    Ok,

    I've added a statusbar to my Win32 app as follows:

    hStatusBar = CreateStatusWindow( WS_BORDER|WS_CHILD | WS_VISIBLE, NULL,hwnd,(UINT)IDC_STATUS_BAR );

    SendMessage(hStatusBar,SB_SETPARTS,5,(LPARAM)iStatusWidths);
    //print out the results strings

    sprintf(sb_freq,"Frequency: %d",(int)ref_freq);

    sprintf(sb_ref_amp,"Channel 1 Amp: %d",(int)ref_amp);

    sprintf(sb_las_amp,"Channel 1 Amp: %d",(int)las_amp);

    //create the statusbar SendMessage(hStatusBar,SB_SETTEXT,0,(LPARAM)" For Help press F1");
    SendMessage(hStatusBar,SB_SETTEXT,1,(LPARAM)sb_freq);
    SendMessage(hStatusBar,SB_SETTEXT,2,(LPARAM)sb_ref_amp);
    SendMessage(hStatusBar,SB_SETTEXT,3,(LPARAM)sb_las_amp);

    ========================================
    That code works fine, however I'm having problems updating the statusbar else where:

    For example, just as a test I tried updating the statusbar everytime the window was resized:

    case WM_SIZE:

    //change panel 0's message
    SendMessage(hStatusBar,SB_SETTEXT,0,(LPARAM)" For Help press F2");
    InvalidateRgn(hwnd, NULL, TRUE);
    break;

    bot nothing happens. I thought invalidateRgn would call WM_Paint and the new text would be written to the status bar. I 've also tried using SendMessage to call WM_PAint, but this also doesnt work....


    Any ideas??

    Thanks,
    Martin
