Hi. I made a text box....

Code:

ScriptWin = CreateWindow("EDIT", "" , WS_CHILD | WS_VISIBLE | ES_MULTILINE | WS_HSCROLL | WS_VSCROLL | ES_WANTRETURN, 5, 5, 600, 400, hWnd,(HMENU)ID_ScriptWin, NULL, NULL);

then i want to write to it

Code:

SendMessage(ScriptWin, WM_SETTEXT, 0, (LPARAM)(LPCTSTR)text2show.c_str());

text2show = string so i need the c_str()

my question is:

How I make it append the string into the textbox instead of overiding the whole thing?

Thanks.

Code:

text2show.append(extra);

SetDlgItemText(hWnd, ID_ScriptWin, text2show);

Read the text from the box first, and append it to the string you are adding to it. You can use SendMessage with WM_GETTEXT and WM_GETTEXTLENGTH to accomplish what you need. _________________ - Retired.
