Hello again, I recently having my mainwindow write text by using WM_PAINT, but now I realise it was maybe not the best message to do so in, so I'm trying another version;

The mainwindow contains a menu, upon clicing a menu item the ID_FILE_PID msg is sent and it builds the 4 new windows aswell as displays text in the mainwindow (paintEditSigns function). The 4 windows works fine but the text dosn't work at all, unless I do it in the main() function as shown... what on earth is this? O_O

BTW: I still have no clue why the code-display on StackOverflow keeps looking so wierd when I post, why is this?

switch(message)
   {
   case WM_COMMAND:
     switch (LOWORD(wParam))
       {
            case ID_FILE_PID:
            {
                HWND hWndButton;    
                HWND hWndEdit;
                HWND hWndEdit2;
                HWND hWndDisplay;

                // drawing the text in mainwindow
                paintEditSigns();      --    does not do anything here!

                // adding new windows in the mainwindow
                hWndButton = CreateWindowEx(0,TEXT("BUTTON"),"Modify",WS_CHILD | WS_VISIBLE |
                BS_DEFPUSHBUTTON, 170,56,80,30,hWnd,(HMENU)ID_BUTTON,hThisInstance,NULL);   
                hWndEdit = CreateWindowEx(0,RICHEDIT_CLASS,TEXT(""),WS_CHILD | WS_VISIBLE | WS_BORDER,
                120,30,80,25,hWnd,(HMENU)ID_EDIT,hThisInstance,NULL);
                hWndEdit2 = CreateWindowEx(0,RICHEDIT_CLASS,TEXT(""),WS_CHILD | WS_VISIBLE | WS_BORDER,
                220,30,80,25,hWnd,(HMENU)ID_EDIT2,hThisInstance,NULL);
                hWndDisplay = CreateWindowEx(0,TEXT("STATIC"),NULL,WS_CHILD | WS_VISIBLE | WS_BORDER,
                0,100,450,140,hWnd,(HMENU)ID_DISPLAY,hThisInstance,NULL);


                break;
            }
