CAppDialog: invalid program type

[Majid Rafei]

Hi.

I am creating a panel for trading and I use the:

CAppDialog

library.

When I attach the script to the chart I get the following message:

CAppDialog: invalid program type

I also test some other similar panel scripts which I am sure those scripts work correctly, but I get the same message for them!

Anyone know what is this message for?

Thanks.

Please note that, when I use the code as indicator, there is no problem and the panel is created and shown in the chart. But as you know, I can't use any trade order in an indicator!

I think that the message is for the program type :-D
Because I have found the following code in the source library:

switch(m_program_type)
{
    case PROGRAM_EXPERT:
        if(!CreateExpert(x1,y1,x2,y2))
             return(false);
        break;
    case PROGRAM_INDICATOR:
        if(!CreateIndicator(x1,y1,x2,y2))
             return(false);
        break;
    default:
        Print("CAppDialog: invalid program type");
        return(false);
}
