# DN_RESIZECONSOLE

The DN_RESIZECONSOLE event is sent to the dialog callback function after the console window size has changed (for example, when the user presses `Alt-F9`).

### Param1

0

### Param2

Pointer to a COORD structure containing the current size of the console.

### Return

`TRUE`.

### Controls

Control | Description
--- | ---
Dialog | This event apllies only to the dialog

### Remarks

The DN_RESIZECONSOLE message is useful in the case when a dialog can adapt to the current size of the console. An example of such functionality is the Find files dialog (`Alt-F7`).

### Example

Adaptation of Find File's (`Alt-F7`) dialog size when console size changes:

    case DN_RESIZECONSOLE:
    {
      COORD coord=(*(COORD*)Param2);
      SMALL_RECT rect;
      int IncY=coord.Y-DlgHeight-4;

      ...

      Info.SendDlgMessage(hDlg,DM_ENABLEREDRAW,FALSE,0);

      Info.SendDlgMessage(hDlg,DM_GETDLGRECT,0,(LONG_PTR)&rect);
      coord.X=rect.Right-rect.Left+1;
      DlgHeight+=IncY;
      coord.Y=DlgHeight;

      if (IncY > 0)
        Info.SendDlgMessage(hDlg,DM_RESIZEDIALOG,0,(LONG_PTR)&coord);

      for (I=0; I < 2; I++)
      {
        Info.SendDlgMessage(hDlg,DM_GETITEMPOSITION,I,(LONG_PTR)&rect);
        rect.Bottom+=(short)IncY;
        Info.SendDlgMessage(hDlg,DM_SETITEMPOSITION,I,(LONG_PTR)&rect);
      }

      for (I=2; I < 10; I++)
      {
        Info.SendDlgMessage(hDlg,DM_GETITEMPOSITION,I,(LONG_PTR)&rect);
        if (I==2)
          rect.Left=-1;
        rect.Top+=(short)IncY;
        Info.SendDlgMessage(hDlg,DM_SETITEMPOSITION,I,(LONG_PTR)&rect);
      }

      if (IncY <= 0)
        Info.SendDlgMessage(hDlg,DM_RESIZEDIALOG,0,(LONG_PTR)&coord);

      Info.SendDlgMessage(hDlg,DM_ENABLEREDRAW,TRUE,0);

      ...

      return TRUE;
    }
