_EditRcvdMsg.ReplaceSel(_T("\r\n"));

//scroll into position
m_EditRcvdMsg.LineScroll(1);

Set this style on for the edit control ES_MULTILINE. And for scrollbars WS_HSCROLL and WS_VSCROLL.

Does anybody know how to check if a user is part of a WINNT group.

Sure, but you did not specify whether the group was local or global. Check out NetLocalGroupGetMembers() or NetGroupGetUsers().

detecting file access

sometimes it so happens that a process is accessing a file and it makes it uneditable or undeleteable. Is there a way by which we can detect which process is accessing the file? that way we could possibly kill it to enable file edition.

Save the points as you draw the ROI, use CreatePolygonRgn() to create a HRGN from those points, use PtInRegion() to determine if a point is inside your ROI.
