Log Window

[G26pX9L8]

Hallo

I have this piece of code and now I want to make a log system. It is intended that there is always a line when something happened, but how do I do that without the rest of the lines disappear devote?

This is de code now:

case WM_CREATE:
            CreateWindow(
                "EDIT",
                "",
                WS_CHILD | WS_VISIBLE | WS_HSCROLL | WS_VSCROLL | ES_MULTILINE | ES_WANTRETURN,
                CW_USEDEFAULT,
                CW_USEDEFAULT,
                CW_USEDEFAULT,
                CW_USEDEFAULT,
                hwnd,
                (HMENU)1001,
                g_hInst,
                NULL
            );
            SendDlgItemMessage(hwnd, 1001, WM_SETFONT, (WPARAM)GetStockObject(DEFAULT_GUI_FONT), MAKELPARAM(TRUE, 0));
        break;

How about saving all the lines within a container and draw the container to the window...

(I´m not sure, but I think there could be some flicker going on, when doing this - there is an solution to this in the MSDN for MFC-programs, but I don´t remember the link [it´s been a while])

I rather send every line alone to the window, but how to do?

[Incubbus]

How to send a line to an edit box, or how to avoid the flicker stuff?...

[G26pX9L8]

Send a single line to the edit box could i do with the function SetWindowText(); but if I send a new line, the old disappeard. Thats not what I want. How to continue?

[Computergeek01]

Step 1: Grab old text
Step 2: Append New Text
Step 3: Draw whole log to the window.

Alternativley

Dump all text to what we like to call a "log file", then read it back to your Edit box.

[G26pX9L8]

Really what the intention is that after each step is shown on screen what happened that should be posted in the edit box.

[Incubbus]

Yep... But as usual, programming isn´t just telling the computer what to do exactly...

You sometimes need to evolve the solution, and that is - in this case - the three-step-solution, geek01 suggested... (Or try another one)...



EDIT: for an Log-Window I suggest to make the Edit-Box read-only, so one is able to copy the text easily, but restrict writing access to it... (EM_SETREADONLY)...

all right, well I think it is solved for now, tnx all
